Description
Technical Field
[0001] The utility model relates to the technical field of die casting moulds, in particular to a structure for positioning a sliding block on a die casting mould. Background Art
[0002] A die-casting mold is a mold used to produce die-casting parts. If the die-casting mold is an integrated structure, after the die-casting parts are die-casted, the die-casting parts with complex structures or shapes usually cannot be demolded by opening the mold. Therefore, existing die-casting molds usually include a movable mold and a fixed mold. Sliders are respectively arranged at both ends of the die-casting mold composed of the movable mold and the fixed mold. The slider and the movable mold and the fixed mold form a cavity for the die-casting part to be die-cast. The structure of the slider is designed according to the shape structure of the die-casting part, and the die-casting part can be demolded by moving the slider.
[0003] In actual production, in order to reduce the hidden danger of pores inside the die casting and ensure the mechanical properties of the die casting, the actual pressure of the die casting is usually adjusted to be slightly greater than the design pressure. This behavior will cause the slider to have a long stroke. In addition, aluminum liquid may enter the gap between the slider and the mold, causing the slider to be stuck and misaligned. In addition, during the mass production of die castings, the slider itself will be worn due to the long-term reciprocating motion of the slider. The above reasons will make it impossible for the slider to reach the designed position, resulting in changes in the shape, structure and size of the die casting, making it impossible to assemble and use the die casting products normally.
[0004] The utility model aims to solve the problem that the slider of the existing die-casting mold often cannot reach the designed position, resulting in changes in the shape, structure and size of the die-casting. Utility Model Content
[0005] In order to solve the above problems, the utility model provides a slider positioning structure, including a slide rail 1, a slider 2, a telescopic power device, a connecting member 4 and a positioning member 5. The slide rail 1 extends in the front-to-back direction, and the slider 2 is slidably arranged on the slide rail 1. The connecting member 4 includes a connecting tube 41 and a connecting rod 43. The connecting tube 41 is arranged on the slider 2 and extends in the front-to-back direction. The front end of the connecting tube 41 is fixedly connected to the rear side of the slider 2, and a limiting ring 42 is arranged at the rear end. The connecting rod 43 extends in the front-to-back direction, and the front end can be slidably inserted into the connecting tube 41. The end is provided with a connecting block 44, and the rear end is fixedly connected to the telescopic power device.
[0006] The positioning member 5 includes a positioning tube 51, a positioning spring 52 and a positioning rod 53. The slide rail 1 is provided with a positioning groove 14 matching the positioning rod 53. The positioning tube 51 is fixedly arranged at the rear side of the slider 2, one end of which is fixedly connected to the connecting tube 41, and the other end extends to the side of the slider 2. The positioning rod 53 is slidably arranged in the positioning tube 51, one end of which passes through the side wall of the connecting tube 41 and extends to the middle of the connecting tube 41, and a positioning plate 54 is arranged at the end, and the other end passes through the end of the positioning tube 51 and extends to the side close to the slider 2. The positioning spring 52 is arranged in the positioning tube 51, sleeved on the positioning rod 53, one end of which is close to the connecting tube 41 and is fixedly connected to the positioning rod 53, and the other end is fixedly connected to the positioning tube 51. The positioning plate 54 is arranged vertically, and the positioning plate 54 gradually tilts toward one side of the connecting tube 41 from front to back.
[0007] When in use, the utility model is installed on one side of the fixed mold 62 and the sliding membrane of the die-casting mold 6. Before the die-casting operation is performed, the telescopic power device is extended to push the connecting rod 43 to move forward in the connecting tube 41, so that the connecting block 44 slides and abuts against the positioning plate 54 on the positioning rod 53. After the positioning plate 54 is pushed by the connecting block 44, the slider 2 is pushed forward, and at the same time, the positioning rod 53 is pushed to overcome the elastic force of the positioning spring 52 and move toward the outside of the slider 2 until the end of the positioning rod 53 abuts against the slide rail 1. When the slider 2 moves to the designed position, the positioning rod 53 is aligned with the positioning groove 14 on the slide rail 1. The positioning rod 53 is inserted into the positioning groove 14 under the thrust of the connecting block 44 to position the slider 2. The cavity 63 for the die-casting to be formed by the slider 2, the movable mold 61 and the fixed mold 62 can be used for the die-casting operation.
[0008] After the die-casting operation is completed, the telescopic power device contracts, pulling the connecting rod 43 to move backward in the connecting tube 41, and the connecting block 44 moves backward, the thrust given to the positioning plate 54 disappears, and the positioning rod 53 moves toward the inside of the slider 2 under the elastic force of the positioning spring 52, so that the end of the positioning rod 53 is pulled out from the positioning groove 14. When the connecting block 44 retreats to contact the limit ring 42 on the connecting tube 41, a backward pulling force is applied to the connecting tube 41, pulling the slide to slide backward along the slide rail 1 to the initial position, and the die-casting can be taken out.
[0009] The utility model sets a connecting member 4 and a positioning member 5 on the slider 2. When the telescopic power device controls the connecting rod 43 to push the slider 2 forward, the positioning rod 53 can be pushed to slide outward through the cooperation of the connecting block 44 and the positioning plate 54. When the slider 2 slides to the designed position, the positioning rod 53 is pushed and inserted into the positioning groove 14, so as to position the slider 2. When the telescopic power device controls the connecting rod 43 to pull the slider 2 to move backward, the thrust of the connecting block 44 to the positioning plate 54 disappears, and the positioning rod 53 moves to the inside of the slider 2 under the elastic force of the positioning spring 52. The end of the positioning rod 53 is pulled out of the positioning groove 14, so that the connecting block 44 pulls the slider 2 to slide backward along the slide rail 1 to the initial position, which is convenient for the die casting to be taken out. The utility model can solve the problem that the slider 2 of the die casting mold 6 cannot reach the designed position, resulting in changes in the shape, structure and size of the die casting.

DETAILED DESCRIPTION
[0029] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.
[0030] like Figure 1 and Figure 2 As shown, the slider positioning structure includes a slide rail 1, a slider 2, a telescopic power device, a connecting member 4 and a positioning member 5.
[0031] The slide rail 1 extends in the front-to-back direction, and includes a left side plate 11 and a right side plate 12. The left side plate 11 and the right side plate 12 are vertically arranged, parallel to each other, and maintain a spacing, forming a channel 13 in the middle for the slider 2 to move. The inner side walls of the left side plate 11 and the right side plate 12 are respectively provided with limiting slide grooves 15 extending in the front-to-back direction.
[0032] The slider 2 is slidably disposed in the channel 13 between the left plate 11 and the right plate 12. The left and right sides of the slider 2 are respectively provided with limit blocks 21 matching the limit slots 15. The two limit blocks 21 are respectively slidably disposed in the limit slots 15 on the left plate 11 and the right plate 12. A base 22 is disposed at the bottom of the slider 2.
[0033] The left and right sides of the slider 2 are respectively provided with limit blocks 21 that match the limit slide groove 15, wherein the matching means that the shape and size of the cross section of the limit block 21 and the limit slide groove 15 are the same, so that the limit block 21 can be slidably inserted into the limit slide groove 15, and the limit block 21 is in contact with the inner side wall of the limit slide groove 15. Through the cooperation between the limit block 21 and the limit slide groove 15, the slider 2 is limited so that the slider 2 can only slide in the front and rear directions along the slide rail 1.
[0034] The slide rail 1 includes a left side plate 11 and a right side plate 12, and a channel 13 is formed between the left side plate 11 and the right side plate 12. The slider 2 is slidably arranged in the channel 13, and the slider 2 can be limited to prevent the slider 2 from deviating in the left and right directions. The left side plate 11 and the right side plate 12 are provided with a limiting slide groove 15, and the left and right sides of the slider 2 are provided with a limiting block 21. The limiting block 21 is slidably arranged in the limiting slide groove 15, and the slider 2 can be limited to prevent the slider 2 from deviating in the up and down directions, so that the limiting block 21 can only slide in the front and back directions.
[0035] The telescopic power device is a telescopic cylinder 3 extending in the front-rear direction. The cylinder body 31 of the telescopic cylinder 3 is used to be fixed on the die-casting mold 6 , and the piston rod 32 of the telescopic cylinder 3 is fixedly connected to the rear end of the connecting rod 43 .
[0036] like Figure 1 and Figure 3 As shown, the connecting member 4 includes a connecting tube 41 and a connecting rod 43. The connecting tube 41 is arranged on the slider 2 and extends along the front-to-back direction. The front end of the connecting tube 41 is fixedly connected to the rear side of the slider 2, and a limiting ring 42 is arranged at the rear end.
[0037] The connecting rod 43 extends in the front-to-back direction, the front end of which can be slidably inserted into the connecting tube 41, the end of which is provided with a connecting block 44, and the rear end of which is fixedly connected to the telescopic power device.
[0038] like Figure 3 and Figure 4 As shown, the positioning member 5 includes a positioning tube 51, a positioning spring 52 and a positioning rod 53. The positioning tube 51 is fixedly arranged on the rear side of the slider 2, one end of which is fixedly connected to the connecting tube 41, and the other end extends to the side of the slider 2. A guide block 56 is arranged on the inner wall of the positioning tube 51.
[0039] The positioning rod 53 is slidably disposed in the positioning tube 51, one end of which passes through the side wall of the connecting tube 41 and extends to the middle of the connecting tube 41, and a positioning plate 54 is disposed at the end thereof, and the other end of which passes through the end of the positioning tube 51 and extends to the side near the slider 2, and a guide slot 55 is disposed on the positioning rod 53, which extends along the axis and matches the guide block 56. The guide block 56 is slidably disposed in the guide slot 55.
[0040] The positioning rod 53 is provided with a guide groove 55 extending axially and matching with the guide block 56, wherein the matching means that the shape and size of the cross section of the guide groove 55 and the guide block 56 are the same, so that the guide block 56 can be slidably set in the guide groove 55, and the guide block 56 is in contact with the inner wall of the guide groove 55. Through the cooperation between the guide block 56 and the guide groove 55, the slider 2 is limited so that the slider 2 can only slide in the front and rear directions.
[0041] The positioning spring 52 is disposed in the positioning tube 51 and sleeved on the positioning rod 53 . One end of the positioning spring 52 close to the connecting tube 41 is fixedly connected to the positioning rod 53 , and the other end of the positioning spring 52 is fixedly connected to the positioning tube 51 .
[0042] The positioning plate 54 is vertically arranged, and the positioning plate 54 gradually inclines toward one side of the connecting tube 41 from the front side to the rear side.
[0043] The connecting block 44 is spherical, and the diameter of the connecting block 44 is larger than the inner ring diameter of the limiting ring 42 and smaller than the inner diameter of the connecting tube 41 .
[0044] The connecting block 44 is set to be spherical. When the telescopic cylinder 3 pushes the telescopic rod to move forward, the connecting block 44 abuts against the positioning plate 54 on the positioning rod 53. When the positioning rod 53 is pushed to move along the positioning tube 51 toward the outside of the slider 2, the connecting block 44 and the positioning plate 54 slide relative to each other, which can reduce the friction between the connecting block 44 and the positioning plate 54.
[0045] A guide block 56 is provided on the inner wall of the positioning tube 51, and a guide groove 55 is provided on the positioning rod 53. The guide block 56 is slidably provided in the guide groove 55. Through the cooperation of the guide block 56 and the guide groove, the positioning rod 53 can be limited so that the positioning rod 53 can only slide axially along the positioning tube 51 and cannot rotate relative to the positioning tube 51.
[0046] like Figure 5 and Figure 6 As shown, two positioning members 5 are provided, and the two positioning members 5 are relatively arranged on the left and right sides of the connecting tube 41. Positions corresponding to the positioning rods 53 on the inner side walls of the left plate 11 and the right plate 12 are both provided with positioning grooves 14 matching the positioning rods 53.
[0047] The positions of the positioning rods 53 on the inner side walls of the left plate 11 and the right plate 12 correspond, where correspondence refers to the positions on the left plate 11 and the right plate 12 to which the positioning rods 53 point when the slider 2 slides to the designed position.
[0048] Positions corresponding to the positioning rod 53 are provided with positioning grooves 14 matching the positioning rod 53 on the inner walls of the left plate 11 and the right plate 12, wherein the matching means that the diameter of the positioning groove 14 is equal to or slightly larger than the diameter of the positioning rod 53, so that the positioning rod 53 can be slidably inserted into the positioning groove 14, and the positioning rod 53 fits with the inner wall of the positioning groove 14 to position the slider 2.
[0049] The working process of the connecting member 4 and the positioning member 5 is as follows: the piston rod 32 of the telescopic cylinder 3 extends to push the connecting rod 43 forward, and pushes the connecting block 44 forward to slide and abut against the positioning plate 54. After the positioning plate 54 receives the thrust of the connecting block 44, part of the thrust is decomposed into the forward power of the slider 2. The slider 2 moves forward slowly along the slide rail 1, and part of the thrust is decomposed into the power for the positioning rod 53 to move toward the outside of the slider 2, so that the positioning rod 53 overcomes the elastic force of the positioning spring 52 and moves toward the outside of the slider 2 until the end of the positioning rod 53 abuts against the slide rail 1. When the slider 2 slides to the designed position, the positioning rod 53 is aligned with the positioning groove 14 on the slide rail 1, and the positioning rod 53 is pushed and inserted into the positioning groove 14.
[0050] The piston rod 32 of the telescopic cylinder 3 contracts, pulling the connecting rod 43 backward, driving the connecting block 44 backward, and the thrust applied to the positioning plate 54 disappears. The positioning rod 53 moves toward the inside of the slider 2 under the elastic force of the positioning spring 52, so that the end of the positioning rod 53 is pulled out of the positioning groove 14. When the connecting block 44 retreats to contact the limit ring 42 on the connecting tube 41, a backward pulling force is applied to the connecting tube 41, pulling the slide to slide backward along the slide rail 1 to the initial position.
[0051] Two positioning members 5 are provided, and the positioning rods 53 of the two positioning members 5 are respectively inserted into the positioning grooves 14 of the left plate 11 and the right plate 12 to position the slider 2 from both sides, so that the slider 2 can be subjected to balanced forces and aligned.
[0052] like Figure 7 As shown, when in use, the utility model is installed on the side of the fixed mold 62 and the sliding membrane of the die-casting mold 6. Before the die-casting operation, the piston rod 32 of the telescopic cylinder 3 is extended to push the connecting rod 43 to move forward in the connecting tube 41, so that the connecting block 44 slides and abuts against the positioning plate 54 on the positioning rod 53. After the positioning plate 54 is pushed by the connecting block 44, it pushes the slider 2 to move forward, and at the same time pushes the positioning rod 53 to overcome the elastic force of the positioning spring 52 to move toward the outside of the slider 2 until the end of the positioning rod 53 abuts against the slide rail 1. When the slider 2 moves to the designed position, the positioning rod 53 is aligned with the positioning groove 14 on the slide rail 1. The positioning rod 53 is inserted into the positioning groove 14 under the thrust of the slider 2 to position the slider 2. The cavity 63 for the die-casting to be formed by the slider 2, the movable mold 61 and the fixed mold 62, the die-casting operation can be carried out.
[0053] After the die-casting operation is completed, the piston rod 32 of the telescopic cylinder 3 contracts, pulling the connecting rod 43 to move backward in the connecting tube 41, and the connecting block 44 moves backward. The thrust applied to the positioning plate 54 disappears, and the positioning rod 53 moves toward the inside of the slider 2 under the elastic force of the positioning spring 52, so that the end of the positioning rod 53 is pulled out of the positioning groove 14. When the connecting block 44 retreats to contact the limit ring 42 on the connecting tube 41, a backward pulling force is applied to the connecting tube 41, pulling the slide to slide backward along the slide rail 1 to the initial position, and the die-casting can be taken out.
[0054] The utility model sets a connecting member 4 and a positioning member 5 on the slider 2. When the telescopic power device controls the connecting rod 43 to push the slider 2 forward, the positioning rod 53 can be pushed to slide outward through the cooperation of the connecting block 44 and the positioning plate 54. When the slider 2 slides to the designed position, the positioning rod 53 is pushed and inserted into the positioning groove 14, so as to position the slider 2. When the telescopic power device controls the connecting rod 43 to pull the slider 2 to move backward, the thrust of the connecting block 44 to the positioning plate 54 disappears, and the positioning rod 53 moves to the inside of the slider 2 under the elastic force of the positioning spring 52. The end of the positioning rod 53 is pulled out of the positioning groove 14, so that the connecting block 44 pulls the slider 2 to slide backward along the slide rail 1 to the initial position, which is convenient for the die casting to be taken out. The utility model can solve the problem that the slider 2 of the die casting mold 6 cannot reach the designed position, resulting in changes in the shape, structure and size of the die casting.
[0055] The slide rail 1 includes a left side plate 11 and a right side plate 12, and a channel 13 is formed between the left side plate 11 and the right side plate 12. The slider 2 is slidably arranged in the channel 13. The left side plate 11 and the right side plate 12 cooperate to limit the slider 2 to prevent the slider 2 from deviating in the left and right directions. A limiting groove 15 is arranged on the left side plate 11 and the right side plate 12, and a limiting block 21 is arranged on the left and right sides of the slider 2, so that the limiting block 21 is slidably arranged in the limiting groove 15. The slider 2 can be limited by the cooperation of the limiting groove 15 and the limiting block 21 to prevent the slider 2 from deviating in the up and down directions, so that the limiting block 21 can only slide in the front and back directions.
[0056] The connecting block 44 is spherical, so that when the telescopic oil cylinder 3 pushes the telescopic rod forward, the connecting block 44 can slide and abut against the positioning plate 54 on the positioning rod 53, pushing the positioning rod 53 to move toward the outside of the slider 2 along the positioning cylinder 51, thereby reducing the friction between the connecting block 44 and the positioning plate 54. A guide block 56 is provided on the inner wall of the positioning cylinder 51, and a guide slot 55 is provided on the positioning rod 53. The guide block 56 is slidably provided in the guide slot 55. Through the cooperation of the guide block 56 and the guide slot, the positioning rod 53 can be limited, so that the positioning rod 53 can only slide axially along the positioning cylinder 51, and cannot rotate relative to the positioning cylinder 51.
[0057] It should be noted that the above-mentioned embodiments illustrate rather than limit the invention and that those skilled in the art will be able to design alternative embodiments without departing from the scope of the appended claims.
