[0002] Stamping dies are special process equipment used to process materials into parts during cold stamping. They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform it, thereby obtaining the desired parts.

[0003] The prior art (publication number: CN 219025661 U) discloses a building stamping die, which specifically relates to the technical field of stamping dies, and comprises a base, wherein a die assembly for placing a workpiece is provided on the top of the base; a stamping assembly for stamping is provided on the top of the die assembly; a support assembly for supporting the stamping assembly is provided outside the stamping assembly; a ejector assembly for ejecting the workpiece is provided at the bottom of the die assembly; the ejector assembly comprises a movable plate, which is provided on the top of the base, and two ejector plates are fixedly provided on the top of the movable plate.

[0004] Although the above patent has a nested connection between the positioning column and the sleeve plate, so that the movable plate can move up and down with the punch head without affecting the stamping of the punch head, and as the punch head moves upward, the top plate will also push the workpiece in the template out, thereby improving the convenience of material unloading for the staff, but there are the following disadvantages. When in use, there is a lack of an effective safety baffle, and the staff's hands may mistakenly enter the stamping area and face the risk of being clamped or injured by the stamping mechanical parts, which may cause hand squeezing, cutting or other serious injuries. Further improvement is needed, and for this purpose, a construction stamping mold is proposed. Utility Model Content

[0005] The main purpose of the utility model is to provide a building stamping die, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A construction stamping die comprises a base, a lower die is installed at the front of the upper end of the base, a waste trough is opened in the middle of the upper end of the base, an L-shaped plate is installed at the rear of the upper end of the base, a hydraulic cylinder is installed at the upper end of the L-shaped plate, two guide plates symmetrically distributed on the left and right are installed on the upper wall of the L-shaped plate, a slidable hollow block is installed between the two guide plates, an upper die is installed at the lower end of the hollow block, a driving component is connected to the front end of the hollow block, a cross bar is installed at the front end of the two guide plates, a rotatable baffle is installed between the two cross bars, and a rubber pad is installed in the middle of the lower end of the baffle.

[0008] Preferably, a guide groove is provided at the upper end of the baffle, the guide groove is located above the upper mold, and the guide groove is located above the waste trough.

[0009] Preferably, the driving component comprises a rack, the rack is fixedly connected to the front right part of the hollow block, the rack is meshedly connected with a gear, and a connecting shaft is installed at the left end of the gear.

[0010] Preferably, the left end of the connecting shaft movably passes through the right end of the right cross bar and is fixedly connected to the right end of the baffle.

[0011] Preferably, the output end of the hydraulic cylinder movably passes through the upper wall of the L-shaped plate and is fixedly connected to the upper end of the hollow block, the upper inner wall of the hollow block is installed with a cylinder, the output end of the cylinder is fixedly connected with a ejector pin, and the lower end of the ejector pin is movably inserted into the lower end of the upper mold.

[0024] like Figure 1-Figure 4As shown, a construction stamping die comprises a base 1, a lower die 2 is installed at the front of the upper end of the base 1, a waste trough 15 is opened in the middle of the upper end of the base 1, an L-shaped plate 3 is installed at the rear of the upper end of the base 1, a hydraulic cylinder 4 is installed at the upper end of the L-shaped plate 3, and the hydraulic cylinder 4 is used to drive the upper die 7 to move, and two guide plates 5 symmetrically distributed on the upper wall of the L-shaped plate 3 are installed, a slidable hollow block 6 is installed between the two guide plates 5, an upper die 7 is installed at the lower end of the hollow block 6, and a driving component 10 is connected to the front end of the hollow block 6, a cross bar 11 is installed at the front end of the two guide plates 5, and a rotatable baffle 14 is installed between the two cross bars 11. The initial position of the baffle 14 is in an inclined state, and a rubber pad 13 is installed in the middle of the lower end of the baffle 14. The rubber pad 13 has good elasticity and buffering performance, which can provide a soft feeling when the hand touches the baffle 14, reduce the impact force between the hand and the baffle 14, and help reduce the possibility of injury.

[0025] When in use, the workpiece to be stamped is placed above the lower mold 2, and the hydraulic cylinder 4 is controlled to drive the hollow block 6 to move downward, and the hollow block 6 drives the upper mold 7 to move downward to stamp the mold. When the hollow block 6 moves downward, it drives the driving component 10 to move, and the driving component 10 drives the baffle 14 to rotate forward. When the baffle 14 rotates forward a certain angle, it pushes the worker's hand so that the worker's hand is away from the stamping area, reducing the risk of the stamping mechanical parts clamping the hand or causing injury, thereby improving safety performance.

[0026] In order to discharge the waste generated by the upper mold 7, a guide groove 12 is opened at the upper end of the baffle 14. The guide groove 12 is located above the upper mold 7. The guide groove 12 is located above the waste groove 15. When the upper mold 7 is reset after stamping, the waste in the upper mold 7 is ejected. At this time, the guide groove 12 is located below the waste. The waste slides into the waste groove 15 through the guide groove 12 and is discharged. There is no need for workers to manually collect the waste, which reduces the burden on workers.

[0027] The baffle 14 can be driven to rotate by the driving component 10, and the specific structure is: the driving component 10 includes a rack 101, the rack 101 is fixedly connected to the front right part of the hollow block 6, the rack 101 is fixedly connected to the hollow block 6 through an L-shaped block, the rack 101 is meshed with a gear 102, and a connecting shaft 103 is installed on the left end of the gear 102. The gear 102 is located on the right side of the right cross bar 11. When the upper mold 7 moves downward for stamping, the hollow block 6 drives the rack 101 to move downward, the rack 101 drives the gear 102 to rotate forward, and the gear 102 drives the baffle 14 to rotate forward through the connecting shaft 103. When the upper mold 7 moves upward to reset, the rack 101 drives the gear 102 to rotate backward, and the gear 102 drives the baffle 14 to rotate backward and reset through the connecting shaft 103.

[0028] In order to drive the baffle 14 to rotate, the left end of the connecting shaft 103 movably passes through the right end of the right cross bar 11 and is fixedly connected to the right end of the baffle 14 , and the baffle 14 rotates around the center of the connecting shaft 103 .

[0029] The output end of the hydraulic cylinder 4 movably passes through the upper wall of the L-shaped plate 3 and is fixedly connected to the upper end of the hollow block 6. The upper inner wall of the hollow block 6 is installed with a cylinder 8. The output end of the cylinder 8 is fixedly connected with an ejector pin 9. The lower end of the ejector pin 9 movably inserts into the lower end of the upper mold 7. The cylinder 8 and the ejector pin 9 cooperate to eject the waste material in the upper mold 7. When in use, when the upper mold 7 is reset, the output end of the cylinder 8 drives the ejector pin 9 to move downward to eject the waste material out of the upper mold 7.

[0030] Furthermore, the left end and the right end of the baffle 14 are in active contact with the ends of the two guide plates 5 that are close to each other.

[0031] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
