Description

Technical Field

[0001] The invention relates to the technical field of rubber moulds, in particular to a rubber mould with a half strip and an ejection structure being synchronized. Background Art

[0002] Rubber molds are mainly used in process environments that require enhanced molding pressure or the transmission of molding pressure. Rubber molds are very useful when it is difficult for vacuum bags to enter the recessed areas of complex mold cavities. For example, when vertical parts on stiffened plates are molded, the expansion of the rubber mold causes the side surfaces of the vertical parts in the part to be subjected to process pressure.

[0003] When the mold is forming, a half bar is used. The half bar and the molding cavity are used to form the mold product. After the product is formed, it is often necessary to eject the material. Since the ejector needs to move upward, a separate transmission device for ejection is often used, such as a cylinder. The ejector pin of the ejector moves upward to demold the material. There are many transmission structures and the manufacturing cost is high. At the same time, the ejector pin cannot be removed for maintenance after long-term use, and the convenience and flexibility of use are poor. Summary of the invention

[0004] The object of the present invention is to provide a rubber mold with a synchronized half bar and an ejection structure, so as to solve the problem that the mold proposed in the above background technology uses a half bar during molding, and utilizes the half bar and a molding cavity to mold a mold product. After the product is molded, it is often necessary to eject the material. Since the ejector needs to move upward, a separate transmission device for ejection is often used, such as a cylinder, and the ejector pin of the ejector moves upward to demold the material. There are many transmission structures used, and the manufacturing cost is high. At the same time, the ejector pin cannot be removed for maintenance after long-term use, and the convenience and flexibility during use are poor.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: a rubber mold with a half strip and an ejection structure synchronized, comprising an upper template, a top wall of the upper template is penetrated with a nozzle, a lower end wall of the upper template is provided with a groove, left and right end walls of the upper template are provided with a clamping groove, a clamping strip is installed on the inner side of the clamping groove, a fixed column is installed on the bottom end side of the clamping strip, a connecting strip is arranged on the side end of the fixed column, a middle column is installed on the end side of the connecting strip, a lower template is installed on the lower end of the upper template, a through opening is penetrated in the middle part of the bottom end wall of the lower template, a sliding groove is formed on the upper end wall of the lower template, a spring column is installed on the inner side of the sliding groove, a slider is installed on the end side of the spring column, a half plate is installed on the top of the slider, a cavity is formed on the upper end wall of the half plate, a guide hole is penetrated on the middle end wall of the half plate, a through hole is penetrated on the left, right and middle end walls of the lower template, and an ejector pin is installed on the inner side of the through hole.

[0006] Preferably, three grooves are provided, and the grooves are equidistantly distributed in the horizontal direction of the upper template.

[0007] Preferably, the upper template is snap-connected with the card strip via a card slot.

[0008] Preferably, the clamping strip is threadedly connected to the fixed column.

[0009] Preferably, the fixed column is fixedly connected to the connecting bar, and the connecting bar is threadedly connected to the middle column.

[0010] Preferably, the number of the fixed columns and connecting bars is twice the number of the middle columns, and the fixed columns and connecting bars are symmetrically distributed about the center of the middle column.

[0011] Preferably, the lower template forms a sliding structure through a sliding groove and a sliding block, and the lower template and the spring column are fixedly connected.

[0012] Preferably, the slider is fixedly connected to the half plates, and three groups of half plates are provided, and each group of half plates has two.

[0013] Preferably, the guide holes and the through holes are movably connected to the ejector pins.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention sleeves the half plates through grooves. When the grooves cover the ends of the half plates downward, the two half plates are brought close to each other. When the two half plates are brought close to each other, the sliders at the bottom of the half plates slide and move along the length direction of the slide grooves, which facilitates the stable displacement of the half plates. When the two half plates are brought close to each other, a cavity is formed, and the cavity is used to mold rubber products.

[0016] 2. The present invention connects the card strip with the card slot, assembles the card strip and the upper template, and the fixed column is threadedly connected to the card strip. When the connecting bar and the middle column rotate, the length of the connecting bar and the middle column is extended or shortened, which is convenient for assembling and disassembling the fixed column and the card strip. At the same time, another fixed column is connected to the ejector pin, so that when the upper template is displaced, the ejector pin is driven to move. After the upper template moves up, the ejector pin moves up to eject the material, which is convenient for synchronous ejection and discharging processing.

[0017] 3. The present invention uses the elastic force of the spring column to bounce the slider, so that the slider slides and moves along the length direction of the slide groove, changes the position of the slider, and the slider drives the half plate to move, allowing the half plate to move outward, which is convenient for the half plate to automatically bounce and discharge the material. At the same time, the guide hole and the perforation are used for sliding and connecting the ejector pin, and the ejector pin moves up to eject the material. BRIEF DESCRIPTION OF THE DRAWINGS
