Crank arm type up-moving all-electric injection molding machine

Abstract

The invention discloses a crank arm type up-moving all-electric injection molding machine. The injection molding machine is a vertical injection molding machine and comprises a moving mold plate, a fixed mold plate, a piece conveying disc, a base and multiple pull rods; the fixed mold plate is positioned at the lower end of the moving mold plate; the piece conveying disc is arranged on the fixed mold plate, the piece conveying disc comprises a working part corresponding to the moving mold plate and a preparation part staggered with the moving mold plate, and the working part and the preparation part can be driven by a first power mechanism to exchange positions mutually; the base is positioned at the lower end of the fixed mold plate; and one end of each pull rod is fixed to the moving mold plate, the other end of each pull rod is fixed to the base, the middle of each pull rod penetrates through the fixed mold plate, and the pull rods can be driven by a second power mechanism to do displacement in the vertical direction. According to the injection molding machine, an upper mold plate is designed as the moving mold plate, so that inaccurate mechanical arm positioning caused by displacement of the lower mold plate is avoided, and the double-station piece conveying disc is arranged at the lower mold plate, so that the efficiency of the injection molding machine is improved.

Description

technical field [0001] The invention relates to the technical field of injection molding machines, in particular to a crank-arm type upward-moving all-electric injection molding machine. Background technique [0002] Injection molding machine is also known as injection molding machine or injection machine. It is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products using plastic molding molds. Divided into vertical, horizontal, all-electric. The injection molding machine heats the plastic, applies high pressure to the molten plastic, and makes it shoot out to fill the mold cavity. [0003] First of all, most of the existing vertical injection molding machines use the hydraulic type, that is, the hydraulic mechanism is used to provide power for the mold opening and closing actions, so that the operation accuracy is not high, and some manual intervention is required, which is inconvenient to use.

AI Technical Summary

Problems solved by technology

[0003] First of all, most of the existing vertical injection molding machines use the hydraulic type, that is, the hydraulic mechanism is used to provide power for the mold opening and closing actions, so that the operation accuracy is not high, and some manual intervention is required, which is inconvenient to use. At the same time, the hydraulic type Injection molding machines waste energy, and have serious pollution, loud noise, and slow speed;

[0004] Furthermore, during the injection molding process, the injection molding machine needs to complete the mold opening action, mold closing action, injection molding action, and removal of injection molded parts. There are also some products, such as inserts, which need to be placed in the injection cavity first. In the middle, the injection molding step is completed, which leads to the injection molding machine needing to wait for the injection molded product to be removed after the injection molding of a product, and to place the next insert in the injection cavity, which is in an idle state, resulting in the efficiency of the injection molding machine low;

[0005] In addition, in order to achieve more intelligence and automation, the existing injection molding machines often cooperate with the mechanical arm to complete the actions of inserting inserts and taking out products. In order to cooperate with the equipment, the mechanical arm needs to be fixed on the lower template. However, the lower The template needs to complete the action of mold opening and closing, which causes the mechanical arm to move along with the lower template, which affects the positioning accuracy and service life of the robotic arm

[0006] Based on the above, the present invention discloses a crank-arm type upward-moving all-electric injection molding machine, which is used to solve the defects of high energy consumption, slow speed, low efficiency, serious pollution, and unfavorable automation process in existing vertical injection molding machines.
