Description

Technical Field

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

[0002] An iron box is a container for packaging bullets, usually made of cold-rolled low-carbon steel sheet 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 packaging iron box pull ring for closing and fixing, which is similar to the principle of the pull ring of a beverage can, to ensure that the bullets will not be damaged due to external factors.

[0003] When the existing packaging iron box pull rings are produced and processed, multiple sets of single-process dies need to be used for production in sequence to obtain the products. Specifically, a feeder is used to feed the strip of the raw material for the packaging iron box pull rings into each process die, and then the slider of the existing press drives each group of single-process dies installed on the tabletop of the fixed table to stamp the strip to obtain the finished product of the packaging iron box pull ring. The production efficiency is low and the labor cost is high. Therefore, in view of this, the inventor provides a continuous die for the packaging iron box pull ring 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 the traditional packaging iron box pull rings are produced, multiple sets of single-process dies need to be used for stamping in sequence to obtain the finished product, 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 the pull ring of a packaging iron box, including an upper die base detachably connected to the slider of a press and a lower die base detachably connected to the tabletop 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. A lower template is provided on one side of the lower die base close to the upper die base, a lower backing plate is provided between the lower die base and the lower template, and 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 assembly for separating the finished product obtained by stamping from the lower template is provided between the bottom of the upper clamping plate and 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 the packaging iron box pull ring, which simplifies the production operation and production scale of the packaging iron box pull ring, thereby reducing the production cost. At the same time, a feeder is used to push the material strip of the production material of the packaging iron box pull ring between the upper mold base and the lower mold base, thereby facilitating the continuous production of the packaging iron box pull ring, greatly improving the production efficiency, and solving the problem that the traditional production of the packaging iron box pull ring requires the use of multiple sets of single-process molds for stamping processing in sequence to obtain the finished product, which has complicated steps, reduces the production efficiency, and increases the production cost.

[0008] 2. Compared with the prior art, the utility model sets 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 in each step in the continuous shaping cavity until the material strip is stamped by the upper clamping plate and the lower template to have the same external structure as the last step in the continuous shaping cavity, so that the production process of the packaging iron box pull ring is more coherent, and by setting a stripping component, it is convenient to demold and unload the packaging iron box pull ring product obtained after the stamping process.

[0009] 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. One end of the lower template is also provided with a feeding trough for unloading the finished product of the packaging iron box pull ring from the lower template. A structural connector is provided between the upper pad, the upper clamping plate, the stop plate and the stripping plate. By providing the stop plate and the stripping plate, it is convenient to guide the strip after stamping, and by providing the feeding trough, it is convenient to receive and accommodate the finished product of the packaging iron box pull ring removed by the stripping mechanism, so that the output and unloading operation of the finished product of the packaging iron box pull ring is more convenient.

[0010] Furthermore, the structural connection member includes a first locating pin installed and connected between the upper pad and the upper clamping plate and a second locating pin installed and connected between the stop plate and the stripping plate, and the stop plate and the upper clamping plate are fixedly connected. By providing the first locating pin and the second locating pin, it is convenient to install and connect the overall structure of the upper die base, which is not only convenient for assembly and disassembly, but also improves the stability of the connection between the structures.

[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 packaging iron box pull ring. By setting the feeding trough, it is convenient to accommodate the finished product of the packaging iron box pull ring after it is removed from the lower template, and through the feeding port, it is convenient for the finished product of the packaging iron box pull ring to be completely separated from the lower template and completed.

[0012] Further, the bottom surface of the blanking port is an inclined slope surface connected to the lower template, and the cross-sectional area of the blanking port gradually increases from the end close to the continuous shaping cavity to the end far from the continuous shaping cavity. By setting the bottom surface of the blanking port as an inclined slope surface, it is convenient for guiding the blanking of the finished product of the packaging iron box pull ring in the blanking port.

[0013] Further, a third positioning pin is detachably installed and connected between the lower template and the lower backing plate. By setting the third positioning pin, it is convenient for the installation and connection between the lower template and the lower backing plate. The structure is simple, the disassembly and assembly are convenient, the connection between the structures is more compact, and it is also convenient for fixing the strip in the continuous shaping cavity.

The upper die base 1 and the lower die base 2 are arranged opposite to each other. A top clamping plate 3 is provided at the bottom of the upper die base 1, and an upper backing plate 4 is further provided between the top clamping plate 3 and the upper die base 1. A lower template 5 is provided on one side of the lower die base 2 close to the upper die base 1, a lower backing plate 6 is provided between the lower die base 2 and the lower template 5, and a continuous shaping cavity 7 for accommodating a strip for multiple stamping and shaping is provided between the lower template 5 and the top clamping plate 3. A stripping assembly for separating the finished product obtained by stamping from the lower template 5 is provided between the bottom of the top clamping plate 3 and the lower template 5. Among them, the existing feeder is driven by an intermittent driving mechanism to advance the strip for the stamping process.

[0020] Among them, as Figure 1 shown, the stripping assembly includes a stop plate 8 provided at the bottom of the top clamping plate 3 for limiting the strip and a stripping plate 9 provided at the bottom of the stop plate 8 for guiding the strip after stamping to separate from the lower template 5. A blanking groove 10 for discharging the finished product of the packaging iron box pull ring 13 from the lower template 5 is further provided at the right end of the lower template 5. Structural connectors are provided between the upper backing plate 4, the top clamping plate 3, the stop plate 8 and the stripping plate 9.

[0021] Among them, as Figure 1 shown, the structural connectors include a first positioning pin 11 installed and connected between the upper backing plate 4 and the top clamping plate 3 and a second positioning pin 12 installed and connected between the stop plate 8 and the stripping plate 9.

The length of the blanking chute 14 is less than the length of the finished product of the packaging iron box pull ring 13.

[0023] Among them, as Figure 1 shown, the bottom surface of the blanking port 15 is an inclined slope surface connected to the lower template 5, and the cross-sectional area of the blanking port 15 gradually increases from the end close to the continuous shaping cavity 7 to the end far from the continuous shaping cavity 7.

[0024] Among them, as Figure 1 shown, a third positioning pin 16 is detachably installed and connected between the lower template 5 and the lower backing plate 6.

[0025] In the specific implementation process of the present utility model, the feeder drives the strip of raw materials for the production of the pull ring 13 of the packaging iron box into the continuous shaping cavity 7 and intermittently pushes it in the continuous shaping cavity 7. When the strip pauses in the continuous shaping cavity 7, the press drives its slider, upper die holder 1, upper clamping plate 3, etc. to press downward, thereby pressing the strip advanced and conveyed in the continuous shaping cavity 7. And so on. After the strip undergoes multiple stamping processes in the continuous shaping cavity 7, the finished product of the pull ring 13 of the packaging iron box is obtained. Subsequently, the finished product of the pull ring 13 of the packaging iron box is pushed to the right end of the continuous shaping cavity 7 and is in a suspended state at the right end of the continuous shaping cavity 7 and falls into the blanking chute 14 and slides out obliquely along the blanking port 15 to the outside of the lower template 5, thus completing the production of the pull ring 13 of the packaging iron box. Multiple processes are continuously processed and produced, and the coherence of the processes enables the production to be completed in one step.

[0026] Compared with the prior art, by setting the continuous shaping cavity 7 in the present utility model, it is convenient to perform continuous stamping processing on the strip. Only one set of continuous die is required to realize the multi-process production of the pull ring 13 of the packaging iron box, which simplifies the production operation and production scale of the pull ring 13 of the packaging iron box, thereby reducing the production cost. At the same time, the feeder is used to push the strip of raw materials for the production of the pull ring 13 of the packaging iron box between the upper die holder 1 and the lower die holder 2, which is convenient for the continuous production of the pull ring 13 of the packaging iron box, greatly improving the production efficiency, and solving the problem that in the production of the traditional pull ring 13 of the packaging iron box, multiple sets of single-process dies need to be used for stamping processing in sequence to obtain the finished product, with complicated steps, reduced production efficiency, and increased production cost.

[0027] Compared with the prior art, by setting the continuous shaping cavity 7 in the present utility model and using the press and the feeder to push and stamp the strip, the strip can be continuously stamped and shaped for each process in the continuous shaping cavity 7 until the strip is stamped by the upper clamping plate 3 and the lower template 5 to be the same as the outer shape structure of the last process in the continuous shaping cavity 7, making the production process of the pull ring 13 of the packaging iron box more coherent. By setting the stripping assembly, it is convenient to perform the demolding and blanking operation on the product of the pull ring 13 of the packaging iron box obtained after stamping processing.
