Description

Technical Field

[0001] This utility model relates to the field of injection molding equipment technology, specifically to an injection molding equipment for PE and PA plastic products. Background Technology

[0002] According to a patent published on the China Patent Network, the patent title is "A Plastic Product Injection Molding Device," and the patent application number is 202021941062.X. This utility model discloses a plastic product injection molding device, particularly relating to the field of plastic product injection molding technology. A buffer seat is fixed in the middle of the upper end of the worktable. The lower end of the lower mold extends into the buffer seat and is slidably connected to it. Sleeves are fixed at the four corners of the bottom of the buffer seat. A buffer spring is connected to the bottom of each sleeve. A sliding rod is slidably connected inside the sleeve. The lower end of the sliding rod is connected to the buffer spring, and the upper end of the sliding rod is fixed to the bottom of the lower mold. In this plastic product injection molding device, when the upper mold presses down on the lower mold, it causes the sliding rod to slide down into the sleeve. At this time, the sliding rod compresses the buffer spring, providing initial buffering. Simultaneously, a connecting rod pushes a guide block to slide along the guide rod, where the guide block compresses the second buffer spring, thus providing double buffering. This improves the buffering performance of the lower mold and avoids damage due to a poor buffering effect. The aforementioned plastic product injection molding equipment has poor cooling effect after injection molding, which prevents it from cooling down quickly for removal, resulting in low overall work efficiency.

[0003] Therefore, it is necessary to redesign and modify the injection molding equipment for plastic products to effectively prevent the inability to quickly cool the finished product after injection molding. Utility Model Content
