Description

Technical Field

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

[0002] A convex hull forming die typically includes a driving component and a punching component. The driving component drives the punching component to punch the surface of the workpiece to be punched. However, existing convex hull forming dies can only punch a single side of the workpiece. If punching is required on both sides of the workpiece, it needs to be done in two steps, making the punching process more complicated. 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 convex bulge forming die capable of simultaneously punching two sides of a workpiece.

[0004] A convex bulge forming 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, a second driving member, and a third driving member. The lower mold includes a lower mold base, a first punching member, a second punching member, a first abutting member, and a second abutting member. The first abutting member, the first punching member, the second punching member, and the second abutting member are sequentially spaced along a first horizontal direction and are all slidably disposed on the lower mold base along the first horizontal direction. A first abutting inclined surface and a second abutting inclined surface are respectively provided on the side of the first punching member and the second punching member that are close to each other. The receiving part and the second abutting part are respectively provided with a third abutting slope and a fourth abutting slope on the opposite side; wherein, under the action of external force, the upper die and the lower die can approach each other, so that the first driving part and the second driving part push the first punching part and the first abutting part closer to each other through the first abutting slope and the third abutting slope respectively, so as to punch and form a first protrusion on the workpiece, and the first driving part and the third driving part push the second punching part and the second abutting part closer to each other through the second abutting slope and the fourth abutting slope respectively, so as to punch and form a second protrusion on the workpiece.

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

[0006] During the use of the convex bulge forming mold of this application, under the action of external force, the upper mold presses down on the lower mold. The first driving member simultaneously contacts the first abutting inclined surface and the second abutting inclined surface, and pushes the first punching member and the second punching member away from each other through the first abutting inclined surface and the second abutting inclined surface, respectively. At the same time, the second driving member contacts the third abutting inclined surface, and pushes the first abutting member to slide towards the first punching member through the third abutting inclined surface, so that the first abutting member and the first punching member cooperate to punch and form the first convex bulge on one side wall of the workpiece in the first horizontal direction. At the same time, the third driving member contacts the fourth abutting inclined surface, and pushes the second abutting member to slide towards the second punching member through the fourth abutting inclined surface, so that the second abutting member cooperates with the second punching member to punch and form the first convex bulge on the other side wall of the workpiece in the first horizontal direction. As can be seen from the above usage process, this application drives the first punching part and the second punching part to move through the first driving part, so that the first punching part cooperates with the first abutting part to punch, and the second punching part cooperates with the second abutting part to punch. This can complete the bidirectional convex hull forming in a single punching, which significantly improves the stamping efficiency and avoids the positioning error that may occur in step-by-step punching.

[0007] According to some embodiments of the present invention, a convex bulge forming mold includes a lower mold further comprising a positioning member for positioning the workpiece. The positioning member is provided with an insertion hole. When the upper mold approaches the lower mold, the first driving member passes through the insertion hole and abuts against the first abutting inclined surface and the second abutting inclined surface.

[0008] According to some embodiments of the present invention, a convex bulge forming mold has two guide grooves distributed along a first horizontal direction on the positioning member, and the first punching member and the second punching member are respectively slidably disposed in the two guide grooves.

[0009] According to some embodiments of the present invention, a convex bulge forming mold has a positioning element that is detachably mounted on the lower mold base.

[0010] According to some embodiments of the present invention, a convex forming mold includes a first punching part and a sliding part. The punching part is connected to one end of the sliding part near the second punching part, and a first abutting inclined surface is provided on the punching part.

[0011] According to some embodiments of the present invention, a convex forming mold includes a first abutting member comprising an elastic buffer, an abutting portion, and a movable portion. The abutting portion is connected to the movable portion via the elastic buffer. The elastic buffer provides elastic force to the abutting portion away from the movable portion. The abutting portion is used to cooperate with the first punching member for punching. A third abutting inclined surface is provided on the movable portion.

[0012] According to some embodiments of the present invention, a convex forming mold has a first protrusion on the side of the first punching member away from the second punching member, a second protrusion on the side of the second punching member away from the first punching member, a first clearance groove on the side of the first abutment member near the first punching member, the first protrusion being able to extend into the first clearance groove, and a second clearance groove on the side of the second abutment member near the second punching member, the second protrusion being able to extend into the second clearance groove.

[0013] According to some embodiments of the present invention, a convex forming mold has a plurality of first protrusions on the side of the first punching member away from the second punching member, and a plurality of first clearance grooves on the side of the second abutting member close to the first punching member, with the first protrusions and the first clearance grooves being provided in a one-to-one correspondence.

[0014] According to some embodiments of the present invention, a convex forming mold includes a lower mold further comprising a first elastic reset member, which is connected to a first punching member and a lower mold base respectively. The lower mold base can provide the first punching member with an elastic force close to the second punching member.

[0015] According to some embodiments of the present invention, a convex forming mold includes a lower mold further comprising a second elastic reset member, which is connected to a first abutting member and a lower mold base respectively. The lower mold base can provide the first abutting member with an elastic force away from the first punching member.

[0033] The following is for reference. Figures 1 to 7 A convex bulge forming mold according to an embodiment of the present utility model will be described in detail.

[0034] refer to Figures 1 to 5 According to an embodiment of the present invention, a convex bulge forming mold includes an upper mold 100 and a lower mold 200. The upper mold 100 has a first driving member 110, a second driving member 120, and a third driving member 130. The lower mold 200 includes a lower mold base 210, a first punching member 220, a second punching member 230, a first abutting member 240, and a second abutting member 250. The first abutting member 240, the first punching member 220, the second punching member 230, and the second abutting member 250 are sequentially spaced along a first horizontal direction and are all slidably disposed on the lower mold base 210 along the first horizontal direction. The first punching member 220 and the second punching member 230 are respectively provided with a first abutting inclined surface 220a and a second abutting inclined surface 230a on the side of the first punching member 220 and the second punching member 230. 40 and the side opposite to the second abutting member 250 are respectively provided with a third abutting slope 240a and a fourth abutting slope 250a; wherein, 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 and the second driving member 120 respectively push the first punching member 220 and the first abutting member 240 to approach each other through the first abutting slope 220a and the third abutting slope 240a, so as to punch and form a first protrusion 310 on the workpiece 300, and the first driving member 110 and the third driving member 130 respectively push the second punching member 230 and the second abutting member 250 to approach each other through the second abutting slope 230a and the fourth abutting slope 250a, so as to punch and form a second protrusion 320 on the workpiece 300.

[0035] During the use of the convex bulge forming mold of this application, under the action of external force, the upper mold 100 presses down on the lower mold 200. The first driving member 110 simultaneously contacts the first abutting inclined surface 220a and the second abutting inclined surface 230a, and pushes the first punching member 220 and the second punching member 230 away from each other through the first abutting inclined surface 220a and the second abutting inclined surface 230a respectively. At the same time, the second driving member 120 contacts the third abutting inclined surface 240a, and pushes the first abutting member 240 towards the first punching member through the third abutting inclined surface 240a. The cutting piece 220 slides so that the first abutting piece 240 and the first punching piece 220 cooperate to punch a first protrusion 310 on one side wall of the workpiece 300 in the first horizontal direction. At the same time, the third driving member 130 contacts the fourth abutting inclined surface 250a and pushes the second abutting piece 250 towards the second punching piece 230 through the fourth abutting inclined surface 250a, so that the second abutting piece 250 cooperates with the second punching piece 230 to punch a first protrusion 310 on the other side wall of the workpiece 300 in the first horizontal direction. As can be seen from the above usage process, this application drives the first punching piece 220 and the second punching piece 230 to move by the first driving member 110, so that the first punching piece 220 cooperates with the first abutting piece 240 to punch, and the second punching piece 230 cooperates with the second abutting piece 250 to punch, which can complete the bidirectional protrusion forming in a single punching, significantly improving the stamping efficiency and avoiding the positioning errors that may occur in step-by-step punching.

[0036] Specifically, the first horizontal direction is the left and right direction.

[0037] refer to Figure 3 and Figure 4 In some embodiments of this utility model, the lower die 200 further includes a positioning member 260, which is used to position the workpiece 300. The positioning member 260 is provided with an insertion hole 260a. When the upper die 100 approaches the lower die 200, the first driving member 110 passes through the insertion hole 260a and abuts against the first abutting inclined surface 220a and the second abutting inclined surface 230a. It can be understood that by providing a positioning member 260 on the lower die 200, and the positioning member 260 is provided with an insertion hole 260a, when the upper die 100 is pressed down, the first driving member 110 passes through the insertion hole 260a and accurately abuts against the first and second abutting inclined surfaces 230a. The movement trajectory of the driving member is guided by the insertion hole 260a, ensuring the accuracy of the punching force direction and improving the consistency of the convex forming.

[0038] Specifically, workpiece 300 is mounted on positioning component 260 to achieve product positioning.

[0039] like Figure 3 and Figure 4As shown, in some embodiments, the positioning member 260 is provided with two guide grooves 260b distributed along a first horizontal direction, and the first punching member 220 and the second punching member 230 are slidably disposed in the two guide grooves 260b respectively. It can be understood that by providing two guide grooves 260b along the first horizontal direction on the positioning member 260, the guide grooves 260b can guide the first punching member 220 and the second punching member 230 to slide in the left-right direction, and the groove walls of the guide grooves 260b can limit the offset of the first punching member 220 and the second punching member 230 in the front-back direction, thereby improving the punching accuracy of the mold of this application.

[0040] In one embodiment, the positioning member 260 is detachably mounted on the lower mold base 210. For example, as... Figure 3 As shown, the lower die 200 also includes a threaded connector, and the positioning component 260 is connected to the lower die base 210 through the threaded connector. It is understood that, according to the specifications of the workpiece 300, the operator can replace the corresponding positioning component 260 on the lower die base 210, so that the die of this application can complete the punching and forming of the protrusion on the workpiece 300 of different specifications, thereby improving the versatility of the die of this application.

[0041] In some embodiments, the first punching member 220 includes a punching portion 221 and a sliding portion 222. The punching portion 221 is connected to one end of the sliding portion 222 near the second punching member 230, and the punching portion 221 is provided with a first abutting inclined surface 220a. For example, as Figure 4 As shown, the right end face of the sliding part 222 is connected to the left end face of the second punching part 230, and the punching part 221 is provided with a first abutting inclined surface 220a. It can be understood that by providing the sliding part 222 at the right end of the punching part 221, the contact area between the first punching part 220 and the lower die base 210 is increased, thereby making the first punching part 220 more stable during the sliding process in the left and right direction.

[0042] refer to Figure 4 , Figure 6 and Figure 7In some embodiments of this utility model, the first abutting member 240 includes an elastic buffer, an abutting portion 241, and a movable portion 242. The abutting portion 241 is connected to the movable portion 242 through the elastic buffer. The elastic buffer provides an elastic force to the abutting portion 241 away from the movable portion 242. The abutting portion 241 is used to cooperate with the first punching member 220 for punching. The movable portion 242 is provided with a third abutting inclined surface 240a. It can be understood that since the abutting portion 241 and the movable portion 242 are connected by the elastic buffer, when the abutting portion 241 cooperates with the first punching member 220 for punching under the drive of the movable portion 242, the elastic buffer can play a buffering role to reduce the probability of deformation of the workpiece 300 caused by hard impact. This allows the mold of this application to still complete the punching of the workpiece 300 normally when facing a workpiece 300 with a small thickness.

[0043] refer to Figure 4 , Figure 6 and Figure 7 In some embodiments of this utility model, the first punching member 220 is provided with a first protrusion 220b on the side opposite to the second punching member 230, the second punching member 230 is provided with a second protrusion 230b on the side opposite to the first punching member 220, the first abutting member 240 is provided with a first clearance groove 240b on the side near the first punching member 220, and the second abutting member 250 is provided with a second clearance groove 250b on the side near the second punching member 230. It is understood that when the first driving member 110 and the second driving member 120 push the first punching member 220 and the first abutting member 240 closer to each other via the first abutting slope 220a and the third abutting slope 240a respectively, the first protrusion 220b of the first punching member 220 is embedded in the first clearance groove 240b of the first abutting member 240, so as to punch and form a first protrusion 310 on the side of the workpiece 300 between the first punching member 220 and the first abutting member 240; when the first driving member 110 and the third driving member 130 push the second punching member 230 and the second abutting member 250 closer to each other via the second abutting slope 230a and the fourth abutting slope 250a respectively, the second protrusion 230b of the second punching member 230 is embedded in the second clearance groove 250b of the second abutting member 250, so as to punch and form a second protrusion 320 on the other side of the workpiece 300 between the second punching member 230 and the second abutting member 250. The first protrusion 310 is punched out by the cooperation of the first protrusion 220b and the first clearance groove 240b, which can reduce the excessive deformation of the first protrusion 310 in the lateral direction and improve the stability of the formation process of the first protrusion 310; the second protrusion 320 is punched out by the cooperation of the second protrusion 230b and the second clearance groove 250b, which can reduce the excessive deformation of the second protrusion 320 in the lateral direction and improve the stability of the formation process of the second protrusion 320.

[0044] In some embodiments, the first punching member 220 has a plurality of first protrusions 220b on its side away from the second punching member 230, and the second abutment member 250 has a plurality of first clearance grooves 240b on its side near the first punching member 220. The first protrusions 220b and the first clearance grooves 240b are provided in a one-to-one correspondence. For example, as Figure 6 and Figure 7 As shown, the first punching member 220 has two first protrusions 220b symmetrically arranged along the front-back direction on the side away from the second punching member 230, and the second abutting member 250 has two first clearance grooves 240b on the side near the first punching member 220. The first protrusions 220b and the first clearance grooves 240b are arranged in a one-to-one correspondence. It can be understood that by setting multiple first protrusions 220b and multiple first clearance grooves 240b, multiple first protrusions 310 on the workpiece 300 can be formed in a single punching.

[0045] It should be noted that the specific structure of the first punching part 220 is the same as that of the second punching part 230, and the specific structure of the second abutting part 250 is the same as that of the first abutting part 240.

[0046] refer to Figure 3 and Figure 4 In some embodiments of this utility model, the lower die 200 further includes a first elastic reset member, which is connected to the first punching member 220 and the lower die base 210 respectively. The lower die base 210 can provide the first punching member 220 with an elastic force to approach the second punching member 230. It can be understood that when the first driving member 110 pushes the first punching member 220 to the left through the first abutting inclined surface 220a, the first elastic reset member stores elastic potential energy. When the first driving member 110 leaves the first abutting inclined surface 220a, the first elastic reset member releases the elastic potential energy, so that the first punching member 220 moves to the right and approaches the second punching member 230. At this time, the first punching member 220 exits the first protrusion 310, so that the workpiece 300 can smoothly disengage from the lower die 200.

[0047] In some embodiments of this utility model, the lower die 200 further includes a third elastic reset member, which is connected to the second punching member 230 and the lower die base 210 respectively. The lower die base 210 can provide the second punching member 230 with an elastic force to approach the first punching member 220. It can be understood that when the first driving member 110 pushes the second punching member 230 to move to the right through the second abutting inclined surface 230a, the third elastic reset member stores elastic potential energy. When the first driving member 110 leaves the second abutting inclined surface 230a, the third elastic reset member releases the elastic potential energy, so that the second punching member 230 moves to the left and approaches the first punching member 220. At this time, the second punching member 230 exits the second protrusion 320, so that the workpiece 300 can smoothly disengage from the lower die 200.

[0048] refer to Figure 3 and Figure 4 In some embodiments of this utility model, the lower die 200 further includes a second elastic reset member, which is connected to the first abutment member 240 and the lower die base 210 respectively. The lower die base 210 can provide the first abutment member 240 with an elastic force to move away from the first punching member 220. It can be understood that when the second driving member 120 pushes the first abutment member 240 to move to the right through the third abutment inclined surface 240a, the second elastic reset member stores elastic potential energy. When the second driving member 120 leaves the third abutment inclined surface 240a, the second elastic reset member releases the elastic potential energy, so that the first abutment member 240 moves to the left away from the first punching member 220. At this time, the activity space between the first abutment member 240 and the first punching member 220 increases, and the workpiece 300 can more smoothly detach from the lower die 200.

[0049] In some embodiments of this utility model, the lower die 200 further includes a fourth elastic reset member, which is connected to the second abutment 250 and the lower die base 210 respectively. The lower die base 210 can provide the second abutment 250 with an elastic force to move away from the second punching member 230. It can be understood that when the third driving member 130 pushes the second abutment 250 to the left through the fourth abutment inclined surface 250a, the fourth elastic reset member stores elastic potential energy. When the third driving member 130 leaves the fourth abutment inclined surface 250a, the fourth elastic reset member releases the elastic potential energy, so that the second abutment 250 moves away from the second punching member 230 to the right. At this time, the activity space between the second abutment 250 and the second punching member 230 increases, and the workpiece 300 can more smoothly detach from the lower die 200.

[0050] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
