Die casting mold and method with side slide

Abstract

This invention discloses a die-casting mold and method with side sliders, relating to the field of die-casting mold design technology. The die-casting mold with side sliders includes a stationary mold and a moving mold. The moving mold is equipped with an ejector rod, and at least three slots are opened on the side of the moving mold. The inner wall of the slots facing the inner cavity of the moving mold is an "eight"-shaped inclined surface. This die-casting mold with side sliders, by opening slots on the moving mold side and matching them with side sliders, allows the inclined pressing surface at the end of the side slider to precisely conform to the inclined surface of the product during the mold closing and forming stage. In the initial stage of mold opening, the side slider is kept in a stable locked state by locking components. The inclined pressing surface forcibly presses and limits the formed product to the moving mold side, ensuring that the product moves synchronously with the moving mold during mold opening and smoothly separates from the stationary mold. This fundamentally avoids the problem of product wrapping around the stationary mold, demolding failure, and product scrap caused by the small difference in the wrapping force between the moving and stationary molds, significantly improving the continuity of die-casting production and the product qualification rate.

Description

Technical Field

[0001] This invention relates to the field of die casting mold design technology, specifically to a die casting mold and method with side slides. Background Technology

[0002] Die casting is a precision casting process that uses high pressure to force molten metal into a mold cavity to form a shape. With its advantages of high forming efficiency, good product dimensional accuracy, and suitability for mass production, it is widely used in the manufacturing of aluminum alloy industrial parts. In the mold opening stage of die casting production, it is essential to ensure that the formed product is stably wrapped around the moving mold side, moving synchronously with the moving mold to complete the separation from the stationary mold. Then, the product is demolded through the ejection mechanism built into the moving mold. This is the core step in ensuring the continuity of die casting production, product yield, and production efficiency.

[0003] In actual die casting production, when the product structure results in a small difference in the wrapping force between the moving mold and the stationary mold, abnormal situations such as product sticking and wrapping on the stationary mold side are very likely to occur when the mold is opened. This can not only cause product deformation and scrap, but may also cause scratches and damage to the mold cavity, seriously affecting production efficiency and product qualification rate. This is an industry pain point that urgently needs to be solved in the field of die casting mold design.

[0004] Regarding the aforementioned static mold sticking problem, the mainstream solutions in the industry currently fall into two categories:

[0005] The first approach involves adjusting the product's demolding angle. This is achieved by decreasing the demolding angle on the moving mold side and increasing the demolding angle on the stationary mold side, thereby increasing the wrapping force of the moving mold on the product and forcing the product to move with the moving mold during mold opening. However, this solution requires modification of the product's original structure. Since the product structure has typically undergone CAE modal analysis and performance verification, and customers explicitly prohibit changes to the product structure, this solution faces significant limitations in practical production and cannot be widely applied.

[0006] The second type involves adding an independent ejection system to the stationary mold side. This involves installing ejector pins and rods within the stationary mold to force the product out of the cavity during mold opening, preventing the product from sticking to the mold. However, this approach has significant drawbacks: the addition of the ejection system greatly increases the overall thickness of the stationary mold, directly reducing the filling degree of the die-casting machine's barrel, affecting the filling effect of the molten aluminum, and consequently lowering the internal forming quality of the product. Furthermore, the addition of the stationary mold ejection system significantly increases the structural complexity of the mold, raising manufacturing costs and making subsequent maintenance more difficult, which is detrimental to cost control for the company.

[0007] Currently, there is no mature solution in the industry that can effectively solve the problem of static mold sticking without modifying the product structure or adding a static mold ejection system. Therefore, developing a die-casting mold that is compatible with existing die-casting production lines and does not affect product performance and molding quality has significant production application value. Summary of the Invention

[0008] The purpose of this invention is to provide a die-casting mold and method with a side slide block, to solve the problems mentioned in the background art. To achieve the above objective, this invention provides the following technical solution: a die-casting mold with a side slide block, comprising a stationary mold and a moving mold, wherein the moving mold is provided with an ejector rod.

[0009] The moving mold has at least three slots on its side, and the inner wall of the slot facing the inner cavity of the moving mold is an "eight" shaped bevel; a side slider is inserted into the slot.

[0010] The side slider has an inclined surface at the end facing the inner cavity of the moving mold for fitting with the inclined surface of the slot, and an inclined pressing surface for fitting with the inclined surface of the product and stably limiting the product in the moving mold;

[0011] The side slider is provided with a locking element for locking the side slider in the working position within the slot;

[0012] The side slider is configured to remain stationary during the initial mold opening stage to force the product into the moving mold, thereby reliably separating the product from the stationary mold.

[0013] Preferably, the locking component includes a fixed sleeve, a sliding lock sleeve, a locking block, an auxiliary spring telescopic rod, and a slot;

[0014] The fixed sleeve is fixedly installed in the slot, and the sliding lock sleeve is slidably inserted into the inner wall of the fixed sleeve. The end of the sliding lock sleeve facing the inner cavity of the moving mold is fixedly connected to the side slider. The locking blocks are symmetrically arranged on the upper and lower sides of the inner wall of the sliding lock sleeve. The left and right sides of the locking blocks are hinged with auxiliary spring telescopic rods arranged in a figure-eight shape. The other end of the auxiliary spring telescopic rods is hinged to the inner wall of the sliding lock sleeve. The fixed sleeve has a slot on the inner side. The locking block is inserted into the slot under the elastic force of the auxiliary spring telescopic rod to realize the axial locking between the sliding lock sleeve and the fixed sleeve.

[0015] Preferably, the abutting end of the locking block is fitted with balls for reducing sliding friction.

[0016] Preferably, guide grooves are provided on both the upper and lower sides of the sliding lock sleeve, and a retraction rod for pulling the side slider to reset is provided inside the sliding lock sleeve;

[0017] One end of the resetting spring retraction rod is fixedly connected to the side slider, and the other end passes through the guide groove and is fixedly connected to the inner wall of the fixed sleeve.

[0018] Preferably, the sliding lock sleeve is further provided with an unlocking component for releasing the locking state of the locking block and the slot; the unlocking component includes an inner push block, a return spring, a U-shaped groove, an L-shaped guide plate, a guide plate, a torsion spring, a one-way locking block and a shaft;

[0019] The inner push block is slidably disposed inside the sliding lock sleeve, and a reset spring is fixedly connected between the inner push block and the side slider.

[0020] The inner push block has U-shaped grooves on both the upper and lower sides. The inner wall of the U-shaped groove is fixedly connected to L-shaped guide plates arranged symmetrically in front and behind. The L-shaped guide plates are hinged to guide plates. A torsion spring is provided between the guide plates and the L-shaped guide plates to keep the guide plates in their initial position. A one-way locking block is fixed at the hinge end of the guide plates to prevent deflection when the plates are squeezed to unlock.

[0021] The shaft is fixed to the end of the locking block away from the slot; the inner push block is configured to move under external thrust, and squeezes the shaft through the guide plate, causing the locking block to exit the slot and unlock.

[0022] Preferably, the slot width can be adjusted according to the product size, and the side slider size is adapted to the slot.

[0023] A method for using a die-casting mold with a side slide block includes the following steps:

[0024] S1. Slider pre-locking before mold closing: After mold preheating and mold release agent spraying are completed, the external robot pushes the sliding lock sleeve to slide inward along the fixed sleeve, driving the side slider to move along the slot to the working position. The inclined surface of the side slider fits and is positioned with the "eight" shaped inclined surface of the slot. At this time, the locking block is aligned with the slot of the fixed sleeve, and the auxiliary spring telescopic rod drives the locking block to be inserted into the slot, completing the axial locking of the sliding lock sleeve and the fixed sleeve. At the same time, the reset spring retraction rod is stretched and stored to ensure that the side slider position is fixed.

[0025] S2. Mold Closure and Casting: The die-casting machine drives the moving mold and the stationary mold to close and lock the mold, forming a closed molding cavity; molten aluminum is poured into the cavity and held under pressure to cool and form the product. The side slide block in the locked state has its end inclined pressing surface completely in contact with the inclined surface of the product, which can resist the filling pressure and prevent displacement, providing a stable foundation for subsequent positioning.

[0026] S3. Anti-sticking limit during initial mold opening: When the mold opens, the moving mold moves away from the stationary mold. During this stage, the side slider remains locked and the inclined pressing surface continuously applies a pressing force towards the moving mold to completely counteract the product's wrapping force on the stationary mold, forcing the product to move synchronously with the moving mold, thus achieving reliable separation between the product and the stationary mold and preventing the stationary mold from sticking abnormally from the root.

[0027] S4. Slider Unlocking and Retraction and Mechanism Reset: After the product is completely detached from the stationary mold, the external robot presses the inner push block, which compresses the reset spring and slides inward. Through the L-shaped guide plate and guide plate, the push rod is squeezed, which drives the locking block to exit the slot and completes the unlocking. The pre-stretched reset spring retracts and releases its elasticity, pulling the side slider outward to remove the product constraint and avoid the ejection path. Then the moving mold ejection rod ejects the product, and the robot completes the part removal. After the pressure on the inner push block is released, the reset spring drives the inner push block to reset, and the guide plate rebounds and resets under the action of the torsion spring, completing the mechanism reset for a single production cycle.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0029] This invention completely solves the problem of static mold sticking, significantly improving production stability and product yield. By creating a slot on the moving mold side and installing a side slider, the inclined pressing surface at the end of the side slider precisely conforms to the product's inclined surface during the mold closing and forming stage. In the initial mold opening stage, the side slider is kept in a stable locked state by a locking component. The inclined pressing surface forcibly presses and limits the formed product to the moving mold side, ensuring that the product moves synchronously with the moving mold during mold opening and smoothly separates from the static mold. This fundamentally avoids the problem of product sticking to the static mold, demolding failure, and product scrap caused by the small difference in the wrapping force between the moving and static molds, significantly improving the continuity of die-casting production and the product qualification rate.

[0030] This invention: It fully adapts to customer performance requirements without modifying the original product structure. The anti-sticking function of this invention is achieved entirely through the side slider structure on the moving mold side, without requiring any modification to the original demolding angle or overall structure of the product. It fully meets the stringent requirements of customers for product CAE modal analysis and structural performance, solving the core problem that conventional demolding angle adjustment solutions cannot be implemented, and eliminating the need for additional investment in product structure modification verification costs and mold opening costs.

[0031] This invention does not affect the internal molding quality of the product, simplifies the mold structure, and reduces production and maintenance costs. This invention eliminates the need for any ejection mechanism on the stationary mold side, does not change the original thickness of the stationary mold, and completely avoids the problems of reduced cylinder filling and poor molten metal filling effect caused by thickening the stationary mold, thus fully ensuring the internal molding quality of the product. At the same time, compared to solutions that add a stationary mold ejection system, it significantly simplifies the overall mold structure, reduces mold processing and manufacturing costs and subsequent maintenance difficulty, and can be directly adapted to existing conventional die-casting production lines without changing production equipment or adding production processes. The implementation threshold is extremely low, making it suitable for mass production and application.

[0032] This invention features an ingenious locking and unlocking structure with precise and controllable timing, adapting to continuous production cycles. The invention achieves stable locking of the side slider through a locking component, and rapid unlocking and automatic reset of the slider through an unlocking component in conjunction with a return spring retraction rod. The structure is logically clear and highly stable: during mold closing, the locking block engages with the slot to ensure stable locking of the side slider within the slot, guaranteeing effective limiting and pressing of the slider in the initial mold opening stage; after the product is completely detached from the stationary mold, pressing the inner push block drives the guide plate to press the shaft, causing the locking block to disengage from the slot and unlock the slider. The pull of the return spring retraction rod then quickly separates the side slider from the product, without affecting the subsequent ejection process of the moving mold; simultaneously, the cooperation of the one-way locking block and torsion spring enables automatic reset of the unlocking mechanism, perfectly adapting to continuous die-casting production cycles, offering convenient operation and simple maintenance.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention.

[0044] Please see Figures 1 to 9 This invention provides a technical solution: a die-casting mold with side sliders, including a stationary mold 1, a moving mold 2 abutting against the stationary mold 1, and an ejector rod on the moving mold 2. The prior art is not described here. At least three slots 3 are opened on the side of the moving mold 2. The width of the slots 3 can be adjusted according to the requirements. The inner wall of the slot 3 facing the inner cavity of the moving mold 2 is an "eight" shaped inclined surface. A side slider 4 corresponding to the size of the slot 3 is inserted into the slot 3. The side slider 4 facing the inner cavity of the moving mold 2 has an inclined surface 5 that fits the slot 3. The side slider 4 facing the inner cavity of the moving mold 2 has an inclined pressing surface 6 for fitting the inclined surface of the product, ensuring that the product formed after mold opening is stably fixed in the moving mold 2.

[0045] The side slider 4 is equipped with a locking element, which locks the side slider 4 into the slot 3.

[0046] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 9 As shown, the locking component includes a fixed sleeve 7, which is fixedly installed in the corresponding slot 3. The inner cavity of the fixed sleeve 7 has the same size to accommodate the sliding of the sliding lock sleeve 71 of the same size in the fixed sleeve 7, ensuring maintenance efficiency. The outer wall size of the fixed sleeve 7 is adjusted and adapted according to the size of the slot 3. The sliding lock sleeve 71 is slidably inserted into the inner wall of the fixed sleeve 7. The end of the sliding lock sleeve 71 facing the inner cavity of the moving mold 2 is fixedly connected to the side slider 4. Two locking blocks 72 are symmetrically inserted on the upper and lower sides of the inner wall of the sliding lock sleeve 71. Two auxiliary spring telescopic rods 73 arranged in a figure-eight shape are symmetrically hinged on the left and right sides of the locking blocks 72. The end of the auxiliary spring telescopic rod 73 away from the locking blocks 72 is hinged to the corresponding side of the inner wall of the sliding lock sleeve 71.

[0047] The locking block 72 abuts against the slot 74 opened inside the fixed sleeve 7 by the pulling force of the auxiliary spring telescopic rod 73, and the abutting end of the locking block 72 is embedded with a ball. By inserting the locking block 72 into the slot 74, the fixed sleeve 7 is locked in the sliding lock sleeve 71, and the side slider 4 is locked in the slot 3.

[0048] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 9 As shown, guide grooves 75 are provided on both the upper and lower sides of the sliding lock sleeve 71. A return spring retraction rod 76 is provided inside the sliding lock sleeve 71. One end of the return spring retraction rod 76 is fixedly connected to the side slider 4, and the other end passes through the corresponding guide groove 75 and is fixedly connected to the inner wall of the fixed sleeve 7. The return spring retraction rod 76 applies a pulling force to the side slider 4.

[0049] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 9 As shown, an unlocking component is also slidably disposed inside the sliding lock sleeve 71. The unlocking component includes an inner push block 8 that slides inside the sliding lock sleeve 71. A return spring 87 is fixedly connected between one end of the inner push block 8 and the side slider 4.

[0050] The inner push block 8 has U-shaped grooves 81 on both the upper and lower sides. Two symmetrically arranged L-shaped guide plates 82 are fixedly connected to the inner wall of the U-shaped grooves 81. A guide plate 83 is hinged to one end of each L-shaped guide plate 82, and a one-way locking block 86 is fixedly connected to the hinged end of the guide plate 83. A torsion spring 84 is installed between the guide plate 83 and the L-shaped guide plate 82, ensuring that the guide plate 83 forms an obtuse angle with the L-shaped guide plate 82 when no force is applied. The one-way locking block 86 at the end of the guide plate 83... The locking block 86 abuts against the L-shaped guide plate 82 via the torsion spring 84. The one-way locking block 86 ensures that when the guide plate 83 presses against the shaft 85, the guide plate 83 will not deflect relative to the L-shaped guide plate 82, thereby ensuring that the locking block 72 is stably pulled out from the slot 74. Similarly, the push block 8 is reset under the action of the reset spring 87. During this process, the shaft 85 will be passively pressed against the guide plate 83 to deflect, completing the reset of the push block 8 and the shaft 85, which is convenient for the next use.

[0051] The unlocking component also includes a shaft 85 fixed to the end of the locking block 72 away from the slot 74. The shaft 85 slides within the sliding sleeve 71 via the inner push block 8, causing the guide plate 83 and the L-shaped guide plate 82 to cooperate in pressing the shaft 85, thereby driving the locking block 72 to be pulled out of the slot 74. In conjunction with the return spring retraction rod 76, the side slider 4 slides within the slot 3, releasing the side slider 4 from contact with the product.

[0052] The method of use and advantages of this invention: When using this die-casting mold with a side slider, the working process is as follows:

[0053] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 9 As shown, when using the die-casting mold, the moving mold 2 and the stationary mold 1 are preheated first, and then a die-casting release agent is sprayed. Through an external robot arm, the sliding lock sleeve 71 is pushed to slide in the fixed sleeve 7, causing the locking block 72 in the sliding lock sleeve 71 to slide along the inner wall of the fixed sleeve 7. When the locking block 72 and the slot 74 are on the same vertical plane, the locking block 72 is pulled into the slot 74 by the auxiliary spring telescopic rod 73, locking the sliding lock sleeve 71 and the fixed sleeve 7. At this time, the side slider 4 corresponding to the end of the sliding lock sleeve 71 abuts against the "eight" shaped inclined surface of the inner wall of the slot 3, completing the fixation of the side slider 4.

[0054] Then, the moving mold 2 is connected to the stationary mold 1 through the die casting machine to complete the mold closing. The moving mold 2 and stationary mold 1 are locked after the mold closing by the die casting machine. Then, by injecting material into the injection port of the stationary mold 1, the material is formed in the cavity formed after the moving mold 2 and stationary mold 1 are connected. At this time, the inclined pressing surface 6 at the end of the side slider 4 is attached to the surface of the formed product.

[0055] After the product has cooled down, the moving mold 2 moves and separates from the stationary mold 1. At this time, the inclined pressing surface 6 at the end of the side slider 4 forces the product to be pressed and limited on the moving mold 2 side, so that the product can be smoothly separated from the stationary mold 1. This avoids the situation where the product is occasionally wrapped on the stationary mold 1 because the difference in the wrapping force between the moving mold 2 and the stationary mold 1 is not significant.

[0056] Then, the product is held by a material handling robot, and an external robot presses the corresponding inner push block 8 to compress the return spring 87. The inner push block 8 moves in the sliding lock sleeve 71, which drives the guide plate 83 to squeeze the shaft 85, thereby driving the locking block 72 to be pulled out from the slot 74. Since the contraction force of the return spring retraction rod 76 is much greater than the compression force of the return spring 87, the retraction of the return spring retraction rod 76 at this time causes the side slider 4 to slide in the slot 3 and separate from the product surface, releasing the side slider 4 from the product's limit. Then, the product is ejected by the product ejection rod in the moving mold 2.

[0057] At the same time, the sliding sleeve 71 slides inside the fixed sleeve 7, causing the shaft 85 to slide inside the L-shaped guide plate 82. When the sliding sleeve 71 is reset, the shaft 85 separates from the inside of the L-shaped guide plate 82; the pressure applied to the inner push block 8 is released, and the inner push block 8 is reset by the reset spring 87.

[0058] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
