Description

Technical Field

[0001] This invention belongs to the field of die casting mold technology, specifically relating to a slider mechanism, a die casting mold, and a die casting method. Background Technology

[0002] In the field of die-casting mold processing, workpieces commonly have undercut structures. To ensure smooth demolding, a slider mechanism is required. This mechanism's drive structure moves the slider away from the demolding direction, avoiding interference from the undercut structure and ensuring normal demolding production. When the undercut structure has a special location or complex forming angle, relying solely on a drive component to move the slider in a single linear reciprocating motion is insufficient to meet the demolding trajectory requirements. In such cases, traditional slider mechanisms typically employ a dual-drive component combination drive structure. This type of structure uses two drive components arranged crosswise and moving sequentially to drive the same slider to complete multi-directional displacement movements, thus adapting to the demolding trajectory requirements of special undercuts and completing the workpiece demolding operation.

[0003] However, the traditional dual-drive slider structure has significant drawbacks. The arrangement of multiple drive components will greatly increase the overall structural complexity of the slider mechanism, resulting in more assembly parts and a bulky overall size. This not only significantly increases the processing, assembly and maintenance costs of the slider mechanism, but also occupies more internal installation space in the die-casting mold, leading to an increase in the overall size of the die-casting mold and structural redundancy. This reduces the space utilization rate and production adaptability of the die-casting mold, which is not conducive to the design and production application of miniaturized and precision die-casting molds. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a slider mechanism, a die-casting mold and a die-casting molding method in light of the current state of the prior art.

[0005] The technical solution adopted by this invention to solve the above-mentioned technical problems is as follows: a die-casting molding method is proposed, comprising the following steps: S1. The drive unit starts working, and the connecting part of the drive slider moves smoothly along the straight guide section of the non-linear trajectory groove, driving the slider to move in a straight line until the slider moves to the preset mold closing initial position, completing the initial displacement alignment. S2. As the driving component continues to drive the slider displacement, the connecting part smoothly transitions from the straight guide section to the arc guide section. The driving component continues to drive the slider to move, causing the slider to rotate adaptively relative to the moving mold assembly until the slider completely fits the moving mold assembly. S3. The moving mold assembly drives the slider mechanism to move towards the fixed mold assembly until the moving mold assembly and the fixed mold assembly are completely abutted and fitted together, and the product cavity formed by the slider structure is completed to complete the mold closing process. S4. Molten metal is injected at high speed into the closed product cavity through the die-casting equipment. After the molten metal fills the cavity, it is held under pressure and cooled to obtain a die-cast workpiece with an undercut structure. S5. After the workpiece has cooled and formed, the moving mold assembly drives the overall slider mechanism away from the fixed mold assembly, completing the initial mold opening action and causing the fixed mold to separate from the workpiece. S6. After the mold opening is completed, the drive unit starts working in reverse, driving the slider to rotate in the opposite direction, causing the connecting part of the slider to move in the opposite direction along the arc guide section, driving the slider to rotate and move away from the product cavity. S7. The driving component continuously reverses the driving of the slider, causing the connecting part to re-enter the straight guide section from the arc guide section, driving the slider to make a straight reset movement until the slider returns to the preset initial position, at which point the formed workpiece can be taken out and the next die-casting cycle can begin.

[0006] The present invention also proposes a slider mechanism for implementing the above-mentioned forming method, which solves the above-mentioned technical problems, including: a fixed base on which a non-linear trajectory groove is provided; A slider is movably connected to the fixed base, and the slider is provided with a connecting part that cooperates with the nonlinear trajectory groove; A driving component is rotatably connected to the fixed base, and the output end of the driving component is rotatably connected to the slider; wherein, The driving component is used to drive the connecting part to move along the nonlinear trajectory groove, so that the slider generates a composite motion.

[0007] In one of the aforementioned slider mechanisms, the nonlinear trajectory groove includes interconnected arc-shaped guide sections and straight guide sections; wherein, When the connecting part moves within the arc-shaped guide section, the slider rotates and moves simultaneously relative to the fixed seat; When the connecting part moves within the linear guide section, the slider moves linearly relative to the fixed seat.

[0008] In one of the aforementioned slider mechanisms, the driving member is rotatably connected to the fixed base at a pivot point; wherein... The pivot point of the drive member is positioned such that when the output end of the drive member pushes the slider, the connecting part can move sequentially along the arc-shaped guide segment and the straight guide segment.

[0009] In one of the slider mechanisms described above, the slider is provided with a groove and a detachable locking block; The locking block covers the groove and together with the groove forms a rotating pair for accommodating the rotational connection of the output end of the drive component; the locking block is used to limit the axial displacement of the rotating pair.

[0010] In one of the slider mechanisms described above, the connecting part is at least one rolling element disposed on the slider, and the rolling element is rotatably disposed within the nonlinear trajectory groove.

[0011] In one of the slider mechanisms described above, a chip removal groove is provided on the fixed base. The first end of the chip removal groove extends to the end of the fixed base and communicates with the outside. The second end of the chip removal groove communicates with the nonlinear trajectory groove.

[0012] In one of the slider mechanisms described above, a connecting seat is further provided on the fixed base. The connecting seat is rotatably provided on the fixed base via a rotating shaft. The driving member is connected to the connecting seat to provide support for the driving member.

[0013] In addition to solving the above-mentioned technical problems, the present invention also proposes a die-casting mold, including the aforementioned slider mechanism.

[0014] The aforementioned die-casting mold further includes a fixed mold assembly and a moving mold assembly that are movably fitted together. The slider mechanism is connected to the moving mold assembly, and a product cavity is formed between the fixed mold assembly, the slider, and the moving mold assembly. The moving mold assembly is provided with a positioning protrusion, and the slider is provided with a positioning hole that matches the positioning protrusion. The positioning protrusion has an inclined surface at one end facing the product cavity, which is used to allow the positioning protrusion to be embedded into the positioning hole when the slider moves in the direction of the product cavity.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) By setting a fixed seat with a nonlinear trajectory groove, a slider that is movably connected to the fixed seat and equipped with a matching nonlinear trajectory groove connection part, and a drive component that is rotatably mounted on the fixed seat and whose output end is rotatably connected to the slider, the integrated single drive structure that drives the connection part to move along the nonlinear trajectory groove to generate compound motion of the slider solves the problems of traditional slider mechanism that requires two drive components to be configured for time-sharing cross-drive, complex structure, large overall mold volume, and high manufacturing cost. Only a single drive component is used to realize the multi-directional compound demolding action of the slider, greatly reducing the number of parts, reducing the overall size of the mechanism, and reducing the processing and assembly costs of the slider mechanism and the die-casting mold.

[0017] (2) The nonlinear trajectory groove is composed of connected arc-shaped guide segments and straight guide segments. The pivot point of the driving component is matched with the trajectory so that the connecting part passes through the arc-shaped and straight guide segments in sequence. When the arc segment moves, the slider rotates and moves synchronously. When the straight segment moves, the slider only moves in a straight line. This segmented trajectory constraint structure solves the problem that a single straight drive cannot adapt to the special undercut complex demolding trajectory and is prone to interference and jamming with the undercut of the workpiece during demolding. The segmented trajectory can accurately control the timing and form of the slider movement. First, rotate to avoid the undercut and then pull the core in a straight line. The demolding action is continuous and smooth, avoiding workpiece damage and deformation, and improving the molding yield of die-cast products.

[0018] (3) A groove is opened in the slider and a detachable locking block is provided. The locking block and the groove form a split rotating connection structure that accommodates the rotating pair of the output end of the drive component and restricts the axial displacement of the rotating pair. This solves the problems of easy axial movement at the rotating joint of the drive component and the slider, large gap leading to slider movement deviation, and poor demolding positioning accuracy. The locking block can constrain the axial displacement of the drive end, ensure the coaxiality of the transmission and the accuracy of the movement. At the same time, the locking block is detachable, which is convenient for later disassembly, maintenance and replacement of worn parts, and reduces the difficulty of operation and maintenance of the mechanism.

Detailed Implementation

[0027] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0028] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0029] This embodiment discloses a slider mechanism 300 and a die-casting mold and die-casting method using it. The slider mechanism 300 is suitable for demolding conditions of various die-casting molds with complex undercut structures. It effectively solves the technical defects of traditional dual-drive slider mechanisms, such as complex structure, bulky size, high manufacturing cost, and large overall mold volume. It relies on a single drive component 330 in conjunction with a nonlinear trajectory groove 311 to achieve the composite motion of the slider 320, which can accurately adapt to the demolding trajectory of special undercut workpieces. It has the advantages of simple structure, small size, high demolding accuracy, stable operation, and low cost, and can be widely adapted to the molding and demolding production needs of various precision die-casting workpieces.

[0030] Specifically, referring to Figures 1 to 7, the slider mechanism 300 includes a fixed base 310, a slider 320, and a driving member 330.

[0031] The fixed base 310 is the basic mounting and bearing component of the mechanism, used to assemble and position the various parts; the fixed base 310 is provided with a nonlinear trajectory groove 311 to provide trajectory constraints for the composite motion of the slider 320.

[0032] The slider 320 is movably mounted on the fixed base 310. The slider 320 is provided with a connecting part 321 that is adapted to the nonlinear trajectory groove 311. The movement trajectory of the slider 320 is limited by the cooperation between the connecting part 321 and the nonlinear trajectory groove 311.

[0033] In one embodiment, the fixing base 310 includes two main body plates arranged opposite to each other, and a connecting plate connected to the same side of the two main body plates; the connecting plate is locked to the two main body plates by threaded fasteners to form the main structure of the fixing base 310.

[0034] Nonlinear trajectory grooves 311 are provided on the side walls of the two main plates facing each other. Correspondingly, connecting parts 321 are provided on both sides of the slider 320. The number of nonlinear trajectory grooves 311 on one side of the main plate is consistent with the number of connecting parts 321 on the same side of the slider 320. Both can be set to one or two.

[0035] The drive component 330 is rotatably mounted on the fixed base 310, and the output end of the drive component 330 is hinged to the slider 320. With the power output by the drive component 330, the connecting part 321 of the slider 320 can slide along the nonlinear trajectory groove 311 throughout the entire process, so that the slider 320 can synchronously complete the combined motion of rotation and linear displacement, which meets the demolding operation requirements of workpieces with special undercut structures. Preferably, the drive component 330 is a hydraulic cylinder.

[0036] As the core optimized structure of this solution, the nonlinear trajectory groove 311 on the fixed seat 310 is composed of interconnected arc-shaped guide sections 311a and straight guide sections 311b. The arc-shaped guide sections 311a and straight guide sections 311b are smoothly connected without any motion jamming or dead angles, ensuring the continuity and stability of the slider 320's movement.

[0037] During actual movement, when the connecting part 321 of the slider 320 moves along the internal trajectory of the arc-shaped guide section 311a, the slider 320 can simultaneously complete the combined rotation and translation actions relative to the fixed seat 310 under the constraint of the arc-shaped trajectory, adapting to the angle avoidance requirements of the workpiece undercut position.

[0038] When the connecting part 321 switches to the internal movement of the linear guide section 311b, the linear guide section 311b forms a single axial constraint on the slider 320, restricting the rotational degree of freedom of the slider 320, so that the slider 320 only makes a stable linear reciprocating motion relative to the fixed seat 310, and completes the main demolding displacement action.

[0039] In this solution, the slider 320 first rotates to avoid obstacles and then moves linearly to achieve a step-by-step demolding action through the cooperation of two different guide structures, which perfectly adapts to the demolding trajectory of complex undercuts.

[0040] Specifically, the drive component 330 is rotatably mounted on the fixed base 310 at a preset pivot point. The position of the pivot point is precisely matched and designed to match the trajectory of the arc-shaped guide section 311a and the straight guide section 311b of the nonlinear trajectory groove 311.

[0041] This structural arrangement ensures that during the rotation and oscillation of the drive component 330 around the pivot point and the continuous pushing of the slider 320 by its output end, the connecting part 321 of the slider 320 can move smoothly along the arc-shaped guide section 311a and the straight guide section 311b in strict accordance with the preset sequence, accurately replicating the preset composite motion trajectory, eliminating the problems of disordered motion sequence and trajectory deviation, and ensuring the accuracy and consistency of demolding action.

[0042] In this design, the slider 320 is provided with a groove 322 and a detachable locking block 323. The locking block 323 is detachably mounted on the groove 322 of the slider 320. The locking block 323 and the groove 322 cooperate with each other to form a rotating pair structure. The output end of the drive member 330 is rotatably mounted inside the rotating pair to realize the rotational connection between the drive member 330 and the slider 320.

[0043] Meanwhile, the locking block 323 can effectively limit the axial movement and offset of the rotating pair, completely restricting the axial movement and offset of the output end of the drive component 330. This avoids the problem of motion shaking and reduced demolding accuracy caused by excessive clearance between the drive end and the slider 320, greatly improving the stability and matching accuracy of the drive transmission. In addition, the detachable locking block 323 structure facilitates the disassembly, maintenance and replacement of parts in the later stage.

[0044] Preferably, the connecting portion 321 on the slider 320 is configured as at least one rolling element, which is rotatably assembled inside the nonlinear trajectory groove 311.

[0045] The rolling element and the track groove are in rolling friction fit, which can significantly reduce the frictional resistance of the connecting part 321 during the movement of the nonlinear track groove 311, effectively reduce the wear of parts, avoid jamming and sticking faults in long-term reciprocating motion, improve the smoothness of the movement of the slider 320 and the service life of the mechanism, and further ensure the smoothness of the demolding action.

[0046] Furthermore, a chip removal groove 312 is provided on the fixed base 310. The chip removal groove 312 adopts a through-type layout structure, with its first end extending to the end of the fixed base 310 and communicating with the outside air, and its second end communicating with the inside of the nonlinear trajectory groove 311.

[0047] Metal chips and oil impurities generated during the die casting process can be discharged from the nonlinear trajectory groove 311 in a timely manner through the chip removal groove 312 during the reciprocating motion of the slider 320. This effectively avoids problems such as track groove blockage, rolling component jamming, and motion trajectory deviation caused by impurity accumulation, continuously ensuring the cleanliness and transmission accuracy of the nonlinear trajectory groove 311, reducing the failure rate of the mechanism, and adapting to the long-term high-frequency production conditions of die casting molds.

[0048] The slider mechanism 300 is also equipped with a connecting seat 340, which is rotatably mounted on the fixed seat 310 via a rotating shaft. The driving component 330 is fixedly installed on the connecting seat 340, and the connecting seat 340 provides a stable installation support reference for the driving component 330.

[0049] This structure allows the drive component 330 to rotate slightly with the connecting seat 340 to adapt to the overall rotation, further matching the composite motion trajectory of the slider 320, reducing the assembly stress of the drive component 330, improving the overall stability and structural adaptability of the drive structure, and facilitating the positioning, assembly and angle fine-tuning of the drive component 330.

[0050] This solution also discloses a die-casting mold, which is equipped with the slider mechanism 300 described in any of the above embodiments. Specifically, it includes a fixed mold assembly 100 and a moving mold assembly 200 that move and cooperate with each other. The slider mechanism 300 is fixedly assembled on the moving mold assembly 200. The fixed mold assembly 100, the slider 320 and the moving mold assembly 200 cooperate with each other to form a product cavity for workpiece forming.

[0051] The moving mold assembly 200 is integrally formed or fixedly assembled with a positioning protrusion 210, and the slider 320 is provided with a positioning hole 324 that is precisely matched with the positioning protrusion 210. The positioning protrusion 210 and the positioning hole 324 are connected and engaged to achieve precise positioning of the slider 320 when the mold is closed.

[0052] Meanwhile, the end of the positioning protrusion 210 facing the product cavity is provided with a guide slope. During the mold closing process of the slider 320 moving towards the product cavity, the guide slope can play a role in precise guidance and adaptive correction, guiding the positioning protrusion 210 to be smoothly embedded into the positioning hole 324, effectively eliminating the positioning deviation caused by the assembly gap, and ensuring the mold closing accuracy and product molding quality.

[0053] This solution also discloses a die-casting molding method based on the above-mentioned die-casting mold, which specifically includes the following molding steps: S1. The drive unit 330 starts working, driving the connecting part 321 of the slider 320 to move smoothly along the straight guide section 311b of the nonlinear trajectory groove 311, driving the slider 320 to make precise linear movement until the slider 320 moves to the preset mold closing initial position, completing the initial displacement alignment. S2. As the driving component 330 continues to drive the slider 320 to move, the connecting part 321 smoothly transitions from the straight guide section 311b to the arc guide section 311a. Relying on the trajectory constraint of the arc guide section 311a, the driving component 330 continues to drive the slider 320 to move, so that the slider 320 rotates adaptively relative to the moving mold assembly 200 until the slider 320 is completely in contact with the moving mold assembly 200. S3. The moving mold assembly 200 drives the slider mechanism 300 to move smoothly toward the fixed mold assembly 100 until the moving mold assembly 200 and the fixed mold assembly 100 are completely abutted and fitted together, forming a sealed and complete product cavity with the slider 320 structure, thus completing the mold closing process. S4. Molten metal is injected at high speed into the closed product cavity through the die-casting equipment. After the molten metal fills the cavity, it is held under pressure and cooled to allow the molten metal to solidify and form quickly, resulting in a die-cast workpiece with an undercut structure. S5. After the workpiece is cooled and formed, the moving mold assembly 200 drives the overall slider mechanism 300 away from the fixed mold assembly 100, completing the initial mold opening action and causing the fixed mold to initially separate from the workpiece. S6. After the mold is opened, the drive component 330 starts working in reverse, driving the slider 320 to rotate in reverse, causing the connecting part 321 of the slider 320 to move in reverse along the arc guide section 311a, driving the slider 320 to rotate and move away from the product cavity, making angular avoidance to the undercut structure of the workpiece, and completely eliminating the interference limit between the slider 320 and the undercut of the workpiece. S7. The driving component 330 continuously drives the slider 320 in the reverse direction, causing the connecting part 321 to re-enter the straight guide section 311b from the arc-shaped guide section 311a, driving the slider 320 to perform a straight reset movement until the slider 320 returns to the preset initial position, completing the entire demolding and reset process. The molded workpiece can then be removed and the next die-casting cycle can begin.

[0054] This invention adopts a composite motion structure design with a single drive component 330 and a nonlinear trajectory groove 311. Compared with the traditional demolding mechanism with dual drive components 330 and slider 320, it completely eliminates the complex structure mode of multiple drive components 330 arranged in a cross pattern and driven in a time-sharing manner, greatly reduces the number of mechanism parts, simplifies the assembly structure, effectively reduces the overall volume of slider mechanism 300, and significantly reduces the processing, assembly and maintenance costs of the mechanism.

[0055] Meanwhile, through the segmented trajectory design of the arc-shaped guide section 311a and the linear guide section 311b, the composite demolding action of the slider 320 first rotating to avoid and then linearly displacing is accurately realized. This perfectly adapts to the demolding requirements of complex undercut workpieces, with high demolding accuracy and good action stability. It effectively solves the problems of demolding jamming, interference and poor accuracy of traditional mechanisms. It can effectively reduce the overall volume of the die-casting mold, improve the mold space utilization and production adaptability, and adapt to the mass production needs of precision miniaturized die-casting workpieces.
