Jaw movable motor

Abstract

The invention provides a jaw movable motor, and belongs to the technical field of injection machines. The jaw movable motor solves the problems that a product percent of pass is low, quality is poor and waste materials is more due to poor injection quantity precision of an existing jaw movable motor; according to the technical scheme, the jaw movable motor is installed on a base, comprises a moldclosing mechanism, an injection mechanism and a pre-plasticizing and feeding mechanism, wherein the injection mechanism comprises an injection barrel and an injection oil cylinder; a piston telescopicrod is arranged in the injection barrel, an injection nozzle is arranged at the lower end of the injection barrel, the injection oil cylinder controls the piston telescopic rod to vertically move inthe injection barrel, the pre-plasticizing and feeding mechanism is transversely arranged on the base and can transversely move on the base; and when the pre-plasticizing and feeding mechanism moves below the injection nozzle and is in butt joint with the injection nozzle, a raw material is pressed out by the pre-plasticizing and feeding mechanism, and the piston telescopic rod moves upwards by apreset distance to enable the raw material to be sucked into the injection barrel. According to the jaw movable motor, the precision of injection quantity is improved, the product percent of pass is high, and the quality is good.

Problems solved by technology

[0003] The most common types of injection machines are vertical and horizontal. Vertical injection molding machines and horizontal injection machines have different advantages and disadvantages. According to different needs and different usage occasions, you can choose to use vertical injection molding machines or horizontal injection molding machines. Injection machine, no matter vertical or horizontal, the traditional injection machine components basically include injection system, mold clamping system and hydraulic control system that controls the mold clamping and parting of mold clamping system. The injection system includes injection barrel, plastic or Rubber raw materials are premolded in the injection barrel and then injected into the mold through the injection nozzle of the injection barrel. This kind of injection machine has the following problems in the process of producing plastic or rubber products. The injection volume of raw materials in the injection process cannot be accurately grasped. The raw material is directly injected into the mold from the injection barrel through the rotation of the screw. The raw material in the injection barrel is unknown, but the cavity volume of the mold is fixed, so the volume of the raw material injected into the mold each time cannot be estimated, resulting in injection There is too much or too little raw material in the mold, and the injection accuracy is poor. If too much raw material is injected into the mold, the raw material will flow out from the gap and generate more waste. Therefore, the cleaning frequency of the injection machine is also increased. Moreover, more burrs will be formed on the molded product, requiring secondary treatment, which increases the labor intensity; if the raw material injected into the mold is too small, the qualified rate of the molded product will be greatly reduced, resulting in the integrity and integrity of the molded product Poor, affecting the quality and service life of molded products; and if there are too many waste materials, it will not only pollute the environment, but also increase the production cost, the production efficiency will also decrease, and the production efficiency will decrease
