Description

Technical Field

[0001] This application relates to the field of mold technology, and more specifically, to adjustment mechanisms and molds. Background Technology

[0002] During the mold manufacturing process, if the type or material of the product changes, the height of the mold cavity needs to be adjusted accordingly to meet the processing requirements of different types of products.

[0003] In related technologies, the height of the mold cavity is usually changed by replacing the limiting pins inside the mold. However, this method has the problem of inconvenient adjustment. Utility Model Content

[0004] This application provides an adjustment mechanism and a mold to solve the technical problem of inconvenient operation of adjusting the height of the mold cavity in related technologies.

[0005] The embodiments of this application are implemented as follows: In a first aspect, this application provides an adjustment mechanism disposed between an upper mold and a lower mold. The surface of the upper mold facing the lower mold along a first direction is a first surface, which includes a first surface region and a second surface region. The surface of the lower mold facing the upper mold along the first direction is a second surface, which includes a third surface region and a fourth surface region. A mold cavity is formed between the first surface region and the third surface region. The adjustment mechanism includes: a base for connecting one of the second surface region and the fourth surface region, and corresponding to the other of the second surface region and the fourth surface region along the first direction; and an adjustment member. The component includes a first adjustment surface and a second adjustment surface. The adjustment component is movably disposed on the base. The first adjustment surface abuts against the base. The second adjustment surface is used to abut against another of the second surface area and the fourth surface area. The second adjustment surface includes multiple adjustment surface segments. The distance between the multiple adjustment surface segments and the first adjustment surface is different from each other. The adjustment component is used to move relative to the base so that different adjustment surface segments abut against another of the second surface area and the fourth surface area, thereby driving the upper mold to move closer to or away from the lower mold along a first direction to adjust the distance between the first surface area and the third surface area.

[0006] According to the adjustment mechanism of this application, during normal mold operation, one of the adjustment surfaces abuts against one of the second or fourth surfaces. When it is necessary to adjust the size of the mold cavity along the first direction, the upper and lower molds are separated along the first direction, causing the upper or lower mold to separate from the adjustment component. Subsequently, the adjustment component is moved so that the other adjustment surface corresponds to one of the second or fourth surfaces along the first direction, and then the upper and lower molds are closed along the first direction, causing the adjustment surface to abut against the second surface. This causes a change in the size of the mold cavity along the first direction. Compared to related technologies that require replacing support structures of different sizes, moving the adjustment component is convenient and quick, thereby improving the ease of adjusting the size of the mold cavity along the first direction.

[0007] In one possible implementation: The base is provided with at least one first limiting part; the adjusting member is provided with a plurality of second limiting parts, each adjusting surface segment corresponds to at least one second limiting part, and at least one first limiting part selectively limits and cooperates with at least one second limiting part corresponding to the adjusting surface segment, so that the corresponding adjusting surface segment remains in contact with the other of the second surface area and the fourth surface area.

[0008] In one possible implementation: The adjustment mechanism further includes multiple elastic parts, each of which elastically abuts against the base and the corresponding first limiting part.

[0010] In one possible implementation: The base has a groove on the side facing the first adjustment surface. The extension direction of the groove is parallel to the length direction of the adjustment member. The adjustment member is slidably fitted in the groove. The first adjustment surface is in contact with the bottom surface of the groove. The first limiting part is provided on the side of the groove, and the second limiting part is provided on the edge of the adjustment member along its width direction.

[0011] In one possible implementation: The first adjustment surface has an adjustment groove, the extension direction of which is parallel to the length direction of the adjustment member; the base has a third limiting part, the third limiting part extends toward the first adjustment surface and extends into the adjustment groove, the third limiting part is used to limit the movement stroke of the adjustment member relative to the base.

[0012] In one possible implementation: The number of second surface areas is multiple, and multiple second surface areas are arranged around the first surface area circumferentially. The number of second adjustment surfaces is multiple, and multiple second adjustment surfaces are arranged at intervals circumferentially around the first surface area. Each second adjustment surface is arranged corresponding to one of the second surface areas. Alternatively, the number of fourth surface areas is multiple, and multiple fourth surface areas are arranged around the first surface area circumferentially around the third surface area. The number of second adjustment surfaces is multiple, and multiple second adjustment surfaces are arranged at intervals circumferentially around the third surface area. Each second adjustment surface is arranged corresponding to one of the fourth surface areas.

[0013] In one possible implementation: The second surface area is divided into two groups of second surface areas, which are located on both sides of the first surface area along the second direction. Each second surface area includes multiple second surface areas distributed along the third direction. The number of adjustment members is two, which are located on both sides of the first surface area along the second direction. Each adjustment member corresponds to one of the second surface areas. Alternatively, the fourth surface area is divided into two groups of fourth surface areas, which are located on both sides of the third surface area along the second direction. Each fourth surface area includes multiple fourth surface areas distributed along the third direction. The number of adjustment members is two, which are located on both sides of the third surface area along the second direction. Each adjustment member corresponds to one of the fourth surface areas.

[0014] Secondly, this application provides a mold, comprising: an upper mold having a first surface, the first surface including a first surface area and a second surface area; a lower mold disposed opposite to the upper mold along a first direction, the surface of the lower mold facing the upper mold along the first direction being a second surface, the second surface including a third surface area and a fourth surface area, a mold cavity being formed between the first surface area and the third surface area; and the aforementioned adjustment mechanism disposed between the second surface area and the fourth surface area.

[0029] 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 herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0031] See Figure 1 and Figure 2 This embodiment provides a mold 200, including an upper mold 201, a lower mold 202, and an adjustment mechanism 100. The upper mold 201 has a first surface P1, which includes a first surface area P11 and a second surface area P12. The lower mold 202 is disposed opposite to the upper mold 201 along a first direction X. The surface of the lower mold 202 facing the upper mold 201 along the first direction X is a second surface P2, which includes a third surface area P21 and a fourth surface area P22. A mold cavity Q is formed between the first surface area P11 and the third surface area P21. The adjustment mechanism 100 is disposed between the second surface area P12 and the fourth surface area P22.

[0032] In some embodiments, the first direction X is perpendicular to the second surface region P12 and the fourth surface region P22.

[0033] In some embodiments, along the first direction X, the first surface region P11 and the third surface region P21 are both located on the side of the fourth surface region P22 that is away from the second surface region P12.

[0034] Optionally, see Figure 2 The lower mold 202 has a groove formed on the second surface P2, and the bottom surface of the groove is the third surface area P21. The mold 200 also includes an upper punch plate 203. The upper punch plate 203 is connected to the upper mold 201 and extends towards the lower mold 202 along the first direction X relative to the second surface area P12. The surface of the upper punch plate 203 facing away from the upper mold 201 along the first direction X is the first surface area P11.

[0035] See Figure 2 and Figure 3The adjustment mechanism 100 includes a base 10 and an adjustment member 20. The base 10 is used to connect one of the second surface area P12 and the fourth surface area P22, and corresponds to the other of the second surface area P12 and the fourth surface area P22 along the first direction X. The adjustment member 20 includes a first adjustment surface P3 and a second adjustment surface P4. The adjustment member 20 is movably disposed on the base 10. The first adjustment surface P3 abuts against the base 10, and the second adjustment surface P4 is used to abut against the other of the second surface area P12 and the fourth surface area P22. The second adjustment surface P4 includes multiple adjustment surface segments P41. The distance between the multiple adjustment surface segments P41 and the first adjustment surface P3 is different. The adjustment member 20 is used to move relative to the base 10 so that different adjustment surface segments P41 abut against the other of the second surface area P12 and the fourth surface area P22, thereby driving the upper mold 201 to move closer to or further away from the lower mold 202 along the first direction X, so as to adjust the distance between the first surface area P11 and the third surface area P21.

[0036] According to the adjustment mechanism 100 of this embodiment, during the normal operation of the mold 200, one of the adjustment surfaces P41 abuts against either the second surface area P12 or the fourth surface area P22. When it is necessary to adjust the size of the mold cavity Q along the first direction X, the upper mold 201 and the lower mold 202 are separated along the first direction X, so that the upper mold 201 or the lower mold 202 is separated from the adjustment member 20. Then, the adjustment member 20 is moved so that the other adjustment surface P41 corresponds to either the second surface area P12 or the fourth surface area P22 along the first direction X, and then the upper mold 201 and the lower mold 202 are closed along the first direction X, so that the adjustment surface P41 abuts against either the second surface area P12. This causes the size of the mold cavity Q to change along the first direction X. Compared to related technologies that require replacing support structures of different sizes, moving the adjustment member 20 is convenient and quick, thereby improving the ease of adjusting the size of the mold cavity Q along the first direction X.

[0037] In related technologies, when a mold 200 forms a workpiece in the mold cavity Q through stretching or other forming methods, changing the material alters the material's microstructure, causing changes in the workpiece's ductility and other properties, and consequently, the workpiece's forming dimensions along the first direction X. With the mold 200 of this embodiment, different products can be matched with different adjustment surfaces P41. After changing to a product with different properties, the adjustment member 20 can be moved until the corresponding adjustment surface P41 aligns with the second surface area P12 or the fourth surface area P22 along the first direction X, thus offering the advantage of convenient adjustment.

[0038] In this embodiment, the adjusting member 20 is fixedly connected to the fourth surface region P22, and multiple adjusting surface segments P41 are correspondingly arranged with the second surface region P12. In other embodiments, the adjusting member 20 may also be fixedly connected to the second surface region P12, and multiple adjusting surface segments P41 may be correspondingly arranged with the fourth surface region P22.

[0039] In some embodiments, see Figure 4 and Figure 5 There are multiple second surface areas P12, which are arranged around the first surface area P11 in the circumferential direction. There are multiple second adjustment surfaces P4, which are arranged at intervals in the circumferential direction of the first surface area P11. Each second adjustment surface P4 corresponds to one of the second surface areas P12.

[0040] In this way, the adjusting member 20 can stably support the upper mold 201 at all points along the circumference of the first surface area P11, which can ensure the structural stability of the cavity and thus improve the processing reliability of the product.

[0041] In some embodiments, see Figure 5 The mold 200 also includes a limiting post 204. The limiting post 204 is connected to the upper mold 201 and extends from the first surface P1 toward the lower mold 202 along the first direction X. The end face of the limiting post 204 toward the lower mold 202 is the second surface area P12. The limiting post 204 and the base 10 of the adjusting mechanism 100 are correspondingly arranged along the first direction X.

[0042] Optionally, the base 10 can be fixedly connected to the lower mold 202 by fasteners such as screws.

[0043] In some embodiments, there are multiple fourth surface regions P22, which are arranged around the first surface region P11 along the circumference of the third surface region P21. There are multiple second adjustment surfaces P4, which are arranged at intervals along the circumference of the third surface region P21. Each second adjustment surface P4 corresponds to one of the fourth surface regions P22.

[0044] In this way, the adjusting component 20 can stably abut against the lower mold 202 at all points along the circumference of the third surface area P21, which can ensure the structural stability of the cavity and thus improve the processing reliability of the product.

[0045] Optionally, the second surface area P12 is divided into two groups of second surface groups. The two groups of second surface groups are located on both sides of the first surface area P11 along the second direction Y. The second surface group includes multiple second surface areas P12 distributed along the third direction Z. The number of adjustment members 20 is two. The two adjustment members 20 are arranged on both sides of the first surface area P11 along the second direction Y. Each adjustment member 20 is corresponding to one second surface group.

[0046] Optionally, the fourth surface region P22 is divided into two groups of fourth surface regions. The two groups of fourth surface regions are located on both sides of the third surface region P21 along the second direction Y. Each fourth surface region includes multiple fourth surface regions P22 distributed along the third direction Z. The number of adjustment members 20 is two. The two adjustment members 20 are arranged on both sides of the third surface region P21 along the second direction Y. Each adjustment member 20 is corresponding to one of the fourth surface regions.

[0047] In some embodiments, see Figure 6 The length direction of the adjusting member 20 is parallel to the third direction Z. There are two bases 10. The two bases 10 are respectively located on both sides of the first surface region P11 along the second direction Y. There are also two adjusting members 20, each movably located on its corresponding base 10 along the third direction Z. Each adjusting member 20 forms two second adjusting surfaces P4. The two second adjusting surfaces P4 are spaced apart along the third direction Z. Each second adjusting surface P4 includes multiple adjusting surface segments P41 distributed along the third direction Z. The two second adjusting surfaces P4 are located on both sides of the first surface region P11 along the second direction Y. Thus, the two adjusting members 20 can stably support the first surface region P11 between the upper mold 201 and the lower mold 202 on both sides along the second direction Y and both sides along the third direction Z (i.e., the circumferential direction of the first surface region P11).

[0048] In other embodiments, the number of adjusting members 20 may also be multiple. Multiple or two adjusting members 20 may also be connected to form a single integral component. This embodiment does not specifically limit the formation method of the multiple adjusting surface segments P41.

[0049] In some embodiments, see Figure 6 The base 10 is provided with at least one first limiting part 31. The adjusting member 20 is provided with a plurality of second limiting parts 32, and each adjusting surface segment P41 corresponds to at least one second limiting part 32. At least one first limiting part 31 selectively limits and engages with at least one second limiting part 32 corresponding to the adjusting surface segment P41, so that the corresponding adjusting surface segment P41 remains in contact with the other of the second surface area P12 and the fourth surface area P22.

[0050] Optionally, the adjusting member 20 has multiple second limiting portions 32 on both sides in the width direction. The base 10 has at least one first limiting portion 31 on both sides in the width direction of the adjusting member 20. This can improve the stability of the base 10 and the adjusting member 20 when they are in a limiting engagement state.

[0051] In some embodiments, see Figures 7 to 9The adjustment mechanism 100 also includes a plurality of elastic parts 33, each elastic part 33 elastically abutting against the base 10 and the corresponding first limiting part 31. The elastic part 33 is used to apply elastic force to the first limiting part 31 so that the first limiting part 31 and the corresponding second limiting part 32 maintain a limiting fit.

[0052] Thus, when the adjusting member 20 is moved, it can apply an elastic force to the elastic part 33, causing the first limiting part 31 and the second limiting part 32 to disengage from their limiting engagement. This allows the adjusting member 20 to move relative to the base 10, facilitating the switching to the next adjusting surface segment P41 abutting against the second surface area P12 or the fourth surface area P22. After the adjusting member 20 has moved, the elastic force of the elastic part 33 keeps the first limiting part 31 and the second limiting part 32 in a limiting engagement, ensuring the reliable positioning of the adjusting member 20.

[0053] In other embodiments, the base 10 and the first limiting part 31 can also be connected by a small drive motor, and the small drive motor can drive the first limiting part 31 to engage with the second limiting part 32 in a limiting engagement, or drive the first limiting part 31 to disengage from the second limiting part 32 in a limiting engagement.

[0054] In other embodiments, the elastic part 33 may also be disposed between the adjusting member 20 and the second limiting part 32.

[0055] In some embodiments, see Figure 8 and Figure 9 The base 10 has a mounting groove C2, which is open towards the adjusting member 20. A first limiting part 31 is movably disposed in the mounting groove C2. A second limiting part 32 includes a limiting groove C1, which is open towards the first limiting part 31. The first limiting part 31 extends out of the mounting groove C2 and into the limiting groove C1 to engage with the limiting groove C1. Thus, during the movement of the adjusting member 20 relative to the base 10, the adjusting member 20 can push the first limiting part 31 into the mounting groove C2, thereby preventing the first limiting part 31 from limiting the adjusting member 20. When the second limiting part 32 corresponds to the first limiting part 31, the limiting groove C1 no longer limits the first limiting part 31, allowing the first limiting part 31 to extend from the mounting groove C2 into the limiting groove C1 and engage with the second limiting part 32, thus achieving the limiting installation of the adjusting member 20.

[0056] Optionally, the first limiting part 31 can be constructed as a sphere. The limiting groove C1 can be constructed as a semi-circular groove. In this way, it is convenient for the first limiting part 31 to slide into or out of the semi-circular groove, thereby facilitating the switching of the first limiting part 31 and the second limiting part 32 to cooperate with each other or disengage from each other.

[0057] In other embodiments, the mounting groove C2 may also be formed in the base 10. The limiting groove C1 is formed in the adjusting member 20.

[0058] Optionally, the extension direction of the adjusting member 20 is parallel to the second direction Y, and the extension direction of the mounting groove C2 is parallel to the third direction Z. The first direction X, the second direction Y, and the third direction Z intersect each other.

[0059] In some embodiments, see Figure 8 and Figure 9 The base 10 has a groove C4 formed on the side facing the first adjustment surface P3. The extension direction of the groove C4 is parallel to the length direction of the adjustment member 20. The adjustment member 20 is slidably fitted into the groove C4, and the first adjustment surface P3 is in contact with the bottom surface of the groove C4. A first limiting part 31 is provided on the side of the groove C4, and a second limiting part 32 is provided on the edge of the adjustment member 20 along its width direction.

[0060] Thus, the slide groove C4 can guide the movement of the adjusting member 20. At the same time, the slide groove C4 also helps to hide the first limiting part 31 and the second limiting part 32, thereby preventing debris from falling between the first limiting part 31 and the second limiting part 32 and ensuring the reliable fit between the first limiting part 31 and the second limiting part 32.

[0061] In other embodiments, the slide groove C4 may also be provided on the first adjustment surface P3. The base 10 is provided with a slider. The slider is slidably fitted within the slide groove C4. In this way, the cooperation between the slide groove C4 and the slider can also guide the adjustment member 20.

[0062] Optionally, see Figure 8 and Figure 9 The adjustment mechanism 100 also includes a mounting part 34. The mounting part 34 has a mounting groove C2. A receiving groove C3 is provided on the side of the slide groove C4. The mounting part 34 is fixedly connected to the receiving groove C3. In this way, the first limiting part 31, the mounting part 34 and the base 10 are detachably connected, which facilitates the assembly of the mounting part 34, the first limiting part 31 and the elastic part 33 and then inserts them into the base 10, thereby improving assembly efficiency.

[0063] In some embodiments, see Figure 7 and Figure 8 The first adjusting surface P3 has an adjusting groove C5, which extends parallel to the length direction of the adjusting member 20. The base 10 has a third limiting part 35 extending towards the first adjusting surface P3 and into the adjusting groove C5. The third limiting part 35 limits the travel of the adjusting member 20 relative to the base 10. Thus, the adjustment groove C5 and the third limiting part 35 cooperate to prevent the adjusting member 20 from detaching from the base 10, ensuring that the adjusting member 20 remains mounted on the lower mold 202 or the upper mold 201 under the limiting action of the third limiting part 35.

[0064] Optionally, the adjustment groove C5 can penetrate the second adjustment surface P4 of the adjustment member 20 along the thickness direction (i.e., the first direction X), and the bottom surface of the adjustment groove C5 can also be spaced apart from the second adjustment surface P4.

[0065] In some embodiments, the third limiting portion 35 passes through the base 10 and is fixedly connected to the lower mold 202. The third limiting portion 35 can also serve to connect the base 10 and the lower mold 202. The third limiting portion 35 can be constructed as a screw or a pin.

[0066] In other embodiments, the adjustment groove C5 may also be disposed on the base 10, and the third limiting part 35 may be disposed on the adjustment member 20.

[0067] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
