Detailed implementation manners

[0023] To make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific implementation manners of the present utility model will be given in conjunction with the accompanying drawings of the specification.

[0024] Referring to Figures 1-4 , which is the first embodiment of the present utility model, a mold for a star-shaped sleeve is provided. This mold for a star-shaped sleeve includes a lower mold 1, an upper mold 2 located on the top of the lower mold 1, a guide post 3 fixed on the surface of the lower mold 1. The upper mold 2 is connected to the lower mold 1 through the guide post 3, the upper mold 2 is movably connected to the guide post 3, a top plate 4 fixed on the top of the guide post 3, an external driving force such as a hydraulic cylinder etc. (not shown in the figure) is installed at the bottom of the top plate 4 and on the top of the upper mold 2. A lubricating part 5 is installed on the surface of the top plate 4, and a demolding part 6 is installed inside the lower mold 1;

[0025] The lubricating part 5 includes an oil barrel 51 installed on the surface of the top plate 4. A partition plate 52 is fixedly connected inside the oil barrel 51. An electromagnetic valve 53 is installed inside the partition plate 52. A sleeve 54 is fixedly connected inside the partition plate 52. The top of the sleeve 54 is fixedly connected to the top of the oil barrel 51 to ensure the stability of the sleeve 54. The oil barrel 51 is provided in a transparent shape for observing the lubricating oil situation inside it. At the same time, an oil hole for refueling is installed at the top of the oil barrel 51.

[0026] Inside the sleeve 54, a pressure rod 55 is movably sleeved. One end of the pressure rod 55 extends to the top of the oil barrel 51. Equally spaced sealing rings 56 are fixedly installed on the outer surface of the pressure rod 55. The sealing rings 56 are in contact with the inner wall of the sleeve 54, which can facilitate the generation of pressure inside the sleeve 54 so as to evenly flow the lubricating oil between the oil barrel 51 and the partition plate 52 into the four oil delivery pipes 59.

[0027] On the top of the oil barrel 51, two air rods 57 are installed and are respectively located on both sides of the pressure rod 55. The top of the air rod 57 is fixedly connected to the bottom side of the pressure rod 55, which can make the pressure rod 55 have elasticity and at the same time ensure the stability of the pressure rod 55.

[0028] Through holes 58 are opened at the bottom of the sleeve 54. The through holes 58 are arranged in an annular array to generate pressure on the lubricating oil between the oil barrel 51 and the partition plate 52. At the same time, the four through holes 58 are all close to the four oil delivery pipes 59, which can assist in the uniformity of oil delivery.

[0029] Annularly arrayed oil delivery pipes 59 are fixedly connected inside the oil barrel 51. The oil delivery pipes 59 are located between the oil barrel 51 and the partition plate 52. The oil delivery pipes 59 are L-shaped. The other end of the oil delivery pipe 59 penetrates through the top plate 4 and extends into the inside of the guide post 3 and is fixedly connected to it for the delivery of lubricating oil.

[0030] A flow groove 591 is opened inside the guide post 3. One end of the oil delivery pipe 59 is located inside the flow groove 591 and is fixedly connected to it;

[0031] Annularly arrayed grooves 592 are opened on the outer surface of the guide post 3. Oil outlet holes 593 are arranged at equal intervals on the inner surface of the groove 592. The oil outlet holes 593 communicate with the flow groove 591 for the flow of lubricating oil. The inner side of the upper die 2 is located on the surface of the oil outlet holes 593, which can facilitate the contact of the lubricating oil and make the lubricating oil on the surface of the guide post 3 more uniform. The setting of the groove 592 can make the upper die 2 lift more stably.

[0032] The demolding part 6 includes an electric push rod 61 fixed inside the lower die 1. The output end of the electric push rod 61 is fixedly connected with a top plate 62. The top plate 62 is in close contact with the inside of the lower die 1, which can prevent circular patterns from appearing on the star sleeve during processing.

[0033] During the use process, place the sheet metal part on the surface of the lower die 1, and push the upper die 2 through an external hydraulic cylinder to move the upper die 2 towards the surface of the lower die 1 through the guide post 3 until it is completely in contact with the lower die 1, then the processing of the star sleeve can be completed;

[0034] When it is necessary to add lubricating oil to the guide pillar 3, start the solenoid valve 53 to make it in the open state. The lubricating oil inside the oil barrel 51 will slowly flow to the bottom of the partition plate 52 due to the reason of gravity. Then, close the solenoid valve 53. Immediately afterwards, press the pressure application rod 55 to apply pressure to the inside of the sleeve 54, and make the pressure enter the bottom of the partition plate 52 through the through hole 58. In this way, the lubricating oil will uniformly flow into the inside of the flow groove 591 through the four groups of oil delivery pipes 59, and flow to the outside of the guide pillar 3 through the oil outlet hole 593. The lubricating oil will slowly flow along the surface of the guide pillar 3 by gravity. At the same time, the hydraulic cylinder can be started to drive the upper die 2 to lift along the surface of the guide pillar 3, which can further make the lubricating oil on the guide pillar 3 uniform;

[0035] After the star-shaped sleeve is processed, the upper die 2 can be driven to rise by an externally connected hydraulic cylinder, that is, the connection with the lower die 1 is cancelled. Then directly start the electric push rod 61 to drive the top plate 62 to generate a top force on the star-shaped sleeve until the star-shaped sleeve is disconnected from the lower die 1, and the demoulding operation can be completed. In this way, the demoulding operation can be quickly achieved.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
