Description

Technical Field

[0001] The utility model relates to the technical field of stamping devices, in particular to a stamping device. Background Art

[0002] Printers are an important office equipment, and their market demand is growing. In the manufacturing process of printers, ink tank caps are key components, and their quality and production efficiency directly affect the overall performance and market competitiveness of printers. The printer ink tank cap model processing and stamping device is an efficient, accurate and reliable processing equipment, which is of great significance to improving the competitiveness of the printer manufacturing industry. In the stamping operation, the raw materials are placed between the upper and lower molds, and the upper mold is driven downward by the cylinder to stamp the raw materials in the lower mold. After the stamping operation is completed, the molded product is taken out from the lower mold. In order to improve demoulding efficiency, some stamping devices are provided with an ejection structure inside the lower mold to eject the molded model, thereby achieving the purpose of demoulding;

[0003] The traditional stamping device still has some shortcomings when in use: the use of an additional ejection structure for discharging operations increases the steps and time in the production process. After each stamping operation, the ejection structure needs to be started separately to eject the product, which affects the production efficiency. In addition, the additional ejection structure requires an additional power source and control system to drive, which not only increases energy consumption, but also leads to an increase in the volume of the overall equipment and occupies more production space. Therefore, a stamping device is proposed to address the above situation. Utility Model Content

After each stamping operation, the ejection structure needs to be started separately to eject the product, which affects the production efficiency. In addition, the additional ejection structure requires an additional power source and control system to drive, which increases the energy consumption. A stamping device is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A punching device comprises a support frame on which a cylinder is arranged.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-4 A stamping device comprises a base 1, a support frame 2, a lower mold 4, an upper mold 5 and an ejection assembly 6. The upper mold 5 is provided with two pairs of hollow holes. The top of the lower mold 4 is provided with two pairs of guide columns, and the two pairs of guide columns cooperate with the two pairs of hollow holes. The support frame 2 and the lower mold 4 are respectively arranged on the top of the base 1. The top of the base 1 is provided with two rows of threaded holes. The lower mold 4 is provided with two rows of bolts, and the two rows of bolts cooperate with the two rows of threaded holes. The cross-sectional projection of the support frame 2 is in an inverted "L" shape. The top of the lower mold 4 is provided with a mold cavity 401, and rectangular grooves 402 are respectively provided on both sides of the mold cavity 401. The support frame 2 is provided with a cylinder 3. The top of the upper mold 5 is connected to the moving end of the cylinder 3. The support frame 2 A through hole is formed through the top, and the movable end of the cylinder 3 cooperates with the through hole. A pair of movable grooves 501 are formed on the top of the upper mold 5, and grooves 502 are formed at both ends of the bottom of the upper mold 5. The ejection assembly 6 includes a T-shaped rod 601 that is clearance-fitted on the pair of movable grooves 501, a template 602 connected to the two T-shaped rods 601, and a limit block 603 arranged on the template 602. The size and shape of the template 602 are adapted to the mold cavity 401, and the size of the T-shaped rod 601 is adapted to the rectangular groove 402. Further, the size here refers to the length and width, and the size of the limit block 603 is adapted to the groove 502. Further, the size here refers to the length, width and height.

[0025] The use method and advantages of the utility model: When the punching device is in use, the working process is as follows:

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when using the device, firstly, the electrical equipment in the device is connected to an external power supply and switch, and the switch of the cylinder 3 is turned on to make it work. The operation of the cylinder 3 causes the upper mold 5 to descend, so that the T-shaped rod 601 follows the decline. When the T-shaped rod 601 descends to the limit block 603 and contacts the top surface of the lower mold 4, the cylinder 3 is turned off. At this time, the template 602 contacts the bottom surface of 101. At this time, the device as a whole is in the initial working state. Then the raw material is placed in 101, that is, the raw material contacts the template 602, and the switch of the cylinder 3 is turned on to make it work. The cylinder 3 works to push the upper mold 5 down. The movable groove 501 and the T-shaped rod 601 are matched with each other in clearance, so the upper mold 5 can be lowered to realize the stamping operation. At this time, the limit block 603 is matched in the groove 502 to ensure that the upper mold 5 and the lower mold 4 are closely fitted to complete the stamping work. After the stamping is completed, the switch of the cylinder 3 is turned on again to make it work. The cylinder 3 drives the upper mold 5 to rise. When the upper mold 5 rises to contact the top of the T-shaped rod 601, due to the shape of the ejection component 6, the continuous rise of the upper mold 5 will drive the T-shaped rod 601 to rise, and then the template 602 will rise, so that the template 602 can lift the formed product out.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
