[0001] The utility model relates to the technical field of mold equipment, and more specifically, to a precisely positioned mold. Background Art

[0002] A mold is a forming device used to produce standardized industrial accessories. In the industrial production process, molds are mainly used to change the physical state of raw materials through injection molding, blow molding, die casting or forging, thereby realizing the processing of the shape of the object. Due to the wide use of molds, they have the title of "Mother of Industry".

[0003] In Chinese utility model patents, for example, the utility model of CN215544293U discloses a precisely positioned metal forming die. Through the cooperation between a connecting rod and a sleeve, and a pulley and a guide bar, the die has a precisely positioned setting, a simple structure, and is easy to operate.

[0004] However, the connecting rod and sleeve of the above technology will wear out after a long period of cooperation, resulting in a decrease in the guiding accuracy of the connecting rod. The worn connecting rod may no longer slide smoothly in the sleeve, and may become stuck or shaken, thereby affecting the precise positioning function of the mold. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a precisely positioned mold. The technical problem to be solved by the present invention is that the connecting rod and the sleeve will wear out after a long period of cooperation, resulting in a decrease in the guiding accuracy of the connecting rod. The sliding of the worn connecting rod in the sleeve may no longer be smooth, and may become stuck or shaken, thereby affecting the precise positioning function of the mold.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0008] like Figure 1-3 As shown, the specific implementation method is: by setting a liquid pumping mechanism, a liquid storage tank, a guide column, and a guide sleeve, the mold is assisted in positioning by the guide column and the guide sleeve. At the same time, the lubricating liquid in the liquid storage tank is extracted by the liquid pumping mechanism and the lubricating liquid is covered on the outside of each guide column through the liquid discharge tube, thereby reducing the friction between the guide column and the guide sleeve, thereby increasing the service life of the guide column and the guide sleeve, and ensuring the positioning accuracy of the mold.

[0009] In a preferred embodiment, each of the liquid pumping mechanisms includes a piston, and each piston is slidably connected to the corresponding liquid pumping box. A plurality of push rods are symmetrically installed on the bottom surface of the movable seat, and the top end of each push rod is fixedly connected to the corresponding piston. Each of the liquid pumping boxes is connected to the corresponding liquid storage box through an inlet pipe, and each of the liquid pumping boxes is connected to the corresponding liquid discharge cylinder through a discharge pipe. A first one-way valve is installed in each of the inlet pipe and the discharge pipe.

[0010] In a preferred embodiment, each of the internal circulation mechanisms includes multiple collecting seats, and each collecting seat is fixedly mounted on the bottom wall of the frame, and each guide column is located at the center of the collecting seat, and the outer side of each collecting seat is fixed and connected to a connecting pipe, and each connecting pipe is connected to the liquid storage tank at the corresponding position.

[0011] In a preferred embodiment, a baffle is fixedly installed in each of the liquid extraction boxes, and a through groove is formed in each of the baffles.

[0012] In a preferred embodiment, a second one-way valve is installed in each of the connecting pipes.

[0013] In a preferred embodiment, a sponge is fixedly mounted on the bottom end of each of the liquid discharge cylinders, and each sponge ring is arranged on the top end of a guide column at a corresponding position.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model sets a hydraulic cylinder, a movable seat, a push rod, a piston, a liquid inlet pipe, a liquid discharge pipe, a sponge and other devices, so that when the hydraulic cylinder drives the upper mold on the movable seat to process the workpiece, the reciprocating sliding of the movable seat pushes the push rod to drive the piston to slide back and forth in the liquid extraction box, thereby the lubricating liquid in the liquid storage tank in the smoking area is discharged into each liquid discharge tube. When the sponge absorption limit is reached, the sponge will overflow with the lubricating liquid, and the lubricating liquid will slide downward along the guide column, thereby reducing the friction between the guide column and the guide sleeve, thereby extending the service life of the guide column and the guide sleeve, ensuring the guiding accuracy of the upper mold, and at the same time, the push rod is mobilized to slide back and forth by the movable seat, thereby reducing the setting of the driving source, thereby reducing the manufacturing cost of the device.

[0016] 2. The utility model realizes that the lubricating liquid sliding down the guide column will fall into the collecting seat by setting the collecting seat and the second one-way valve. As the liquid extraction box slides back and forth, the lubricating liquid in the collecting seat is extracted into the liquid storage tank, thereby realizing the internal circulation of the lubricating liquid and avoiding the waste of the lubricating liquid.

[0017] To sum up, the utility model is easy to operate when in use, and can automatically apply lubricating liquid between each guide pin and guide sleeve, thereby reducing the friction between the guide pin and the guide sleeve, thereby extending the service life of the guide pin and the guide sleeve, ensuring the guiding accuracy of the upper mold, and at the same time realizing the internal circulation of the lubricating liquid to avoid waste of the lubricating liquid.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Reference Figure 1-3 The top of each guide post 5 is fixedly mounted with a liquid pump 14, and each guide post 5 is located at the center of the liquid pump 14 at the corresponding position, and each liquid pump 14 is connected to the liquid pump 12 at the corresponding position. The bottom end of each guide post 5 is provided with an internal circulation mechanism, and each internal circulation mechanism is connected to the liquid pump 6 at the corresponding position.

[0024] like Figure 1-3 As shown, the specific implementation method is: by setting a pumping mechanism, a liquid storage tank 6, a guide column 5, and a guide sleeve 8, the mold is assisted in positioning by the guide column 5 and the guide sleeve 8. At the same time, the lubricating liquid in the liquid storage tank 6 is extracted by the pumping mechanism and the lubricating liquid is covered on the outside of each guide column 5 through the drain cylinder 14, thereby reducing the friction between the guide column 5 and the guide sleeve 8, thereby increasing the service life of the guide column 5 and the guide sleeve 8, and ensuring the positioning accuracy of the mold.

[0025] Each pumping mechanism includes a piston 15, and each piston 15 is slidably connected to the corresponding pumping box 12. A plurality of push rods 11 are symmetrically installed on the bottom surface of the movable seat 3, and the top of each push rod 11 is fixedly connected to the corresponding piston 15. Each pumping box 12 is connected to the corresponding liquid storage tank 6 through an inlet pipe 13, and each pumping box 12 is connected to the corresponding liquid discharge tube 14 through a discharge pipe 17. A first one-way valve is installed in each inlet pipe 13 and discharge pipe 17. It is worth noting that the movable seat 3 is driven up and down by the hydraulic cylinder 2, and the piston 15 can be pushed to slide back and forth in the pumping box 12 through the push rod 11. At the same time, a first one-way valve is installed in the inlet pipe 13 and the discharge pipe 17, so that the flow direction of the lubricating fluid is fixed. The lubricating fluid in the liquid storage tank 6 is drawn into the pumping box 12 through the inlet pipe 13, and the lubricating fluid in the pumping box 12 is discharged to the discharge tube 14 through the discharge pipe 17.

[0026] Each internal circulation mechanism includes multiple collecting seats 9, and each collecting seat 9 is fixedly mounted on the bottom wall of the frame 1, and each guide column 5 is located at the center of the collecting seat 9. The outer side of each collecting seat 9 is fixed and connected with a connecting pipe 10, and each connecting pipe 10 is connected to the corresponding position of the liquid storage tank 6. The lubricating liquid sliding along the guide column 5 can be collected through the collecting seat 9.

[0027] A baffle 16 is fixedly installed in each liquid extraction box 12 , and a through groove is formed in each baffle 16 to prevent the piston 15 from blocking the connection of the liquid discharge pipe 17 .

[0028] A second one-way valve is installed in each connecting pipe 10 , and the lubricating liquid in the liquid storage tank 6 will not flow back into the collecting seat 9 through the second one-way valve.

[0029] A sponge 18 is fixedly mounted on the bottom end of each liquid discharge cylinder 14 , and each sponge 18 is arranged around the top end of the corresponding guide post 5 , so that the lubricating liquid can be evenly covered on the outside of the guide post 5 through the sponge 18 .

[0030] When the utility model is used, the hydraulic cylinder 2 is first activated to mobilize the movable seat 3 to move, so that the workpiece can be processed through the upper mold 7 and the guide column 5. At the same time, while the movable seat 3 moves back and forth, the push rod 11 can drive the piston 15 to slide back and forth in the liquid extraction box 12, and then the lubricating liquid in the liquid storage box 6 is extracted through the liquid inlet pipe 13, and discharged to each liquid discharge cylinder 14 through the liquid discharge pipe 17, and the lubricating liquid is absorbed by the sponge 18. When the absorption limit is reached, the sponge 18 will overflow the lubricating liquid, and the lubricating liquid will slide down along the guide column 5, thereby reducing the friction between the guide column 5 and the guide sleeve 8, thereby extending the service life of the guide column 5 and the guide sleeve 8 and ensuring the guiding accuracy of the upper mold 7;

[0031] At the same time, the lubricating liquid sliding down the guide column 5 will fall into the collecting seat 9, and as the liquid extraction box 12 slides back and forth, the lubricating liquid in the collecting seat 9 is extracted into the liquid storage box 6, thereby realizing the internal circulation of the lubricating liquid and avoiding the waste of the lubricating liquid.

It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
