Plastic pre-extrusion machine die structure and operation method thereof

Abstract

The invention discloses a plastic pre-extrusion machine die structure and an operation method thereof. The plastic pre-extrusion machine die structure comprises an end, a pressing plate, a two-stationnet base, tension columns, a hydraulic oil cylinder base and a hydraulic oil cylinder. The pressing plate is installed at the inner side of a front side plate of a box body. The end is arranged at the outer side of the front side plate of the box body and is parallel to the pressing plate at an interval. The end and the pressing plate are tied through a tie bolt; the two-station net base is inserted into a gap between the end and the pressing plate and can be adjusted in the transverse direction; two installation openings are formed in the plate face of the two-station net base in the transverse direction in a spaced manner; the two tension columns are located at the top and the bottom of the two-station net base respectively; the hydraulic oil cylinder base is connected between the leftends of the two tension columns; and the hydraulic oil cylinder is horizontally connected to the left side face of the hydraulic oil cylinder base, and the hydraulic oil cylinder pushes and pulls thetwo-station net base to move in the transverse direction. The technical problems that the traditional manual die loading and unloading installation efficiency is low, a certain risk exists for the safety of workers, and production accidents are easily caused are solved.

Description

technical field [0001] The invention relates to a plastic pre-extrusion machine mold, in particular to a plastic pre-extrusion machine mold structure and an operation method thereof. Background technique [0002] In the pre-extrusion workshop for the production of denitrification catalyst (selective catalytic reduction), the mold of the pre-extrusion machine is often replaced and cleaned to prevent the dry and hard catalyst mud from blocking the mold. Before changing the mold, you need to remove the pre-extruded end, then lift the end with a lifting chain, use a small spatula to clean the mud between the mold and the end, and then remove the mud on the surface of the mold. Clean, use a flat-head screwdriver to pry off the mold; then put down the lifting chain and fit the end on the machine; when installing the end on the machine, install the top screw by hand first, do not tighten it; then put the new mold on Between the port and the machine, quickly install other screws at...
