A thermoplastic molding equipment based on the principle of electroluminescence

Abstract

The invention relates to the technical field of plastic molding, and discloses a thermoplastic molding equipment based on the principle of electroluminescence, including a support frame, an extruding plate is movably connected inside the support frame, and a bottom plate is movably connected to the lower part of the extruding plate , the upper part of the extrusion plate is movably connected with the inner top wall of the support frame through a spring, the interior of the extrusion plate is fixedly connected with an electro-optic mechanism, the surface of the bottom plate is provided with an injection channel, the electro-optic mechanism includes a shell, and the interior of the shell is fixedly connected with a Light-emitting tube, according to the thermal effect of current: when the conductor is energized, it will generate heat, and the law of converting electric energy into heat energy by conducting current is quantitatively explained. Since the electrode mechanism is arranged on the surface of the extruded plate, the heat generated by the current is directly transferred to the surface of the extruded plate, increasing the temperature on the surface of the extruded plate, reducing the temperature difference between the extruded plate and the molten material, thereby achieving The outer layer in contact with the cavity surface will not have the effect of a solid shell.

Description

technical field [0001] The invention relates to the technical field of plastic molding, in particular to a thermoplastic molding equipment based on the principle of electroluminescence. Background technique [0002] Plastic is a high molecular compound polymerized by addition polymerization or polycondensation reaction with monomer as raw material. It has medium resistance to deformation and is between fiber and rubber. Agents, colorants and other additives. [0003] Among them, plastic molding is an essential step in the production of plastic materials. According to the characteristics of plastic parts, when the molten material contacts the outer layer of the cavity surface, it cools immediately to form a low-density solid shell, and due to the poor thermal conductivity of plastic, the plastic The inner layer of the part is cooled slowly to form a high-density solid layer with large shrinkage, resulting in wall thickness, slow cooling, and high-density layer thickness, whi...

[0003] Among them, plastic molding is an essential step in the production of plastic materials. According to the characteristics of plastic parts, when the molten material contacts the outer layer of the cavity surface, it cools immediately to form a low-density solid shell, and due to the poor thermal conductivity of plastic, the plastic The inner layer of the part is cooled slowly to form a high-density solid layer with large shrinkage, resulting in wall thickness, slow cooling, and high-density layer thickness, which finally leads to large shrinkage and deformation of molded plastic products, and injection-molded items cannot achieve the desired shape. , so a thermoplastic molding equipment based on the principle of electroluminescence came into being
