Description

Technical Field

[0001] The utility model relates to the technical field of forming molds, in particular to a forming mold for a mat. Background Art

[0002] Mats include seat cushions, mattresses, backrest cushions, etc. At present, mats made of polyolefin elastomer (POE) are widely used; among them, polyolefin elastomer (POE) is a thermoplastic elastomer with a relatively low melting point of 50°C - 70°C. The POE material has the dual characteristics of plastic and rubber and has very excellent comprehensive performance.

[0003] Since the melting point of polyolefin elastomer POE is relatively low at 50°C - 70°C, which is lower than the boiling point of water, hot water at a higher temperature can be used to shape the polyolefin elastomer POE. First, the polyolefin elastomer POE (in the shape of a double-sided flat panel) is placed in the mold, and then they are immersed in hot water above its melting point for heating, and then immersed in cold water below its melting point for cooling, and then the mold is opened to obtain seat cushions, mattresses and other mats made of polyolefin elastomer POE in the target shape.

[0004] Therefore, how to provide a forming mold for seat cushions, mattresses and other mats made of polyolefin elastomer POE with a more simplified, efficient and reasonable structure is a technical problem that needs to be urgently solved by those skilled in the art. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a forming mold for a mat made of polyolefin elastomer POE.

[0006] To solve the above technical problems, the technical solution provided by the utility model is as follows:

[0007] A forming mold for a mat includes a mold plate, a lid and an upper spacer frame;

[0008] On the upper length and width surfaces of the mold plate, there are a convex mold in the shape of a protrusion and a concave mold in the shape of a groove for forming the shape of the mat. There are a plurality of vertical through holes vertically penetrating the entire thickness of the mold plate on the mold plate;

[0009] One side of the lid is fixedly arranged at one side of the upper length and width surface of the mold plate through a hinge and bolts. There are a plurality of through holes for water inlet and outlet on the lid;

[0010] The upper spacer frame is arranged at the edge of the upper length and width surface of the mold plate. The upper spacer frame is bolted to the mold plate. The upper spacer frame is an open non-closed frame structure so that one of the partitions at the same position as the hinge is missing, thus not hindering the opening and closing of the lid;

[0011] The lid is provided with a bolt, and a bolt hole is provided on the partition plate in the upper partition frame for the bolt to be inserted into the bolt hole so that the lid can be closed and fixed on the upper partition frame after being closed.

[0012] Preferably, after the lid is closed, the bottom plane of the lid is in flush contact with the top surface of the four peripheral edges of the mold plate.

[0013] The cavity formed by the punch and the die on the mold plate and the bottom plane of the lid is a mold cavity for forming the cushion, and the mold cavity is used for the cushion to be placed horizontally and inversely on the mold plate.

[0014] Preferably, the lid includes a cover plate and a support frame.

[0015] The cover plate is welded to the support frame. A plurality of through holes are provided on the cover plate. The support frame is a lattice frame formed by welding rectangular steel pipes, and the bolt is provided on the rectangular steel pipes in the support frame.

[0016] Preferably, one side of the support frame is fixedly arranged on the cushion pipe through a hinge and bolts. The cushion pipe is connected to one side of the upper length and width surfaces of the mold plate through bolts, and the cushion pipe is clamped between the mold plate and the hinge.

[0017] Preferably, the upper partition frame is used to space apart the two mold plates stacked on top of each other when another molding die is stacked on one molding die.

[0018] The upper partition frame is an open non-closed rectangular frame structure surrounded by three partition plates. The width direction of each partition plate is arranged vertically, and vertical bolts vertically penetrate the width direction of the partition plates and are inserted into the internal thread blind holes on the mold plate to form a bolt connection.

[0019] The present application has achieved the following beneficial technical effects:

[0020] In the present application, the mold plate and the lid form a switchable empty box structure. The cavity formed by the punch and the die on the mold plate and the bottom plane of the lid is a mold cavity for forming the cushion, and the cushion is placed horizontally and inversely in the mold cavity. The mold plate is equipped with all the punches and dies, and the mold cavity is completely located on the mold plate. The lid only covers and closes the mold cavity to prevent the POE material from overflowing, and there is no need for an upper partition plate to participate in forming the mold cavity.

[0021] In the present application, the upper partition frame is used to fix the lid through bolts, space apart the two mold plates stacked on top of each other to facilitate the stacking of multiple molding dies, and the upper partition frame is an open non-closed frame structure with one side missing on all four sides, so that the upper partition frame does not interfere with the opening and closing of the lid.

[0022] In this application, the vertical through holes on the mold plate are used for hot water and cold water to enter and exit the mold cavity, and the through holes on the lid are also used for hot water and cold water to enter and exit the mold cavity.

[0023] In summary, the molding die for cushions, mattresses and other cushions made of polyolefin elastomer POE provided in this application has the advantages of simpler structure, higher efficiency and more reasonable design. Description of the Drawings
