Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a mold structure that is easy to disassemble. Background Technology

[0002] Stamping is a pressure processing method that uses a die mounted on a press to apply pressure to a material at room temperature, causing it to separate or plastically deform, thereby obtaining the desired part; stamping dies are used when processing parts.

[0003] Punching dies are a type of stamping die. Small punching dies are generally installed on small punch presses. The installation process requires the use of multiple bolts for fixing. For example, the upper and lower dies of a small punching die need to be fixed to the punch and worktable of the small punch press with multiple bolts respectively. This makes the disassembly process of the punching die quite cumbersome. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 In this embodiment of the invention, a mold structure that is easy to disassemble includes a punch press 2 and a punching die 1. Both the punch press 2 and the punching die 1 are existing technologies, and their specific structures and working principles will not be described in detail here. Figure 1 A pneumatic punch press 2 is selected, while the punching die 1 is a common die for punching strip holes in sheet metal. The punch head 202 of the punch press 2 is fixedly mounted with a connector head 4. The bottom of the connector head 4 has multiple T-slots 5. The upper die 101 of the punching die 1 is fixed with multiple connecting posts 102 with T-shaped cross-sections, and the upper die 101 is slidably inserted into the T-slots 5 through the connecting posts 102. The lower die 103 of the punching die 1 is fixed on the punch table 201 of the punch press 2. The bottom of the punch table 201 of the punch press 2 is provided with a fixing mechanism 3. The fixing mechanism 3 includes a base frame 301 fixed to the bottom of the punching table 201 and two sliding rods 309 slidably inserted into the punching table 201. A pressure block 310 is fixed to the top of the sliding rod 309. Both ends of the lower die 103 of the punching die 1 are provided with straight grooves 104 with a width consistent with the diameter of the sliding rods 309. The top of the lower die 103 of the punching die 1 is provided with a hole groove 105. One end of the straight groove 104 overlaps with the hole groove 105. The base frame 301 is provided with a pressing mechanism that allows the two sliding rods 309 to move down synchronously.

[0023] As can be seen from the above connection relationship: During installation, the punching die 1 is placed on the punch table 201 of the punch press 2. At this time, the connecting post 102 of the upper die 101 of the punching die 1 is aligned one-to-one with the T-slot 5 on the punch head 202 of the punch press 2. At this time, the straight groove 104 of the lower die 103 of the punching die 1 is aligned with the two sliding rods 309. Then, the entire punching die 1 is pushed, and the upper die 101 slides into the T-slot 5 through the connecting post 102, while the sliding rods 309 enter the straight groove 104. The pressure block 310 on the slide rod 309 is aligned with the hole groove 105 until it contacts the inner wall of one end of the straight groove 104. At this time, the pressing mechanism causes the two slide rods 309 to move down synchronously until the pressure block 310 of the slide rod 309 contacts the inner wall of the bottom of the hole groove 105, thereby fixing the punching die 1. It can be seen that the punching die 1 can be installed without the aid of bolts. At the same time, the installation and disassembly process is simple and not complicated, which greatly improves the efficiency of die replacement and facilitates the disassembly and maintenance of maintenance workers in the later stage.

[0024] Specifically, the pressing mechanism includes two moving blocks 304. A guide structure is shared at the bottom of both moving blocks 304. Side plates 307 are fixed to both sides of each moving block 304, and inclined grooves 308 are formed on opposite sides of each side plate 307. A crossbar 311 is slidably mounted on the two inclined grooves 308 on each moving block 304. The two crossbars 311 are respectively fixed to two sliding rods 309. A centering mechanism for the centering movement of the two moving blocks 304 is provided inside the base frame 301. (See attached...) Figure 2 and appendix Figure 4 As shown, when the two moving blocks 304 move away from each other, the crossbar 311 moves down along the inclined groove 308, thereby causing the crossbar 311 to drive the slide bar 309 to move down.

[0025] Specifically, the guide structure includes a guide rail 306 and two sliders 305 that are slidably sleeved on the guide rail 306. The two sliders 305 are respectively fixed to two moving blocks 304. The guide structure is designed to improve the stability of the moving blocks 304 and provide support for the bottom of the moving blocks 304.

[0026] Specifically, the centering mechanism includes a double-threaded rod 303 with opposite thread directions at both ends. Threaded holes are provided on the outer sides of two moving blocks 304, and the thread directions of the two moving blocks 304 are opposite. The two moving blocks 304 are respectively installed on both ends of the double-threaded rod 303 through the threaded holes. Bearing seats 302 are fixed at both ends of the base frame 301. The two ends of the double-threaded rod 303 are rotatably installed on the two bearing seats 302. When the double-threaded rod 303 rotates, it drives the moving blocks 304 to move through the threaded transmission.

[0027] Specifically, both ends of the double threaded rod 303 are fixed with Z-shaped handles. The Z-shaped handles are designed to make it easier for workers to rotate the double threaded rod 303.

[0028] Specifically, the outside of the Z-shaped handle is wrapped with a rubber layer to increase friction.

[0029] Specifically, the edges of the slot 105 are all chamfered to facilitate the entry of the pressure block 310 into the slot 105.

[0030] Working principle:

[0031] During installation, the punching die 1 is placed on the punch table 201 of the punch press 2. At this time, the connecting post 102 of the upper die 101 of the punching die 1 is aligned one-to-one with the T-slot 5 on the punch head 202 of the punch press 2. At this time, the straight groove 104 of the lower die 103 of the punching die 1 is aligned with the two sliding rods 309. Then, the entire punching die 1 is pushed, and the upper die 101 is slidably inserted into the T-slot 5 through the connecting post 102. At the same time, the sliding rods 309 enter the straight groove 104 until they contact the inner wall of one end of the straight groove 104.

[0032] The worker rotates the double threaded rod 303 using a Z-shaped handle. The double threaded rod 303 drives the moving block 304 to move through the threaded transmission. When the two moving blocks 304 move away from each other, the crossbar 311 moves down along the inclined groove 308, thereby driving the sliding rod 309 down until the pressure block 310 of the sliding rod 309 contacts the inner wall of the bottom of the slot 105, thus fixing the punching die 1. It can be seen that the punching die 1 can be installed without the aid of bolts. At the same time, the installation and disassembly process is simple and not cumbersome, which greatly improves the efficiency of die replacement and facilitates the disassembly and maintenance of workers in the later stage.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
