Built-in pipe mould lifting appliance for dismounting extruding machine

Abstract

The invention discloses a built-in pipe mould lifting appliance for dismounting an extruding machine. The built-in pipe mould lifting appliance comprises a rigidity lifting appliance which consists of a lifting ring, angle iron and a bolt, wherein the lifting ring is fixedly arranged on an upper plate surface of the angle iron, a vertical side plate surface is preset with a through hole and process holes according to positions of screw holes in the end surface of the pipe module with different specifications, four process holes are formed in the center of the vertical side plate surface, and the bolt penetrates through the through hole formed in the vertical side plate surface of the angle iron and is connected with an inner pipe module. The built-in pipe mould lifting appliance provided by the invention has the advantages that a worker does not need to directly contact the inner pipe module, the high temperature is resisted when the inner pipe module is changed, the inner pipe module is immediately dismounted, and thus the heat loss is greatly reduced; in addition, the structure is simple, the volume is small, the requirement on the construction space is low, the practical condition on a spot is met, and the built-in pipe mould lifting appliance is beneficial to dismounting operation.

Description

technical field [0001] The invention relates to a plastic equipment accessory, in particular, the invention relates to a hanger for disassembling and assembling the built-in pipe mold of an extruder. Background technique [0002] During the operation of the extruder, the built-in tube mold always maintains the set temperature to ensure that the hot-melt plastic is extruded into the mold cavity to form. Once the product specifications are adjusted during production, the corresponding mold must be replaced. Since the temperature of the pipe mold is as high as 180°C and the location is narrow, workers are not suitable for working in a high temperature environment. And make the workman's hands wear heat-insulating gloves, the operation is also inconvenient, and easily causes the collision accident of inner and outer pipe molds. The usual practice in this industry is to stop production and replace the inner and outer pipe molds after the temperature drops. Although the prior ar...

AI Technical Summary

Problems solved by technology

[0003] The present invention mainly aims at the deficiency that the existing technology cannot replace the inner and outer pipe molds in time, and proposes a lifting tool for disassembling and assembling the built-in tube mold of the extruder under the condition of high temperature at the initial stage of shutdown. Reliable, ensuring that the inner and outer pipe molds do not collide with each other during disassembly and assembly
