Description

Technical Field

[0001] This disclosure relates to the field of laser cutting apparatus technology, and more particularly to a laser precision cutting apparatus for core-pulling structures of complex injection molds. Background Technology

[0002] Core pulling in injection molds is a crucial step in injection mold design. It refers to the process of removing a core (or slider, side core puller) from the product during injection molding using a specific mechanical structure or hydraulic system. There are various methods for core pulling in injection molds, including angled guide post core pulling, angled slider core pulling, hydraulic core pulling, and pneumatic core pulling. Angled guide post core pulling utilizes the angled surface between the angled guide post and the slider to achieve core extraction and repositioning during mold opening and closing. Angled slider core pulling moves the core by sliding the slider on an angled surface. Hydraulic and pneumatic core pulling utilize the power of hydraulic and pneumatic systems, respectively, to drive the extraction and repositioning of the core. These two methods are typically suitable for large or complex mold structures.

[0003] In a core-pulling structure, the slider is typically pushed horizontally into the slot between the upper and lower molds when they are combined. The slider and the slot are usually designed with beveled surfaces. Therefore, when processing the slider, a cutting device is required. However, because the slider itself has both straight and beveled surfaces, precise measurement is needed to ensure cutting accuracy, which leads to low efficiency. Summary of the Invention

[0015] Optionally, a ninth electric push rod is fixed to the bottom of the clamping plates on both sides of the upper mold base and the top of the clamping plates on both sides of the lower mold base, and a limit plate is fixed to the extended end of the ninth electric push rod, and the limit plate slides in contact with the metal plate.

[0016] The technical solution provided in this disclosure may include the following beneficial effects:

[0017] 1. This invention uses two sets of bidirectional screws to drive the upper and lower clamping plates to move respectively. The lower mold base is clamped between the two clamping plates at the lower end, and the upper mold base is clamped between the two clamping plates at the upper end. The shaft frame is driven to move up and down by the second electric push rod, which can realize the merging and separation of the upper mold base and the lower mold base. After the two are aligned, the hollowed-out position in the middle is the position of the slider of the insert structure.

[0018] 2. In this invention, a metal plate is placed on a cutting table. A third electric push rod moves a right-angle frame to both sides of the bottom of the metal plate. A fourth electric push rod moves a contact plate to clamp the front and rear ends of the bottom of the metal plate with the right-angle frame. A fifth electric push rod moves a stop block to press against the bottom center of the metal plate, maintaining the stability of the metal plate during the cutting process. After the metal plate is cut on both sides by the position of the crossbar, the rotating shaft is rotated by the motor. The right-angle frame and the contact plate are sent out along the rotating groove on both sides of the cut metal plate, leaving only the middle area on the cutting table. The cutting debris is collected by the hollow groove on the cutting table.

[0019] 3. This invention uses the vertical movement of the clamping plates on both sides of the upper mold base and the synchronous movement of the slide frame driven by the ninth electric push rod to keep the crossbar pressed on the top of the metal plate. The telescopic plate maintains the connection with the slide plate. The seventh electric push rod drives the right-angle frame to move along the crossbar, adjusting the distance between the first and second slide frames to ensure that the distance between the two laser cutting devices and both sides of the metal plate is the same, allowing adjustment for the thickness of the metal plate. The connecting plate maintains the connection between the two slide plates. The motor drives the translation screw to rotate, and the screw block moves along the slide rail with the threaded engagement of the translation screw. The telescopic plate simultaneously drives the two slide plates to move along the inside of the first and second slide frames. When the clamping plates on both sides of the upper mold base are adjusted for the size of the upper mold base, the position of the crossbar is also adjusted synchronously, thereby determining the initial cutting position of the metal plate. The sixth electric push rod drives the laser cutting device to move vertically, allowing vertical cutting at the position of the crossbar. In the subsequent cutting process, the translation screw and the sixth electric push rod are still used to move the laser cutting device horizontally and vertically to precisely cut the metal plate.

[0020] 4. This invention uses four limiting plates for adjustment, ensuring that the upper two sets of limiting plates are flush with the top of the slider inside the slot, and the lower two sets of limiting plates are flush with the bottom of the slider. After being cut by a laser cutting device, the remaining metal plate is at the same height as the slider. The long plate is inserted into the slots of the upper and lower mold bases by the eighth electric push rod. Then, the fixed plate and the moving plate are moved by the built-in electric push rod, and the position of the fixed plate is adjusted. The moving plate is moved by the thirteenth electric push rod to contact the innermost end of the slot. At the same time, the fixed plate and the moving plate are pushed by the fourteenth electric push rod to contact the top block with the top of the slot, and the top block of the fixed plate corresponds to the top of the inclined surface of the slot. The tenth electric push rod... The rod drives the support plate and inner plate to move upwards, and the support plate contacts the slot entrance end of the upper mold base. The eleventh electric push rod drives the inner plate to move, aligning the inner plate with the bottom of the slot slope. The position of the slope is determined by the top block and the inner plate. The twelfth electric push rod built into the support plate, inner plate and top block drives the positioning block to move towards the metal plate side. After the laser cutting device descends with the sixth electric push rod, the limit block on the back extends through the bidirectional electric push rod and stops after contacting the positioning block. The remaining metal plate can be cut to a style and size that matches the slot, including straight and sloped surfaces. After positioning by the slot, the accuracy of the laser cutting can be guaranteed.

[0040] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0041] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8As shown in the present disclosure, an embodiment of the laser precision cutting device for core-pulling structures of complex injection molds is proposed, comprising: a base 1, with vertical frames 11 fixed on both sides of the top of the base 1, a cutting table 3 fixed at the front end of the vertical frames 11, and a metal plate 31 placed on the cutting table 3, a cutting assembly 4 provided at the top of the vertical frames 11 corresponding to the upper end of the cutting table 3, a clamping assembly 2 provided at the rear end of the vertical frames 11, an upper mold base 5 being clamped inside the clamping assembly 2, and a lower mold base 51 being spliced ​​to the lower end of the upper mold base 5, a positioning assembly 6 being provided on one side of the vertical frames 11 inserted into the upper mold base 5 and the lower mold base 51; a back plate 14 provided on the top of the base 1 at the back of the upper mold base 5 and the lower mold base 51, and a first electric... The first electric push rod 15 is fixedly connected to the top and bottom of the back plate 14 at its extended end; a slider slot is provided on one side where the upper mold base 5 and the lower mold base 51 are joined; the clamping assembly 2 includes a moving groove 12, and a moving groove 12 is provided on the rear surface of the vertical frame 11. A shaft frame 21 is slidably installed inside the moving groove 12. Insert rods 24 are slidably inserted into both ends of the shaft frame 21 and the surface of the vertical frame 11 located at the bottom of the moving groove 12, and a clamping plate 25 is fixed to one end of the insert rod 24. The upper and lower clamping plates 25 between the two sets of vertical frames 11 are respectively clamped on both sides of the upper mold base 5 and the lower mold base 51; the cutting assembly 4 includes a slide 46, and a slide 46 is provided on the top of the metal plate 31. The slide 46 is located away from the clamping. A first sliding frame 45 is fixed to one side of component 2, and a second sliding frame 47 is slidably sleeved on both sides of the slide 46. A slide plate 410 is slidably installed at the same position within both the first and second sliding frames 45 and 47. A sixth electric push rod 49 is fixed to the top of the slide plate 410, and a laser cutting device 411 is fixed to the extended end of the sixth electric push rod 49 through the slide plate 410. The positioning component 6 includes an eighth electric push rod 61. The eighth electric push rod 61 is fixed to the vertical frame 11 at the position corresponding to the slot openings of the upper mold base 5 and the lower mold base 51. A long plate 64 is fixed to the extended end of the eighth electric push rod 61. The long plate 64 is inserted into the slot. When using the device, the upper mold base 5 and the lower mold base 51 are clamped and fixed by the clamping component 2. The components are combined, and the back plate 14 is moved by the first electric push rod 15 to press the back of the upper mold base 5 and the lower mold base 51, keeping them in contact with the end of the clamping plate 25 near the cutting table 3. The metal plate 31 is placed on the cutting table 3 and clamped and fixed. The cutting component 4 cuts the distance between the two sides of the upper mold base 5 and the lower mold base 51. The positioning component 6 positions the slots of the upper mold base 5 and the lower mold base 51. The cutting component 4 cuts the metal plate 31 into a shape that matches the slot, improving cutting accuracy and efficiency. The laser cutting device 411 in this solution is based on the same principle as the laser cutting equipment used in the manufacture of intelligent welding systems, intelligent heat treatment production lines, automatic and semi-automatic electric arc and plasma arc welding machines, and other metal cutting and welding equipment.

[0042] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the clamping assembly 2 further includes: a bidirectional screw 22 and a second electric push rod 23. The shaft frame 21 and the vertical frame 11 are both rotatably mounted with bidirectional screws 22 parallel to the outer side of the insertion rod 24. The clamping plates 25 at both ends of the upper mold base 5 and the lower mold base 51 are respectively threaded onto the surface of the bidirectional screw 22 in the horizontal direction. The base 1 is located at the bottom of the shaft frame 21 and has two sets of second electric push rods 23 fixedly attached. The extended ends of the second electric push rods 23 are fixedly connected to the shaft frame 21. The shaft frame 21 and the vertical frame 11 are fixedly mounted with motors at positions corresponding to one end of the bidirectional screws 22. The bidirectional screws 22 are fixedly connected to the output end of the motors. A return spring 26 is sleeved on the outer side of the insertion rod 24. One end of the return spring 26 is fixedly connected to the insertion rod 24, and the other end of the return spring 26 is fixedly connected to the shaft frame 21 and the vertical frame 11 respectively.

[0043] Understandably, by using two sets of bidirectional screws 22 to drive the upper and lower clamping plates 25 to move respectively, the lower mold base 51 is clamped between the two clamping plates 25 at the lower end, and the upper mold base 5 is clamped between the two clamping plates 25 at the upper end. By using the second electric push rod 23 to drive the shaft frame 21 to move up and down, the upper mold base 5 and the lower mold base 51 can be merged and separated. After the two are aligned, the hollowed-out position in the middle is the position of the slider of the insert structure.

[0044] like Figure 6 and Figure 7 As shown, in some embodiments, the front ends of the vertical frame 11 are provided with rotating grooves 13 on both sides. A rotating shaft 32 is rotatably installed inside the rotating grooves 13. A third electric push rod 33 is fixed to the bottom of the rotating shaft 32, and a right-angle frame 34 is fixed to the extended end of the third electric push rod 33. A fourth electric push rod 35 is fixed to the side of the right-angle frame 34. A contact plate 36 is fixed to the extended end of the fourth electric push rod 35 through the right-angle frame 34. The bottom sides of the metal plate 31 are in contact with the right-angle frame 34 and the contact plate 36. A motor for driving the rotating shaft 32 is installed on the top of the vertical frame 11 corresponding to the rotating shaft 32. A stop block 37 is slidably installed on the top of the middle of the cutting table 3. A fifth electric push rod 38 is fixed to the outer side of the cutting table 3, and the extended end of the fifth electric push rod 38 is fixedly connected to the bottom of the stop block 37. A hollow groove is provided on the top of the cutting table 3.

[0045] Understandably, the metal plate 31 is placed on the cutting table 3. The third electric push rod 33 drives the right-angle frame 34 to move to both sides of the bottom of the metal plate 31. The fourth electric push rod 35 drives the contact plate 36 to move, which, together with the right-angle frame 34, clamps the front and rear ends of the bottom of the metal plate 31. The fifth electric push rod 38 drives the abutment block 37 to press and contact the bottom middle of the metal plate 31, maintaining the stability of the metal plate 31 during the cutting process. After the metal plate 31 is cut on both sides by the position of the crossbar 28, the rotating shaft 32 is rotated by the motor. The right-angle frame 34 and the contact plate 36 send the cut metal plate 31 out along the rotating groove 13 on both sides, leaving only the middle area on the cutting table 3. The cutting debris is collected by the hollow groove on the cutting table 3.

[0046] like Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, the cutting assembly 4 further includes: a slide rail 41, a translation screw 42, a screw block 43, and a telescopic plate 44. The slide rail 41 is fixed on the top of the vertical frame 11 at the cutting table 3. The translation screw 42 is rotatably installed inside the slide rail 41. The screw block 43 is threaded onto the surface of the translation screw 42. The telescopic plate 44 is fixed to the bottom of the screw block 43, and the extended end of the telescopic plate 44 is fixedly connected to the slide plate 410. A connecting plate 48 is fixed to the top of the slide plate 410 at the bottom of the telescopic plate 44, and the top of the slide plate 410 in the second slide frame 47 is slidably sleeved on the connecting plate 48. Lifting electric push rods 414 are fixed to the top of the vertical frame 11 on both sides corresponding to the slide 46, and the extended ends of the lifting electric push rods 414 are fixed to the slide 46. The upper mold base 5 has insert plates 27 slidably inserted into the clamping plates 25 on both sides, and a crossbar 28 is fixed to the top of the insert plates 27. One end of the crossbar 28 at the bottom of the slide frame 46 is slidably sleeved on the slide frame 46. The second slide frame 47 has a right-angle frame 413 fixed to its side, and the bottom of the right-angle frame 413 is slidably sleeved on the crossbar 28. A seventh electric push rod 412 is fixed to the bottom of the right-angle frame 413 at the bottom of the right-angle frame 413, and the extended end of the seventh electric push rod 412 is fixedly connected to the right-angle frame 413. A ninth electric push rod 62 is fixed to the bottom of the clamping plates 25 on both sides of the upper mold base 5 and the top of the clamping plates 25 on both sides of the lower mold base 51. A limit plate 63 is fixed to the extended end of the ninth electric push rod 62, and the limit plate 63 is in slidable contact with the metal plate 31.

[0047] It should be noted that by moving the clamping plates 25 on both sides of the upper mold base 5 up and down, and by driving the slide 46 to move synchronously with the ninth electric push rod 62, the crossbar 28 can be kept pressed against the top of the metal plate 31, and the telescopic plate 44 maintains the connection with the slide plate 410. The seventh electric push rod 412 drives the right-angle frame 413 to move along the crossbar 28, adjusting the distance between the first slide frame 45 and the second slide frame 47 to ensure that the distance between the two laser cutting devices 411 and both sides of the metal plate 31 is the same, which can be adjusted according to the thickness of the metal plate 31. The connecting plate 48 maintains the connection between the two slide plates 410, and the motor drives the translation screw 42 to rotate, and the screw block 43 and the... The translation screw 42 moves along the slide rail 41 in threaded engagement, and the telescopic plate 44 simultaneously drives the two slide plates 410 to move along the inside of the first slide frame 45 and the second slide frame 47. When the clamping plates 25 on both sides of the upper mold base 5 are adjusted for the size of the upper mold base 5, the position of the crossbar 28 will also be adjusted synchronously, thereby determining the initial cutting position of the metal plate 31. The laser cutting device 411 is driven to move vertically through the sixth electric push rod 49, and vertical cutting can be performed at the position of the crossbar 28. In the subsequent cutting process, the laser cutting device 411 is still moved horizontally and vertically through the translation screw 42 and the sixth electric push rod 49 to precisely cut the metal plate 31.

[0048] like Figure 9 , Figure 10 and Figure 11As shown, in some embodiments, the positioning component 6 further includes: a built-in electric push rod 610, a fixed plate 611, a movable plate 612, and a thirteenth electric push rod 613. The end of the long plate 64 away from the eighth electric push rod 61 is fixed with the built-in electric push rod 610, and the extended end of the built-in electric push rod 610 is fixed with the fixed plate 611. A movable plate 612 is provided on the outer side of the fixed plate 611, and the thirteenth electric push rod 613 is fixed on both sides of the fixed plate 611. The extended end of the thirteenth electric push rod 613 is fixedly connected to the movable plate 612. A top block 614 is provided on the top of the fixed plate 611 and the movable plate 612. A fourteenth electric push rod 615 is fixed inside the fixed plate 611 and the movable plate 612, and the extended end of the fourteenth electric push rod 615 is fixedly connected to the top block 614. The long plate 64 is close to... The top of one end of the eighth electric push rod 61 is fixed with a tenth electric push rod 65, and the extended end of the tenth electric push rod 65 is fixed with a support plate 66. The side of the support plate 66 facing the fixed plate 611 is provided with an inner plate 616. The sides of the support plate 66 are fixed with an eleventh electric push rod 67, and the extended end of the eleventh electric push rod 67 is fixedly connected to the inner plate 616. The support plate 66, the inner plate 616 and the top block 614 are all fixed with a twelfth electric push rod 68 on the side facing the metal plate 31. The extended end of the twelfth electric push rod 68 is fixed with a positioning block 69. The end of the laser cutting device 411 away from the cutting head is equipped with two limiting blocks 415 through bidirectional electric push rods. The top block 614 on the top of the inner plate 616 and the fixed plate 611 are in contact with the lowest and highest points of the slot slopes of the upper mold base 5 and the lower mold base 51, respectively.

[0049] It should be noted that the metal plate 31 is positioned on both sides by the crossbar 28. After being cut by the laser cutting device 411 on both sides of the metal plate 31, the remaining length of the metal plate 31 is the same as the length of both sides of the upper mold base 5 and the lower mold base 51. Then, it is adjusted by the four limiting plates 63 so that the two sets of upper limiting plates 63 are flush with the top of the slider in the slot, and the two sets of lower limiting plates 63 are flush with the bottom of the slider. After being cut by the laser cutting device 411, the remaining metal plate 31 is the same height as the slider. The long plate 64 is inserted into the slot of the upper mold base 5 and the lower mold base 51 by the eighth electric push rod 61. Then, the fixed plate 611 and the moving plate 612 are moved by the built-in electric push rod 610, and the position of the fixed plate 611 is adjusted. The moving plate 612 is moved by the thirteenth electric push rod 613 to contact the innermost end of the slot. The fixed plate 611 and the moving plate 612 are simultaneously pushed by the fourteenth electric push rod 615 to contact the top of the slot, and the two top blocks 614 respectively contact the top of the slot. Figure 11The top two ends of the plate 611 are shown, and the top block 614 on the top of the fixed plate 611 corresponds to the top of the inclined surface of the slot. The tenth electric push rod 65 drives the support plate 66 and the inner plate 616 to move upward. The support plate 66 contacts the slot entrance end of the upper mold base 5. The eleventh electric push rod 67 drives the inner plate 616 to move, so that the inner plate 616 corresponds to the bottom of the inclined surface of the slot. The position of the inclined surface is determined by the top block 614 and the inner plate 616. The twelfth electric push rod 68 built into the support plate 66, the inner plate 616 and the top block 614 drives the positioning block 69 to move towards the metal plate 31. After the laser cutting device 411 descends with the sixth electric push rod 49, the limiting block 415 on the back extends through the bidirectional electric push rod and stops after contacting the positioning block 69. The remaining metal plate 31 can be cut to a style and size that matches the slot, including straight and inclined surfaces. After positioning by the slot, the accuracy of the laser cutting can be guaranteed.

[0050] Working principle:

[0051] When using the device, two sets of bidirectional screws 22 drive the upper and lower clamping plates 25 to move respectively. The lower mold base 51 is clamped between the two lower clamping plates 25, and the upper mold base 5 is clamped between the two upper clamping plates 25. The second electric push rod 23 drives the shaft frame 21 to move up and down, which can realize the merging and separation of the upper mold base 5 and the lower mold base 51. After the two are aligned, the hollowed-out position in the middle is the position of the slider of the insert structure. The first electric push rod 15 drives the back plate 14 to move, pressing the back of the upper mold base 5 and the lower mold base 51, keeping it in contact with the end of the clamping plate 25 near the cutting table 3, and placing the metal plate 31 on the cutting table 3. The third electric push rod 33 drives the right angle frame 34 to move to both sides of the bottom of the metal plate 31. The fourth electric push rod 35 drives the contact plate 36 to move, which, together with the right-angle frame 34, clamps the front and rear ends of the bottom of the metal plate 31. The fifth electric push rod 38 drives the abutment block 37 to press against the bottom middle of the metal plate 31, maintaining the stability of the metal plate 31 during the cutting process. After the metal plate 31 is cut on both sides by the position of the crossbar 28, the rotating shaft 32 is rotated by the motor. The right-angle frame 34 and the contact plate 36 send the cut metal plate 31 out along the rotating groove 13 on both sides, leaving only the middle area on the cutting table 3. The cutting debris is collected by the hollow groove on the cutting table 3. The crossbar 28 is kept pressing against the top of the metal plate 31 by the up and down movement of the clamping plates 25 on both sides of the upper mold base 5 and the synchronous movement of the slide 46 driven by the ninth electric push rod 62. The upper mold base 5 is connected to the slide plate 410 via the telescopic plate 44. The right-angle frame 413 moves along the crossbar 28 via the seventh electric push rod 412, adjusting the distance between the first slide frame 45 and the second slide frame 47 to ensure that the distance between the two laser cutting devices 411 and both sides of the metal plate 31 is the same, allowing adjustment for the thickness of the metal plate 31. The two slide plates 410 are connected via the connecting plate 48. The translation screw 42 is driven to rotate by the motor, and the screw block 43 moves along the slide rail 41 with the threaded engagement of the translation screw 42. The telescopic plate 44 simultaneously drives the two slide plates 410 to move along the inside of the first slide frame 45 and the second slide frame 47. When the clamping plates 25 on both sides of the upper mold base 5 are adjusted to the size of the upper mold base 5, the position of the crossbar 28 is also adjusted synchronously. The process begins by determining the initial cutting position of the metal plate 31. The sixth electric push rod 49 drives the laser cutting device 411 vertically, allowing for vertical cutting at the position of the crossbar 28. During subsequent cutting, the translation screw 42 and the sixth electric push rod 49 continue to move the laser cutting device 411 horizontally and vertically for precise cutting of the metal plate 31. Then, four limiting plates 63 are adjusted so that the upper two sets of limiting plates 63 are flush with the top of the slider in the slot, and the lower two sets of limiting plates 63 are flush with the bottom of the slider. After cutting by the laser cutting device 411, the remaining metal plate 31 is at the same height as the slider. Finally, the eighth electric push rod 61 inserts the long plate 64 into the slots of the upper mold base 5 and the lower mold base 51.Subsequently, the built-in electric push rod 610 moves the fixed plate 611 and the movable plate 612, and adjusts the position of the fixed plate 611. The thirteenth electric push rod 613 moves the movable plate 612 to contact the innermost end of the slot. Simultaneously, the fixed plate 611 and the movable plate 612, through the fourteenth electric push rod 615, push the top block 614 to contact the top of the slot, and the two top blocks 614 respectively... Figure 11 The top two ends of the plate 611 are shown, and the top block 614 on the top of the fixed plate 611 corresponds to the top of the inclined surface of the slot. The tenth electric push rod 65 drives the support plate 66 and the inner plate 616 to move upward. The support plate 66 contacts the slot entrance end of the upper mold base 5. The eleventh electric push rod 67 drives the inner plate 616 to move, so that the inner plate 616 corresponds to the bottom of the inclined surface of the slot. The position of the inclined surface is determined by the top block 614 and the inner plate 616. The twelfth electric push rod 68 built into the support plate 66, the inner plate 616 and the top block 614 drives the positioning block 69 to move towards the metal plate 31. After the laser cutting device 411 descends with the sixth electric push rod 49, the limiting block 415 on the back extends through the bidirectional electric push rod and stops after contacting the positioning block 69. The remaining metal plate 31 can be cut to a style and size that matches the slot, including straight and inclined surfaces. After positioning by the slot, the accuracy of the laser cutting can be guaranteed.
