Description

Technical Field

[0001] The utility model relates to the technical field of rubber molds, in particular to a rubber mold with synchronous huff bars and ejection structure. Background Technique

[0002] Rubber molds are mainly used in process environments that require enhanced forming pressure or transfer of forming pressure. They are very useful when it is difficult for a vacuum bag to enter the recessed area of a complex mold cavity. For example, when forming vertical parts on a stiffener plate, the expansion of the rubber mold causes the sides of the vertical parts in the workpiece to be subjected to process pressure.

[0003] When the mold is forming, huff bars are used. The huff bars and the forming cavity are used to form the mold product. After the product is formed, it is often necessary to eject the material. Since the ejection requires upward movement, a separate driving device for ejection, such as a cylinder, is often used to push the ejector pin for ejection upward to demold the material. There are many matching transmission structures, resulting in high manufacturing costs. At the same time, the ejector pin cannot be disassembled for maintenance after long-term use, and the convenience and flexibility during use are relatively poor. Content of the Utility Model

[0004] The purpose of the utility model is to provide a rubber mold with synchronous huff bars and ejection structure to solve the problems mentioned in the above background technique. When the mold is forming, huff bars are used. The huff bars and the forming cavity are used to form the mold product. After the product is formed, it is often necessary to eject the material. Since the ejection requires upward movement, a separate driving device for ejection, such as a cylinder, is often used to push the ejector pin for ejection upward to demold the material. There are many matching transmission structures, resulting in high manufacturing costs. At the same time, the ejector pin cannot be disassembled for maintenance after long-term use, and the convenience and flexibility during use are relatively poor.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A rubber mold with synchronous huff bars and ejection structure, including an upper template. A nozzle is penetrated through the top wall of the upper template. A groove is opened on the lower end wall of the upper template. Card slots are opened on the left and right end walls of the upper template. A card strip is installed inside the card slot. A fixed column is installed on the bottom side of the card strip. A connecting strip is arranged on the side of the fixed column. A middle column is installed on the side end of the connecting strip.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. In the present utility model, the half-mold plates are sleeved through the grooves. When the grooves are covered downward on the end sides of the half-mold plates, the two half-mold plates approach each other. When the two half-mold plates approach each other, the sliders at the bottoms of the half-mold plates slide and displace along the length direction of the sliding grooves, facilitating the stable displacement of the half-mold plates. When the two half-mold plates approach each other, a cavity is formed, and the cavity is used for molding rubber products.

[0016] 2. In the present utility model, the upper template is snap-connected to the clamping strip through the clamping groove to assemble the clamping strip and the upper template. The fixed column is threadedly connected to the clamping strip to assemble the fixed column and the clamping strip. When the connecting strip and the middle column rotate, the lengths of the connecting strip and the middle column are extended or shortened, facilitating the assembly and disassembly of the fixed column and the clamping strip. At the same time, another fixed column is assembled with the ejector pin. When the upper template displaces, the ejector pin is driven to displace. After the upper template moves upward, the ejector pin moves upward to push the material, facilitating the synchronous material pushing and discharging process.

[0017] 3. In the present utility model, the slider is elastically moved by the elastic force of the spring column, so that the slider slides and displaces along the length direction of the sliding groove, changing the position of the slider. The slider drives the half-mold plate to displace, causing the half-mold plate to move outward, facilitating the automatic elastic movement of the half-mold plate for discharging. At the same time, the guide holes and the perforations are used for slidingly connecting the ejector pins, and the ejector pins move upward to push the material for discharging.
