The following points are recommended for plastic mold recruitment information: requirements for plastic mold production, number of plastic mold cavities, molding cycle time (seconds), and product complexity. 1. If the mold design coefficient is 7Km, the number of product cavities is large, and the forming cycle time is very short. 2. Injection speed and injection speed are somewhat faster than when molding a part with an injection mechanism. 3. Good dimensional stability Plastic product molds generally use a positive and negative zero fit, using a negative mold to reduce the molding cycle time of the product by half. 4. The release angle (negative difference) of plastic products should be minimized, and the mold design dimensions can be changed to facilitate product release. 5. The shrinkage rate is usually variable. 6. The shrinkage rate is usually variable. 7. When the mold release angle (negative difference) of a workpiece is large, the smaller the plastic part, the smaller the diameter of the plastic part, and the larger the diameter, the mold release angle also increases. The smaller the mold release angle, the greater the shrinkage. When the mold release angle of a plastic part is small and the shape is large, the mold release angle is also small for the plastic part. When the mold release angle of a plastic part is small, the shrinkage rate becomes larger. The internal stress of the plastic part decreases. Therefore, it is necessary to minimize the mold release angle or mold release angle of plastic parts. However, the release angle should be larger.

● When the wall thickness of the plastic part is small, the draft angle should be taken larger. Injection molding machine: The wall thickness is generally 05~15mm.
The release angle of plastic parts should be as small as possible. When plastic parts are easy to release, it is not advisable to choose a release angle with a large release angle. At the same time, it should be conducive to mold release.
● The thickness of plastic parts is taken as (1): the maximum shell pulling slope for uneven wall thickness of plastic parts is 1 °, and it can be taken as 2 ° larger when the plastic parts are relatively thick.
● The plastic parts should be symmetrical and should not be demoulded all at the same time, leaving a large margin. The inner and outer surfaces of the plastic parts should be flat. The wall thickness of the plastic parts should be uniform and uniform. Local supercooling is not allowed, otherwise it will contract differently.
● The structure and performance of plastic parts, the structure and performance of plastic parts, the wall thickness and performance of plastic parts, the structure and performance of plastic parts, the wall thickness and performance of plastic parts, the wall thickness and performance of plastic parts, and the structure and performance of plastic parts are as follows: The structure and performance of plastic parts should comply with production conditions, the structure, performance, and related process parameters of plastic parts, the structure and performance of plastic parts, and the structure and performance of plastic parts should be considered from the perspective of plastic structure design and research, For example, due to factors such as process cooling caused by molding, molding cooling, and glue injection processes, and the presence of process stresses inside plastic parts, plastic parts should be of two or three types of co plastic parts, four types of plastic parts, low quality plastic, heat resistant plastic, and plastic parts with a wall thickness and shape that are both different from those of one type of plastic, and the wall thickness should not be less than that of single plastic parts, small plastic parts, and several types of plastic parts.
