Description

Technical Field

[0001] This utility model mainly relates to the technical field of stamping dies, specifically a stamping die that facilitates the replacement of plastic plates. Background Technology

[0002] Stamping dies are used to shape sheet metal or other plastic materials into desired shapes and sizes through pressure. This process includes various techniques such as blanking, bending, stretching, and bulging, all of which rely on the specific shape and structure of the die. Using stamping dies can significantly improve production efficiency. Once the die is designed and manufactured, mass production can begin, and the shape and size of each product can remain consistent. However, existing stamping dies typically require demolding when changing plastic sheets, necessitating lifting equipment and wasting manpower and resources. Therefore, a stamping die that facilitates the replacement of plastic sheets is needed.

[0003] According to application number 202323359466.4, a stamping die that is easy to change molds includes a housing assembly and a positioning support assembly. An auxiliary upper ejector mechanism is installed at the lower center line of the housing assembly. The auxiliary upper ejector mechanism includes a connecting frame, a pressure rod, a first piston, an air storage cylinder, a lower guide pipe, an upper ejector cylinder, a second piston, a first spring, and an upper ejector rod. The pressure rod is connected to the lower rear side of the connecting frame. The air storage cylinder is connected to the outside of the first piston. The upper ejector cylinder is connected to the end of the lower guide pipe away from the air storage cylinder. The first spring is connected to the upper end of the second piston, and the upper ejector rod is connected to the upper end of the first spring. The positioning support assembly is located on the left and right sides of the lower end of the housing assembly.

[0004] The aforementioned document describes how adding a quick-assembly and disassembly structure makes it easier to change the corresponding mold according to the equipment requirements. However, the disassembly and assembly process still requires mold removal and the coordinated operation of various components, resulting in a high failure rate and limited savings in manpower and resources.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Example

[0026] Please refer to the attached document carefully. Figure 1 , 2As shown in Figures 3, 4, and 5, a stamping die for easy replacement of plastic sheets includes a lower die 10, an upper die 11 at the top of the lower die 10, a first slot 12 in the upper part of the lower die 10, a lower plastic sheet 13 that can be pulled out inside the first slot 12, a lifting component 14 at the bottom of the first slot 12 to support the lower plastic sheet 13, and support components 15 at both ends of the lifting component 14 that are opened inside the lower die 10. A second slot 16 in the lower part of the upper die 11, an upper plastic sheet 17 that can be pulled out inside, and edge members 18 at both ends of the upper die 11 on the outlet side of the second slot 16. Supporting steel bars 131 are welded to the upper ends of the lower plastic sheet 13. A steel bar slide 132 is opened in the upper half of the first slot 12. A sealing plate 133 is provided on the top outlet side of the steel bar slide 132. A first hinged handle 134 is provided on the outlet side of the lower plastic sheet 13. The lifting component 14 includes a rectangular... The rectangular slide 141 has a double-threaded rod 142 rotatably connected to both ends inside. Two sliding columns 143 are connected to the side wall of the double-threaded rod 142 by a nut. The bottom of the lower plastic plate 13 is provided with a support plate 144 that slides on the lower half of the first draw groove 12. The sliding column 143 is hinged to one end of the support plate 144 by a double-headed hinge rod 145. The lower mold 10 has a knob 146 at one end outside. The knob 146 is fixedly connected to the central shaft of one end of the double-threaded rod 142. Two sliders 1441 are welded to both ends of the support plate 144. The lower half of the first draw groove 12 has a first slide 1442 for the sliders 1441 to slide at both ends. The support component 15 includes a second slide 151 opened at both ends of one side of the lower mold 10. The second slide 151 passes through the lower half of the first slide 1442. A support steel plate 152 is slidably provided inside the second slide 151. A ring handle 153 is provided on the outlet side of the support steel plate 152.

[0027] As described above, during mold closing, the sealing plate 133 on the top outlet side of the steel strip slide 132 forms a limiting ring with the lower mold 10, restricting the top of the lower plastic plate 13 and preventing it from shaking. Since the support plate 144 is easily offset or damaged when supported solely by the sliding column 143 and double-headed hinge rod 145 connected by a nut during mold closing, a support component 15 is added to this device for stable support. When the support steel plate 152 is completely embedded in the second slide 151, it can block the lower half of the first slide 1442 and support the two sliders 1441 at both ends of the support plate 144, thereby providing stable support for the lower plastic plate 13. Therefore, when it is necessary to remove the lower plastic plate 13 during mold closing... When lowering the plastic plate 13, first use the ring handle 153 to pull the support steel plate 152 out of the second slide groove 151 a certain distance, releasing the lower half of the first slide groove 1442. Then, rotate the double-threaded rod 142 by rotating the knob 146, so that the two sliding columns 143 move closer to each other, the double-headed hinge rod 145 opens and tilts, and the support plate 144 descends, so that the lower plastic plate 13 is demolded and lowered. When the support steel bar 131 on the lower plastic plate 13 falls into the bottom end of the steel bar slide groove 132 in the upper half of the first draw groove 12, the lower plastic plate 13 can be pulled out from the first draw groove 12 by the first hinge handle 134 for adjustment or replacement. When the lower plastic plate 13 needs to be installed, the above steps are reversed.

[0028] Please refer to the attached document carefully. Figure 1 , 2 As shown in Figure 6, wide steel plates 171 are welded to both ends of the upper plastic plate 17. The upper half of the second draw groove 16 is provided with a steel plate groove 172 to facilitate the sliding of the wide steel plate 171. A second hinged handle 173 is provided on the outlet side of the upper plastic plate 17. The side guard component 18 includes two third grooves 181 opened at both ends on one side of the upper mold 11. The opening of the third groove 181 is close to the opening of the second draw groove 16. A baffle 182 is slidably provided inside the third groove 181. A push button 183 is welded to the middle of the baffle 182 on the outer side of the upper mold 11. A spring 184 is provided at one end of the baffle 182 that is embedded in the second draw groove 16 and connected to the inner wall of the second draw groove 16.

[0029] As described above, the wide steel plate 171, which is inserted into the steel plate groove 172, can support the upper plastic plate 17 and prevent it from falling off. The edge member 18 blocks the outlet side of the upper plastic plate 17 to prevent it from shaking. In this embodiment, various protruding guide pillars are concentrated on the lower plastic plate 13. The bottom end of the upper plastic plate 17 is a plastic plate with an integrated groove. If the structure of the lower plastic plate 13 is opposite to that of the upper plastic plate 17, the overall structure should also be reversed. When it is necessary to remove the upper plastic plate 17 during mold closing, the lower plastic plate 13 is first lowered to the bottom to complete the demolding between the lower plastic plate 13 and the upper plastic plate 17. Then, the push button 183 is pressed to drive the baffle 182 to slide inside the second groove 16. The spring 184 retracts. After the baffle 182 is completely inserted into the second groove 16, the upper plastic plate 17 can be removed from the second groove 16 through the second hinge handle 173.

[0030] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
