Description

Technical Field

[0001] This utility model relates to the field of liquid injection mold technology, specifically a heat insulation mold. Background Technology

[0002] In modern manufacturing, LIM (Liquid Injection Molding) technology is widely used in the production of silicone products due to its advantages such as high production efficiency and good product molding quality. The core principle of this technology is to inject liquid silicone raw material into a mold cavity with a specific structure, and then heat the mold to cause the liquid silicone inside the cavity to undergo a cross-linking and curing reaction at a high temperature, thereby forming a solid silicone product that conforms to the shape of the mold cavity.

[0003] In the actual production process of LIM (Liquid Injection Molding) molds, in order to ensure that the liquid silicone can fully cure and achieve the required physical and mechanical properties of the product, the mold usually needs to be heated to a high temperature, generally between 120℃ and 200℃. This high temperature condition is crucial to ensuring that the liquid silicone completes the curing reaction and directly affects the quality of the final product.

[0004] However, when the silicone product has cured inside the mold and needs to be removed, the mold itself remains at a high temperature. Operators inevitably approach or even come into contact with these hot parts of the mold during removal, significantly increasing the risk of burns. Such burns not only harm the operator's health and affect their work performance, but may also lead to improper handling during removal due to fear of burns, affecting efficiency and potentially damaging the molded product.

[0005] To reduce the risk of burns to operators when retrieving parts and to ensure efficiency and product integrity, we propose a heat-insulating mold. Utility Model Content

[0019] 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.

[0020] Please see Figure 1-6 This utility model provides a technical solution: a heat insulation mold, including a workbench 1, a lower mold base 3 slidably mounted on the top of the workbench 1, a number of modules 23 fixedly connected to the top of the lower mold base 3, two lower templates 14 slidably connected to the top of the lower mold base 3, a cavity formed between the lower templates 14 and the modules 23, an injection component for injecting liquid silicone into the cavity is installed on the workbench 1, and a part removal component for easy removal of the product is installed on the workbench 1; The component removal assembly includes a mounting platform 19, which is fixedly connected to the bottom of the inner cavity of the lower mold base 3. Several sets of springs 20 are fixedly connected to the top of the mounting platform 19. A lifting plate 25 is fixedly connected to the top of the springs 20. Several sets of lifting rods 24 are fixedly connected to the top of the lifting plate 25. The lifting rods 24 slide through the module 23. A stripping template 22 is fixedly connected to the top of the lifting rods 24. A groove matching the stripping template 22 is provided on the module 23. A pressure block 21 is fixedly connected to the top of the lifting plate 25. The pressure block 21 slides out of the lower mold base 3. A moving mechanism that drives the lower mold base 3 to move is installed on the worktable 1. A sliding mechanism that drives the lower template 14 to slide is installed on the lower mold base 3.

[0021] In use, the lower template 14 and module 23 are heated to a certain temperature by an external heating component. Then, the injection assembly presses down the pressure block 21, which drives the lifting plate 25, lifting rod 24, and ejector plate 22 to descend, so that the ejector plate 22 is located in the groove on the module 23. Then, liquid silicone is injected into the cavity between the lower template 14 and module 23. The liquid silicone undergoes a cross-linking and curing reaction at high temperature to form a solid silicone product with the same shape as the cavity. After the product is formed, the injection assembly no longer restricts the pressure block 21. Under the elastic force of the spring 20, the ejector plate 22 rises, lifting the product so that the product is initially separated from the cavity, making it easier for the operator to pick up. The moving mechanism drives the lower mold base 3 to move. At the same time, under the action of the sliding mechanism, both sets of lower templates 14 move away from the module 23, thereby expanding the operating space for the operator to pick up the product, making it easier for the operator to pick up the product safely and efficiently, thereby reducing the risk of burns when the operator picks up the product, and ensuring the efficiency of picking up the product and the integrity of the product.

[0022] The moving mechanism includes an electric push rod 12, which is fixedly installed on the inner wall of the worktable 1. A connecting plate 16 is fixedly connected to the bottom of the lower mold base 3. A first sliding opening matching the connecting plate 16 is opened on the worktable 1. The connecting plate 16 is slidably connected to the first sliding opening. The output end of the electric push rod 12 is fixedly connected to the connecting plate 16.

[0023] The electric push rod 12 is activated, which moves the connecting plate 16 and the lower mold base 3.

[0024] The sliding mechanism includes two sets of screws 18, which are rotatably mounted on the lower mold base 3. The screws 18 are threaded with mounting blocks 27. The bottom of the lower mold plate 14 is fixedly connected to two sets of sliding blocks 26. The lower mold base 3 has a second sliding opening that matches the sliding blocks 26. The sliding blocks 26 are slidably connected to the second sliding opening. The bottom of the sliding blocks 26 is hinged to a connecting rod 17. The end of the connecting rod 17 away from the sliding blocks 26 is hinged to the mounting block 27. A rotating mechanism that drives the screws 18 to rotate is installed on the worktable 1.

[0025] The rotating mechanism includes two sets of racks 11, which are fixedly connected to the top of the inner cavity of the worktable 1. The worktable 1 has two sets of third sliding mouths that match the screw 18. The screw 18 is movably connected to the third sliding mouths. A gear 15 is fixedly connected to the bottom of the screw 18, and the gear 15 meshes with the rack 11.

[0026] The movement of the lower mold base 3 drives the screw 18 to move, which in turn drives the gear 15 to move. Under the action of the rack 11, the gear 15 rotates, which in turn drives the screw 18 to rotate, causing the mounting block 27 to move upward. Through the connecting rod 17, the sliding blocks 26 move away from each other, causing the lower template 14 to move away from the module 23.

[0027] The injection assembly includes several sets of support rods 2, which are fixedly connected to the top of the worktable 1. A top plate 5 is fixedly connected to the top of the support rods 2, and a cylinder 6 is fixedly installed on the top of the top plate 5. The output end of the cylinder 6 is fixedly connected to the upper mold base 4. The upper mold base 4 is slidably sleeved on the outside of the support rods 2. An upper template 9 is fixedly connected to the bottom of the upper mold base 4. The upper template 9 matches the lower template 14. Several sets of injection tubes 8 are fixedly inserted on the upper mold base 4, and several sets of first flow channels connected to the injection tubes 8 are opened on the upper template 9.

[0028] The bottom of the upper template 9 is fixedly connected to a heat insulation plate 10. The heat insulation plate 10 has several sets of communication ports that are connected to the first flow channel. The heat insulation plate 10 is made of fiber-reinforced composite material with carbon fiber as the reinforcing skeleton and high-temperature resistant resin.

[0029] The cylinder 6 is activated to lower the upper mold base 4, which in turn lowers the upper mold plate 9 and the heat insulation plate 10. During this process, the pressure block 21 is squeezed and moves downward until the bottom of the heat insulation plate 10 abuts against the top of the lower mold plate 14. Then, the liquid silicone is injected into the cavity through the injection tube 8, the first flow channel and the connecting port by external power. Under the action of the heat insulation plate 10, the high temperature of the lower mold plate 14 will not be transferred to the upper mold plate 9, so that the temperature in the first flow channel can be kept at a low level, which can prevent the liquid silicone from solidifying in the first flow channel.

[0030] The lower template 14 is fixedly fitted with an insulation cover 13, which contains fiberglass wool. This reduces heat loss from the lower template 14, lowers energy consumption, and further prevents operators from being burned by the lower template 14.

[0031] Several sets of casters 7 are fixedly installed at the bottom of the workbench 1, and a controller is set on the front side of the workbench 1. This facilitates moving it to a suitable position.

[0032] A support cover 28 is fixedly connected to the top of the mounting platform 19. The support cover 28 is slidably sleeved on the outside of the lifting plate 25, and the top of the support cover 28 is fixedly connected to the top of the inner cavity of the lower mold base 3. This enhances the overall strength of the lower mold base 3 while protecting the spring 20.

[0033] Working principle: In use, the lower mold plate 14 and module 23 are first heated to a certain temperature by an external heating component; then, the cylinder 6 is activated to drive the upper mold base 4 down along the support rod 2, which in turn drives the upper mold plate 9 and the heat insulation plate 10 down. During this process, the pressure block 21 is squeezed and moves downward, driving the lifting plate 25, the lifting rod 24 and the ejector plate 22 down until the bottom of the heat insulation plate 10 abuts against the top of the lower mold plate 14. At this time, the ejector plate 22 is located in the groove on the module 23; then, the liquid silicone is injected into the cavity between the lower mold plate 14 and the module 23 by external power through the injection tube 8, the first flow channel on the upper mold plate 9 and the connecting port on the heat insulation plate 10. The liquid silicone undergoes a cross-linking and curing reaction at high temperature to form a solid silicone product. At the same time, under the action of the heat insulation plate 10, the high temperature of the lower mold plate 14 will not be transferred to the upper mold plate 9, preventing the liquid silicone from curing in the first flow channel; after the product is formed, the cylinder 6 drives... The upper mold base 4, upper template 9, and heat insulation plate 10 rise. The heat insulation plate 10 no longer restricts the pressure block 21. Under the elastic force of the spring 20, the lifting plate 25, lifting rod 24, and ejector plate 22 rise, lifting the product so that it initially separates from the cavity. Then, the electric push rod 12 is activated to drive the connecting plate 16 to move along the first sliding opening on the worktable 1, thereby driving the lower mold base 3 to move. When the lower mold base 3 moves, it drives the screw 18 to move, causing the gear 15 at the bottom of the screw 18 to rotate under the action of the rack 11, which in turn drives the screw 18 to rotate. The rotation of the screw 18 causes the mounting block 27 to move upward. Through the connecting rod 17, it drives the sliding block 26 to move along the second sliding opening on the lower mold base 3 in a direction away from each other. Finally, it drives the two sets of lower templates 14 to move away from the module 23, expanding the operating space and making it easier for operators to safely and efficiently pick up the product. This reduces the risk of burns when operators pick up the product and ensures the efficiency of picking up the product and the integrity of the product.
