Linkage production line with temperature control heating device

Abstract

The invention provides a linkage production line for injection molding and liquid forming. The linkage production line for injection molding and liquid forming comprises a hard plastic molding device, silicone molding devices, a plurality of movable carriers and a plurality of first heating devices, wherein the hard plastic molding device is provided with hard plastic molding molds; silicone molding devices are provided with silicone molding molds; each movable carrier can be detachably matched with the hard plastic molding molds, and similarly, each movable carrier can be detachably matched with the silicone molding molds; when the movable carriers are installed in the hard plastic molding molds, hard plastic parts can be molded in the movable carrier through the hard plastic molding device, and when the movable carriers are installed in the silicone molding devices, the silicone parts can be molded on the periphery of the hard plastic parts located in the movable carriers through the silicone molding devices to mold the finished products; and each silicone molding device is matched with one first heating device, and the first heating devices are used for heating the movable carriers carrying the hard plastic parts, so that the temperature of the movable carriers carrying the hard plastic parts reaches the operating temperature of the silicone molding molds.

Description

technical field [0001] The invention relates to the fields of plastic molding and liquid silicone molding, in particular to a linkage production line with a temperature-controlled heating device. Background technique [0002] Some plastic products are composed of interconnected hard rubber parts and silicone parts. The production process requires injection molding of the hard rubber part, and then secondary molding of the silicone part on the basis of the hard rubber part to form a complete plastic. Composite products. Because the molding temperature of the hard rubber material and the liquid silicone material are inconsistent, the molding temperature of the hard rubber part of the plastic product is higher than that of the silicone part. Due to the temperature difference between injection molding and silicone molding, it is difficult to coordinate the two links; in addition, the temperature difference is likely to cause problems such as product flash and dimensional variat...

AI Technical Summary

Problems solved by technology

[0003] In view of the deficiencies of the prior art, the purpose of the present invention is to provide a linkage production line with a temperature-controlled heating device, which can avoid problems such as product overflow and dimensional variation caused by temperature differences between injection molding and liquid silicone molding
