Description

Technical Field

[0001] The invention relates to the technical field of die-casting dies, and in particular to an integrated die-casting die for a handbrake bracket of a new energy vehicle. Background Art

[0002] New energy vehicle handbrake bracket is a key component, such as Figure 1 As shown, the handbrake bracket 2 is composed of a handle 22 and a connector 21. The connector 21 is a nearly triangular shell structure, one side of the shell is provided with an open groove to form a single-side open accommodation space, and both sides of the shell are provided with mounting holes 211 for precise assembly with other components to achieve functional positioning. However, in the demolding stage after molding, the existing die-casting mold is prone to mold jamming due to the opening shape of the open groove of the connector 21 and the concave-convex structure formed by the mounting hole 211.

[0003] Taking Chinese patent announcement number CN216421036U as an example, although the ejection mechanism of the die-casting mold disclosed therein assists the entry and exit of the shaped parts through a two-way output mechanism, its ejection design still remains in the conventional category. For the handbrake bracket 2, this solution cannot adapt to the complex structure of the connector 21, and it can neither avoid the interference area of ​​the open groove nor deal with the jamming problem around the mounting hole 211. In fact, the demoulding mechanism of the traditional die-casting mold generally has the disadvantage of a single ejection method, which can only provide a simple vertical ejection action and cannot achieve orderly demoulding for the complex structure of the connector 21. This not only leads to low production efficiency, but also easily causes damage to the appearance or structural deformation of the handbrake bracket 2, and is completely unable to meet the needs of high-precision production of new energy vehicle parts. Therefore, the development of an integrated die-casting mold that can accurately cope with the complex structure of the connector 21 of the handbrake bracket 2 and achieve efficient demoulding has become a technical problem that the industry urgently needs to solve. Summary of the invention

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention, through the synergistic effect of the pre-separation of the two movable molds and the two-stage jacking assembly in the mold core, can achieve orderly demolding in stages for the complex structure of the connecting head of the handbrake bracket, and completely avoid the mold jamming problem caused by the single ejection method of the traditional mold; through the setting of the synchronous action of the mold core and the two movable molds, the number of independent driving devices required for demolding is reduced, the single-mold production cycle and the investment in production costs are significantly shortened, the automatic operation of the demolding process is realized, the need for manual disassembly and adjustment of the mold is reduced, the degree of automation of the production line is improved, the production efficiency is improved, and the safety risks of workers' operations are reduced.

[0016] 2. The present invention makes the sliding of the movable mold more stable and less prone to deviation or tilting by setting the second slide groove, thus ensuring a smooth demolding process.

[0017] 3.

At this time, the activation of the lifting mechanism only acts on the separation of the movable mold, and the two movable molds move away from each other in the horizontal direction, providing sufficient avoidance space for the demoulding of the handbrake bracket. It can reduce the lateral stress during the demoulding process, make the handbrake bracket more evenly stressed, reduce the risk of deformation or damage, and improve the product yield and quality stability.

[0030] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] like Figures 1 to 7 and Fig.12 As shown: an integrated die-casting mold for a handbrake bracket of a new energy vehicle, comprising a fixed mold 1, a lifting mechanism 12, a mold core 11 and two movable molds 18, wherein the mold core 11 can be slidably arranged in the fixed mold 1 along the vertical direction; the lifting mechanism 12 is arranged below the fixed mold 1 and is transmission-connected to the mold core 11; the two movable molds 18 are located at the top of the fixed mold 1 and can slide relatively in the horizontal direction; the mold core 11 comprises a cavity structure for forming the inner wall of the connector 21 of the handbrake bracket 2, and a two-stage lifting assembly 111 is arranged in the mold core 11; the fixed mold 1, The core mold 11 and the two movable molds 18 together constitute a complete molding cavity for the handle 22 of the handbrake bracket 2 and the connecting head 21; in the initial stage of the activation of the lifting mechanism 12, the core mold 11 will be driven to slide in the vertical direction, and at the same time, the lifting mechanism 12 will synchronously drive the two movable molds 18 to move away from each other in the horizontal direction to avoid the handbrake bracket 2; after the handbrake bracket 2 is initially ejected, the two-stage lifting component 111 is driven to separate the inner wall of the connecting head 21 from the core mold 11 through the two-stage lifting component 111, so that the handbrake bracket 2 is completely demolded.

[0032] The fixed mold 1, the core mold 11 and the two movable molds 18 are closed to form a complete cavity, wherein the core mold 11 is used to form the inner wall structure of the connector 21 of the handbrake bracket 2, and the core mold 11, the fixed mold 1 and the movable mold 18 cooperate to form the cavity of the outer wall of the connector 21 and the handle 22.

[0033] A sprue is provided on the fixed mold 1. Before die-casting, the mold core 11 needs to be located in the fixed mold 1. The two movable molds 18 are in a closed state and located on the fixed mold 1. The die-casting machine drives the molten metal to be pushed into the mold from the sprue to form a handbrake bracket 2. After the molding is completed, the handbrake bracket 2 needs to be demolded. At this time, the jacking mechanism 12 is started, and firstly, the mold core 11 is driven to move upward by the vertical lifting force. Since the mold core 11 is used to form the inner wall structure of the connecting head 21 of the handbrake bracket 2, the movement of the mold core 11 drives the formed handbrake bracket 2 to move synchronously with it; at the same time, the start of the jacking mechanism 12 also drives the movement of the two movable molds 18, so that the two movable molds 18 can slide relative to each other in the horizontal direction, so that the two movable molds 18 are away from each other, and the handbrake bracket 2 is actively avoided by the separation of the movable molds 18 to avoid the mold jamming during the demolding process.

[0034] Then the equipment enters the second-stage demoulding stage, by starting the second-stage lifting component 111, the inner wall of the connecting head 21 of the handbrake bracket 2 is separated from the mold core 11 through the second-stage lifting component 111, so that the handbrake bracket 2 is completely demoulded.

[0035] Through the synergistic effect of the pre-separation of the movable mold 18 and the two-stage jacking assembly 111, the complex structure of the connecting head 21 of the handbrake bracket 2 can be demoulded in stages in an orderly manner, completely avoiding the mold jamming problem caused by the single ejection method of the traditional mold; through the setting of the synchronous action of the mold core 11 and the two movable molds 18, the number of independent driving devices required for demoulding is reduced, which significantly shortens the single-mold production cycle and reduces the investment in production costs, realizes the automation of the demoulding process, reduces the need for manual disassembly and adjustment of the mold, improves the degree of automation of the production line, improves production efficiency, and reduces the safety risks of workers' operations.

[0036] The mold core 11 is responsible for the inner wall molding of the connector 21, and the fixed mold 1 and the movable mold 18 are responsible for the outer wall molding of the connector 21 of the handbrake bracket 2 and the handle 22, which effectively reduces the number of parting surfaces, improves molding accuracy, and meets the requirements of high-precision and high-reliability parts in the field of new energy vehicles. Through the reasonable mold structure setting, the fixed mold 1, the mold core 11 and the movable mold 18 each bear reasonable force distribution during the molding and demoulding process, reducing mold wear caused by forced demoulding, thereby extending the service life of the mold and reducing production costs.

[0037] like Figures 2 to 7 , Fig.11 and Fig.12As shown: the two-stage lifting assembly 111 includes a lifting rod 1111, a first limiting groove 1114 extending in the vertical direction is opened in the mold core 11, the lifting rod 1111 is sleeved in the first limiting groove 1114 and slidably cooperates with the first limiting groove 1114, a limiting ring 1113 is arranged on the lifting rod 1111, an elastic member 1112 is arranged between the limiting ring 1113 and the first limiting groove 1114, a wedge block 13 that can move in the horizontal direction is arranged at the bottom of the fixed mold 1, and the bottom of the lifting rod 1111 is slidably cooperated with the wedge block 13.

[0038] After the handbrake bracket 2 is initially ejected, demoulding enters the second stage of lifting. At this time, the wedge block 13 at the bottom of the fixed mold 1 will move in the horizontal direction, and the movement of the wedge block 13 will push the bottom of the lifting rod 1111, so that the lifting rod 1111 rises in the vertical direction in the first limiting groove 1114. Since the limiting ring 1113 is provided on the lifting rod 1111, and the elastic member 1112 cooperates with the first limiting groove 1114, so that the elastic member 1112 is stretched at this time, and the rise of the lifting rod 1111 further pushes the connector 21 of the handbrake bracket 2, so that the inner wall of the connector 21 is separated from the mold core 11, and finally the handbrake bracket 2 is completely demoulded. The setting of the elastic member 1112 ensures the buffering effect during the jacking process, avoiding damage or deformation of the handbrake bracket 2 due to excessive impact force. At the same time, after the wedge block 13 is reset, the jacking rod 1111 can return to the initial position through the contraction of the elastic member 1112, which is convenient for cooperation with the wedge block 13 during the next demoulding.

[0039] A two-stage lifting structure is adopted to ensure that the inner wall of the connector 21 of the handbrake bracket 2 can be smoothly separated from the mold core 11 after the initial demolding, avoiding product deformation or damage that may be caused by forced demolding at one time, and improving the stability and smoothness of demolding. The lifting rod 1111 is driven to rise vertically through the horizontal movement of the wedge block 13, so that the inner wall of the connector 21 is separated from the mold core 11, avoiding the high resistance caused by directly pulling out the handbrake bracket 2, reducing the mold jamming during the demolding process, and improving production efficiency. Through a reasonable demolding structure, the friction between the mold core 11 and the connector 21 of the handbrake bracket 2 is reduced, and the loss of the mold is reduced, thereby extending the service life of the mold, reducing maintenance costs, and improving the overall production economy.

[0040] like Figures 2 to 7 Fig.11 and Fig.12 As shown: the lifting mechanism 12 is provided with a support plate 121 that can slide in the vertical direction, the support plate 121 is provided with a first slide groove 1211 extending in the horizontal direction, the wedge block 13 is slidably arranged in the first slide groove 1211, and the bottom of the fixed mold 1 is fixedly connected with an inclined support rod 14, and the wedge block 13 is sleeved on the support rod 14 and slidably cooperates with the support rod 14.

[0041] Since the horizontal movement of the wedge block 13 has a limited driving distance for the lifting rod 1111, in order to further improve the driving efficiency of the wedge block 13, a support plate 121 that can slide in the vertical direction is provided on the lifting mechanism 12, and a first slide groove 1211 extending in the horizontal direction is provided on the support plate 121. The wedge block 13 is slidably arranged in the first slide groove 1211, and the wedge block 13 is also sleeved on the inclined support rod 14 fixed at the bottom of the fixed mold 1, and slidably cooperates with the support rod 14.

[0042] When the wedge block 13 moves horizontally, it will perform a compound movement along the tilt direction of the support rod 14 because it is guided by the support rod 14 at the same time, that is, it will generate a certain vertical component while moving in the horizontal direction. Since the wedge block 13 is sleeved on the support rod 14, and the support plate 121 can slide in the vertical direction, the synchronous movement of the support plate 121 further increases the movement range of the wedge block 13, thereby increasing the driving distance of the wedge block 13 on the lifting rod 1111, so that the lifting rod 1111 can rise more significantly, ensuring that the connector 21 of the handbrake bracket 2 is more thoroughly separated from the mold core 11. In addition, when the support plate 121 is reset, the wedge block 13 will also be reset, so that the lifting rod 1111 can return to the initial position by relying on the contraction of the elastic member 1112, and prepare for the next demolding.

[0043] Due to the compound movement of the wedge block 13, the demoulding force is more evenly distributed, reducing the problem of incomplete demoulding caused by insufficient driving force of the lifting rod 1111, thereby effectively reducing the mold jam phenomenon and improving production efficiency. Through the synchronous sliding of the support plate 121, the movement of the lifting rod 1111 is more stable, avoiding instantaneous strong lifting to damage the handbrake bracket 2, improving the yield rate and reducing the defective rate. The force on each component of the mold is more even, reducing local overload wear, extending the service life of the mold, and reducing maintenance and replacement costs.

[0044] like Figures 2 to 7 , Fig. 9 , Fig.10 and Fig.12 As shown: a second slide groove 15 extending in the horizontal direction is arranged on the side of the fixed mold 1, and a sliding rod 1811 extending in the vertical direction is arranged on the two movable molds 18. The sliding rods 1811 of the two movable molds 18 can be relatively slidably arranged on the second slide groove 15.

[0045] During the demoulding stage, after the lifting mechanism 12 is started, it first drives the core 11 of the mold 18 to move in the vertical direction, and at the same time drives the sliding rods 1811 of the two movable molds 18 to slide in the second slide groove 15. Due to the restraining effect of the sliding rods 1811 in the second slide groove 15, the sliding of the movable mold 18 is more stable and not prone to offset or tilt, ensuring a smooth demoulding process. Ensure that the two movable molds 18 are evenly stressed when sliding in the horizontal direction, avoid tilting or jamming caused by uneven stress, improve the stability and controllability of the movement of the movable mold 18, and thus improve the smoothness of demoulding.

[0046] When the handbrake bracket 2 is completely demoulded, the two movable molds 18 can return to the initial position along the second slide groove 15 through the reset of the jacking mechanism 12, so as to prepare for the next die-casting molding and ensure the smooth operation of the mold cycle.

[0047] like Figures 2 to 7 , Fig. 9 , Fig.10 and Fig.12 As shown: pulleys 1812 are provided at the bottom of the two sliding rods 1811, a fixed plate 122 that can slide in the vertical direction is provided on the lifting mechanism 12, and two mirror-symmetrical and inclined first slide rails 1221 are provided on the fixed plate 122, and the pulleys 1812 of the two movable molds 18 are slidably arranged on the two first slide rails 1221 respectively.

[0048] When the lifting mechanism 12 drives the fixed plate 122 to rise in the vertical direction, due to the inclined structure of the first slide rail 1221, the rise of the fixed plate 122 will guide the pulley 1812 through the first slide rail 1221, so that the pulley 1812 slides outward along the first slide rail 1221, thereby driving the two movable molds 18 to move away from each other in the horizontal direction, providing sufficient demolding space for the demolding of the handbrake bracket 2. When the handbrake bracket 2 is completely demolded, the fixed plate 122 descends when the lifting mechanism 12 is reset, and the pulley 1812 returns to the initial position along the inclined first slide rail 1221, driving the two movable molds 18 to move closer to each other in the horizontal direction, so that the mold is restored to its initial state, ready for the next die-casting.

[0049] Through the cooperation of the pulley 1812 and the inclined first slide rail 1221, the two movable molds 18 can move synchronously in the horizontal direction, ensuring balanced force on both sides, avoiding uneven demoulding due to different sliding speeds on one side, and improving molding accuracy and consistency. The rolling cooperation mode of the pulley 1812 and the first slide rail 1221 reduces friction resistance, making the movable mold 18 slide more smoothly in the horizontal direction, avoiding the jamming phenomenon caused by excessive friction, improving demoulding efficiency, helping to extend the service life of the mold and reduce maintenance costs.

[0050] like Fig. 9 , Fig.10 and Fig.12As shown, a second slide rail 1222 is disposed below the first slide rail 1221 and is connected to the first slide rail 1221 and extends in the vertical direction.

[0051] When the lifting mechanism 12 drives the fixed plate 122 to rise in the vertical direction, the pulley 1812 slides outward along the first slide rail 1221, so that the two movable molds 18 move away from each other in the horizontal direction. When the pulley 1812 reaches the end of the first slide rail 1221, it will continue to enter the connected second slide rail 1222. Since the second slide rail 1222 extends in the vertical direction, the pulley 1812 transitions from sliding in the horizontal direction to moving downward in the vertical direction. This transition process allows the two movable molds 18 to remain stable after being completely separated, and will not deviate or shake due to inertia or external force, ensuring smooth demoulding of the handbrake bracket 2.

[0052] After demolding is completed, the fixed plate 122 is reset along with the lifting mechanism 12, the pulley 1812 rises along the second slide rail 1222 and re-enters the first slide rail 1221, and then slides inward along the first slide rail 1221, so that the two movable molds 18 approach each other in the horizontal direction and return to the initial closed state, preparing for the next die-casting.

[0053] By smoothly switching between the first slide rail 1221 and the second slide rail 1222, the demoulding process of the movable mold 18 is more controlled, avoiding shaking or misalignment caused by inertia, thereby improving the overall stability of the mold and ensuring the accuracy and consistency of the handbrake bracket 2 after demoulding. The traditional one-way horizontal demoulding method may limit the demoulding space, causing the product to be squeezed or scratched during demoulding, while through the horizontal-vertical demoulding method, the two movable molds 18 can remain fixed after separation, avoiding accidental collision or friction, and improving the yield rate.

[0054] like Figures 2 to 7 , Fig. 9 , Fig.10 and Fig.12 As shown: the lifting mechanism 12 includes a plurality of first guide rods 123 extending in the vertical direction and being retractable. The plurality of first guide rods 123 all penetrate the bottom of the fixed mold 1 and slide with the fixed mold 1 . The mold core 11 is fixedly connected to the top of the plurality of first guide rods 123 .

[0055] When the lifting mechanism 12 is activated, the first guide rod 123 does not immediately drive the core 11 of the mold 18 to move, but leaves a certain margin so that the core 11 remains stationary in the initial stage. At this time, the activation of the lifting mechanism 12 only acts on the separation of the movable mold 18, and the two movable molds 18 move away from each other in the horizontal direction, providing sufficient avoidance space for the demoulding of the hand brake bracket 2.

[0056] When the first guide rod 123 shrinks to the limit state, the force of the lifting mechanism 12 is transmitted to the mold core 11 through the first guide rod 123, so that the mold core 11 rises in the vertical direction, driving the handbrake bracket 2 to be ejected synchronously. Since the two movable molds 18 have been completely separated before, the handbrake bracket 2 can be smoothly separated from the cavity, avoiding mold jamming or product deformation caused by interference during demolding. Finally, the handbrake bracket 2 is further acted upon by the second-stage lifting assembly 111 to achieve complete demolding.

[0057] By first separating the movable mold 18 in the above manner, and then driving the core 11 of the mold 18 to lift up by the first guide rod 123, the lateral stress during the demoulding process can be reduced, so that the handbrake bracket 2 is more evenly stressed, the risk of deformation or damage is reduced, and the yield rate and quality stability of the product are improved. Sufficient demoulding space is provided for the handbrake bracket 2 to avoid lateral extrusion or mold jamming of the product due to premature lifting of the core 11. The staged demoulding method is adopted to reduce the friction between the movable mold 18, the core 11 and the product, reduce the wear rate of the mold, and improve the durability of the mold, thereby extending the service life of the mold and reducing maintenance costs.

[0058] like Figures 2 to 7 , Fig. 9 , Fig.10 and Fig.12 As shown: a mounting seat 16 for supporting the handle 22 of the handbrake bracket 2 is arranged on the side of the fixed mold 1, and the lifting mechanism 12 also includes a lifting plate 1241 and two second guide rods 124 that can slide in the mounting seat 16, the second guide rods 124 are a retractable structure, and the lifting plate 1241 is fixedly connected to the top of the two second guide rods 124.

[0059] In the initial stage of the lifting mechanism 12 starting, the second guide rod 124 will not extend immediately, but leave a certain margin, so that the lifting plate 1241 temporarily remains stationary, thereby giving priority to completing the separation of the movable mold 18. When the movable mold 18 is completely separated, the second guide rod 124 shrinks to the limit, so that the lifting mechanism 12 can drive the lifting plate 1241 to rise through the second guide rod 124, and assist the handle 22 of the handbrake bracket 2 to be partially demoulded.

[0060] In the second-stage lifting stage, the lifting plate 1241 does not continue to rise, and only the second-stage lifting component 111 acts on the inner wall of the connector 21 to completely separate it from the mold core 11, thereby achieving complete demoulding.

[0061] Through the cooperation between the mounting seat 16 and the lifting plate 1241, the handle 22 of the handbrake bracket 2 can be provided with stable support, thereby avoiding tilting, deformation or breakage due to uneven force in the initial demoulding stage, thereby improving the yield and quality of the product.

[0062] like Figures 2 to 7 , Fig. 9 , Fig.10 and Fig.12 As shown: a plurality of third guide rods 17 extending in the vertical direction are arranged below the fixed mold 1, a mounting plate 125 which can slide with the third guide rods 17 is arranged at the bottom of the lifting mechanism 12, a driving shaft 1251 is arranged on the side of the mounting plate 125 away from the fixed mold 1, and the driving shaft 1251 is connected to the external driving device in a transmission manner.

[0063] When the external driving device is started, the driving shaft 1251 drives the mounting plate 125 to slide and rise along the third guide rod 17, thereby driving the lifting mechanism 12 to realize the demoulding action. The mounting plate 125 is guided by the third guide rod 17 to ensure a smooth and non-shaky lifting process. At the same time, the rising of the mounting plate 125 further promotes the movement of the first guide rod 123, the second guide rod 124 and the second-stage lifting assembly 111, so that the mold core 11 and the lifting plate 1241 are demoulded in a predetermined order, and finally the handbrake bracket 2 is completely demoulded.

[0064] The stable guiding effect of the third guide rod 17 avoids the mold core 11, the movable mold 18 and other structures from generating additional friction due to unstable movement during the demoulding process, thereby reducing the degree of wear of the mold, increasing the service life of the mold, and reducing maintenance costs. The drive shaft 1251 is connected to the external drive device in a transmission manner, which can realize automatic control, making the entire demoulding process more accurate and efficient, reducing manual intervention, improving the level of production automation, and meeting the needs of large-scale production.

[0065] like Figure 2 , Figure 4 , Figure 6 and Fig.12 As shown, the two movable molds 18 are respectively provided with a guide hole 1813 extending in the horizontal direction and a fourth guide rod 1814.

[0066] The fourth guide rod 1814 slides in the guide hole 1813 to provide precise constraints and guidance for the movement of the two movable molds 18, ensuring that the movable mold 18 slides smoothly along the specified trajectory without being offset or tilted due to external forces. This avoids mold jamming, mold wear, or poor product molding caused by deviation or tilt of the motion trajectory. It can effectively reduce unnecessary lateral friction, thereby reducing mold wear and increasing the service life of the mold.

[0067] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the protection scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
