Description

Technical Field

[0001] This application relates to the field of semi-solid die casting technology, and more specifically, to a semi-solid die casting mold for thin-walled metal parts. Background Technology

[0002] Semi-solid die casting is a process that uses die casting molds to rapidly shape semi-solid materials with a certain degree of fluidity. The principle involves injecting high-temperature semi-solid material into the mold cavity, allowing the material to fully fill the cavity. After cooling, the material maintains a fixed shape, thus quickly forming the desired product. Currently, semi-solid die casting is widely used in the production of thin-walled metal parts.

[0003] Die-casting molds typically have a discharge channel to remove excess material. Adjusting the size of the discharge channel regulates the material flow rate within the mold, ensuring complete filling of the mold cavity and improving product yield. Currently, the discharge channel opening can be enlarged by grinding or reduced by spot welding. However, both methods require stopping the die-casting equipment. In situations with limited space, disassembling the mold and moving the corresponding components to the designated location for grinding or spot welding can be time-consuming. Furthermore, each adjustment necessitates reassembly and verification, requiring repeated adjustments as needed. This results in lengthy mold setup and low efficiency. Utility Model Content

[0004] In view of this, this application provides a semi-solid die-casting mold for thin-walled metal parts, which can quickly adjust the size of the discharge channel to improve the efficiency of debugging operations of the semi-solid die-casting mold for thin-walled metal parts.

[0005] This application provides a semi-solid die-casting mold for thin-walled metal parts. The mold includes a mold body with a cavity inside. The mold body has multiple discharge channels communicating with the cavity along a first direction, and these channels are parallel to each other. The mold body also has multiple sliding holes communicating with each discharge channel along a second direction, which intersects the first direction. The mold further includes multiple stop members, multiple driving members, and multiple adjusting members corresponding to each discharge channel. Each stop member is slidably disposed in a sliding hole along the second direction, and at least a portion of the stop member can enter the corresponding discharge channel. A driving member is movably disposed on the mold body and movably connected to the stop member. Each adjusting member is movably connected to the corresponding driving member. Each adjusting member is configured to drive the corresponding driving member to reciprocate and move the corresponding stop member in the corresponding sliding hole, thereby adjusting the length of the portion of the stop member entering the corresponding discharge channel. At least a portion of each adjusting member is located outside the mold body.

[0006] During die casting, after the material flows into and fills the mold cavity, excess material overflows through the discharge channel. An adjusting component moves the driving component, causing it to move the stop component closer to or further away from the discharge channel. This increases or decreases the length of the stop component's entry into the discharge channel, blocking material flow and thus adjusting the material's flow velocity within the mold cavity. By positioning at least a portion of the adjusting component outside the mold body, the component can be operated without disassembling or removing the mold body, allowing for quick adjustment of the stop component's position. This reduces the time required for disassembling and assembling the mold body, thereby reducing the time needed for debugging semi-solid die casting molds for thin-walled metal parts and improving the efficiency of mold debugging operations.

[0007] In some embodiments of this application, the drive member is configured to provide a retaining force inclined in a second direction to the stop member, so that the stop member enters or moves away from the discharge channel in the second direction.

[0008] When the adjusting component moves the driving component relative to the mold body, the force of the driving component against the stop component has a component in the second direction, which allows the stop component to move along the second direction, thereby adjusting the length of the stop component entering the discharge channel.

[0009] In some embodiments of this application, the driving member has a driving surface, and the stop member has an abutting surface that abuts against the driving surface. The driving surface is configured to abut against the abutting surface when the driving member moves in the positive direction of a third direction. The driving surface and / or the abutting surface are inclined relative to the second direction.

[0010] When the adjusting member moves the driving member in the positive direction of the third direction, the driving surface pushes against the abutting surface. The driving surface has a supporting force that is inclined relative to the second direction on the abutting surface. The component of the supporting force in the second direction can make the material stopper move in the second direction, so as to achieve the effect of adjusting the length of the material stopper entering the discharge channel.

[0011] In some embodiments of this application, the drive member has an inclined portion at one end near the stop member that is inclined in a second direction. The stop member has a mating hole, and the inclined portion is inserted into the mating hole and abuts against the inner wall of the mating hole to provide a supporting force for the stop member.

[0012] When the driving component moves, the inner wall of the mating hole abuts against the inclined part, so that the inclined part generates a supporting force on the inner wall of the mating hole inclined in the second direction.

[0013] In some embodiments of this application, the adjusting member includes an adjusting screw, which is rotatably connected to the mold body and threadedly connected to the driving member, with at least a portion of the adjusting screw located outside the mold body.

[0014] By setting the axis of the adjusting screw along a third direction, the driving component can be moved along the third direction when the adjusting screw is rotated.

[0015] In some embodiments of this application, the adjusting member further includes a clamping screw threadedly connected to the mold body, the clamping screw being configured to clamp the driving member along the axial direction of the adjusting screw, and at least a portion of the clamping screw being located outside the mold body.

[0016] After the position of the stopper is adjusted, rotate the clamping screw to press against the drive component. This causes the inner wall of the threaded hole on the drive component that mates with the adjusting screw to press against the external thread on the adjusting screw. This fixes the adjusting screw relative to the drive component, thereby keeping the position of the drive component fixed and thus keeping the position of the stopper fixed.

[0017] In some embodiments of this application, the adjusting member further includes a mounting block and a limiting head. The mounting block is connected to the mold body, and the limiting head is connected to the adjusting screw. The mounting block has a through-hole along a third direction, and the adjusting screw is inserted into the rotating hole. The adjusting screw can slide relative to the inner wall of the rotating hole along the third direction and can rotate relative to the inner wall of the rotating hole about its own axis. The mounting block has a tightening screw hole, and the tightening screw is threadedly engaged with the tightening screw hole. The limiting head is configured to abut against the side of the mounting block opposite to the driving member along the third direction.

[0018] When the tightening screw presses against the drive component, the limiting head abuts against the mounting block, thereby fixing the drive component relative to the mounting block. Rotating the adjusting screw adjusts the distance between the limiting head and the drive component, thus adjusting the distance between the drive component and the mounting block when the limiting head is in contact with the mounting block, achieving the effect of adjusting the position of the drive component.

[0019] In some embodiments of this application, the driving member can reciprocate along a third direction; the mold body is provided with a constraint part, and the driving member is provided with a mating part that cooperates with the constraint part, and the constraint part is configured to constrain the position of the mating part in the third direction.

[0020] The mating part cooperates with the constraint part, and the constraint part can constrain the position of the mating part, thereby constraining the position of the driving part relative to the stop part in a third direction, so that the driving part and the stop part always maintain a movable connection, which can reduce the risk of the stop part disengaging from the driving part during the movement of the driving part.

[0021] In some embodiments of this application, the drive member is configured to move the stop member in the forward direction along the second direction; the semi-solid die-casting mold for thin-walled metal parts further includes an elastic member that connects the stop member and the mold body, and the elastic member is configured to provide an elastic force to the stop member that causes the stop member to move in the reverse direction along the second direction.

[0022] The driving component is used to drive the stop component to move forward along the second direction, and the elastic component is used to cause the stop component to move in the opposite direction along the second direction, thereby allowing precise adjustment of the length of the stop component entering the discharge channel portion. In some embodiments of this application, the semi-solid die-casting mold for thin-walled metal parts further includes a locking device, which is disposed on the mold body and configured to fix the stop component, with at least a portion of the locking device located outside the mold body.

[0023] Once the position of the stop component is adjusted, it can be fixed with fasteners to keep its position relative to the mold body. Attached Figure Description

[0031] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0033] The term “and / or” as used herein includes any and all combinations of one or more of the related listed items.

[0034] Furthermore, the terms “first,” “second,” “third,” etc., are used for descriptive purposes only and should not be interpreted as indicating or implying relative importance.

[0035] This application provides a semi-solid die-casting mold for thin-walled metal parts. The mold includes a mold body with a cavity inside. The mold body has multiple discharge channels communicating with the cavity along a first direction, and these discharge channels are parallel to each other. The mold body also has multiple sliding holes along a second direction, each corresponding to one of the discharge channels, intersecting the first direction. The mold further includes multiple stop members, multiple driving members, and multiple adjusting members, each corresponding to one of the discharge channels. Each stop member is slidably disposed in a sliding hole along the second direction, and at least a portion of the stop member can enter the corresponding discharge channel. A driving member is movably disposed on the mold body and movably connected to the stop member. Each adjusting member is movably connected to the corresponding driving member. Each adjusting member is configured to drive the corresponding driving member to reciprocate and move the corresponding stop member in the corresponding sliding hole, thereby adjusting the length of the portion of the stop member entering the corresponding discharge channel. At least a portion of each adjusting member is located outside the mold body.

[0036] During die casting, after the material flows into and fills the mold cavity, excess material overflows through the discharge channel. An adjusting component moves the driving component, causing it to move the stop component closer to or further away from the discharge channel. This increases or decreases the length of the discharge channel portion within the stop component. The portion of the stop component entering the discharge channel blocks the material, thereby adjusting the flow speed of the material within the mold cavity at the discharge channel. By positioning at least a portion of the adjusting component outside the mold body, the component can be operated without disassembling or removing the mold body, allowing for quick adjustment of the stop component's position. This reduces the time spent disassembling and assembling the mold body, thus reducing the time required for debugging semi-solid die casting molds for thin-walled metal parts and improving the efficiency of mold debugging operations.

[0037] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0038] Reference Figure 1 and Figure 2 This application provides a semi-solid die-casting mold 1000 for thin-walled metal parts. The semi-solid die-casting mold 1000 includes a mold body 100, and the interior of the mold body 100 is provided with a mold cavity 121. It is understood that the mold body 100 includes a fixed mold 11 and a movable mold 12 slidably connected to the fixed mold 11. At least one of the fixed mold 11 and the movable mold 12 is provided with a mold cavity 121, and after the movable mold 12 and the fixed mold 11 are closed, the mold cavity 121 forms a relatively closed space. After the semi-solid material flows and fills the mold cavity 121 and cools and solidifies, the material can form a product of the corresponding shape.

[0039] For example, the fixed mold 11 is provided with an injection hole 111; the moving mold 12 includes a mold base 122 and a mold core 123, with the mold base 122 slidably connected to the fixed mold 11. The mold base 122 has a mounting groove 1221 on the side facing the fixed mold 11, and the mold core 123 is embedded in the mounting groove 1221 and fixedly connected to the mold base 122; the mold core 123 has a mold cavity 121 on the side facing the fixed mold 11. It can be understood that the mold cavity 121 is open towards the fixed mold 11, and when the mold base 122 moves towards the fixed mold 11, the side of the mold core 123 facing the fixed mold 11 can abut against the fixed mold 11, so that the fixed mold 11 blocks the opening of the mold cavity 121 and makes the injection hole 111 communicate with the mold cavity 121. After the semi-solid material is injected into the mold cavity 121 through the injection hole 111, the material flows in the mold cavity 121 and fills the mold cavity 121, thus forming a product corresponding to the shape of the mold cavity 121.

[0040] In some embodiments, the mold core 123 is provided with a discharge channel 1231 along the first direction X, and the discharge channel 1231 communicates with the mold cavity 121. In some embodiments, the discharge channel 1231 is groove-shaped and opens toward the fixed mold 11. When the fixed mold 11 abuts against the mold core 123, the fixed mold 11 can block the opening on the corresponding side of the discharge channel 1231, so that the discharge channel 1231 is hole-shaped and extends along the first direction X. In other embodiments, the discharge channel 1231 can also be formed on the fixed mold 11, as long as the material in the mold cavity 121 can overflow into the discharge channel 1231.

[0041] Excess material in the mold cavity 121 can overflow through the discharge channel 1231. The size of the discharge channel 1231 affects the flow rate of the material in the mold cavity 121, and thus affects the filling state of the material in the mold cavity 121. Specifically, when the flow rate of the material in the discharge channel 1231 is slow, the material is prone to accumulate in the discharge channel 1231 and block the discharge channel 1231, resulting in poor material flow in the mold cavity 121. This makes it difficult for the material to fully fill the mold cavity 121, resulting in material shortage defects in the molded product. When the flow rate of the material in the discharge channel 1231 is fast, the material is more likely to overflow from the discharge channel 1231, making it difficult for the material to flow to the parts of the mold cavity 121 away from the discharge channel 1231. This results in insufficient material, making it difficult for the material to fully fill the mold cavity 121, resulting in material shortage and cracking defects in the molded product. Therefore, the flow rate of the material in the mold cavity 121 at the discharge channel 1231 should not be too fast or too slow. When the material has a suitable flow rate at the discharge channel 1231, the risk of defects such as cracking or material shortage in the molded product can be reduced, thereby improving the product yield.

[0042] Reference Figure 2 and Figure 3In some embodiments, the mold core 123 is provided with a sliding hole 1232 communicating with the discharge channel 1231 along the second direction Z, and the second direction Z intersects the first direction X. In some embodiments, the second direction Z is perpendicular to the first direction X, and the sliding hole 1232 is formed through the mold core 123 along the second direction Z. The semi-solid die-casting mold 1000 for thin-walled metal parts also includes a stop member 200, which is slidably disposed in the sliding hole 1232 along the second direction Z, and at least a portion of the stop member 200 can enter the discharge channel 1231.

[0043] The portion of the baffle 200 that enters the discharge channel 1231 can block the material. It can be understood that the greater the length of the portion of the baffle 200 entering the discharge channel 1231, the more significant the blocking effect of the baffle 200 on the material within the discharge channel 1231. The length of the portion of the baffle 200 entering the discharge channel 1231 can be adjusted by adjusting the position of the baffle 200 along the second direction Z relative to the mold body 100. When the length of the baffle 200 entering the discharge channel 1231 is large, the flow velocity of the material in the discharge channel 1231 is slower; when the length of the baffle 200 entering the discharge channel 1231 is small, the flow velocity of the material in the discharge channel 1231 is faster.

[0044] Therefore, by adjusting the position of the stopper 200, the flow rate of the material in the discharge channel 1231 can be adjusted, ensuring a suitable flow rate. This allows the material to fill the mold cavity 121 uniformly and fully, reducing the probability of defects such as cracking or material shortage in the molded product and thus improving the yield of die-cast products. In essence, by observing the state of the product after each molding process and continuously adjusting the position of the stopper 200 relative to the mold core 123 until the product's shape is satisfactory, the adjustment of the stopper 200 is complete, thereby improving the yield of subsequent molded products.

[0045] In some embodiments, multiple discharge channels 1231 are provided, and the multiple discharge channels 1231 are parallel to each other; multiple sliding holes 1232 and multiple baffles 200 are correspondingly provided, one sliding hole 1232 corresponds to one discharge channel 1231 and communicates with the corresponding discharge channel 1231, and one baffle 200 corresponds to one discharge channel 1231. Each baffle 200 can adjust the flow speed of the material at the corresponding discharge channel 1231. By providing multiple discharge channels 1231 and multiple baffles 200, the flow speed of the material at each discharge channel 1231 can be adjusted respectively, thereby facilitating the adjustment of the flow speed of the material at various points in the mold cavity 121.

[0046] Reference Figure 1 and Figure 3In some embodiments, the semi-solid die-casting mold 1000 for thin-walled metal parts further includes a plurality of driving members 300 and a plurality of adjusting members 400, with one driving member 300 corresponding to one adjusting member 400, and one driving member 300 corresponding to one stop member 200. The driving members 300 are movably disposed on the mold body 100, and the adjusting members 400 connect the corresponding driving member 300 to the mold body 100. The adjusting member 400 is configured to drive the corresponding driving member 300 to reciprocate, causing the driving member 300 to drive the corresponding stop member 200 to slide in the corresponding sliding hole 1232. (Refer to...) Figure 3 and Figure 4 In some embodiments, the drive member 300 is configured to provide a retaining force to the stop member 200 inclined in the second direction Z, so that the stop member 200 enters or moves away from the discharge channel 1231 in the second direction Z.

[0047] In some embodiments, the drive member 300 has a drive surface 31, and the stop member 200 has an abutment surface 21 that abuts against the drive surface 31. The drive surface 31 is configured to abut against the abutment surface 21 when the drive member 300 moves in the positive direction of a third direction Y, so that the stop member 200 enters or moves away from the discharge channel 1231 in the positive direction of a second direction Z. In some embodiments, the third direction Y intersects the second direction Z, and the drive surface 31 and / or the abutment surface 21 are inclined relative to the second direction Z. Exemplarily, the drive surface 31 and the abutment surface 21 are parallel to each other and both are inclined relative to the second direction Z; the third direction Y is perpendicular to the second direction Z and parallel to the first direction X.

[0048] In some embodiments, the stop member 200 is provided with a mating hole 23 extending through the material in the third direction Y, and the drive member 300 is generally rod-shaped extending in the third direction Y. An inclined portion 33 is provided at one end of the drive member 300 near the stop member 200, and the inclined portion 33 is inclined relative to the second direction Z. For ease of description, the end of the stop member 200 inserted into the discharge channel 1231 is defined as the stop portion 24. Along the positive direction of the third direction Y, the distance between the inclined portion 33 and the stop portion 24 gradually increases along the second direction Z. The inclined portion 33 is inserted into the mating hole 23, and the inner end walls of both ends of the mating hole 23 along the second direction Z are respectively abutted against the side walls of the inclined portion 33. It can be understood that the side wall of the inclined portion 33 along the second direction Z near the stop portion 24 forms a driving surface 31, and the inner end wall of the mating hole 23 along the second direction Z and near the stop portion 24 forms an abutment surface 21.

[0049] In some embodiments, the drive member 300 is provided with a pushing surface 32, and the stop member 200 is provided with a receiving surface 22 that abuts against the pushing surface 32. The receiving surface 22 is configured to push against the receiving surface 22 when the drive member 300 moves in the opposite direction of the third direction Y, so that the stop member 200 moves in the opposite direction of the second direction Z; the pushing surface 32 and / or the receiving surface 22 are inclined relative to the second direction Z. Exemplarily, the pushing surface 32 and the receiving surface 22 are parallel to each other and both are inclined relative to the second direction Z. It is understood that the pushing surface 32 is formed on the side of the inclined portion 33 along the second direction Z and away from the stop portion 24, and the receiving surface 22 is formed on the inner end wall of the mating hole 23 at the end along the second direction Z and away from the stop portion 24.

[0050] When the driving member 300 moves in the positive direction of the third direction Y, the driving surface 31 pushes against the abutting surface 21. The driving surface 31 has a supporting force on the abutting surface 21 that is inclined relative to the second direction Z. The supporting force has a positive component in the second direction Z, which causes the material stop 200 to move in the positive direction of the second direction Z, and causes the material stop 24 to move toward the interior of the discharge channel 1231. Similarly, when the driving member 300 moves in the reverse direction of the third direction Y, the pushing surface 32 pushes against the receiving surface 22, which causes the material stop 200 to move in the reverse direction of the second direction Z, and causes the material stop 24 to move away from the discharge channel 1231.

[0051] In some embodiments, one of the driving surface 31 and the abutting surface 21 may be parallel to the second direction Z, and the other of the driving surface 31 and the abutting surface 21 may be inclined relative to the second direction Z. In some other embodiments, one of the pushing surface 32 and the receiving surface 22 may be parallel to the second direction Z, and the other of the pushing surface 32 and the receiving surface 22 may be inclined relative to the second direction Z.

[0052] Reference Figure 1 and Figure 3At least a portion of the adjusting member 400 is located outside the mold body 100. It is understood that the fact that at least a portion of the adjusting member 400 is located outside the moving mold 12 allows the adjusting member 400 to be operated to adjust the position of the stop member 200 without disassembling the moving mold 12. By positioning at least a portion of the adjusting member 400 outside the mold body 100, the adjusting member 400 can be operated to quickly adjust the position of the stop member 200 without disassembling or removing the mold body 100, reducing the time required for disassembling and assembling the mold body 100. This reduces the time required for debugging the semi-solid die-casting mold 1000 for thin-walled metal parts, thereby improving the efficiency of the debugging operation of the semi-solid die-casting mold 1000 for thin-walled metal parts. The phrase "located outside the mold body 100" can be understood as at least a portion of the adjusting member 400 protruding from the surface of the mold body 100, or it can be understood as at least a portion of the adjusting member 400 being hidden in a groove or hole on the mold body 100. As long as the adjusting member 400 can be touched and operated by hand or by tool without disassembling the fixed mold 11 or the moving mold 12 of the die-casting mold.

[0053] In some embodiments, the mold base 122 has a fixing groove 1222 on the side facing the fixed mold 11. The fixing groove 1222 is provided through the mold along the third direction Y and communicates with the mounting groove 1221. The bottom of the fixing groove 1222 has a sliding groove 1223 along the third direction Y. The mold core 123 has a connecting hole 1233 along the third direction Y. The connecting hole 1233 communicates with the sliding hole 1232 and is aligned with the sliding groove 1223 along the third direction Y. The driving member 300 is slidably disposed in the sliding groove 1223 along the third direction Y, and one end of the driving member 300 is inserted into the connecting hole 1233 and cooperates with the stop member 200. In some embodiments, the moving mold 12 further includes a fixing block 124, which is embedded in the fixing groove 1222 and abuts against the bottom of the fixing groove 1222. The fixing block 124 is fixedly connected to the mold base 122 and can constrain the driving member 300 in the sliding groove 1223.

[0054] In some embodiments, the adjusting member 400 includes an adjusting screw 41, a clamping screw 42, a mounting block 43, and a limiting head 44. The mounting block 43 and the fixing block 124 are sequentially arranged along the third direction Y, and the mounting block 43 is fixedly connected to the outer wall of the mold base 122. The mounting block 43 is provided with a rotating hole 431 and a clamping screw hole 432 through it along the third direction Y. The driving member 300 is provided with an adjusting screw hole 35; the adjusting screw 41 is inserted through the rotating hole 431 and threadedly engaged with the adjusting screw hole 35; the inner diameter of the rotating hole 431 is larger than the major diameter of the adjusting screw 41, so that the adjusting screw 41 can rotate about its own axis and slide along the third direction Y. The clamping screw 42 is threaded into the clamping screw hole 432. The clamping screw 42 is configured to clamp the drive member 300 along the axial direction of the adjusting screw 41. It can be understood that the end of the clamping screw 42 away from the drive member 300 protrudes from the clamping screw 42 and is located on the side of the mounting block 43 away from the drive member 300 along the third direction Y. The limiting head 44 is located on the side of the mounting block 43 away from the drive member 300 along the third direction Y and is connected to the adjusting screw 41.

[0055] Rotating the adjusting screw 41 increases the distance between the limiting head 44 and the driving member 300. Then, rotating the clamping screw 42 causes the driving member 300 to move in the positive direction of the third direction (Y). After the limiting head 44 abuts against the mounting block 43, the clamping screw 42 clamps against the driving member 300, thus fixing the driving member 300. Reverse rotation of the clamping screw 42 disengages it from the driving member 300. Then, reverse rotation of the adjusting screw 41 decreases the distance between the limiting head 44 and the driving member 300, causing the driving member 300 to move in the negative direction of the third direction (Y). Finally, rotating the adjusting screw 41 again clamps against the driving member 300, thus fixing the driving member 300.

[0056] In other embodiments, a retaining ring can be provided on the adjusting screw 41, so that the retaining ring and the limiting head 44 respectively abut against the two sides of the mounting block 43 along the third direction Y, so as to restrict the sliding of the adjusting screw 41 in the third direction Y, so that the adjusting screw 41 can only rotate around its own axis. At this time, rotating the adjusting screw 41 can adjust the position of the driving member 300.

[0057] In other embodiments, the mounting block 43 may be omitted, and both the adjusting screw 41 and the clamping screw 42 are provided on the mold base 122 or the fixing block 124. Exemplarily, the mounting block 43 may be part of the mold base 122, such that both the adjusting screw 41 and the clamping screw 42 are connected to the mold base 122.

[0058] Reference Figure 3In some embodiments, the moving mold 12 is provided with a constraint portion 126, and the driving member 300 is provided with a mating portion 34 that cooperates with the constraint portion 126. The constraint portion 126 is configured to constrain the position of the mating portion 34 in the third direction Y. In some embodiments, the mating portion 34 is a protrusion extending along the second direction Z, the constraint portion 126 is groove-shaped, the mating portion 34 is inserted into the constraint portion 126, and there is a gap between the mating portion 34 and the constraint portion 126 in the third direction Y, so that the driving member 300 can move relative to the fixed block 124, and the constraint portion 126 can constrain the mating portion 34 to constrain the range of movement of the driving member 300 in the third direction Y, so as to reduce the risk of the driving surface 31 disengaging from the abutment surface 21 during the movement of the driving member 300, so that the driving surface 31 and the abutment surface 21 always remain in contact.

[0059] In some embodiments, the fixing block 124 has a receiving groove 1241 on the side facing the mounting block 43 along the third direction Y. The inner end wall of the receiving groove 1241 away from the mounting block 43 along the third direction Y and the side wall of the mounting block 43 near the fixing block 124 along the third direction Y together form a constraint portion 126, in which the mating portion 34 is received. In other embodiments, the receiving groove 1241 may be omitted, and the side wall of the fixing block 124 facing the mounting block 43 along the third direction Y and the side wall of the mounting block 43 facing the fixing block 124 along the third direction Y together form the constraint portion 126.

[0060] Reference Figure 5 In some embodiments, the pushing surface 32 and the receiving surface 22 may be omitted. For example, the mating hole 23 may be omitted, and the end wall of the stop member 200 near the drive member 300 forms an abutment surface 21. The metal thin-walled semi-solid die-casting mold 1000 also includes an elastic member 500, which connects the stop member 200 and the moving mold 12. The elastic member 500 is configured to provide an elastic force to the stop member 200 to move the stop member 200 away from the discharge channel 1231. For example, the mold core 123 is provided with an abutment groove 1234 along the second direction Z and away from the discharge channel 1231, and the abutment groove 1234 communicates with the sliding hole 1232; the stop member 200 is provided with a receiving part 25, which is inserted into the abutment groove 1234; the elastic member 500 is a spring, which is provided in the abutment groove 1234 and is located on the side of the receiving part 25 along the second direction Z that is close to the discharge channel 1231.

[0061] When the driving member 300 moves in the positive direction of the third direction Y, causing the stop member 200 to move in the positive direction of the second direction Z, the receiving part 25 compresses the elastic member 500, causing the elastic member 500 to undergo elastic deformation, resulting in the elastic member 500 exerting an elastic force on the receiving part 25 in the opposite direction of the second direction Z. When the driving member 300 moves in the opposite direction of the third direction Y, the bearing force of the driving surface 31 on the abutment surface 21 decreases. At this time, the elastic force of the elastic member 500 can cause the stop member 200 to move in the opposite direction of the second direction Z. In other embodiments, the elastic member 500 may also be a rubber pad or other elastic structural member, for example, the elastic member 500 may also be a spring sheet.

[0062] In some embodiments, the elastic element 500 may be omitted, allowing the second direction Z to be approximately parallel to the vertical direction, with the positive direction of the second direction Z being from bottom to top. It is understood that the stop member 200 can move downwards under its own weight, i.e., in the opposite direction of the second direction Z. It is understood that the stop member 200 is located below the discharge channel 1231, and when the stop member 200 moves in the positive direction of the second direction Z, it enters the discharge channel 1231 from bottom to top. In some embodiments, the stop member 200 may be located above the discharge channel 1231. For example, the stop member 200 is located on the fixed mold 11 (see...). Figure 1 When the baffle 200 moves in the positive direction of the second direction Z, the baffle 200 moves away from the discharge channel 1231 from bottom to top.

[0063] In other embodiments, the semi-solid die-casting mold 1000 for thin-walled metal parts further includes a locking fastener disposed on the moving mold 12 and configured to fix the stop 200. After the position of the stop 200 is adjusted, the stop 200 can be fixed by the locking fastener to keep the position of the stop 200 relative to the mold body 100 fixed. Exemplarily, the mold core 123 is provided with a locking screw hole (not shown) along the third direction Y, the locking screw hole communicating with the sliding hole 1232, and the locking fastener is a screw that is threadedly engaged with the locking screw hole; by rotating the locking fastener, the locking fastener can abut against the stop rod to fix the locking rod. It is understood that the head of the locking fastener is located outside the mold core 123, such that at least a portion of the locking fastener is located outside the moving mold 12, so that the locking fastener can be operated to fix the stop 200 without disassembling the moving mold 12.
