Extrusion device for plastic injection molding based on turbid liquid soft and hard state change

Abstract

The invention relates to an extrusion device for plastic injection molding based on turbid liquid soft and hard state change, and relates to the technical field of plastic injection molding. The device comprises an extrusion cylinder, wherein a push block is movably connected to the inner wall of the right side of the extrusion cylinder, a positive plate is fixedly connected to the inner wall of the top of the push block, a negative plate symmetrical to the positive plate is fixedly connected to the inner wall of the bottom of the push block, and the inner wall of the bottom of the push blockis fixedly connected with a resistor electrically connected with the negative plate. According to the extrusion device for plastic injection molding based on the turbid liquid soft and hard state change, through cooperative use of a dielectric plate and the resistor, the dielectric plate is located at the leftmost end in an initial state, at the moment, a relative area of the positive plate and the negative plate is the largest, a circuit is powered on, a conductive block powers on turbid liquid to be in a solid state, transmission is facilitated, when the dielectric plate is inserted into theinnermost side of the push block, the circuit voltage is reduced to the minimum and is smaller than the minimum path voltage of the resistor, the circuit is disconnected, and deformation and contraction of a rubber ring are facilitated, so that the effect of the controllable turbid liquid state change is achieved.

Description

technical field [0001] The invention relates to the technical field of plastic injection molding, in particular to an extrusion device for plastic injection molding based on the change of soft and hard state of suspension liquid. Background technique [0002] Plastic injection molding is a method of producing industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding and die-casting methods. Injection molding machines use thermoplastics or thermosetting materials. The main molding equipment for plastic products of various shapes, injection molding is achieved through injection molding machines and molds. [0003] The current injection molding machine needs to inject raw materials into the mold through the injection device during use. The current injection device often encounters various problems during use. For example, raw materials are often left at the exit of injection mol...

Problems solved by technology

[0003] The current injection molding machine needs to inject raw materials into the mold through the injection device during use. The current injection device often encounters various problems during use. For example, raw materials are often left at the exit of injection molding, making it difficult to inject. Clean, causing waste of raw materials, affecting the quality of injection molding, and the hardness of these raw materials increases after cooling, easy to block the injection device, affecting later use, requiring regular cleaning, increasing labor intensity, and reducing work efficiency
