Technical Field
[0001] This utility model relates to the field of injection molding machine technology, specifically to an automatic feeding injection molding machine. Background Technology
[0002] Injection molding machines, as essential equipment in modern manufacturing, are widely used in the production of plastic products. During the operation of an injection molding machine, the precise and efficient delivery of raw materials is one of the key factors ensuring product quality and production efficiency. Automatic feeding technology was developed to solve this problem. Utilizing advanced mechanical transmission and control systems, it achieves fully automated operation from raw material storage and metering to delivery, greatly improving the production efficiency and product quality of injection molding machines. At the same time, automatic feeding technology also reduces manual intervention and lowers production costs, making it an indispensable component of modern injection molding machines.
[0003] In traditional injection molding machine feeding technology, raw material delivery often relies on manual operation or simple mechanical devices. This feeding method is not only inefficient but also makes it difficult to achieve accurate metering and delivery of raw materials, leading to unstable product quality and low production efficiency. Furthermore, traditional feeding technology also causes raw material waste and environmental pollution, posing significant challenges to the sustainable development of enterprises. More seriously, due to the uncontrollability of manual operation, traditional feeding technology also presents safety hazards, posing a potential threat to the lives and property of production personnel. Therefore, the shortcomings of traditional injection molding machine feeding technology have severely restricted the development of modern manufacturing, urgently requiring technological innovation and upgrading.

[0035] Working Principle: First, driven by the servo motor 6, the worm gear 5 begins to rotate. The meshing of the worm gear 5 with the worm wheel ring 4 allows the feeding hopper 3 to be precisely adjusted around one end of the support frame 2. This adjustment ensures that the feeding hopper 3 can feed the raw material into the designated position of the injection molding machine body 1 at an appropriate angle, thus achieving the initial directional conveying of the raw material. Next, the second servo motor 8 starts, driving the movable rod 9 to rotate. The movable rod 9 is connected to the swing arm 12 through the linkage rod 10, thereby realizing the reciprocating swing of the swing arm 12. This swinging motion of the swing arm 12 allows it to periodically tumble or push the raw material in the feeding hopper 3, ensuring the smooth flow and uniform distribution of the raw material and avoiding blockages or jamming. In addition, the injection molding machine body 1 is also equipped with a gear transmission system driven by the forward and reverse motors 18. The forward and reverse motors 18 drive the gear 16 to rotate, thereby driving the meshing gear rod 14 and the second gear rod 15 to rotate in opposite directions. This rotational motion, transmitted through the linkage arm 21 and the second linkage arm 22, enables the discharge baffle 19 and the second discharge baffle 20 to open and close synchronously. When the cross-sections of the discharge baffle 19 and the second discharge baffle 20 completely overlap, they together form a complete circular channel, allowing the raw material to smoothly fall from the bottom feed port of the feeding funnel 3 into the injection cavity of the injection molding machine body 1. When they separate, they effectively block the flow of raw material, achieving precise metering and timed delivery of the raw material.
