Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold with anti-deviation and fast molding. Background Art

[0002] Injection mold is a tool for producing plastic products, and also a tool for giving plastic products a complete structure and precise size. Injection molding is a processing method used in mass production of certain parts with complex shapes. Specifically, it refers to the high-pressure injection of heated and melted plastic into the mold cavity by the injection molding machine, and after cooling and solidification, the molded product is obtained. The structure of the mold may vary depending on the type and performance of the plastic, the shape and structure of the plastic product, and the type of injection machine.

[0003] In the prior art, a Chinese patent with a publication number of "CN210617141U" discloses a fast molding injection mold, in which a cooling cavity is provided in the lower mold, a molding mold of the cooling cavity is fixedly installed in the cooling cavity, and a water inlet pipe and a water outlet pipe are respectively connected to the two side walls of the cooling cavity. Tap water enters the cooling cavity through the water inlet pipe, and the injection material in the molding mold can be quickly cooled down, thereby accelerating the molding efficiency, solving the problems that the existing injection molds have certain shortcomings in the molding process of the product, for example, the molding efficiency of the product is low, and the heat dissipation effect of the injection mold is insufficient and the practicality is poor.

[0004] However, the existing technology still has major deficiencies, such as:

[0005] During the use of the injection mold, the injection raw material will be injected into the mold cavity, and then the finished molded product will be obtained by cooling and fixing. Now, in order to make the injection molded product in the module faster, a cooling mechanism is usually added to the module. As in the scheme described above, a cooling chamber is added in the lower module, and cold water is injected into the cooling chamber to cool the module. However, after the cold water is injected into the cooling chamber, the heat in the cold water cannot be discharged after the cold water absorbs the heat of the module, which affects the effect of water cooling. Moreover, when the cold water becomes hot water, it needs to be discharged and re-injected with cold water, which is more troublesome. Utility Model Content

A limit slider is fixedly installed on the end surface of the lifting plate 7.

The top end of the limit rod 8 is installed on the inner top of the bracket plate 4, and the bottom end of the limit rod 8 is installed on the workbench 1;

[0030] A cooling chamber 5 is provided in the lower module 3, and a cooling component and an air cooling component are installed on the workbench 1, which facilitates rapid molding of the injection molded product in the injection mold;

[0031] The cooling assembly includes a water tank 10, on which a water pump 11 is installed. The output end of the water pump 11 is connected to a through pipe 12, and the end of the through pipe 12 away from the water pump 11 is connected to a shunt pipe 13, and the end of the shunt pipe 13 away from the shunt pipe 13 is connected to a through pipe 2 14, and the end of the through pipe 2 14 away from the shunt pipe 13 is connected to a cooling chamber 5, and the rear side of the water tank 10 is connected to a through pipe 3 15, and the end of the through pipe 3 15 away from the water tank 10 is connected to the cooling chamber 5, so that the injection mold can be quickly formed through the water circulation in the water tank 10.

[0032] In this embodiment, when the two modules are molded, the upper module 2 will follow the lifting plate 7 to descend through the lower position of the limit rod 8, ensuring that there will be no offset when the upper module 2 and the lower module 3 are molded, and the cold water in the water tank 10 is passed through the cooling chamber 5 of the lower module 3 by the water pump 11, so as to facilitate the rapid cooling and molding of the injection molded product inside the mold body, thereby improving the practicality of the device.

[0033] Embodiment 2:

[0034] On the basis of the first embodiment, in order to make the temperature of the cold water in the cooling chamber 5 cool down faster, this effect is achieved by fan blades 19. The air cooling component includes a mounting shell 16 and a heat conducting plate 20. The mounting shell 16 is mounted on the shunt pipe 13. A rotating shaft 17 is rotatably mounted inside the mounting shell 16. A turbine 18 and fan blades 19 are mounted on the rotating shaft 17. The turbine 18 is located inside the mounting shell 16, and the fan blades 19 are located outside the mounting shell 16. The heat conducting plate 20 is mounted on the inner bottom of the cooling chamber 5. A plurality of heat dissipating fins 21 are mounted on the heat conducting plate 20. Part of the volume of the heat conducting plate 20 is in contact with the cold water in the cooling chamber 5, and part of the volume is in contact with the lower module 3. A heat dissipation groove 22 is provided on the lower end surface of the lower module 3, and part of the volume of the heat dissipation fin 21 is located inside the heat dissipation groove 22.

[0035] In this embodiment, the heat absorbed by the cold water and the heat of the lower module 3 itself are transferred to the heat dissipation fins 21 through the heat conduction plate 20. Then, when the cooling water in the water tank 10 is passed into the cooling chamber 5, the flow of water is used to drive the turbine 18 in the mounting shell 16 to rotate. When the turbine 18 rotates, the fan blades 19 are simultaneously driven to rotate. The airflow generated by the fan blades 19 is blown toward the heat dissipation fins 21, which accelerates the heat dissipation of the heat dissipation fins 21 while improving the molding of the injection molded product inside the mold body, thereby further improving the practicability of the device.

[0036] Working principle:

[0037] When in use, the hydraulic cylinder 6 drives the lifting plate 7 to descend, and the lifting plate 7 drives the upper module 2 to descend synchronously while descending. When the lifting plate 7 is descending, the limit rod 8 is used to ensure the stability of the lifting plate 7 during descent, and the lifting plate 7 also slides in the limit slide groove 9 through the limit slider, thereby ensuring that the upper module 2 and the lower module 3 will not deviate when the mold is closed;

[0038] After the injection molding raw material is injected into the mold, the cold water in the water tank 10 is input into the cooling chamber 5 in the lower module 3 through the through pipe 1 12, the shunt pipe 13, and the through pipe 2 14 by the water pump 11. At the same time, the cooling water will re-enter the cold water tank 10 through the through pipe 3 15. Through the circulation of cold water, the heat in the lower module 3 is conveniently taken away, and the molding of the injection molded product in the module is accelerated;

[0039] When cold water passes through the shunt pipe 13, it will drive the turbine 18 in the mounting shell 16 to rotate. When the turbine 18 rotates, it will drive the fan blades 19 to rotate through the rotating shaft 17. At this time, the heat of the cold water in the cooling chamber 5 will be transferred to the heat dissipating fins 21 through the heat conducting plate 20, and the heat in the lower module 3 will also be transferred to the heat dissipating fins 21 through the heat conducting plate 20. The wind force of the fan blades 19 can quickly dissipate the heat dissipated by the heat dissipating fins 21, making the effect of the heat dissipating fins 21 better, thereby improving the molding of the injection molded product in the module.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
