High-performance plastic injection molding machine with cooling device and injection molding method

Abstract

The invention relates to the field of plastic production equipment, in particular to a high-performance plastic injection molding machine with a cooling device and an injection molding method. Heatingdevices are uniformly arranged on the outer wall of a first conveying channel in the circumferential direction and extend from the upper end to the lower end of the first conveying channel; materialis uniformly heated in the first conveying channel; a buffering cabin mechanism is arranged to ensure feeding continuity; a fixed die and a moving die are arranged in an injection molding mechanism; afeeding runner opening is formed in the fixed die; material enters an injection molding die through a nozzle and the feeding runner opening sequentially; a first transverse air cylinder drives the moving die and the fixed die to be splitted and assembled so as to finish circulation of injection molding production; the cooling device is arranged in the moving die, is excellent in cooling effect, accelerates cooling of a finished injection molding product and improves the working efficiency; a thermal insulating cover is arranged to carry out excellent thermal insulation on molten fed materialat the nozzle and facilitates following injection molding processing; and during the injection molding process, the injection molding effect is excellent, the surface of the finished product is uniform, the yield of the finished product and the production efficiency are high, and the production demand of an enterprise is met.

Description

technical field [0001] The invention relates to the field of plastic production equipment, in particular to a high-performance plastic injection molding machine with a cooling device and an injection molding method. Background technique [0002] Plastic injection molding machine refers to the main molding equipment that uses plastic molding molds to make thermoplastic or thermosetting materials into plastic products of various shapes. The plastic injection molding machine needs to heat the conveying pipe while conveying the plastic melt through the conveying pipe. In the past, the electric heating tube is generally used for heating, and the heating effect is poor and the heating is uneven; the cooling effect of the cooling device is not good, and There is no protective device for the nozzle, so the molten plastic under the action of the cooling device is easy to cool down, which will affect the injection molding of the finished product; during the injection molding process, ...
