Light plastic well lid processing and forming device and forming method

Abstract

The invention belongs to the technical field of well lid machining, and particularly relates to a light plastic well lid machining forming device and method.The light plastic well lid machining forming device comprises an extrusion device, a sliding inserting opening is formed in the upper portion of an inner cavity of the extrusion device, and well lid feeding devices are symmetrically arranged on the upper portion of the inner cavity of the extrusion device through penetrating inserting openings; the extrusion device comprises an upper fixing box shell, a hydraulic power device is fixedly connected to the middle of an inner cavity of the upper fixing box shell, and a penetrating inserting opening is formed in the lower portion of the inner cavity of the upper fixing box shell. Compared with a common hydraulic machine, the device is characterized in that feeding does not need to be directly carried out in interlayers on the upper side and the lower side of the hydraulic machine, in the well lid pressing process, the device almost does not have too large action when observed from the outside, the device does not need to be opened to carry out material taking work in the material taking process, and the material taking efficiency is greatly improved. And the safety that operators are prevented from being accidentally injured by the hydraulic machine is reflected from each link of pressing, so that the safety and scientificity of production are effectively improved.

Description

A light-weight plastic manhole cover processing and forming device and forming method technical field The invention belongs to the technical field of manhole cover processing, specifically a kind of light-weight plastic manhole cover processing and forming device and components. type method. Background technique With the development of society, more and more cities gradually use plastic composite manhole covers, and this manhole cover adopts unsaturated poly Ester resin-based fiber-reinforced thermosetting composites, also known as bulk molding compounds, are made by compression molding technology. A new type of environmentally friendly cover. The composite manhole cover adopts the high temperature and high pressure one-step molding technology, which has high polymerization degree, high density and good quality. Good impact resistance and tensile strength, with the advantages of wear resistance, corrosion resistance, no rust, no pollution, maintenance-free, etc., an...
