Description

Technical Field

[0001] This utility model relates to the field of edge trimming mold technology, and in particular to a side-sliding gate cutting mold. Background Technology

[0002] In the mass production process of metal die casting, the die-cast parts usually have redundant structures such as gates and flash, which need to be trimmed by trimming dies to meet the requirements of subsequent assembly accuracy and appearance quality. The current mainstream trimming process mostly adopts the "top and bottom cutting mode", that is, the edges and gates of the workpiece are directly punched by the vertical mold closing movement of the upper and lower dies.

[0003] However, this traditional process has significant limitations when dealing with irregularly shaped die-cast parts (such as bearing housings and complex shell-like parts). Taking bearing housings as an example, their structure has multiple sets of vertical interference surfaces: first, the die-casting gate is located in a non-vertical area of ​​the workpiece sidewall, and the vertical cutting path will collide with the workpiece body; second, the top edge of the outer arm is inclined or stepped, and vertical cutting can easily lead to edge chipping or deformation; third, the inner edge of the shaft hole is an integral structure with the workpiece body, and the upper and lower molds cannot penetrate deep into the shaft hole to complete precise edge cutting.

[0004] To address the aforementioned issues, existing solutions rely on manual intervention: operators manually remove the gate using tools such as angle grinders and chisels, then transfer the workpiece to a trimming die for edge finishing. This process has at least the following drawbacks: First, the accuracy of manual gate removal depends on the operator's experience, easily resulting in gate residue or damage to the workpiece, leading to a low product yield. Second, the step-by-step operation of manual pre-processing combined with mold trimming extends the processing time for each product. Third, manual operation requires multiple workers and carries the risk of mechanical injury, significantly increasing labor and safety management costs.

[0005] Based on this, those skilled in the art have proposed a side-sliding gate cutting mold, which provides a new solution to the above-mentioned technical problems. Utility Model Content

[0006] Therefore, it is necessary to provide a side-slider type gate cutting mold to address the problems raised in the background art.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] The aforementioned side-sliding gate cutting mold specifically includes an upper mold base and a lower mold base arranged opposite each other. The upper mold base and the lower mold base are slidably connected by guide pillars to ensure coaxiality when the mold is closed. An upper mold core adapted to the upper surface contour of the die casting to be cut is fixed at the bottom of the upper mold base. A lower mold core adapted to the lower surface contour of the die casting to be cut is fixed at the top of the lower mold base. An upper mold punching cutting edge is fixed at the bottom of the upper mold base and on the outer periphery of the upper mold core. The height of the upper mold punching cutting edge is lower than the height of the upper mold core. It is used to cut off the gate and flash of the die casting to be cut when the mold is closed.

[0009] An end-side slider assembly is installed on the top of the lower mold base and at both ends of the lower mold core along its length. A side-side slider assembly is installed on the top of the lower mold base and on one side of the lower mold core along its width. The end-side slider assembly and the side-side slider assembly are used to support the bottom of the gate position of the die-cast part to be cut during mold closing and punching.

[0010] Optionally, the end-side slider assembly includes end-side slider guide rails fixed to the top of the lower mold base and located at both ends of the lower mold core. An end-side slider is slidably connected to the inner side of the end-side slider guide rail. An end-side inclined guide post hole is opened on the inner side of the end-side slider, penetrating its upper and lower surfaces. The end of the end-side slider near the lower mold core fits snugly against the outer wall of the lower mold core. An end support block is fixed to the top of the end of the end-side slider near the lower mold core. End-side driving inclined guide posts are fixed at both ends of the bottom of the upper mold base. The end-side driving inclined guide posts correspond to and fit with the end-side inclined guide post holes at the same end. The end-side driving inclined guide posts can be inserted into the end-side inclined guide post holes to drive the end-side slider to move closer to or away from the lower mold core along the end-side slider guide rail, adjusting the relative position of the end support block and the bottom of the gate.

[0011] Optionally, the bottom of the end drive inclined guide post is integrally formed with a first bent portion. The two ends of the first bent portion are respectively provided with a first inclined driving surface. When the upper mold base drives the end drive inclined guide post to gradually insert into the end drive inclined guide post hole, the first inclined driving surface on the side closer to the lower mold core abuts against the inner wall of the end drive inclined guide post hole, driving the end side slider and end support block to slide towards the lower mold core until the end support block abuts against the bottom of the gate of the die casting to be cut. When the upper mold base drives the end drive inclined guide post to gradually withdraw from the inside of the end drive inclined guide post hole, the first inclined driving surface on the side away from the lower mold core abuts against the inner wall of the end drive inclined guide post hole, driving the end side slider and end support block to slide away from the lower mold core, disengaging from the die casting to be cut.

[0012] Optionally, spring mounting grooves are provided inside both sides of the end slider, and an end return spring is provided in the spring mounting groove. One end of the end return spring abuts against the inner wall of the spring mounting groove, and the other end abuts against the inner wall of the corresponding end slider guide rail.

[0013] Optionally, an oil cylinder is installed on the inner side of the end slider guide rail and at the end of the end slider away from the lower mold core, for driving the end slider to perform a pre-positioning movement. When the end driving inclined guide post is pulled out from the inner side of the corresponding end inclined guide post hole, the end return spring pushes the end slider to abut against the output end of the oil cylinder.

[0014] Optionally, the side slider assembly includes side slider guide rails fixed at both ends of one side of the lower mold core. Each of the two side slider guide rails has a side slider groove extending along its length on one side close to each other. A side slider is slidably connected inside the two side slider grooves. Side support blocks are fixed at both ends of the side slider near the lower mold core. A side return spring is provided at one end of the side slider groove near the lower mold core. Both ends of the side return spring abut against the side slider and the corresponding inner wall of the side slider groove, respectively. Side inclined guide post holes are provided on both sides of the side slider. A side driving inclined guide post, adapted to the side inclined guide post hole, is fixed at the bottom of the upper mold base. The side driving inclined guide post can be inserted into the corresponding side inclined guide post hole to drive the side slider to slide along the side slider groove.

[0015] Optionally, the bottom of the side drive inclined guide post is integrally formed with a second bent portion. The two ends of the second bent portion are respectively provided with second inclined driving surfaces. When the upper mold base drives the side drive inclined guide post to gradually insert into the side drive inclined guide post hole, the second inclined driving surface on the side closer to the lower mold core abuts against the inner wall of the side drive inclined guide post hole, driving the side slider and side support block to slide towards the lower mold core. When the upper mold base drives the side drive inclined guide post to gradually withdraw from the inside of the side drive inclined guide post hole, the second inclined driving surface on the side away from the lower mold core abuts against the inner wall of the side drive inclined guide post hole, driving the side slider and side support block to slide away from the lower mold core.

[0016] Optionally, when the side support block and the end support block are close to the lower mold core and abut against the outside of the part to be cut, the side support block and the end support block together support the bottom of the gate of the part to be cut.

[0017] Optionally, the bottom of the upper die core is fixed with a shaft hole punching edge, and the inner side of the lower die core is provided with a waste material guide channel through it in an inclined direction. The top opening of the waste material guide channel is located below the shaft hole punching edge, and the bottom opening extends out of the outer side of the lower die core to discharge the waste material generated by punching.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This invention avoids the structural interference problems of traditional top-to-bottom cutting and irregular parts by using the lateral punching support design of the end side slider assembly and the side side slider assembly. During the mold closing process, only one vertical mold closing action is needed to simultaneously complete the cutting of the end gate, side gate, top edge of the outer wall and inner edge of the shaft hole of the part to be cut. No manual pre-processing is required, the process integration is greatly improved, the production efficiency is increased, and the intensity of manual labor is reduced. Attached Figure Description

[0030] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 should fall within the protection scope of the present invention.

[0031] Please refer to Figure 1-7 The present invention provides a side-sliding gate cutting mold, comprising an upper mold base 2 and a lower mold base 3 arranged opposite to each other. The upper mold base 2 and the lower mold base 3 are slidably connected by guide pillars to ensure coaxiality of mold closing. The bottom of the upper mold base 2 is fixed with an upper mold core 4 that matches the contour of the upper surface of the die casting 1 to be cut. The top of the lower mold base 3 is fixed with a lower mold core 5 that matches the contour of the lower surface of the die casting 1 to be cut. During assembly, the lower mold core 5 is fixed to the center position of the top of the lower mold base 3 with bolts to ensure that the positioning reference of the lower mold core 5 is coaxial with the guide pillar hole of the lower mold base 3. The upper mold core 4 is fixed to the center position of the bottom of the upper mold base 2 with bolts to ensure that the contours of the upper mold core 4 and the lower mold core 5 are completely matched.

[0032] Please refer to Figure 2-4 The upper mold base 2 has an upper mold cutting edge 24 fixed at the bottom and on the outer periphery of the upper mold core 4. The height of the upper mold cutting edge 24 is lower than the height of the upper mold core 4. Its design purpose is to cut off the gate and surrounding flash of the die casting 1 to be cut off by priority to the pressing contact of the upper mold core 4 when the mold is closed.

[0033] An end side slider assembly 6 is installed on the top of the lower mold base 3 and at both ends of the lower mold core 5 along the length direction. A side side slider assembly 7 is installed on the top of the lower mold base 3 and on one side of the lower mold core 5 along the width direction. The end side slider assembly 6 and the side side slider assembly 7 are used to support the bottom of the gate position of the die casting 1 to be cut during mold closing and punching, so as to prevent damage to the workpiece during the punching process.

[0034] During the punching process, the worker places the die-cast part 1 to be cut on the lower mold core 3, so that the lower mold core 3 fits against the inner wall of the die-cast part 1 to support and position it. Then, the upper mold base 2 descends, causing the upper mold core 4 to descend. It should be noted that the upper mold base 2 is connected to an external power system, which is usually a hydraulic cylinder. The cylinder extends, causing the upper mold base 2 to descend, and the cylinder retracts, causing the upper mold base 2 to rise. This is existing technology and should be understood by those skilled in the art, so it will not be elaborated on here. The upper die punching edge 24 descends with the upper mold base 2. During the descent, it will drive the end side slider assembly 6 and the side side slider assembly 7 to support the bottom of the gate position of the die-cast part 1 to be cut. During the descent, the upper mold core 4 and the die-cast part 1... The edge die casting 1 is fitted to prevent misalignment, and the upper die cutting edge 24 cuts off the gate and flash on the edge die casting 1. When the mold is closed, the upper mold base 2 and the lower mold base 3 are slidably connected by guide pillars to ensure the coaxiality of the mold. The upper mold core 4 and the lower mold core 5 are respectively fitted to the upper and lower surfaces of the edge die casting 1 to be cut, and the workpiece is pre-positioned by using contour adaptation. Since the height of the upper die cutting edge 24 is lower than that of the upper mold core 4, the upper mold core 4 first presses the workpiece to avoid displacement during the mold closing process. Then the upper die cutting edge 24 contacts and cuts off the gate and flash. At the same time, the end side slider assembly 6 and the side side slider assembly 7 support the bottom of the gate from the side to counteract the deformation torque generated by the punching force, ensuring accurate punching position. No step-by-step operation is required, which improves production efficiency.

[0035] Please refer to Figure 5The end-side slider assembly 6 includes end-side slider guide rails 12 fixed to the top of the lower mold base 3 and located at both ends of the lower mold core 5. End-side sliders 13 are slidably connected to the inner side of the end-side slider guide rails 12. End-side sliders 13 have end-side inclined guide post holes 14 penetrating their upper and lower surfaces on their inner side. The end of the end-side slider 13 near the lower mold core 5 is fitted to the outer wall of the lower mold core 5. An end-side support block 15 is fixed to the top of the end of the end-side slider 13 near the lower mold core 5. End-side drive inclined guide posts 9 are fixed to both ends of the bottom of the upper mold base 2. The end-side drive inclined guide posts 9 correspond to and fit with the end-side inclined guide post holes 14 at the same end. The end-side drive inclined guide posts 9 can be inserted into the end-side inclined guide post holes 14 to drive the end-side sliders. The side slider 13 moves closer to or further away from the lower mold core 5 along the end slider guide rail 12, adjusting the relative position of the end support block 15 and the bottom of the gate. The end side slider assembly 6 achieves dynamic support for the bottom of the gate through the inclined guide post drive and guide rail guidance. Specifically, when the mold is closed, the upper mold base 2 drives the end drive inclined guide post 9 to insert into the end inclined guide post hole 14. Utilizing the cooperation between the hole wall and the inclined guide post, the vertical movement is converted into a horizontal force, pushing the end side slider 13 to slide along the end slider guide rail 12 towards the lower mold core 5 until the end support block 15 fits against the bottom of the gate. When the mold is opened, the end drive inclined guide post 9 and the end side slider 13 slide in the opposite direction to reset, reserving space for the next part assembly. The end side slider 13 fits snugly against the outer wall of the die casting 1 to be cut, ensuring no shaking during sliding. The end side slider 13 fits snugly against the outer wall of the die casting 1 to resist the punching lateral force and prevent the end support block 15 from shifting.

[0036] Please refer to Figure 2-5The bottom of the end drive inclined guide post 9 is integrally formed with a first bent portion. Both ends of the first bent portion are respectively provided with first inclined driving surfaces. When the upper mold base 2 drives the end drive inclined guide post 9 to gradually insert into the end inclined guide post hole 14, the first inclined driving surface near the lower mold core 5 abuts against the inner wall of the end inclined guide post hole 14, causing the end side slider 13 and the end support block 15 to slide towards the lower mold core 5 until the end support block 15 abuts against the bottom of the gate of the die-cast part 1 to be trimmed. When the upper mold base 2 drives the end drive inclined guide post 9 to gradually withdraw from the inside of the end inclined guide post hole 14, the side away from the lower mold core 5... The first inclined driving surface abuts against the inner wall of the end inclined guide post hole 14, driving the end side slider 13 and the end support block 15 to slide away from the lower mold core 5, disengaging from the die-cast part 1 to be cut. Both sides of the end side slider 13 are provided with spring mounting grooves, and the spring mounting grooves are provided with end return springs 16. One end of the end return spring 16 abuts against the inner wall of the spring mounting groove, and the other end abuts against the inner wall of the corresponding end slider guide rail 12. Specifically, the first bent part of the end driving inclined guide post 9 realizes the bidirectional controllable movement of the end side slider 13 through the first inclined driving surfaces on both sides. When the mold is closed, the upper mold base 2 moves downward and the first inclined driving surface on the side closer to the lower mold core 5 abuts against the inner wall of the end inclined guide post hole 14, converting the vertical pressure into a horizontal thrust, driving the end side slider 13 and the end support block 15 to move toward the workpiece until the end support block 15 presses against the bottom of the gate; when the mold is opened, the upper mold base 2 moves upward and the first inclined driving surface on the side away from the lower mold core 5 abuts against the inner wall of the end inclined guide post hole 14, and the end return spring 16 pushes the end side slider 13 to slide in the opposite direction and disengage from the workpiece.

[0037] Please refer to Figure 5A hydraulic cylinder 17 is installed on the inner side of the end slider guide rail 12 and at the end of the end slider 13 away from the lower mold core 5. It is used to drive the end slider 13 to perform a pre-positioning movement. When the end drive inclined guide post 9 is pulled out from the inner side of the corresponding end inclined guide post hole 14, the end return spring 16 pushes the end slider 13 to abut against the output end of the hydraulic cylinder 17. Specifically, the hydraulic cylinder 17 and the end drive inclined guide post 9 form a dual power system to drive the end slider 13 to move. Before the part is installed, the end-side slider 13 is moved close to the lower mold core 5 by the hydraulic cylinder 17. The output end of the hydraulic cylinder 17 extends and pushes the end-side slider 13 to the preset initial position (at this time, the end inclined guide post hole 14 is located below the end drive inclined guide post 9) to achieve the pre-positioning. When the mold is closed, the end drive inclined guide post 9 is gradually inserted into the end inclined guide post hole 14 to drive the end-side slider 13 to move towards the workpiece. At this time, the end-side slider 13 disengages from the output end of the hydraulic cylinder 17, and the hydraulic cylinder 17 is activated to retract and reset its output end. When the mold is opened, the end drive inclined guide post 9 is gradually pulled out of the end inclined guide post hole 14 and drives the end-side slider 13 away from the workpiece. When the end drive inclined guide post 9 disengages from the end inclined guide post hole 14, the end reset spring 16 pushes the end-side slider 13 to reset, so that it abuts against the output end of the hydraulic cylinder 17 again. The rigid support of the hydraulic cylinder ensures that the position of the end-side slider 13 is stable.

[0038] Please refer to Figure 4-7 The side slider assembly 7 includes side slider guide rails 18 fixed at both ends of one side of the lower mold core 5. Each of the two side slider guide rails 18 has a side slider groove 23 extending along its length on one side closest to each other. Side sliders 19 are slidably connected inside the two side slider grooves 23. Side support blocks 20 are fixed at both ends of the side slider 19 near the lower mold core 5. A side return spring 21 is provided at one end of the side slider groove 23 near the lower mold core 5. The two ends of the side return spring 21 abut against the side slider 19 and the corresponding inner wall of the side slider groove 23, respectively. Side inclined guide post holes 22 are provided on both sides of the side slider 19. The upper mold base... 2. A side drive inclined guide post 10 is fixed at the bottom, which is adapted to the side inclined guide post hole 22. The side drive inclined guide post 10 can be inserted into the corresponding side inclined guide post hole 22, driving the side slider 19 to slide along the side slider groove 23. When the mold is closed, the upper mold base 2 drives the side drive inclined guide post 10 to insert into the side inclined guide post hole 22. By utilizing the cooperation between the hole wall and the inclined guide post, the vertical movement is converted into a horizontal force, pushing the side slider 19 to slide along the side slider guide rail 18 towards the lower mold core 5 until the side support block 20 fits against the bottom of the gate. When the mold is opened, the side drive inclined guide post 10 and the side slider 19 slide in the opposite direction to reset, reserving space for the next part assembly. The side slider 19 fits well with the outer wall of the die casting 1 to be cut, ensuring no shaking during the sliding process. The side support block 20 fits against the outer wall of the die casting 1 to be cut, resisting the punching lateral force and preventing the side support block 20 from shifting.

[0039] Please refer to Figure 4-7 The bottom of the side drive inclined guide post 10 is integrally formed with a second bent part. The two ends of the second bent part are respectively provided with second inclined driving surfaces. When the upper mold base 2 drives the side drive inclined guide post 10 to gradually insert into the side inclined guide post hole 22, the second inclined driving surface on the side closer to the lower mold core 5 abuts against the inner wall of the side inclined guide post hole 22, driving the side slider 19 and the side support block 20 to slide towards the lower mold core 5. When the upper mold base 2 drives the side drive inclined guide post 10 to gradually withdraw from the inside of the side inclined guide post hole 22, the second inclined driving surface on the side away from the lower mold core 5 abuts against the inner wall of the side inclined guide post hole 22, driving the side slider 19 and the side support block 20 to slide away from the lower mold core 5. Specifically, the second bent part of the side drive inclined guide post 10 realizes the bidirectional controllable movement of the side slider 19 through the second inclined driving surfaces on both sides. When the mold is closed, the upper mold base 2 moves downward and the second inclined driving surface on the side near the lower mold core 5 abuts against the inner wall of the side inclined guide post hole 22, converting the vertical pressure into a horizontal thrust. The side slider 19 and the side support block 20 move toward the workpiece until the side support block 20 presses against the bottom of the gate. When the mold is opened, the upper mold base 2 moves upward and the second inclined driving surface on the side away from the lower mold core 5 abuts against the inner wall of the side inclined guide post hole 22. The side return spring 21 pushes the side support block 20 to slide in the opposite direction and disengage from the workpiece.

[0040] When the side support block 20 and the end support block 15 approach the lower mold core 5 and abut against the outside of the part to be cut, the side support block 20 and the end support block 15 together support the bottom of the gate of the part to be cut. The side support block 20 and the end support block 15 form a closed support structure through a surrounding support method. When the mold is closed, the two approach the die-cast part 1 to be cut from one side in the width direction and both ends in the length direction, and finally support the bottom of the gate, so as to evenly distribute the shearing force generated by the punching edge to the support block, and avoid excessive local stress that may cause gate deformation or workpiece damage.

[0041] Please refer to Figure 6 The upper mold core 4 has a shaft hole punching edge 8 fixed at its bottom. The lower mold core 5 has a waste material guide channel 11 installed through it along an inclined direction on its inner side. The top opening of the waste material guide channel 11 is located below the shaft hole punching edge 8, and the bottom opening extends out of the lower mold core 5 to discharge the waste material generated by punching. The shaft hole punching edge 8 and the waste material guide channel 11 cooperate to realize the punching and automatic waste discharge of the redundant shaft hole structure. When the mold is closed, the upper mold core 4 drives the shaft hole punching edge 8 to insert into the shaft hole of the die-cast part 1 to be cut, and cuts off the redundant edge of the inner wall. The annular waste material generated by punching falls into the top opening of the waste material guide channel 11 under the action of gravity, slides down the inclined channel of the waste material guide channel 11, and is finally discharged from the bottom opening to the collection device outside the mold.
