It bears the pressure and force during the stamping process. The upper mold is usually composed of the upper mold base, upper mold plate, upper guide column and other components. Its main function is to support and fix the lower mold so that it can perform stamping operations smoothly. In automobile molds, the internal plate refers to the inner plate of the mold forming cavity, which is usually used to manufacture the product cavity and support structure.

[0003] However, in the mold, the plates are usually fixed by bolts or clamping structures. Therefore, the plates are usually in a fixed state and can only play the role of cavity and support for the manufactured product. The use effect of the plates is too simple and cannot assist in product production.

[0004] Therefore, it is necessary to propose a device for quickly changing the angle of internal panels of automobile molds to solve the above problems. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The utility model provides Figure 1 - Figure 5 The device for quickly changing the angle of internal panels of an automobile mold shown in the figure comprises a lower mold 1 and an upper mold 2. Both the upper mold 2 and the lower mold 1 are prior art, and their power is output through a hydraulic press. They are prior art and will not be described in detail here. A support plate 3 is movably provided on the inner side of the upper mold 2, and a pressure rod 101 is fixedly provided at one end of the lower mold 1. The end of the pressure rod 101 abuts against one side of the support plate 3. Through the setting of the pressure rod 101, a mounting hole is directly reserved on the surface of the product. The upper mold 2 is movably arranged above the lower mold 1 through a guide rod. A rotating groove 4 is provided on the inner wall of the upper mold 2. The rotating groove 4 is rectangular. A rotating plate 5 is movably provided on the inner side of the rotating groove 4. Avoidance slopes 14 are provided at the corners of the rotating plate 5 to facilitate the rotation of the rotating plate 5 in the rotating groove 4. One side of the rotating plate 5 is fixedly connected to the other side of the support plate 3, and a lifting block 6 for lifting the rotating plate 5 is fixedly provided on the inner wall of the rotating groove 4.

[0027] Guide grooves 11 are provided on the inner walls on both sides of the rotating groove 4, and rotating shafts 10 are fixed at both ends of the rotating plate 5. The rotating shafts 10 are movably arranged inside the guide grooves 11. The guide grooves 11 are rectangular. Through the setting of the rectangular grooves 11, the rotating plate 5 can move back and forth inside the rotating groove 4 through the rotating shafts 10.

[0028] The inner wall of the rotating groove 4 is provided with two spring grooves 7, a slider 8 is provided inside the spring groove 7, and a compression spring 9 is fixed on the side corresponding to the slider 8 and the spring groove 7. The height of the slider 8 is higher than the height of the avoidance slope 14. Figure 4 As shown;

[0029] By setting the rotating plate 5 and the lifting block 6, after the product is formed, when the upper mold 2 is raised, the support plate 3 is quickly rotated by the angle, and by setting the extrusion spring 9, when the pressure rod 101 is separated from the support plate 3, the spring of the extrusion spring 9 is quickly reset, so that the support plate 3 is quickly rotated, and the product can be taken out immediately, thereby greatly reducing the process time of product production, and automatically demoulding without manual operation by the operator.

[0030] By setting the avoidance slope 14 and the guide groove 11, the rotation range of the support plate 3 is limited when the support plate 3 rotates rapidly. The structure is simple, which prevents the rotating plate 5 from rotating too much, causing the rotating plate 5 to escape from the rotating groove 4. When the rotating plate 5 rotates, the avoidance slope 14 will abut against the inner wall of the rotating groove 4, and the rotating shaft 10 is at the outermost edge of the guide groove 11. The rotation angle of the rotating plate 5 is limited by the rotating shaft 10 and the avoidance slope 14.

[0031] A sealing groove 12 is provided on the inner wall of the upper mold 2, and a sealing rod 13 is fixedly provided on the side of the support plate 3 close to the rotating groove 4. The sealing groove 12 and the sealing rod 13 are both U-shaped, and both ends of the sealing rod 13 are inclined to expand outward. The shape of the sealing groove 12 is the same as that of the sealing rod 13. Through the sealing groove 12 and the sealing rod 13, when the support plate 3 drives the sealing rod 13 to rotate and fit into the sealing groove 12, the support plate 3 seals the gap between the rotating groove 4 and the rotating plate 5 to prevent the rotating groove 4 from affecting the product molding.

[0032] Two transverse grooves 15 are formed on the inner wall of the sealing groove 12 , and a transverse plate 16 is fixed on the inner side of the end of the sealing rod 13 . The transverse plate 16 abuts against the inner wall of the transverse groove 15 , and the cooperation between the transverse plate 16 and the transverse groove 15 assists the connection between the sealing rod 13 and the sealing groove 12 .

[0033] Through the principle of inclined settings at both ends of the sealing groove 12 and the sealing rod 13, and the mutual cooperation between the transverse groove 15 and the sealing rod 13, the supporting plate 3 is attached to the inner wall of the upper mold 2, so that a clamping force is formed between the sealing groove 12 and the sealing rod 13, thereby ensuring the sealing degree while improving the strength of the clamping force.

[0034] Working principle: The operator drives the upper die 2 toward the lower die 1 through the hydraulic press, so that the upper die 2 drives the rotating plate 5 and the support plate 3 to move. At this time, the support plate 3 is set at an angle, so that the pressure rod 101 contacts the support plate 3, so that the pressure rod 101 squeezes the support plate 3 to move, so that the support plate 3 drives the rotating plate 5 to move, so that the rotating plate 5 rotates around the rotating shaft 10, so that the rotating plate 5 and the support plate 3 seal the rotating groove 4;

[0035] At the same time, the support plate 3 drives the sealing rod 13 and the transverse plate 16, so that the sealing rod 13 and the transverse plate 16 enter the sealing groove 12 and the transverse groove 15 respectively, thereby improving the sealing performance of the support plate 3 on the rotating groove 4;

[0036] The upper mold 2 and the lower mold 1 are combined to perform injection molding and product molding operations;

[0037] After the product is formed and cooled, the upper mold 2 is driven to move by the hydraulic press, so that the upper mold 2 is separated from the lower mold 1, and the pressure rod 101 is separated from the support plate 3, so that the support plate 3 is no longer under force, and the slider 8 is squeezed by the extrusion spring 9 to move, so that the slider 8 squeezes the rotating plate 5, so that the rotating plate 5 moves in the rotating groove 4 through the rotating shaft 10 and the guide groove 11. Through the setting of the lifting block 6, one end of the rotating plate 5 is raised, so that the rotating plate 5 drives the support plate 3 to rotate, so as to demold the molded product, and automatically demold the mold by squeezing the spring 9, and it can also automatically prepare for the next work.
