A screw-push injection molding machine for metal powder molten material injection

Abstract

The invention provides a screw-push injection molding machine for metal powder melt injection, which includes a control cabinet for controlling the operation of the equipment, an injection molding table, an equipment support, a feeding hopper, a screw pushing mechanism and a wave impact mechanism, and the equipment support is fixed. Installed on the control cabinet, the injection molding station is located at the bottom of the equipment support, involving the field of injection molding machines. The screw push type injection molding machine used for metal powder molten material injection sets a special injection molding structure on the injection molding structure of the vertical screw injection molding machine, and reverses the molten material for many times. The direction enhances the fluidity of the molten material, and at the same time can reduce the output power and energy consumption, thus effectively solving the problem that the metal settlement in the molten material affects the uniformity of the molten material when the general vertical injection molding machine passes through the metal powder molten material. , and ultimately affect the quality of the finished product, and the melt fluidity is poor, the viscosity is high, the output power of injection molding is large, and the energy consumption is high.

Description

technical field [0001] The invention relates to the technical field of injection molding machines, in particular to a screw-push injection molding machine for metal powder molten material injection. Background technique [0002] Injection molding is to use the thermophysical properties of plastics to plasticize, melt and homogenize the material, inject it into the cavity of the mold, and make the finished product after the molten material is kept under pressure, cooled, and solidified through the cavity. In the injection molding process, in order to obtain a high-density, high-strength green body, it is usually necessary to add metal powder to the molten material, but the metal powder molten material formed after the molten material is added with metal powder, compared with the non-metallic additive molten material, the metal powder molten The density of the material increases, the fluidity deteriorates, the viscosity increases, and the metal powder settles in the flowing mo...
