Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a convex hull facade reinforcement mold. Background Art

[0002] As the world pays more and more attention to environmental protection, product design has begun to focus on reducing costs, how to make products lighter, and how to achieve energy conservation and emission reduction in the production process. Taking all these factors into consideration, product design has become more complicated and product processing has become more difficult. Using traditional processing methods, either processing is impossible or the processing procedures are too many and the cost is too high.

[0003] For example, rib-type boss stamping parts or geometric ribs, the structure is similar to Figure 1 As shown, it includes a flat convex edge structure at the bottom, the convex edge is connected to a raised convex bulge, and convex ribs are arranged circumferentially outward in the middle of the convex bulge. This structure can effectively increase the strength of the convex ribs, thereby achieving the effect of reducing product weight and saving raw materials.

[0004] Referring to the invention patent with publication number CN106734816B, it includes a rib-type stamping die. When the rib-type stamping die is used for stamping the rib, the bulge is first buckled on the punch. When the mold is closed, a gap is left on the havers so that the bulge automatically bulges outward to form a rib. Although this design can realize the preparation of the rib on the bulge, there is no structure for extruding the rib on the punch. The bulge is only extruded and deformed outward by the middle part of the bulge. In this way, the controllability of the formed rib structure is weak, which can easily cause the structural instability of the bulge.

[0005] Therefore, it is necessary to provide a technical solution to solve the above problems. Utility Model Content

[0037] In order to more clearly illustrate the technical solution of the utility model, a preferred embodiment is provided below. Figures 1 to 8 , a convex hull facade rib punching mold, comprising an upper mold component 1 and a lower mold component 2, wherein:

[0038] The upper die assembly 1 comprises an upper die base 11, an upper die core 12 and a first driving component 13. A slide groove 111 is provided at the bottom of the upper die base 11. The upper die core 12 is slidably arranged in the slide groove 111. A molding protrusion 121 is provided at the side end of the upper die core 12. The first driving component 13 is installed on the upper die base 11 and is used to drive the upper die core 12 to slide horizontally.

[0039] The lower die assembly 2 includes a lower die base 21 and a lower die core 22 . A molding cavity 211 is disposed on the top of the lower die base 21 . The lower die core 22 is disposed in the molding cavity 211 . A molding groove 221 matching the molding protrusion 121 is disposed on the lower die core 22 .

[0040] Compared with the prior art, the utility model relates to a convex bulge vertical rib die, which is different in that a molding protrusion 121 is provided on the upper die core 12, and a first driving component 13 that can drive the upper die core 12 to move is provided, and a corresponding molding groove 221 is provided on the lower die core 22, so that when the mold is closed, the bulge is placed in the molding cavity 211, and the upper die core 12 enters the molding cavity 211 as the upper die seat 11 moves downward, and is located on the inner side of the bulge, when the first driving component 13 drives the upper die core 12 to move outward, the convex rib structure can be punched out on the bulge through the cooperation of the molding protrusion 121 and the molding groove 221. The design of the present application allows the convex rib structure to be stamped and extruded by the cooperation of the molding protrusion 121 and the molding groove 221, so that the molded convex rib structure is highly controllable, thereby effectively improving the quality and yield rate of the bulge after molding.

[0041] In this embodiment, the upper die core 12 includes a sliding portion 122 and a forming portion 123 connected to each other, the sliding portion 122 is slidably connected in the slide groove 111, the forming portion 123 is located below the sliding portion 122, and the forming protrusion 121 is provided on the forming portion 123. Furthermore, a lubrication groove 124 is provided on the outer side of the sliding portion 122. In practical applications, the sliding portion 122 is slidably matched with the upper die seat 11, so that the forming portion 123 protrudes into the convex bulge, thereby cooperating with the forming groove 221 to form a convex rib on the bulge, and the lubrication groove 124 is used to fill the lubricating liquid, thereby reducing the friction loss generated between the sliding portion 122 and the upper die seat 11 when sliding, thereby improving the service life.

[0042] In this embodiment, the first driving component 13 includes a first guide column 131 and a first reset elastic member 132; the first guide column 131 is fixedly connected to the upper mold base 11, and a first cone is provided at the bottom thereof, and the first cone is arranged in the slide groove 111. The slide groove 111 has an inclined surface on the side away from the first cone, and the upper mold core 12 is in contact with the first cone and the inclined surface; one end of the first reset elastic member 132 is fixedly connected to the upper mold base 11, and the other end thereof is in contact with the top surface of the lower mold core 22.

[0043] Specifically, in the mold opening state, the lower mold core 22 moves to the lowest point due to the elastic force of the first reset elastic member 132. At this time, the molding protrusion 121 on the lower mold core 22 is located correspondingly on the inner side of the molding cavity 211 in the vertical direction, and then when the mold is closed, the molding protrusion 121 can smoothly enter the molding cavity 211; and in the mold closing process, the upper mold core 12 moves downward with the upper mold base 11 until it touches the lower mold base 21 or the lower mold core 22, and then stops moving in the vertical direction, while the upper mold base 11 will continue to move downward. At this time, the upper mold core 12 gradually overcomes the elastic force applied by the first reset elastic member 132. Under the guidance of the inclined surface and the first cone, the upper mold core 12 will produce an oblique upward movement relative to the upper mold base 11, and relative to the lower mold base 21, the upper mold core 12 actually only performs a horizontal transverse movement, so that the molding protrusion 121 can gradually approach the molding groove 221, thereby punching out a convex rib on the convex bump.

[0044] In this embodiment, a second guide column 23 is installed on the lower mold base 21. The second guide column 23 is located in the molding cavity 211 and corresponds to the position of the first guide column 131. A second cone is provided on the top of the second guide column 23. The lower mold base 21 is also provided with a third driving component 24 for driving the second guide column 23 to lift and lower. A guide notch is provided at the bottom of the lower mold core 22 at the position corresponding to the second guide column 23.

[0045] Furthermore, the third driving component 24 includes a lifting block 241, a slider 242, a shovel base 243 and a third reset elastic member 244; the lifting block 241 is connected to the lower mold base 21 in a manner that allows it to be lifted and slid, and a first inclined surface is provided at its end, and the second guide column 23 is installed on the lower mold base 21; the slider 242 is connected to the lower mold base 21 in a manner that allows it to be horizontally slidable, and a second inclined surface is provided at one end thereof close to the lifting block 241 and matched with the first inclined surface, and a third inclined surface is provided at one end thereof away from the lifting block 241; the shovel base 243 is installed on the upper mold base 11, and its position corresponds to that of the slider 242, and a fourth inclined surface is provided at its bottom and matched with the third inclined surface; one end of the third reset elastic member 244 is connected to the lower mold base 21, and the other end is connected to the slider 242.

[0046] In actual application, the upper mold core 12 is supported by the second guide column 23 to prevent the upper mold core 12 from applying too much pressure and damaging or wearing the workpiece. Specifically, in the mold open state, the shovel base 243 and the slider 242 do not touch each other, and then the third reset elastic member 244 drives the slider 242 away from the lifting block 241. At this time, the lifting block 241 is at the lowest point, and the second guide column 23 is also at the lowest point, so as to ensure that when the mold is closed, the upper mold core 12 can be smoothly placed in the molding cavity 211 first; during the mold closing process, the upper mold core 12 is first placed in the molding cavity 211, and when it slides obliquely relative to the upper mold base 11, the shovel base 243 The third inclined surface starts to contact with the fourth inclined surface synchronously. As the upper die seat 11 moves downward, the shovel base 243 drives the slider 242 to gradually move horizontally. Under the cooperation of the first inclined surface and the second inclined surface, the lifting block 241 drives the slider 242 to produce an upward movement, and the second guide column 23 rises with the lifting block 241, thereby applying an oblique lifting force to the upper die core 12. Through the cooperation of the second guide column 23 and the first guide column 131, the upper die core 12 moves obliquely smoothly to punch out the convex rib. With the above design, when the upper die core 12 moves horizontally relative to the lower die seat 21, it is subjected to the lifting force of the second guide column 23, and the pressure and friction acting on the workpiece are greatly reduced, so that the risk of damage to the workpiece can be effectively reduced.

[0047] In this embodiment, a fixing block 245 is installed on the lower die base 21, and a receiving groove is provided on the fixing block 245, and the receiving groove is located above the slider 242; the third resetting elastic member 244 is arranged in the receiving groove, and one end of the third resetting elastic member 244 is connected to the fixing block 245, and the other end is connected to the slider 242. It should be understood that in order to prevent the slider 242 from wearing too quickly, the bottom and side of the slider 242 need to be provided with a wear-resistant block 246, and the present application sets the third resetting elastic member 244 above the slider 242 to avoid the wear-resistant block 246, thereby reducing the required width of the slider 242, making the structure more suitable for progressive dies.

[0048] In this embodiment, a plurality of lower mold cores 22 are provided, and the plurality of lower mold cores 22 are arranged in a circular array on the outer periphery of the first guide column 131. With the above design, a plurality of convex ribs can be formed on the convex bump at one time.

[0049] In this embodiment, a plurality of lower mold cores 22 are provided, and the plurality of lower mold cores 22 are all disposed in the molding cavity 211 and arranged in a circular array outside the second guide column 23, and all are connected to the lower mold base 21 for oblique sliding movement; a second reset elastic member 25 is installed on the lower mold base 21, and the second reset elastic member 25 is located below the lower mold core 22, and is used to apply thrust to the lower mold core 22. It should be understood that the elastic force of the second reset elastic member 25 is smaller than the elastic force of the first reset elastic member 132. Specifically, in the mold opening state, the lower mold core 22 is moved obliquely to the highest point by the elastic force of the second reset elastic member 25. At this time, the lower mold cores 22 are away from each other, and the diameter of the cavity surrounded by the multiple lower mold cores 22 reaches the maximum. In the mold closing process, the convex bulge is first placed in the cavity surrounded by the multiple lower mold cores 22, and the upper mold core 12 gradually moves downward until it contacts and presses down the corresponding lower mold core 22, so that the multiple lower mold cores 22 gradually move inward, thereby closing the positioning convex bulge. The above design can prevent the outer wall of the convex bulge from being damaged by friction with the lower mold core 22 when it is placed in the cavity.

[0050] In this embodiment, a lifting plate 26 is provided above the lower die seat 21, and the lifting plate 26 and the lower die seat 21 are connected by a fourth reset elastic member, and a guide groove 261 is provided on the top of the lifting plate 26; a stripping plate 14 is installed at the bottom of the upper die seat 11, and a positioning column is provided at the bottom of the stripping plate 14. The convex bulge vertical rib mold involved in this application is a progressive die, and in actual application, the material strip is supported by the lifting plate 26, and the side end of the material strip is located in the guide groove 261 of the lifting plate 26. Each time the mold is closed or opened, the progressive feeding mechanism on the mold will drive the material strip to move one station, and the next time the mold is closed, the stripping plate 14 will go down with the upper die seat 11, and cooperate with the hole position on the material strip through the positioning column to position the material strip, and the stripping plate 14 will press the lifting plate 26 downward during the downward process until the bulge on the material strip enters the molding cavity 211, so as to perform the stamping work.

[0051] The above description is only a preferred embodiment of the present invention, and its structure is not limited to the shapes listed above. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
