Description

Technical Field

[0001] This utility model relates to the field of stamping forming equipment technology, and in particular to a head stamping forming equipment. Background Technology

[0002] An end cap is a component used to seal the end of a container and isolate it from the internal and external media. It is also called an end cap. According to the shape of the end cap surface, it can be divided into convex, conical, flat and combined types.

[0003] In the production process of common convex heads, a stamping device is required to perform cold stamping forming. Traditional stamping devices can meet the basic production needs. However, in actual applications, after the head is stamped, it is easy to get stuck in the mold cavity, and manual tools are still needed to solve the problem. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a head stamping forming device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A head stamping forming device includes a stamping table. A lower die is mounted on the middle of the stamping table via a mounting platform. A push block is mounted on the middle of the lower die via a limiting groove. The bottom of the push block is connected to the telescopic end of a cylinder via a connecting rod. Mounting grooves are provided at the two corners of the upper end of the push block. A flip plate is rotatably mounted in the mounting groove. A rubber sealing gasket is provided on the inner wall of the flip plate. When the flip plate is closed, the rubber sealing gasket covers the air nozzle provided on the inner wall of the mounting groove to seal the air nozzle.

[0007] Furthermore, in a preferred configuration, an upper mold is disposed directly above the lower mold, and the upper mold is connected to a hydraulic telescopic cylinder to achieve the stamping action.

[0008] In addition, a preferred structure is that a cylinder is installed inside the mounting platform, and the telescopic end of the cylinder is connected to the bottom of the push block through a connecting rod. The connecting rod is limited and assembled in the mounting cylinder provided at the upper end of the mounting platform.

[0009] In addition, a preferred structure is that an air pump is installed on one side of the interior of the mounting platform, and the air outlet of the air pump is connected to a pair of connecting pipes, the other end of each connecting pipe extending into the push block and connected to the air nozzle.

[0010] In addition, a preferred structure is that a flip plate is rotatably mounted on the bottom side of the inner wall of the mounting groove, an elastic strip is fixedly connected to the inner side of the flip plate, and the other side of the elastic strip is fixedly connected to the inner wall of the mounting groove.

[0011] Furthermore, a preferred structure is that the elastic strip is V-shaped, and the elastic strip bends and deforms when the flip plate is closed.

[0012] The beneficial effects of this utility model are as follows:

[0013] In this invention, a push block controlled by a cylinder is provided in the mold cavity of the lower mold part. During the ejection process, the push block pushes and contacts the bottom wall of the workpiece. During this process, the flip plate automatically opens and sprays gas to fill the gap between the workpiece and the mold cavity, so as to achieve the effect of rapid demolding, avoid the situation where the workpiece is stuck and difficult to remove, and effectively improve work efficiency.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-3 A head stamping forming device includes a stamping table 1. A lower mold 4 is provided in the middle of the stamping table 1 via a mounting table 2. A push block 5 is mounted in the middle of the lower mold 4 via a limiting groove 41. The bottom of the push block 5 is connected to the telescopic end of a cylinder 12 via a connecting rod 51. Mounting grooves 13 are provided at the two corners of the upper end of the push block 5. A flip plate 10 is rotatably mounted in the mounting groove 13. A rubber sealing gasket 9 is provided on the inner side wall of the flip plate 10. When the flip plate 10 is closed, the rubber sealing gasket 9 covers the air nozzle 8 provided on the inner wall of the mounting groove 13 to seal the air nozzle 8.

[0020] An upper die 3 is positioned directly above the lower die 4, and the upper die 3 is connected to a hydraulic telescopic cylinder to achieve the stamping action.

[0021] The mounting platform 2 is equipped with a cylinder 12. The telescopic end of the cylinder 12 is connected to the bottom of the push block 5 through a connecting rod 51. The connecting rod 51 is limited and fitted inside the mounting cylinder 6 set at the upper end of the mounting platform 2.

[0022] An air pump 7 is installed on one side of the interior of the mounting platform 2. The air outlet of the air pump 7 is connected to a pair of connecting pipes 71. The other end of each connecting pipe 71 extends into the push block 5 and is connected to the air nozzle 8.

[0023] A flip plate 10 is rotatably mounted on the bottom side of the inner wall of the mounting groove 13. An elastic strip 11 is fixedly connected to the inner side of the flip plate 10, and the other side of the elastic strip 11 is fixedly connected to the inner wall of the mounting groove 13.

[0024] The elastic strip 11 is V-shaped, and when the flip plate 10 is closed, the elastic strip 11 bends and deforms, and the elastic strip 11 deforms to generate a rebound force.

[0025] In this embodiment, after the stamping is completed, the upper die 3 moves upward. At this time, the cylinder 12 drives the push block 5 to push upward and push the bottom wall of the workpiece in the mold cavity. When the upper flip plate 10 of the push block 5 is disengaged from the limiting groove 41, under the rebound action of the elastic strip 11, the flip plate 10 quickly flips outward through the elastic strip 11. At this time, the rubber sealing gasket 9 no longer contacts the air nozzle 8 in the mounting groove 13. The air nozzle 8 sprays out gas and quickly fills the gap between the mold cavity and the workpiece to achieve the purpose of rapid demolding and stable demolding.

[0026] By rapidly filling the gap between the mold cavity and the workpiece with gas, the workpiece can be separated from the inner wall of the mold cavity more quickly, and the process is more efficient and stable than direct ejection demolding.

[0027] In its natural state, push block 5 fits into the mold cavity to ensure the integrity of the mold cavity.

[0028] The elastic strip 11 is a steel strip with a certain degree of elasticity. When the elastic strip 11 rotates on the flip plate 10, it performs corresponding compression and spring-out operations.

[0029] During the retraction stroke of the push block 5 driven by the cylinder 12, the push block 5 is forced to reset by the pressure of the inner wall of the mold cavity. At this time, the push block rotates in the mounting groove 13 and squeezes the elastic strip 11, and the rubber sealing gasket 9 is re-covered on the air nozzle 8 to ensure airtightness.

[0030] The air pump 7 pumps gas to the nozzle 8 through the connecting pipe 71.

[0031] Push block 5 is shaped like a cross.

[0032] The upper mold 3 is driven by a hydraulic telescopic rod to stamp the workpiece in the cavity of the lower mold 4. The specific stamping principle and process are existing technologies and will not be explained further.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
