A high-efficiency vacuum pumping mechanism for a vulcanizing machine

Abstract

Disclosed is an efficient vacuum pumping mechanism of a vulcanizing machine. The efficient vacuum pumping mechanism of the vulcanizing machine comprises a top base, wherein the top base is assembled on supporting columns. Connecting columns are arranged on the top base in a penetrating mode, and a fixed plate is fixedly arranged at the upper ends of the connecting columns. A vacuum cover oil cylinder is arranged above the top base, and the upper end of a piston rod of the vacuum cover oil cylinder is fixedly connected with the top base. A fixed base is arranged at the bottom of the top base, and a piston plate is arranged at the lower end of the fixed base. A heating disc is fixedly arranged on the piston plate, and a vacuum cover frame is arranged below the top base. A sliding plate is arranged at the bottom of the vacuum cover frame, the lower ends of the connecting columns are connected with the vacuum cover frame, and the periphery of the piston plate and the vacuum cover frame are in sealing fit. When the vacuum cover frame descends and is combined with the sliding plate to achieve die assembly, a vacuum chamber is formed in the vacuum cover frame and located between the piston plate and the sliding plate, and the heating disc is located in the vacuum chamber. The vacuum chamber is connected with a vacuum pumping circuit, and the vacuum pumping circuit mainly comprises a vacuum pump and a vacuum storage barrel, wherein the vacuum chamber and the vacuum storage barrel can conduct air convection. The efficient vacuum pumping mechanism of the vulcanizing machine has the advantages that the structure is simple, and the vacuum pumping efficiency can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of vulcanizing machine manufacturing, in particular to a high-efficiency vacuuming mechanism for a vulcanizing machine. Background technique [0002] Generally, the vulcanizing machine is equipped with an upper hot plate and a lower hot plate. During processing, the rubber material is injected into the mold. When the mold moves between the upper hot plate and the lower hot plate, the upper hot plate and the lower hot plate clamp the mold and use The heat generated by the upper heating plate and the lower heating plate heats the rubber material in the mold to melt and form the rubber material. [0003] Now, due to the continuous development of model rubber products, conveyor belts, rubber sheets and synthetic materials, it not only promotes the improvement of the overall level of the flat vulcanizing machine, but also greatly improves its structure. In order to achieve the high quality of rubber products, a ...

Make the production time of the product longer and affect the production efficiency of the product

Moreover, this mechanism has a disadvantage that it takes up a lot of space. The larger the machine panel, the larger the invalid space is, and the slower the vacuuming rate is.

In addition, the vulcanization time of rubber products should not be too long. If the time is too long, it will cause overvulcanization and even cause the products to be scrapped.
