DETAILED DESCRIPTION
[0024] The following will be described in detail in combination with the accompanying Figures 1-5 The present application is further described in detail.
[0025] A stainless steel thin-wall part curved surface texture preparation upper mold structure, referring to Figure 1 The upper mold structure 1 is used for cooperating with the lower mold structure 2, and the recess point texture on the surface of the stainless steel thin-wall part is machined through the cooperation of the upper mold structure 1 and the lower mold structure 2.
[0026] The lower mold structure 2 includes a lower mold base 21, a lower mold plate 22 fixedly mounted on the lower mold base 21, and a lower mold core 23 fixedly mounted on the lower mold plate 22. The lower mold core 23 is vertically mounted on the lower mold plate 22 and is used for mounting and inserting thin-walled stainless steel parts. The outer wall of the lower mold core 23 is provided with a concave textured surface 24. The lower mold core 23 is adapted to the shape of the thin-walled stainless steel part. The upper end of the lower mold core 23 is provided with a circular curved surface, and the concave textured surfaces 24 are also distributed on the circular curved surface.
[0027] Reference Figure 2 and Figure 3 As shown, the upper mold structure 1 includes an upper mold base 101 , an upper mold pad 102 , an upper mold main forming block 103 , an upper mold driving base 104 and an upper mold plate 105 .
[0028] The upper die pad 102 is fixed on the upper die base 101, and the upper die driving base 104 is fixedly installed on the upper die pad 102. A cavity for accommodating the upper die main forming block 103 is formed in the upper die driving base 104. The upper die plate 105 is located below the upper die driving base 104. Connecting rods 106 are fixedly provided on both sides of the upper die plate 105. The upper end of the connecting rod 106 is slidably inserted in the upper die pad 102. The upper end of the connecting rod 106 is provided with an anti-slip block, so that the upper die plate 105 is suspended on the upper die pad 102.
[0029] The upper mold main forming block 103 is slidably mounted on the upper mold plate 105. Specifically, a sliding groove is provided on the upper mold plate 105, and a sliding block is provided at the bottom of the upper mold main forming block 103 to cooperate with the sliding groove. Several upper mold main forming blocks 103 are arranged along the circumference, and these blocks 103 enclose a part cavity 107. In one embodiment, there are six upper mold main forming blocks 103, arranged circumferentially. The inner wall of each upper mold main forming block 103 is provided with a convex textured surface 108. When the six upper mold main forming blocks 103 are enclosed, the six convex textured surfaces 108 form a complete circle.
[0030] It is worth noting that the stainless steel thin-walled part is a condom mold, and therefore has a cylindrical main body and a convex hull disposed at the upper end of the main body, the convex hull and the main body being connected by a curved surface. The convex textured surface 108, which forms a full circle, is used to form the main body of the stainless steel thin-walled part.
[0031] The upper mold main forming block 103 is capable of sliding radially along the upper mold plate 105. The upper mold drive seat 104 cooperates with the outer wall of the upper mold main forming block 103 to drive the upper mold main forming block 103 to slide and retract. This movement of the upper mold drive seat 104 allows the convex textured surface 108 of the upper mold main forming block 103 to enclose a full circle to accommodate the main shape of the thin-walled stainless steel part. The outer wall of the upper mold main forming block 103 is formed into a first inclined surface 109, and the upper mold drive seat 104 is provided with a second inclined surface 110 that mates with the first inclined surface 109.
[0032] Therefore, when the upper template 105 abuts against the lower template 22 of the lower mold structure 2, it is connected to the upper mold base 101 through a hydraulic press, which can drive the upper mold driving base 104 to move up and down, and then the upper mold driving base 104 can realize the contraction of the upper mold main forming block 103 to press the convex texture surface 108 against the outer wall of the main body of the stainless steel thin-walled part.
[0033] Reference Figure 4 and Figure 5 As shown, the upper part of the main body in this application is a curved surface, and the concave texture needs to be processed on the curved surface. If the concave points are directly molded out with horizontal force, the concave texture on the curved surface will be deformed. Therefore, the concave texture on the curved surface needs to be molded with force in the normal direction of the curved surface.
[0034] An upper mold guide rail 111 is fixed on the upper mold pad 102 , and an upper mold curved surface forming block 112 is obliquely and slidably mounted on the upper mold guide rail 111 . The oblique sliding direction of the upper mold curved surface forming block 112 is perpendicular to the normal direction of the curved surface. The number of upper mold guide rails 111 and upper mold curved surface forming blocks 112 is the same as the number of upper mold main forming blocks 103. There are six upper mold guide rails 111 and upper mold curved surface forming blocks 112 along the circumferential direction. The arrangement position of the upper mold curved surface forming block 112 corresponds one-to-one to the upper mold main forming block 103. The upper mold curved surface forming block 112 is arranged above the upper mold main forming block 103. The lower surface of the upper mold curved surface forming block 112 is adapted to the upper surface of the upper mold main forming block 103. The lower surface of the upper mold curved surface forming block 112 and the upper surface of the upper mold main forming block 103 are both inclined, and the inclination direction is the same as the sliding direction of the upper mold curved surface forming block 112. A molding gap is formed between the upper mold curved surface forming block 112 and the upper mold main forming block 103.
[0035] A driving spring 113 is arranged between the upper mold main forming block 103 and the upper mold curved surface forming block 112, that is, an upper spring groove is provided on the upper surface of the upper mold main forming block 103, and a lower spring groove is provided on the lower surface of the upper mold curved surface forming block 112. The driving spring 113 is arranged in the vertical direction, and the two ends of the driving spring 113 are respectively fixed in the upper spring groove and the lower spring groove.
[0036] One end of the upper mold curved forming block 112 is provided with a convex texture curved surface 114 facing the part cavity 107. The upper mold main forming block 103 is provided with a pushing part matched with the other end of the upper mold curved forming block 112. In one embodiment, the pushing part includes a pushing block 115 provided on the upper end of the upper mold main forming block 103, and the pushing block 115 is provided with a first pushing inclined surface 116. The other end of the upper mold curved forming block 112 is provided with a second pushing inclined surface 117 matched with the first pushing inclined surface 116.
[0037] When the upper mold main forming block 103 is slidably contracted by the upper mold driving seat 104, the upper mold curved forming block 112 will be driven to contract by the pushing part. All the convex texture curved surfaces 114 on the upper mold curved forming block 112 will be enclosed to form a complete circle and press against the curved surface part of the stainless steel thin-wall part.
[0038] It is worth noting that when the lower mold core 23 is located in the part cavity 107, the concave texture on the lower mold core 23 corresponds to the convex texture in the part cavity 107 and the texture position on the convex texture convex surface.
[0039] The upper mold gasket 102 is fixed with a limiting column 118 in the vertical direction. The lower end of the limiting column 118 extends into the part cavity 107. The lower end of the limiting column 118 is provided with a part receiving groove 119 in the middle part, which is used to accommodate the convex hull on the upper end of the stainless steel thin-wall part, thereby improving the installation stability of the stainless steel thin-wall part in the part cavity 107. The lower end of the limiting column 118 blocks the sliding path of the upper mold curved forming block 112, and the limiting column 118 can limit the excessive sliding of the upper mold curved forming block 112.
[0040] Therefore, by placing the stainless steel thin-wall part on the lower mold core 23, the stainless steel thin-wall part is placed into the part cavity 107. At this time, the upper mold structure 1 and the lower mold structure 2 are clamped, the upper mold plate 105 abuts against the lower mold plate 22, and the upper mold driving seat 104 moves downward to drive the upper mold main forming block 103 to slide and contract. When the upper mold main forming block 103 slides and contracts, the upper mold curved forming block 112 will slide and contract through the pushing part. Therefore, the upper mold main forming block 103 will press against the main part of the stainless steel thin-wall part, and the upper mold curved forming block 112 will press against the curved surface part of the stainless steel thin-wall part. In turn, the convex texture surface 108 of the upper mold main forming block and the convex texture curved surface 114 of the upper mold curved forming block 112 realize the processing and forming of the concave point texture of the stainless steel thin-wall part.
[0041] The upper mold structure 1 can form the concave point texture on the stainless steel thin-wall part at one time, has high production efficiency, and the concave point texture on the curved surface of the stainless steel thin-wall part is uniform in depth and size, and the product yield is high.
[0042] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
