Description

Technical Field

[0001] This application relates to the field of molds, and more particularly to the field of die-casting molds, specifically to a type of mold. Background Technology

[0002] Die casting molds are used in the die casting process, a metal forming process in which molten metal is injected into a mold under high pressure and then cooled and solidified. Die casting molds typically consist of a moving mold, a fixed mold, and a sliding block limiting structure. Mold locking is a step in the die casting process, referring to the use of mechanical devices to fix the moving and fixed molds together to ensure that the mold does not move or deform during injection molding or die casting.

[0003] The die-casting mold cavity, which is the forming part that comes into contact with molten metal, is subjected to the impact of molten metal and the pressure during the production process. The linear velocity of molten metal can reach 90 m / s, and the pressure can reach 100 MPa. Therefore, if the mold locking is unstable, the produced castings will have many problems such as severe flash and out-of-tolerance dimensions.

[0004] In existing die-casting molds, a sliding block limiting structure typically engages with the moving and fixed molds to form the cavity. First, the sliding block limiting structure slides into the moving mold. Then, the sliding block limiting structure and the moving mold move together to the fixed mold and close. Finally, clamping force is used to lock the mold. Because mold deformation is inevitable during production, the stability of the fit between the moving and fixed molds is significantly reduced, thus affecting the quality of the casting. Summary of the Invention

[0005] This application provides a mold to at least solve the technical problem of low bonding stability between moving and fixed molds in related technologies. The technical solution of this application is as follows: This application provides a mold, which includes a fixed mold assembly, a moving mold assembly, and a slider assembly. The fixed mold assembly includes a fixed mold frame and a fixed mold core. The fixed mold frame forms a fixed mold cavity, and the fixed mold core is located within and connected to the fixed mold frame. The moving mold assembly is disposed on one side of the fixed mold assembly in a first direction. The moving mold assembly includes a moving mold frame and a moving mold core. The moving mold frame forms a moving mold cavity, and the moving mold core is located within and connected to the moving mold frame. The slider assembly is slidably disposed on the moving mold assembly along a second direction. A portion of the slider assembly can extend into the fixed mold cavity. When a portion of the slider assembly extends into the fixed mold cavity, a cavity is formed between the fixed mold core, the moving mold core, and the portion of the slider assembly extending into the fixed mold cavity. The side of the slider assembly extending into the fixed mold cavity away from the cavity contacts the cavity wall of the fixed mold cavity. The first direction is perpendicular to the second direction.

[0006] The fixed mold assembly has a first plane on the side of the fixed mold cavity closer to the moving mold assembly in the first direction. The first plane is located on one side of the fixed mold cavity in the second direction. The moving mold assembly has a second plane, which is located on one side of the moving mold cavity in the second direction and on the side where the first plane is located. The slider assembly has a third plane and a fourth plane, with the third plane opposite to the first plane and the fourth plane opposite to the second plane. At least one of the first plane and the third plane has a first positioning element protruding along the first direction.

[0007] Based on the aforementioned technical means, this application provides a first plane on the side of the fixed mold assembly closer to the moving mold assembly, and a third plane on the side of the slider assembly closer to the fixed mold assembly. A first positioning element protrudes from at least one of the first and third planes, ensuring that the first and third planes contact and preferentially fit together at the first positioning element during bonding. This first positioning element allows for quick and accurate positioning of the contact point between the first and third planes. Determining the contact point ensures that the two surfaces will not shift or misalign during bonding, thereby improving the stability and reliability of the bonding between the slider assembly and the fixed mold assembly. Furthermore, the structure is simple, easy to position, significantly reduces mold assembly difficulty, and ultimately guarantees the production quality of the casting.

[0008] In addition, by simply adjusting and replacing the first positioning component, the fit reliability between the first and third planes can be better adjusted, greatly reducing mold maintenance costs.

[0009] In one possible implementation, a first mounting groove is provided on at least one of the first plane and the third plane, a portion of the structure of the first positioning member is located in the first mounting groove, and the outer surface of the portion of the structure of the first positioning member abuts against the inner wall of the first mounting groove.

[0010] According to the above technical means, this application sets a first mounting groove on the plane and abuts the part of the first positioning member located in the first mounting groove with the first mounting groove, so that the first mounting groove can limit the first positioning member in the up and down and left and right directions. Thus, when the moving mold assembly is attached to the fixed mold assembly along the first direction, the first positioning member will not be displaced relative to the first mounting groove, thereby ensuring the stability and reliability of the attachment between the first plane and the third plane.

[0011] In one possible implementation, the first positioning element includes a plurality of first positioning blocks, which are spaced apart along a direction perpendicular to the first direction.

[0012] According to the above technical means, the connection of multiple first positioning blocks in this application forms a line fit at a defined position. During the production process, the mold will inevitably deform. At this time, the line fit at a defined position is more stable and reliable than the surface fit of the deformed surface, thereby ensuring the stability and reliability of the fit between the first plane and the third plane.

[0013] In one possible implementation, at least two first positioning blocks have different heights.

[0014] According to the above technical means, the height of two of the multiple first positioning blocks can be the same or different, and can be set according to the gap requirements at multiple mating points. By adjusting the height of multiple first positioning blocks, the mating reliability of the first plane and the third plane can be better controlled, and the mold maintenance cost can be greatly reduced.

[0015] In one possible implementation, at least one of the second plane and the fourth plane is provided with a second positioning element protruding along a second direction.

[0016] According to the above-mentioned technical means, this application provides a second positioning element protruding from at least one of the second plane and the fourth plane, so that the second plane and the fourth plane contact and fit together at the second positioning element during fitting, thereby creating a certain gap between the slider assembly and the fixed mold core and the moving mold core, avoiding mutual squeezing between the slider assembly and the fixed mold core and the moving mold core during the production process, which would affect the processing accuracy and stability of the mold, thereby ensuring the production quality of the casting.

[0017] Furthermore, its simple structure and easy positioning significantly reduce the difficulty of mold assembly, ultimately ensuring the production quality of castings.

[0018] In addition, by simply adjusting and replacing the second positioning component, the gap between the slider assembly and the fixed mold core and the moving mold core can be better adjusted.

[0019] In one possible implementation, a second mounting groove is provided on at least one of the second plane and the fourth plane, a portion of the structure of the second positioning member is located in the second mounting groove, and the outer surface of the portion of the structure of the second positioning member abuts against the inner wall of the second mounting groove.

[0020] According to the above-mentioned technical means, this application sets a second mounting groove on the plane and abuts the second positioning member in the second mounting groove with the second mounting groove. This allows the second mounting groove to limit the second positioning member in the up-down and left-right directions. As a result, the second positioning member will not be displaced relative to the second mounting groove during the process of the slider assembly fitting with the moving mold assembly along the second direction. This ensures the stability and reliability of the fitting between the second plane and the fourth plane, and ultimately ensures that there is always a certain gap between the slider assembly and the fixed mold core and the moving mold core.

[0021] In one possible implementation, the second positioning element includes a plurality of second positioning blocks, which are spaced apart along a direction perpendicular to the second direction.

[0022] According to the above technical means, the connection of multiple second positioning blocks in this application forms a line fit at a defined position. During the production process, the mold will inevitably deform. At this time, the line fit at a defined position is more stable and reliable than the surface fit of the deformed surface, thereby ensuring the stability and reliability of the fit between the second plane and the fourth plane.

[0023] In one possible implementation, at least two of the second positioning blocks have different heights.

[0024] According to the above technical means, the height of two of the multiple second positioning blocks can be the same or different, and can be set according to the gap requirements at multiple mating points. By adjusting the height of multiple second positioning blocks, the mating reliability of the second plane and the fourth plane can be better controlled, and the mold maintenance cost can be greatly reduced.

[0025] In one possible implementation, the cavity wall of the fixed mold cavity includes a side wall and a bottom wall. The portion of the slider assembly extending into the fixed mold cavity has a mating surface on the side away from the cavity. The mating surface contacts the side wall. At least one of the side wall and the mating surface is provided with a third positioning element protruding from the side wall toward the mating surface.

[0026] Based on the aforementioned technical means, this application provides a third positioning element protruding from at least one of the mating surfaces on the side wall of the fixed mold cavity and the sliding block assembly. This allows the side wall of the fixed mold cavity to preferentially contact and fit with the mating surface during mating, reducing wear during sliding between the side wall of the fixed mold cavity and the mating surface. Since mold wear inevitably occurs due to sliding during production, the third positioning element ensures that mold wear primarily occurs on it. After mating, the third positioning element also allows for quick and accurate positioning of the mating point between the side wall of the fixed mold cavity and the mating surface. Determining the mating point ensures that the two surfaces will not shift or misalign during mating, thereby improving the stability and reliability of the mating between the sliding block assembly and the fixed mold assembly. Furthermore, the structure is simple, easy to position, significantly reduces the difficulty of mold assembly, and ultimately ensures the production quality of the casting.

[0027] In addition, by simply adjusting and replacing the third positioning component, the fit reliability between the side wall of the fixed mold cavity and the mating surface can be better adjusted, greatly reducing mold maintenance costs.

[0028] In one possible implementation, the third positioning element includes a plurality of third positioning blocks, which are spaced apart along a direction parallel to the mating surface.

[0029] According to the above technical means, the connection of multiple third positioning blocks in this application forms a line fit at a defined position. During the production process, the mold will inevitably deform. At this time, the line fit at a defined position is more stable and reliable than the surface fit of the deformed mold, thereby ensuring the stability and reliability of the fit between the side wall of the fixed mold cavity and the mating surface.

[0030] This application reduces wear on the sidewall of the fixed mold cavity and the mating surface during sliding by setting multiple third positioning blocks. In the production process, the mold will inevitably wear due to sliding. Setting multiple third positioning blocks can ensure that the wear of the mold mainly occurs on the third positioning blocks. By adjusting or replacing the third positioning blocks, the stability and reliability of the fit between the sidewall of the fixed mold cavity and the mating surface can be guaranteed.

[0031] Therefore, the above-mentioned technical features of this application have the following beneficial effects: (1) By setting a first positioning element, the first plane and the third plane contact and preferentially fit at the first positioning element during the fitting process. This allows for quick and accurate positioning of the fitting point between the first plane and the third plane. Determining the fitting point ensures that the two planes will not shift or misalign during the fitting process, thereby improving the stability and reliability of the fitting between the slider assembly and the fixed mold assembly. Furthermore, the structure is simple and easy to position, which can significantly reduce the difficulty of mold matching and ultimately ensure the production quality of the casting.

[0032] (2) By setting a second positioning element, the second plane and the fourth plane can contact and fit together at the second positioning element during the fitting process. This allows for quick and accurate positioning of the fitting point between the second plane and the fourth plane. Determining the fitting point ensures that the two planes will not shift or misalign during the fitting process, thereby improving the stability and reliability of the fitting between the slider assembly and the moving mold assembly. This also creates a certain gap between the slider assembly and the fixed mold core and the moving mold core, preventing mutual squeezing between the slider assembly and the fixed mold core and the moving mold core during the production process, which would affect the processing accuracy and stability of the mold and thus ensure the production quality of the casting.

[0033] (3) By setting a third positioning element, this application enables the sidewall of the fixed mold cavity and the mating surface to contact and fit together preferentially through the third positioning element during mating. In this way, by setting the third positioning element, the mating point of the sidewall of the fixed mold cavity and the mating surface can be quickly and accurately located. Determining the mating point can ensure that the two surfaces will not shift or misalign during mating, thereby improving the stability and reliability of the mating between the slider assembly and the fixed mold assembly. Moreover, the structure is simple, easy to position, and can significantly reduce the difficulty of mold matching, ultimately ensuring the production quality of the casting.

[0034] In addition, by setting a third positioning component, the wear of the side wall of the fixed mold cavity and the mating surface during sliding can be reduced. During the production process, the mold will inevitably wear due to sliding. Setting a third positioning component can ensure that the wear of the mold mainly occurs on the third positioning component. By adjusting or replacing the third positioning component, the stability and reliability of the fit between the side wall of the fixed mold cavity and the mating surface can be ensured.

[0035] (4) By adjusting and replacing the first positioning component, the second positioning component and the third positioning component, this application enables better adjustment of the fit reliability between the slider assembly and the fixed mold assembly, and between the slider assembly and the moving mold assembly, thereby greatly reducing the mold maintenance cost.

Detailed Implementation

[0040] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0041] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0042] For ease of understanding, the mold provided in this application will be described in detail below with reference to the accompanying drawings.

[0043] refer to Figure 1 In existing die-casting molds, a cavity is generally formed by the sliding block limiting structure 3 cooperating with the fixed mold 1 and the moving mold 2. First, the sliding block limiting structure 3 is slidably engaged with the moving mold 2. Then, the sliding block limiting structure 3 and the moving mold 2 are moved together to the fixed mold 1 and closed with the fixed mold 1. Finally, the mold is locked by the clamping force.

[0044] During mold closing, the surfaces of the moving mold 2 and the slider limiting structure 3 facing the fixed mold 1 are typically fitted together with the surfaces of the fixed mold 1 facing the moving mold 2 and the slider limiting structure 3. However, there is always a gap between the two surfaces, and the fitting position is unpredictable, making mold fitting difficult. If the fitting is not in place, the slider limiting structure 3 will shift, ultimately affecting the quality of the casting.

[0045] In addition, molds inevitably deform during the production process, which greatly reduces the fit stability of the moving and fixed molds, thus affecting the quality of the castings.

[0046] refer to Figure 2 This application provides a mold to solve the technical problem of low bonding stability between moving and fixed molds in related technologies.

[0047] The mold includes a fixed mold assembly 10, a moving mold assembly 20, and a slider assembly 30. The fixed mold assembly 10 includes a fixed mold frame 11 and a fixed mold core 12.

[0048] refer to Figure 3 and Figure 4 and combined Figure 2 The fixed mold frame 11 is provided with a fixed mold cavity 111. The fixed mold core 12 is located inside the fixed mold cavity 111 and connected to the fixed mold frame 11. The moving mold assembly 20 is disposed on one side of the fixed mold assembly 10 in the first direction. The moving mold assembly 20 includes a moving mold frame 21 and a moving mold core 22. The moving mold frame 21 forms a moving mold cavity 211, and the moving mold core 22 is located inside the moving mold cavity 211 and connected to the moving mold frame 21. The slider assembly 30 is slidably disposed on the moving mold assembly 20 along the second direction. A portion of the slider assembly 30 can extend into the fixed mold cavity 111. When a portion of the slider assembly 30 extends into the fixed mold cavity 111, a cavity 50 is formed between the fixed mold core 12, the moving mold core 22, and the portion of the slider assembly 30 extending into the fixed mold cavity 111. The side of the slider assembly 30 extending into the fixed mold cavity 111 away from the cavity 50 contacts the cavity wall of the fixed mold cavity 111. The first direction is perpendicular to the second direction. The first direction is... Figure 2 The vertical direction shown, the second direction is Figure 2 The left and right directions are shown.

[0049] refer to Figure 5 and Figure 6 and combined Figure 3 The mold closing process is as follows: First, the slider assembly 30 slides along the second direction and fits against the moving mold assembly 20; then, the slider assembly 30 and the moving mold assembly 20 move together along the first direction and fit against the fixed mold assembly 10. At this time, a portion of the slider assembly 30 extends into the fixed mold cavity 111. The left side of the portion of the slider assembly 30 extending into the fixed mold cavity 111 fits against the side wall 1111 of the fixed mold cavity 111, and the right side surrounds the fixed mold core 12 and the moving mold core 22 to form a cavity 50 (see...). Figure 2 The mold is closed. Cavity 50 is used for filling with molten metal, which solidifies to form a casting.

[0050] After the mold is closed, the die-casting machine will also provide a clamping force to lock the mold in order to carry out normal production.

[0051] Continue to refer to Figure 2 and combined Figure 3 and Figure 4The fixed mold assembly 10 has a first plane 112 on the side of the moving mold assembly 20 in the first direction. The first plane 112 is located on one side of the fixed mold cavity 111 in the second direction. The moving mold assembly 20 has a second plane 212, which is located on one side of the moving mold cavity 211 in the second direction and on the side where the first plane 112 is located.

[0052] The slider assembly 30 is provided with a third plane 311 and a fourth plane 312. The third plane 311 is opposite to the first plane 112, and the fourth plane 312 is opposite to the second plane 212. That is, the first plane 112 and the second plane 212 are located on the left side of the fixed mold cavity 111 and the moving mold cavity 211, respectively.

[0053] Continue to refer to Figure 2 At least one of the first plane 112 and the third plane 311 is provided with a first positioning member 41 protruding along the first direction, that is, the first positioning member 41 is provided on the first plane 112, or the first positioning member 41 is provided on the third plane 311, or the first positioning member 41 is provided on both the first plane 112 and the third plane 311.

[0054] Continue to refer to Figure 2 , Figure 3 and Figure 5 When the first positioning element 41 protrudes from the third plane 311, during the process of the slider assembly 30 and the moving mold assembly 20 moving together along the first direction and fitting with the fixed mold assembly 10, the first plane 112 and the third plane 311 first contact and preferentially fit at the first positioning element 41. In this way, the fitting point of the first plane 112 and the third plane 311 can be quickly and accurately located. Determining the fitting point can ensure that the two surfaces will not shift or misalign during fitting. At this time, there is a certain gap between the slider assembly 30 and the bottom wall 1113 of the fixed mold cavity 111, and between the moving mold frame 21 and the fixed mold frame 11. After the clamping force is applied, the gap between the slider assembly 30 and the bottom wall 1113 of the fixed mold cavity 111, and between the moving mold frame 21 and the fixed mold frame 11 is eliminated. Thus, the surface of the moving mold frame 21 facing the fixed mold frame 11 and the surface of the fixed mold frame 11 facing the moving mold frame 21 form a support, ensuring the stability of the mold during the production process.

[0055] Understandably, the size of the gap between the slider assembly 30 and the bottom wall 1113 of the fixed mold cavity 111, and between the moving mold frame 21 and the fixed mold frame 11, can be reserved according to the deformation after applying the clamping force, as long as the gap is eliminated after applying the clamping force.

[0056] Based on this, this application provides a first positioning element 41 protruding on the third plane 311, so that the first plane 112 and the third plane 311 first contact and preferentially fit at the first positioning element 41 during fitting, thereby improving the stability and reliability of the fitting between the slider assembly 30 and the fixed mold assembly 10, and ultimately ensuring the production quality of the casting.

[0057] In addition, by protruding the first positioning element 41, the structure is not only simple, but the difficulty of mold assembly can be significantly reduced.

[0058] In some possible embodiments, the first positioning member 41 and the slider assembly 30 are an integral structure. Of course, the first positioning member 41 and the slider assembly 30 can also be separate structures. The first positioning member 41 can be fixedly connected to the slider assembly 30 by means of threaded connection, snap-fit, etc.

[0059] Based on this, this application can better adjust the fit reliability between the first plane 112 and the third plane 311 by simply adjusting and replacing the first positioning component 41, thus solving the problem of dimensional setback after long-term mold production and greatly reducing mold maintenance costs.

[0060] For example, the shape of the first positioning member 41 can be set as needed. The shape of the first positioning member 41 can be a cylinder, a cuboid, etc., and this embodiment does not specifically limit it.

[0061] When the first positioning element 41 protrudes from the first plane 112, or when the first positioning element 41 protrudes from both the first plane 112 and the third plane 311, the process of the slider assembly 30 and the moving mold assembly 20 moving together along the first direction and fitting with the fixed mold assembly 10 is the same as the fitting process with the first positioning element 41 protruding from the third plane 311 described above in terms of principle and technical effect. This embodiment will not be elaborated here.

[0062] refer to Figure 7 and combined Figure 2 In some embodiments, at least one of the first plane 112 and the third plane 311 is provided with a first mounting groove 3111, a portion of the structure of the first positioning member 41 is located in the first mounting groove 3111, and the outer surface of the portion of the structure of the first positioning member 41 abuts against the inner wall of the first mounting groove 3111.

[0063] Based on this, this application sets a first mounting groove 3111 on the plane and abuts the first positioning member 41 in the first mounting groove 3111 with the part of the structure of the first positioning member 41 located in the first mounting groove 3111. This allows the first mounting groove 3111 to limit the first positioning member 41 in the up-down and left-right directions. As a result, during the process of the moving mold assembly 20 fitting with the fixed mold assembly 10 along the first direction, the first positioning member 41 will not be displaced relative to the first mounting groove 3111, thereby ensuring the stability and reliability of the fitting between the first plane 112 and the third plane 311.

[0064] For example, the shape of the first mounting groove 3111 can be set as needed, and the size of the first mounting groove 3111 can also be set as needed, as long as the part of the first positioning member 41 located in the first mounting groove 3111 does not shift between itself and the first mounting groove 3111.

[0065] The first positioning component 41 can be fixedly connected to the first mounting groove 3111 by means of threaded connection, snap-fit, etc.

[0066] In some possible embodiments, an internal thread is provided on the inner peripheral wall of the first mounting groove 3111, and an external thread is provided on the outer peripheral wall of the first positioning member 41. The internal thread and the external thread cooperate to fix the first positioning member 41 to the first mounting groove 3111.

[0067] Continue to refer to Figure 2 and Figure 7 In some embodiments, the first positioning member 41 includes a plurality of first positioning blocks, which are spaced apart along a direction perpendicular to the first direction, i.e., the plurality of first positioning blocks are linearly arranged along a direction parallel to the first plane 112.

[0068] Based on this, the connection of multiple first positioning blocks in this application forms a line fit at a defined position. During the production process, the mold will inevitably deform. At this time, the line fit at the defined position is more stable and reliable than the surface fit of the deformed part, thereby ensuring the stability and reliability of the fit between the first plane 112 and the third plane 311.

[0069] Furthermore, the multiple first positioning blocks are arranged linearly in one direction, which facilitates precise control of the spacing and position between the multiple first positioning blocks and makes it easy to obtain the height of the first positioning blocks required for the first plane 112 and the third plane 311 to fit together. By quickly replacing the appropriate first positioning blocks, the stability and reliability of the fit between the first plane 112 and the third plane 311 are ensured.

[0070] For example, the number of first positioning blocks can be set as needed. The first positioning blocks can be set to two or more. This embodiment does not specifically limit this.

[0071] In some possible embodiments, at least two of the first positioning blocks have different heights. The heights of two of the plurality of first positioning blocks may be the same or different, depending on the gap requirements at the multiple mating points.

[0072] Deformation of the mold is inevitable during long-term production. The distance between the first plane 112 and the third plane 311 is not always equal. Replacing the first positioning block with one of different heights according to the actual situation is beneficial to the stability and reliability of the fit between the first plane 112 and the third plane 311.

[0073] Based on this, this application can control the bonding reliability by adjusting and replacing the height of the first positioning block, which greatly reduces the mold maintenance cost.

[0074] Continue to refer to Figure 2 and Figure 7 In some embodiments, at least one of the second plane 212 and the fourth plane 312 is provided with a second positioning member 42 protruding along the second direction, that is, the second positioning member 42 is provided on the second plane 212, or the second positioning member 42 is provided on the fourth plane 312, or the first positioning member 41 is provided on both the second plane 212 and the fourth plane 312.

[0075] When the second positioning member 42 protrudes from the fourth plane 312, during the process of the slider assembly 30 sliding along the second direction and fitting with the moving mold assembly 20, the second positioning member 42 will preferentially contact and abut against the second plane 212 to complete the fitting of the slider assembly 30 and the moving mold assembly 20.

[0076] Based on this, this application provides a second positioning element 42 protruding from the fourth plane 312. The second plane 212 and the fourth plane 312 contact and fit at the second positioning element 42, so that after the slider assembly 30 and the moving mold assembly 20 are fitted together, there is a certain gap between the slider assembly 30 and the fixed mold core 12 and the moving mold core 22. This avoids the slider assembly 30 from being squeezed against the fixed mold core 12 and the moving mold core 22 due to thermal expansion during the production process, which would affect the processing accuracy and stability of the mold, thereby ensuring the production quality of the casting and the service life of the mold.

[0077] In addition, the second plane 212 and the fourth plane 312 contact and fit at the second positioning member 42, which can quickly and accurately locate the fitting point of the second plane 212 and the fourth plane 312. Determining the fitting point can ensure that the two surfaces will not shift or misalign during fitting, thereby improving the stability and reliability of the fitting between the slider assembly 30 and the moving mold assembly 20.

[0078] This application can better adjust the fit reliability between the second plane 212 and the fourth plane 312, as well as the gap size between the slider assembly 30 and the fixed mold core 12 and the moving mold core 22, simply by adjusting and replacing the second positioning component 42, thus greatly reducing mold maintenance costs.

[0079] For example, the shape of the second positioning member 42 can be set as needed. The shape of the second positioning member 42 can be a cylinder, a cuboid, etc., and this embodiment does not specifically limit it.

[0080] When the second positioning element 42 protrudes from the second plane 212, or when the second positioning element 42 protrudes from both the second plane 212 and the fourth plane 312, the principle and technical effect of the bonding process are the same as those of the bonding process where the second positioning element 42 protrudes from the fourth plane 312, during the sliding of the slider assembly 30 along the second direction and its contact with the moving mold assembly 20. This embodiment will not be described in detail here.

[0081] Continue to refer to Figure 2 and Figure 7 In some embodiments, at least one of the second plane 212 and the fourth plane 312 is provided with a second mounting groove 3121, a portion of the structure of the second positioning member 42 is located in the second mounting groove 3121, and the outer surface of the portion of the structure of the second positioning member 42 abuts against the inner wall of the second mounting groove 3121.

[0082] Based on this, this application provides a second mounting groove 3121 on the plane and abuts the second positioning member 42 in the second mounting groove 3121 with the second mounting groove 3121. This allows the second mounting groove 3121 to limit the second positioning member 42 in the up-down and left-right directions. As a result, the second positioning member 42 will not be displaced relative to the second mounting groove 3121 during the process of the slider assembly 30 fitting with the moving mold assembly 20 along the second direction. This ensures the stability and reliability of the fitting between the second plane 212 and the fourth plane 312.

[0083] For example, the shape of the second mounting groove 3121 can be set as needed, and the size of the second mounting groove 3121 can also be set as needed, as long as the part of the second positioning member 42 located in the second mounting groove 3121 does not shift between the second mounting groove 3121 and the second mounting groove 3121.

[0084] The second positioning element 42 can be fixedly connected to the second mounting groove 3121 by means of threaded connection, snap-fit, etc.

[0085] In some possible embodiments, an internal thread is provided on the inner peripheral wall of the second mounting groove 3121, and an external thread is provided on the outer peripheral wall of the second positioning member 42. The internal thread and the external thread cooperate to fix the second positioning member 42 to the second mounting groove 3121.

[0086] Continue to refer to Figure 2 and Figure 7 In some embodiments, the second positioning member 42 includes a plurality of second positioning blocks, which are spaced apart along a direction perpendicular to the second direction, that is, the plurality of second positioning blocks are linearly arranged along a direction parallel to the second plane 212.

[0087] Based on this, the connection of multiple second positioning blocks in this application forms a line fit at a defined position. During the production process, the mold will inevitably deform. At this time, the line fit at a defined position is more stable and reliable than the surface fit of the deformed part, thereby ensuring the stability and reliability of the fit between the second plane 212 and the fourth plane 312.

[0088] Multiple second positioning blocks are arranged linearly in one direction, which facilitates precise control of the spacing and position between the second positioning blocks and makes it easy to obtain the height of the second positioning blocks required for the second plane 212 and the fourth plane 312 to fit together. By quickly replacing the appropriate second positioning blocks, the stability and reliability of the fit between the second plane 212 and the fourth plane 312 are ensured.

[0089] For example, the number of second positioning blocks can be set as needed. There can be two or more second positioning blocks. This embodiment does not make a specific limitation on this.

[0090] In some possible embodiments, at least two of the second positioning blocks have different heights. The heights of two of the plurality of second positioning blocks may be the same or different, depending on the gap requirements at the multiple mating points.

[0091] Deformation of the mold is inevitable during long-term production. The distance between the second plane 212 and the fourth plane 312 is not always equal. Replacing the second positioning block with a different height according to the actual situation is beneficial to the stability and reliability of the fit between the second plane 212 and the fourth plane 312.

[0092] Based on this, this application can control the fitting reliability by adjusting the height of the second positioning block, which greatly reduces the mold maintenance cost.

[0093] refer to Figure 8 and combined Figure 2In some embodiments, the slider assembly 30 includes a connected slide block 31 and a slider 32, with the slide block 31 located on the side of the slider 32 away from the cavity 50, and the cavity 50 is formed between the fixed mold core 12, the moving mold core 22 and the portion of the slider 32 that extends into the fixed mold cavity 111.

[0094] For example, the slide block 31 can be fixedly connected to the slider 32 by means of threaded connection, snap-fit, etc.

[0095] Continue to refer to Figure 3 and Figure 8 The cavity wall of the fixed mold cavity 111 includes a side wall 1111 and a bottom wall 1113. The portion of the slider assembly 30 extending into the fixed mold cavity 111 is away from the cavity 50 (see [reference]). Figure 2 On one side of the slide block 31, that is, the part of the slide block 31 that extends into the fixed mold cavity 111 and is away from the cavity 50, a mating surface 313 is provided. The mating surface 313 contacts the side wall 1111. At least one of the side wall 1111 and the mating surface 313 is provided with a third positioning element 43 protruding from the side wall 1111 towards the mating surface 313. That is, the third positioning element 43 is provided on the side wall 1111, or the third positioning element 43 is provided on the mating surface 313, or the third positioning element 43 is provided on both the side wall 1111 and the mating surface 313.

[0096] When a third positioning element 43 protrudes from the side wall 1111 of the fixed mold cavity 111, during the process of the slider assembly 30 and the moving mold assembly 20 moving together in the first direction and fitting with the fixed mold assembly 10, the third positioning element 43 will contact the mating surface 313. After the mold is closed, the third positioning element 43 and the mating surface 313 fit stably.

[0097] Based on this, this application provides a third positioning element 43 protruding from the side wall 1111 of the fixed mold cavity 111, so that the side wall 1111 of the fixed mold cavity 111 and the mating surface 313 first contact and fit through the third positioning element 43 during mating. This can reduce the wear when the side wall 1111 of the fixed mold cavity 111 and the mating surface 313 slide during molding. In the production process, the mold will inevitably wear due to sliding. The third positioning element 43 can ensure that the mold wear mainly occurs on the third positioning element 43. By adjusting or replacing the third positioning element 43, the stability and reliability of the fit between the side wall 1111 of the fixed mold cavity 111 and the mating surface 313 can be guaranteed.

[0098] After bonding is completed, the bonding point of the side wall 1111 of the fixed mold cavity 111 and the mating surface 313 can be quickly and accurately located by setting the third positioning component 43. Determining the bonding point can ensure that the two surfaces will not shift or misalign during bonding, thereby improving the stability and reliability of bonding between the slider assembly 30 and the fixed mold assembly 10. Moreover, the structure is simple and easy to position, which can significantly reduce the difficulty of mold matching and ultimately ensure the production quality of the casting.

[0099] In addition, by protruding the third positioning element 43, the structure is not only simple, but the difficulty of mold assembly can be significantly reduced.

[0100] Understandably, the size of the gap between the slider assembly 30 and the fixed mold core 12 and the moving mold core 22 is related to the height of the second positioning member 42 and the third positioning member 43. When a larger gap is required, the height of the second positioning member 42 needs to be larger, and correspondingly, the height of the third positioning member 43 needs to be smaller.

[0101] In some possible embodiments, the third positioning member 43 and the fixed mold assembly 10 are an integral structure. Of course, the third positioning member 43 and the fixed mold assembly 10 can also be separate structures. The third positioning member 43 can be fixedly connected to the fixed mold assembly 10 by means of threaded connection, snap-fit, etc.

[0102] Based on this, this application can better adjust the fit reliability between the side wall 1111 of the fixed mold cavity 111 and the mating surface 313 by simply adjusting and replacing the third positioning component 43, thus solving the problem of dimensional setback after long-term mold production and greatly reducing mold maintenance costs.

[0103] For example, the shape of the third positioning member 43 can be set as needed. The shape of the third positioning member 43 can be a cylinder, a cuboid, etc., and this embodiment does not specifically limit it.

[0104] When a third positioning element 43 protrudes from the mating surface 313, or when a third positioning element 43 protrudes from both the side wall 1111 of the fixed mold cavity 111 and the mating surface 313, the process in which the slider assembly 30 and the moving mold assembly 20 move together along the first direction and fit together with the fixed mold assembly 10 is the same as the fitting process in principle and achieves the same technical effect as the process in which a third positioning element 43 protrudes from the side wall 1111 of the fixed mold cavity 111. This embodiment will not be elaborated here.

[0105] refer to Figure 9 and combined Figure 3 and Figure 5 In some embodiments, at least one of the sidewall 1111 of the fixed mold cavity 111 and the mating surface 313 is provided with a third mounting groove 1112, and a portion of the structure of the third positioning member 43 is located in the third mounting groove 1112, with the outer surface of the portion of the third positioning member 43 abutting against the inner wall of the third mounting groove 1112.

[0106] Based on this, this application sets a third mounting groove 1112 and abuts the third positioning member 43 in the third mounting groove 1112 with the third mounting groove 1112, so that the third mounting groove 1112 can limit the third positioning member 43 in the up and down and left and right directions. Thus, when the slider assembly 30 is fitted with the fixed mold assembly 10 in the first direction, the third positioning member 43 will not be displaced relative to the third mounting groove 1112, thereby ensuring the stability and reliability of the fit between the side wall 1111 of the fixed mold cavity 111 and the mating surface 313.

[0107] For example, the shape of the third mounting groove 1112 can be set as needed, and the size of the third mounting groove 1112 can also be set as needed, as long as the part of the third positioning member 43 located in the third mounting groove 1112 does not shift between itself and the third mounting groove 1112.

[0108] The third positioning component 43 can be fixedly connected to the third mounting slot 1112 by means of threaded connection, snap-fit, etc.

[0109] In some possible embodiments, an internal thread is provided on the inner peripheral wall of the third mounting groove 1112, and an external thread is provided on the outer peripheral wall of the third positioning member 43. The internal thread and the external thread cooperate to fix the third positioning member 43 to the third mounting groove 1112.

[0110] Continue to refer to Figure 5 and Figure 9 In some embodiments, the third positioning member 43 includes a plurality of third positioning blocks, which are spaced apart along a direction parallel to the mating surface 313.

[0111] Based on this, the connection of multiple third positioning blocks in this application forms a line fit at a defined position. During the production process, the mold will inevitably deform. At this time, the line fit at a defined position is more stable and reliable than the surface fit of the deformed mold, thereby ensuring the stability and reliability of the fit between the side wall 1111 of the fixed mold cavity 111 and the mating surface 313.

[0112] By setting multiple third positioning blocks, this application can reduce the wear of the side wall 1111 of the fixed mold cavity 111 and the mating surface 313 during the sliding process. In the production process, the mold will inevitably wear due to sliding. Setting multiple third positioning blocks can ensure that the mold wear mainly occurs on the third positioning blocks. By adjusting or replacing the third positioning blocks, the stability and reliability of the fit between the side wall 1111 of the fixed mold cavity 111 and the mating surface 313 can be guaranteed.

[0113] Multiple third positioning blocks are arranged linearly in one direction, which facilitates precise control of the spacing and position between the third positioning blocks and makes it easy to obtain the height of the third positioning blocks required for the sidewall 1111 of the fixed mold cavity 111 to fit with the mating surface 313. By quickly replacing the appropriate third positioning blocks, the stability and reliability of the fit between the sidewall 1111 of the fixed mold cavity 111 and the mating surface 313 are ensured.

[0114] For example, the number of third positioning blocks can be set as needed. There can be two or more third positioning blocks. This embodiment does not make a specific limitation on this.

[0115] In some possible embodiments, at least two of the third positioning blocks have different heights. The heights of two of the plurality of third positioning blocks may be the same or different, depending on the gap requirements at the multiple mating points.

[0116] Deformation is inevitable during long-term production. The distance between the side wall 1111 of the fixed mold cavity 111 and the mating surface 313 is not always equal. Replacing the third positioning block with a different height according to the actual situation is beneficial to the stability and reliability of the fit between the side wall 1111 of the fixed mold cavity 111 and the mating surface 313.

[0117] Based on this, this application can control the bonding reliability by adjusting the height of the third positioning block, which greatly reduces the mold maintenance cost.

[0118] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
