Description

Technical Field

[0001] This invention relates to the field of ejector pin holes, specifically to a mold ejector pin hole positioning and machining device and its machining method. Background Technology

[0002] After the product cools and solidifies in the mold, it needs to be reliably ejected from the mold using ejector pins that pass through the ejector pin holes. The mechanism that accomplishes this function is called an ejection system. Ejector pin ejection is one type of ejection system. Ejector pins can also be called ejector pins, push rods, insert pins, center pins, support pins, etc. Positioning the mold is a crucial step when machining the ejector pin holes.

[0003] In the prior art, such as the Chinese patent CN108526941A "A Mold Processing Positioning Device", a base and a column are included. The top of the clamping block is bolted to the bottom of the column. A positioning sleeve is sleeved on the outside of the column. The guide cylinder is threadedly connected to the screw. A push plate is vertically installed on the end of the screw near the base. The side of the push plate away from the screw contacts the plate. The plate is placed on the upper part of the base. A support screw is vertically installed on one side of the plate on the upper part of the base. The support screw passes through the clamping block.

[0004] However, in the existing technology, during the process of fixing the mold, one side of the mold needs to be fitted against the inside of a positioning block, and then another positioning block needs to be slid to fit against the other side of the mold.

[0014] Preferably, the lower end of the sliding rod passes through the disk and engages with the inside of the slot, and one end of the rotating rod two is rotatably connected to the inside of the sliding block three.

[0015] A processing method for a mold ejector pin hole positioning processing device includes the following steps:

[0016] Step 1: Place the mold on the carrier structure and clamp the mold with the two positioning blocks;

[0017] (1) Turn on the drive device. The output end of the drive device drives the rotating rod to rotate clockwise, which in turn drives the gear to rotate clockwise.

[0018] (2) Gear 1 drives two racks 1 to slide on the two connecting plates respectively, so that they move closer to each other, thereby driving the two connecting blocks 1 to move closer to each other, thereby driving the two positioning blocks 1 to move closer to each other, and clamping the mold located above the load structure 7.

[0019] Step 2: Lower the material structure so that ejector pin holes can also be machined in the middle area of ​​the mold;

[0020] (1) The drive device can continue to drive the rotating rod to rotate clockwise, so that the rotating rod and the gear rotate relative to each other;

[0021] (2) The disc continues to rotate together with the rotating rod one. The inner wall of the slot squeezes the lower end of the sliding rod, causing it to move upward into the interior of the disc, which in turn drives the rotating rod two to rotate clockwise, causing the positioning block two to move downward inside the disc.

[0022] (3) When the second positioning block moves to the inside of the two racks, the inclined side of the rack will squeeze the second positioning block, causing the second positioning block to move upward and squeeze the spring, so that it continues to move with the disc to the outside of the two racks.

[0023] (4) After the second positioning block contacts the outer side of the first rack, the two second positioning blocks will be blocked on one side of the two first racks respectively, so that the rotating rod and the disk will also rotate relative to each other.

[0024] (5) At this time, the arc grooves of the two racks rotate to the outside of the two arc blocks respectively. The gear continues to rotate clockwise, which will drive the front rack to move to the left and the rear rack to move to the right, thereby driving the two connecting blocks to move away from each other, and thus driving the two sliding plates to move away from each other.

[0025] (6) The two sliding plates will cause one end of the two rotating blocks to move away from each other, causing them to rotate and drive the load block to move downward, thus facilitating the drilling of the pin hole;

[0026] Step 3: Start the vertical deep hole drill body to process the mold.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] 1. In this invention, by setting the rack, the drive device can be directly activated when fixing the mold to complete the fixing of the mold. During the process, the mold is supported by the load block, which improves the stability of fixing the mold, saves a lot of time, and improves the positioning and processing efficiency.

[0029] 2. In this invention, through the cooperation between the carrying structure and the transmission structure, the driving device can drive the carrying structure to move downward after the mold is clamped, which facilitates the positioning and processing of the mold.

[0030] 3. In this invention, by setting up a connecting structure, the clamping of the mold and the retraction of the carrier structure can be completed in sequence using only one driving device. The connection between the two movements is smoother, which further facilitates the positioning and processing of the mold. Attached Figure Description

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0041] Reference Figure 1-8The following describes a mold ejector pin hole positioning machining device and its machining method: A vertical deep hole drill body 1 and a driving device 3 are included. A support frame 2 is provided at one end of the vertical deep hole drill body 1. A rotating rod 4 is fixedly installed at the output end of the driving device 3. A transmission structure 5 and a transmission structure 6 are provided on the outer side of the rotating rod 4. A carrying structure 7 is provided at the upper end of the transmission structure 6. Two connecting structures 8 are provided between the transmission structure 5 and the transmission structure 6. The transmission structure 5 includes a gear 51, with two racks 52 meshing on the outer side of the gear 51. One end of each rack is fixedly installed... There is a connecting block 53, and a positioning block 54 is fixedly installed on the upper end of the connecting block 53. The carrying structure 7 is located between the two positioning blocks 54. The upper end of the gear 51 has two slots 55. The inside of the gear 51 matches the outside of the rotating rod 4. A disc 56 is provided on the outside of the rotating rod 4. The lower end of the disc 56 contacts the upper end of the gear 51. The transmission structure 6 includes a gear 61. Two racks 62 mesh on the outside of the gear 61. The outer sides of the two racks 62 are slidably connected to a locking block 64. The upper end of the rack 62 has an arc-shaped groove 63. One end of the rack 62 is provided with a connecting... Connecting block 2 65, with an arc-shaped block 66 fixedly installed at its lower end. The outer side of the arc-shaped block 66 is slidably connected to the inside of the arc-shaped groove 63. The vertical deep hole drill body 1 includes a support column 11. A sliding block 12 is drivenly connected to one side of the support column 11. A sliding block 2 13 is drivenly connected to the lower end of the sliding block 12. A drill bit 14 is fixedly installed at the lower end of the sliding block 2 13. The carrying structure 7 includes a carrying block 71. Two rotating blocks 72 are rotatably connected inside the carrying block 71. A sliding plate 73 is rotatably connected to one end of each of the two rotating blocks 72. The lower ends of the two sliding plates 73 are respectively connected to the upper ends of the two connecting blocks 2 65. The gear 61 is fixed to the inside of the rotating rod 4. The support frame 2 includes a base plate 21. Two support plates 22 are fixedly installed on the upper end of the base plate 21. A fixing plate 23 is fixedly installed between the two support plates 22. Four connecting plates 24 are fixedly installed between the two support plates 22. The upper ends of two connecting plates 24 are slidably connected to the lower ends of two racks 52, and the upper ends of the other two connecting plates 24 are slidably connected to the lower ends of two racks 62. The upper ends of two connecting blocks 53 are slidably connected to the inside of the fixing plate 23. The lower end of the drive device 3 is fixed to the upper end of the base plate 21.

[0042] In this embodiment, when fixing the mold, the drive device 3 is turned on, so that the output end of the drive device 3 drives the rotating rod 4 to rotate clockwise, which in turn drives the gear 51 to rotate clockwise. The gear 51 drives the two racks 52 to slide on the two connecting plates 24 respectively, so that they move closer to each other, which in turn drives the two connecting blocks 53 to move closer to each other, thereby driving the two positioning blocks 54 to move closer to each other and clamp the mold located above the carrying structure 7. Since there is a certain friction between the inside of the gear 51 and the outside of the rotating rod 4, after the two positioning blocks 54 clamp the mold, the drive device 3 can continue to drive the rotating rod 4 to rotate clockwise, so that the rotating rod 4 and the gear 51 rotate relative to each other. Example 2

[0043] Figure 4-8 As shown, the connecting structure 8 includes a connecting rod 81, a sliding rod 82 slidably connected inside the connecting rod 81, a connecting block 83 fixedly installed on the outside of the sliding rod 82, a rotating rod 84 rotatably connected to one end of the connecting block 83, two fixing blocks 85 fixedly installed on the upper end of the disc 56, a rotating rod 86 rotatably connected between the two fixing blocks 85, the inside of the rotating rod 84 rotatably connected to the outside of the rotating rod 86, a positioning block 88 slidably connected inside the disc 56, a sliding block 87 slidably connected inside the positioning block 88, a groove 67 opened at the lower end of the rack 62, the inside of the groove 67 slidably connected to the outside of the connecting rod 81, a spring 89 fixedly installed at the lower end of the sliding block 87, the lower end of the spring 89 fixed to the inside of the positioning block 88, the lower end of the sliding rod 82 passes through the disc 56 and engages with the inside of the slot 55, and one end of the rotating rod 84 rotatably connects to the inside of the sliding block 87.

[0044] In this embodiment, when the rotating rod 4 drives the gear 51 to rotate clockwise, the rotating rod 4 also drives the gear 61, the two racks 62, and the locking block 64 to rotate clockwise. Furthermore, the rotating rod 4 also drives the disk 56 and the two connecting structures 8 on the disk 56 to rotate clockwise. The two connecting structures 8 are located at one end inside the two sliding grooves 67, preventing relative movement between the gear 61 and the rack 62. After relative rotation occurs between the rotating rod 4 and the gear 51, the friction between the disk 56 and the rotating rod 4 is relatively large, causing... As the disc 56 continues to move along with the rotating rod 4, the inner wall of the slot 55 presses against the lower end of the sliding rod 82, causing it to move upwards into the disc 56. This, in turn, drives the rotating rod 84 to rotate clockwise, causing the positioning block 88 to move downwards inside the disc 56. Due to the different dimensions of different molds, the rotation angle of the gear 51 will also be different, which may cause the connecting block 65 to not be parallel to the rack 62. When the lower end of the positioning block 88 moves to the bottom of the disc 56, the positioning block 88 will rotate along with the disc 56. When 88 moves to the inner side of the two racks 52, the inclined design of the inner corners of rack 52 causes the inclined edge of rack 52 to press against positioning block 88, causing positioning block 88 to move upward and press spring 89. It then continues to move with disk 56 to the outer side of the two racks 52 until it contacts the outer side of rack 52. Afterward, the two positioning blocks 88 are blocked on one side of the two racks 52, causing relative rotation between rotating rod 4 and disk 56. At this time, the arc-shaped grooves 63 of the two racks 62 rotate to the two arcs 62 respectively. On the outside of block 66, the two connecting structures 8 will stop rotating along with the disk 56, so that the two racks 62 can no longer rotate around gear 61. Gear 61 continues to rotate clockwise, which will drive the front rack 62 to move to the left and the rear rack 62 to move to the right. This will cause the two connecting blocks 65 to move away from each other, which will cause the two sliding plates 73 to move away from each other. The two sliding plates 73 will cause one end of the two rotating blocks 72 to move away from each other, causing them to rotate and drive the load block 71 to move downward, thus facilitating the drilling of the pin hole. Example 3

[0045] A processing method for a mold ejector pin hole positioning processing device includes the following steps:

[0046] S1. Place the mold on the carrier structure 7 and clamp the mold with the two positioning blocks 54.

[0047] S11. Turn on the drive device 3. The output end of the drive device 3 drives the rotating rod 4 to rotate clockwise, which in turn drives the gear 51 to rotate clockwise.

[0048] S12, Gear 51 drives two racks 52 to slide on the two connecting plates 24 respectively, so that they move closer to each other, thereby driving the two connecting blocks 53 to move closer to each other, which in turn drives the two positioning blocks 54 to move closer to each other and clamp the mold located above the load structure 7.

[0049] S2, Lowering the material structure 7, allows for the machining of ejector pin holes in the middle area of ​​the mold;

[0050] S21. The drive device 3 can continue to drive the rotating rod 4 to rotate clockwise, so that the rotating rod 4 and the gear 51 rotate relative to each other.

[0051] S22, the disc 56 continues to rotate together with the rotating rod 4. The inner wall of the slot 55 squeezes the lower end of the sliding rod 82, causing it to move upward into the interior of the disc 56, which in turn drives the rotating rod 84 to rotate clockwise, causing the positioning block 88 to move downward inside the disc 56.

[0052] S23. When the positioning block 2 88 moves to the inside of the two racks 1 52, the inclined side of the rack 1 52 will squeeze the positioning block 2 88, causing the positioning block 2 88 to move upward and squeeze the spring 89, so that it continues to move with the disc 56 to the outside of the two racks 1 52.

[0053] S24. After the positioning block 2 88 contacts the outer side of the rack 1 52, the two positioning blocks 2 88 will be blocked on one side of the rack 1 52 respectively, so that the rotating rod 1 4 and the disk 56 will also rotate relative to each other.

[0054] S25. At this time, the arc grooves 63 of the two racks 62 rotate to the outside of the two arc blocks 66 respectively. The gear 61 continues to rotate clockwise, which will drive the front rack 62 to move to the left and the rear rack 62 to move to the right, thereby driving the two connecting blocks 65 to move away from each other, and thus driving the two sliding plates 73 to move away from each other.

[0055] S26. The two sliding plates 73 will drive one end of the two rotating blocks 72 away from each other, causing them to rotate and drive the load block 71 to move downward, thus facilitating the drilling of the pin hole.

[0056] S3. Start the vertical deep hole drill body 1 to process the mold.

[0057] The operating method and working principle of this device are as follows: When fixing the mold, the drive device 3 is turned on, causing the output end of the drive device 3 to drive the rotating rod 4 to rotate clockwise, which in turn drives the gear 51 to rotate clockwise. The gear 51 then drives the two racks 52 to slide on the two connecting plates 24, bringing them closer together. This, in turn, causes the two connecting blocks 53 to move closer together, which in turn causes the two positioning blocks 54 to move closer together and clamp the mold located above the carrying structure 7. Due to the friction between the inside of the gear 51 and the outside of the rotating rod 4, after the two positioning blocks 54 clamp the mold, the drive device 3 can continue to drive the rotating rod 4 to rotate clockwise, causing relative rotation between the rotating rod 4 and the gear 51. When the rotating rod 4 drives the gear 51 to rotate clockwise, the rotating rod 4 also drives the gear 61, the two racks 62, and the locking block 64 to rotate clockwise. Furthermore, the rotating rod 4 also drives the disc 56 and the two connecting structures 8 on the disc 56 to rotate clockwise. The two connecting structures 8 are located at one end inside the two sliding grooves 67, preventing relative movement between the gear 61 and the rack 62. After the rotating rod 4 and the gear 51 rotate relative to each other, due to the high friction between the disc 56 and the rotating rod 4, as the disc 56 continues to move with the rotating rod 4, the inner wall of the locking groove 55 presses against the lower end of the sliding rod 82, causing it to move upwards into the disc 56, thereby driving the rotating rod 84. Rotating clockwise causes positioning block 2 88 to move downwards inside disk 56. Due to the different dimensions of different molds, the rotation angle of gear 1 51 will also be different, which may cause connecting block 2 65 to not be parallel to rack 2 62. The lower end of positioning block 2 88 moves to the bottom of disk 56, and positioning block 2 88 will rotate with disk 56. When positioning block 2 88 moves to the inside of the two racks 1 52, the inclined design of the inner corners of rack 1 52 will cause the inclined edge of rack 1 52 to squeeze positioning block 2 88, causing positioning block 2 88 to move upwards and squeeze spring 89, thus continuing to move with disk 56 to the outside of the two racks 1 52 until it contacts the outside of rack 1 52. After that, the two positioning blocks 2 88 will... The two racks 52 are blocked on one side, causing the rotating rod 4 and the disk 56 to rotate relative to each other. At this time, the arc grooves 63 of the two racks 62 rotate to the outside of the two arc blocks 66, and the two connecting structures 8 stop rotating along with the disk 56. This prevents the two racks 62 from continuing to rotate around the gear 61. The gear 61 continues to rotate clockwise, which will drive the front rack 62 to move to the left and the rear rack 62 to move to the right. This will cause the two connecting blocks 65 to move away from each other, which will in turn cause the two sliding plates 73 to move away from each other. The two sliding plates 73 will cause one end of the two rotating blocks 72 to move away from each other, causing them to rotate and drive the load block 71 to move downward, thus facilitating the drilling of the pin hole.This design achieves the goal of using only one motor to sequentially complete the clamping of the mold and the retraction of the carrying structure 7, reducing the number of motors required and facilitating mold positioning and processing.
