Description

Technical Field

[0001] This utility model belongs to the field of rolling die technology, and in particular relates to a non-ferrous metal rolling forming die. Background Technology

[0002] Non-ferrous metals refer to metallic materials other than ferrous metals such as iron, chromium, and manganese. They can be deformed into workpieces of specific shapes by using rolling dies and external forces such as rolling and extrusion to meet different application requirements.

[0003] Currently, rolled metal workpieces need to be cooled inside the mold core after forming before they can be removed. During this period, the mold is occupied and rolling operations cannot continue, resulting in low overall production efficiency. Furthermore, the method of cooling the entire mold together also prolongs the cooling time.

[0004] To address the aforementioned problems, this application proposes a non-ferrous metal rolling die. Utility Model Content

[0005] The purpose of this invention is to provide a non-ferrous metal rolling forming die, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a non-ferrous metal rolling forming mold, including a lower mold base and an upper mold base, with a rolling part installed below the upper mold base;

[0008] The mold core is located in a square groove on the lower mold base. A base plate is provided inside the mold core near the lower end. A boss is fixed on the outer side of the lower end of the upper mold base. An electric telescopic unit is installed through the cavity opened inside the boss.

[0009] The mold core has an internal cavity, the lower end of which extends outward to form an expansion cavity, and the upper end of the expansion cavity is provided with a bevel connected to the internal cavity.

[0010] Preferably, the lower mold base is provided with an upwardly extending support rod that passes through a positioning hole at the bottom of the mold core.

[0011] Preferably, the base plate is lifted by the support rod to the height of the inclined side.

[0012] Preferably, the lower end of the base plate is fixed with a protruding ring that engages with the support rod.

[0013] Preferably, the bottom of the mold core has an air hole along its inner edge, with the opening corresponding to the inclined side.

[0014] Preferably, the base plate can be moved down into the expansion cavity after the mold core is removed.

[0015] Preferably, the bottom edge of the convex ring has a uniform concave-convex structure.

[0016] This utility model has the following beneficial effects:

[0017] This utility model uses a separate structure for the die core and the lower die base. After the calendering operation, the die core is taken out upward with the upper die base, and then the die core can be pushed down by an electric telescopic unit to separate it. Then, another die core can be directly replaced into the lower die base for the calendering operation.

[0018] In addition, by moving the base plate down into the interior of the expansion cavity, external air can enter between the base plate and the workpiece through the air holes and the bevel, thereby creating a dual-zone cooling effect, shortening the cooling time and ensuring cooling uniformity.

[0019] After the die core is replaced, the lower die holder does not participate in the cooling process and continues to perform rolling operations, thereby avoiding a large loss of internal heat. This makes it suitable for continuous rolling operations and also avoids the frequent thermal expansion and contraction of the lower die holder, reducing its failure rate.

[0020] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0033] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0034] Please see Figure 1-4 As shown, this utility model is a non-ferrous metal rolling forming mold, including a lower mold base 11 and an upper mold base 12, with a rolling part 121 installed below the upper mold base 12;

[0035] The mold core 13 is located in a square groove on the lower mold base 11. With this separation structure, the calendering part 121 can be directly pulled out of the mold core 13 by friction when it is removed. The mold core 13 has a base plate 131 near the lower end. The upper mold base 12 has a boss 122 fixed on the lower outer side. An electric telescopic unit 1222 is installed through the cavity 1221 inside it. After the mold core 13 is pulled out, the mold core 13 can be pushed out by pushing the plate extending from the upper outer side. At this time, it can be directly transferred to the cooling area by the transfer mechanism.

[0036] The mold core 13 has an inner cavity 132 inside, and the inner wall is in contact with the outer edge of the base plate 131. The lower end of the inner cavity 132 extends outward to form an expansion cavity 1321. The upper end of the expansion cavity 1321 is provided with a bevel 1322 connected to the inner cavity 132. When the base plate 131 is at the height of the bevel 1322, the upper surface is inside the inner cavity 132, so as to perform rolling operation. When the base plate 131 is inside the expansion cavity 1321, the base plate 131 and the lower surface of the workpiece form a cavity to promote cooling.

[0037] Furthermore, the lower mold base 11 is provided with an upwardly extending support rod 111 that passes through the positioning hole 134 at the bottom of the mold core 13. The support rod 111 located inside the lower mold base 11 is used to position the height of the base plate 131. The base plate 131 can also be pushed upward by using the support rod 111 alone in the cooling area instead of the ejector rod, thereby achieving the effect of demolding the workpiece.

[0038] Furthermore, the base plate 131 is lifted by the support rod 111 to the height of the inclined side 1322. The lower end of the base plate 131 is fixed with a protruding ring 1311 that connects to the support rod 111. The support rod 111 is divided into two groups, front and back, and each group is arranged horizontally at equal intervals.

[0039] Furthermore, the bottom of the mold core 13 is provided with an air hole 133 along the inner edge, with the opening corresponding to the inclined side 1322. After the mold core 13 is removed, the bottom plate 131 can be moved down into the interior of the expansion cavity 1321. The bottom edge of the convex ring 1311 has a uniform concave-convex structure, which allows the air hole 133 and the positioning hole 134 to input external air into the interior of the mold core 13, thereby forming a cooling treatment from the inside to the outside on the workpiece in the bottom area of ​​the mold core 13.

[0040] It is understandable that this utility model can promptly separate the mold core 13 for replacement after casting operations, adapting to continuous casting production, while also allowing external air to enter the internal bottom area of ​​the separation mold core 13, thereby implementing cooling treatment on the workpiece from the inside out.

[0041] A specific application of the operation process in this embodiment is as follows: After the workpiece is cast, when it moves out of the rolling section 121 using its frictional resistance, the mold core 13 moves upward and detaches from the lower mold base 11. Then, under the action of the electric telescopic unit 1222, it is pushed downward and can be directly transferred to the cooling area for cooling treatment via the transfer mechanism. At this time, the lower mold base 11 can directly install another mold core 13 for the next set of casting operations. The mold core 13 in the cooling area uses the inclined edge 1322 to connect the expansion cavity 1321 and the inner cavity 132. It can be directly driven by the negative pressure machine to lower the base plate 131 into the interior of the expansion cavity 1321. At this time, the external air enters the expansion cavity 1321 through the air hole 133 and enters between the base plate 131 and the workpiece under the guidance of the inclined edge 1322, thereby achieving cooling treatment from the inside out. This can shorten the overall cooling time, improve the utilization rate of the mold core 13, and ensure the cooling uniformity of different positions of the workpiece.
