Description

Technical Field

[0001] The present invention relates to the technical field of plastic molding, and more particularly to a plastic mold with a rapid cooling function. Background Art

[0002] Plastic is a material composed of inorganic and organic elements. Plastic is molten at high temperatures and solid at low temperatures. In the existing production process of plastic products, two molds (a movable mold and a fixed mold) are generally put together and molten plastic is injected into the gap between them. After cooling and shaping, the desired plastic product is formed.

[0003] Since plastics are usually injected in a molten state, the temperature of the plastics is relatively high during the molding process. However, the commonly used plastic molds do not have a rapid cooling function, and often have to wait for the plastics to cool naturally. However, the natural cooling molding speed of plastics is slow, which is not convenient for rapid demolding, seriously affecting the production efficiency of plastic products.

[0004] In view of the above problems, some solutions are also provided in the prior art. For example, Chinese utility model patent with announcement number CN214353991U discloses a plastic mold with a rapid cooling function. The device controls the refrigeration pipe through a refrigerator to quickly cool down the lower mold body, thereby promoting rapid molding of the mold and improving production efficiency. Although the prior art can improve production efficiency to a certain extent, the prior art cools down the plastic mold through a refrigeration pipe, and the contact area between the refrigeration pipe and the plastic mold is limited, so that the cooling effect of the plastic mold is relatively slow, which still affects the production efficiency of the plastic product. Summary of the invention

[0005] In view of the problems existing in the prior art, the object of the present invention is to provide a plastic mold with a rapid cooling function, which can improve the production efficiency of plastic products.

[0006] To solve the above problems, the present invention adopts the following technical solutions.

[0007] A plastic mold with a rapid cooling function comprises a workbench, a fixed mold is fixedly mounted on the top wall of the workbench, a movable mold is provided on the workbench to cooperate with the fixed mold, and a moving component for driving the movable mold to move is provided on the top wall of the workbench; The cooling component includes a cooling groove opened on the movable mold, an air inlet pipe and an exhaust pipe are respectively inserted on the side walls of the cooling groove, a refrigerator whose input end is connected to the exhaust pipe is installed on the top wall of the workbench, an air pump whose output end is connected to the exhaust pipe is installed on the top wall of the workbench, and the input end of the air pump is connected to the output end of the refrigerator, a mounting plate is horizontally slidably installed in the cooling groove, and a sealing plate for sealing the air inlet pipe and the exhaust pipe is symmetrically installed on the top wall of the mounting plate.

[0008] Furthermore, a first spring is commonly installed between the top wall of the mounting plate and the cooling groove, and a memory alloy wire is commonly installed between the top wall of the mounting plate and the cooling groove, a first elastic rod is evenly fixedly installed on the top wall of the cooling groove, a vertical rod is evenly fixedly installed on the top wall of the mounting plate, and a first inclined block is fixedly installed on the bottom wall of the first elastic rod, a push block cooperating with the first inclined block is fixedly installed on the top wall of the vertical rod, and a cooling assembly is provided on the fixed mold.

[0009] Furthermore, second elastic rods are evenly fixedly installed on the side walls of the cooling tank, and second inclined blocks are evenly fixedly installed on the blocking plate.

[0010] Furthermore, a vertical groove is provided on the fixed mold, a push plate is slidably installed in the vertical groove, an electric push rod with an output end fixedly connected to the push plate is installed on the workbench, and a switch electrically connected to the electric push rod is provided in the cooling groove.

[0011] Furthermore, a cavity is formed on the push plate, air holes are evenly formed on the cavity, a vertical groove connected to the cavity is formed on the electric push rod, and a horizontal groove connected to the vertical groove is formed on the fixed mold.

[0012] Furthermore, the moving assembly includes a mounting frame fixedly mounted on the top wall of the workbench, a hydraulic rod with an output end fixedly connected to the movable mold is mounted on the mounting frame, and the hydraulic rod is electrically connected to the electric push rod.

[0013] Furthermore, a heat preservation sleeve is installed between the mounting plate and the cooling tank, and the memory alloy wire is located in the heat preservation sleeve, and the memory alloy wire is symmetrically arranged around the electric push rod.

[0014] Furthermore, the fixed die is provided with a heat conducting rod in contact with the memory alloy wire.

[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) This scheme provides a cooling groove. When the air flows through the cooling groove, the heat of the plastic can be driven to flow to the outside. The cooling groove can increase the contact area between the cold air and the fixed mold, so that the heat of the plastic in the mold cavity can be quickly transferred to the cold air, thereby achieving rapid cooling of the plastic in the mold cavity and allowing the plastic in the mold cavity to be quickly cooled and formed, thereby improving the production efficiency of plastic products. (2) In this solution, by setting the first elastic rod and the second elastic rod, when the mounting plate drives the blocking plate to move downward, the first elastic rod and the second elastic rod can be driven to vibrate, and then the first elastic rod and the second elastic rod transmit the vibration to the inner wall of the fixed mold, vibrating the molten plastic in the mold cavity and improving the density of the plastic product, effectively preventing the presence of a large number of pores on the surface of the plastic product, which requires remelting and rework, and further improving the production efficiency of the plastic product; (3) In this solution, the first elastic rod cooperates with the second elastic rod. When the mounting plate moves upward, the mounting plate drives the first elastic rod to vibrate again through the vertical rod and the push block. At the same time, when the mounting plate moves upward, the second elastic rod is driven to vibrate again through the second inclined block. Then, during the vibration of the first elastic rod and the second elastic rod, the vibration can be transmitted to the inner wall of the fixed mold, causing the inner wall of the fixed mold to vibrate. By vibrating the inner wall of the fixed mold, the plastic product after molding can be prevented from being closely attached to the inner wall of the fixed mold and generating negative pressure adsorption, which results in a longer time to remove the plastic product, thereby further improving the production efficiency of plastic products. (4) This solution sets a push plate. When the push plate drives the plastic product to move upward, the push plate drives the air holes to contact the gap between the plastic product and the inner wall of the fixed mold. Then, the external airflow can flow into the cavity through the horizontal grooves and the vertical grooves, and flow into the gap between the plastic product and the inner wall of the fixed mold through the air holes on the cavity, thereby further avoiding negative pressure adsorption between the plastic product and the inner wall of the fixed mold. At the same time, when the inner wall of the fixed mold shakes, the airflow can quickly diffuse in the gap between the inner wall of the fixed mold and the plastic product, further improving the demoulding efficiency and further improving the production efficiency of plastic products.

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0019] See also Figures 1 to 8 A plastic mold with a rapid cooling function comprises a workbench 1, a fixed mold 2 is fixedly mounted on the top wall of the workbench 1, and a movable mold 3 cooperating with the fixed mold 2 is provided on the workbench 1, a moving component 8 for driving the movable mold 3 to move is provided on the top wall of the workbench 1, and a cooling component 4 is provided on the fixed mold 2; The cooling component 4 includes a cooling groove opened on the movable mold 3, and an air inlet pipe 401 and an exhaust pipe 402 are respectively inserted on the side walls of the cooling groove, a refrigerator 403 whose input end is connected to the exhaust pipe 402 is installed on the top wall of the workbench 1, and an air pump 404 whose output end is connected to the exhaust pipe 402 is installed on the top wall of the workbench 1, and the input end of the air pump 404 is connected to the output end of the refrigerator 403, a mounting plate 405 is horizontally slidably installed in the cooling groove, and a blocking plate 406 for blocking the air inlet pipe 401 and the exhaust pipe 402 is symmetrically installed on the top wall of the mounting plate 405, a first spring 407 is commonly installed between the top wall of the mounting plate 405 and the cooling groove, and a memory alloy wire 408 is commonly installed between the top wall of the mounting plate 405 and the cooling groove.

[0020] A first elastic rod 501 is evenly fixedly installed on the top wall of the cooling tank, a vertical rod 502 is evenly fixedly installed on the top wall of the mounting plate 405, and a first inclined block 503 is fixedly installed on the bottom wall of the first elastic rod 501, a push block 504 cooperating with the first inclined block 503 is fixedly installed on the top wall of the vertical rod 502, and a moving component 8 for driving the movable mold 3 to move is provided on the top wall of the workbench 1.

[0021] The second elastic rods 505 are evenly fixedly installed on the side wall of the cooling tank, and the second inclined blocks 506 are evenly fixedly installed on the blocking plate 406 .

[0022] In the initial state, the first spring 407 is in a compressed state. When in use, the movable mold 3 and the fixed mold 2 are covered by the moving assembly 8, and then the plastic is introduced into the mold cavity of the movable mold 3 and the fixed mold 2 through the injection tube on the fixed mold 2. As the plastic enters the mold cavity, the temperature of the mold cavity gradually increases. After the temperature of the mold cavity increases, the heat is transferred to the cooling tank through the fixed mold 2. At the same time, the temperature in the mold cavity is transferred to the memory alloy wire 408, and the memory alloy wire 408 is heated and stretched. At this time, the first spring 407 stretches and drives the mounting plate 405 to move downward, and drives the blocking plate 406 to move downward during the downward movement of the mounting plate 405, and then gradually moves the blocking plate 406 downward during the downward movement of the blocking plate 406. Gradually, it loses contact with the air inlet pipe 401 and the exhaust pipe 402. At this time, the air flow flows to the air inlet pipe 401 through the air pump 404, and flows to the cooling tank through the air inlet pipe 401. Then the air flow drives the heat in the cooling tank to flow to the exhaust pipe 402, and then the air flow with heat will flow to the refrigerator 403 through the exhaust pipe 402, and after being cooled by the refrigerator 403, it flows to the air pump 404, and then flows to the cooling tank again. That is, by setting the cooling tank, the contact area between the cold air and the fixed mold 2 can be increased, so that the heat of the plastic in the mold cavity can be quickly transferred to the cold air, and then the plastic in the mold cavity can be quickly cooled, and the plastic in the mold cavity can be quickly cooled and formed, which plays a role in improving the production efficiency of plastic products.

[0023] In the process of the first spring 407 driving the mounting plate 405 to move downward, the mounting plate 405 drives the push block 504 to move downward through the vertical rod 502, and in the process of the push block 504 moving downward, a thrust is applied to the first inclined block 503, and then the first inclined block 503 drives the first elastic rod 501 to deform under the action of the thrust, and after the push block 504 is out of contact with the first inclined block 503, the first elastic rod 501 is reset and shaken under the action of its own elastic force, and then the first elastic rod 501 can transmit the vibration to the inner bottom wall of the fixed mold 2, so that the molten plastic in the mold cavity can be vibrated and the density of the plastic product can be improved, effectively preventing the presence of a large number of pores 605 on the surface of the plastic product, which requires re-melting and rework, and further improving the production efficiency of the plastic product.

[0024] In the process of the mounting plate 405 moving downward, the blocking plate 406 is driven to move downward, and in the process of the blocking plate 406 moving downward, the second inclined block 506 is driven to move downward, and then in the process of the second inclined block 506 moving downward, it will hit the second elastic rod 505, and cause the second elastic rod 505 to deform, and after the second inclined block 506 is out of contact with the second elastic rod 505, the second elastic rod 505 is reset and shakes, and then in the process of the second elastic rod 505 shaking, the vibration can be transmitted to the inner wall of the fixed mold 2, and the molten plastic in the mold cavity can be vibrated, thereby further improving the density of the plastic product.

[0025] When the mounting plate 405 moves upward, the mounting plate 405 drives the first elastic rod 501 to vibrate again through the vertical rod 502 and the push block 504. At the same time, when the mounting plate 405 moves upward, the second elastic rod 505 is driven to vibrate again through the second inclined block 506. Then, during the shaking of the first elastic rod 501 and the second elastic rod 505, the vibration can be transmitted to the inner wall of the fixed mold 2, and the inner wall of the fixed mold 2 can be vibrated. By vibrating the inner wall of the fixed mold 2, the plastic product after molding is prevented from being closely attached to the inner wall of the fixed mold 2 and generating negative pressure, which results in a longer time to remove the plastic product, thereby further improving the production efficiency of plastic products.

[0026] like Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a vertical groove 606 is provided on the fixed mold 2, a push plate 601 is slidably installed in the vertical groove 606, an electric push rod 602 whose output end is fixedly connected to the push plate 601 is installed on the workbench 1, and a switch 603 electrically connected to the electric push rod 602 is provided in the cooling tank.

[0027] The push plate 601 is provided with a cavity 604 , and the cavity 604 is evenly provided with air holes 605 . The electric push rod 602 is provided with a vertical groove 606 connected with the cavity 604 , and the fixed mold 2 is provided with a horizontal groove 607 connected with the vertical groove 606 .

[0028] By adopting the above technical solution, after the plastic product is cooled and formed, as the mounting plate 405 moves upward, the mounting plate 405 gradually contacts the switch 603, and after the first inclined block 503 and the second inclined block 506 drive the first elastic rod 501 and the second elastic rod 505 to shake respectively, the switch 603 is triggered, and the output end of the electric push rod 602 is extended. In the process of the extension of the output end of the electric push rod 602, the push plate 601 can be driven to move upward, and the molded plastic product is driven to move upward in the process of the push plate 601 moving upward. At the same time, in the process of the push plate 601 pushing the plastic product upward, the first elastic rod 501 and the second elastic rod 505 drive the inner wall of the fixed mold 2 to vibrate, which can avoid negative pressure adsorption between the plastic product and the fixed mold 2, resulting in damage to the plastic product when taking out the plastic product, and the need for rework, thereby further improving the production efficiency of plastic products.

[0029] In the process of the push plate 601 driving the plastic product to move upward, the push plate 601 drives the air hole 605 to contact the gap between the plastic product and the inner wall of the fixed mold 2. Then, the external airflow can flow into the cavity 604 through the horizontal groove 607 and the vertical groove 606, and flow into the gap between the plastic product and the inner wall of the fixed mold 2 through the air hole 605 on the cavity 604, thereby further avoiding negative pressure adsorption between the plastic product and the inner wall of the fixed mold 2. At the same time, in the process of the shaking of the inner wall of the fixed mold 2, the airflow can quickly diffuse in the gap between the inner wall of the fixed mold 2 and the plastic product, further improving the demolding efficiency, and further improving the production efficiency of plastic products.

[0030] like Figure 2 As shown, the moving assembly 8 includes a mounting frame 801 fixedly mounted on the top wall of the workbench 1 , and a hydraulic rod 802 whose output end is fixedly connected to the movable mold 3 is mounted on the mounting frame 801 , and the hydraulic rod 802 is electrically connected to the electric push rod 602 .

[0031] By adopting the above technical solution, when the movable mold 3 needs to be covered with the fixed mold 2, the user can control the output end of the hydraulic rod 802 to extend and drive the movable mold 3 downward to cover the fixed mold 2. At the same time, during the extension of the output end of the hydraulic rod 802, the output end of the electric push rod 602 contracts and drives the push plate 601 to reset. Then, when the output end of the electric push rod 602 extends and drives the push plate 601 to move upward, the output end of the hydraulic rod 802 contracts and drives the movable mold 3 to move upward.

[0032] like Figure 4 As shown, a heat preservation sleeve 9 is installed between the installation plate 405 and the cooling tank, and the memory alloy wire 408 is located in the heat preservation sleeve 9 , and the memory alloy wire 408 is symmetrically arranged around the electric push rod 602 .

[0033] By adopting the above technical solution and setting the insulation sleeve 9, it is possible to prevent the cold air from affecting the normal extension of the memory alloy wire 408 when passing through the cooling tank, and by symmetrically setting the memory alloy wire 408 around the electric push rod 602, it is possible to prevent the mounting plate 405 from being stuck due to uneven force when the memory alloy wire 408 contracts and drives the mounting plate 405 to move upward, thereby ensuring the normal upward movement of the mounting plate 405.

[0034] like Figure 4 As shown, the fixed die 2 is provided with a heat conducting rod 10 in contact with the memory alloy wire 408 .

[0035] By adopting the above technical solution and providing the heat conducting rod 10, the temperature of the plastic in the mold cavity can be quickly transferred to the memory alloy wire 408, thereby ensuring that the memory alloy wire 408 can quickly expand and contract according to the temperature of the plastic.

[0036] Instructions for use: When in use, the movable mold 3 and the fixed mold 2 are covered by the movable assembly 8, and then the plastic is introduced into the mold cavity of the movable mold 3 and the fixed mold 2 through the injection tube on the fixed mold 2, and as the plastic enters the mold cavity, the temperature of the mold cavity gradually increases, and after the temperature of the mold cavity increases, the heat will be transferred to the cooling tank through the fixed mold 2, and at the same time, the temperature in the mold cavity is transferred to the memory alloy wire 408, and the memory alloy wire 408 is heated and stretched, at this time, the first spring 407 stretches and drives the mounting plate 405 to move downward, and in the process of the mounting plate 405 moving downward, it drives the blocking plate 406 to move downward, and then in the process of the blocking plate 406 moving downward, it gradually disconnects from the intake pipe 401 and the exhaust pipe 402. 402, and then the airflow drives the heat in the cooling tank to flow to the exhaust pipe 402. Then the airflow with heat flows to the refrigerator 403 through the exhaust pipe 402, and flows to the air pump 404 after being cooled by the refrigerator 403, and then flows to the cooling tank again. That is, by setting the cooling tank, the contact area between the cold air and the fixed mold 2 can be increased, so that the heat of the plastic in the mold cavity can be quickly transferred to the cold air, and then the plastic in the mold cavity can be quickly cooled. Under the action of the thrust, the first inclined block 503 drives the first elastic rod 501 to deform, and after the push block 504 is out of contact with the first inclined block 503, the first elastic rod 501 is deformed. The rod 501 is reset and shaken under the action of its own elastic force, and then the first elastic rod 501 can transmit the vibration to the inner bottom wall of the fixed mold 2, so that the molten plastic in the mold cavity can be vibrated; when the mounting plate 405 moves upward, the mounting plate 405 drives the first elastic rod 501 to shake again through the vertical rod 502 and the push block 504. At the same time, when the mounting plate 405 moves upward, the second elastic rod 505 is driven to shake again through the second inclined block 506. Then, during the shaking of the first elastic rod 501 and the second elastic rod 505, the vibration can be transmitted to the inner wall of the fixed mold 2, and the inner wall of the fixed mold 2 can be shaken. By vibrating the inner wall of the fixed mold 2, the molding can be avoided. The plastic product is tightly attached to the inner wall of the fixed mold 2 and negative pressure occurs, so it takes a long time to remove the plastic product. In the process of the push plate 601 driving the plastic product to move upward, the push plate 601 drives the air hole 605 to contact the gap between the plastic product and the inner wall of the fixed mold 2. Then, the external airflow can flow into the cavity 604 through the horizontal groove 607 and the vertical groove 606, and flow into the gap between the plastic product and the inner wall of the fixed mold 2 through the air hole 605 on the cavity 604, thereby further avoiding the negative pressure adsorption of the plastic product and the inner wall of the fixed mold 2. At the same time, in the process of the shaking of the inner wall of the fixed mold 2, the airflow can quickly diffuse in the gap between the inner wall of the fixed mold 2 and the plastic product, further improving the demolding efficiency.

[0037] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
