[0002] With the continuous improvement of people's living standards, the pursuit of health and comfort is increasing. As a health care device that can relieve fatigue and promote blood circulation, massage chairs are experiencing continuous growth in market demand. The production of massage chairs involves the manufacturing of many parts. Among them, plastic parts are widely used in the structure of massage chairs due to their advantages such as low cost, easy molding, and light weight. However, the production and processing of plastic parts for massage chairs requires the use of mold frames. However, existing mold frames require bolt fixing during use, and the disassembly and assembly process is cumbersome. Furthermore, after the plastic parts are molded, they are not easy to demold. The existing demolding method mainly involves direct pushing with ejector rods, which can easily cause deformation and damage to the plastic parts, affecting product quality. To solve the above problems, a new type of mold frame for processing plastic parts for massage chairs is needed.

[0003] The existing processing mold for plastic parts of massage chairs cannot achieve quick positioning and installation during operation, and cannot avoid the deformation and damage of plastic parts during demolding. Therefore, there is an urgent need for a processing mold for plastic parts of massage chairs. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a processing mold frame for plastic parts of massage chairs, so as to solve the problems that existing processing mold frames for plastic parts of massage chairs cannot be quickly positioned and installed, and cannot avoid deformation and damage of plastic parts during demolding.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a processing mold frame for plastic accessories of a massage chair, comprising a bottom mold, an air valve installed on the outer wall of the bottom mold, an air pipe opened on the inner wall of the bottom mold, a fixing sleeve installed on the inner wall of the bottom mold, a vent hole opened on the side wall of the fixing sleeve, a sealing top rod installed on the inner wall of the fixing sleeve, a return spring installed on the outer wall of the sealing top rod, a mold groove opened on the top of the bottom mold, a positioning plate installed on the top of the bottom mold, a top mold installed on the top of the bottom mold, a positioning groove opened on the inner wall of the top mold, a limit rod installed on the inner wall of the top mold, a limit block installed on the outer wall of the limit rod, and a limit spring installed on the outer wall of the limit rod.

[0006] Preferably, the vent holes are arranged in a circular array with the central axis of the fixed sleeve as the center, and the sealing top rod is engaged with the fixed sleeve.

[0007] Preferably, the sealing top rod forms a telescopic structure with the fixed sleeve via a return spring, and the sealing top rod is movably connected to the bottom mold.

[0008] Preferably, the positioning plate is symmetrically arranged with the central axis of the bottom mold as the center, and the inner wall of the positioning plate is designed with openings.

[0009] Preferably, the positioning plate is inserted into the positioning groove, and the limiting rod is movably connected to the top mold.

[0010] Preferably, the limiting block forms a telescopic structure with the top mold through a limiting spring, and the limiting rod is engaged with the positioning plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the setting of an air valve, air pipe, fixing sleeve, vent hole, sealing ejector rod, return spring and mold groove, allows compressed air to be injected into the air pipe by controlling the air valve after the plastic part is formed. At this time, the sealing ejector rod is lifted by the stroke of the compressed air, and the sealing ejector rod is released from the bottom of the mold groove. The compressed air overflows from around the sealing ejector rod, lifting the formed plastic part. Compared with the traditional demolding method of directly pushing the material with an ejector rod, this utility model demolds by using compressed air, and the plastic part is subjected to more uniform force, avoiding deformation and damage to the plastic part caused by direct pushing of the ejector rod, thereby affecting product quality.

[0013] 2. This utility model, through the setting of a positioning plate, top mold, positioning groove, limiting rod, limiting block, and limiting spring, allows the raw material of the plastic parts to be placed into the mold groove. After that, the limiting block is pushed outward, and then the positioning groove on the inner wall of the top mold is aligned with the positioning plate for insertion. Then the limiting block is released, and the limiting block is pressed inward by the elastic force of the limiting spring, so that the limiting block and the positioning plate are locked together. This allows the bottom mold and the top mold to be quickly positioned and installed. Compared with the traditional bolt fixing method, the fixing method of this utility model is more convenient and stable. Attached Figure Description
