Window handle spacer secure Plastic Injection Molding Service

Window handle spacer secure Plastic Injection Molding Service

Window handle spacer are a versatile plastic product widely used in various structures.In order to improve the efficiency of mold design and product manufacturing accuracy, UG software is used to combine software modeling technology with Mold Wizard parting technology to achieve digital mold structure design. During the product trial molding process, compare and optimize multiple process parameters to improve the design efficiency and accuracy of the mold, and ensure the production quality of the product.

Window handle spacer is a commonly used plastic accessory in automobiles, often used to make reserved holes on car panels. The gasket is designed with inverted buckles on both sides for easy installation and clamping. The material used for the armrest gasket on a certain type of car in China is a mixture of Acteal. This material possesses excellent properties of hybrid materials, including significant formability, mechanical properties, impact strength, temperature resistance, and UV resistance. After injection molding, the product has good comprehensive performance, high impact strength, good chemical stability, and good fusion performance with 372 organic glass.

1. Product structure and process analysis

The product is made of Acteal raw materials into plastic parts, and the surface can be chrome plated and painted. Figure 1 shows a schematic diagram of the structure of a window handle gasket.

Option 1, using a latent gate mould structure,In this structural design.(1) The feeding gate is usually hidden on the inner surface or side of the plastic part, which does not affect the appearance of the product. (2) After the product is formed, it will automatically break with the plastic part during ejection. Therefore, it is easy to achieve production automation. (3) Due to the fact that the latent gate can be set on ribs and columns that are not visible on the surface of the product, it will not leave spray marks and air marks on the surface of the product during molding.

2.Parting surface design

The selection of the position and shape design of the parting surface is directly related to the complexity of the mold structure, the quality of the mold parts, the working status, and the convenience of operation. Therefore, the design of the parting surface is the most important link in mold design. The principles that should be followed in selecting the parting surface are: (1) convenient demolding of the product; (2) Leave the product on the side of the moving mold during demolding, making it easier to remove the product and ensure smooth exhaust of the mold cavity; (3) The gas discharge from the mold cavity mainly relies on the parting surface, and the exhaust groove is generally designed on the mold parting surface; (4) Ensure that the appearance of the product is undamaged, or cause burrs to appear on the end face of the product, and remove them without damaging the appearance of the product; (5) Lateral core pulling, designing the lateral core pulling on one side of the moving mold to simplify the mold structure .

4 Product trial molds

The function of product trial molding is to inspect the smoothness of mold production and ensure the smooth production of the product. Reasonable operating steps must be followed during the trial molding process, and useful technical parameters must be recorded during the trial molding process. At the same time, record and analyze the dimensional differences between different products, such as whether the product size is stable, the trend of certain size changes, whether size changes are within the tolerance range, and so on. These data records and analysis materials can provide reference basis for later mold repair and mass production. After completing the trial mold, save all sample inspection records during the trial mold process, such as various pressures during the processing cycle, glue and mold temperatures, material tube temperatures, injection action time, and screw feeding period.
