[0024] Example

[0025] See also Figure 1-Figure 5 The utility model provides a demoulding assembly, including an injection mold 10 and a hanger assembly 20.

[0026] The injection mold 10 is used for injection molding automobile parts, and the hanger assembly 20 drives the ejector rod 150 to move upward synchronously when the upper mold 120 is opened upward to realize part demoulding.

[0027] See also Figure 1-Figure 4The injection mold 10 includes a lower mold 110, an upper mold 120, a support plate 140 and a push rod 150. The lower mold 110 is located below the upper mold 120, and a mounting groove 130 is provided inside the lower mold 110. The support plate 140 is located inside the mounting groove 130, and the push rod 150 is arranged on the top of the support plate 140 by bolts. The hanger assembly 20 includes a lower vertical plate 210, an upper vertical plate 220 and a connecting portion 250. The bottom end of the lower vertical plate 210 is fixedly connected to the support plate 140, and the top end of the upper vertical plate 220 is fixedly connected to the upper mold 120. The upper vertical plate 220 and the upper mold 120 and the lower vertical plate 210 and the lower mold 110 are fixed by fixing bolts 290. The sides of the lower vertical plate 210 and the upper vertical plate 220 are both provided with strip grooves 230, and the connecting portion 250 slides inside the strip grooves 230 to connect the lower vertical plate 210 and the upper vertical plate 220.

[0028] The lower mold 110 and the upper mold 120 in the injection mold 10 cooperate to produce automobile parts by injection molding. After the injection molding of the parts product is completed, the hydraulic cylinder drives the upper mold 120 to move upward, and the upper mold 120 moves upward while driving the upper vertical plate 220 to move upward synchronously, and the upper vertical plate 220 drives the lower vertical plate 210, the support plate 140 and the ejector 150 to move upward through the connecting part 250. The ejector 150 moving upward can complete the demoulding of the finished product synchronously while the upper mold 120 moves upward, which can not only improve the demoulding efficiency, but also does not require additional power equipment output for the ejector 150 to move upward.

[0029] For specific settings, see Figure 3 The injection mold 10 further includes an elastic part 160, which is connected to the top of the support plate 140 and the top wall of the mounting groove 130. The elastic part 160 includes a guide rod 161 and a spring 162. The top of the guide rod 161 is fixedly arranged on the top wall of the mounting groove 130, and the bottom of the guide rod 161 is movable through the support plate 140 and connected to the bottom wall of the mounting groove 130. The spring 162 is located above the support plate 140 and sleeved on the outside of the guide rod 161. The spring 162 in the elastic part 160 is used to buffer the ejector rod 150 to slowly move upward to eject the product and complete demoulding.

[0030] In the above specific implementation, please refer to Figure 4 and Figure 5, the connection parts 250 are arranged in two groups, and both groups of connection parts 250 are arranged inside the strip groove 230. One group of connection parts 250 is fixedly arranged on the top of the lower vertical plate 210, and the other end of the connection part 250 is slidably arranged on the strip groove 230 on one side of the upper vertical plate 220, and the other group of connection parts 250 is slidably arranged inside the strip groove 230, and a connecting rod 270 is arranged outside the other group of connection parts 250, and an adjusting bolt 260 is arranged on the connecting rod 270, and a threaded hole 280 matching with the adjusting bolt 260 is arranged on the outer side of the upper vertical plate 220. The arrangement of multiple groups of threaded holes 280 can be matched and fixed with the adjusting bolt 260, that is, the height of the upper mold 120 movement and the relative height between the upward movement of the ejector rod 150 can be adjusted by fixing the other group of connection parts 250, and it can be used in conjunction with a variety of mold demoulding.

[0031] For further information, see Figure 5 The connecting portion 250 includes a first limit block 251, a second limit block 252 and a limit rod 253. The limit rod 253 connects the first limit block 251 and the second limit block 252 by welding. The first limit block 251 and the second limit block 252 are respectively slidably disposed in the strip grooves 230 on the sides of the upper vertical plate 220 and the lower vertical plate 210, and the end of the connecting rod 270 is fixedly disposed with the first limit block 251 by welding.

[0032] The present application also provides an automobile parts production mold, including the demoulding component described above.

[0033] The working principle of the demoulding assembly and the automobile parts production mold: When in use, the lower mold 110 and the upper mold 120 in the injection mold 10 are used to produce automobile parts by injection molding. After the injection molding of the parts product is completed, the hydraulic cylinder drives the upper mold 120 to move upward, and the upper mold 120 moves upward while driving the upper vertical plate 220 to move upward synchronously, and the upper vertical plate 220 drives the lower vertical plate 210, the support plate 140 and the ejector 150 to move upward through the connecting part 250. The ejector 150 that moves upward can complete the demoulding of the finished product synchronously while the upper mold 120 moves upward, which can not only improve the demoulding efficiency, but also does not require additional power equipment output for the ejector 150 to move upward.

[0034] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
