PE hollow wall pipe injection mold heating assembly

Abstract

The invention relates to the field of injection mold heating assemblies, in particular to a PE hollow wall pipe injection mold heating assembly. The PE hollow wall pipe injection mold heating assemblycomprises a limiting structure, a storage structure, a fixing structure, a driving structure, a heating ring, a clamping structure and a winding structure; the two ends of the heating ring of an annular structure used for heating the mold are connected to the clamping structure, and the clamping structure used for fixing the heating ring is rotationally connected with the fixing structure; the driving structure is arranged in the fixing structure, and the driving structure is connected to the clamping structure, so that the clamping structure is conveniently driven to be opened through the driving structure, then the two ends of the heating ring are conveniently fixed to the clamping structure, the distance between the heating ring and an extruder is increased, and scalding caused by accidental touching of the extruder is effectively prevented; and meanwhile, the clamping structure is conveniently driven by the driving structure to drive the heating ring to wrap the end part of the extruder, so that the heating ring is conveniently bent and shaped, the contact effect of the heating ring and the extruder is better, and the heating ring is more convenient and quicker to mount and dismount.

Description

technical field [0001] The invention relates to the field of injection mold heating components, in particular to an injection mold heating component of a PE hollow wall pipe. Background technique [0002] The extruder of PE hollow-wall pipe is a tool for producing plastic products; it is also a tool for giving plastic products a complete structure and precise dimensions. Injection molding is a processing method used in mass production of certain complex-shaped parts. The heated and melted plastic is injected into the mold cavity by high pressure from the injection molding machine, and after cooling and solidification, the molded product is obtained. Before the plastic product is formed, it needs to be plasticized in the plasticizing extruder of the PE hollow wall tube, and then extruded and cooled. , in the production process of PE winding pipe, the raw material is plasticized by the extruder, and then it is preliminarily shaped by the die of the plasticized extruder, and th...

Problems solved by technology

[0003] However, most of the heating rings used in the plasticizing extruder of the traditional winding tube are connected by bolts or bound into a ring with iron wires, so that the heating ring is sleeved at the end of the extruder, and the heating ring is connected to the end of the extruder. The contact of the heating ring is poor, which affects the heating and heat preservation effect. At the same time, it is necessary to use auxiliary components such as pliers to bend the heating ring into a fixed shape during the installation and disassembly process. The operation flexibility is poor, and it is easy to touch the extruder by mistake and cause burns. First, the length of the wire is too long during use, which affects cleanliness, and the operator is likely to cause the wire to fall off during the operation of the machine, resulting in poor stability
