Description

Technical Field

[0001] This invention relates to the field of silicone molding die demolding technology, specifically to a silicone molding die for controlling rapid demolding. Background Technology

[0002] Molds are various shapes and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, a mold is a tool used to create shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly achieves the shaping of objects by changing the physical state of the material being molded. Silicone molding molds primarily utilize vulcanization processes to produce products made of silicone. Medical brushes are one type of product produced by silicone molding molds. Release agents are prohibited in medical products. Steel needles are one of the important components in the production of medical brushes using silicone molding molds.

[0003] In the production of medical brushes using traditional silicone molding molds, the steel needles inside the mold are usually fixed by template extrusion, which has a poor fixing effect. As a result, the steel needles are prone to displacement during the molding process, causing the central column of the product to be misaligned and scrapped, which increases the difficulty of demolding the medical silicone brush.

[0004] Therefore, it is necessary to propose a silicone molding die that can control rapid demolding. Summary of the Invention

[0005] The purpose of this invention is to provide a silicone molding die for controlling rapid demolding, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a silicone molding die for controlling rapid demolding, comprising a lower template, a middle template above the lower template, an upper template above the middle template, two steel pins symmetrically slidably connected to the inner sidewall of the lower template, two fixing blocks symmetrically fixedly connected to one side of the lower template, one end of each of the two fixing blocks being hinged to two connecting pieces via a pivot, a clamping plate fixedly connected to the inner sidewall of each of the two connecting pieces, a connecting plate hinged to the end of each of the two connecting pieces away from the fixing blocks, a steel wire rope fixedly connected to the middle of one side of the connecting plate, a brake handle fixedly connected to one end of the steel wire rope, and one side of the brake handle being installed on the outer sidewall of the lower template.

[0011] A further preferred embodiment: one end of the steel needle body is fixedly connected to a steel needle seat, and the outer side wall of the steel needle seat is slidably connected to the inner side wall of the lower template and the middle template.

[0012] A further preferred embodiment: the upper surface of the lower template is provided with positioning holes evenly distributed, and the lower surface of the upper template is uniformly fixedly connected with positioning posts, the outer sidewall of the positioning post being slidably connected to the inner sidewall of the positioning hole.

[0022] In this embodiment, specifically: two lower mold cavities 104 are symmetrically provided on the upper surface of the middle mold 102, and the inner sidewalls of the two lower mold cavities 104 are uniformly fixedly connected with the material swaying plate 41; the silicone product is shaped through the lower mold cavities 104.

[0023] In this embodiment, specifically: two supports 202 are symmetrically fixedly connected to one side of the lower template 101; the outer wall of the wire rope 206 is slidably connected to the inner wall of the support 202; a spring 42 is fixedly connected to one side of the connecting plate 205; one end of the spring 42 is fixedly connected to the inner wall of the support 202; the moving connecting plate 205 drives the spring 42 to compress the support 202; the compressed spring 42 is used to reset the connecting plate 205.

[0024] In this embodiment, specifically: two limiting rods 43 are symmetrically hinged to the inner sidewall of the lower template 101; a limiting groove 44 is opened on one side of the gate handle 207; the outer sidewall of the limiting rod 43 is slidably connected to the inner sidewall of the limiting groove 44; positioning holes 46 are evenly opened on the upper surface of the lower template 101; positioning posts 47 are evenly fixedly connected to the lower surface of the upper template 103; the outer sidewall of the positioning post 47 is slidably connected to the inner sidewall of the positioning hole 46; the positioning post 47 is slid into the positioning hole 46 by the upper template 103, thereby positioning the lower template 101, the middle template 102, and the upper template 103.

[0025] In this embodiment, specifically: one end of the steel needle body 105 is fixedly connected to a steel needle seat 45, and the outer side wall of the steel needle seat 45 is slidably connected to the inner side wall of the lower template 101 and the middle template 102; the steel needle seat 45 limits one end of the steel needle body 105 so as to straighten and correct the steel needle body 105.

[0026] In this embodiment, specifically: two limiting blocks 48 are symmetrically fixedly connected to the outer side wall of the lower template 101, the outer side wall of the wire rope 206 is slidably connected to the inner side wall of the limiting block 48, and the outer side wall of the wire rope 206 is covered with a conduit 49; the limiting block 48 guides the wire rope 206 and limits the conduit 49, preventing the conduit 49 from moving with the wire rope 206.

[0027] Working principle or structural principle: During use, the moving steel needle seat 45 drives the steel needle body 105 to move. Then, one end of the steel needle body 105 passes through the inner wall of the lower mold cavity 104 and the fixing block 201 in sequence. Then, pressing the brake handle 207 drives the steel wire rope 206 to move. The moving steel wire rope 206 drives the connecting plate 205 to move. The moving connecting plate 205 drives the clamping plate 204 to move through the connecting piece 203. The moving clamping plate 204 fits against the outer wall of the steel needle body 105 and clamps one end of the steel needle body 105. Then, the continuing movement of the connecting piece 203 and the clamping plate 204 straightens and corrects the steel needle body 105. At the same time, the moving connecting plate 205 drives the spring 42 to compress the bracket 202. Then, the moving limit rod 43 slides into the limit groove 44 to limit the brake handle 207, thereby completing the installation and fixation of the steel needle body 105, increasing the stability of the steel needle body 105 and avoiding... To prevent the steel needles from shifting during the silicone molding process, the quality of the product's central pillar is ensured, making the molded silicone brush easier to demold. When producing medical brushes, strips of silicone material are placed on the material placement plate 41, and then the middle template 102 and upper template 103 are moved sequentially to cover the lower template 101. The moving upper template 103 drives the positioning pin 47 to slide into the positioning hole 46, positioning the lower template 101, middle template 102, and upper template 103, thus completing the mold closing process. The mold is then moved to the cleanroom isolation hood machine for production. After the silicone is molded in the mold, the product burrs in the lower mold cavity 104 are squeezed through the middle template 102 and adhered to the bottom of the upper template 103 by the upper template 103. This allows the upper template 103 to remove all the product burrs during the mold opening process, ensuring that the product in the lower mold cavity 104 is burr-free and making demolding easier.
