Description

Technical Field

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

[0002] During the production of household appliances such as integrated boilers, it is necessary to protect the four corners of the product. Usually, the corners are formed by bending on both sides of each corner. Two sides of each corner are bent and wrapped in sequence. After the corners are wrapped, the two bent pieces need to be fixed. The traditional method is to weld them, but welding needs to be done separately, which adds an extra process, increases costs, reduces welding efficiency, and affects the appearance of the product. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a riveting molding mold that can quickly rivet two bent pieces together, thereby improving product production efficiency.

[0007] Optionally, a first wedge is provided at the bottom of the upper mold base, and a second wedge is provided at the top of the second sliding plate corresponding to the first wedge. When the upper mold base and the lower mold base are pressed together, the first wedge descends and drives the second wedge away from the workpiece placement table. When the upper mold base and the lower mold base are separated, the second wedge moves closer to the workpiece placement table under the reset action of the elastic element.

[0008] Optionally, at least two limiting rods are provided on the outer sides of each of the four corners of the workpiece placement platform to fix the workpiece.

[0009] Optionally, the workpiece placement platform is provided with multiple through holes evenly distributed, and an elastic movable rod is provided in each through hole, the elastic movable rod being connected to the lower mold base.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: By setting an elastic element in the lower die base, the insert block is pushed towards the workpiece placement table, so that the insert block and the punch below it are staggered, and the four corners of the workpiece are placed above the punch. Corresponding wedges are set at the bottom of the upper die base and the top of the lower die base. When the upper die base and the lower die base are pressed together, the elastic element is compressed under the action of the two wedges, so that the insert block moves above the punch and completes the riveting of the corners. Through the precise positioning and stamping of the die, the connection stability of the two bending pieces at the corners is improved. Attached Figure Description

[0020] Example 1 Reference Figures 1-9This embodiment provides a riveting molding mold, specifically including an upper mold base 1 and a lower mold base 2. The bottom of the upper mold base 1 is provided with a workpiece receiving cavity 3, and the top of the lower mold base 2 is provided with a workpiece placement platform 4. Both sides of the workpiece placement platform 4 are provided with stamping mechanisms 5. The stamping mechanisms 5 are used to rivet the corners of the four sides of the product. The stamping mechanism 5 includes a punch 501 and an insert block 502. The top of the insert block 502 is connected to a first sliding plate 503, which is slidably connected to the side wall of the workpiece placement platform 4. The bottom of the insert block 502 is connected to a second sliding plate 504, which is slidably connected to the lower mold base 2.

[0021] The product has two bent pieces that are folded in half at the four corners. The stamping mechanism 5 rivets and fixes the two overlapping bent pieces. The bottom of the insert block 502 has a cavity. The cavity cooperates with the punch 501 to complete the riveting process. The insert block 502 is T-shaped, and its two ends cooperate with the two punches 501 respectively.

[0022] Example 2 This embodiment provides a riveting molding mold, which differs from the first embodiment in that the workpiece placement table 4 has grooves 401 on both sides, one side of the first sliding plate 503 is located in the groove 401, and multiple springs are provided in the groove 401, with the springs connected to the first sliding plate 503.

[0023] The lower mold base 2 has a groove 201 on the top. An elastic element 202 and a slider 203 are provided in the groove 201. The end of the elastic element 202 is connected to the slider 203, and the top of the slider 203 is connected to the second sliding plate 504.

[0024] The upper mold base 1 is provided with a first wedge 6 at the bottom, and the second sliding plate 504 is provided with a second wedge 7 corresponding to the first wedge 6 at the top. When the upper mold base 1 and the lower mold base 2 are pressed together, the first wedge 6 descends and drives the second wedge 7 away from the workpiece placement table 4. When the upper mold base 1 and the lower mold base 2 are separated, the second wedge 7 moves closer to the workpiece placement table 4 under the reset action of the elastic element 202.

[0025] At least two limiting rods 8 are provided on the outer sides of the four corners of the workpiece placement platform 4 to fix the workpiece.

[0026] Multiple through holes are evenly provided on the workpiece placement table 4, and an elastic movable rod 9 is installed in the through hole. The elastic movable rod 9 is connected to the lower mold base 2.

[0027] The stamping mechanism 5 also includes a punch seat 505, with the punch 501 slidably connected to the punch seat 505. A buffer 506 is provided inside the punch seat 505, and the buffer 506 is sleeved with the punch 501.

[0028] A fixed seat 10 is provided inside the lower mold base 2. A rotating block 11 is rotatably connected inside the fixed seat 10. One end of the rotating block 11 is in contact with the bottom of the punch seat 505. A pressure rod 12 is provided at the top of the other end of the rotating block 11. A pressure block 13 corresponding to the pressure rod 12 is provided at the bottom of the upper mold base 1.

[0029] Multiple guide rods 14 are installed at the bottom of the upper mold base 1, and multiple guide sleeves 15 that cooperate with the guide rods 14 are installed at the top of the lower mold base 2.

[0030] The upper mold base 1 is connected to the top of the upper pressure plate 16, and the lower mold base 2 is connected to the bottom of the lower pressure plate 17.

[0031] The elastic element 202 is a nitrogen spring, which cooperates with the spring in the groove 401 to control the lateral sliding of the insert block 502. The elastic movable rod 9 is used to support the workpiece and prevent the workpiece from deforming during the stamping process. The bottom of the elastic movable rod 9 is connected to the lower die base 2. A spring is installed in the elastic movable rod 9, which can freely extend and retract within a certain range.

[0032] The tops of both ends of the rotating block 11 are arc-shaped. One end is in contact with the bottom of the punch seat 505, and the other end is in contact with the bottom of the pressure rod 12. The punch seat 505 and the pressure rod 12 are slidably connected to the lower die seat 2. When the rotating block 11 rotates around the center as the axis of rotation, it can drive the punch seat 505 and the pressure rod 12 to move in the vertical direction.

[0033] In use, the elastic element 202 is in its initial state, the first sliding plate 503 is in contact with the side of the workpiece placement table 4, and the insert block 502 is in a position offset from the punch 501. At this time, the workpiece is placed in the workpiece placement table 4 and fixed by multiple limit rods 8. The upper die seat 1 is pressed down. During the process, the first wedge block 6 first drives the second wedge block 7 to move outward, so that the insert block 502 moves directly above the punch 501. Then the pressure block 13 and the pressure rod 12 come into contact, thereby fixing the rotating block 11 and the punch seat 505. Finally, when the upper die seat 1 and the lower die seat 2 are pressed together, the punch 501 rivets the corner of the workpiece. During the riveting and stamping process, the buffer element 506 in the punch seat 505 plays an auxiliary buffering role for the punch 501.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
