Description

Technical Field

[0001] The invention relates to the technical field of hydraulic press parts processing, in particular to precise positioning equipment used for casting processing of hydraulic press parts. Background Art

[0002] The hydraulic press is composed of several important parts. The first is the body, which provides a stable support structure for the entire equipment to ensure that it will not shake or deform during operation. The hydraulic pump is one of the key components, responsible for pumping and pressurizing the hydraulic oil from the tank to provide a power source for the hydraulic press. The hydraulic cylinder is the actuator, which drives the piston to move through the pressure of the hydraulic oil to achieve operations such as pressing and stretching the workpiece.

[0003] Die casting is a common method of manufacturing parts of hydraulic presses. When processing parts through die casting, it is necessary to fill the mold with hot molten metal liquid.

[0014] Beneficial Effects

[0015] The present invention provides a precise positioning device for casting and processing of hydraulic press parts. Compared with the prior art, it has the following beneficial effects:

[0016] 1. This is a precise positioning device for casting processing of hydraulic press parts. After cooling and forming, restart the first hydraulic rod to drive the top plate to move up, and move the upper die below up and separate from the lower die. After separation, the cooled and formed workpiece will be located above the lower die. Then, start the second hydraulic rod to drive the support plate to move up, and the support plate moves up to drive the lower die to move up. By moving the lower die up, the lower die can be moved out from the bottom shell. After the lower die is moved out, it is convenient for workers to take out the workpiece from the lower die, thereby achieving the purpose of convenient demoulding.

[0017] 2. The precise positioning equipment for casting processing of hydraulic press parts can release the fixation of the mounting block by pulling the lower die to one side with force. The lower die can squeeze the block back into the slide groove under the action of the pulling force, and the mounting block can be taken out from the inside of the mounting groove, so that the lower die can be easily taken out. When facing parts with complex shapes that are not convenient for demolding, the lower die can be removed and the parts can be demolded on the outside. When demolding, a new lower die can be reinstalled for continued die-casting, thereby further ensuring convenient demolding and achieving the purpose of high processing efficiency.

[0018] 3. This precise positioning equipment for casting processing of hydraulic press parts can clean the residual impurities and dust inside the lower mold by blowing high-pressure gas into the lower mold, reduce the impurities inside the workpiece after die-casting, and clean the lower mold while the upper mold descends. There is no need to clean the mold separately, which greatly reduces the steps required for operation and improves production efficiency.

[0019] 4. This precise positioning equipment is used for casting and processing of hydraulic press parts. The connecting rod moves up synchronously, and the movement of the connecting rod drives the pull rod to move up, and the movement of the pull rod drives the piston column to move up. The rapid upward movement of the piston column can absorb air from the air pipe. The air absorbed at this time is the hot air that has not been completely dissipated during cooling after die-casting. By absorbing the hot air discharged instantly when the mold is opened, it can effectively prevent the hot air from diffusing outward due to expansion when the mold is opened, thereby protecting the workers near the mold.

[0020] 5. The air on the left side is squeezed by the piston plate moving to the left. After the air on the left side is squeezed, the air will enter the alarm air whistle through the cylinder. When the heat of the absorbed air is high, the piston plate is squeezed a large distance. At this time, the rapid movement of the air can blow the alarm air whistle. When the heat of the absorbed air is low, the squeezing distance is small, and the air cannot blow the alarm air whistle. This realizes the judgment of the heat of the air at this time while absorbing the hot air, thereby preventing workers from being scalded when demolding the workpiece.

The inside of the clamping groove 36 is arc-shaped, and the outer end of the clamping block 35 is arc-shaped, and the outer end of the clamping block 35 is completely fitted into the inside of the clamping groove 36.

[0042] In this embodiment, when the lower mold 31 is installed above the support plate 32, the installation block 33 is inserted into the installation slot 34 to achieve the installation of the lower mold 31. When installing the lower mold 31, the installation block 33 is inserted into the installation slot 34 from the side. When inserting, the external clamping block 35 contacts the inner wall of the installation slot 34 and moves to the inside of the slide slot 37 under the action of the extrusion force. At this time, the first spring 38 is contracted. When the clamping block 35 moves to align with the clamping slot 36, it moves to the inside of the clamping slot 36 under the action of the expansion force of the first spring 38. The clamping block 35 is inserted into the inside of the clamping slot 36, so that the installation block 33 is fixed in the installation slot 34, and the clamping block 35 is inserted into the inside of the clamping slot 36. The design of the block 35 and the slot 36 is such that, after the installation of the lower mold 31 is completed, the lower mold 31 can be pulled forcefully to one side, and the lower mold 31 can squeeze the block 35 back into the slide slot 37 under the action of the pulling force, so that the fixation of the mounting block 33 can be released, and the mounting block 33 can be taken out from the mounting slot 34, so that the lower mold 31 can be easily taken out, so that when faced with parts with complex shapes that are not convenient for demolding, the lower mold 31 can be removed and the parts can be demolded from the outside, and when demolding, a new lower mold 31 can be reinstalled for continued die-casting, thereby further ensuring convenient demolding and achieving the purpose of high processing efficiency.

[0043] Reference Figures 1 to 12 In one aspect of the present embodiment, a support frame 44 is fixedly mounted on the bottom of the air pump 41, and the support frame 44 is fixedly mounted on the top of the base 1. A groove 46 is provided inside the movable plate 23, and the groove 46 is located above the air pipe 45. The detection component 5 includes an auxiliary shell 51, and the auxiliary shell 51 is fixedly mounted on the outer side of the bottom of the air pump 41.

[0044] A second spring 54 is fixedly installed inside the left side of the auxiliary shell 51, a piston plate 55 is fixedly installed on the right side of the second spring 54, the piston plate 55 is slidably connected inside the auxiliary shell 51, a cylinder 52 is fixedly installed on the top of the auxiliary shell 51, the connection point between the cylinder 52 and the auxiliary shell 51 is located on the left side of the piston plate 55, and an alarm whistle 53 is fixedly installed on the top of the cylinder 52.

[0045] In this embodiment, when the movable plate 23 moves downward to close the lower mold 31 and the upper mold 27, the movable plate 23 moves downward to drive the connecting rod 43 to move downward, and the connecting rod 43 moves downward to drive the lower pull rod 42 to move downward, and the pull rod 42 moves downward to drive the lower piston column 47 to move downward.

After the air is compressed, the compressed air enters the air pipe 45 through the bottom of the air pump 41, and the compressed gas is discharged from the outlet of the air pipe 45 at a high speed. After being discharged, the high-speed gas will blow to the inside of the bottom shell 21. The lower die 31 is cleaned of impurities and dust remaining inside the lower die 31 by blowing high-pressure gas into the lower die 31, thereby reducing impurities inside the workpiece after die-casting. The lower die 31 is cleaned while the upper die 27 is descending, without the need to clean the die separately, thereby greatly reducing the number of steps required for operation and improving production efficiency.

The air absorbed at this time is the hot air that has not been completely dissipated during cooling after die casting. By absorbing the hot air discharged at the moment of opening the mold when the mold is opened, it can effectively prevent the hot air from diffusing outward due to expansion when the mold is opened, thereby protecting the workers near the mold; and when the heat is absorbed into the inside of the air pump 41, the heat conductive sheet 57 can quickly absorb the heat in the air and transfer it to the inside of the auxiliary shell 51 through the heat conductive sheet 57. After being transferred to the inside of the auxiliary shell 51, the air on the right side of the piston plate 55 inside the auxiliary shell 51 can be heated. After the right air is heated, the piston plate 55 The piston plate 55 moves to the left under the action of the expansion of the air, thereby squeezing the air on the left through the piston plate 55 moving to the left. After the air on the left is squeezed, the air will enter the alarm air whistle 53 through the cylinder 52. When the heat of the absorbed air is high, the piston plate 55 is squeezed a large distance. At this time, the rapid movement of the air can blow the alarm air whistle 53. When the heat of the absorbed air is low, the squeezing distance is small, and the air cannot blow the alarm air whistle 53. This achieves the purpose of judging the heat of the air at this time while absorbing the hot air, thereby preventing workers from being scalded when demolding the workpiece.

[0046] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0047] Working principle: When die-casting a workpiece, first start the first hydraulic rod 25 to drive the moving plate 23 to move downward. The moving plate 23 can drive the upper mold 27 below to move downward. The upper mold 27 moves downward and moves to the top of the lower mold 31 below, and the upper mold 27 and the lower mold 31 are buckled. After buckling, the hot molten metal liquid is passed through the feed port set above the moving plate 23 to the space between the upper mold 27 and the lower mold 31. After passing, the hot molten metal liquid is completely filled between the upper mold 27 and the lower mold 31. After filling, the workpiece inside is cooled. After cooling and molding, the first hydraulic rod 25 is restarted to drive the top plate 24 to move upward, and the upper mold 27 below is moved upward and separated from the lower mold 31. , the workpiece that has been cooled and formed after separation will be located above the lower die 31, and then the support plate 32 will be driven upward by starting the second hydraulic rod 26, and the upward movement of the support plate 32 will drive the lower die 31 to move upward, and the lower die 31 can be moved out of the bottom shell 21 by moving the lower die 31 upward, and the lower die 31 can be moved out to facilitate workers to take out the workpiece from the lower die 31, thereby achieving the purpose of convenient demoulding; and when the upper die 27 and the lower die 31 are closed, the upper die 27 is driven to move by the moving plate 23, and when the moving plate 23 moves, the support rods 22 at the four outer corners are used to guide the moving plate 23, so that the moving plate 23 can move along a fixed route when moving, thereby ensuring the accuracy of the movement. When the lower mold 31 is installed above the support plate 32, the installation block 33 is inserted into the installation groove 34 to achieve the installation of the lower mold 31. When installing the lower mold 31, the installation block 33 is inserted into the installation groove 34 from the side. When inserted, the external clamping block 35 contacts the inner wall of the installation groove 34 and moves to the inside of the slide groove 37 under the action of the extrusion force. At this time, the first spring 38 is contracted. When the clamping block 35 moves to align with the clamping groove 36, it moves to the inside of the clamping groove 36 under the action of the expansion force of the first spring 38. The clamping block 35 is inserted into the inside of the clamping groove 36, so that the installation block 33 is fixed in the installation groove 34, and the clamping block 35 The design of the card slot 36 ensures that, after the installation of the lower mold 31 is completed, the lower mold 31 can be pulled hard to one side, and the lower mold 31 can squeeze the card block 35 back into the slide groove 37 under the action of the pulling force, so that the fixation of the mounting block 33 can be released, and the mounting block 33 can be taken out from the mounting groove 34, so that the lower mold 31 can be easily taken out, so that when faced with parts with complex shapes that are not convenient to demold, the lower mold 31 can be removed and the parts can be demolded from the outside, and when demolding, a new lower mold 31 can be reinstalled for continued die-casting, thereby further ensuring convenient demolding and achieving the purpose of high processing efficiency.When the movable plate 23 moves downward to close the lower mold 31 and the upper mold 27, the movable plate 23 moves downward to drive the connecting rod 43 to move downward, and the connecting rod 43 moves downward to drive the lower pull rod 42 to move downward, and the pull rod 42 moves downward to drive the lower piston column 47 to move downward. The downward piston column 47 compresses the air inside the air pump 41. After the air is compressed, the compressed air enters the air pipe 45 through the bottom of the air pump 41. The compressed gas is discharged from the outlet of the air pipe 45 at a high speed. After being discharged, the high-speed gas will be blown into the lower mold 31 inside the bottom shell 21. The lower mold 31 is cleaned by blowing high-pressure gas into the lower mold 31, thereby reducing the impurities in the workpiece after die-casting. The lower mold 31 is cleaned while the upper mold 27 is descending, without the need to clean the mold separately, which greatly reduces the number of steps required and improves production efficiency. When the moving plate 23 moves upward after the die-casting of the workpiece is completed, the connecting rod 43 moves upward synchronously, the connecting rod 43 moves upward to drive the pull rod 42 to move upward, and the pull rod 42 moves upward to drive the piston rod 47 to move upward. The rapid upward movement of the piston rod 47 can absorb air from the air pipe 45. The air absorbed at this time is the hot air that has not been completely dissipated during cooling after die casting. By absorbing the hot air discharged at the moment of opening the mold when the mold is opened, it is possible to effectively prevent the hot air from diffusing outward due to expansion when the mold is opened, thereby protecting the workers near the mold; and when the heat is absorbed into the inside of the air pump 41, the heat conductive sheet 57 can quickly absorb the heat in the air and transfer it to the inside of the auxiliary shell 51 through the heat conductive sheet 57. After being transferred to the inside of the auxiliary shell 51, the air on the right side of the piston plate 55 inside the auxiliary shell 51 can be heated. After the right side air is heated, the piston plate 55 The air expands and moves to the left, thereby squeezing the air on the left through the piston plate 55 moving to the left. After the air on the left is squeezed, the air passes through the cylinder 52 and enters the alarm air whistle 53. When the heat of the absorbed air is high, the piston plate 55 is squeezed a large distance. At this time, the rapid movement of the air can blow the alarm air whistle 53. When the heat of the absorbed air is low, the squeezing distance is small, and the air cannot blow the alarm air whistle 53. This achieves the purpose of judging the heat of the air at this time while absorbing the hot air, thereby preventing workers from being scalded when demolding the workpiece.
