Description

Technical Field

[0001] The invention relates to the technical field of plastic injection molding, in particular to a plastic product injection molding mold. Background Art

[0002] Plastic products are a general term for daily and industrial products made of plastic as the main raw material, including products made of plastic using injection molding, vacuum forming and other processes. When producing and processing plastic products, injection molding is generally used to complete the processing and production operations. When plastic is injected, different injection molds need to be used according to the shape and structure of the plastic product.

[0003] The existing Chinese patent with authorization announcement number CN117532805B discloses a home appliance shell injection molding mold, including a bracket, a male mold and a female mold. The male mold is slidably mounted on the bracket, and the female mold is fixedly mounted on the bracket to form an injection cavity between the bracket and the male mold. A shell is fixedly mounted on one side of the female mold, and a plurality of evenly distributed electric heaters are installed on the side wall of the shell. A hopper is fixedly connected to the upper end of the shell, and a conveying mechanism is installed in the shell. The conveying mechanism is used to convey molten plastic and can pressurize the plastic injected into the injection cavity. A mounting port is opened on one side of the female mold, and a mounting block is fixedly connected to the mounting port, and an exhaust mechanism is installed in the mounting block. The invention can pressurize and push the plastic in the cavity, so that the plastic is subjected to sufficient pressure to avoid hollowing and affect the quality of the plastic finished product. At the same time, the air in the cavity can be efficiently discharged to avoid blockage of the exhaust channel.

[0004] However, the injection molding die has the following defects when used specifically:

[0005] 1. When the existing injection molding mold is used to process plastic products, it is necessary to heat the plastic granular raw materials to soften the plastic granular raw materials, and then transfer the softened plastic materials to the inside of the mold by extrusion to realize the automatic production and processing of plastic products. However, for the softening operation of the plastic raw materials, due to the different sizes of the plastic raw materials, some of the plastic raw materials may not be softened completely during the softening operation by heating, which affects the effect of the injection molding of the plastic products, and the quality of the molded plastic products is poor;

[0006] 2. When existing injection molding molds are used to produce and process plastic products, generally only a single plastic product can be used for injection molding at one time. At this time, when a large batch of plastic products are produced and processed, it is necessary to purchase several injection molding devices, which is costly. When one or a small number of injection molding devices are used for injection molding of plastic products, the production and processing efficiency of plastic products is low.

The gaps between different plastic raw materials during softening and injection molding are smaller, and the quality of the injection molded products after injection molding is better;

[0049] 4.
