Description

Technical Field

[0001] This utility model relates to the technical field of automatic demolding devices for sealing components, specifically an automatic demolding device for sealing components. Background Technology

[0002] Seal molds are specialized molds used to mold sealing products (such as O-rings, oil seals, gaskets, and skeleton oil seals) made of elastomer materials such as rubber, silicone, and polyurethane. They typically employ compression molding, transfer molding, or injection molding processes. These molds plasticize and vulcanize the raw materials under high temperature and high pressure conditions to obtain dimensionally accurate and stable sealing products.

[0003] After the seal is formed in the mold, it usually needs to be demolded by an additional cylinder or motor drive mechanism. Although the automatic demolding mechanism driven by cylinder or motor can improve production efficiency, it will increase equipment cost and energy consumption. Moreover, the mechanism is complex and inconvenient to maintain. During demolding, if the cylinder or motor drives the ejector pin to rise and is affected by the rise of the upper mold body, it may cause the ejector pin to push the mold cavity area that has not been completely separated prematurely, which may cause interference and mold jamming.

[0004] Therefore, it is necessary to design an automatic demolding device for seals to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic demolding device for sealing components, which solves the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic demolding device for sealing components, comprising an upper mold body and a lower mold body. Two symmetrical positioning pins are fixedly inserted into the top of the upper mold body, and a fixing plate is fixedly connected to the top of each of the two positioning pins. The bottom ends of the two positioning pins are slidably inserted into the interior of the lower mold body. An inlet is provided at the top of the upper mold body. A parting groove is provided at the bottom of the upper mold body and the top of the lower mold body. A sliding groove is provided inside the lower mold body. Two symmetrical limiting blocks are fixedly connected inside the sliding groove. An elastic sliding block is slidably disposed on the top of each of the two limiting blocks. Two symmetrical ejector pins are fixedly connected to the top of each elastic sliding block. Two symmetrical springs are fixedly connected between the top of the inner cavity of the sliding groove and the top of the elastic sliding block. A sliding member is slidably disposed inside the lower mold body, and two symmetrical connecting pins are fixedly connected to the top of the sliding member. The top ends of the two connecting pins are fixedly connected to the bottom of the upper mold body.

[0007] Preferably, the top ends of both ejector pins are slidably inserted into the top of the upper mold body, and the top ends of the two ejector pins are flush with the top of the upper mold body.

[0008] Preferably, one end of each of the two connecting pins is slidably inserted into the interior of the elastic sliding block, and a gap is formed between the sliding member and the elastic sliding block.

[0009] Preferably, the slider and the elastic slider are both X-shaped, and the lengths of the two ends of the slider are less than the lengths of the two ends of the elastic slider, and the two ends of the slider are slidably disposed between the two limiting blocks.

[0010] Preferably, the top of the injection port protrudes outside the upper mold body, and a connecting plate is fixedly sleeved at one end of the injection port outside the upper mold body, and the outer surface of the connecting plate is provided with multiple mounting holes.

[0011] Preferably, the length of the two positioning pins is greater than the length of the two connecting pins, and the two ejector pins and the two springs are respectively located at the top of the four ends of the elastic sliding block.

[0012] The technical solution provided by this utility model has the following advantages compared with the prior art: This invention utilizes a connecting pin and a sliding component. During the lifting and lowering process of the upper mold body, the sliding component moves, and the lifting and lowering of the sliding component pushes an elastic sliding block to gradually raise and lower the ejector pin, thus achieving automatic demolding of the seal. This eliminates the need for external drives such as cylinders or motors, reducing manufacturing costs. Furthermore, the structure is compact and the movements are synchronized. Simultaneously, a lifting difference is reserved between the sliding component and the elastic sliding block, keeping the ejector pin stationary at the initial stage of mold opening. This prevents premature ejection of the seal before complete separation, reducing interference and damage, improving demolding quality, and extending mold lifespan. Attached Figure Description

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0015] Obviously, many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Please see Figure 1-3 This utility model provides an automatic demolding device for sealing components, including an upper mold body 1 and a lower mold body 2. Two symmetrical positioning pins 6 are fixedly inserted into the top of the upper mold body 1, and a fixing piece 5 is fixedly connected to the top of each of the two positioning pins 6. The bottom ends of the two positioning pins 6 are slidably inserted into the interior of the lower mold body 2. An inlet 4 is provided at the top of the upper mold body 1. A parting groove 7 is provided at the bottom of the upper mold body 1 and the top of the lower mold body 2. A sliding groove 14 is provided inside the lower mold body 2. Two symmetrical limiting blocks 13 are fixedly connected inside the sliding groove 14. An elastic sliding block 9 is slidably disposed on the top of the two limiting blocks 13. Two symmetrical ejector pins 8 are fixedly connected to the top of the elastic sliding block 9. Two symmetrical springs 12 are fixedly disposed between the top of the inner cavity of the sliding groove 14 and the top of the elastic sliding block 9. A sliding spring 12 is slidably disposed inside the lower mold body 2. The upper mold body 11 has two symmetrical connecting pins 10 fixedly connected to its top, and the top ends of the two connecting pins 10 are fixedly connected to the bottom of the upper mold body 1. When the upper mold body 1 starts to rise and fall, the two connecting pins 10 will drive the sliding part 11 to rise and fall synchronously inside the sliding part 11. The rising and falling of the sliding part 11 will push the elastic sliding block 9 to rise and fall elastically inside the sliding groove 14. Thus, the rising and falling of the two ejector pins 8 will be used to automatically demold the mold of the sealing part. The demolding work of the entire device can be completed by connecting the connecting plate 3 and the lifting device, which avoids the use of additional cylinders or motors and other driving parts, thus avoiding the increase in cost. At the same time, the difference in rising and falling before the sliding part 11 pushes the elastic sliding block 9 can keep the ejector pin 8 still in the early stage of the upper mold body 1 opening, avoiding the ejector pin 8 from pushing the mold cavity area that has not been completely separated too early, thus preventing interference and mold jamming.

[0017] To facilitate automatic demolding, the top ends of the two ejector pins 8 are slidably inserted into the top of the upper mold body 1, and the top ends of the two ejector pins 8 are flush with the top of the upper mold body 1.

[0018] In order to use the lifting and lowering of the two connecting pins 10 to cooperate with the demolding work of the upper mold body 1 and the lower mold body 2, one end of each of the two connecting pins 10 is slidably inserted into the interior of the elastic sliding block 9, and a gap is formed between the sliding member 11 and the elastic sliding block 9.

[0019] To facilitate the lifting and stabilization of the elastic sliding block 9 and the upper mold body 1, and to use the sliding member 11 to push the elastic sliding block 9 to lift and lower elastically, the shape of the sliding member 11 and the elastic sliding block 9 are both X-shaped, and the length of both ends of the sliding member 11 is less than the length of both ends of the elastic sliding block 9, and the two ends of the sliding member 11 are slidably disposed between the two limiting blocks 13.

[0020] To facilitate connection between the device and the lifting mechanism, the top of the inlet 4 protrudes outside the upper mold body 1, and a connecting plate 3 is fixedly sleeved on one end of the inlet 4 outside the upper mold body 1, and multiple mounting holes are opened on the outer surface of the connecting plate 3.

[0021] Furthermore, in order to position the lifting and sliding of the upper mold body 1, the length of the two positioning pins 6 is greater than the length of the two connecting pins 10, and the two ejector pins 8 and the two springs 12 are respectively located at the top of the four ends of the elastic sliding block 9.

[0022] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0023] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0024] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
