Problems solved by technology

[0004] Aiming at the problem that the demoulding process in the prior art is time-consuming, labor-intensive and easily damaged, the invention discloses a vulcanization device, which includes a runner mold for flow diversion and an intermediate mold cavity block for vulcanized products. The cavity movable block includes a number of movable sliders. There are several vulcanization chambers for containing vulcanized products inside the sliders. The products to be vulcanized are set inside the vulcanization chamber.

specific Embodiment 1

[0034] Please refer to figure 1 , a top view of the vulcanization device of the present invention, including an intermediate cavity block 2 for vulcanized products, and the intermediate cavity block 2 is arranged in the middle of the entire device for carrying metal parts that need to be vulcanized and ensuring the vulcanization process . The middle cavity movable block 2 includes several movable sliders and distance limiting elements 24 arranged between the sliders. In this specific embodiment, there are four sliders, and every two adjacent sliders There are two distance-limiting elements 24 between the blocks, and the sliders are movably connected together through the distance-limiting elements 24 to realize rapid separation after vulcanization. The whole separation process is less than 10 seconds, and the vulcanized product No damage and sticking.

[0035] Please refer to image 3 , is a schematic structural diagram of the distance-limiting element 24 of the vulcanizatio...

specific Embodiment 2

[0042] Please refer to Image 6 , a block flow diagram of the demoulding method 8 of the present invention, using the vulcanization device, comprising the following steps:

[0043] S1. After the vulcanization of the product is completed, the runner mold 1 and the support mold 6 are opened.

[0044] First, the runner mold 1 is cooled, and after cooling, it is separated from the lower intermediate cavity block 2, and the rubber in the through hole 11 is separated from the intermediate cavity block 2. After the supporting mold 6 is cooled, since the contact portion 61 is an inclined plane, it can be easily separated by directly moving downward from below. At this time, the runner mold 1 and the supporting mold 6 have been opened.

[0045] S2. Pull the push-pull rod 5 to the outside to drive the movable block 2 in the middle cavity to slide sequentially.

[0046] Further, the push-pull rod 5 pulls the first slider 22 to slide forward, and at this moment, the sliding portion 242 ...

Abstract

The invention relates to a vulcanizing device and a demolding method. The vulcanizing device comprises a channel mold for diversion and an intermediate mold cavity movable block for a vulcanized product. The intermediate mold cavity movable block comprises a plurality of movable sliding blocks and the sliding blocks can be movably connected through a spacing component. In order to realize fast demolding effects, after vulcanization, a push-pull rod is pulled so that the sliding blocks are fast separated and thus fast demolding is realized, demolding efficiency is high and the product is not damaged.

Description

technical field [0001] The invention belongs to the field of rubber vulcanization, in particular to a vulcanization mold and a demoulding method. Background technique [0002] With the development of the rubber product industry, more and more efficiency and low cost are pursued, and the application of multi-cavity vulcanization molds is becoming more and more extensive. The production mode of one mold and multiple cavities greatly improves the utilization rate of vulcanization equipment and improves production efficiency. , and reduce the energy consumption of a single product, thereby reducing production costs. However, during the production process of multi-cavity molds, it still requires a lot of intensive labor to install and demould, which prolongs the operation time, increases the idle time of vulcanization equipment, and increases energy consumption. [0003] The existing demoulding method is to design the mold into upper and lower parts, and a vulcanization cavity i...
