Injection molding machine with raw material preheating function and using method thereof

Abstract

The invention relates to the technical field of injection molding machine preheating, and particularly relates to an injection molding machine with a raw material preheating function and a using method thereof. The injection molding machine comprises a preheating inclined frame, wherein the lower end of the preheating inclined frame is fixedly installed on a supporting base, and a first rotating pipe and a second rotating pipe are obliquely and rotationally installed on the preheating inclined frame downwards. The injection molding machine has the beneficial effects that the rotating pipes with spiral flow grooves are arranged, so that raw material particles are driven to obliquely fall through spiral rotation while preheating is realized, meanwhile, sectional heating is utilized, so that the heating temperature is convenient to control, and the raw material particles are prevented from being bonded; a U-shaped water pipe is arranged to communicate with an injection molding machine cooling device, so that heat is fully utilized; meanwhile, the particles slide on a heat conduction plate in an inclined mode, so that the particle raw materials are fully heated; and inclined upward installation is matched, so that sectional preheating from low temperature to high temperature is realized, and the preheating quality is greatly improved.

Description

technical field [0001] The invention relates to the technical field of injection molding machine preheating, in particular to an injection molding machine with a raw material preheating function and a use method thereof. Background technique [0002] Injection molding machine is also known as injection molding machine or injection machine. It is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products using plastic molding molds. Divided into vertical, horizontal, all-electric. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it shoot out and fill the mold cavity. [0003] When the injection molding machine heats the plastic, due to the high heating temperature of the injection molding machine, the plastic will easily cause the outer wall to paste when the temperature difference is large, but the inside cannot be melted. Therefore, it is necessary to fully ...

AI Technical Summary

Problems solved by technology

[0003] When the injection molding machine heats the plastic, due to the high heating temperature of the injection molding machine, the plastic will easily cause the outer wall to paste when the temperature difference is large, but the inside cannot be melted. Therefore, it is necessary to fully preheat before heating, so that The plastic particles are softened first and then heated and melted to form a molten plastic. However, the existing preheating device needs additional heat consumption, and at the same time it is difficult to control the temperature, and lacks a propulsion device. Once the preheating temperature is too high and the plastic melts, it is very easy to cause the plastic Bonding in the preheating device, so that the raw materials cannot enter the heating and melting station

[0004] To this end, an injection molding machine with raw material preheating function and its use method are provided to solve the problem of plastic preheating and feeding
