Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a die frame for installing a hardware stamping die. Background Art

[0002] A stamping die is a special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. It is called a cold stamping die (commonly known as a cold stamping die). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation, thereby obtaining the desired parts.

[0003] A Chinese patent discloses a common die frame for metal stamping dies (authorization announcement number CN217095337U). This patented technology evenly installs multiple spring telescopic columns on the top of the die platform. By utilizing the elasticity of the spring telescopic columns, when the stamping bottom die is placed on top of the die, the gravity of the stamping bottom die can press down a depression that matches it. Then, the position of the U-shaped clamps on both sides is adjusted by the adjustment mechanism, so that the U-shaped clamps on both sides can clamp the two sides of the stamping bottom die. Therefore, when the die needs to be replaced, only the die needs to be replaced, avoiding the tediousness of synchronously replacing the die frame.

[0004] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: after stamping, the existing stamping die frame will cause the stamped material to be tightly combined with the lower die, making it inconvenient for the user to remove the stamped material, thus affecting the overall work efficiency. Utility Model Content

[0005] The technical problem to be solved by the utility model is that after the stamping die in the prior art completes the stamping, the stamped part is tightly fitted with the lower die and is not convenient to be taken out, which affects the work efficiency. For this reason, we propose a die frame for installing the metal stamping die.

[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: a mold frame for installing a hardware stamping mold, comprising a lower mold and an upper mold, the upper mold is arranged on the top of the lower mold, a mounting block is installed inside the lower mold, an ejection block is arranged on the top of the mounting block, a sleeve is fixedly connected to the bottom of the ejection block on all sides, a support column is slidably connected to the inside of the sleeve, a return spring is sleeved on the surface of the support column, the top of the return spring is fixedly connected to the bottom of the sleeve, and the bottom of the return spring is fixedly connected to the top of the mounting block.

[0007] Preferably, both sides of the mounting block are fixedly connected to a shell, slots are provided at the tops of both sides of the inner cavity of the lower mold, an insertion rod is slidably connected inside the slot, the bottom of the insertion rod passes through the top of the shell and is fixedly connected to the first movable block, the front and rear ends of the shell are provided with through holes, a control rod is slidably connected inside the through hole, an end of the control rod close to the first movable block is fixedly connected to the second movable block, and an end of the control rod away from the second movable block is fixedly connected to the control block.

[0023] Reference Figure 3-Figure 5As shown, in this embodiment: both sides of the mounting block 3 are fixedly connected with the shell 8, the tops of both sides of the inner cavity of the lower mold 1 are provided with slots 9, the inside of the slots 9 is slidably connected with the insertion rod 10, the bottom of the insertion rod 10 passes through the top of the shell 8 and is fixedly connected with the first movable block 11, the front and rear ends of the shell 8 are provided with through holes 12, the inside of the through hole 12 is slidably connected with the control rod 13, the end of the control rod 13 close to the first movable block 11 is fixedly connected with the second movable block 23, and the end of the control rod 13 away from the second movable block 23 is fixedly connected with the control block 14, by pressing the control block 14, the control rod 13 drives the second movable block 23 to move, and the first movable block 11 is squeezed by the second movable block 23 to move downward, thereby driving the insertion rod 10 to disengage from the inside of the slot 9 to release the limit on the mounting block 3, so as to facilitate the user to take out the mounting block 3, and then replace the appropriate ejection block 4 according to the size of the stamping part.

[0024] Reference Figure 5 As shown, in this embodiment: the bottom of the first movable block 11 is fixedly connected with the first spring 15, and the bottom of the first spring 15 is fixedly connected to the bottom end of the shell 8. By pressing the control block 14, the second movable block 23 squeezes the first movable block 11, so that the insertion rod 10 enters the shell 8. When the mounting block 3 is placed in the lower mold 1, the control block 14 is released, and the upward thrust generated by the first spring 15 causes the insertion rod 10 to be inserted into the slot 9, thereby fixing the position of the mounting block 3 to prevent the ejection block 4 from being offset during use.

[0025] Reference Figure 5 As shown, in this embodiment: a second spring 16 is sleeved on the surface of the control rod 13, and one end of the second spring 16 close to the control block 14 is fixedly connected to the control block 14, and one end of the second spring 16 away from the control block 14 is fixedly connected to the housing 8.

When the stamping part is stamped by the upper die 2, the ejector block 4 moves downward through the sleeve 5, and the reset spring 7 is charged. When the stamping is completed and the upper die 2 moves upward, the elastic force released by the reset spring 7 causes the ejector block 4 to move upward, so that the stamping part is ejected from the inside of the lower die 1, so that the staff can take out the stamping part. By pressing the control block 14, the control rod 13 drives the second movable block 23 to move. The second movable block 23 squeezes the first movable block 11 to move the first movable block 11 downward, thereby driving the insertion rod 10 to disengage from the inside of the slot 9, so as to release the limit of the installation block 3, so that the user can take out the installation block 3, and then according to the punching The size of the pressing piece is replaced with an appropriate ejector block 4, and the second movable block 23 is pressed against the first movable block 11 by pressing the control block 14, so that the insertion rod 10 enters the interior of the shell 8. When the mounting block 3 is placed inside the lower mold 1, the control block 14 is released, and the upward thrust generated by the first spring 15 is used to insert the insertion rod 10 into the interior of the slot 9, thereby fixing the position of the mounting block 3 to prevent the ejector block 4 from shifting during use. After the control block 14 is released, the thrust of the second spring 16 on the control block 14 causes the control block 14 to drive the second movable block 23 away from the first movable block 11 through the control rod 13, and the position of the second movable block 23 is limited to prevent the second movable block 23 from squeezing the first movable block 11.
