Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a forming tool for hardware processing which can avoid waste oil back-absorption. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. In short, molds are tools used to shape objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material, and is known as the "mother of industry". It is a tool that makes the blank become a workpiece with a specific shape and size under the action of external force. The mold generally consists of two parts: the male mold and the female mold (or the male mold and the female mold), which can be separated or combined. When separated, the workpiece is taken out, and when closed, the blank is injected into the mold cavity for forming. The mold is a precision tool with a complex shape. It bears the expansion force of the blank. It has high requirements for structural strength, rigidity, surface hardness, surface roughness and processing accuracy. The development level of mold production is one of the important indicators of the level of mechanical manufacturing.

[0003] During the metal stamping and stretching process, a vacuum environment will be formed between the die and the product forming male. It is necessary to add an exhaust hole to release the vacuum environment and facilitate the mold opening. The existing exhaust method of the forming male for metal processing is to exhaust from the bottom when the mold is closed, but when the mold is opened, negative air pressure will be generated from the bottom to the mold core, and the waste residue and waste oil on the mold will be sucked back to the forming male.

[0004] Based on the above situation, the utility model provides a forming tool for hardware processing which can avoid the back-absorption of waste oil. Utility Model Content

[0006] A forming pin for hardware processing which can avoid waste oil back-absorption comprises a punch, a short pipeline, a lubricating mechanism and a cooling mechanism. The punch is fixedly connected with the short pipeline, the punch is provided with the lubricating mechanism and the punch is provided with the cooling mechanism.

[0007] As a further preferred scheme, the lubrication mechanism includes an oil tank, a large water pump, a connecting pipe, a branch pipe, a circular pipe, a reset spring and a round-headed rod. The punch is fixedly connected to the oil tank, the punch is fixedly connected to a pair of branch pipes, the punch is fixedly connected to a circular pipe, the oil tank is fixedly connected to the large water pump, the large water pump is fixedly connected to the connecting pipe, one end of the connecting pipe is connected to the water outlet of the large water pump, the other end of the connecting pipe is connected to the paired branch pipes, one end of the branch pipes is connected to the connecting pipe, the other end of the branch pipes is connected to the circular pipe, one end of the circular pipe is connected to the paired branch pipes, the other end of the circular pipe is connected to the outside of the punch, the punch is slidably connected to the round-headed rod, a reset spring is fixedly connected between the round-headed rod and the punch, and the round-headed rod is slidably connected to the circular pipe.

[0008] As a further preferred scheme, the cooling mechanism includes a water tank, a small water pump and a circulating water pipe. The punch is fixedly connected to the water tank, the water tank is fixedly connected to the small water pump, the punch is fixedly connected to the circulating water pipe, one end of the circulating water pipe is connected to the water outlet of the small water pump, and the other end of the circulating water pipe is connected to the water tank.

[0009] As a further preferred solution, it also includes a cylinder and a circular plate, the punch is fixedly connected to a pair of cylinders, the punch is slidably connected to the circular plate, and the output ends of the pair of cylinders are fixedly connected to the circular plate.

[0010] As a further preferred solution, the short pipe is an L-shaped pipe, which is used to prevent the negative pressure when the mold is opened from causing the waste residue and waste oil to be sucked back into the molding cylinder.

[0011] As a further preferred solution, the bottom of the circulating water pipe is designed as a multi-layer ring to quickly cool the punch.

[0012] The beneficial effects of the utility model are as follows: 1. The utility model uses short pipes and other components to release the vacuum environment between the punch and the mold when the molding rod for hardware processing is opened through the short pipe, and can also avoid the waste residue and waste oil on the mold being sucked back to the molding rod, thereby affecting the next processing.

[0013] 2. The utility model uses the oil tank, the round head rod and other components to enable the forming tool for hardware processing to add lubricating oil to the bottom of the punch, which is used to reduce friction and facilitate demoulding, while also extending the life of the mold and improving the surface quality of the product.

[0014] 3.

[0028] A forming rod for hardware processing to avoid waste oil back-absorption, such as Figure 1-Figure 7 As shown, it includes a punch 1, a short pipe 2, a lubricating mechanism and a cooling mechanism. The short pipe 2 is fixedly connected inside the punch 1, the lubricating mechanism is provided on the punch 1, and the cooling mechanism is provided on the punch 1.

[0029] like Figure 3-Figure 5 As shown, the lubrication mechanism includes an oil tank 3, a large water pump 4, a connecting pipe 5, a branch pipe 6, a circular pipe 7, a reset spring 8 and a round head rod 9. The oil tank 3 is fixedly connected to the left side of the top of the punch 1, a pair of branch pipes 6 are fixedly connected to the inside of the punch 1, a circular pipe 7 is fixedly connected to the inside of the punch 1, a large water pump 4 is fixedly connected to the bottom of the oil tank 3, a connecting pipe 5 is fixedly connected to the bottom of the large water pump 4, one end of the connecting pipe 5 is connected to the water outlet of the large water pump 4, the other end of the connecting pipe 5 is connected to the paired branch pipes 6, one end of the branch pipe 6 is connected to the connecting pipe 5, the other end of the branch pipe 6 is connected to the circular pipe 7, one end of the circular pipe 7 is connected to the paired branch pipes 6, the other end of the circular pipe 7 is connected to the outside of the bottom end of the punch 1, a round head rod 9 is slidably connected to the inside of the punch 1, a reset spring 8 is fixedly connected between the round head rod 9 and the punch 1, and the round head rod 9 is slidably connected to the circular pipe 7.

[0030] like Figure 6 and Figure 7 As shown, the cooling mechanism includes a water tank 10, a small water pump 11 and a circulating water pipe 12. The water tank 10 is fixedly connected to the right side of the top of the punch 1, the small water pump 11 is fixedly connected to the bottom of the water tank 10, and the circulating water pipe 12 is fixedly connected to the inside of the punch 1. One end of the circulating water pipe 12 is connected to the water outlet of the small water pump 11, and the other end of the circulating water pipe 12 is connected to the water tank 10.

[0031] like Figure 8 and 9 As shown, it also includes a cylinder 13 and a circular plate 14. The cylinders 13 are fixedly connected to the left and right sides of the punch 1. The circular plate 14 is slidably connected to the upper outer side of the punch 1. The output ends of the paired cylinders 13 are fixedly connected to the circular plate 14.

[0032] like Figure 2 As shown, the short pipe 2 is an L-shaped pipe, which is used to prevent the negative pressure when the mold is opened from causing the waste residue and waste oil to be sucked back into the molding cylinder.

[0033] like Figure 7 As shown, the bottom of the circulating water pipe 12 is a multi-layer ring design, which is used to quickly cool the punch 1.

[0034] When people want to use the forming tool for hardware processing to process products, first start the large water pump 4 to drive the lubricating oil in the oil tank 3 through the connecting pipe 5 and into the branch pipe 6. At this time, the bottom end of the round head rod 9 is separated from the round pipe 7, and the lubricating oil can enter the round pipe 7 from the branch pipe 6 and finally flow out from the bottom of the punch 1. Then turn off the large water pump 4 and drive the punch 1 downward through an external device. The downward movement of the punch 1 will drive the round head rod 9 to move downward until the round head rod 9 contacts the bottom mold, and the round head rod 9 will be squeezed by the mold to move upward until the bottom end of the round head rod 9 enters the round pipe 7 and the punch 1 fits with the mold, the reset spring 8 is immediately compressed, and then the punch 1 is driven upward through an external device and the cylinder 13 is started to drive the circular plate 14 to move downward. The downward movement of the circular plate 14 will squeeze the mold to assist in demolding. At this time, the punch A vacuum state will appear between 1 and the mold, and ventilation can be performed through the short pipe 2 to release the vacuum state. The existence of the round head rod 9 can block the circular pipe 7 to prevent the negative pressure from sucking the waste residue and oil at the bottom of the mold into the circular pipe 7. After the punch 1 is separated from the mold, the cylinder 13 is started to drive the circular plate 14 to move upward and reset, and the round head rod 9 moves downward and reset under the action of the spring reset and no longer blocks the circular pipe 7. When the punch 1 works for a long time and the temperature is high, the small water pump 11 can be started to drive the coolant in the water tank 10 to cool the bottom of the punch 1 through the circulating water pipe 12, and finally flow back to the water tank 10, and circulate water cooling in turn. When cooling is not required, the small water pump 11 can be turned off. The multi-layer ring design at the bottom of the circulating water pipe 12 can increase the contact area between the circulating water pipe 12 and the punch 1, thereby improving the cooling effect.

Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
