Abstract

The invention provides a plunger type injection molding device, comprising an actuating motor, a gearing, a transmission part, a ball screw, a ball nut, an oil hydraulic motor, a transmission shaft, a plastic screw, a guide plate, a sleeve which is sleeved on the plastic screw, a plunger rod, a discharging barrel which is sleeved on the plunger rod, and a pressure testing structure, wherein, the actuating motor is connected with the transmission part through the gearing, the transmission part is connected with the ball screw, the ball screw is connected with the ball nut, the oil hydraulic motor is connected with one end of the transmission shaft, the other end of the transmission shaft is connected with the plastic screw, the transmission shaft is fixed with the sleeve together through a base, the sleeve is connected with the discharging barrel through the guide plate, and the ball nut is connected with the tail end of the plunger rod through the pressure testing structure. According to the invention, the plastic structure can be separated from the ejection structure of the injection molding device, and the problems of short service life of traditional screw and nonuniform temperature of the plastic raw material are overcome.

Description

【Technical field】 [0001] The invention relates to a plunger type injection molding device. 【Background technique】 [0002] like figure 1 , the traditional injection molding device includes: a screw 1', a sleeve 2' on the screw, a motor 3', a reduction gear 4', a servo motor 5', a transmission 6', a ball screw 7 ', a ball nut 8', a load sensor 9', the motor 3' drives the rotation of the screw 1' through the reduction gear 4', thereby realizing the plasticization of the raw material by the screw 1', the servo motor 5 ' is connected to the ball screw 7' and the ball nut 8' through the transmission device 6', and the ball nut 8' is connected to the screw 1' through the load sensor 9', so as to realize the injection molding of the raw material by the screw 1'. [0003] However, the screw 1' of the traditional injection molding device plasticizes the raw material and then injects it. The length of the screw 1' is too long. When the raw material is injected, the screw 1' is easil...
