Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a slide-implanted leather material forming mold. Background Art

[0002] Injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. Injection molding machine types generally include horizontal machines, vertical machines, and angle machines. According to the analysis of the mold industry, the vast majority of injection molding machines are horizontal machines, and there are very few vertical machines and angle machines, or even none, because they are not practical. When some special products require the use of vertical machines for better production, there are often no vertical machines or the limited number of vertical machines in the factory that cannot meet the needs of mass production, which leads to the passive development of product development and mold design, and the product may have to stop development. If the mold structure is improved from other aspects to assist in improving the problem of no vertical machine, it will inevitably complicate the mold structure and increase the mold cost. The quality and yield of the product will also inevitably be affected accordingly.

[0003] The application of molds has a great influence on the quality and yield control of products, especially for molds that need to place inserts. When using a vertical machine, the inserts are placed horizontally, and the positioning accuracy and stability of the inserts are better for injection molding production; if a horizontal machine is used, the inserts are placed vertically. Due to their own weight, the inserts are easy to fall or deflect, resulting in the quality of the injection molded products not meeting the expected requirements. For this reason, we propose a slide-implanted leather molding mold to solve the above problems. Utility Model Content

The arrangement of the air ducts on the front mold frame can be selected according to the processing method, and the air duct arrangement that is easiest to process is preferred.

[0010] As a further description of the above technical solution: the bottom end of the adsorption head is flush with the bottom of the inner side of the molding cavity, and the cross-sectional shape of the adsorption head includes but is not limited to a rectangle and a circle. The bottom end of the adsorption head is flush with the bottom of the inner side of the molding cavity to avoid the end of the adsorption head from extending out and interfering with the placement of the fitting.

[0011] As a further description of the above technical solution: a top material assembly located at the bottom of the rear mold frame is provided on the top of the base plate, and the top material assembly is located between two groups of square irons.

[0030] As a further implementation scheme of the above technical scheme: the number of adsorption heads 9 is 2-4 groups, and the adsorption heads 9 are evenly distributed in the molding cavity 8. The embedded part 13 is adsorbed by multiple groups of evenly distributed adsorption heads 9 to ensure the stability of the position of the embedded part 13 in the molding cavity 8, prevent the embedded part 13 from moving during the injection molding operation, and ensure the final quality of the embedded product.
