Abstract
Description
Technical Field
[0001] This utility model relates to the field of rubber processing technology, specifically to a quick part removal mold for processing rubber products. Background Technology
[0002] Rubber processing refers to the technological process of turning rubber into rubber products. The basic processes of various rubber product processing include plasticizing, mixing, calendering or extrusion (i.e., extrusion), molding, and vulcanization. Each process has different requirements for the product and is accompanied by several auxiliary operations.
[0003] A search revealed a Chinese patent (CN218906067U) disclosing a mold for processing rubber products. Its key technical features include a mold cavity and a cover plate component. One end of the upper surface of the mold cavity is rotatably connected to an installation component. The cover plate component is perpendicular to the installation component and slidably connected to it. The installation component is equipped with an extrusion component for controlling the movement of the cover plate component. Because the cover plate component is perpendicular to the installation component and slidably connected to it, it moves perpendicularly downwards towards the mold cavity, preventing the rubber liquid from splashing in the same direction. This allows the rubber liquid to flow outwards within the mold cavity, reducing the impact force on the rubber liquid and weakening the impact force of the cover plate component on the rubber liquid. This reduces rubber liquid splashing, minimizes rubber liquid falling onto the ground and production line, and facilitates subsequent cleaning.
[0004] However, the existing technology lacks an automatic demolding mechanism, which makes it easy for the rubber to stick to the mold after solidification, making it difficult to remove the parts quickly and affecting work efficiency. In order to solve the deficiency of the lack of an automatic demolding mechanism in the existing technology, this application uses gears to drive the first rack and the second rack to slide, so that the lower mold and the upper mold move in opposite directions at the same time, thereby positioning the molded workpiece between the bottom pillar and the ejector pin, achieving the effect of separating the mold from the workpiece. Therefore, a new solution is needed to solve this problem. Utility Model Content
[0005] In view of the above-mentioned background technology, there are shortcomings and defects in the existing technology that make it inconvenient to quickly retrieve parts.
[0006] This utility model discloses a quick-release mold for processing rubber products, comprising a base plate, two support plates fixedly connected to the upper surface of the base plate, a lower mold disposed above the base plate, an upper mold disposed above the lower mold, a top rod disposed above the lower mold, a bottom column disposed below the upper mold, a first rack fixedly connected to each side of the lower mold, a second rack fixedly connected to each side of the upper mold, and a groove formed on the outer surface of each support plate, with a gear rotatably connected inside each groove.
[0007] Furthermore, an upper support plate is fixedly connected to the top end of the top rod, and a lower support plate is fixedly connected to the bottom end of the bottom column.
[0008] Furthermore, two drive bars are slidably connected to the upper surface of the base plate, and a support bar is rotatably connected to both ends of each drive bar.
[0009] Furthermore, a motor is fixedly installed on the upper surface of the base plate, and a lead screw is fixedly connected to the output end of the motor.
[0010] Furthermore, four lower positioning blocks are fixedly connected to the outer surface of the lower mold, and four upper positioning blocks are fixedly connected to the outer surface of the upper mold. Each lower positioning block has a positioning rod slidably connected inside.
[0011] Furthermore, the upper surface of the lower mold has two sliding grooves, and the upper surface of the lower mold is provided with a push plate.
[0012] Furthermore, a bearing plate is fixedly connected to the outer surface of the lower mold, and a cylinder is fixedly installed on the upper surface of the bearing plate.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. By setting components such as a first rack and a second rack, this utility model enables the first rack to drive the second rack and the upper mold to move upward through gears when the lower mold moves downward. This achieves the effect of separating the molded workpiece from the upper and lower molds by setting the first rack and the second rack, thus solving the problem of the lack of an automatic demolding mechanism in current technical solutions, which makes it inconvenient to quickly remove parts.
[0015] 2. This utility model, by setting up components such as a push plate and a cylinder, and through the cooperation between the push plate and the cylinder, enables the piston rod of the cylinder to push the push plate to slide through the groove on the upper surface of the lower mold, thereby achieving the effect of pushing the formed workpiece out from between the upper mold and the lower mold by setting up the push plate and the cylinder.

A first rack 7 is fixedly connected to both sides of the lower mold 3, and a second rack 8 is fixedly connected to both sides of the upper mold 4. A groove 9 is formed on the outer surface of each support plate 2, and a gear 10 is rotatably connected inside each groove 9. Corresponding mold grooves are formed in the lower mold 3 and the upper mold 4. The push rod 5 is located inside the mold groove of the upper mold 4 and is slidably connected to the interior of the upper mold 4. The bottom pillar 6 is located inside the mold groove of the lower mold 3 and is slidably connected to the interior of the lower mold 3. An injection hole is provided at the top of the upper mold 4. Both sides of mold 3 and upper mold 4 are slidably connected to the corresponding support plate 2. The first rack 7 and the second rack 8 are slidably connected to the interior of the corresponding groove 9. Each gear 10 meshes with the corresponding first rack 7 and second rack 8. When lower mold 3 slides upward, lower mold 3 drives the first rack 7 to slide upward. The first rack 7 drives the gear 10 to rotate. The gear 10 drives the second rack 8 to slide downward. The second rack 8 drives the upper mold 4 to slide downward, so that lower mold 3 and upper mold 4 are closed. After the rubber solidifies and cools, lower mold 3 is driven to slide downward. Lower mold 3 drives the second rack 8 and upper mold 4 to move upward through the first rack 7 and gear 10, so that the top of bottom pillar 6 is flush with the upper surface of lower mold 3, and the bottom of ejector rod 5 is flush with the lower surface of upper mold 4, so that the formed workpiece is positioned between ejector rod 5 and bottom pillar 6, realizing automatic demolding.
[0025] The top end of the top rod 5 is fixedly connected to the upper support plate 11, and the bottom end of the bottom column 6 is fixedly connected to the lower support plate 12.

[0031] The implementation principle is as follows: Start the motor 15. The output end of the motor 15 drives the lead screw 16 to rotate. The lead screw 16 drives the two drive bars 13 to slide. The two drive bars 13 drive the lower mold 3 to slide upward through the support bar 14. The lower mold 3 drives the first rack 7 to slide upward. The first rack 7 drives the gear 10 to rotate. The gear 10 drives the second rack 8 to slide downward. The second rack 8 drives the upper mold 4 to slide downward, so that the lower mold 3 and the upper mold 4 are in contact. Appropriate rubber is injected into the mold groove of the upper mold 4 through the injection hole. After cooling and solidification, reverse the motor 15. The lead screw 16 drives the drive bars 13 to slide in the opposite direction. The lower mold 3 slides downward and the upper mold 4 slides upward. The workpiece stays between the top rod 5 and the bottom column 6. Start the cylinder 23. The piston rod of the cylinder 23 drives the push plate 21 to slide.
