Description

Technical Field

[0001] This utility model relates to the field of rubber sealing plug production technology, specifically to a rubber sealing plug ejection and demolding device. Background Technology

[0002] Rubber sealing plugs are round rubber products generally used to prevent leakage, based on the physical properties of natural rubber. Natural rubber has high elasticity and slight plasticity at room temperature, excellent mechanical strength, low hysteresis loss, and low heat generation during repeated deformation, thus exhibiting good flexural resistance. Furthermore, as a non-polar rubber, it has good electrical insulation properties and is widely used.

[0003] In the processing and molding of rubber sealing plugs, a corresponding mold is generally designed and manufactured according to the shape and size of the rubber sealing plug. The rubber strip is placed into one of the mold plates, and the rubber sealing plug is produced by molding through heating and pressing. Then, the rubber sealing plug formed on the other mold plate is taken out. However, in the existing technology, after the rubber sealing plug is pressed on the mold, because the rubber sealing plug is small, the workers need to manually remove the rubber sealing plug one by one with tweezers, which is time-consuming and labor-intensive. Moreover, when removing the rubber sealing plug with tweezers, it is easy to damage the produced rubber sealing plug, affecting the use effect of the subsequent molded sealing plug. Therefore, it is necessary to make improvements. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a rubber sealing plug ejection and demolding device to solve the above problems.

[0012] 1. This rubber sealing plug ejection and demolding device has a mold plate installed inside the operating frame. The two side walls of the mold plate are attached to the inner side wall of the operating frame. The mold plate is clamped and positioned by the operating positioning component against the positioning block, which prevents the mold plate from shifting and shaking during the working process, thus affecting the demolding effect, improving work efficiency and extending the service life of the mold plate. When it is necessary to eject the rubber sealing plug formed on the demolding forming template, the forming template is attached to the opposite side of the mold plate. The forming template is stably installed by the fixing rod. The operator holds the handle of the forming template against the mold plate. The first cylinder pushes the connecting block to drive the ejector plate to move synchronously. The ejector pin of the ejector plate passes through the through hole and pushes the forming template outward. The rubber sealing plug inside the forming template is demolded and left in the slot of the mold plate. The operator can then scrape off the rubber sealing plug on the mold plate. This improves work efficiency and reduces the workload of the operator, while avoiding damage to the rubber sealing plug caused by picking them up one by one with tweezers.

[0013] 2. The second cylinder of the positioning component pushes the mounting rod to move. The mounting rod abuts against the lower side of the movable part and pushes the lower end of the movable part to the left. The movable part uses the fixed shaft as a fulcrum. Under the action of the hinge, the upper end of the movable part moves to the right and tightly abuts against the positioning block, thereby achieving clamping and positioning of the mold plate and avoiding the mold plate from shifting and shaking during the working process, which would affect the demolding effect.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the technical solutions in the specific embodiments of this utility model are clearly and completely described below to further illustrate this utility model. Obviously, the specific embodiments described are only a part of the embodiments of this utility model, and not all of them.

[0025] The following is in conjunction with the appendix Figure 1-6 The present invention will be described in further detail below.

[0026] Example 1:

[0027] A rubber sealing plug ejection and demolding device includes an operating table 1, an operating frame 2 at the upper end of the operating table 1, a mold plate 3 installed inside the operating frame 2, positioning blocks 4 fixedly connected to the left and right sides of the mold plate 3, a positioning component 6 for clamping and positioning the mold plate 3 in conjunction with the positioning blocks 4 on the operating table 1, a first cylinder 5 installed on the operating table 1, a connecting block 7 installed at the output end of the first cylinder 5, a top plug plate 8 installed on the side of the connecting block 7, the top plug plate 8 being located beside the mold plate 3, the mold plate 3 having a through hole 9, a top plug post 10 matching the through hole 9 on the side of the top plug plate 8, and a fixing rod 11 on the outer side of the mold plate 3.

[0028] When using this equipment, the mold plate 3 is installed inside the operating frame 2, with the two side walls of the mold plate 3 fitting against the inner side wall of the operating frame 2. The operating positioning component 6 abuts against the positioning block 4 to clamp and position the mold plate 3, preventing the mold plate 3 from shifting and shaking during operation, which would affect the demolding effect, improve work efficiency, and extend the service life of the mold plate 3. When it is necessary to eject the rubber sealing plug formed on the demolding forming template 17, the forming template 17 is attached to the opposite side of the mold plate 3. The forming template 17 is stably installed by the fixing rod 11. The operator holds the handle of the forming template 17 against the mold plate 3, and the first cylinder 5 pushes the connecting block 7 to drive the top plug plate 8 to move synchronously. The top plug column 10 of the top plug plate 8 passes through the through hole 9 and pushes the forming template 17 outward. The rubber sealing plug in the forming template 17 is demolded and remains in the slot of the mold plate 3. The operator can then scrape off the rubber sealing plug on the mold plate 3 as a whole, which improves work efficiency and reduces the workload of the operator, while avoiding damage to the rubber sealing plug caused by picking them up one by one with tweezers.

[0029] In this embodiment, the positioning component 6 includes a second cylinder 61 disposed at the lower end of the operating table 1. An installation rod 62 is installed at the output end of the second cylinder 61. A first through groove 63 is provided on the operating table 1. A fixing block 65 is fixedly connected to the upper end surface of the operating table 1. A second through groove 64 is provided in the middle of the fixing block 65. The second through groove 64 is located directly above the first through groove 63. A fixing shaft 66 is fixedly disposed in the second through groove 64. A movable part 67 is rotatably disposed on the fixing shaft 66. The upper end of the movable part 67 is located beside the positioning block 4, and the lower end is located beside the installation rod 62.

[0030] When using the positioning component 6, the second cylinder 61 pushes the mounting rod 62 to move. The mounting rod 62 abuts against the lower side of the movable part 67 and pushes the lower end of the movable part 67 to the left. The movable part 67 uses the fixed shaft 66 as a fulcrum. Under the action of the hinge, the upper end of the movable part 67 shifts to the right and tightly abuts against the positioning block 4, thereby achieving clamping and positioning of the mold plate 3 and avoiding the mold plate 3 from shifting and shaking during the working process, which would affect the demolding effect.

[0031] In this embodiment, the positioning block 4 on the left side is provided with a groove 12 that cooperates with the movable part 67. The upper right side of the movable part 67 is embedded in the groove 12 to improve the clamping and positioning effect on the mold plate 3.

[0032] In this embodiment, a fixing post 13 is provided on the side of the mold plate 3. A compression spring 14 is embedded in the fixing post 13. An adjusting bolt 15 is provided on the side of the fixing post 13. One end of the compression spring 14 is connected to the adjusting bolt 15 and the other end is connected to the positioning block 4 located on the right side. There are two compression springs 14 and adjusting bolts 15. Tightening the adjusting bolt 15 adjusts the degree of extension and contraction of the compression spring 14. The compression spring 14 makes the left and right sides of the mold plate 3 reach force balance, thereby improving the stability of the mold plate 3.

[0033] In this embodiment, a collection trough 16 is provided on the upper end of the operating table 1. The collection trough 16 is located inside the operating frame 2. The rubber sealing plug scraped off after demolding falls into the collection trough 16 for collection.

[0034] The working principle of this utility model is as follows: The rubber sealing plug ejects the demolding device. When using this device, the mold plate 3 is installed inside the operating frame 2, and the two side walls of the mold plate 3 are attached to the inner side wall of the operating frame 2. The mold plate 3 is clamped and positioned by the operating positioning component 6 abutting against the positioning block 4, which avoids the mold plate 3 from shifting and shaking during the working process, thus affecting the demolding effect, improving work efficiency and extending the service life of the mold plate 3. Specifically, when using the positioning component 6, the second cylinder 61 pushes the mounting rod 62 to move. The mounting rod 62 abuts against the lower side of the movable part 67 and pushes the lower end of the movable part 67 to shift to the left. The movable part 67, with the fixed shaft 66 as the fulcrum, shifts to the right under the action of the hinge, tightly abutting against the positioning block 4, thereby achieving the clamping and positioning of the mold plate 3 and avoiding the mold plate 3 from shifting and shaking during the working process. When the mold plate 3 shifts and shakes, affecting the demolding effect, and it is necessary to eject the rubber sealing plug formed on the demolding molding template 17, the molding template 17 is placed against the opposite side of the mold plate 3. The molding template 17 is stably installed by the fixing rod 11. The worker holds the handle of the molding template 17 against the mold plate 3. The first cylinder 5 pushes the connecting block 7 to drive the top plug plate 8 to move synchronously. The top plug post 10 of the top plug plate 8 passes through the through hole 9 and pushes the molding template 17 outward. The rubber sealing plug in the molding template 17 is demolded and remains in the slot of the mold plate 3. The worker can then scrape off the rubber sealing plug on the mold plate 3 as a whole. This improves work efficiency and reduces the workload of the worker, while avoiding damage to the rubber sealing plug caused by picking them up one by one with tweezers.

[0035] It should be noted that, depending on the implementation needs, the various components described in the embodiments of this utility model can be divided into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of this utility model. The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be pointed out that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
