Mold for vertical injection molding machine

Abstract

The invention relates to the technical field of injection molding machines, in particular to a mold for a vertical injection molding machine. The mold comprises a machine base. A lower mold is fixedly connected to the center of the lower side of the inner surface of the machine base, an annular plate is fixedly connected to the upper end of the inner surface of the machine base, and four electric telescopic rods are annularly and fixedly connected to the edge of the lower surface of the annular plate; the lower ends of the four electric telescopic rods are fixedly connected with positioning mechanisms, the inner surfaces of the positioning mechanisms are jointly and fixedly connected with an upper mold, and the center of the lower surface of the upper mold is movably connected with the center of the upper surface of the lower mold through the positioning mechanisms; and each positioning mechanism comprises a lower seat, an upper seat, a first cavity, a first spring and a positioning rod. By arranging the positioning mechanisms, rapid positioning can be achieved in the mold assembly process, the stability of connection between the upper mold and the lower mold can be guaranteed after positioning is completed, the situation that more burrs appear due to mold assembly deviation is avoided, meanwhile, the time consumed for positioning and mold assembly can be shortened, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of injection molding machines, in particular to a mold for a vertical injection molding machine. Background technique [0002] Injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products using plastic molding molds. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it shoot out. To fill the mold cavity, the plastic is first added to the heating barrel of the injection machine, the plastic is heated and melted, and driven by the screw or plunger of the injection machine, it enters the mold cavity through the nozzle and the mold gating system, due to physical and chemical effects And hardening and shaping into injection molded products, thermoplastic injection molding has a short molding cycle, high producti...

[0002] Injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products using plastic molding molds. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it shoot out. To fill the mold cavity, the plastic is first added to the heating barrel of the injection machine, the plastic is heated and melted, and driven by the screw or plunger of the injection machine, it enters the mold cavity through the nozzle and the mold gating system, due to physical and chemical effects And hardening and shaping into injection molded products, thermoplastic injection molding has a short molding cycle, high production efficiency, less wear on the mold by the molten material, and can form large quantities of plastic parts with complex shapes, clear surface patterns and marks, and high dimensional accuracy; but For plastic parts with large wall thickness changes, it is difficult to avoid molding defects;
