What is Precision Square Mold?
Precision square mold involves a highly technical process that requires the use of specialized molds and injection molding machines. Compared to traditional injection molding methods, it can be used for more complex geometries. Precision square mold is used for making complex plastic parts and products.
Precision square mold is mainly used to create complex plastic parts and products that can replace high-precision metal parts. This molding process can create various products.
Benefits of Precision Square Mold
Wear resistance
During plastic deformation in the precision square moldcavity, the blank flows and slides along the surface of the cavity, causing severe friction between the surface of the cavity and the blank, resulting in the failure of the mold due to wear. Therefore, the wear resistance of the material is one of the most basic and important properties of the mold.
Strong toughness
Most of the working conditions of precision moulds are very bad, and some often bear large impact loads, resulting in brittle fracture. In order to prevent sudden brittleness of mold parts during operation, precision metal molds must have high strength and toughness.
Fatigue fracture performance
During the working process of precision moulds, fatigue fracture is often caused under the long-term action of cyclic stress. Its forms include small energy multiple impact fatigue fracture, tensile fatigue fracture, contact fatigue fracture and bending fatigue fracture.
High temperature performance
When the working temperature of the precision square moldis high, the hardness and strength will decrease, resulting in early wear of the mold or plastic deformation and failure. Therefore, the precision metal mold material should have high anti-tempering stability to ensure that the mold has high hardness and strength at working temperature.
Type of Precision Square Mold
Injection Molding
These molds are used for producing plastic parts with high repeatability and precision. They are made from steel or aluminum and have a cavity that shapes the part when molten plastic is injected under high pressure.
Extrusion Molding
For continuous production of square profiles in materials like plastics, metals, or wood, extrusion molds are used. The material is forced through a die to create a uniform cross-section.
Die Casting
Die cast molds are used to produce non-ferrous metal parts with complex shapes and excellent surface finishes. The metal is melted and then injected into the mold under high pressure.
Compression Molding
Compression molds are used for thermosetting plastics and rubber materials. The mold is preheated, and the material is placed inside and subjected to high pressure and heat until it cures.
Application of Precision Square Mold
Automotive industry
Precision square molds are widely used in the manufacturing of various components such as engines, chassis, and vehicle bodies in the automotive manufacturing process. To achieve high-precision production of complex parts and improve the quality and performance of automobiles. For example, the manufacturing of engine cylinder blocks requires the use of die-casting molds to ensure cylinder accuracy and sealing.
Aerospace industry
Precision square molds are particularly important in the aerospace field. The manufacturing of aircraft engines involves a large number of high-temperature alloy parts, and the processing requirements for these parts are very high. precision square molds can ensure the accuracy and quality of these parts, improve the performance and reliability of the engine.
Electronic Industry
In the manufacturing process of electronic products, precision square molds are widely used in the manufacturing of semiconductor chips, electronic component packaging, and other links. The manufacturing of semiconductor chips requires the use of photolithography molds to achieve micron level linewidth and high-density integrated circuits.
Medical equipment industry
Precision square molds play an important role in the manufacturing of medical equipment. For example, the manufacturing of artificial joints requires the use of precision square molds to ensure joint accuracy adaptability. In addition, the manufacturing of medical devices requires the use of precision square molds to ensure product quality and safety. By using Kaidi molds for design and production, the product quality is absolutely guaranteed.
Materials and heat treatment control
Mould parts heat treatment to make parts needed to get the material hardness at the same time, and to make the parts after machining process and stable size shape, according to the characteristics of different parts of materials and parts structure has different way of heat treatment, must to control stress in heat treatment of parts to make heat treatment process, we must give full consideration to the material hardenability hardenability heat-sensitive and decarburization sensitivity, to adopt pressure quenching process of thin-walled parts.
Preparation for wire cutting
Precision slow-moving wire cutting machine tool is selected for wire cutting, with processing precision ±0.001mm and roughness Ra=0.2um. The perpendicularity of deionized water wire cutting wire with high degree of deionization meets the requirements of processing precision. The material of wire used for proper tensioning force cutting is suitable for the material of the workpiece to be cut to ensure a reasonable processing speed.
The processing route design
Wire-cutting processing on the material of the original stress balance is destroyed in the process of machining, cause stress concentration around the corner, processing method of stress concentration, by using the principle of the vector translation, finish machining allowance for 0.8 ~ 0.9 mm, before rehearsals cavity rough shape, and then to heat treatment, machining stress release before finishing, as far as possible to ensure that the thermal stability. 4 times of cutting shall be adopted in the processing of punch. The cutting wire cutting position and path shall be reasonably determined and the clamping blank position shall be selected after the first feeding.
EDM forming process
Rough and fine electrodes should be made in EDM forming process respectively. Fine electrode is machined by CNC CNC machine, alloy electrode has good comprehensive performance, and the electrode loss is very small compared with that of red copper. Under good chip removal conditions, it is difficult to process materials and parts with complex cross section shapes. Ag-w alloy electrode has better performance than Cu-W alloy electrode, which can be used in precision machining. Graphite electrode is made of imported graphite with small loss, high hardness, fast electric erosion and low surface roughness. Before the end of EDM, fine gauge finishing is arranged to remove the hardened thin layer formed on the surface.
How Does Precision Molding Work?
The mold used to manufacture polymer optics includes the cavity details, optical inserts, and housing to hold the cavities and inserts. Optical and mechanical features may be combined into one platform with polymer optics, which may lead to a mold with high complexity.
Molds are built to the negative of the final part, and the mechanical features of the part are drafted for easy removal once the molding process is complete. Most optical inserts are created from nonferrous alloys that are diamond turned for high accuracy.
The optical injection molding machine, called a press, includes a fixed and a moving platen, a clamping unit, and an injection unit. The mold is placed on the press with one half mounted to the fixed platen, and the other half is mounted to the moving platen. Plastic pellets are melted, fed into the injection unit, and injected into the mold.
Injection molding uses complex variables and controls. Without a robust process, even the best mold will experience drift from tool wear, changes in ambient conditions, fluctuations in resin content, and more. This is why it's essential to find an optics manufacturer with a high degree of skill in scientific molding techniques.
What are precision square mold Components?
Precision square mold components refer to various parts that are used to assemble a precision square mold. These components are designed and manufactured with utmost accuracy because they play critical roles in the functioning of the mold, and ultimately in determining the precision and quality of the molded product.
Mold cores and cavities
These form the inner surfaces of the mold where the material is injected to form the final product.
Guide Pins and Bushings
Used to align the two halves of the mold and ensure smooth movement during opening and closing.
Ejector Pins
Once the material has cooled and hardened, these pins help to eject the final molded product from the mold.
Sleeves, Slides, and Interlocks
Used to create complex geometries in the parts, and to ensure proper alignment and locking of mold halves.
Springs and other mechanical components
Used in the mold's functioning and movement mechanisms.
Hot Runner Systems
Used in some molds to control the flow of plastic in the mold, which can reduce waste and increase efficiency.
Maintenance and cleaning of precision square mold
1. The mold must be sharpened after long-term use. The edge surface must be demagnetized after grinding and cannot be magnetic, otherwise it is easy to cause material blockage.
2. Springs and other elastic parts are most easily damaged during use, and usually break and deform. The solution is to replace them. During the replacement process, you must pay attention to the specifications and models of the springs. The specifications and models of the springs are confirmed by color, outer diameter and length. Only when the three items are the same can they be replaced.
3. During the use of the mold, the punch is prone to breakage, bending and gnawed, and the punch sleeve is generally gnawed. The damage of the punch and the punch sleeve is generally replaced with parts of the same specifications. The parameters of the punch mainly include the working part size, installation part size, length size, etc.
4. Fasten the parts and check whether the fastening parts are loose or damaged. The solution is to find parts of the same specifications for replacement.
5. Pressing parts such as pressing plates, PU rubber, etc., unloading parts such as stripping plates, pneumatic ejectors, etc. During maintenance, check the relationship between the accessories of each part and whether there is any damage, repair the damaged part, check the pneumatic jack for leakage, and take measures according to the specific situation. If the air pipe is damaged, replace it.
