Through the set guide assembly 6, the fixed mold assembly 5 can push out the remaining material and the finished material at the same time when the mold is opened, and under the auxiliary guiding action of the guide assembly 6, the finished material and the remaining material can be transmitted in different areas. The finished material is transmitted by the guide assembly 6 to the inside of the storage box 7 for storage, and the remaining material is transmitted by the guide assembly 6 to the outside of the device, thereby avoiding the situation where the finished material and the remaining material cannot be processed in different areas, resulting in a decrease in subsequent processing efficiency.

[0018] Embodiment 2: Based on Embodiment 1, this embodiment is for achieving the purpose of pushing the excess material out of the device during the mold opening process of the stamping process.

[0019] For details, see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The movable mold assembly 3 includes a mounting plate 31 that is slidably connected to the left side wall and the right side wall of the inner surface of the shell 2. The ends of the two mounting plates 31 that are close to each other are commonly fixedly connected to a movable mold plate 32. A plurality of stamping columns 33 are fixedly connected to the lower end of the movable mold plate 32 in an array. Racks 34 are slidably connected to the edges of the left side wall and the right side wall of the inner surface of the shell 2. The upper ends of the two racks 34 are respectively fixedly connected to the lower ends of the mounting plates 31 on the same side.

[0020] Furthermore, the output end of the hydraulic cylinder 4 is fixedly connected with a piston rod, which passes through the upper end of the housing 2 and is fixedly connected to the middle part of the upper end of the movable template 32 .

[0021] Furthermore, the fixed mold assemblies 5 include fixed blocks 51 fixedly connected at the middle of the left side wall of the inner surface of the shell 2 and the middle of the right side wall of the inner surface, the ends of the two fixed blocks 51 close to each other are commonly fixedly connected to the fixed mold plate 50, and the upper end of the fixed mold plate 50 is provided with a plurality of punching holes 501 distributed in an array, the rear ends of the two fixed blocks 51 are rotatably connected to gears 52, the upper ends of the two fixed blocks 51 are provided with special-shaped grooves 53, the front side walls of the inner surfaces of the two special-shaped grooves 53 and the rear side walls of the inner surfaces are commonly rotatably connected to threaded rods 54, the rear ends of the threaded rods 54 on the same side penetrate the front side walls of the inner surfaces of the special-shaped grooves 53 on the same side and are fixedly connected to the front ends of the gears 52 on the same side, the outer surfaces of the two threaded rods 54 are threadedly connected to threaded sleeves 55, the two threaded sleeves 55 are respectively slidably connected to the inner surfaces of the special-shaped grooves 53 on the same side, the upper ends of the two threaded sleeves 55 are commonly fixedly connected to a round plate 56, and the lower ends of the round plate 56 are fixedly connected to a push plate 57.

[0022] Furthermore, the two threaded rods 54 are respectively meshed with the two racks 34 , and the plurality of punching holes 501 and the plurality of punching columns 33 are arranged vertically and parallelly.

[0023] By starting the hydraulic cylinder 4, the piston rod fixedly connected to the output end of the hydraulic cylinder 4 drives the movable plate 32 fixedly connected thereto to move upward. When the movable plate 32 moves upward, since both left and right ends thereof are fixedly connected with the mounting plates 31, and the two mounting plates 31 are respectively slidably connected to the left and right inner surface walls of the housing 2, the mounting plates 31 on both sides also move upward accordingly. As can be seen from the above, the two threaded rods 54 are respectively meshed with the two racks 34. Therefore, when the mounting plates 31 on the same side drive the racks 34 on the same side to move upward, the gears 52 on both sides can be driven to move upward simultaneously. When the two gears 52 rotate, the threaded sleeves 55 are threadedly connected to the outer surface of the threaded rod 54 fixed thereto, and the two threaded sleeves 55 are respectively slidably connected to the inner surface of the special-shaped groove 53 on the same side. Therefore, when the gears 52 on both sides rotate, the threaded rods 54 on both sides can drive the threaded sleeves 55 threadedly connected to the outer surface thereof to slide forward on the inner surface of the special-shaped groove 53 corresponding thereto, and the return plate 56 is fixedly connected to the upper ends of the two threaded sleeves 55, so the return plate 56 also moves forward accordingly, so that the return plate 56 can push out the excess material generated during processing during the mold opening process; If the above operation is reversed, the mold closing process will be performed. As can be seen from the above, the plurality of punching holes 501 and the plurality of punching columns 33 are arranged in parallel up and down. Therefore, when the mold is closed, the movable plate 32 can drive the plurality of punching columns 33 fixedly connected at the lower end thereof to slide into the corresponding punching holes 501, and then the material can be punched and formed, and the formed material will fall from the plurality of punching holes 501 to the guide assembly 6 for storage; The piston rod and hydraulic cylinder 4 mentioned above are conventional settings in the prior art, wherein the piston rod only needs to be fixedly connected to the output end of the hydraulic cylinder 4 and to the upper end of the movable template 32 to facilitate subsequent driving. Therefore, the piston rod and the hydraulic cylinder 4 are conventional designs in the prior art, and their specific shapes, specific installation methods, circuit connection methods and control methods are all conventional designs, which will not be elaborated in detail in the present invention.

[0024] Embodiment 3: This embodiment is based on embodiment 2 and is for achieving the purpose of regional transmission and storage of finished materials and residual materials.

[0025] For details, see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The guide assembly 6 includes a material storage box 61 to which the lower ends of the two special-shaped grooves 53 are fixedly connected. A guide groove 62 is provided at the lower part of the left wall and the lower part of the right wall of the inner surface of the material storage box 61. The guide grooves 62 on the same side penetrate the material storage box 61. A triangular fixing plate 63 is fixedly connected at the front edge of the left end and the front edge of the right end of the material storage box 61. An inclined plate 1 64 is fixedly connected at one end of the two triangular fixing plates 63 close to each other. An inclined plate 2 65 is fixedly connected at the lower end of the inclined plate 1 64. The inclined plate 1 64 and the inclined plate 2 65 are arranged in a shape of 〉.

[0026] Furthermore, the outer surface of the circular plate 56 is slidably connected to the inner surfaces of the two guide grooves 62 , and the lower end of the push plate 57 is in contact with the bottom wall of the material storage box 61 .

[0027] Furthermore, the upper edge of the inclined plate 64 and the upper front edge of the fixed mold plate 50 are in contact with each other.

[0028] When the finished material formed by stamping falls from the plurality of punching holes 501 into the inner cavity of the material storage box 61, it can be known from the above that the outer surface of the return plate 56 is slidably connected to the inner surfaces of the two guide grooves 62, and the lower end of the push plate 57 is in contact with the bottom wall of the material storage box 61. Therefore, in the above operation, when the return plate 56 moves forward, the upper side of the return plate 56 can not only push out the residual material left during stamping, but the push plate 57 fixedly connected to the lower end of the return plate 56 can also be in contact with the bottom wall of the material storage box 61 to push out the finished material stored in the inner cavity of the material storage box 61; As can be seen from the above, the inclined plate 1 64 and the inclined plate 2 65 are arranged in a "〉 shape, and the upper edge of the inclined plate 1 64 is in contact with the upper front edge of the fixed template 50. Therefore, when the residual material is pushed out, the residual material can only slide outward from the upper end of the inclined plate 1 64, and the finished material will be pushed to the upper side of the inclined plate 2 65 by the push plate 57, and then slide to the upper side of the storage box 7, and fall into the inner cavity of the storage box 7 for storage, thereby achieving the purpose of transferring and storing the finished material and the residual material in different areas, thereby improving the subsequent stamping efficiency.

[0029] It should be noted that the specific installation method of the hydraulic cylinder 4, the circuit connection method and the control method used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0030] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
