Description

Technical Field

[0001] This application relates to the technical field of molds, and specifically discloses a continuous die for iron box packing buckles. Background Art

[0002] An iron box is a container for packing bullets, usually made of cold-rolled low-carbon steel plate and coated with a layer of zinc on the surface to prevent rust. The closing method of the iron box usually requires the use of a special iron box packing buckle for closing and fixing, which is similar to the principle of the pull ring of a canned drink, to ensure that the bullets will not be damaged by external factors.

[0003] When the existing iron box packing buckles are produced and processed, multiple sets of single-process dies need to be used in sequence to obtain the products. Specifically, a feeder is used to feed the strip of the production raw material of the iron box packing buckle into each process die, and then each group of single-process dies installed on the table surface of the fixed table is driven by the slider of the existing press to stamp the strip to obtain the finished iron box packing buckle. The production efficiency is low and the labor cost is high. Therefore, in view of this, the inventor provides a continuous die for iron box packing buckles to solve the above problems. Summary of the Utility Model

[0004] The purpose of the present utility model is to solve the problem that when traditional iron box packing buckles are produced, multiple sets of single-process dies need to be used in sequence for stamping to obtain the finished products, the steps are complicated, the production efficiency is reduced, and the production cost is increased.

[0005] To achieve the above purpose, the basic scheme of the present utility model provides a continuous die for iron box packing buckles, which includes an upper die base detachably connected to the slider of a press and a lower die base detachably connected to the table surface of a fixed table. The upper die base and the lower die base are arranged opposite to each other. An upper clamping plate is provided at the bottom of the upper die base, and an upper backing plate is further provided between the upper clamping plate and the upper die base. An installation frame is provided at the bottom of the lower die base, and the installation frame is detachably connected to the table surface of the fixed table. A lower template is provided on one side of the lower die base close to the upper die base, and a lower backing plate is provided between the lower die base and the lower template. A continuous shaping cavity for accommodating the strip for multiple stamping and shaping is provided between the lower template and the upper clamping plate. A stripping component is provided between the bottom of the upper clamping plate and the lower template for separating the finished product obtained by stamping from the lower template.

[0006] The principle and effect of this basic scheme are as follows:

[0007] 1. Compared with the prior art, the utility model provides a continuous shaping cavity to facilitate continuous stamping processing of the material strip. Only one set of continuous molds is needed to realize multi-process production of iron box packing buckles, which simplifies the production operation and production scale of the iron box packing buckles, thereby reducing production costs. At the same time, a feeder is used to push the material strip of the production material of the iron box packing buckles between the upper mold base and the lower mold base, thereby facilitating the continuous production of the iron box packing buckles, greatly improving production efficiency, and solving the problem that in the traditional production of iron box packing buckles, multiple sets of single-process molds need to be used for stamping processing in sequence to obtain finished products, which has complicated steps, reduces production efficiency, and increases production costs.

[0008] 2. Compared with the prior art, the utility model sets up a continuous shaping cavity, and uses a press and a feeder to push and punch the material strip, so that the material strip can be continuously stamped and shaped step by step in the continuous shaping cavity, until the material strip is punched by the upper clamping plate and the lower template to the same shape structure as the last step in the continuous shaping cavity, making the production process of the iron box packing buckle more coherent.

[0009] 3. Compared with the prior art, the utility model provides a stripping assembly to facilitate the demoulding and unloading operation of the iron box packing buckle product obtained by the stamping process.

[0010] Furthermore, the stripping assembly includes a stop plate disposed at the bottom of the upper clamping plate and used to limit the material strip, and a stripping plate disposed at the bottom of the stop plate and used to guide the stamped material strip to separate from the lower template, and one end of the lower template is also provided with a feeding trough for unloading the finished iron box packing buckle from the lower template. By providing the stop plate and the stripping plate, it is convenient to guide the material strip after stamping, and by providing the feeding trough, it is convenient to receive and accommodate the finished iron box packing buckle removed by the stripping mechanism, making the output and unloading of the finished iron box packing buckle more convenient.

[0011] Furthermore, the feeding trough includes a feeding trough connected to the bottom of one end of the continuous shaping cavity and a feeding port connected to one end of the feeding trough, and the length of the feeding trough is less than the length of the finished product of the iron box packing buckle. By setting the feeding trough, it is convenient to accommodate the finished product of the iron box packing buckle after it is removed from the lower template, and through the feeding port, it is convenient for the finished product of the iron box packing buckle to be completely separated from the lower template and completed.

[0012] Furthermore, the bottom surface of the feed opening is an inclined slope surface connected to the lower template, and the cross-sectional area of ​​the feed opening gradually increases from the end close to the continuous shaping cavity to the end away from the continuous shaping cavity. By setting the bottom surface of the feed opening as an inclined slope surface, it is convenient to guide the finished product of the iron box packing buckle in the feed opening.

[0013] Further, the mounting bracket includes a lower supporting plate disposed below the lower die base and detachably connected to the tabletop of the fixed table, and a plurality of lower cushion pads disposed between the bottom of the lower die base and the lower supporting plate. By providing the lower supporting plate and the lower cushion pads, it is convenient to provide structural support for the lower die base, and at the same time, it is convenient for the installation and fixation of the lower die base on the fixed table, improving the stability of the overall structure.

[0014] Further, positioning pins are detachably connected and installed between the two ends of the lower cushion pad and the lower die base and the lower supporting plate respectively. By providing the positioning pins, it is convenient for the installation and connection of the lower cushion pad with the lower die base and the lower supporting plate. The structure is simple, the disassembly and assembly are convenient, and the connection between the structures is more compact. BRIEF DESCRIPTION OF THE DRAWINGS
