Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to an injection mold that is easy to use for injection molding. Background Technology

[0002] Injection molding is an important molding method in the modern plastics industry. It involves injecting molten plastic into a mold cavity, which then cools and solidifies to obtain a plastic product of the desired shape. With economic development and market acceptance, mold manufacturing has become one of the key elements for measuring the level of a country's manufacturing industry.

[0003] In some traditional molds, the ejection of the molded part usually requires the use of tools to remove it from the mold. This is not only time-consuming and labor-intensive, but also prone to being subjected to large impact forces during the ejection process, which accelerates the wear and damage of the mold and shortens its service life. In addition, the cooling system of traditional molds usually uses disposable cooling water, which wastes water resources. In order to solve the above problems, this utility model provides an injection mold that is easy to use for injection molding. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an injection mold that facilitates injection molding.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An injection mold for easy injection molding includes a base, a worktable fixedly connected to the upper surface of the base, a lower mold fixedly connected to the upper surface of the worktable, a support frame fixedly connected to the upper surface of the worktable, a threaded screw rotatably connected inside the support frame, a lifting platform threadedly sleeved on the surface of the threaded screw, an upper mold fixedly connected to the lower surface of the lifting platform, a demolding assembly provided inside the upper mold, an installation groove provided inside the lower mold, a heat dissipation pipe fixedly connected inside the installation groove, and a circulation assembly fixedly connected to the upper surface of the base.

[0007] As a further improvement of this utility model, the demolding assembly includes several sleeve rods disposed inside the upper mold, each sleeve rod having a piston rod movably connected inside, the upper ends of the piston rods being fixedly connected to the same connecting frame, and the upper surface of the lifting platform having two fixed rods fixedly connected, the middle ends of the two fixed rods being fixedly connected to an electric push rod, and the telescopic ends of the two electric push rods being fixedly connected to the connecting frame.

[0008] As a further improvement of this utility model, the circulation component includes a storage box fixedly connected to the middle of the upper surface of the base, a cooling box fixedly connected to one side of the upper surface of the base, a water pump fixedly connected to one side of the workbench, a water supply pipe fixedly connected to the output end of the water pump, a heat dissipation pipe fixedly connected to the other end of the water supply pipe, a water pumping pipe fixedly connected to the input end of the water pump, and a water pumping pipe fixedly connected to the other end of the water pump, which is fixedly connected to the storage box.

[0009] As a further improvement of this utility model, a circulation pipe is fixedly connected to the front of the cooling box, the other end of the circulation pipe is fixedly connected to the storage box, a valve is fixedly connected to the surface of the circulation pipe, a connecting pipe is fixedly connected to the other end of the heat dissipation pipe, and the other end of the connecting pipe is fixedly connected to the cooling box.

[0010] As a further improvement of this utility model, a drive motor is fixedly connected to the lower end of the support frame, and the power end of the drive motor is fixedly connected to the threaded screw.

[0011] As a further improvement of this utility model, an injection tube is fixedly connected to the middle of the upper mold, and limit grooves are opened on both sides of the lifting platform. Limiting rods that are compatible with the limit grooves are fixedly connected to both sides of the support frame.

[0012] The beneficial effects of this utility model are:

[0013] By setting up a lifting platform, the mold can be quickly and accurately closed during use through the cooperation of the drive motor and the screw thread. This reduces the time spent on manual operation and improves the overall production efficiency. At the same time, the precise control of mold closure helps to ensure the dimensional accuracy and shape stability of the injection molded parts, thereby improving product quality.

[0014] By setting up a circulation component, when in use, the water pump is started to draw cooling water from the storage tank and inject it into the heat dissipation pipe, which quickly removes the heat inside the mold, preventing the injection molded parts from deforming or shrinking due to excessive temperature, reducing the thermal stress generated by the mold due to prolonged high-temperature operation, thereby extending the service life of the mold and improving its quality. At the same time, the cooling water flows back to the cooling tank after passing through the heat dissipation pipe, and then returns to the storage tank through the circulation pipe, realizing the effective use of water resources and reducing water waste.

[0015] By setting up a demolding assembly, the pressure provided by the electric push rod during use ensures that the cooled mold adheres tightly to the upper mold, guaranteeing the stability of the mold during movement. When the upper mold is driven upward by the drive motor, the molded part moves completely with the upper mold because it is already tightly adhered to it, thus improving the efficiency and accuracy of material ejection. At the same time, by precisely controlling the pressure of the electric push rod, excessive impact force on the mold during ejection can be avoided, thereby reducing mold wear and damage and extending the service life of the mold.

[0016] In summary, this utility model achieves beneficial effects such as improved production efficiency, guaranteed product quality, energy saving and environmental protection, enhanced ease of operation, and extended mold life by optimizing key production processes such as mold closing, raw material injection, and cooling system.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4An injection mold for easy injection molding includes a base 1, a worktable 2 fixedly connected to the upper surface of the base 1, a lower mold 3 fixedly connected to the upper surface of the worktable 2, a support frame 4 fixedly connected to the upper surface of the worktable 2, a threaded screw 5 rotatably connected inside the support frame 4, a lifting platform 6 threadedly sleeved on the surface of the threaded screw 5, an upper mold 7 fixedly connected to the lower surface of the lifting platform 6, a demolding component provided inside the upper mold 7, an installation groove provided inside the lower mold 3, a heat dissipation pipe 8 fixedly connected inside the installation groove, and a circulation component fixedly connected to the upper surface of the base 1.

[0024] In this invention, the demolding assembly includes several sleeve rods 9 disposed inside the upper mold 7. The sleeve rods 9 serve as the movable track for the piston rod 10, ensuring the stability and accuracy of the piston rod 10 during movement. The piston rod 10 is movably connected inside each of the sleeve rods 9. The up-and-down movement of the piston rod 10 within the sleeve rods 9 provides the power for the adsorption and release of the mold. The upper ends of the several piston rods 10 are fixedly connected to the same connecting frame 11. The connecting frame 11 serves as the force-bearing point for the electric push rod 13, enabling unified control of the piston rod 10. Two fixed rods 12 are fixedly connected to the upper surface of the lifting platform 6. The middle ends of the two fixed rods 12 are fixedly connected to the electric push rods 13. The telescopic ends of the two electric push rods 13 are fixedly connected to the connecting frame 11. Through the telescopic movement of the electric push rods 13, the movement distance of the piston rod 10 within the sleeve rods 9 can be precisely controlled, thereby achieving tight adsorption and smooth release of the mold.

[0025] The circulation assembly includes a storage tank 14 fixedly connected to the middle of the upper surface of the base 1. A cooling tank 15 is fixedly connected to one side of the upper surface of the base 1. The cooling tank 15 is used to receive and cool the hot water flowing out from the heat dissipation pipe 8. A water pump 16 is fixedly connected to one side of the workbench 2. A water supply pipe 17 is fixedly connected to the output end of the water pump 16. The water pump 16 provides power for the circulation of cooling water. The other end of the water supply pipe 17 is fixedly connected to the heat dissipation pipe 8. The cooling water in the heat dissipation pipe 8 absorbs heat from the mold and its temperature rises. The input end of the water pump 16 is fixedly connected to... There is a water pumping pipe 18, the other end of which is fixedly connected to the storage tank 14. A circulation pipe 19 is fixedly connected to the front of the cooling tank 15, the other end of which is fixedly connected to the storage tank 14. The circulation pipe 19 serves as a channel for cooling water to return from the cooling tank 15 to the storage tank 14. A valve 20 is fixedly connected to the surface of the circulation pipe 19. A connecting pipe 24 is fixedly connected to the other end of the heat dissipation pipe 8, the other end of which is fixedly connected to the cooling tank 15. The connecting pipe 24 guides the hot water in the heat dissipation pipe 8 into the cooling tank 15 for cooling.

[0026] A drive motor 21 is fixedly connected to the lower end of the support frame 4. The drive motor 21 provides power for the rotation of the threaded screw 5. The power end of the drive motor 21 is fixedly connected to the threaded screw 5. The rotation of the threaded screw 5 drives the lifting platform 6 to move up and down. An injection tube 22 is fixedly connected to the middle of the upper mold 7. The injection tube 22 serves as a channel for raw material injection, ensuring that the raw material can accurately enter the mold cavity. Limiting grooves are opened on both sides of the lifting platform 6. Limiting rods 23 that are compatible with the limiting grooves are fixedly connected to both sides of the support frame 4. The cooperation between the limiting rods 23 and the limiting grooves ensures the stability and accuracy of the lifting platform 6 during movement.

[0027] When using this utility model, first start the drive motor 21 to drive the threaded screw 5 to rotate and drive the lifting platform 6 to move downward until the upper mold 7 under the lifting platform 6 and the lower mold 3 on the worktable 2 are closed. Start the injection pipe 22 to accurately inject the molten material into the cavity formed by the upper mold 7 and the lower mold 3. After the material is completely injected and filled, start the water pump 16 to draw cooling water from the storage tank 14 through the water pumping pipe 18 and introduce it into the heat dissipation pipe 8 inside the lower mold 3 through the water supply pipe 17. After the cooling water effectively absorbs the heat released by the mold in the heat dissipation pipe 8, it continues to flow and is guided to the cooling box 15 for cooling treatment through the connecting pipe 24.

[0028] After the mold has been sufficiently cooled, the electric push rod 13 is activated. The electric push rod 13, through the connecting frame 11, links several piston rods 10 to move upward inside the sleeve rod 9, thereby generating the necessary pressure. This causes the cooled mold to adhere tightly to the surface of the upper mold 7. Then, the drive motor 21 is activated again to drive the upper mold 7, along with the mold attached to it, to move upward together. Subsequently, the discharge device is placed directly below the upper mold 7, and the electric push rod 13 is operated again to release the applied pressure, allowing the mold to smoothly separate and detach from the upper mold 7, completing the discharge step. Finally, after the water in the cooling tank 15 has been sufficiently cooled, the valve 20 is opened, allowing the cooling water to flow back to the storage tank 14 through the circulation pipe 19 for use in the next cooling cycle.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
