Description

Technical Field

[0001] The invention relates to the technical field of automobile parts processing, in particular to a die-casting mold for processing an automobile steering motor end cover. Background Art

[0002] As a key component of the automobile steering system, the automobile steering motor end cover plays an important role in the steering performance and safe operation of the automobile. In recent years, with the rapid development of the automobile industry, the demand for automobile steering motor end covers has continued to rise. At the same time, consumers and automobile manufacturers have also put forward more stringent requirements on their quality and production efficiency. Against this background, the die-casting mold technology based on the processing of automobile steering motor end covers came into being and continued to develop and innovate.

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

[0004] In conjunction with the above, it should be noted that: Chinese patent application number CN2023236284528 discloses a die-casting mold for a power steering motor housing. The ejector plate provided during ejection is different from the ejector column with a smaller ejection area. The ejector plate can disperse the ejection force, so that the molded product has a large force-bearing area, preventing deformation due to ejection, and then ejecting the product.

[0005] In fact, during the demolding of the automobile steering motor end cover die-casting, the arrangement of metal castings according to a reasonable mold cavity structure can greatly avoid the problem of demolding difficulties. What's more, the hardness of the steering motor end cover casting body after cooling and the viscosity generated by the pressure between it and the inner wall of the mold cavity during molding cause the steering motor end cover to be demolded and cause damage to the inner wall of the mold cavity. The traditional mold is an integrated structure. Therefore, the overall repair of the internal damage of the mold is difficult and time-consuming, affecting the subsequent overall steering motor end cover processing efficiency.

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

The injection splicing inner mold flap 4 includes an injection flap 1 401 and an injection flap 2 402. The molten metal is pressurized and guided by an external injection equipment, and enters the interior of several groups of diversion valves combined with pipeline diversion. The diversion valve guides the molten metal to the injection hole 802 through the metal liquid conduit. The injection hole 802 guides the metal liquid to continuously fill the cavity between the injection mold core 8 and the compression mold core 7.

[0034] Several groups of locking grooves 101 are symmetrically recessed on the top and bottom of the injection mold half 1, and several groups of cooperating side limit grooves 102 are symmetrically set through both sides of the injection mold half 1 and the die-casting mold half 2. Sliding holes that are connected to the travel guide rod 6 are symmetrically set through the four corners of the end faces of the injection mold half 1 and the die-casting mold half 2.

[0035] A fixed shaft seat 301 is fixedly provided at the center of the end face of the injection connecting seat 3, and a circular array on the outer periphery of the injection connecting seat 3 is provided with several groups of reinforced trays 302 connected one by one with the distribution valve 303. A metal liquid conduit connected to the injection mold core 8 and the injection splicing inner mold flap 4 is provided inside the distribution valve 303. During the period when the metal liquid is continuously injected into the cavity between the injection mold core 8 and the compression mold core 7, the excess air in the cavity is squeezed and guided along the vent ports on the injection mold core 8 and the compression mold core 7 to the exhaust outer valve 203 and the exhaust valve 406. The vent port and the cavity are designed according to the model of the steering motor end cover and are not limited to graphic limitations. At the same time, the inside of the injection mold core 8 and the compression mold core 7 can be designed with several groups of spiral air ducts or spiral water pipes according to the die-casting needs of the steering motor end cover, so as to facilitate rapid cooling and shaping after the metal liquid is poured into the cavity.

[0036] The injection flap 1 401 and the injection flap 2 402 have the same structure. A group of movable and detachable injection mold cores 8 are embedded in the inner core of the injection flap 1 401 and the injection flap 2 402. Several groups of petal replacement connection holes 403 are symmetrically arranged on the top of the injection flap 1 401 and the injection flap 2 402. Metal rings are provided in the connection areas between the injection mold core 8 and the injection flap 1 401 and the injection flap 2 402. Several groups of metal rings are socketed and embedded in the inner wall of the injection mold flap 1 at one time, and a multi-level detachable replacement module is constructed on the end face of the injection mold flap 1.

[0037] Limiting side frames 404 are symmetrically arranged on both sides of the injection flap 1 401 and the injection flap 2 402 facing one end of the die-casting mold flap 2, and a convex strip 405 is slidably sleeved on the middle part of the outer wall of the limiting side frame 404. Several groups of exhaust valves 406 are symmetrically arranged on the bottom of the injection flap 1 401 and the injection flap 2 402.

[0038] The traveling guide rod 6 is sleeved inside the sliding hole of the die-casting mold half 2. The traveling guide rod 6 is provided with a matching sleeve rod 601 which is sleeved inside the sliding hole of the injection mold half 1. The matching sleeve rod 601 is provided with a cylinder kit 602 which is clamped with the inner wall of the sliding hole of the injection mold half 1. With the full filling and cooling of the metal solution inside the cavity, the metal solution is shaped in the cavity between the injection mold core 8 and the compression mold core 7. The traveling guide rod 6 is used in conjunction with the external hydraulic mechanism to pull the die-casting mold half 2 away from the injection mold half 1, constituting a prelude to the unloading processing of the die-cast steering motor end cover.

[0039] The injection mold core 8 is provided with a mold ring disk 801 connected to the unloading push block 803 inside, and the end face of the mold ring disk 801 is provided with several groups of injection holes 802 arranged in a ring around the unloading push block 803. When the injection mold core 8 is disconnected and unloaded, the injection mold core 8 is provided with an adjusting cylinder connected to the unloading push block 803. The adjusting cylinder drives the unloading push block 803 to run and extend synchronously, and is used in conjunction with the traction of the die-cast steering motor end cover by the die-cast core 7, which is conducive to the damage-free unloading of the die-cast steering motor end cover.

[0040] Embodiment 2: This embodiment is a die-casting mold for processing the end cover of an automobile steering motor, comprising an injection mold flap 1 and a die-casting mold flap 2 arranged side by side at one end thereof close to the injection splicing inner mold flap 4, a pressure-bearing push plate 201 is provided in the middle of the end of the die-casting mold flap 2 away from the injection mold flap 1, an exhaust outer valve 203 is provided on the outer wall of the pressure-bearing push plate 201, a die core 7 is nested in the middle of the end of the die-casting mold flap 2 close to the injection mold flap 1, a die core 7 is provided on the end face of the die core 7 and a splicing inner mold flap 5 which is fitted with the outer wall of the end face of the die-casting mold flap 2 is provided, and a travel guide rod 6 is symmetrically fitted at the four corners of the end faces of the injection mold flap 1 and the die-casting mold flap 2.

[0041] An explosion-proof shaft seat 202 is fixedly installed in the middle of the end of the pressure push plate 201 away from the die-casting mold 2. A circular array on the outer periphery of the pressure push plate 201 is provided with several groups of side reinforcing ribs 204 connected to the die-casting mold 2, and the exhaust outer valve 203 is internally provided with several groups of connecting air ducts extending to the die core 7.

[0042] A die plate 701 is provided in the middle depression of the die core 7 facing one end of the injection mold flap 1, an inner push ring 703 is provided in the middle of one end of the die plate 701, and a plurality of foot push blocks 702 are provided in a circular array on the inner wall edge of one end of the die plate 701. The spliced ​​inner mold flap 5 includes a flap 1 501 and a flap 2 502, and a micro cylinder is provided inside the foot push block 702.

[0043] When the die-casting mold pulls the die-cast steering motor end cover out of the injection mold 1, the external air supply equipment is connected to the exhaust valve 203 pipeline, and a negative pressure environment is constructed inside the die core 7 for pneumatically adsorbing the die-cast steering motor end cover to temporarily adhere to the inside of the die core 7. After the die-cast steering motor end cover is completely separated from the injection mold 1 and maintains a certain distance, the pneumatic adsorption treatment of the die-cast steering motor end cover is disconnected. A propulsion cylinder 1 connected to several groups of foot push blocks 702 is provided inside the die core 7. The propulsion cylinder 1 extends and carries the foot push blocks 702 toward the injection mold 1. After the foot push blocks 702 contact the die-cast steering motor end cover, they are pushed and unloaded in a multi-point manner. During this period, a propulsion cylinder 2 connected to the inner push ring 703 is provided inside the die core 7. The propulsion cylinder 2 drives the inner push ring 703 and the foot push blocks 702 to move synchronously, and performs multi-point coordinated propulsion and unloading treatment on the outer wall of the die-cast steering motor end cover.

[0044] After the unloading of the die-cast steering motor end cover is completed, if the injection mold core 8 or the compression mold core 7 is found to be abnormally damaged, the operation of the die-casting equipment is suspended, and the crane equipped on the top of the die-casting equipment extends the mechanical arm close to the damaged injection mold core 8 or compression mold core 7. If the injection mold core 8 is damaged, the mechanical arm approaches the petal replacement connection hole 403 above the injection mold core 8, and is inserted into the petal replacement connection hole 403 through an adaptive connector, and is rotated and connected or fixed by electromagnetic suction, and the injection petal 2 402 located at the injection mold petal 1 facing the compression mold petal 2 is released, and the connection between the injection petal 2 402 and the injection petal 1 401 is disconnected, so that the injection petal 2 402 is loosened, and the crane drives the injection petal 2 402 horizontally for a distance, and then lifts it out of the die-casting equipment. Similarly, the compression petal 2 502 is disassembled simultaneously for simultaneous cleaning and maintenance, so as to facilitate targeted maintenance treatment.

[0045] After injection flap 1 401 loses the restriction of injection flap 2 402, the fitting distance between the die-casting mold flap 2 and the injection mold flap 1 is adjusted, so that injection flap 1 401 and pressure flap 1 501 are used in conjunction to perform die-casting on the metal solution, so as to avoid long-term shutdown and maintenance caused by damage to the injection mold flap 1 and the die-casting mold flap 2.

[0046] In combination with Example 1 and Example 2, the die-casting mold for processing the automobile steering motor end cover designed by the present invention has many advantages. Through external injection equipment combined with a diverter valve, etc., accurate and uniform injection can be achieved, thus avoiding product defects and improving quality stability.

[0047] Air vents are designed according to the end cap model and are equipped with internal spiral tubes to improve exhaust and cooling, enhance product performance, and accelerate production cycles. The demoulding and unloading mechanisms are diverse and reliable, ensuring safe, smooth, and lossless unloading. The design of the 403-hole connection between the crane and the valve replacement makes mold maintenance convenient. During maintenance, some molds can continue to operate, reducing downtime and lowering costs.
