Energy-saving type injection molding equipment used for double-sided injection molding and capable of preventing raw materials from overflowing

Abstract

The invention relates to the technical field of plastic injection molding equipment, in particular to energy-saving type injection molding equipment used for double-sided injection molding and capableof preventing raw materials from overflowing. The energy-saving type injection molding equipment comprises an equipment body, an injection pipe is fixedly connected to the right side face of the equipment body, a screw rod is inserted into the injection pipe, the right end of the screw rod is connected with a fixing plate in a sleeved mode, a feeding hopper is inserted into the upper surface of the injection pipe, and a gas treatment box is fixedly connected to the position, located above the injection pipe, of the lower surface of the equipment body. A shielding plate is made to move towardsthe outer side of a limiting plate, so that an injection molding opening is blocked by the shielding plate, the problem that residual materials in the injection pipe can flow out through the injection molding opening is solved, meanwhile, materials are prevented from flowing back in the injection molding process, a conducting strip on a limiting spring cannot be connected with a second interfaceof a circuit tube through centrifugal force generated by the equipment, so that a signal lamp on the upper surface of the injection pipe is off, workers are reminded to maintain the equipment, and theproduction quantity of defective goods is reduced.

Description

technical field [0001] The invention relates to the technical field of plastic injection molding equipment, in particular to an energy-saving injection molding equipment used for double-sided injection molding to prevent overflow of raw materials. Background technique [0002] Injection molding is a method of producing shapes for industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding molding method and die-casting method. At present, the injection devices of general injection machines on the market adopt the method of direct feeding. [0003] However, in the process of feeding the existing equipment, the residual material in the injection tube will flow out through the injection port, resulting in waste of material. In addition, the injection speed is insufficient, and the material inside the mold is not enough, which easily leads to poor molding of the product. Complete...
