Efficient-dehumidification injection molding machine

Abstract

The invention discloses an efficient-dehumidification injection molding machine. The efficient-dehumidification injection molding machine comprises a base, an extrusion module and a mold module, wherein the extrusion module and the mold module are installed on the base. The extrusion module comprises a stuff canister, an extrusion screw and an injector head, wherein the extrusion screw and the injector head are arranged inside the stuff canister. A hopper is arranged on the upper right portion of the stuff canister, and a humidifier is arranged on the middle upper portion of the stuff canister. The left end of the extrusion screw is connected with the injector head, the right end of the extrusion screw is connected with a motor, and a pushing spiral blade is arranged on the outer wall of the extrusion screw. A material channel is arranged inside the injector head, the left end of the material channel is connected with the mold module, and the right end of the material channel communicates with an inner cavity of the stuff canister. The mold module comprises a fixed mold arranged on a mold right supporting seat, a movable mold arranged on a left supporting seat, a supporting seat guide rod and a position adjusting oil cylinder. The right supporting seat is fixed to a sliding seat, the left supporting seat can move leftwards and rightwards on the sliding seat, and the sliding seat can slide leftwards and rightwards on the base. The fixed mold is provided with a feeding port connected with the material channel of the injector head. The efficient-dehumidification injection molding machine can substantially reduce the moisture content of plastic materials and improve product quality.

Description

technical field [0001] The invention relates to the technical field of plastic processing, in particular to a high dehumidification injection molding machine. Background technique [0002] Injection molding machine is the main molding equipment for making thermoplastics or thermosetting materials into plastic products by plastic molding molds. The injection molding process is generally to process materials such as polymers to a plasticized molten state, and with the help of the thrust of the screw or plunger, the The raw material is extruded from the barrel into the mold, and the product is obtained after curing and shaping. The volatile matter and water vapor in the plastic smelting process of the existing injection molding machine cannot be discharged in time, resulting in defects such as air bubbles, fish eyes, yellowing, black spots, and joint lines in the product. In addition, when the existing injection molding machine is used for injection molding, it is necessary to...

AI Technical Summary

Problems solved by technology

The volatile matter and water vapor in the plastic melting process of the existing injection molding machine cannot be discharged in time, resulting in defects such as air bubbles, fish eyes, yellowing, black spots, and joint lines in the product

In addition, when the existing injection molding machine is used for injection molding, it is necessary to drive the injection cylinder to move to the left, so that the nozzle and the mold inlet are assembled, and then plastic is injected into the mold. Due to the problem of equipment accuracy, the nozzle and the mold inlet often cannot be positioned accurately. question
