[0002] Molds are various molds and tools used in industrial production to produce desired products through methods such as injection molding, blow molding, extrusion, die-casting, forging, smelting, and stamping. Simply put, a mold is a tool used to create a shaped object. This tool is composed of various parts, and different molds are composed of different parts. It primarily achieves the desired shape by changing the physical state of the molded material. Punching holes in the mold requires a punching device.

[0003] The patent for a mold punching device with the announcement number CN221109964U includes a placement mechanism, a functional mechanism is placed in the middle of the upper surface of the placement mechanism, and the functional mechanism includes a functional plate and a second through hole, a support mechanism is fixedly connected to the middle of the upper surface of the placement mechanism, and a punching mechanism is fixedly connected to the middle of the upper surface of the support mechanism. This mold punching device, through the provision of the functional mechanism and the punching mechanism, solves the problem that existing mold punching devices, when in use, are usually only able to drill holes of a fixed size in the mold and cannot quickly adjust the size of the drilled holes according to actual use requirements; or that existing mold punching devices, after long-term use, will cause the drill bit structure to wear out. Existing drill bit structures usually use related connection structures and then cooperate with bolts and nuts to connect the drill bit structure, and this method is relatively inconvenient to disassemble and assemble the drill bit structure.

[0004] However, after the drilling is completed by the drill bit, it is inconvenient to discharge and collect the waste residue generated from the inside of the drill hole, so that the waste residue remaining in the mold drill hole affects subsequent processing and use.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of the utility model is to provide a mold punching device that can effectively solve the above technical problems.

[0007] In order to achieve the purpose of this utility model, the following technical solutions are adopted:

[0008] A mold punching device comprises: a punch body, a drilling slot provided on the punch body, and a clamping assembly provided on the punch body for fixing a punching mold;

[0009] The clamping assembly includes: clamping plates arranged on both sides of the punching machine body to fix the punching die, an electric push rod to drive the clamping plates to move, and a slag cleaning assembly arranged just below the drilling slot to blow slag from the punching die;

[0010] The slag cleaning assembly includes: an air blower fixedly mounted on the punch body, a piston rod movably mounted inside the air blower, a connecting plate fixedly mounted on the piston rod, and a hinged rod hingedly mounted on both sides of the connecting plate, one end of the hinged rod being hingedly mounted to the bottom of the adjacent clamping plate.

[0011] Furthermore, the punch body is symmetrically provided with sliding grooves, the bottom of the splint is fixedly mounted with a slider that matches the sliding groove on the punch body, and one end of the hinged rod is hingedly mounted on the slider at the bottom of the splint.

[0012] Furthermore, the air outlet of the air cylinder is a conical structure with a small upper portion and a large lower portion, and a filter is fixedly installed on the air outlet.

[0013] Furthermore, an air outlet pipe is symmetrically fixedly installed on the upper end of the air blow tube, and a connecting pipe is fixedly installed on one end of the air outlet pipe. The connecting pipe is fixedly installed on one side of the upper end of the punch body, and several air blowing heads are fixedly installed at equal intervals on the surface of the connecting pipe.

[0014] Furthermore, a discharge trough is symmetrically provided on the surface of the punch body, and a collection frame is placed on the inner bottom of the punch body, and the collection frame is located directly below the discharge trough.

[0015] Compared with the prior art, the utility model has the following beneficial effects: through the arrangement of components such as the clamping assembly, the slag cleaning assembly and the collection frame, after the drilling is completed, when the two clamps move away from each other, the piston rod squeezes the air inside the blow cylinder, and the squeezed air blows out the waste slag inside the mold drilling hole, avoiding the drilling waste slag remaining in the drill hole and affecting subsequent processing and use. At the same time as the gas is discharged, the blow head blows the slag on the table from the discharge trough to the collection frame at the bottom of the punch body for collection, reducing manual cleaning and reducing the labor intensity of the staff.

[0023] like Figures 1 to 3 As shown, the utility model is a mold punching device, comprising: a punch body 1, a drilling slot 101 provided on the punch body 1, and a clamping assembly 2 provided on the punch body 1 to fix the punching mold;

[0024] The clamping assembly 2 includes: a clamping plate 201 arranged on both sides of the punching machine body 1 to fix the punching die, a slide groove is symmetrically opened on the punching machine body 1, and a slider that matches the slide groove on the punching machine body 1 is fixedly installed at the bottom of the clamping plate 201. One end of the hinged rod 304 is hingedly installed on the slider at the bottom of the clamping plate 201. When the two clamping plates 201 approach or move away from each other, the clamping plate 201 pushes the hinged rod 304 hinged at the bottom to deflect, so that the connecting plate 303 drives the piston rod 302 inside the blowing cylinder 301 to move up and down, squeezing the gas inside the blowing cylinder 301 to achieve slag blowing, and the electric push rod 202 that drives the clamping plate 201 to move, and a slag cleaning assembly 3 arranged just below the drilling slot 101 to blow slag from the punching die;

[0025] The slag cleaning component 3 includes: a blow cylinder 301 fixedly mounted on the punching machine body 1, the air outlet of the blow cylinder 301 is a conical structure with a small top and a large bottom, and a filter screen 305 is fixedly mounted on the air outlet. Through the conical structure air outlet with a small top and a large bottom, the gas flow rate can be accelerated when the gas is squeezed and discharged, thereby increasing the impact force of the gas on the waste residue inside the mold drilling hole, which is convenient for cleaning the waste residue inside the drilling hole, and the filter screen 305 is set to block the fallen waste residue and prevent it from falling into the blow cylinder 301, a piston rod 302 movably mounted inside the blow cylinder 301, a connecting plate 303 fixedly mounted on the piston rod 302, and the top of the connecting plate 303 is set as an inclined surface, which is convenient for the blown waste residue to fall into the collection frame 4, thereby preventing the waste residue from accumulating on the surface of the connecting plate 303 and affecting its use, and a hinged rod 304 hingedly mounted on both sides of the connecting plate 303, one end of the hinged rod 304 is hingedly mounted to the bottom of the adjacent splint 201.

[0026] When punching a hole in the mold, the mold is placed on the table of the punching machine body 1, and the electric push rods 202 are started. The two electric push rods 202 simultaneously push the corresponding clamping plates 201 to the side of the mold to clamp and fix the mold to be drilled. When the clamping plates 201 move, the slider at the bottom of the clamping plates 201 drives the hinged hinge rod 304 to deflect, so that the hinge rod 304 pushes the piston rod 302 fixed on the top of the connecting plate 303 to descend, so that the inside of the blowing cylinder 301 is filled with air. After the drilling is completed, the two clamping plates 201 move away from each other. At this time, the hinged hinge rod 304 at the bottom of the clamping plates 201 is hinged. The piston rod 302 on the connecting plate 303 is driven to move upward, so that the piston rod 302 squeezes the air inside the blow cylinder 301, and the squeezed air is discharged from the air outlet on the top of the blow cylinder 301, and blows out the waste residue inside the mold drilling through the drilling groove 101, so as to avoid the drilling waste residue remaining in the drilling hole and affecting subsequent use. At the same time, the exhaust gas passes through the air outlet pipe 3011, passes through the connecting pipe 3012 and is blown out from the blowing head 3013, and blows the residue on the table from the discharge groove 102 to the collection frame 4 at the bottom of the punching machine body 1 for collection, thereby reducing manual cleaning and reducing the labor intensity of the staff.

[0027] An air outlet pipe 3011 is symmetrically fixedly mounted on the upper end of the air blow cylinder 301, and a connecting pipe 3012 is fixedly mounted on one end of the air outlet pipe 3011. The connecting pipe 3012 is fixedly mounted on one side of the upper end of the punch body 1. Several air blow heads 3013 are fixedly mounted on the surface of the connecting pipe 3012 at equal intervals. When the piston rod 302 squeezes the air inside the air blow cylinder 301 and cleans the waste residue inside the mold drilling through the drilling groove 101, the gas passes through the air outlet pipe 3011, passes through the connecting pipe 3012, and is blown out from the air blow head 3013, blowing the waste residue on the table from the discharge groove 102 to the collection frame 4 at the bottom of the punch body 1 for collection.

[0028] The surface of the punch body 1 is symmetrically provided with a discharge trough 102, and a collection frame 4 is placed on the inner bottom of the punch body 1, and the collection frame 4 is located just below the discharge trough 102. The collection frame 4 can collect the blown-down waste residue to improve the cleanliness of the processing table.

[0029] Working principle: Turn on the power, when punching the mold, place the mold on the table of the punching machine body 1, start the electric push rod 202, and the two electric push rods 202 simultaneously push the corresponding clamping plates 201 to the side of the mold to clamp and fix the mold to be drilled. When the clamping plates 201 move, the slider at the bottom of the clamping plates 201 drives the hinged hinge rod 304 to deflect, so that the hinge rod 304 pushes the piston rod 302 fixed on the top of the connecting plate 303 to descend, so that the inside of the blowing cylinder 301 is filled with air. After the drilling is completed, the two clamping plates 201 move away from each other. The hinged rod 304 hinged at the bottom of the splint 201 drives the piston rod 302 on the connecting plate 303 to move upward, so that the piston rod 302 squeezes the air inside the blow cylinder 301, and the squeezed air is discharged from the air outlet on the top of the blow cylinder 301, and blows out the waste residue inside the mold drilling through the drilling groove 101, so as to avoid the drilling waste residue remaining in the drilling hole and affecting subsequent use. At the same time, the exhaust gas passes through the outlet pipe 3011, passes through the connecting pipe 3012 and is blown out from the blowing head 3013, and blows the slag on the table from the discharge groove 102 to the collection frame 4 at the bottom of the punching machine body 1 for collection.
