Description

Technical Field

[0001] The utility model relates to the field of injection molding machines, and more specifically, to a device for adding raw materials into injection molding machines. Background Art

[0002] Injection molding machine is a kind of equipment used to produce plastic products. It uses plastic molding molds to make thermoplastic or thermosetting plastics into products of various shapes. Injection molding machine, also known as injection molding machine or injection machine, is often referred to as "beer machine" in industry, and the plastic products it produces are called "beer parts". The main function of this equipment is to heat the plastic to a molten state, and inject it into the mold under high pressure, and then cool and solidify to form the desired plastic product.

[0003] The injection molding machine raw material box, also known as the hopper or material box, is a key component for storing plastic particles and conveying them to the inside of the injection molding machine. At present, the injection molding machine raw material box requires people to continuously add injection molding machine raw materials to the material box, which is rather troublesome. Therefore, a larger feeding box is often set on the raw material box, and sufficient raw materials are added to the feeding box. The bottom opening of the feeding box is repeatedly opened through the mechanical parts on the feeding box for intermittent feeding, which reduces the frequency of manual feeding to a certain extent. However, blockage problems often occur, and frequent manual participation is still required, and the feeding efficiency is low. Utility Model Content

The granular raw materials of the injection molding machine are then moved to the side of the injection molding machine, so that the feeding slot seat 2 is placed directly above the raw material box of the injection molding machine. In the initial state, the unblocking and feeding component 8 closes the through slot 3 at the bottom of the feeding slot seat 2. When the unblocking and feeding component 8 is running, the through slot 3 at the bottom of the feeding slot seat 2 will be opened repeatedly, thereby intermittently feeding and slowly adding the raw materials into the raw material box of the injection molding machine, which reduces the frequency of manual feeding to a certain extent (it should be noted that the volume of the feeding slot seat 2 on the actual equipment is very large and can accommodate a lot of granular raw materials).
