Description

Technical Field

[0001] This utility model relates to the field of molds, and in particular to a molding mold for rubber shock-absorbing pads. Background Technology

[0002] In industrial production, rubber vibration damping pads are widely used in various industries such as automotive, machinery, and construction due to their excellent elasticity, wear resistance, and vibration damping and noise reduction performance. Injection molds are the core equipment for achieving mass production and high efficiency of rubber vibration damping pads. Currently, injection molds for rubber vibration damping pads typically consist of a lower mold, an upper mold, and a mold cavity. During production, molten rubber raw material is injected into the mold cavity. After the raw material cools and solidifies within the mold cavity, the finished product is removed through mold opening. With the increasing market demand for rubber vibration damping pads and the gradual improvement in product precision requirements, the structural design and production efficiency of injection molds are receiving increasing attention. Among these, the cooling system, as a key component of the mold, directly affects the production quality and processing cycle of rubber vibration damping pads.

[0003] In the process of producing rubber shock absorbers using injection molds, the cooling rate plays a crucial role. On one hand, the cooling rate directly affects the molding quality of the rubber shock absorbers: if the cooling rate is too slow, the molten rubber remains at a high temperature in the mold cavity for an extended period, easily leading to defects such as uneven shrinkage, surface depressions, and internal air bubbles, resulting in decreased product dimensional accuracy and failure to meet assembly and usage requirements. On the other hand, the cooling rate is closely related to production efficiency: a slow cooling process prolongs the processing cycle of individual products, reducing the mold's output per unit time and making it difficult to meet the needs of large-scale mass production. Therefore, this application proposes a molding die for rubber shock absorbers with a fast cooling rate. Utility Model Content

[0004] The main objective of this invention is to provide a molding die for rubber shock-absorbing pads, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A molding die for a rubber shock-absorbing pad includes a lower die and an upper die. A water-cooling pipe and an air-cooling assembly are fixedly installed inside the lower die and around its cavity. The water-cooling pipe is fixedly installed inside the air-cooling assembly and is connected to a cooling water circulation device. The water-cooling pipe consists of a cooling water pipe and inlet / outlet water pipes. There are two inlet / outlet water pipes, each fixedly inserted at one end of the cooling water pipe. The air-cooling assembly consists of an air-cooling pipe, heat dissipation fins, inlet / outlet air pipes, a conical shell, and a miniature blower. Several heat dissipation fins are evenly fixedly installed longitudinally inside the air-cooling pipe. There are two inlet / outlet air pipes, each fixedly inserted at one end of the air-cooling pipe. The conical shell is fixedly installed at one end of one of the inlet / outlet air pipes, and a miniature blower is fixedly installed at one end of the conical shell.

[0006] Preferably, an installation groove is provided inside the lower mold and on the periphery of the mold cavity. Two first through grooves and two second through grooves are symmetrically provided at one end of the lower mold. Both the first through grooves and the second through grooves are connected to the installation groove, and the two first through grooves are located between the two second through grooves.

[0007] Preferably, the cooling water pipe on the water-cooled pipeline is located in the mounting groove, and the cooling water pipe is close to the inner wall of the mounting groove. Two first slots are opened on the outer walls of the beginning and end of the cooling water pipe. The inlet and outlet water pipes are fixedly inserted into the first slots. The inlet and outlet water pipes are also located in the first through groove. The inlet and outlet water pipes are connected to the cooling water circulation equipment through pipes.

[0008] Preferably, the air-cooling pipe on the air-cooling assembly is located in the mounting groove, and the air-cooling pipe is also tightly fitted onto the cooling water pipe, with two second slots opened on the outer walls of the air-cooling pipe at both ends.

[0009] Preferably, the heat dissipation fins on the air-cooling assembly are fixedly installed on the inner wall of the air-cooling duct, the air inlet and outlet ducts are fixedly inserted into the second slot, the air inlet and outlet ducts are simultaneously located in the second through groove, the conical shell is located on the outer side of the lower mold, and the micro blower is fixedly installed at the outer end of the lower mold.

[0010] Compared with the prior art, the present invention has the following beneficial effects: By installing a water-cooled pipeline consisting of cooling water pipes and inlet / outlet water pipes around the mold cavity of the lower mold, and cooperating with a cooling water circulation device, the flowing cooling water can directly and rapidly exchange heat with the outside of the mold cavity, efficiently removing the heat of the molten rubber inside the mold cavity and initially accelerating the cooling rate. Simultaneously, an air-cooling assembly consisting of air-cooled pipes, heat dissipation fins, inlet / outlet air pipes, a conical shell, and a miniature blower is installed around the water-cooled pipeline. The air-cooled pipes tightly wrap around the cooling water pipes, and the internal heat dissipation fins further expand the heat exchange area. The miniature blower passes through the conical shell... The body and air inlet / outlet ducts deliver flowing air into the air-cooled ducts, which not only assists in cooling the water-cooled ducts and maintains the cooling effect of the cooling water, but also directly provides air cooling to the area around the mold cavity inside the lower mold, forming a dual cooling structure of "water cooling + air cooling". This significantly improves the overall cooling efficiency, effectively shortens the curing time of the rubber shock-absorbing pads, increases the product output per unit time, and meets the needs of large-scale mass production. At the same time, dual cooling ensures that the temperature inside the mold cavity drops rapidly, avoiding problems such as uneven rubber shrinkage and surface depressions caused by slow cooling.

Detailed Implementation

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] Please see Figures 1-5As shown, a molding die for a rubber shock absorber includes a lower die 1 and an upper die 2. A water-cooled pipe 3 and an air-cooled assembly 4 are fixedly installed inside the lower die 1 and around its cavity. The water-cooled pipe 3 is fixedly installed inside the air-cooled assembly 4 and is connected to a cooling water circulation system. The water-cooled pipe 3 consists of a cooling water pipe 8 and inlet / outlet water pipes 10. There are two inlet / outlet water pipes 10, which are respectively fixedly inserted into the ends of the cooling water pipe 8. The air-cooled assembly 4 consists of an air-cooled pipe 11, heat dissipation fins 13, inlet / outlet air pipes 14, and a conical... The system comprises a housing 15 and a miniature blower 16. Several heat dissipation fins 13 are longitudinally and evenly fixedly installed within the air-cooled duct 11. Two inlet and outlet air ducts 14 are fixedly inserted into the beginning and end of the air-cooled duct 11, respectively. A conical housing 15 is fixedly installed at one end of one of the inlet / outlet air ducts 14, and a miniature blower 16 is fixedly installed at one end of the conical housing 15. By setting a water-cooled pipe 3 consisting of a cooling water pipe 8 and inlet / outlet water pipes 10 around the mold cavity of the lower mold 1, and cooperating with a cooling water circulation system, the system can utilize… The flowing cooling water directly and rapidly exchanges heat with the outer periphery of the mold cavity, efficiently removing the heat from the molten rubber inside the mold cavity and initially accelerating the cooling rate. At the same time, an air-cooling assembly 4, consisting of an air-cooling pipe 11, heat dissipation fins 13, inlet and outlet air pipes 14, a conical shell 15, and a micro blower 16, is installed around the water-cooling pipe 3. The air-cooling pipe 11 tightly wraps around the cooling water pipe 8, and the heat dissipation fins 13 inside can further expand the heat exchange area. The micro blower 16 delivers flowing air into the air-cooling pipe 11 through the conical shell 15 and the inlet and outlet air pipes 14. This not only assists in cooling the water-cooling pipe 3 and maintains the cooling effect of the cooling water, but also directly dissipates heat from the lower mold 1 around the mold cavity area, forming a dual cooling structure of "water cooling + air cooling". This significantly improves the overall cooling efficiency, effectively shortens the curing time of the rubber shock-absorbing pad, increases the product output per unit time, and meets the needs of large-scale mass production. At the same time, dual cooling can ensure that the temperature inside the mold cavity drops rapidly, avoiding problems such as uneven rubber shrinkage and surface depression caused by slow cooling.

[0015] Specifically, an installation groove 5 is provided inside the lower mold 1 and on the periphery of the mold cavity. Two first through grooves 6 and two second through grooves 7 are symmetrically provided at one end of the lower mold 1. Both the first through grooves 6 and the second through grooves 7 are connected to the installation groove 5. The two first through grooves 6 are located between the two second through grooves 7. The cooling water pipe 8 on the water-cooled pipe 3 is located inside the installation groove 5 and is in close contact with the inner wall of the installation groove 5. Two first slots 9 are provided on the outer walls of the two ends of the cooling water pipe 8. The inlet and outlet water pipes 10 are fixedly inserted into the first slots 9. The inlet and outlet water pipes 10 are also located in the first through grooves 6. The inlet and outlet water pipes 10 are connected to the cooling water circulation equipment through pipes. The air-cooled pipe 11 on the air-cooled assembly 4 is located inside the installation groove 5. Furthermore, the air-cooled pipe 11 is tightly fitted onto the cooling water pipe 8. Two second slots 12 are opened on the outer walls of both ends of the air-cooled pipe 11. The heat dissipation fins 13 on the air-cooled assembly 4 are fixedly installed on the inner wall of the air-cooled pipe 11. The inlet and outlet air pipes 14 are fixedly inserted into the second slots 12. The inlet and outlet air pipes 14 are also located in the second through groove 7. The conical shell 15 is located on the outside of the lower mold 1. The miniature blower 16 is fixedly installed at the outer end of the lower mold 1. When using this molding die for rubber shock-absorbing pads to produce rubber shock-absorbing pads, it is necessary to first ensure that the inside of the mold cavity of the lower mold 1 is clean and free of impurities, and at the same time confirm that the inlet and outlet water pipes 10 are securely connected to the external cooling water circulation equipment through the pipes; then The lower mold 1 and upper mold 2 are closed, and then molten rubber material is evenly injected into the cavity of the lower mold 1, ensuring that the material filling amount meets the molding requirements of the rubber shock-absorbing pad and that no air bubbles are mixed in. Immediately afterwards, the cooling water circulation equipment is started, allowing cooling water to enter the cooling water pipe 8 through one of the inlet / outlet pipes 10 and flow within the cooling water pipe 8, and then flow back to the cooling water circulation equipment from the other inlet / outlet pipe 10. During this process, the water flow absorbs and carries away the heat transferred from the molten rubber in the mold cavity to the cooling water pipe 8, thus utilizing the heat exchange between the cooling water and the lower mold 1 cavity to remove the heat from the molten rubber in the mold cavity. Simultaneously, the micro blower 16 is started, and the airflow generated by the micro blower 16 passes through the conical shell. 15 enters one of the air inlet / outlet ducts 14 and then flows into the air-cooling duct 11. When the airflow flows in the air-cooling duct 11, it comes into contact with the air-cooling duct 11 and the heat dissipation fins 13 inside the air-cooling duct 11, absorbing the heat transferred by the cooling water pipe 8 and the heat around the mold cavity area of ​​the lower mold 1. Finally, the airflow after absorbing the heat flows out from the other air inlet / outlet duct 14. After the rubber material in the mold cavity is completely cooled and solidified under the dual cooling effect to form a rubber shock-absorbing pad, the micro blower 16 and the cooling water circulation equipment are turned off to stop the air cooling and water cooling process. Then, the upper mold 2 is driven to move upward and separate from the lower mold 1. Finally, the formed rubber shock-absorbing pad is taken out from the mold cavity of the lower mold 1, completing the production of one rubber shock-absorbing pad.

[0016] Specifically, in the actual application of the molding die for the rubber shock absorber, the lower mold 1 and the upper mold 2 need to be installed in the relevant positions of the injection molding machine. The injection molding machine is used to complete the closing of the lower mold 1 and the upper mold 2 and the separation of the lower mold 1 and the upper mold 2. At the same time, the injection molding machine is used to inject molten rubber into the mold cavity of the lower mold 1. This is within the scope of existing technology and will not be discussed in detail here.

[0017] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
