Description

Technical Field

[0001] The utility model relates to the technical field of injection molding, in particular to an injection molding mold for an automobile interior trim panel. Background Art

[0002] Injection mold is a tool for producing plastic products; it is also a tool that gives plastic products a complete structure and precise dimensions. Injection molding is a processing method used in mass production of certain parts with complex shapes. Specifically, it refers to the process of injecting heated and melted plastic into the mold cavity under high pressure by an injection molding machine, and then cooling and solidifying to obtain a molded product. 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 molding machine.

[0003] The Chinese patent with the publication number CN213382828U discloses an injection mold for an automobile interior trim panel with a heat dissipation function. The patent includes a box body and a fixed mold. The fixed mold is fixedly installed in the middle of the box body. The bottom end of the fixed mold is wrapped with a coil. One end of the coil is connected to one side of the water tank. The other side of the water tank is connected to the input end of the water pump. The output end of the water pump is connected to the other end of the coil. The water pump and the water tank are both fixedly installed at the bottom end of the box body. The top of the fixed mold is provided with a movable mold. The top of the movable mold is connected and installed with a telescopic cylinder, and the telescopic cylinder is installed through the top of the box body. The patent uses two fans to air-cool the top surface of the fixed mold, and uses surrounding water cooling to water-cool the bottom surface of the fixed mold to take away the heat inside the fixed mold, thereby quickly dissipating heat and facilitating the demolding of the automobile interior trim panel in the mold by the staff.

[0004] Based on the above search and combined with the prior art, we found that:

[0005] There are various models of cars today. When manufacturing car interior panels, different types need to be made according to different models. However, the existing technology mainly improves the heat dissipation of injection molds of the same model. In industrial production, only the same model of molds can be made, which will lead to limitations and is not conducive to production operations. In addition, in the existing technology, one mold can only be made after one mold is cooled down, and the work efficiency is not high. Utility Model Content

[0006] In order to solve the above technical problems, the utility model proposes an injection mold for an automobile interior trim panel. The device is provided with a second support frame installed on a pair of turntables, and a movable column is rotatably connected between the second support frames. The mold box is clamped on the carrier plate by a buckle, and a pair of sockets are opened on the carrier plate. The latch is rotatably connected with the buckle. The latch is inserted into the socket and then the buckle is rotated, so that the buckle can be clamped on the carrier plate. A second connecting column is rotatably connected below the buckle, and the other end of the second connecting column is detachably connected to the mold box. When different types of molds need to be produced, it is only necessary to remove the mold box from the second connecting column and then clamp the replaced mold box on the carrier plate. Injection molding on a carrier plate solves the problem of limitations caused by only being able to produce molds of the same type. There are multiple carrier plates between a pair of turntables. When the turntable rotates, it drives the mold box clamped on the carrier plate to move. The mold box is first filled with material through a feed pipe, and then rotated to the cooling box below for rapid cooling and shaping. After cooling, it is rotated to the corresponding position and removed for demolding. Finally, it is rotated to the corresponding position and the empty mold box is re-clamped, and then the above-mentioned injection molding operation is performed. Such a cyclic operation improves work efficiency. When changing different types of molds, it is not affected by the previous type of mold, which is beneficial to industrial production.

[0007] The technical solution to achieve the purpose of the utility model is: an injection mold for an automobile interior trim panel, including a base, a support plate fixedly mounted on the base, a rotating column rotatably mounted on the support plate, a worm wheel fixedly mounted on the rotating column, a pair of first support frames fixedly mounted on the support plate, a worm rotatably mounted on one of the first support frames, a motor fixedly mounted on the other first support frame, the output shaft of the motor is fixedly connected to one end of the worm, a pair of turntables fixedly mounted on the rotating column, a plurality of pairs of second support frames fixedly mounted on the pair of turntables, movable columns rotatably mounted between the plurality of pairs of second support frames, a pair of first connecting columns fixedly mounted below the movable columns, and a bearing plate commonly mounted on the other ends of the pair of first connecting columns.

[0008] In some embodiments, a mold box is clamped under the carrier plate, a feed port is opened on the mold box, a second connecting column is detachably connected above the mold box, a buckle is rotatably installed above the second connecting column, and a latch is rotatably installed on the buckle.

[0011] In some embodiments, a cooling box is fixedly mounted on the base, and cold water is filled in the cooling box.

[0012] In some embodiments, the feed tube opening position corresponds to the feed port position.

[0013] Compared with the prior art, the present invention has the following significant advantages:

[0014] First, the utility model aims at the existing injection mold for automobile interior trim panels with heat dissipation function, which has the problem that only the same type of mold can be produced, which will cause limitations and is not conducive to production operations.

[0015] Secondly: The utility model aims at the existing injection mold for automobile interior trim panels with heat dissipation function, which has the problem that the next mold can only be made after one mold is cooled down, resulting in low work efficiency. The device has multiple carrying plates between a pair of turntables. When the turntable rotates, it drives the mold box clamped on the carrying plate to move. The mold box is first filled with material through a feeding pipe, and then rotated to the cooling box below for rapid cooling and shaping. After cooling, it is rotated to the corresponding position and removed for demolding.
