Rubber tube extrusion molding device

Abstract

The invention discloses a rubber tube extrusion molding device. The rubber tube extrusion molding device disclosed by the invention can greatly improve an extrusion molding effect on a rubber tube andensure performance of the rubber tube. According to the rubber tube extrusion molding device disclosed by the invention, vortex is utilized to heat a material at the front end of extrusion molding and keep the material warm, a temperature of a raw material is accurately controlled, and extrusion molding performance is ensured; meanwhile, non-contact heating is utilized by the rubber tube extrusion molding device disclosed by the invention; thus, not only is the volume of an extruded part reduced, but also performance of the raw material is ensured; an overheat effect of contact type heating to a rubber material is avoided. An air blowing structure of an air blowing assembly of the rubber tube extrusion molding device disclosed by the invention is of a reasonable structure, can effectivelyreduce adhesion and can prevent too cold shrinkage; in addition, self-weight downward pressing mode is utilized by the rubber tube extrusion molding device disclosed by the invention to discharge thematerial, so that discharging evenness is ensured, and the problem of pores or too much or too hard discharging is solved.

Description

technical field [0001] The invention relates to a rubber tube extrusion molding device, which belongs to the technical field of rubber tube extrusion molding equipment. Background technique [0002] At present, for the manufacture and molding of rubber tubes, most of them are completed by extrusion molding. The steps are generally to mix the materials for the preparation of rubber tubes, then heat them, and use an open mill to carry out kneading treatment of the rubber materials. Then, the kneaded raw material is sent to an extrusion molding machine for extrusion molding, and the extruded rubber tube is vulcanized if there are requirements for its strength. Among them, the performance of extrusion molding is very important for the preparation of rubber tubes. The quality of the molding is very important to the performance. If the extrusion molding is not good, it is easy to have defects such as bubbles, which will affect the performance of the rubber tube. [0003] The curr...

AI Technical Summary

Problems solved by technology

Among them, the performance of extrusion molding is very important for the preparation of rubber tubes. The quality of the molding is very important to the performance. If the extrusion molding is not good, it is easy to have defects such as bubbles, which will affect the performance of the rubber tube.

[0003] The current extrusion molding of rubber tubes generally only relies on the extrusion molding head for extrusion. During the extrusion process, the temperature and other properties of the rubber are difficult to control. The extruded materials are easy to stick. Pores appear, affecting performance
