Description

Technical Field

[0001] This utility model relates to the technical field of gasket forming devices, specifically a gasket forming device for multi-station synchronous stamping. Background Technology

[0002] Rubber gaskets possess properties such as oil resistance, acid and alkali resistance, cold and heat resistance, and aging resistance. They can be directly cut into various shapes of sealing gaskets and are widely used in the pharmaceutical, electronics, chemical, antistatic, flame retardant, and food industries. Hot press molding machines are a type of molding machine suitable for the mixing and batching of polymers such as PVC and masterbatches in the rubber and plastics industries. This allows for testing to ensure the required color and quality are achieved, and can serve as a basis for batching before mass production in factories. The processing method involves placing the plastic or rubber raw material in a mold, clamping it between upper and lower heating plates, and applying pressure under intelligent constant temperature conditions to shape the material. The shaped rubber gaskets are then manually removed and stored. Multi-station synchronous stamping involves having multiple forming cavities in the mold, coupled with multiple stamping heads, allowing multiple gaskets to be formed simultaneously in a single mold.

[0003] In existing multi-station synchronous stamping gasket forming equipment, the entire mold is exposed when heating and forming rubber gaskets. However, the rubber material releases a certain amount of waste gas during the heating process. Large-scale processing will generate a large amount of waste gas, which will directly float in the air and cause serious pollution to the working area environment, damaging human health. Furthermore, when the forming cavity and the stamping head are combined, some stamping heads or forming cavities are aged, resulting in poor sealing. After the rubber melts, it may scatter and splash from the gaps under the pressure, causing the molten rubber material to stick to the worktable, which is not easy to clean.

[0004] Therefore, in view of this, we studied and improved the existing structure to address its shortcomings, and proposed a multi-station synchronous stamping gasket forming device. Utility Model Content

[0005] The purpose of this invention is to provide a multi-station synchronous stamping gasket forming device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-station synchronous stamping gasket forming device, comprising a worktable, an mounting base fixedly installed on the upper surface of the worktable, a cylinder arranged on the upper side of the worktable, a fixing plate fixedly installed on the upper side of the telescopic rod of the cylinder, a spring fixedly connected to the lower surface of the fixing plate, a sealing cover fixedly connected to the lower surface of the spring, a push plate fixedly connected to the bottom end of the telescopic rod of the cylinder, the push plate being disposed inside the sealing cover, and the sealing cover being fitted onto the surface of the telescopic rod of the cylinder, and a purification mechanism being provided on the left side of the upper surface of the sealing cover.

[0007] Preferably, the purification mechanism includes an air cylinder that is fixedly installed through the upper left side of the sealing cover surface, a filter element is fixedly connected to the inner surface of the air cylinder, and an air pump is fixedly connected to the upper end of the air cylinder.

[0008] Preferably, a bracket is fixedly connected to the rear side of the upper surface of the workbench, and the cylinder is fixedly connected to the bracket through it.

[0009] Preferably, a slot is provided in the middle of the upper surface of the mounting base, and a plug is inserted into the inner surface of the slot, and both the slot and the plug are configured as a matching cross shape.

[0010] Preferably, the upper end of the insert is fixedly connected to a mold base, and the upper surface of the mold base is provided with molding cavities evenly distributed.

[0011] Preferably, heating rods are evenly distributed and fixedly connected to the lower surface of the push plate, and the size and position of the heating rods are matched and correspond to those of the molding cavity.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through the arrangement of a fixed plate, spring, and sealing cover, allows the fixed plate to move down synchronously when the cylinder pushes the telescopic rod downwards. The spring then pushes the sealing cover downwards, causing the bottom of the sealing cover to fit against the perimeter of the mounting base, thus covering the entire upper space of the mounting base. The sealing cover contacts the mounting base first, prior to the push plate. As the cylinder continues to extend, the sealing cover is stopped by the mounting base and cannot move further. At this point, the fixed plate can continue to move downwards, causing the spring to compress. The elastic force generated by the spring compression pushes the sealing cover to fit more tightly against the mounting base, thereby sealing the upper space of the mounting base. This prevents the escape of large amounts of waste gas generated during rubber melting during gasket molding and also prevents the softened rubber material from splattering out of gaps during stamping. This not only ensures the stability of the material during rubber gasket stamping but also prevents pollution of the work area caused by waste gas escape.

[0014] 2. This utility model, through the setting of purification mechanism, air cylinder, filter element and air pump, the air pump can suck up the waste gas inside the sealed cover through the air cylinder. After the waste gas is filtered by the filter element, it forms clean air and is discharged. The waste gas is treated in a timely and effective manner, which not only avoids a large amount of waste gas accumulating inside the sealed cover, but also prevents the waste gas from escaping and flying after the sealed cover is opened.

[0015] 3. This utility model, through the setting of slots, inserts, and mold bases, allows the mold base to be quickly connected and assembled with the mounting base after the inserts are inserted into the slots. The cross-shaped inserts and slots ensure that the molding cavity and the heating rod are correctly aligned each time the mold base is installed, avoiding installation misalignment. When demolding the stamped rubber gasket, the mold base can be directly removed for external demolding. At this time, a new mold base can be replaced for the next gasket processing. This ensures that demolding and stamping do not affect each other, and can also improve the overall processing efficiency. External demolding also makes it easier to cool and shape the formed gasket and demold it. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-4 As shown, a multi-station synchronous stamping gasket forming device includes a workbench 1, an mounting base 2 fixedly installed on the upper surface of the workbench 1, a cylinder 3 arranged on the upper side of the workbench 1, a fixing plate 4 fixedly installed on the upper side of the telescopic rod of the cylinder 3, a spring 5 fixedly connected to the lower surface of the fixing plate 4, a sealing cover 6 fixedly connected to the lower surface of the spring 5, a push plate 7 fixedly connected to the bottom end of the telescopic rod of the cylinder 3, the push plate 7 is arranged inside the sealing cover 6, and the sealing cover 6 is sleeved on the surface of the telescopic rod of the cylinder 3. A purification mechanism 8 is arranged on the left side of the upper surface of the sealing cover 6.

[0023] By adopting the above technical solution, when the cylinder 3 pushes the telescopic rod body down, the fixing plate 4 will move down synchronously, and the spring 5 will push the sealing cover 6 down. The bottom of the sealing cover 6 will fit against the four sides of the mounting base 2, thereby covering the entire upper space of the mounting base 2.

[0024] The sealing cover 6 will contact the mounting base 2 first compared to the push plate 7. As the cylinder 3 continues to extend, the sealing cover 6 will be limited by the mounting base 2 and will not be able to move further. At this time, the fixing plate 4 can continue to move down to compress the spring 5. The elastic force generated by the compression of the spring 5 will push the sealing cover 6 to fit more tightly against the mounting base 2, thereby sealing the upper space of the mounting base 2. This can prevent a large amount of waste gas generated by the hot melting of rubber from escaping, and can also prevent the rubber material from softening and being squeezed out of the gap and splashing everywhere during stamping.

[0025] Furthermore, the purification mechanism 8 includes an air cylinder 801 that is fixedly installed through the upper left side of the surface of the sealing cover 6. A filter element 802 is fixedly connected to the inner surface of the air cylinder 801, and an air pump 803 is fixedly connected to the upper end of the air cylinder 801.

[0026] By adopting the above technical solution, the suction machine 803 can suck up the waste gas inside the sealing cover 6 through the air cylinder 801. After the waste gas is filtered by the filter element 802, it forms clean air and is discharged. The waste gas is treated in a timely and effective manner, which not only avoids a large amount of waste gas accumulating inside the sealing cover 6, but also prevents the waste gas from escaping and flying even after the sealing cover 6 is opened.

[0027] Furthermore, a bracket 9 is fixedly connected to the rear side of the upper surface of the workbench 1, and the cylinder 3 is fixedly connected to the bracket 9 through it.

[0028] By adopting the above technical solution, the bracket 9 supports the cylinder 3 and all structural components installed on the lower side of the cylinder 3.

[0029] Furthermore, a slot 10 is provided in the middle of the upper surface of the mounting base 2, and a plug 11 is inserted into the inner surface of the slot 10. Both the slot 10 and the plug 11 are configured as a matching cross shape.

[0030] The upper end of the insert block 11 is fixedly connected to the mold base 12, and the upper surface of the mold base 12 is evenly provided with forming cavities 13.

[0031] Furthermore, heating rods 14 are evenly distributed and fixedly connected to the lower surface of the push plate 7, and the size and position of the heating rods 14 are matched and correspond to those of the molding cavity 13.

[0032] By adopting the above technical solution, the mold base 12 can be quickly connected and assembled with the mounting base 2 after the insert block 11 is inserted into the slot 10;

[0033] The cross-shaped insert 11 and slot 10 ensure that the molding cavity 13 and the heating rod 14 are correctly aligned each time the mold base 12 is installed, thus avoiding installation misalignment.

[0034] When demolding stamped rubber gaskets, the mold base 12 can be directly removed for external demolding. A new mold base 12 can then be replaced for the next gasket processing, ensuring that demolding and stamping do not interfere with each other and improving overall processing efficiency. Working principle: When using this multi-station synchronous stamping gasket forming device, firstly, the mold base 12 is inserted into the slot 10 using the insert block 11, allowing for quick connection and assembly with the mounting base 2. The cross-shaped insert block 11 and slot 10 ensure that the forming cavity 13 aligns correctly with the heating rod 14 each time the mold base 12 is installed. Then, rubber material is added to each forming cavity 13. The cylinder 3 is activated; as the cylinder 3 pushes the telescopic rod downwards, the fixing plate 4 moves downwards simultaneously, and the spring 5 pushes the sealing cover 6 downwards. The bottom end of the sealing cover 6 will fit against the perimeter of the mounting base 2, thus covering the entire upper space of the mounting base 2. The sealing cover 6 will contact the mounting base 2 first, compared to the push plate 7. As the cylinder 3 continues to extend, the sealing cover 6 will be limited by the mounting base 2 and unable to move further. At this time, the fixing plate 4 can continue to move downward, causing the spring 5 to compress. The elastic force generated by the spring 5 will push the sealing cover 6 to fit more tightly against the mounting base 2, thereby sealing the upper space of the mounting base 2. The heating rod 14 will follow the push plate 7 downward and be inserted into the corresponding molding cavity 13. The heating rod 14 first melts the rubber material, and then uses downward pressure in conjunction with the molding cavity 13 to extrude the rubber material into the shape of a gasket. During the melting of the rubber, a certain amount of waste gas is generated. The sealing cover 6 prevents a large amount of waste gas generated by the melting of the rubber from escaping, and also prevents the rubber material from softening and splashing out of the gaps during stamping. Simultaneously, the suction machine 803 can extract the waste gas inside the sealing cover 6 through the air cylinder 801. After being filtered by the filter element 802, the waste gas is discharged as clean air, providing timely and effective treatment of the waste gas. This process not only prevents a large amount of exhaust gas from accumulating inside the sealing cover 6, but also prevents exhaust gas from escaping and flying away after the sealing cover 6 is opened. After the rubber gasket is formed, the mold base 12 can be removed directly for demolding on the outside. At this time, a new mold base 12 can be replaced for the next gasket processing. This ensures that demolding and stamping do not affect each other, and also improves the overall processing efficiency. External demolding also makes it easier to cool and shape the formed gasket and demold it. This is the working principle of the multi-station synchronous stamping gasket forming device.
