Vertical injection molding mechanism achieving efficient mold compounding and working method of vertical injection molding mechanism

Abstract

The invention discloses a vertical injection molding mechanism achieving efficient mold compounding and a working method of the vertical injection molding mechanism. The vertical injection molding mechanism comprises a main box body. A lower supporting plate is fixedly mounted at the bottom of an inner cavity of the main box body. Three longitudinally-arranged guide rods are fixed to the upper endface of the lower supporting plate. The three guide rods penetrate through an injection molding table. A gear disc is rotationally arranged on the lower surface of the injection molding table, and arotating disc is fixedly embedded to the inner ring of the gear disc. Through two symmetrically-arranged second air cylinders and two symmetrically-arranged sliding rods, a hydraulic cylinder and an injection molding pipe are driven to be more balanced in the process of moving downwards; spring rods at the bottoms of sleeves contract when being in contact with the upper surface of an upper supporting plate, and the descending process of the injection molding pipe is buffered; and the technical problems that in the prior art, the vibration amplitude in the injection molding process of an injection molding machine is large, consequently, deviation happens to the injection molding process, the residual rate of injection molding raw materials is large in the prior art, the injection molding raw materials cannot be fully utilized, and meanwhile an injection molding cavity can be possibly jammed are solved.

Description

technical field [0001] The invention relates to the technical field of injection molding, in particular to a vertical injection molding mechanism with high-efficiency mold clamping and a working method thereof. Background technique [0002] Injection molding is a method of producing shapes for industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding molding method and die casting method. According to the arrangement of injection molding device and clamping device, it can be divided into vertical type, horizontal type and vertical-horizontal composite type. [0003] The patent document (201721846392.9) discloses a vertical injection molding machine for multi-color injection molding. The vertical injection molding machine is provided with several injection components on the support frame, and each injection component is equipped with an upper mold steel component. The compo...

Problems solved by technology

[0004] The object of the present invention is to provide a vertical injection molding mechanism with high efficiency mold clamping and its working method, so as to solve the following technical problems: (1) drive the hydraulic cylinder and the injection tube through two symmetrically arranged second air cylinders and two sliding rods The downward movement process is more balanced, and the spring rod at the bottom of the sleeve shrinks when it touches the upper surface of the upper support plate, which buffers the lowering process of the injection tube, and solves the problems caused by the large vibration amplitude of the injection molding machine in the prior art during the injection molding process. The technical problem of deviation; (2) By setting the movable plate in the upper mold cavity, the hydraulic rod pushes the movable plate through the ring clip, the sliding blocks on both sides of the movable plate slide down along the chute, and the movable plate passes the injection molding material through the upper mold Extrusion, after the injection molding is completed, the hydraulic cylinder retracts the hydraulic rod, and the spring pushes the movable plate upward to return to the initial position, which solves the technical problem of high residual rate of injection molding raw materials in the prior art, which cannot be fully utilized, and may cause blockage of the injection molding cavity
