Description

Technical Field

[0001] This application relates to the field of mold technology, specifically to a multi-directional core-pulling mechanism and mold. Background Technology

[0002] In the mold manufacturing industry, especially in injection molds and die-casting molds, the core-pulling mechanism is a key component. Its performance directly affects the molding quality, production efficiency, and demolding difficulty of the product. With the continuous upgrading of industrial products, the requirements for product shape and structure are becoming increasingly complex. Many products have complex structures such as undercuts and side holes, which places higher demands on mold core-pulling technology.

[0003] In related technologies, core-pulling mechanisms can typically only perform core-pulling actions in one or two specific directions. When a product has three or more undercuts in different directions, single-direction or double-direction core-pulling cannot smoothly remove the product from the mold, failing to meet the demolding requirements of complex undercut structures, resulting in difficulties in product demolding or damage. Utility Model Content

[0004] The purpose of this application is to provide a multi-directional core-pulling mechanism and mold to solve the problems of difficult demolding of multi-directional undercuts and easy product damage.

[0005] To achieve the objectives of this application, the following technical solution is provided:

[0006] In a first aspect, this application provides a multi-directional core-pulling mechanism for use in a mold, comprising:

[0007] First slide;

[0008] The upper template is provided with a first guide and a second guide, the first guide being slidably connected to the first slide block;

[0009] A first core block, a second core block, and a third core block form an inverted cavity. The first core block is fixed to the first slide block. The first core block is provided with a slidable second slide block. The second slide block is slidably connected to the second guide member. The second core block is slidably connected to the second slide block. The third core block is movably connected to the first slide block.

[0010] When the mold is opened, the second guide drives the second slide to move in the first direction, so that the second slide drives the second core block to disengage from the undercut in the second direction. Then, the first guide drives the first slide to move in the first direction, so that the first core block disengages from the undercut in the first direction, and the third core block disengages from the undercut in the third direction.

[0011] The first direction, the second direction, and the third direction intersect each other.

[0012] In one embodiment, the first guide member includes a first vertical section and a first inclined section connected together, the first inclined section being inclined relative to the vertical direction; the second guide member includes a second vertical section and a second inclined section connected together, the second inclined section being inclined relative to the vertical direction.

[0013] In the orthographic projection of the first direction, the second inclined segment is located above the first inclined segment.

[0014] In one embodiment, the first slide has a first through hole, the second slide has a second through hole, and when the second guide is inserted into the second through hole, the first vertical section is inserted into the first through hole;

[0015] When the second inclined section is inserted into the first through hole, the second guide separates from the second through hole.

[0016] In one embodiment, the first core block is provided with a mounting groove, and the second slide block is slidably disposed in the mounting groove. The bottom wall of the mounting groove is provided with a slot and a first sliding groove. The slot is for the second inclined section to be inserted, and the first sliding groove extends along the second direction. The second core block is provided with a first sliding part, and the first sliding part is disposed in the first sliding groove.

[0017] In one embodiment, the second slide block is provided with a guide protrusion, the second core block is provided with a guide groove, the guide protrusion is engaged in the guide groove, and both the guide protrusion and the guide groove are inclined relative to the first direction;

[0018] When the second guide drives the second slide to move in the first direction, the guide protrusion slides along the guide groove so that the second core block moves along the first slide groove to disengage from the overlock.

[0019] In one embodiment, the second slide block is provided with a first abutting surface, and the second core block is provided with a second abutting surface that connects with the guide groove. The first abutting surface and the second abutting surface are arranged opposite to each other in the first direction.

[0020] When the mold is closed, the first abutting surface abuts against the second abutting surface; when the mold is opened, there is a gap between the first abutting surface and the second abutting surface.

[0021] In one embodiment, the multi-directional core-pulling mechanism further includes a lower template and an insert, wherein the lower template is provided with a first slide rail extending along the first direction, and the first slide block is slidably disposed on the first slide rail;

[0022] The insert is provided with a second slide rail extending along the third direction, and the third core block is slidably disposed on the second slide rail.

[0023] In one embodiment, the first slide block is provided with a second slide groove extending in a vertical direction, the third core block is provided with a second sliding part, the second sliding part is disposed in the second slide groove, and the third core block is inclined relative to the vertical direction and the first direction.

[0024] In one embodiment, the second slide abuts against the second core block and the third core block at both ends in the second direction, and one end of the second slide in the first direction is used to abut against the overturned part.

[0025] Secondly, this application also provides a mold, including a multi-directional core-pulling mechanism as described in any one of the various embodiments of the first aspect.

[0026] Compared with the prior art, this application has at least the following beneficial effects:

[0027] 1. In this application, the first guide member and the second guide member respectively guide the movement of the first slide block and the second slide block, enabling the first core block, the second core block, and the third core block to perform core-pulling actions along the first direction, the second direction, and the third direction (intersecting in pairs). This multi-directional core-pulling method can accurately adapt to the molding requirements of products with complex undercut structures, ensuring that each undercut part of the product can smoothly detach from the mold, avoiding product damage or inability to demold due to a single core-pulling direction, and greatly improving the molding quality and demolding success rate of the product.

[0028] 2. In this application, during mold opening, the second guide component first drives the second slide block to disengage the second core block from the undercut along the second direction. Then, the first guide component drives the first slide block to disengage the first core block from the undercut along the first direction, while the third core block disengages from the mold along the third direction. This orderly multi-directional core-pulling process reduces demolding time, allowing the product to be removed from the mold more quickly, thereby improving the efficiency of the entire production cycle and reducing production costs.

[0029] 3. In this application, by adjusting the motion parameters of the first and second guide components, as well as the connection method and dimensions between each core block, the production of various products with different complexities and undercut directions can be adapted. This makes the mold more versatile and adaptable; one mold can be used to produce a variety of products with different structures, reducing the number and cost of mold development and improving mold utilization.

[0041] The following are specific embodiments of this application, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of this application. However, this application is not limited to these embodiments.

[0042] refer to Figures 1-5 This application provides a multi-directional core-pulling mechanism for use in a mold to form a product 100 with an undercut 110. The product 100 can be a charging port cover, a fuel tank cover, etc. The undercut 110 includes a first connecting part 111, a second connecting part 112, and a third connecting part 113 respectively in different directions.

[0043] The multi-directional core-pulling mechanism includes a first slide block 200, an upper template (not shown), and a first core block 410, a second core block 420, and a third core block 430 that form an inverted 110-shaped cavity.

[0044] The first slide block 200 serves as the mounting carrier for the first core block 410 and the third core block 430. During the mold opening process, it can move along the first direction X under the drive of the first guide member 310, thereby driving the first core block 410 to perform a core-pulling action along the first direction X, and also providing a basis for the movable connection of the third core block 430.

[0045] The upper template is provided with a first guide member 310 and a second guide member 320, and the first guide member 310 is slidably connected to the first slide block 200. The upper template is the fixed support part of the entire mechanism, providing the installation position for the first guide member 310 and the second guide member 320.

[0046] The first core block 410 is fixed to the first slide block 200. The first core block 410 has a slidable second slide block 440, which is slidably connected to the second guide member 320. The second core block 420 is slidably connected to the second slide block 440, and the third core block 430 is movably connected to the first slide block 200. The first core block 410, the second core block 420, and the third core block 430 together form the cavity of the inverted 110, which is a key component in forming the inverted 110 structure. When the mold opens, the first core block 410 moves along the first direction X with the first slide block 200, realizing its own core pulling in the first direction X. At the same time, the second slide block 440 provided on it provides a basis for the movement of the second core block 420. The first guide member 310 and the second guide member 320 respectively guide the movement direction of the first slide block 200 and the second slide block 440, ensuring that the core pulling action is carried out accurately in the predetermined direction, and ensuring the stability and accuracy of the movement of each component when the mold opens.

[0047] The first core block 410 is used to form the first connecting part 111 of the undercut 110, the second core block 420 is used to form the second connecting part 112 of the undercut 110, and the third core block 430 is used to form the third connecting part 113 of the undercut 110.

[0048] When the mold opens, the second guide 320 drives the second slide 440 to move along the first direction X, so that the second slide 440 drives the second core block 420 to disengage from the undercut 110 along the second direction Y. Then, the first guide 310 drives the first slide 200 to move along the first direction X, so that the first core block 410 disengages from the undercut 110 along the first direction X, and the third core block 430 disengages from the undercut 110 along the third direction Z. The first direction X, the second direction Y and the third direction Z intersect each other.

[0049] In this application, the first guide 310 and the second guide 320 guide the movement of the first slide 200 and the second slide 440, respectively, so that the first core block 410, the second core block 420 and the third core block 430 can perform core-pulling actions along the first direction X, the second direction Y and the third direction Z (intersecting in pairs). This multi-directional core-pulling method can accurately adapt to the molding requirements of the product 100 with a complex undercut 110 structure, ensuring that each undercut 110 part of the product 100 can be smoothly released from the mold, avoiding the problem of product 100 being damaged or unable to be demolded due to a single core-pulling direction, and greatly improving the molding quality and demolding success rate of the product 100.

[0050] When the mold opens, the second guide 320 first drives the second slide 440 to disengage the second core block 420 from the undercut 110 along the second direction Y. Then, the first guide 310 drives the first slide 200 to disengage the first core block 410 from the undercut 110 along the first direction X. At the same time, the third core block 430 disengages from the mold along the third direction Z. This orderly multi-directional core-pulling process reduces demolding time, allowing the product 100 to be removed from the mold more quickly, thereby improving the efficiency of the entire production cycle and reducing production costs.

[0051] The first guide member 310 includes a first vertical segment 311 and a first inclined segment 312 connected together, the first inclined segment 312 being inclined relative to the vertical direction; the second guide member 320 includes a second vertical segment 321 and a second inclined segment 322 connected together, the second inclined segment 322 being inclined relative to the vertical direction; in the orthographic projection of the first direction X, the second inclined segment 322 is located above the first inclined segment 312.

[0052] Specifically, during the mold opening process, the second inclined segment 322 of the second guide member 320 preferentially contacts the second slide block 440, driving the second slide block 440 to move along the first direction X, thereby driving the second core block 420 to complete the core-pulling action in the second direction Y. When the second slide block 440 moves to the end of the second inclined segment 322, the first inclined segment 312 of the first guide member 310 begins to contact the first slide block 200. At this time, the second guide member 320 disengages from the second slide block 440, and the first slide block 200 continues to move along the first direction X under the guidance of the first inclined segment 312, driving the first core block 410 to complete the core-pulling action. The staggered arrangement of the two inclined segments in the projection direction ensures that the driving action of the second guide member 320 takes precedence over that of the first guide member 310, avoiding motion interference.

[0053] This application uses a layered arrangement of inclined guide sections to enable the second slide 440 and the first slide 200 to be driven in a time-sharing manner. The second slide 440 completes the core pulling first before triggering the action of the first slide 200, eliminating motion interference when multiple slides are linked. This allows for orderly core pulling in three directions within a limited space, solving the problem of poor demolding caused by motion interference in traditional mechanisms.

[0054] The first slide block 200 has a first through hole 210, and the second slide block 440 has a second through hole 441. When the second guide member 320 is inserted into the second through hole 441, the first vertical segment 311 is inserted into the first through hole 210; when the second inclined segment 322 is inserted into the first through hole 210, the second guide member 320 is separated from the second through hole 441. Specifically, in the mold-closed state, the second vertical segment 321 of the second guide member 320 is inserted into the second through hole 441 of the second slide block 440, and at this time, the first vertical segment 311 of the first guide member 310 is inserted into the first through hole 210 of the first slide block 200, so that each slide block is in its initial positioning state. When the mold begins to open, the second inclined segment 322 of the second guide member 320 gradually enters the first through hole 210. At this time, the second guide member 320 disengages from the second through hole 441, and the second slide block 440 begins to slide along the first direction X under the guidance of the second inclined segment 322. This structure creates a time difference between the movement of the first slide 200 and the second slide 440. For example, the first slide 200 starts moving only after the second slide 440 has completed its predetermined stroke, thereby realizing multi-stage time-sharing core pulling action, effectively avoiding structural interference problems during multi-directional core pulling, and improving the success rate of demolding complex undercut 110.

[0055] refer to Figures 5-8The first core block 410 has a mounting groove 411, and the second slide block 440 is slidably disposed in the mounting groove 411. The bottom wall of the mounting groove 411 has a slot 412 and a first sliding groove 413. The slot 412 allows the second inclined segment 322 to be inserted, and the first sliding groove 413 extends along the second direction Y. The second core block 420 has a first sliding part 421 disposed in the first sliding groove 413. The mounting groove 411 is a recessed structure disposed inside the first core block 410 to accommodate the second slide block 440. Specifically, it can be implemented using a rectangular or U-shaped groove structure to limit the sliding path of the second slide block 440 and maintain motion stability. The slot 412 is an opening structure formed in the bottom wall of the mounting groove 411. Specifically, it can be implemented using an inclined groove matching the shape of the second inclined segment 322 to guide the insertion of the second inclined segment 322 and drive the second slide block 440 to slide during the mold opening process. The first slide groove 413 refers to a straight groove extending along the second direction Y, used to constrain the movement direction of the first sliding part 421, so that the second core block 420 disengages from the inverted buckle 110 along the second direction Y. The first sliding part 421 refers to a protruding structure provided on the second core block 420, used to be embedded in the first slide groove 413 and slide along its extension direction.

[0056] Specifically, when the mold opens, the second inclined segment 322 inserts into the slot 412, pushing the second slide block 440 to slide along the first direction X. Since the second slide block 440 is confined within the mounting groove 411, its movement trajectory is constrained by the side wall of the mounting groove 411. At the same time, the first sliding part 421 of the second core block 420 moves along the first slide groove 413, forcing the second core block 420 to disengage from the undercut 110 along the second direction Y. This application integrates the slot 412 and the first slide groove 413 into the bottom wall of the mounting groove 411 of the first core block 410, integrating the guiding functions of the second slide block 440 and the second core block 420 into the same component, which simplifies the structure and avoids the cumulative errors caused by the cooperation of multiple components.

[0057] The second slide block 440 is provided with a guide protrusion 442, and the second core block 420 is provided with a guide groove 422. The guide protrusion 442 is engaged in the guide groove 422, and both the guide protrusion 442 and the guide groove 422 are inclined relative to the first direction X. When the second guide member 320 drives the second slide block 440 to move along the first direction X, the guide protrusion 442 slides along the guide groove 422, so that the second core block 420 moves along the first slide groove 413 to disengage from the undercut 110. Specifically, during the mold opening process, when the second guide member 320 pushes the second slide block 440 to move along the first direction X, the guide protrusion 442 fixed to the second slide block 440 slides relative to the guide groove 422 of the second core block 420. Due to the inclined engagement relationship between the guide protrusion 442 and the guide groove 422, the second core block 420 generates a displacement component along the second direction Y under the constraint of the first slide groove 413, thereby realizing the separation from the cavity of the undercut 110. During this process, the driving force in the first direction X is decomposed into an effective demolding force in the second direction Y through the tilting sliding pair, while maintaining precise control of the motion trajectory.

[0058] This solution converts the driving force in one direction into multi-directional motion by using an inclined guide pair, which can complete the directional demolding of the second core block 420 without an additional power source, simplifying the mechanical structure and reducing the risk of motion interference.

[0059] The second slide block 440 is provided with a first abutting surface 443, and the second core block 420 is provided with a second abutting surface 423 that connects with the guide groove 422. The first abutting surface 443 and the second abutting surface 423 are arranged opposite to each other in the first direction X. When the mold is closed, the first abutting surface 443 and the second abutting surface 423 abut against each other. When the mold is opened, there is a gap between the first abutting surface 443 and the second abutting surface 423. Specifically, during the mold closing stage, the first abutting surface 443 of the second slide block 440 contacts the second abutting surface 423 of the second core block 420. At this time, the second core block 420 is pressed between the second slide block 440 and the undercut cavity 110 to ensure the positioning accuracy of each core block in the mold closing state. When the mold opens, the second guide 320 drives the second slide 440 to move along the first direction X. At this time, a gap is generated between the first contact surface 443 and the second contact surface 423. The second core block 420 disengages from the undercut 110 along the second direction Y under the cooperation of the guide groove 422 and the guide protrusion 442. The existence of the gap ensures that the movement of the second slide 440 and the second core block 420 does not interfere with each other, thereby realizing multi-directional sequential core pulling.

[0060] In this embodiment, the multi-directional core-pulling mechanism further includes a lower template 500 and an insert 600. The lower template 500 is provided with a first slide rail 510 extending along a first direction X, and a first slide block 200 is slidably disposed on the first slide rail 510. The insert 600 is provided with a second slide rail 610 extending along a third direction Z, and a third core block 430 is slidably disposed on the second slide rail 610. Specifically, during the mold opening process, the first slide block 200 slides along the extension direction of the first slide rail 510, causing the first core block 410 to exit the first connecting portion 111 of the undercut 110 along the first direction X. At the same time, the third core block 430 is constrained by the second slide rail 610 and slides along the third direction Z to disengage from the third connecting portion 113 of the undercut 110. The extension directions of the first slide rail 510 and the second slide rail 610 are not parallel to each other, so that the movement trajectories of the first core block 410 and the third core block 430 form an angle in space. By utilizing the template's own structure to provide a guiding function, no additional driving device is required, simplifying the internal spatial layout of the mold.

[0061] The first slide block 200 has a second groove 220 extending vertically, and the third core block 430 has a second sliding part 431 located in the second groove 220. The third direction Z is inclined relative to the vertical direction and the first direction X. The second groove 220 is an elongated groove on the side wall or top of the first slide block 200, with its extension axis parallel to the vertical direction. It can be implemented using a T-groove or dovetail groove structure, and is used to limit the movement trajectory of the third core block 430. The second sliding part 431 is a protrusion on the side wall of the third core block 430, which can be implemented using a slider or guide pin. Its cross-sectional shape matches the second groove 220, and it forms a sliding pair in the vertical plane. The inclination in the third direction Z means that the core-pulling trajectory of the third core block 430 forms an angle with the vertical direction.

[0062] Specifically, when the first slide block 200 moves along the first direction X during the mold opening process, the cooperation between the second slide groove 220 and the second sliding part 431 guides the third core block 430 to generate a compound motion. Due to the vertical extension characteristic of the second slide groove 220, the displacement component of the third core block 430 in the vertical plane is achieved by the sliding of the second sliding part 431 within the second slide groove 220; at the same time, the tilt angle of the third direction Z relative to the first direction X and the vertical direction causes the third core block 430 to generate a trajectory along the second slide rail 610 when it disengages from the undercut 110, thereby improving the stability of the movement of the third core block 430.

[0063] In this embodiment, the second slide block 440 abuts against the second core block 420 and the third core block 430 at both ends in the second direction Y, and the second slide block 440 at one end in the first direction X is used to abut against the undercut 110. Specifically, during the mold opening process, the second slide block 440 is driven by the second guide member 320 to move along the first direction X, and its end in the second direction Y pushes the second core block 420 to disengage from the undercut 110 along the second direction Y. The abutment relationship between the second slide block 440 at one end in the first direction X and the undercut 110 provides positioning support when the mold is closed, ensuring the stability of the undercut 110 structure during the molding process.

[0064] This application also provides a mold, including a multi-directional core-pulling mechanism, which comprises a first slide block 200, an upper template, a first core block 410, a second core block 420, and a third core block 430. The multi-directional core-pulling mechanism refers to a mechanism comprising three core block assemblies capable of moving in different directions. Specifically, it can be implemented using a mechanical linkage structure where the slide block and guide members cooperate, achieving multi-directional core-pulling action through staged driving of different guide members.

[0065] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application 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 indicator will also change accordingly.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0067] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0068] Furthermore, the technical solutions of the various embodiments of this application can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this application.
