Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of rubber product manufacturing equipment, and in particular relates to an automatic demolding device for rubber products. Background Technology
[0002] like Figure 9 The diagram shown is a structural schematic of one type of rubber product in the prior art. Specifically, the rubber product is a diamond-shaped rubber product, and currently, when producing this diamond-shaped rubber product, it is usually injection molded in an injection molding machine mold.
[0003] Existing injection molding machine molds typically include a front mold, a rear mold, and a mold cavity plate located between the front and rear molds. The specific structure of the mold cavity plate is as follows: Figure 8 As shown, a through hole adapted to the diamond-shaped rubber product is provided on the mold cavity plate. After injection molding, the diamond-shaped rubber product can be located on the mold cavity plate. Then, after separating the front mold and the rear mold, the diamond-shaped rubber product on the mold cavity plate can be demolded.
[0004] However, during the injection molding process, due to the structural characteristics of the product, overflow will occur at specific locations on the front mold and mold cavity plate near the front mold. The existing demolding device only has the function of ejecting the diamond ring rubber product from the mold. Therefore, after demolding, in order to avoid affecting the production quality of the next batch of diamond ring rubber products, the operator needs to wear heat-resistant gloves and manually clean the overflow remaining on the front mold and mold cavity plate one by one. The cleaning efficiency needs to be improved, which will affect the production efficiency of rubber products. Therefore, there are still shortcomings and deficiencies in the existing technology. Utility Model Content
[0005] The purpose of this invention is to provide an automatic demolding device for rubber products to solve the problems mentioned in the background art.
[0006] The technical solution adopted by this utility model to solve the above problems is as follows: An automatic demolding device for rubber products includes a blanking rack. A vertically distributed front mold is installed at one end of the blanking rack, and a support structure that can move along the length of the blanking rack is installed at the other end. A rear mold, opposite to the front mold, is installed on the side of the support structure near the front mold. An electrically operated telescopic structure parallel to the length of the blanking rack is installed between the support structure and the rear mold. The telescopic end of the electrically operated telescopic structure passes through the rear mold and is fitted with a mold cavity plate. An extension frame located above the rear mold is installed on the side of the support structure near the rear mold. The side of the extension frame away from the support structure extends to the outside of the rear mold, and a retractable height adjustment mechanism is installed on the top surface of the extension side of the extension frame. A vertically distributed support plate that can be raised and lowered is installed on the side of the height adjustment mechanism near the front mold. A U-shaped clearance groove with a downward U-shaped opening and opposite to the position of the electrically operated telescopic structure is vertically opened on the support plate. A core demolding structure is installed on the side of the support plate near the front mold. The support plate is also equipped with a shell structure with an open bottom surface that can be covered on the mold cavity plate. The top core demolding structure is installed on the support plate located inside the shell structure. The outer wall of the shell structure away from the support plate is equipped with an opening and closing clamping mechanism, and the inner wall of the shell structure away from the support plate is equipped with a scraping mechanism located at the bottom of the shell structure.
[0007] Furthermore, the core demolding structure includes a mounting base mounted on a support plate, a core being fixedly mounted on the side of the mounting base away from the support plate, and several ejector pins being mounted on the mounting base outside the core, the ejector pins being parallel to the length direction of the blanking frame.
[0008] Furthermore, the side of the top core away from the mounting base is a vertically distributed first inclined surface.
[0009] Furthermore, the support plate is a plate-shaped structure with a cavity, and a cooling mechanism for cooling the top core demolding structure is installed inside the support plate.
[0010] Furthermore, a flow guide box communicating with the interior of the shell structure is installed on the shell structure, and a first inflation connector is connected to the flow guide box.
[0011] Furthermore, the scraping mechanism includes a horizontally arranged support rod, which is perpendicular to the length direction of the blanking frame in the horizontal direction, and a scraping component is installed on the support rod and arranged parallel to the support rod. The scraping component extends out of the support rod on the side near the top core demolding structure.
[0012] Furthermore, the scraper is a plate-shaped structure and is installed on the top surface of the support rod. There is a gap between the side of the scraper away from the top core demolding structure and the inner wall of the shell structure. The top surface of the scraper is a second inclined surface, and the higher side of the second inclined surface is set close to the top core demolding structure.
[0013] Furthermore, the housing structure is connected to a second air inlet connector that is positioned opposite to the scraping mechanism.
[0014] Furthermore, the clamping mechanism includes a clamping cylinder mounted on the housing structure. Two opening and closing grippers are mounted on the side of the clamping cylinder away from the housing structure, and each gripper is equipped with a clamping plate.
[0015] Furthermore, the height adjustment mechanism includes an electric telescopic rod vertically mounted on the extension frame, the telescopic end of which is connected to the support plate.
[0016] The beneficial effects of this utility model by adopting the above technical solution are as follows: This utility model is installed on an injection molding machine mold during use. During the injection molding process, when demolding the diamond-shaped rubber product is required, the front and rear molds are separated. The extension of the telescopic end of the electric telescopic structure moves the mold cavity plate away from the rear mold until it is directly below the housing structure. Then, the height adjustment mechanism lowers the support plate so that the housing structure covers the mold cavity plate. At this point, the mold cavity plate is positioned between the scraping mechanism and the ejector core demolding structure. Before demolding, the support structure moves along the length of the blanking rack, causing the clamping mechanism to approach the front mold to remove any remaining material on the front mold. The remaining overflow material is clamped and cleaned. Then, after the clamping mechanism is moved away from the front mold, the telescopic end of the electric telescopic structure retracts, which can drive the mold cavity plate to gradually approach the support plate. At this time, the diamond-shaped rubber product on the mold cavity plate can be ejected and demolded through the ejector core demolding structure. Then, the telescopic end of the electric telescopic structure extends, which can bring the mold cavity plate against the scraping mechanism. Then, the support plate is driven to rise through the height adjustment mechanism. During the rise of the support plate, the scraping mechanism can scrape off the overflow material remaining on the mold cavity plate. Compared with the existing technology, this can improve the efficiency of cleaning residual overflow material and improve the production efficiency of rubber products. Attached Figure Description

[0019] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0020] like Figures 1 to 7 As shown, this utility model provides an automatic demolding device for rubber products, which can be used to demold such... Figure 9 The diamond-shaped rubber product 16 shown is as follows: Figure 8 Automatic demolding is performed on the mold cavity plate 14 shown; and the present invention includes an electrical control system, which is electrically connected to various electrical components in the present invention to realize automatic demolding operation.
[0021] Specifically, this utility model is installed on an injection molding machine mold during use. The injection molding machine mold includes a blanking rack 9, and a storage basket can be set inside the blanking rack 9 during use. A vertically distributed front mold 10 is installed at one end of the blanking rack 9, and a support structure 11 that can move along the length direction of the blanking rack 9 is installed at the other end of the blanking rack 9. Specifically, an automatic telescopic rod can be installed between the blanking rack 9 and the support structure 11, and slide rails parallel to the length direction of the blanking rack 9 are installed on both sides of the top surface of the blanking rack 9. The support structure 11 is slidably connected to the blanking rack 9 through the slide rails, so that the support structure 11 can move along the length direction of the blanking rack 9 under the action of the automatic telescopic rod. A rear mold 12, which is opposite to the position of the front mold 10, is installed on the side of the support structure 11 near the front mold 10. Furthermore, an electric telescopic structure 13 parallel to the length direction of the blanking rack 9 is installed between the support structure 11 and the rear mold 12. The electric telescopic structure 13 can be configured as an electric push rod or a cylinder, etc. The telescopic end of the electric telescopic structure 13 passes through the rear mold 12 and is fitted with a mold cavity plate 14. Specifically, the front mold 10, the rear mold 12 and the mold cavity plate 14 are adapted to each other. In use, by moving the support structure 11 along the length direction of the blanking rack 9, the rear mold 12, the mold cavity plate 14 and the front mold 10 can be closed. Then, after injection molding is completed, by moving the support structure 11 in the opposite direction along the length direction of the blanking rack 9, the rear mold 12 can be separated from the front mold 10. Then, by extending and retracting the telescopic end of the electric telescopic structure 13, the mold cavity plate 14 can be moved away from or closer to the rear mold 12.
[0022] The specific structure of this utility model installed on the injection molding machine mold is as follows: An extension frame 8 is installed on the side of the support structure 11 near the rear mold 12, located above the rear mold 12. The side of the extension frame 8 away from the support structure 11 extends outside the rear mold 12, and a retractable height adjustment mechanism 6 is installed on the top surface of the extending side of the extension frame 8. A vertically distributed support plate 4 capable of lifting and lowering is installed on the side of the height adjustment mechanism 6 near the front mold 10. Specifically, the height adjustment mechanism 6 includes an electric telescopic rod vertically installed on the extension frame 8, and the telescopic end of the electric telescopic rod is connected to the support plate 4. In use, [the following is a description of the mechanism's operation]... The extension and retraction of the electric telescopic rod can drive the support plate 4 to rise and fall. The support plate 4 has a U-shaped relief groove 41 with a U-shaped opening facing downward and opposite to the position of the electric telescopic structure 13, so as to prevent the electric telescopic structure 13 from affecting the rise and fall of the support plate 4. The support plate 4 is also equipped with a core ejector structure 5 on the side near the front mold 10. Specifically, the number and distribution of the core ejector structures 5 are adapted to the setting method of the through holes 15 on the mold cavity plate 14. In use, the core ejector structure 5 can be used to eject the diamond-shaped rubber product 16 on the mold cavity plate 14 for demolding.
[0023] In addition, a shell structure 1 with a bottom opening and capable of covering the mold cavity plate 14 is installed on the side of the support plate 4 near the front mold 10. The top core demolding structure 5 is installed on the support plate 4 located inside the shell structure 1. A clamping mechanism 3 that can be opened and closed is installed on the outer wall of the shell structure 1 away from the support plate 4. The number and distribution of the clamping mechanisms 3 are adapted to the specific location of residual overflow on the front mold 10. Furthermore, a scraping mechanism 2 is installed on the inner wall of the shell structure 1 away from the support plate 4. The scraping mechanism 2 is located at the bottom of the shell structure 1.
[0024] Specifically, during the injection molding process, when demolding the diamond-shaped rubber product 16 is required, the front mold 10 and the rear mold 12 are separated. The extension of the telescopic end of the electric telescopic structure 13 moves the mold cavity plate 14 away from the rear mold 12 until the mold cavity plate 14 is directly below the shell structure 1. Then, the height adjustment mechanism 6 lowers the support plate 4 so that the shell structure 1 covers the mold cavity plate 14. At this time, the mold cavity plate 14 is located between the scraping mechanism 2 and the core demolding structure 5. Before demolding, the support structure 11 moves along the length of the blanking rack 9, which moves the clamping mechanism 3 closer to the front mold 10 to clamp and clean any remaining overflow on the front mold 10. Then, the clamping mechanism... 3. After moving away from the front mold 10, the retraction end of the electric telescopic structure 13 can drive the mold cavity plate 14 to gradually approach the support plate 4. At this time, the diamond-shaped rubber product 16 on the mold cavity plate 14 can be ejected and demolded through the core demolding structure 5. The demolded diamond-shaped rubber product 16 can fall into the storage basket in the material drop rack 9. Then, the extension end of the electric telescopic structure 13 can be extended to bring the mold cavity plate 14 into contact with the scraping mechanism 2. Then, the support plate 4 is driven to rise through the height adjustment mechanism 6. During the rising process of the support plate 4, the scraping mechanism 2 can scrape off the overflow material remaining on the mold cavity plate 14. Compared with the prior art, this can improve the efficiency of cleaning residual overflow material and improve the production efficiency of rubber products.
[0025] The specific configuration of the core demolding structure 5 is as follows: Figures 5 to 7 As shown, the ejector core demolding structure 5 includes a mounting base 51 mounted on the support plate 4. An ejector core 52 is fixedly mounted on the side of the mounting base 51 away from the support plate 4. The shape of the ejector core 52 is adapted to the shape of the through hole 15 on the mold cavity plate 14. Several ejector pins 53 are also mounted on the mounting base 51 outside the ejector core 52. The ejector pins 53 are parallel to the length direction of the blanking rack 9. Specifically, the number and distribution position of the ejector pins 53 are adapted to the specific position of the overflow on the mold cavity plate 14. In this way, when the diamond-shaped rubber product 16 on the mold cavity plate 14 is ejected and demolded by the ejector core demolding structure 5, the ejector pins 53 can simultaneously eject the overflow on the mold cavity plate 14. At this time, the overflow and the diamond-shaped rubber product 16 can fall together into the storage basket in the blanking rack 9.
[0026] In addition, the shell structure 1 can be slidably connected to the support plate 4, and an automatic telescopic rod can be installed on the support plate 4. The telescopic end of the automatic telescopic rod is connected to the shell structure 1 so that the shell structure 1 can be raised and lowered relative to the support plate 4. After the shell structure 1 is raised, the core demolding structure 5 located inside the shell structure 1 can be exposed to the outside, so as to check from time to time whether there is any overflow material left on the core demolding structure 5 and clean it in time.
[0027] In the existing technology, when the diamond-shaped rubber product 16 is too large, it is easy for the diamond-shaped rubber product 16 to twist and deform and get stuck on the top core 52 when demolding it using the top core demolding structure 5. This makes it difficult for the diamond-shaped rubber product 16 to be removed. Therefore, if... Figures 5 to 7 As shown, the side of the top core 52 away from the mounting base 51 is a vertically distributed first inclined surface 54. Specifically, with Figure 7 As shown, the top core 52 can be set to be thick at the bottom and thin at the top; in this way, when the diamond-shaped rubber product 16 is ejected and demolded using the top core 52, the bottom of the diamond-shaped rubber product 16 can be ejected first, and by setting the first inclined surface 54, the diamond-shaped rubber product 16 can be easily dropped, so as to prevent the diamond-shaped rubber product 16 from being fitted onto the top core 52 when ejected.
[0028] Furthermore, since the injection molding machine mold is usually heated to a certain temperature when injecting rubber products into the mold, the temperature of the ejector core 5 will be relatively high when demolding the diamond-shaped rubber product 16 on the mold cavity plate 14 using the ejector core 5. Therefore, the support plate 4 is a plate-shaped structure with a cavity, and a cooling mechanism for cooling the ejector core 5 is installed inside the support plate 4. Specifically, the support plate 4 is made of thermally conductive material; and the cooling mechanism can be set as a water pipe, which is connected to the cooling source through a water hose. This allows flowing coolant or cold water to be introduced into the support plate 4, and then the ejector core 5 can be cooled through the conduction function of the support plate 4 for easy use.
[0029] Furthermore, such as Figures 1 to 3 and Figure 5 As shown, a flow guide box 7 connected to the inside of the housing structure 1 is installed on the housing structure 1. A first inflation connector is connected to the flow guide box 7. Specifically, the flow guide box 7 can be installed on the top surface of the housing structure 1, and the flow guide box 7 can be connected to an air supply hose through the first inflation connector to connect to the air source. In use, air can be blown into the housing structure 1 through the flow guide box 7 to facilitate the removal of the diamond-shaped rubber product 16 and the overflow material.
[0030] The specific configuration of scraping mechanism 2 is as follows: Figure 5As shown, the scraping mechanism 2 includes a horizontally arranged support rod 21, which is perpendicular to the length direction of the blanking frame 9 in the horizontal direction. A scraping component 22 is installed on the support rod 21 and is parallel to the support rod 21. The scraping component 22 extends beyond the support rod 21 from the side near the top core demolding structure 5. Specifically, the scraping component 22 can be a high-temperature resistant silicone plate with a certain thickness to prevent the overflow material from being too thin and soft. Alternatively, the scraping component 22 can be a high-temperature resistant brush with appropriate thickness and softness to prevent the brush from damaging the diamond-shaped rubber product 16 if it is too hard, or from being too soft to remove the overflow material. In use, the mold cavity plate 14 can be abutted against the side of the scraping component 22 near the top core demolding structure 5 by extending the telescopic end of the electric telescopic structure 13. At this time, as the support plate 4 rises, the scraping component 22 can clean the overflow material remaining on the mold cavity plate 14 from bottom to top.
[0031] Furthermore, such as Figure 5 As shown, the scraper 22 is a plate-shaped structure and is installed on the top surface of the support rod 21. There is a gap between the side of the scraper 22 away from the core demolding structure 5 and the inner wall of the shell structure 1. The top surface of the scraper 22 is a second inclined surface. The higher side of the second inclined surface is set close to the core demolding structure 5. This facilitates the spillage on the scraper 22 to fall off, so as to prevent the spillage from accumulating on the scraper 22.
[0032] Furthermore, the shell structure 1 is connected to a second air inflator, which is opposite to the scraping mechanism 2. Specifically, during use, the air supply hose can be connected through the second air inflator to connect to the air source. Before demolding the diamond-shaped rubber product 16, air can be blown into the shell structure 1 through the second air inflator. The air outlet of the second air inflator is directly opposite the scraping mechanism 2, which makes it easier for the overflow material on the scraping part 22 to fall off. Thus, during the process of closing the front mold 10 and the rear mold 12, the overflow material on the scraping part 22 can be prevented from falling into the mold and affecting the product quality.
[0033] The specific configuration of the clamping mechanism 3 is as follows: Figures 1 to 4 As shown, the clamping mechanism 3 includes a clamping cylinder 31 mounted on the housing structure 1. Two opening and closing grippers 32 are mounted on the side of the clamping cylinder 31 away from the housing structure 1. Each gripper 32 is equipped with a clamping plate 33. Specifically, during use, the clamping cylinder 31 is connected to an air source through an air supply hose. By opening and closing the grippers 32, the clamping plates 33 can be used to clamp and clean the overflow material remaining on the front mold 10. When the grippers 32 are open, the overflow material can fall into the storage basket in the drop rack 9.
[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
