[0001] The utility model relates to the field of stamping dies, in particular to a die provided with a rotating block. Background Art

[0002] Massage is becoming more and more popular as a health care item that can make people happy physically and mentally. In the past, most people went to massage shops for manual massage, but many people could not visit massage shops frequently for massage health care due to time and economic conditions. With the development of technology, the massage function of massage chairs is getting closer and closer to manual massage, and has been recognized by the public.

[0018] (2) In this solution, the H-shaped positioning block arranged between the two sub-plates of the upper template cooperates with the positioning columns arranged around to improve the position accuracy of the connection between the two sub-plates and ensure the quality of the molded product.

[0019] (3) In this solution, the ejector pin limits the displacement of the guide section through the limiting section at the lower end of the T-pin, thereby preventing the lower mold swing block from deforming and affecting the bending accuracy of the fixed plate. The structure is simple and ingenious. The ejector pins arranged on the upper mold base and the lower mold base ensure that the fixed plate is completely separated from the mold after molding, thereby ensuring the demolding effect.

[0032] Example 1

[0033] like Figure 1As shown, this embodiment provides a mold with a rotating block, which is used for forming a fixed plate, including an upper mold base 1 and a lower pad 6 and a lower mold base 3 connected to each other. The mold also includes an upper mold plate 4, a lower mold plate 5, a lower mold swing block 7 and a ejection pin 8; the upper mold plate 4 is fixed on the upper mold base 1, and the shape of the upper mold plate 4 matches the internal shape of the fixed plate, the lower mold plate 5 and the lower pad 6 are fixed on the lower pad 2, one end of the lower mold swing block 7 can be rotatably fixed on the lower mold plate 5, and the other end matches the shape of the bending part of the fixed plate, one end of the ejection pin 8 can be telescopically fixed on the lower mold base 3, and the other end contacts and connects the lower mold swing block 7.

[0034] Working principle: The fixed plate to be formed is placed above the lower die swing block 7. The upper die plate 4 applies pressure to the fixed plate driven by the upper die base 1. As the fixed plate moves downward, the lower die swing block 7 rotates and compresses the ejector pin 8. The upper die plate 4 cooperates with the contour of the lower die swing block 7 to complete the bending of the fixed plate. Then the upper die base 1 drives the upper die plate 4 away from the lower die plate 5, the ejector pin 8 is reset, and the lower die swing block 7 is rotated, so that the formed fixed plate is automatically demolded.

[0035] This solution places the fixed plate to be formed above the lower die swing block 7, and the upper die plate 4 applies pressure to the fixed plate under the drive of the upper die seat 1. As the fixed plate moves downward, the lower die swing block 7 rotates and compresses the ejector pin 8. The upper die plate 4 cooperates with the contour of the lower die swing block 7 to complete the bending of the fixed plate. After that, the upper die seat 1 drives the upper die plate 4 away from the lower die plate 5, and the ejector pin 8 is reset, and the lower die swing block 7 is rotated, so that the formed fixed plate is automatically demolded. The lower die plate 5 rotatably connected to the lower die swing block 7 can be fixed on the lower pad 6, which is convenient to install, and the lower die plate structure is simplified. In combination with the ejector pin 8 that can automatically reset, after the upper die plate 4 is removed, the ejector pin 8 drives the lower die swing block 7 to rotate and pushes the upper fixed plate to be demolded, so that the bent fixed plate can be directly taken out, eliminating the step of separate demolding and improving processing efficiency.

[0038] The H-shaped positioning block arranged between the two sub-plates of the upper template cooperates with the positioning columns arranged around to improve the position accuracy of the connection between the two sub-plates and ensure the quality of the molded product.

The T-pin 82 passes through the lower pad 6. One end of the T-pin 82 is connected to the reset spring 81, and the other end contacts and connects to the lower die swing block 7.

[0041] Furthermore, a fixing groove matching with the reset spring 81 is provided on the lower die base 3, the reset spring 81 is located in the fixing groove, the T-pin 82 includes a guide section and a limit section connected to each other, the diameter of the limit section is larger than the diameter of the wire section, and a guide hole matching with the shape of the guide section is provided on the lower pad 6, the limit section is connected to the reset spring 81, and the guide section contacts and connects to the lower die swing block 7.

[0043] The ejector pin limits the displacement of the guide section through the limiting section at the lower end of the T-pin, avoiding deformation of the lower die swing block and affecting the bending accuracy of the fixed plate. The structure is simple and ingenious. The ejector pins arranged on the upper die base and the lower die base ensure that the fixed plate is completely separated from the die after forming, thereby ensuring the demoulding effect.

When the fixed plate is completed, the two ends of the support plate match the support section 71, and the upper end surface of the support plate fits the lower end of the fixed plate and is flush with the lower end of the bending section 72. Then the upper template 4 is removed, and the support plate is reset under the action of the spring to assist in demolding the formed fixed plate, thereby improving production efficiency and demolding quality.

[0046] Specifically, the upper die base 1 is further provided with an upper pad 9 and an upper support plate 10, one end of the upper pad 9 is connected to the upper die base 1, and the other end is connected to the upper support plate 10, and the number of upper pads 10 is multiple.
