Description

Technical Field

[0001] This utility model relates to the field of shaping technology, and in particular to a shaping mold. Background Technology

[0002] Currently, stamping forming dies typically include a forming component that moves horizontally, and a driving component on the upper die. When the upper and lower dies are closed, the driving component drives the forming component to move horizontally to approach and shape the workpiece. However, this structure results in a large overall space required for the stamping forming die. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a shaping mold that can reduce the space occupied.

[0004] A shaping mold according to an embodiment of the present invention includes an upper mold and a lower mold. The upper mold has a first driving member. The lower mold includes a lower mold base, a shaping protrusion, and a shaping component. The shaping protrusion is disposed on the lower mold base and is used to support the blank. A guide block is provided on the lower mold base. The guide block is located on the horizontal side of the shaping protrusion. A guide slope is provided on the side of the guide block near the shaping protrusion. The shaping component is slidably disposed on the lower mold base in the vertical direction and is located between the shaping protrusion and the guide block. The end of the shaping component away from the shaping protrusion abuts against the guide slope. A first shaping area for accommodating the horizontal sidewall of the blank is formed between the shaping component and the shaping protrusion. Under the action of an external force, the upper mold and the lower mold can approach each other so that the first driving member pushes the shaping component downward and the shaping component moves horizontally towards the first shaping area under the action of the guide slope, so as to cooperate with the shaping protrusion to shape the horizontal sidewall of the blank.

[0005] A shaping mold according to an embodiment of the present utility model has at least the following technical effects:

[0006] In the working process of the forming mold of this application, the blank is placed on the forming protrusion, and the part to be formed is located in the first forming area. Under the action of external force, when the upper mold and the lower mold approach each other to close the mold, the first driving member can push the forming part downward along the guide slope of the guide block and horizontally approach the blank in the first forming area. Then, with the cooperation of the forming protrusion and the forming part, the side wall of the blank is formed. It can be understood that since the forming part approaches the blank in the first forming area horizontally along the guide slope, the space required for the movement of the forming part is small, thereby reducing the space occupied by the forming mold.

[0007] According to some embodiments of the present invention, a shaping mold has a guide protrusion on the guide inclined surface and a guide groove adapted to the guide protrusion on the shaping part. The guide protrusion and the guide groove are slidably engaged.

[0008] According to some embodiments of the present invention, a shaping mold further includes a first elastic reset member, which is connected to the shaping part and the lower mold base respectively, and is used to provide an elastic force to reset the shaping part upward.

[0009] According to some embodiments of the present invention, a shaping mold has a receiving hole on the lower mold base. The extending direction of the receiving hole is parallel to the extending direction of the guide inclined surface. The first elastic reset member is a spring, which is disposed in the receiving hole. The opposite ends of the spring are respectively connected to the shaping member and the hole wall of the receiving hole.

[0010] According to some embodiments of the present invention, a shaping mold has a limiting protrusion at the upper end of the guide block, which can abut against the upper end of the shaping part to limit the shaping part in the vertical direction.

[0011] According to some embodiments of the present invention, a shaping mold includes a first shaping surface on the circumferential surface of the shaping protrusion. The first shaping surface is an arc shape arranged around the guide block. The lower mold includes a plurality of shaping parts, which are arranged at intervals around the guide block and are all located between the first shaping surface and the guide block. The guide block has a plurality of guide slopes on its circumferential side, and the shaping parts correspond one-to-one with the guide slopes and are abutted against each other.

[0012] According to some embodiments of the present invention, a shaping mold includes a second shaping surface protruding outward on the circumferential surface of the shaping protrusion, and a shaping block is included in the lower mold. The shaping block is slidably disposed on the lower mold base in the horizontal direction. A second shaping area for accommodating the horizontal sidewall of the blank is formed between the shaping block and the second shaping surface. A first abutting inclined surface is provided on the side of the shaping block away from the second shaping surface. The upper mold has a second driving member. Under the action of external force, the upper mold and the lower mold can approach each other, so that the second driving member pushes the first abutting inclined surface downward and makes the shaping block horizontally approach the second shaping area to cooperate with the second shaping surface to shape the horizontal sidewall of the blank.

[0013] According to some embodiments of the present invention, a shaping mold further includes a second elastic reset member, which is connected to the shaping block and the lower mold base respectively, and is used to provide an elastic force to keep the shaping block away from the second shaping surface.

[0014] According to some embodiments of the present invention, a shaping mold includes a shaping part and an abutting part distributed along a first horizontal direction. The shaping part forms a first shaping area between one end in a second horizontal direction and a first shaping surface. The second horizontal direction is perpendicular to the first horizontal direction. One end of the abutting part in the second horizontal direction abuts against a guide slope. The lower mold also includes an abutting member, which abuts against the other end of the abutting part in the second horizontal direction and is used to prevent the shaping part from moving away from the guide slope.

[0015] According to some embodiments of the present invention, a shaping mold has a second abutting inclined surface on the abutting member. The second abutting inclined surface is arranged parallel to the guide inclined surface, and the shaping member abuts against the second abutting inclined surface.

[0032] The following is for reference. Figures 1 to 7 A shaping mold according to the first aspect of this utility model will be described in detail.

[0033] refer to Figures 1 to 5 According to an embodiment of the present invention, a shaping mold includes an upper mold 100 and a lower mold 200. The upper mold 100 has a first driving member 110. The lower mold 200 includes a lower mold base 210, a shaping protrusion 220, and a shaping member 230. The shaping protrusion 220 is disposed on the lower mold base 210 and is used to support the blank. A guide block 211 is provided on the lower mold base 210. The guide block 211 is located on the horizontal side of the shaping protrusion 220. A guide inclined surface 211a is provided on the side of the guide block 211 near the shaping protrusion 220. The shaping member 230 is slidably disposed on the lower mold base 210 in the vertical direction. The upper die 100 and the lower die 200 are located between the shaping protrusion 220 and the guide block 211. The end of the shaping member 230 away from the shaping protrusion 220 abuts against the guide slope 211a. A first shaping area for accommodating the horizontal sidewall of the blank is formed between the shaping member 230 and the shaping protrusion 220. Under the action of external force, the upper die 100 and the lower die 200 can approach each other so that the first driving member 110 pushes the shaping member 230 downward and the shaping member 230 is horizontally close to the first shaping area under the action of the guide slope 211a, so as to cooperate with the shaping protrusion 220 to shape the horizontal sidewall of the blank.

[0034] During the operation of the forming mold of this application, the blank is placed on the forming protrusion 220, and the part to be formed 231 is located in the first forming area. Under the action of external force, when the upper mold 100 and the lower mold 200 approach each other to close the mold, the first driving member 110 can push the forming member 230 downward and horizontally close to the blank in the first forming area along the guide slope 211a of the guide block 211. Then, with the cooperation of the forming protrusion 220 and the forming member 230, the side wall of the blank is shaped. It can be understood that since the forming member 230 is horizontally close to the blank in the first forming area along the guide slope 211a, the space required for the movement of the forming member 230 is small, thereby reducing the space occupied by the forming mold.

[0035] refer to Figure 4 and Figure 7 In some embodiments of this utility model, a guide protrusion 212 is provided on the guide slope 211a, and a guide groove 230a adapted to the guide protrusion 212 is provided on the shaping part 230. The guide protrusion 212 and the guide groove 230a are slidably engaged. It can be understood that by providing the guide groove 230a on the shaping part 230 and making the guide groove 230a slidably engaged with the guide protrusion 212 of the guide slope 211a, the possibility of deviation in the movement of the shaping part 230 along the guide slope 211a is reduced, thereby making the shaping of the shaping mold of this application more stable.

[0036] refer to Figure 6 In some embodiments of this utility model, the lower mold 200 further includes a first elastic reset member 240, which is connected to the shaping member 230 and the lower mold base 210 respectively, and is used to provide an elastic force to reset the shaping member 230 upward. It can be understood that under the action of external force, when the upper mold 100 and the lower mold 200 approach each other, the first driving member 110 drives the shaping member 230 to move downward along the guide slope 211a, so that the first elastic reset member 240 stores elastic potential energy. When the upper mold 100 and the lower mold 200 move away from each other, the first driving member 110 moves away from the shaping member 230, and the first elastic reset member 240 releases elastic potential energy to drive the shaping member 230 to reset upward along the guide slope 211a.

[0037] like Figure 6As shown, in some embodiments, the lower mold base 210 is provided with a receiving hole 210a, the extending direction of the receiving hole 210a being parallel to the extending direction of the guide slope 211a. The first elastic reset member 240 is a spring, which is disposed within the receiving hole 210a, with its opposite ends connected to the forming member 230 and the hole wall of the receiving hole 210a, respectively. It can be understood that by placing the spring within the receiving hole 210a, and ensuring that the extending direction of the receiving hole 210a is the same as the extending direction of the guide slope 211a, when the spring deforms under the action of the forming member 230, the extension and contraction direction of the spring is parallel to the guide slope 211a, thereby reducing the deformation of the spring in other directions and improving the service life of the spring.

[0038] like Figure 4 and Figure 6 As shown, in one embodiment, the upper end of the guide block 211 is provided with a limiting protrusion 213, which can abut against the upper end of the shaping part 230 to limit the shaping part 230 in the vertical direction. It can be understood that when the shaping part 230 is reset upward under the action of the first elastic reset member 240, the limiting protrusion 213 at the upper end of the guide block 211 can abut against the upper end of the shaping part 230, thereby restricting the shaping part 230 from disengaging from the lower mold base 210 in the vertical direction.

[0039] refer to Figure 4 and Figure 5 In some embodiments of this utility model, the circumferential surface of the shaping protrusion 220 includes a first shaping surface 221. The first shaping surface 221 is an arc shape surrounding the guide block 211. The lower mold 200 includes a plurality of shaping parts 230. The plurality of shaping parts 230 are spaced apart around the guide block 211 and are all located between the first shaping surface 221 and the guide block 211. The circumferential side of the guide block 211 is provided with a plurality of guide inclined surfaces 211a. The shaping parts 230 correspond one-to-one with the guide inclined surfaces 211a and are abutted against each other. It is understandable that, since the first shaping surface 221 is arranged around the guide block 211 and multiple shaping parts 230 are arranged at intervals around the guide block 211, the shaping parts 230 can shape the blank in the first shaping area formed between the first shaping surface 221 and the multiple shaping parts 230 horizontally along the guide slope 211a, so that the space required for the movement of the shaping parts 230 is smaller, the overall structure of the shaping mold is more compact, and thus the size of the shaping mold is reduced.

[0040] like Figure 4 and Figure 5As shown, in some embodiments, the circumferential surface of the shaping protrusion 220 further includes an outwardly protruding second shaping surface 222, and the lower die 200 further includes a shaping block 250, which is slidably disposed on the lower die base 210 in the horizontal direction. A second shaping area for accommodating the horizontal sidewall of the blank is formed between the shaping block 250 and the second shaping surface 222. A first abutting inclined surface 250a is provided on the side of the shaping block 250 away from the second shaping surface 222. The upper die 100 has a second driving member 120. Under the action of external force, the upper die 100 and the lower die 200 can approach each other so that the second driving member 120 pushes the first abutting inclined surface 250a downward and makes the shaping block 250 horizontally approach the second shaping area to cooperate with the second shaping surface 222 to shape the horizontal sidewall of the blank. Understandably, when the blank is placed on the shaping protrusion 220, under the action of external force, when the upper mold 100 and the lower mold 200 approach each other to close the mold, the second driving member 120 can abut against the first abutting inclined surface 250a to push the shaping block 250 to approach the blank in the second shaping area in the horizontal direction, and then the side wall of the blank is shaped by the cooperation of the shaping protrusion 220 and the shaping block 250.

[0041] like Figure 4 As shown, in one embodiment, the lower mold 200 further includes a second elastic reset member, which is connected to the shaping block 250 and the lower mold base 210 respectively, and is used to provide an elastic force to keep the shaping block 250 away from the second shaping surface 222. It is understood that under the action of an external force, when the upper mold 100 and the lower mold 200 approach each other, the second driving member 120 drives the shaping block 250 to move horizontally, so that the second elastic reset member stores elastic potential energy. When the upper mold 100 and the lower mold 200 move away from each other, the second driving member 120 moves away from the shaping block 250, and the second elastic reset member releases its elastic potential energy to drive the shaping block 250 horizontally away from the second shaping surface 222.

[0042] refer to Figure 4 , Figure 6 and Figure 7In some embodiments of this utility model, the shaping member 230 includes a shaping portion 231 and an abutting portion 232 distributed along a first horizontal direction. The shaping portion 231 forms a first shaping area between one end of the second horizontal direction and the first shaping surface 221. The second horizontal direction is perpendicular to the first horizontal direction. The abutting portion 232 abuts against the guide slope 211a at one end in the second horizontal direction. The lower mold 200 also includes an abutting member 260, which abuts against the other end of the abutting portion 232 in the second horizontal direction and is used to prevent the shaping member 230 from moving away from the guide slope 211a. Understandably, when the upper mold 100 and the lower mold 200 approach each other to close, the first driving member 110 can push the abutting part 232 of the shaping member 230 to move downward along the guide slope 211a of the guide block 211, so as to drive the abutting part 232 to approach and abut against the blank in the first shaping area. Since the other end of the abutting part 232 abuts against the abutting member 260 in the second horizontal direction, the lateral force on the shaping member 230 during shaping can be balanced by the abutting member 260, thereby improving the stability of the shaping member 230 during shaping.

[0043] like Figure 6 and Figure 7 As shown, in some embodiments, the abutting member 260 is provided with a second abutting slope 261, which is arranged parallel to the guide slope 211a, and the shaping member 230 abuts against the second abutting slope 261. It can be understood that when the upper mold 100 and the lower mold 200 approach each other to close the mold, the first driving member 110 can push the abutting portion 232 of the shaping member 230 downward along the guide slope 211a of the guide block 211 and the second abutting slope 261 of the abutting portion 232, so as to drive the abutting portion 232 to approach and abut against the blank in the first shaping area.
