Description

Technical Field

[0001] The utility model relates to the technical field of mold manufacturing, in particular to an automatic combined mold manufacturing device. Background Art

[0002] With the development of industrial technology, molds are used more and more widely, and the use of molds is becoming more and more inclined to automation. An automatic combined mold manufacturing device is a device that can automatically process molds, and generally uses drilling and milling methods for processing.

[0003] The prior art such as the publication number CN208729337U provides an automatic combined mold manufacturing device, including a base, a fixing frame and an electric control box. The upper outer surface of the base is fixedly installed with a fixing plate. A motor is installed on one side of the fixing plate away from the base, and a lead screw is installed on one side of the fixing plate close to the base. The upper outer surface of the fixing frame is fixedly installed with a cross beam. A motor base is movably installed on the outer surface of the cross beam. A crawler is installed on one side of the motor base. A connecting head is provided on the front outer surface of the motor base. A drill bit is fixedly connected to the lower end of the connecting head. A water pipe is connected to the lower end of the motor base at a position on one side of the drill bit. A baffle is provided at the position between the fixing frames on the upper end of the base. A workbench is provided inside the baffle at the position on the upper end of the base. The utility model can facilitate the operation and use of the device and make the device more energy-saving and environment-friendly, and has practicability.

[0004] In the processing process of this solution, the drill bit will entangle metal chips. This is mainly because high temperature and high pressure are generated at the head of the drill bit during drilling, which causes the metal molecules on the material surface to change, forming iron chips. If the iron chips cannot be effectively cut or curled, they may entangle on the tool, such as the drill bit, which will lead to difficult processing and easy breakage of the drill bit. In view of this, we propose an automatic combined mold manufacturing device. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an automatic combined mold manufacturing device, which solves the problem that when the iron chips cannot be effectively cut or curled, they may entangle on the drill bit and affect the processing.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] An automated combined die manufacturing device includes a connecting seat. A main shaft rotates at the bottom of the connecting seat. A cutter is connected to the inside of the main shaft through a tool holder. A cutting mechanism is arranged below the connecting seat. The cutting mechanism includes a first support ring. The first support ring is fixedly connected to the bottom of the connecting seat. A first bevel gear is rotatably connected to the outer wall of the first support ring. A third bevel gear is meshed and connected below the first bevel gear, and the third bevel gear is rotatably connected to the bottom of the first support ring. A second bevel gear is meshed and connected below the third bevel gear. The second bevel gear is fixedly connected to the outer wall of the main shaft. A first support rod is connected to the first bevel gear. A second support rod is connected to the second bevel gear. Cutting knives are respectively arranged at the corresponding positions of the first support rod and the second support rod. While the main shaft drives the cutter to rotate for processing, it will drive the second bevel gear to rotate. Through the meshed third bevel gear, the first bevel gear is driven to rotate, so that the cutting knives on the first support rod and the second support rod are driven by the second bevel gear and the first bevel gear to rotate in opposite directions, so that a shearing force is generated when the two groups of cutting knives rotate, and the iron chips generated by milling are cut, so that they are broken into pieces and it is difficult to form continuous iron chips, so as to avoid the situation of iron chips winding around the cutter. And the shearing force generated by the two cutting knives will increase significantly every time they cross, so that it can better break the iron chips.

[0008] Preferably, chutes are respectively opened at the corresponding positions of the first support rod and the second support rod. Sliders are slidably connected to the chutes, and the sliders are connected to the cutting knives at the corresponding positions. By setting the sliders to be slidably connected to the chutes, the length of the cutting knives extending out can be adjusted to adapt to the length of the cutter cutting.

[0009] Preferably, limiting grooves are opened at the corresponding positions of the sliders. A limiting slip ring is arranged between the sliders, and the limiting slip ring is slidably connected to the inner wall of the limiting groove. By sliding the limiting slip ring on the inner wall of the limiting groove on the slider, it can be ensured that the positions of the two groups of sliders are consistent while rotating in opposite directions, so as to facilitate cutting.

[0010] Preferably, a cooling mechanism is arranged below the main shaft. The cooling mechanism includes an annular cavity. The annular cavity is arranged below the main shaft. Water pipes are respectively connected to both sides of the top of the annular cavity. A sliding buckle is slidably connected to the outer wall of the water pipe, and the sliding buckle is connected to the outer wall of the connecting seat. A first spray head is connected to the bottom of the annular cavity. Coolant is introduced through the water pipe. The coolant passes through the annular cavity and is sprayed out from the first spray head to facilitate cooling the position where the cutter is processed, so as to avoid tool damage caused by high temperature.

[0011] Preferably, a second support ring is rotatably connected to the inner wall of the annular cavity. A connecting rod is connected to the inner wall of the second support ring. The connecting rod is connected to the slider at the corresponding position through a through groove. By connecting the slider through the connecting rod, the annular cavity and the slider move together, so as to conveniently adjust the length of the cutting tool protruding according to the cutting depth.

[0012] Preferably, a second spray head is connected to the bottom of the annular cavity. The first spray head and the second spray head are arranged in a staggered manner.

[0013] Preferably, the first spray head is inclined towards the tool, and the second spray head is vertically arranged. By arranging the first spray head inclined towards the tool, it is convenient to spray coolant to cool the tool during processing, and the sprayed coolant will wash away the cut iron filings, preventing them from accumulating at the cutting position of the tool. The second spray head flushes the iron filings to a farther position. Since the second spray head is vertically arranged, the second spray head sprays coolant under high pressure, generating a reaction force on the annular cavity, which cooperates with the weight of the annular cavity itself, so that the second spray head always maintains a certain distance from the surface of the workpiece being processed. This is convenient for automatically adjusting the direction of the coolant sprayed by the first spray head on the annular cavity to always face the position where the tool is processing according to the cutting depth, and enables the annular cavity to drive the slider to move together, so as to conveniently adjust the length of the cutting tool protruding according to the cutting depth.

[0014] By means of the above technical solution, the present utility model provides an automated combined mold manufacturing device, which at least has the following beneficial effects:

[0015] First, while the main shaft drives the tool to rotate for processing, it drives the second helical gear to rotate. Through the meshing third helical gear, the first helical gear is driven to rotate, so that the cutting tools on the first support rod and the second support rod are driven to rotate in opposite directions by the second helical gear and the first helical gear. When the two groups of cutting tools rotate, a shearing force is generated to cut the iron filings generated by milling, breaking them into pieces so that it is difficult to form continuous iron filings, thus avoiding the situation of iron filings winding around the tool. Moreover, the shearing force generated by the two groups of cutting tools increases significantly each time they cross, enabling better crushing of the iron filings.

[0016] Second, the present utility model is provided by inclining the first nozzle towards the tool, so as to facilitate the ejection of coolant for cooling the tool during processing, and the ejected coolant will wash away the cut iron filings, preventing them from accumulating at the cutting position of the tool. The second nozzle flushes the iron filings to a farther position. Since the second nozzle is vertically arranged, the second nozzle ejects coolant under high pressure, generating a reaction force on the annular cavity, which cooperates with the weight of the annular cavity itself, so that the second nozzle always maintains a certain distance from the surface of the workpiece being processed, facilitating the automatic adjustment of the direction of the coolant sprayed by the first nozzle on the annular cavity towards the tool processing position according to the depth of the tool cutting, and enabling the annular cavity to drive the slider to move together, so as to facilitate the automatic adjustment of the length of the cutting tool protruding according to the cutting depth.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment 1

[0024] An automated combined mold manufacturing device, as Figures 1-4 shown, includes a connecting seat 1. A main shaft 11 is rotatably connected to the bottom of the connecting seat 1. A tool 12 is connected to the inside of the main shaft 11 through a tool holder 121. A cutting mechanism 2 is arranged below the connecting seat 1. The cutting mechanism 2 includes a first support ring 211. The first support ring 211 is fixedly connected to the bottom of the connecting seat 1. A first bevel gear 21 is rotatably connected to the outer wall of the first support ring 211. A third bevel gear 23 is meshed and connected below the first bevel gear 21. And the third bevel gear 23 is rotatably connected to the bottom of the first support ring 211. A second bevel gear 22 is meshed and connected below the third bevel gear 23. The second bevel gear 22 is fixedly connected to the outer wall of the main shaft 11. A first support rod 24 is connected to the first bevel gear 21. A second support rod 25 is connected to the second bevel gear 22. Cutting knives 28 are respectively arranged at the corresponding positions of the first support rod 24 and the second support rod 25. While the main shaft 11 drives the tool 12 to rotate for processing, it will drive the second bevel gear 22 to rotate. Through the meshed third bevel gear 23, the first bevel gear 21 is driven to rotate, so that the cutting knives 28 on the first support rod 24 and the second support rod 25 are driven by the second bevel gear 22 and the first bevel gear 21 to rotate in opposite directions, so that a shearing force is generated when the two groups of cutting knives 28 rotate, and the iron chips generated by milling are cut, so that they are broken into pieces and it is difficult to form continuous iron chips, so as to avoid the situation that the iron chips wind around the tool 12. And the shearing force generated by the two groups of cutting knives 28 will increase significantly every time they cross, so that the iron chips can be better broken. Sliding grooves 26 are respectively opened at the corresponding positions of the first support rod 24 and the second support rod 25. Sliders 27 are slidably connected to the sliding grooves 26. And the sliders 27 are connected to the cutting knives 28 at the corresponding positions. By setting the sliders 27 to be slidably connected to the sliding grooves 26, the length of the cutting knives 28 extending out can be adjusted to adapt to the cutting length of the tool 12. Limit grooves 291 are opened at the corresponding positions of the sliders 27. A limit sliding ring 29 is arranged between the sliders 27. And the limit sliding ring 29 is slidably connected to the inner wall of the limit groove 291. By sliding the limit sliding ring 29 on the inner wall of the limit groove 291 on the slider 27, when the two groups of sliders 27 rotate in opposite directions, the positions between them can be guaranteed to be consistent, so as to facilitate cutting.

[0025] In this embodiment, while the main shaft 11 drives the tool 12 to rotate for machining, it will drive the second helical gear 22 to rotate. The third helical gear 23 that meshes with the second helical gear 22 drives the first helical gear 21 to rotate, causing the cutting knives 28 on the first support rod 24 and the second support rod 25, which are driven and connected by the second helical gear 22 and the first helical gear 21, to rotate in opposite directions. As a result, when the two sets of cutting knives 28 rotate, a shearing force will be generated to cut the iron chips produced by milling, breaking them into fragments and making it difficult for continuous iron chips to form, so as to avoid the situation of iron chips winding around the tool 12. Moreover, when the two sets of cutting knives 28 cross each time, the shearing force generated will increase significantly, enabling it to better break the iron chips. Embodiment 2

[0026] As Figure 2 shown, a cooling mechanism 3 is provided below the main shaft 11. The cooling mechanism 3 includes an annular cavity 31. The annular cavity 31 is arranged below the main shaft 11. Both sides of the top of the annular cavity 31 are respectively connected with water pipes 32. The outer wall of the water pipe 32 is slidably connected with a sliding buckle 321, and the sliding buckle 321 is connected with the outer wall of the connecting seat 1. The bottom of the annular cavity 31 is connected with a first nozzle 311. By introducing coolant through the water pipe 32, the coolant passes through the annular cavity 31 and sprays out from the first nozzle 311 to facilitate cooling the position where the tool 12 is machining, so as to avoid damage to the tool 12 caused by high temperature. The inner wall of the annular cavity 31 is rotatably connected with a second support ring 33. The inner wall of the second support ring 33 is connected with a connecting rod 34. The connecting rod 34 is connected with the slider 27 at the corresponding position through a through groove 341. By connecting the slider 27 through the connecting rod 34, the annular cavity 31 and the slider 27 move together to facilitate adjusting the length of the cutting knife 28 extending out according to the cutting depth. The bottom of the annular cavity 31 is connected with a second nozzle 312. The first nozzle 311 and the second nozzle 312 are arranged in a staggered manner. The first nozzle 311 is inclined towards the tool 12, and the second nozzle 312 is vertically arranged. By arranging the first nozzle 311 inclined towards the tool 12, it is convenient to spray coolant to cool the tool 12 during machining, and the sprayed coolant will wash away the cut iron chips, preventing them from accumulating at the cutting position of the tool 12. The second nozzle 312 flushes the iron chips to a farther position. And because the second nozzle 312 is vertically arranged, the second nozzle 312 sprays coolant at high pressure, generating a reaction force on the annular cavity 31, which cooperates with the weight of the annular cavity 31 itself, so that the second nozzle 312 always maintains a certain distance from the surface of the workpiece being machined, facilitating automatically adjusting the direction of the coolant sprayed by the first nozzle 311 on the annular cavity 31 to always face the machining position of the tool 12 according to the cutting depth of the tool 12, and enabling the annular cavity 31 to drive the slider 27 to move together to facilitate automatically adjusting the length of the cutting knife 28 extending out according to the cutting depth.

[0027] In this embodiment, the first nozzle 311 is inclined towards the tool 12 to facilitate spraying coolant for cooling the tool 12 during machining, and the sprayed coolant will wash away the cut iron chips, preventing them from accumulating at the cutting position of the tool 12. The second nozzle 312 flushes the iron chips to a farther position, further ensuring the cleanliness of the machining position. Since the second nozzle 312 is vertically arranged, the second nozzle 312 ejects coolant under high pressure, generating a reaction force on the annular cavity 31, which cooperates with the weight of the annular cavity 31 itself. By connecting the slider 27 through the connecting rod 34, the annular cavity 31 and the slider 27 move together, enabling the second nozzle 312 to always maintain a certain distance from the surface of the workpiece being machined, so as to conveniently adjust the direction of the coolant sprayed by the first nozzle 311 on the annular cavity 31 to always face the machining position of the tool 12 according to the cutting depth of the tool 12, and enabling the annular cavity 31 to drive the slider 27 to move together, so as to conveniently adjust the length of the cutting tool 28 protruding according to the cutting depth.

[0028] When the automated combined mold manufacturing equipment of the present utility model is in use, while the main shaft 11 drives the tool 12 to rotate for machining, it will drive the second helical gear 22 to rotate. Through the meshing third helical gear 23, the first helical gear 21 is driven to rotate, causing the cutting tools 28 on the first support rod 24 and the second support rod 25 to rotate in opposite directions under the drive of the second helical gear 22 and the first helical gear 21. Shearing forces are generated when the two groups of cutting tools 28 rotate, cutting the iron chips generated by milling, breaking them into fragments and making it difficult to form continuous iron chips, so as to avoid the situation of iron chips winding around the tool 12. Moreover, the shearing forces generated by the two groups of cutting tools 28 will increase significantly each time they cross, enabling better crushing of the iron chips. The first nozzle 311 is inclined towards the tool 12 to facilitate spraying coolant for cooling the tool 12 during machining, and the sprayed coolant will wash away the cut iron chips, preventing them from accumulating at the cutting position of the tool 12. The second nozzle 312 flushes the iron chips to a farther position, further ensuring the cleanliness of the machining position. Since the second nozzle 312 is vertically arranged, the second nozzle 312 ejects coolant under high pressure, generating a reaction force on the annular cavity 31, which cooperates with the weight of the annular cavity 31 itself. By connecting the slider 27 through the connecting rod 34, the annular cavity 31 and the slider 27 move together, enabling the second nozzle 312 to always maintain a certain distance from the surface of the workpiece being machined, so as to conveniently adjust the direction of the coolant sprayed by the first nozzle 311 on the annular cavity 31 to always face the machining position of the tool 12 according to the cutting depth of the tool 12, and enabling the annular cavity 31 to drive the slider 27 to move together, so as to conveniently adjust the length of the cutting tool 28 protruding according to the cutting depth.
