Efficient die changing trolley and die changing method

Abstract

The invention relates to the field of extrusion blow molding dies, in particular to an efficient die changing trolley and a die changing method. The efficient die changing trolley and the die changingmethod involve a roller conveying belt assembly, a die locking assembly and a die changing trolley assembly, wherein the roller conveying belt assembly is used for placing and conveying dies, the roller conveying belt assembly is slidably connected with the die changing trolley assembly through a sliding rail, the mold locking assembly is fixedly installed at the bottom of the roller conveying belt assembly, a mold locking piece can pop up to the positions among rollers of the roller conveying belt assembly to lock the dies, a height adjusting device and trundles are arranged on the die changing trolley assembly, and the die changing trolley assembly can drive the roller conveying belt assembly to move and adjust the height of the dies placed on the roller conveying belt assembly, Die moving is carried out by moving the die changing trolley assembly, the die changing efficiency can be improved, and the safety and the stability in a die changing process can be improved by moving and locking the roller conveying belt assembly.

Description

technical field [0001] The invention relates to the field of extrusion blow molding moulds, in particular to an efficient mold changing trolley and a mold changing method. Background technique [0002] Extrusion blow molding is a method of making hollow thermoplastic parts. Well-known blow molding objects include bottles, barrels, cans, boxes, and all containers for packaging food, beverages, cosmetics, medicines, and daily necessities. Large blow molded containers are often used for packaging of chemical products, lubricants and bulk materials. [0003] In the existing technology, the replacement of molds in the extrusion blow molding industry is generally carried out by crane hoisting, but in the actual use process, many product factories cannot hoist the mold from the top due to the height of the machine itself or the height of its own factory building. Higher-end fields such as medicine and food products require dust-free workshops with suspended ceilings. Without driv...

Problems solved by technology

[0003] In the existing technology, the replacement of molds in the extrusion blow molding industry generally uses crane hoisting, but in the actual use process, many product factories cannot hoist the mold from the top due to the height of the machine itself or the height of its own factory building. Higher-end fields such as medicine and food products require dust-free workshops with suspended ceilings. Without driving, changing molds has become a major pain point for product factories. It is time-consuming, labor-intensive, and inefficient. Workers use simple handling tools to change molds. Security Risk
