Problems solved by technology

However, due to the high viscosity of such composite materials such as epoxy resin or liquid rubber, and there is air in the material, it is difficult to remove the air mixed in it during casting, resulting in pores in the sample, which will significantly affect the performance tests of the material. accuracy of results
At the same time, the phenomenon of uneven thickness and uneven surface often occurs in the process of material molding, which also causes great errors in the test of material properties.

Abstract

The invention discloses a device and a method for molding a thermoset liquid insulation material by casting. The device comprises a direct-current power supply and a mould used for placing the thermoset liquid insulation material and is characterized by further comprising an electric linear pushing rod, a remote control signal receiver, a bracket upper plate, a bracket lower plate, a clamp, a round roller, a pulling rope, a pulling rope elastic device, a smoothening component and a wireless remote controller. The method comprises operations of fixing the material in the mould, exhausting the air of the material in the mould, smoothing the material in the mould and covering the material in the mould with a film. Through the device and the method, the air mixed in the material can be thoroughly exhausted; meanwhile, the material in the mould is uniform in thickness and smooth in surface; the vacuum film covering operation is completed; due to the vacuum film covering operation, the air can be prevented from being mixed in the material again; the subsequent curing and molding processes are facilitated; the device is simple in structure and convenient to operate.

Description

technical field [0001] The invention provides a thermosetting liquid insulating material pouring molding device and method, which can be applied to the technical field of high voltage and insulation.
