Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a wing-shaped part mold. Background Technology

[0002] Wing-shaped part molds are precision forming tools designed specifically for manufacturing wing-shaped parts with complex curved surfaces and thin-walled structures. They are widely used in aerospace, automotive manufacturing, and high-end equipment industries. Their core structure includes a punch, die, positioning system, and guiding device, made of high-strength alloy steel or composite materials to ensure dimensional stability and wear resistance under high pressure and high temperature conditions. The mold design relies on CAD / CAE technology, optimizing the surface structure through 3D modeling and metal flow simulation. This allows for precise control of the part's wall thickness uniformity and surface transition accuracy, reducing subsequent machining allowances. Addressing the issue of deformation in thin-walled parts, the mold integrates a multi-stage ejection mechanism and a local lubrication system, effectively reducing demolding resistance and friction loss. Furthermore, the modular design supports rapid mold changes and process adjustments. Combined with an intelligent temperature control system, it can adapt to the forming requirements of different materials, significantly improving production efficiency and part quality. It is a key piece of equipment for achieving lightweight and high-precision goals in high-end manufacturing.

[0003] However, with existing wing-shaped part molds, if ejection is not timely, the part will have an excessively long cooling time in the mold cavity, increasing the adhesion force with the mold and greatly increasing the resistance during demolding. This may not only cause the part to deform and crack, but also aggravate the wear of the mold cavity and reduce the service life of the mold. Therefore, we need a wing-shaped part mold. Utility Model Content

[0020] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model embodiment provides a wing-shaped part mold, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the system includes an upper mold 1, a molding component 3 fixedly connected inside the upper mold 1, a lower mold 2 fixedly connected to the bottom of the molding component 3, a springback component 4 disposed inside the lower mold 2, an injection hole 5 opened at the top of the upper mold 1, the molding component 3 includes a punch 301, and the punch 301 is fixedly connected inside the upper mold 1, a glue inlet 302 opened at the bottom of the punch 301, a protrusion 303 fixedly connected to the bottom of the punch 301, a positioning pin 304 fixedly connected to the bottom of the punch 301, and the outer wall of the positioning pin 304 is movably connected to... A positioning groove 305 is provided on the top of the cavity mold 306. The top of the cavity mold 306 has a groove 307. The upper mold 1 drives the punch 301 to move downward, so that the punch 301 drives the four protrusions 303 and the six positioning pins 304 to move downward, so that the four protrusions 303 and the six positioning pins 304 respectively engage with the four grooves 307 and the six positioning grooves 305, thereby completing the fixation of the mold cavity. At this time, injection molding can be performed through the injection hole 5, and then the mold cavity is filled through the two injection holes 302.

[0023] Furthermore, such as Figure 2 and Figure 3 As shown, the punch 301 forms a locking structure with the die 306 through the protrusion 303, and the shape and size of the protrusion 303 match the shape and size of the groove 307. The outer wall of the protrusion 303 is fitted to the inner wall of the groove 307. Through the protrusion 303, the protrusion 303 can lock the die 306 with the fixed position of the punch 301, which is beneficial to the better forming of the part.

[0024] Furthermore, such as Figure 2 and Figure 3 As shown, the punch 301 and the die 306 form a locking structure through the positioning pin 304. The shape and size of the positioning pin 304 match the shape and size of the positioning groove 305, and the outer wall of the positioning pin 304 fits against the inner wall of the positioning groove 305. Through the positioning pin 304, the positioning pin 304 can lock the die 306 with the fixing of the punch 301, which is beneficial to the better forming of the part.

[0025] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the springback assembly 4 includes a fixing hole 401, which is located at the bottom of the upper mold 1. A movable column 402 is movably connected to the inner wall of the fixing hole 401. A movable plate 403 is fixedly connected to the bottom of the movable column 402. An ejector pin 404 is fixedly connected to the top of the movable plate 403. A spring 405 is fixedly connected to the bottom of the movable plate 403. A support plate 406 is fixedly connected to one end of the spring 405. By moving the upper mold 1 upward, the pressure of the upper mold 1 on the four movable columns 402 is released, and the pressure of the four movable columns 402 on the movable plate 403 is released. This releases the compression of the four springs 405 caused by the squeezing of the movable plate 403, allowing the four springs 405 to elastically reset and drive the movable plate 403 to move upward. This causes the movable plate 403 to drive the six ejector pins 404 to move upward, causing the ejector pins 404 to push out the part, thus completing the demolding of the part.

[0026] Furthermore, such as Figure 3 and Figure 4 As shown, the movable column 402 forms a fixed structure with the ejector pin 404 through the movable plate 403, and the bottom of the movable column 402 is fixed to the top of the movable plate 403, and the bottom of the ejector pin 404 is fixed to the top of the movable plate 403. Through the movable plate 403, the movable plate 403 can fix the ejector pin 404 with the support of the movable column 402, which enhances the effect of fixing the ejector pin 404.

[0027] Furthermore, such as Figure 4 As shown, the movable column 402 forms an elastic structure with the movable plate 403 and the spring 405. The top of the movable plate 403 is fixed to the bottom of the movable column 402, and the bottom of the movable plate 403 is fixed to one end of the spring 405. With the movable plate 403, the movable plate 403 can support the movable column 402 with the support of the spring 405, which facilitates the extension and retraction of the movable column 402.

[0028] Furthermore, such as Figure 4 As shown, the movable plate 403 forms an elastic structure with the support plate 406 via the spring 405. One end of the spring 405 is fixed to the bottom of the movable plate 403, and the other end of the spring 405 is fixed to the top of the support plate 406. With the spring 405, the movable plate 403 can be supported by the support plate 406, which facilitates the extension and retraction of the movable plate 403.

[0029] Working principle: During use, the upper mold 1 and the lower mold 2 are closed. At this time, the upper mold 1 drives the punch 301 to move downward, which in turn drives the four protrusions 303 and the six positioning pins 304 to move downward. This allows the four protrusions 303 and the six positioning pins 304 to engage with the four grooves 307 and the six positioning slots 305 respectively, thereby fixing the mold cavity. At this time, injection molding can be performed through the injection hole 5, and then the mold cavity can be filled through the two injection holes 302. After the part cools and solidifies, when demolding is required, the upper mold 1 can be moved upward, which releases the pressure of the upper mold 1 on the four movable pins 402, and releases the pressure of the four movable pins 402 on the movable plate 403. This releases the compression of the four springs 405 caused by the squeezing of the movable plate 403, allowing the four springs 405 to elastically reset and drive the movable plate 403 to move upward. The movable plate 403 then drives the six ejector pins 404 to move upward, causing the ejector pins 404 to push the part out, thus completing the demolding of the part.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
