Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold with a cleaning function. Background Art

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of the injection molding method are fast production speed, high efficiency, and automated operation. Injection molding is suitable for mass production and molding processing fields such as products with complex shapes.

[0003] At present, the existing injection mold (such as patent number: CN219055149U) discloses an injection mold for injection molded parts. The covering structural design of several flow channels can effectively solve the technical problem of poor cooling effect at the edge of the square mold and reduced overall cooling efficiency. Moreover, there is no external added structure based on the original structure of the injection mold, which effectively reduces the overall production cost of the injection mold.

[0004] However, in the process of implementing the above technical solution, it was found that there are at least the following technical problems: the product is plasticized by heating inside the mold, and the heating causes the product and the mold to fit tightly. When taking the material, the product is taken out from the mold, which will cause some product scraps to remain inside the mold, affecting subsequent injection molding. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides an injection mold with a cleaning function, which solves the technical problem that a product is plasticized by heating inside the mold, and the heating causes the product to fit tightly with the mold. When taking out the material, the product is taken out from the mold, which will cause some product scraps to remain inside the mold, affecting subsequent injection molding.

[0007] (II) Technical solution

[0008] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] An injection mold with a cleaning function comprises a lower mold and an upper mold, wherein the two side ends of the lower mold are fixedly mounted with a base, the inner side of each of the bases is rotatably mounted with a side panel, the side end of each of the side panels is provided with an air outlet, and the side ends of the two bases are fixedly mounted with the same connecting pipe.

[0010] Preferably: two fixed blocks are fixedly installed at the bottom end of the upper mold, a connecting rod is rotatably installed at the bottom end of each of the fixed blocks, a rotating shaft is rotatably installed at the end of each of the connecting rods, a mounting opening is opened at the side end of each of the side panels, and a closing plate is movably installed at the end of each of the side panels.

[0019] The embodiment of the present application provides an injection mold with a cleaning function, which effectively solves the problem of heating causing the product to fit tightly with the mold. When taking out the material, the product is taken out from the inside of the mold, which will cause some product scraps to remain inside the mold, affecting the subsequent injection molding. The two closed plates are rotated and opened inside the base, and the airflow of the connecting pipe enters the inside of the side plate through the base. The upper mold moves upward and the two side plates are rotated toward the top of the lower mold. After the side plates are deflected and tilted upward, the airflow is blown to the top of the lower mold through the air outlet to cool the product inside. At the same time, after the product is taken out, the impurities inside the lower mold are cleaned by the airflow to prevent impurities from remaining and affecting the quality of injection molding.

[0020] Example

[0021] like Figure 1 , Figure 2 , Figure 3 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that heating causes the product to fit tightly with the mold. When taking out the material, the product is taken out from the inside of the mold, which will cause some product scraps to remain inside the mold, affecting the subsequent injection molding. The overall idea is as follows:

[0022] In view of the problems existing in the prior art, the utility model provides an injection mold with a cleaning function, including a lower mold 1 and an upper mold 11. The upper mold 11 is pushed by a hydraulic device to allow the upper mold 11 to move vertically downward at the top of the lower mold 1, so that the upper mold 11 fits with the top of the lower mold 1, and the raw material is injected into the lower mold 1 and the upper mold 11. At a certain temperature, the completely molten plastic material is stirred by a screw, and injected into the mold cavity with high pressure. After cooling and solidification, it is formed. The two side ends of the lower mold 1 are fixedly installed with a base 17, and each base 17 is fixedly installed with a base 17. The inner side of the seat 17 is rotatably mounted with a side panel 15, and the side end of each side panel 15 is provided with an air outlet 16. The side ends of the two bases 17 are fixedly mounted with the same connecting pipe 18, and the end of the connecting pipe 18 is connected to the air blowing device. The end of the side panel 15 is hollow in design and is connected with the connecting pipe 18. After the side panel 15 is deflected and tilted upward, the airflow is blown to the top of the lower mold 1 through the air outlet 16 to cool the product inside. At the same time, after the product is taken out, the impurities inside the lower mold 1 are cleaned by the airflow to prevent impurities from remaining.

[0023] Two fixed blocks 12 are fixedly installed at the bottom end of the upper mold 11, and a connecting rod 13 is rotatably installed at the bottom end of each fixed block 12. A rotating shaft 14 is rotatably installed at the end of each connecting rod 13. A threaded groove is provided on the surface of the rotating shaft 14, which fits with the end of the connecting rod 13. A mounting port 19 is provided at the side end of each side plate 15, and the end of the rotating shaft 14 is snap-fitted with the mounting port 19. A closing plate 21 is movably installed at the end of each side plate 15, and the end of the side plate 15 drives the closing plate 21 to rotate inside the base 17. The closing plate 21 is a split design. The rotation of the side plate 15 drives the closing plate 21 to close. At the same time, the rotating shaft 14 is rotated to rotate at the end of the connecting rod 13, and the surface of the rotating shaft 14 fits with the end of the connecting rod 13.

[0024] Working principle:

[0025] In the first step, the upper mold 11 is pushed by the hydraulic device, so that the upper mold 11 moves vertically downward at the top of the lower mold 1, so that the upper mold 11 fits with the top of the lower mold 1, and the raw material is injected into the lower mold 1 and the upper mold 11. At a certain temperature, the completely molten plastic material is stirred by the screw, and injected into the mold cavity with high pressure. After cooling and solidification, it is formed. In the process of the upper mold 11 moving downward, the upper mold 11 drives the fixed block 12 to move, and the fixed block 12 applies a force to the inclined connecting rod 13, so that the connecting rod 13 is tilted and rotated at the bottom end of the upper mold 11, and the end of the connecting rod 13 drives The rotating shaft 14 rotates the side end of the side plate 15, and the inclined connecting rod 13 applies a thrust to the side plate 15, so that the side plate 15 deflects outward inside the base 17, and the end of the side plate 15 drives the closing plate 21 to rotate inside the base 17. The closing plate 21 is a split design. The rotation of the side plate 15 drives the closing plate 21 to close. At the same time, by rotating the rotating shaft 14, the rotating shaft 14 is rotated at the end of the connecting rod 13. The surface of the rotating shaft 14 fits with the end of the connecting rod 13, allowing the rotating shaft 14 to rotate at the end of the connecting rod 13, and the end of the rotating shaft 14 is rotated to leave the inside of the mounting opening 19.

[0026] In the second step, after the injection molding is completed, the air flow is output to the inside of the two side panels 15 through the connecting pipe 18. The end of the connecting pipe 18 is connected to the blasting equipment, and the upper mold 11 moves upward, so that the upper mold 11 drives the connecting rod 13 to deflect upward. The inclination of the connecting rod 13 allows the rotating shaft 14 to apply a pulling force to the side panels 15, so that the side panels 15 deflect upward inside the two bases 17. At the same time, the side panels 15 rotate, and the two closed panels 21 rotate and open inside the base 17. The air flow of the connecting pipe 18 enters the inside of the side panels 15 through the base 17, and the upper mold 11 moves upward, The two side panels 15 are rotated toward the top of the lower mold 1. After the side panels 15 are deflected and tilted upward, the air flow is blown to the top of the lower mold 1 through the air outlet 16 to cool the internal product. At the same time, after the product is taken out, the impurities inside the lower mold 1 are cleaned by the air flow to prevent impurities from remaining and affecting the quality of injection molding.

[0027] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
