Description

Technical Field

[0001] The present invention relates to the technical field of automotive part processing, specifically a die-casting mold for the processing of automotive steering motor end covers. Background Art

[0002] As a key component of the automotive steering system, the automotive steering motor end cover plays an important role in the steering performance and safe operation of the vehicle. In recent years, with the rapid development of the automotive industry, the demand for automotive steering motor end covers has been continuously increasing. At the same time, consumers and automotive manufacturers have put forward more stringent requirements for its quality and production efficiency. Against this background, the die-casting mold technology for the processing of automotive steering motor end covers has emerged and is constantly evolving and innovating.

[0003] With the continuous growth of global automotive production and sales, in order to enhance market competitiveness, automotive manufacturers pay more attention to the quality and performance of parts while reducing production costs. As an important part of the steering motor, the automotive steering motor end cover directly affects the stability and reliability of the motor, and thus the overall steering performance of the vehicle. Traditional end cover processing technologies, such as machining and welding, are difficult to meet the increasing production demand, and have low production efficiency and high costs. Die-casting technology, with its advantages of high production efficiency, high dimensional accuracy, and good surface quality, has become an ideal choice for the large-scale production of automotive steering motor end covers, which has also greatly promoted the development of die-casting mold technology.

[0004] It should be noted in combination with the above content that the Chinese patent with the application number CN2023236284528 discloses a die-casting mold for a power steering motor housing. When ejecting, the ejector plate provided is different from the ejector post with a smaller ejecting area. The ejector plate can disperse the ejecting force, making the formed product have a larger force-bearing area and preventing it from being deformed by ejection, and then ejecting the product.

[0005] In fact, during the die-casting and demolding of the automotive steering motor end cover, according to the reasonable arrangement of the mold cavity structure, the problem of difficult demolding can be greatly avoided. Moreover, the hardness of the cast body of the steering motor end cover after cooling and forming, as well as the viscosity generated by the pressure between the inner wall of the mold cavity during forming, cause damage to the inner wall of the mold cavity during the demolding of the steering motor end cover. The traditional mold is an integral structure. Therefore, the overall repair of the internal damage of the mold is difficult, time-consuming, and affects the subsequent processing efficiency of the overall automotive steering motor end cover.

[0006] In view of the above technical defects, a solution is proposed now. Summary of the Invention

[0007] The purpose of the present invention is to provide a die-casting mold for the processing of automotive steering motor end covers to solve the problems raised.

[0008] To achieve the above object, the present invention provides the following technical solutions: A die-casting mold for machining an end cover of an automotive steering motor, including a feeding die segment. In the middle of one end of the feeding die segment, a feeding connection seat is sleeved. A number of distributing valves are arranged in a circular array on the outer periphery of the feeding connection seat. In the middle of the other end of the feeding die segment, a pouring core is nested. Inside the pouring core, a number of unloading push blocks are arranged in a circular array in the central core. On the end face of the pouring core, a pouring splicing inner die segment is arranged to cooperate and sleeve with the outer wall of the end face of the feeding die segment. The pouring splicing inner die segment includes a pouring segment one and a pouring segment two;

[0009] On one end of the feeding die segment close to the pouring splicing inner die segment, a die-casting die segment is arranged side by side. In the middle of the end of the die-casting die segment far from the feeding die segment, a pressure-bearing push plate is arranged. An exhaust outer valve is arranged on the outer wall of the pressure-bearing push plate. In the middle of the end of the die-casting die segment close to the feeding die segment, a pressing core is nested. On the end face of the pressing core, a pressing splicing inner die segment is arranged to cooperate and sleeve with the outer wall of the end face of the die-casting die segment. Travel guide rods are symmetrically sleeved at the four corners of the end faces of the feeding die segment and the die-casting die segment.

[0010] Further, a number of locking grooves are symmetrically recessed at the top and bottom of the feeding die segment. A number of cooperating side limiting grooves are symmetrically penetrated through both sides of the feeding die segment and the die-casting die segment. Sliding holes sleeved with the travel guide rods are symmetrically penetrated through the four corners of the end faces of the feeding die segment and the die-casting die segment.

[0011] Further, a fixed shaft seat is fixedly arranged at the central core of the end face of the feeding connection seat. A number of strengthening trays connected to the distributing valves one by one are arranged in a circular array on the outer periphery of the feeding connection seat. Inside the distributing valve, a molten metal conduit connecting the pouring core and the pouring splicing inner die segment is arranged.

[0012] Further, the pouring segment one and the pouring segment two have the same structure. Inside the central core of both the pouring segment one and the pouring segment two, a set of removable and detachable pouring cores are nested. A number of valve-changing connection holes are symmetrically arranged at the top of the pouring segment one and the pouring segment two. Metal collar rings are arranged in the connection areas between the pouring cores and the pouring segment one and the pouring segment two. A number of metal collar rings are sleeved and embedded into the inner wall of the feeding die segment in sequence to construct a multi-level detachable replacement module on the end face of the feeding die segment.

[0013] Further, on both sides of one end of the pouring segment one and the pouring segment two facing the die-casting die segment, limiting side frames are symmetrically arranged. A convex strip is slidably sleeved in the middle of the outer side wall of the limiting side frame. A number of exhaust valves are symmetrically arranged at the bottom of the pouring segment one and the pouring segment two.

[0014] Further, an explosion-proof shaft seat is fixedly installed in the middle of the end of the pressure-bearing push plate far from the die-casting die segment. A number of side strengthening ribs connecting the die-casting die segment are arranged in a circular array on the outer periphery of the pressure-bearing push plate. Inside the exhaust outer valve, a number of communicating air ducts extending to the pressing core are arranged.

[0015] Further, a die pressing disc is recessed in the middle of one end of the die pressing core facing the injection die flap. An inner pushing ring is arranged in the middle of one end of the die pressing disc. A plurality of groups of foot pushing blocks are arranged in a circular array along the inner wall edge of one end of the die pressing disc. The pressed and spliced inner die flap includes a first pressing flap and a second pressing flap. A micro cylinder is arranged inside the foot pushing block.

[0016] Further, the traveling guide rod is sleeved inside the sliding hole of the die casting die flap. The traveling guide rod is provided with a matching sleeve rod sleeved inside the sliding hole of the injection die flap. The matching sleeve rod is provided with a cylinder kit clamped with the inner wall of the sliding hole of the injection die flap.

[0017] Further, a die ring disc connected to the unloading push block is arranged inside the injection die core. A plurality of groups of injection holes arranged annularly around the unloading push block are arranged on the end face of the die ring disc.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The present invention can accurately and continuously fill the cavity between the injection die core and the die pressing core with metal solution evenly by adopting external injection equipment for pressure boosting and guiding, in cooperation with the design of the flow dividing valve, the metal liquid conduit and the injection holes. This not only ensures sufficient filling of each part of the end cover, but also effectively avoids product defects caused by uneven injection, greatly improving the stability of product quality.

[0020] 2. The present invention can timely guide the excess air in the cavity to the exhaust outer valve and the exhaust valve through the air vent designed on the injection die core and the die pressing core according to the end cover model, reducing the generation of defects such as air holes and air streaks, and improving the strength and sealing performance of the product. At the same time, the internally designed spiral air duct or spiral water pipe can rapidly cool and shape after the metal solution is poured, shortening the production cycle, improving the production efficiency, and helping to improve the dimensional accuracy and internal tissue performance of the product.

[0021] 3. The present invention can smoothly pull the die casting die flap away from the injection die flap by matching the traveling guide rod with the external hydraulic mechanism to prepare for unloading. The external air supply equipment and the exhaust outer valve cooperate to form negative pressure adsorption, which can prevent the end cover from accidentally falling during the initial stage of demolding and ensure safe demolding. The coordinated design of the first propulsion cylinder and the foot pushing block, as well as the second propulsion cylinder and the inner pushing ring, realizes multi-point synchronous unloading of the end cover, avoiding product deformation caused by single-point stress, ensuring the smoothness of the unloading process and the integrity of the product. The design of the adjusting cylinder and the unloading push block inside the injection die core further assists in unloading, helping to achieve damage-free unloading treatment.

[0022] 4. The present invention, through the combination of a crane equipped at the top of the die-casting equipment and the design of valve replacement connection holes, enables the rapid disassembly of damaged components, such as the second injection valve and the second pressing valve, for synchronous cleaning and maintenance when abnormal damage is found in the injection die core or the pressing die core. During the maintenance period, the first injection valve and the first pressing valve can still cooperate to continue the die-casting operation, greatly reducing the long-term shutdown for maintenance caused by die damage, ensuring the continuity of production, and reducing production costs.

Detailed implementation mode

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Embodiment 1: Please refer to Figure 1 - Figure 7 As shown, this embodiment is a die-casting mold for machining the end cover of an automotive steering motor, including an injection die segment 1. In the middle of one end of the injection die segment 1, an injection connection seat 3 is sleeved. A number of groups of material distribution valves 303 are arranged in a circular pattern on the outer periphery of the injection connection seat 3. In the middle of the other end of the injection die segment 1, an injection core 8 is nested. Inside the injection core 8, a number of groups of unloading push blocks 803 are arranged in a circular array at the central core. On the end face of the injection core 8, an injection splicing inner die segment 4 that is fitted and sleeved with the outer wall of the end face of the injection die segment 1 is provided. The injection splicing inner die segment 4 includes an injection segment one 401 and an injection segment two 402. The molten metal is pressurized and guided by an external injection device, and is guided into a number of groups of shunt valves through pipeline diversion. The shunt valve guides it into the injection hole 802 through a molten metal conduit. The injection hole 802 guides the molten metal to continuously fill the cavity between the injection core 8 and the die-casting core 7.

[0034] On the top and bottom of the injection die segment 1, a number of groups of locking grooves 101 are symmetrically recessed. On both sides of the injection die segment 1 and the die-casting die segment 2, a number of groups of matching side limit grooves 102 are symmetrically penetrated. At the four corners of the end faces of the injection die segment 1 and the die-casting die segment 2, sliding holes sleeved with the traveling guide rod 6 are symmetrically penetrated.

[0035] A fixed shaft seat 301 is fixedly arranged at the center of the end face of the injection connection seat 3. A number of groups of strengthening trays 302 connected to the distribution valve 303 one by one are arranged in an annular array on the outer periphery of the injection connection seat 3. A molten metal conduit connected to the injection mold core 8 and the injection splicing inner die lobe 4 is arranged inside the distribution valve 303. During the continuous injection of molten metal into the cavity between the injection mold core 8 and the compression mold core 7, the excess air in the cavity is extruded and guided along the air release ports on the injection mold core 8 and the compression mold core 7 to be shunted into the exhaust outer valve 203 and the exhaust valve 406. The air release ports and the cavity are specifically designed according to the model of the rotating motor end cover, not limited to the text and graphics. At the same time, a number of groups of spiral air ducts or spiral water pipes can be designed inside the injection mold core 8 and the compression mold core 7 according to the die-casting requirements of the rotating motor end cover, which is convenient for rapid cooling and shaping after the molten metal is poured into the cavity.

[0036] The injection lobe one 401 and the injection lobe two 402 have the same structure. A group of removable injection mold cores 8 are sleeved and embedded in the cores inside the injection lobe one 401 and the injection lobe two 402. A number of groups of valve replacement connection holes 403 are symmetrically arranged at the top of the injection lobe one 401 and the injection lobe two 402. Metal collar rings are arranged in the connection areas between the injection mold core 8 and the injection lobe one 401 and the injection lobe two 402. A number of groups of metal collar rings are sleeved and embedded in the inner wall of the injection mold lobe 1 at one time to construct a multi-level detachable replacement module on the end face of the injection mold lobe 1.

[0037] On both sides of one end of the injection lobe one 401 and the injection lobe two 402 facing the die-casting mold lobe 2, limit side frames 404 are symmetrically arranged. A convex strip 405 is slidably sleeved in the middle of the outer side wall of the limit side frame 404. A number of groups of exhaust valves 406 are symmetrically arranged at the bottom of the injection lobe one 401 and the injection lobe two 402.

[0038] The traveling guide rod 6 is sleeved inside the sliding hole of the die-casting mold lobe 2. The traveling guide rod 6 is provided with a matching sleeve rod 601 sleeved inside the sliding hole of the injection mold lobe 1. The matching sleeve rod 601 is provided with a cylinder kit 602 clamped to the inner wall of the sliding hole of the injection mold lobe 1. Along with the full injection and cooling and shaping treatment of the molten metal inside the cavity, it promotes the shaping of the molten metal in the cavity between the injection mold core 8 and the compression mold core 7. The traveling guide rod 6 is used in combination with an external hydraulic mechanism to pull the die-casting mold lobe 2 away from the injection mold lobe 1, constituting the pre-treatment of unloading the die-cast rotating motor end cover.

[0039] An annular disc 801 connected to the unloading push block 803 is arranged inside the injection mold core 8. A number of groups of injection holes 802 arranged annularly around the unloading push block 803 are arranged on the end face of the annular disc 801. When the injection mold core 8 is disconnected and unloaded, an adjusting cylinder connected to the unloading push block 803 is arranged inside the injection mold core 8. The adjusting cylinder drives the unloading push block 803 to run and extend synchronously. Along with the traction of the compression mold core 7 on the die-cast rotating motor end cover, it helps with the damage-free unloading treatment of the die-cast rotating motor end cover.

[0040] Embodiment 2: This embodiment is a die-casting mold for machining the end cover of an automotive steering motor. A die-casting die flap 2 is arranged side by side at one end of the injection die flap 1 close to the injection splicing inner die flap 4. A pressure-bearing push plate 201 is arranged in the middle of the end of the die-casting die flap 2 far from the injection die flap 1. An exhaust outer valve 203 is arranged on the outer wall of the pressure-bearing push plate 201. A die core 7 is sleeved and arranged in the middle of the end of the die-casting die flap 2 close to the injection die flap 1. A pressure splicing inner die flap 5 which is matched and sleeved with the outer wall of the end face of the die-casting die flap 2 is arranged on the end face of the die core 7. Travel guide rods 6 are symmetrically sleeved at the four corners of the end faces of the injection die flap 1 and the die-casting die flap 2.

[0041] In the middle of the end of the pressure-bearing push plate 201 far from the die-casting die flap 2, an explosion-proof shaft seat 202 is fixedly installed. A number of groups of side strengthening ribs 204 connected to the die-casting die flap 2 are arranged in a circumferential array on the outer periphery of the pressure-bearing push plate 201. A number of groups of communicating air guide pipes extending to the die core 7 are arranged inside the exhaust outer valve 203.

[0042] In the middle of the end of the die core 7 facing the injection die flap 1, a die pressing plate 701 is recessed. An inner push ring 703 is arranged in the middle of one end of the die pressing plate 701. A number of groups of foot push blocks 702 are arranged in a circumferential array on the inner wall edge of one end of the die pressing plate 701. The pressure splicing inner die flap 5 includes a pressure flap one 501 and a pressure flap two 502. Miniature cylinders are arranged inside the foot push blocks 702.

[0043] When the die-cast end cover of the steering motor is pulled by the die-casting mold to break away from the injection die flap 1, an external air supply device is connected to the exhaust outer valve 203 through a pipeline, and a negative pressure environment is constructed inside the die core 7 for pneumatically adsorbing the die-cast end cover of the steering motor to be temporarily adhered inside the die core 7. After the die-cast end cover of the steering motor completely breaks away from the injection die flap 1 and maintains a certain distance, the pneumatic adsorption treatment of the die-cast end cover of the steering motor is disconnected. A first propulsion cylinder connected to a number of groups of foot push blocks 702 is arranged inside the die core 7. The first propulsion cylinder extends and drives the foot push blocks 702 to extend towards the injection die flap 1. After the foot push blocks 702 contact the die-cast end cover of the steering motor, it is pushed to unload at multiple points. During this period, a second propulsion cylinder connected to the inner push ring 703 is arranged inside the die core 7. The second propulsion cylinder drives the inner push ring 703 to move synchronously with the foot push blocks 702 to perform a multi-point coordinated propulsion unloading treatment on the outer wall of the die-cast end cover of the steering motor.

[0044] After the unloading of the die-cast steering motor end cover is completed, if abnormal damage is found on the injection mold core 8 or the die mold core 7, the operation of the die-casting equipment is suspended. Through the crane equipped at the top of the die-casting equipment, the telescopic robotic arm of the crane approaches the damaged injection mold core 8 or die mold core 7. If the injection mold core 8 is damaged, the robotic arm approaches the valve-changing connection hole 403 above the injection mold core 8, inserts an adapter into the valve-changing connection hole 403, and rotates or magnetically fixes it. Unfasten the injection valve two 402 of the injection mold flap 1 facing the die-casting mold flap 2, disconnect the connection between the injection valve two 402 and the injection valve one 401, so that the injection valve two 402 is loosened. After the crane horizontally drives the injection valve two 402 to translate a certain distance, it is hoisted out of the die-casting equipment. Similarly, the die valve two 502 is disassembled synchronously for synchronous cleaning and maintenance to facilitate targeted repair;

[0045] After the injection valve one 401 loses the restriction of the injection valve two 402, adjust the fitting distance between the die-casting mold flap 2 and the injection mold flap 1, so that the injection valve one 401 and the die valve one 501 are used in combination for die-casting the molten metal, to avoid long-term shutdown for maintenance caused by damage to the bodies of the injection mold flap 1 and the die-casting mold flap 2.

[0046] Combining Embodiment 1 and Embodiment 2, the die-casting mold for processing the automotive steering motor end cover designed by the present invention has many advantages. Through an external injection device combined with a flow control valve, etc., the injection is accurate and uniform, avoiding product defects and improving quality stability.

[0047] The air vent is set according to the end cover model and is equipped with an internal spiral tube to improve exhaust and cooling, enhance product performance, shorten the production cycle, and the demolding and unloading mechanism is diverse and reliable, ensuring safety and stability and achieving damage-free unloading; the design of the crane and the valve-changing connection hole 403 makes the mold maintenance convenient. During maintenance, some molds can continue to operate, reducing downtime and costs.
