Abstract

The invention provides an easily-opened mold for processing cylindrical vulcanized rubber test pieces. When the mold is used, a rubber material is vulcanized by using a flat vulcanizing machine. A cylindrical base and a cylindrical sleeve are placed on the flat vulcanizing machine in a combination mode, a circular mold for processing the cylindrical test pieces is placed into a mold cavity, mixed rubber compounds are added into cylindrical through holes in the circular mold, and then a molding head is placed for heating, pressurizing and vulcanizing. The mold is composed of six parts namely four molds for a vulcanizing process and two devices for drawing after vulcanizing. By virtue of the two devices for drawing after vulcanizing, the problems of high difficulty in drawing, labor consumption in drawing and the like are well solved. Moreover, a disk mold comprising a plurality of small cylindrical holes is designed, so that dozens of cylindrical test pieces can be obtained by vulcanizing at one time; due to the fact that the number is large, later experiments are facilitated. When the mold is used, the whole process is simple; the mold is easy to operate and simple and convenient to open, and the test pieces cannot be damaged.

Description

technical field [0001] The invention relates to an easy-opening mold for processing cylindrical vulcanized rubber test pieces, which belongs to the technical field of molds. Background technique [0002] Rubber is a highly elastic polymer material with reversible deformation, which is widely used in the manufacture of tires, hoses, tapes, cables and other rubber products. The vulcanization of rubber has a great influence on the properties of rubber. The physical properties of over-vulcanized and under-vulcanized rubber parts are very different from those of normal vulcanized rubber parts. Over-vulcanized and under-vulcanized rubber parts will be used in future applications. There may be some problems. Therefore, it is necessary to study the vulcanization of rubber. In the research process, a cylindrical specimen of rubber is needed to test some parameters such as compression set, and this parameter can be used to predict the life of rubber. At present, the mold for rubber...
