[0014] The present invention provides an automotive interior decoration injection mold with a cooling structure. It has the following beneficial effects: 1. The automotive interior parts injection mold with a cooling structure allows the limit plate to be stuck on the left side of the limit lock by the limit lock when the mold is closed by shaking the assembly. When the mold is opened, the ejector rod contracts and the limit lock is pressed down by the pressing block fixedly connected to its bottom during the contraction, thereby releasing the limit on the limit plate, so that the limit plate is ejected by the spring 1, and the elastic guide column quickly pushes the fixed template 2, thereby driving the concave mold and the convex mold to shake on the guide plate through the connection, so that the molded plastic part and the mold are loosened due to the shaking, which is beneficial to the demolding of the mold, thereby improving the efficiency of injection molding.
[0015] 2. The automotive interior injection mold with a cooling structure pushes the ejector rod inward through the internal pressure after the cavity is fully injected, so that all the movable plates are rotated and unfolded through the connection, and the heat of the mold is transferred to the movable plate through the contact block, so that the fan frame dissipates heat to the movable plate and the inside of the concave mold, and cools the mold, so that the internal plastic parts can be stably formed, which is conducive to demolding and thus improves the efficiency of injection molding.
[0016] 3. The automotive interior injection mold with a cooling structure has a fourth spring that restores its deformation to drive the rotating rod to press the movable plate close to the rotating rod when the mold is opened. The movable plate drives the remaining movable plates to rotate through the linkage rod. At the same time, one of the movable plates cooperates with the third spring to push the ejector rod outward, thereby achieving the effect of pushing out the plastic part, thereby facilitating demoulding and improving the efficiency of injection molding.
[0017] 4. The automotive interior injection mold with a cooling structure can achieve the effect of loosening the dust on the mold surface by shaking the shaking component when opening the mold. When the movable plate is opened to allow the fan frame to blow air into the punch, the loose dust can be blown out, thereby preventing the heat dissipation effect from being weakened due to dust accumulation, thereby achieving the effect of improving the cooling of the plastic part, which is beneficial to the molding of the plastic part and can improve the efficiency of injection molding.
[0018] 5. The automotive interior injection mold with a cooling structure generates shaking when the mold is opened through the shaking component, and the fixed template 2 is quickly pushed by the elastic guide column. Because the fixed template 2 is fixed to the movable plate through the fixing frame, the movable plate can be quickly closed by inertia, thereby increasing the force pushing the push rod inward, which is beneficial to demolding and can improve the efficiency of injection molding.
[0019] 6. The automotive interior injection mold with a cooling structure has two cylinders that fill the internal gas into the guide shell through the air guide pipe when the mold is closed, so that the gas pushes the cutting block. After the injection molding is completed, the plastic part is no longer pushed into the chamber. The air pressure on the cutting block is greater than the pressure in the chamber. The cutting block will close again under the action of the air pressure, so that the injection plastic and the molded plastic part can be disconnected, thereby preventing the injection plastic and the plastic part from sticking to each other during demolding and making it difficult to demold, which can improve the efficiency of injection molding.

[0025] Four elastic guide pillars 34 are fixedly connected to the right side of the fixed template 1 21 , and the four elastic guide pillars 34 are fixedly connected to the right side of the fixed template 2 23 . Four springs 1 32 are provided, and four fixed pillars 24 are provided.

[0027] The spring 32 is pressed against the bottom of the mold to release the limit lock 36, and the limit plate 33 is pushed down by the elastic guide column 34, thereby releasing the limit plate 33 and allowing the limit plate 33 to be ejected by the spring 32. At the same time, the elastic guide column 34 can quickly push the fixed template 23, thereby driving the die 22 and the punch 28 to shake on the guide plate 1 through the connection, so that the molded plastic part and the mold are loosened due to the shaking, which is beneficial for the demolding of the mold.
[0028] For example 2, please refer to Figure 1-13 Based on the first embodiment, the present invention provides a technical solution: The cooling mechanism 4 includes a fan frame 41, and the fan frame 41 is fixedly connected to the left side of the fixing plate 25.

A spring three 43 is fixedly connected to the left side of the limiting plate 421. The left side of the push rod 42 is fixedly connected to the punch 28.
[0030] Eight movable plates 45 are arranged on the right side of the punch 28, and the left and right ends of the eight movable plates 45 are fixedly connected with fixed frames 46, and the fixed frames 46 are rotatably connected to the corresponding movable plates 45, and the fixed frames 46 are fixedly connected inside the fixed template 23, and the left and right movable plates 45 are movably connected with linkage rods 47, and the linkage rods 47 are rotatably connected to the movable plates 45, and the two linkage rods 47 are movably connected to all the movable plates 45, and a rotating frame 48 is fixedly connected to the top of the punch 28, and a rotating rod 49 is movably connected inside the rotating frame 48, and the rotating rod 49 is rotatably connected to the rotating frame 48, and the rotating rod 49 is movably connected to one of the movable plates 45, and a spring four 491 is fixedly connected to the outer wall of the rotating rod 49, and the end of the spring four 491 away from the rotating rod 49 is fixedly connected to the rotating frame 48.
[0031] The outer wall of the movable plate 45 is located inside the punch 28 and is fixedly connected to two connecting grooves 451, and only the outer walls of the three movable plates 45 closest to the push rod 42 are fixedly connected to the connecting grooves 451, and each connecting groove 451 is movably connected to a contact block 452, and a spring 5 453 is fixedly connected to the connecting groove 451, and the end of the spring 5 453 away from the fixed connection with the connecting groove 451 is fixedly connected to the contact block 452.

When the ejector pin 42 reaches a certain limit, it will no longer be pushed inwards by the limit piece 421 and the limit rod 44 on the ejector pin 42, and the ejector pin 42 will pull up the spring 43. During the pressing process, the ejector pin 42 will push open one of the movable plates 45 connected to the fixed frame 46 at both ends to rotate, so that this movable plate 45 drives the other movable plates 45 to rotate through the linkage rod 47, so that the movable plates 45 are opened, and the three movable plates When it is opened, the connecting groove 451 fixedly connected to the outside will rotate together, and when rotating, the contact block 452 will contact and fit with the inside of the punch 28, so that the heat is transferred to the fan frame 41, and the airflow blown out by the fan inside the fan frame 41 is blown into the inside of the punch 28 through the gap formed by the opening of the movable plate 45, so as to cool the mold, thereby stably forming the internal plastic parts and facilitating demoulding.

[0033] For example 3, please refer to Figure 1-14 Based on the first and second embodiments, the present invention provides a technical solution: The demolding assembly 5 includes a main channel 55, which is fixedly connected to the right side of the die 22.

The outer wall of each cylinder 51 is fixedly connected to a fixed block 52. The two fixed blocks 52 are respectively fixedly connected to the front and rear sides of the fixed template 1 21. The left sides of the two cylinders 51 are fixedly connected to air guide pipes 53, and the two air guide pipes 53 are respectively fixedly connected to the corresponding guide shells 54.
[0034] A cutting block 57 is movably connected inside the main channel 55 , and a limiting block 56 is arranged inside the main channel 55 on a side of the cutting block 57 away from the main channel 55 .
[0035] When in use, when the mold is being matched, the fixed template 23 compresses the two cylinders 51, and the two cylinders 51 will press the internal gas into the guide shell 54 through the corresponding air guide pipe 53. The gas pressure inside the guide shell 54 will increase, thereby pushing the two cutting blocks 57 to close. When injection molding is performed through the main channel 55, the injection pressure can push the two cutting blocks 57 to press into the guide shell 54 for injection molding. After the injection molding is completed, the plastic part is no longer pushed into the chamber. The air pressure on the cutting block 57 is greater than the pressure in the chamber. The cutting block 57 will close again under the action of the air pressure, thereby disconnecting the injection plastic from the molded plastic part, thereby preventing the injection plastic from sticking to the plastic part and making it difficult to demold during demolding.
