Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of injection molds, and more specifically, to a terminal embedded injection mold structure. Background Art
[0002] Injection molding is the most common molding method in the production of thermoplastic products. The mold used is a plastic injection mold, referred to as an injection mold. The processing equipment corresponding to the injection mold is a plastic injection machine (also known as an injection molding machine). Plastic products with metal embedded parts are relatively common in industrial applications. How to ensure that the metal embedded parts are reliably and efficiently positioned and stably produced? For example, the one-piece multi-terminal embedded injection mold disclosed in the prior art announcement number (CN209289668U) places the one-piece multi-terminal embedded part into the rear mold core, and manually pushes the slider to reset and ensure that the terminal pins are inserted into the sockets on the slider. The injection molding machine closes the mold. At this time, the shovel on the front mold presses the slider to prevent the slider from retreating under the injection pressure; after the injection molding machine locks the mold, the needle valve of the needle valve hot runner system opens to start injection and pressure holding. After the pressure holding is completed, the needle valve closes and the product cools, completing the entire injection molding process.
[0003] When the above-mentioned device is in use, it can increase the convenience of installation and positioning of the terminal metal embedded parts, maintain the stability of injection molding, improve the production yield of the product, save molding costs, and improve production efficiency. However, when the terminal embedded parts are installed and injection molded, the injection molding material will stick to the upper end of the terminal embedded parts. When discharging, the terminal embedded parts are easily detached from the upper end of the bottom mold, which is easy to affect the stability of the terminal embedded parts during discharging.
