Description

Technical Field

[0001] This utility model relates to the field of product molding technology, specifically to a composite mold that integrates the molding functions of ring and cylindrical products. Background Technology

[0002] As the semiconductor packaging industry develops towards miniaturization, high density, and high power, the product structure of chip packaging is constantly being innovated, resulting in two product structures: ring and cylindrical, for different packaging application scenarios.

[0003] Both ring-shaped and cylindrical products are formed by stamping dies, but in the current production process, these two types of products are stamped using their respective dies.

[0004] A prior art patent with publication number CN204320912U discloses a solution comprising an upper mold base, a lower mold base, an upper mold seat, a lower mold seat, a punch fixing plate, a stripper plate, a concave mold plate, an inner guide post, an outer guide post, an upper mold guide sleeve, an upper punch, and an ejector block. The concave mold plate has a concave mold insert inside its inner hole, and an ejector block at its bottom end. The inner hole of the concave mold insert has, from top to bottom, a large cylindrical internal gear ring segment, a conical internal gear ring segment, and a lower cylindrical internal gear ring segment. The lower end of the upper punch has an outer cylindrical tooth punch that mates with the large cylindrical internal gear ring segment. The upper end of the ejector block has an upper cylindrical tooth top that mates with the lower cylindrical internal gear ring segment. This design has advantages such as simple structure, convenient processing, low equipment cost, fewer processes, high work efficiency, and high processing accuracy.

[0005] As existing devices are used, the shortcomings of this technology have gradually become apparent, mainly in the following aspects:

[0006] First, during the production of Ring-shaped products, the material inside the frame becomes waste after stamping and cannot be recycled, which leads to material waste and low material utilization.

[0007] Secondly, cylindrical products are smaller in size, usually not exceeding 10*10mm. The thickness of the product is basically the same as that of the ring-shaped product, but it also needs to be produced using a special mold.

[0008] As can be seen from the above, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides a composite mold that integrates the forming functions of ring and cylindrical products. This solves the problem that in traditional technologies, ring and cylindrical products become waste materials after stamping and cannot be recycled, resulting in material waste and requiring two sets of dedicated molds for production.

[0010] To achieve the above objectives, the present invention provides the following technical solution.

[0011] A composite mold integrating the forming functions of ring and cylindrical products includes a punch template and a die template arranged side by side from top to bottom, and a material feed area is formed through the area between the punch template and the die template. The punch template is arranged vertically and raised and lowered. The die template is provided with a cylindrical die core and an annular die core in sequence along the feeding direction of the material core. The punch template is provided with a cylindrical punch core and an annular punch core that match the cylindrical die core and the annular die core.

[0012] As an optimized solution, the punch template is fixed on the punch base.

[0013] As an optimized solution, a punch pad is fixed between the upper surface of the punch template and the lower surface of the punch base.

[0014] As an optimized solution, the die template is fixed on the die base.

[0015] As an optimized solution, a die pad is fixed between the lower surface of the die template and the upper surface of the die base.

[0016] As an optimized solution, a guide sleeve is vertically fixed to the lower surface of the punch holder, and a guide post inserted into the guide sleeve is vertically fixed to the upper surface of the die holder.

[0017] As an optimized solution, four guide sleeves and four guide posts are provided, and they are located near the four corners of the punch mold base and the die mold base, respectively.

[0018] As an optimized solution, the lower surface of the punch template is provided with upper mounting grooves corresponding to the cylindrical punch core and the annular punch core, respectively.

[0019] As an optimized solution, the upper surface of the die template is provided with lower mounting grooves corresponding to the cylindrical die core and the annular die core, respectively.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] After the mold is installed, the material strip enters the mold from right to left during normal production. It first passes through the first set of cylindrical dies, which can complete the stamping of 5 products. After that, the material strip moves to the left and is formed by the second set of annular dies, which also punches out the frame waste. The punched frame waste has completed the forming of the cylindrical product. Therefore, a single mold can simultaneously form both annular and cylindrical products, effectively reducing waste.

[0022] It can effectively solve the problem of unusable waste material at the frame opening of ring-shaped products, improve material utilization, and integrate two molding systems into one mold, effectively saving investment in mold development and reducing operation and maintenance costs such as mold debugging and maintenance, saving manpower and time costs; moreover, by producing two products with one mold, production efficiency is greatly improved, and the output value of mold production is also increased, improving material utilization while reducing material waste and maximizing the application of material value.

[0027] like Figure 1As shown, the composite mold integrating the forming functions of ring and cylindrical products includes a punch template 4 and a die template 9 arranged side by side from top to bottom, and a material strip 13 feeding area is formed through the area between the punch template 4 and the die template 9. The punch template 4 is set to rise and fall vertically. The die template 9 is provided with a cylindrical die core 8 and an annular die core 7 in sequence along the feeding direction of the material strip 13. The punch template 4 is provided with a cylindrical punch core 6 and an annular punch core 5 that match the cylindrical die core 8 and the annular die core 7.

[0028] The punch template 4 is fixed on the punch base 1.

[0029] A punch pad 3 is fixedly connected between the upper surface of the punch template 4 and the lower surface of the punch base 1.

[0030] The die template 9 is fixed on the die base 12.

[0031] A die pad 10 is fixedly connected between the lower surface of the die template 9 and the upper surface of the die base 12.

[0032] A guide sleeve 2 is vertically fixed to the lower surface of the punch mold base 1, and a guide post 11 inserted into the guide sleeve 2 is vertically fixed to the upper surface of the die mold base 12.

[0033] There are four guide sleeves 2 and four guide posts 11, which are located near the four corners of the punch mold base 1 and the die mold base 12.

[0034] The lower surface of the punch template 4 is provided with upper mounting grooves corresponding to the cylindrical punch core 6 and the annular punch core 5.

[0035] The upper surface of the die template 9 is provided with lower mounting grooves corresponding to the cylindrical die core 8 and the annular die core 7.

[0036] The punch base 1 and the die base 12 mainly fix the punch and die pads 3 and the punch and die templates 4.

[0037] The guide sleeve 2 and guide post 11 mainly serve to guide and position the mold during the opening and closing process of stamping.

[0038] The punch backing plate 3 and the punch template 4 mainly serve to fix the punch core;

[0039] The annular punch 5 and annular die 7 mainly form the annular product 15;

[0040] The cylindrical punch 6 and cylindrical die 8 mainly form cylindrical products 14;

[0041] The die template 9 and the die backing plate 10 mainly serve to fix the die core;

[0042] The product ejection methods involved in the stamping dies are all well-known in the field, such as the use of ejector pins. The specific assembly methods of the mold core, template, backing plate and mold base are also common knowledge in the field of stamping dies. Since they are not innovative in this solution, they will not be elaborated on here.

[0043] The working principle of this device is as follows:

[0044] After the mold is installed, during normal production, the strip 13 enters the mold from right to left. It first passes through the first set of cylindrical punches and dies, which can complete the stamping of 5 products. After completion, the strip 13 moves to the left, where the second set of annular punches and dies completes the forming of the annular product 15 and punches the frame waste. The punched frame waste has completed the forming of the cylindrical product 14. Therefore, a single mold can simultaneously form both the annular product 15 and the cylindrical product 14, effectively reducing waste.

[0045] It can effectively solve the problem of waste material utilization at the 15-frame opening of ring products, improve material utilization rate, and at the same time improve production efficiency and reduce investment in mold development and subsequent mold maintenance costs.
