Description

Technical Field

[0001] The present application relates to the field of mold technology, and more specifically, to a one-step molding mold for a radiator grille base. Background Art

[0002] The car radiator grille base is used to support and fix the radiator, and its processing method is usually to use a molding die to extrude the molten plastic into a mold.

[0003] After the radiator grille base is formed by the current molding mold, the mold cavity fits tightly with the product, making it difficult to remove the product. It is difficult to complete automatic processing in one go, and it takes time and effort to manually pull the product out. It is difficult to apply force when pulling it out manually, which is time-consuming and labor-intensive.

[0004] In view of this, a one-step forming mold for a radiator grille base is proposed. Utility Model Content

[0005] Purpose of the invention: To propose a one-time forming mold for a radiator grille base, so as to solve the technical problem in the above-mentioned background technology that after the radiator grille base is formed, the cavity of the mold fits tightly with the product, making it difficult to remove the product. In this way, it is difficult to complete the automatic processing in one go, and it is also necessary to spend time manually to pull out the product. It is difficult to apply force well when pulling it out manually, which is time-consuming and labor-intensive.

[0006] Technical solution: A one-step forming mold for a radiator grille base, comprising:

[0007] A fixed die seat and a movable die seat, wherein the fixed die seat is fixedly mounted with a fixed die block, and the movable die seat is slidably connected with a movable die block;

[0008] A cavity is provided in the middle of a surface facing the fixed module and the movable module;

[0009] Hydraulic rods, both sides of the top of the movable die seat are fixedly installed with hydraulic rods, and the output rods of the hydraulic rods are fixedly connected to the movable die block;

[0010] An opening and closing mechanism is installed on both sides of the movable module and between the fixed module;

[0011] An ejection mechanism is installed between the movable die block and the movable die base.

[0012] Through the above scheme, when the hydraulic rod pushes the moving module close to the fixed module for mold closing, the opening and closing mechanism automatically closes to make the cavity seal complete, and the ejection mechanism retracts into the moving module, thereby facilitating injection molding. After molding, the moving module is away from the fixed module to open the mold. At this time, the product is located in the cavity, and the opening and closing mechanism unfolds to release the product. At the same time, the ejection mechanism extends from the moving module into the cavity to separate the product from the cavity, making it easy for the product to fall and be collected, thereby achieving one-time automatic processing.

[0013] Optionally, guide grooves are opened on both sides of the top surface of the movable mold base, and guide plates are fixedly installed on both sides of the bottom of the movable mold block. The guide plates are slidably engaged with the guide grooves, and the cross-sections of the guide grooves and the guide plates are T-shaped structures.

[0014] The lockhole that is formed on the upper and lower surfaces of the movable module is formed on the movable module, and the lockhole that is formed on the movable module is formed on the movable module outer wall is provided with a spring.

[0015] Through the above scheme, when the mold is closed, the guide column contacts the inner wall of the truncated cone of the truncated cone hole, thereby squeezing the pressure plate to move toward the cavity, so that the core block fits the cavity, thereby achieving the purpose of complete closure of the cavity. When the mold is opened, the guide column gradually disengages from the through hole and finally gradually disengages from the truncated cone hole. At this time, the elastic force of the spring causes the slide rod to pull the core block away from the cavity, thereby achieving the purpose of loosening the product.

[0016] The transmission shaft is rotatably connected to the fixed module, and a bevel gear engaged with the gear is engaged with the gear of the gear train and the gear is engaged with the gear of the gear train.

[0017] Through the above scheme, when the mold is closed, the moving module is close to the fixed module. At this time, the teeth of the incomplete gear roll along the rack, so that the transmission shaft drives the screw to rotate through the bevel gear, and the top block slides into the storage cavity. When the teeth of the incomplete gear are engaged with the rack, the teeth on both sides of the toothless section just fit the stop surface, and the incomplete gear cannot rotate. At this time, the top block is aligned with the inner wall of the cavity, which is convenient for injection molding of the radiator grille base. When the mold is opened, the toothless section slides along the stop surface first, which is convenient for the core block to release the product. Then the incomplete gear moves to the rack, and the teeth mesh with the rack and roll, so that the screw drives the top block to extend out of the storage cavity, thereby ejecting the product released by the core block, which is convenient for the product to fall, and realizes one-time processing with higher efficiency.

[0018] Beneficial effects: 1. The present application drives the moving module to move by the hydraulic rod. When the mold is closed, the guide column contacts the inner wall of the truncated cone of the truncated cone hole, thereby squeezing the pressure plate to move toward the cavity, so that the core block fits with the cavity, and the cavity is completely closed. The moving module is close to the fixed module. At this time, the teeth of the incomplete gear roll along the rack, so that the transmission shaft drives the screw to rotate through the bevel gear, and the top block slides into the storage cavity. When the teeth of the incomplete gear are engaged with the rack, the teeth on both sides of the toothless segment just fit the stop surface, and the incomplete gear cannot rotate. At this time, the top block is aligned with the inner wall of the cavity, so as to facilitate the injection molding of the radiator grille base;

[0019] 2. When the mold is opened, the guide column gradually disengages from the through hole and finally from the truncated cone hole. At this time, the elastic force of the spring causes the slide rod to pull the core block away from the cavity, thereby releasing the product. The toothless segment first slides along the stop surface, which facilitates the core block to release the product. Then the incomplete gear moves to the rack, and the teeth mesh with the rack and roll, so that the screw drives the ejector block to extend out of the storage cavity, thereby ejecting the product released by the core block, making it easier for the product to fall, achieving one-time processing and higher efficiency.
