DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0022] Please refer to Figures 1 to 3 An in-mold riveting structure includes: a bottom plate 1, both ends of the bottom plate 1 are fixedly connected with side plates 11, a base 2 is provided at the middle position of the bottom plate 1, both ends of the base 2 are provided with main sliders 21, and the outer sides of the two main sliders 21 are provided with auxiliary sliders 3; a positioning riveting mechanism, the positioning riveting mechanism includes two riveting blocks 4, the two riveting blocks 4 are respectively arranged on the two auxiliary sliders 3, the two auxiliary sliders 3 are installed and connected with working ends 41, and pre-tightening components are provided between the two riveting blocks 4 and the two auxiliary sliders 3.

[0023] In the specific implementation process, Figure 1 and Figure 3 As shown, both end side walls of the base 2 are inclined, T-shaped blocks 42 are provided on the outer walls of the two main sliders 21, and guide rail grooves 43 are provided on the both end side walls of the base 2. The two T-shaped blocks 42 are respectively arranged in the two guide rail grooves 43, and the two T-shaped blocks 42 are respectively slidably connected to the two guide rail grooves 43.

[0024] It should be noted that: the two auxiliary sliders 3 move against the two main sliders 21, so that the main sliders 21 drive the two T-shaped blocks 42 to slide stably and obliquely upward relative to the two guide grooves 43 on both sides of the base 2;

[0025] The workpiece overcomes the friction between the workpiece and the riveting block 4 and moves relative to each other. The workpiece and the working end 41 move relative to each other by a small amount, which makes the riveting area larger.

[0026] The two main slide blocks 21 can move upward longitudinally to automatically lift up the workpiece to facilitate subsequent detachment of the workpiece.

[0027] refer to Figure 1 and Figure 2 As shown, the two riveting blocks 4 are both provided with through openings, and the two working ends 41 are slidably connected to the two through openings respectively.

[0028] It should be noted that the transverse through-holes provided on the two riveting blocks 4 allow the working end 41 to pass through, and the working end 41 directly punches the workpiece, causing concave deformation on the first and second layer sides of the workpiece, ensuring that the inner layer workpiece will also be deformed.

[0029] refer to Figure 1 and Figure 2 As shown, the preload assembly includes a push rod 5, a cylindrical cavity is provided inside the auxiliary slider 3, the push rod 5 is slidably connected to the cavity wall at one end of the cylindrical cavity, one end of the push rod 5 is fixedly connected to the riveted pressure block 4, the other end of the push rod 5 is fixedly connected to the rear plate 51, and a main spring 52 is installed inside the cylindrical cavity, one end of the main spring 52 is connected to the inner wall of the cylindrical cavity, and the other end of the main spring 52 is connected to the rear plate 51.

[0030] It should be noted that: the two electric cylinders 6 are started so that their telescopic ends drive the two auxiliary slide blocks 3 to move relatively close to each other, so that the two riveting blocks 4 rivet the two sides of the workpiece at the same time;

[0031] After riveting, the two riveting blocks 4 will still move relative to the two auxiliary slide blocks 3, so as to drive the two push rods 5 to move accordingly, and the two main springs 52 will undergo elastic deformation at the same time, so as to provide a preload force in the thickness direction of the side of the workpiece.

[0032] refer to Figure 1 As shown, the two side plates 11 are fixedly connected with electric cylinders 6 , and the telescopic ends of the two electric cylinders 6 are fixedly connected with the two auxiliary slide blocks 3 .

[0033] It should be noted that: starting the two electric cylinders 6 causes their telescopic ends to drive the two auxiliary slides 3 to move relatively close to each other, so that the two riveting blocks 4 rivet the two sides of the workpiece at the same time, and the working ends 41 on the two auxiliary slides 3 move against the two sides of the workpiece, so that they can automatically punch the two ends of the workpiece.

[0034] refer to Figure 1 As shown, both ends of the bottom plate 1 are provided with limiting grooves, and the lower ends of the two auxiliary slide blocks 3 are provided with protrusions, and the two protrusions are slidably connected with the two limiting grooves respectively.

[0035] It should be noted that: starting the two electric cylinders 6 causes their telescopic ends to drive the two auxiliary slide blocks 3 to move relatively, and the two auxiliary slide blocks 3 drive the two protrusions to slide relative to the two limiting grooves to limit the moving directions of the two auxiliary slide blocks 3.

[0036] refer to Figure 1 and Figure 3As shown, both main sliders 21 are provided with embedded grooves, both embedded grooves are fixedly connected with embedded seats 7, both embedded seats 7 are slidably connected with inner support rods 71, one end of the two inner support rods 71 ​​is fixedly connected with back plates 72, and a secondary spring 73 is installed and connected between the back plate 72 and the side wall of one end of the embedded groove.

[0037] It should be noted that: by pressing the ends of the two inner support rods 71 ​​at the same time, the two inner support rods 71 ​​drive the two back plates 72 to move accordingly, and the two auxiliary springs 73 are elastically deformed, so that the two inner support rods 71 ​​retract into the embedded grooves, which is convenient for the subsequent placement of the workpiece;

[0038] The workpiece is placed on the two main slide blocks 21, and the two auxiliary springs 73 restore elastic deformation, so that the two inner support rods 71 ​​move in the opposite direction and reset. The ends of the two inner support rods 71 ​​are pressed against the inner wall of the workpiece to achieve pre-tightening and positioning of the workpiece, so as to facilitate subsequent riveting and stamping.

[0039] After the two sides of the secondary slide block 3 move outward, there is a certain gap between the bottom surface of the workpiece and the top surface of the base 2. At this time, the two secondary springs 73 play the role of supporting the workpiece. The static friction force of the two secondary springs 73 when supporting the workpiece prevents the main slide block 21 from returning downward when the workpiece has not separated from the main slide block 21.

[0040] After the workpiece is completely separated from the main slide 21 , it can be reset under the effect of gravity.

[0041] The working principle of an in-mold riveting structure provided by the utility model is as follows: the ends of the two inner support rods 71 ​​are pressed at the same time, so that the two inner support rods 71 ​​drive the two back plates 72 to move accordingly, and the two auxiliary springs 73 are elastically deformed, and the workpiece is placed on the two main sliders 21. The two auxiliary springs 73 restore the elastic deformation, so that the two inner support rods 71 ​​move in the opposite direction and reset, and the end heads of the two inner support rods 71 ​​are pressed against the inner wall of the workpiece to achieve pre-tightening and positioning of the workpiece, so as to facilitate subsequent riveting and stamping.

[0042] Start the two electric cylinders 6 so that their telescopic ends drive the two auxiliary slide blocks 3 to move relatively close to each other, so that the two riveting blocks 4 simultaneously rivet the two sides of the workpiece, and the working ends 41 on the two auxiliary slide blocks 3 move against the two sides of the workpiece, so that the two ends of the workpiece can be automatically stamped, and at the same time, the two working ends 41 slide relative to the through openings on the riveting blocks 4;

[0043] The two auxiliary slides 3 move against the two main slides 21, so that the main slides 21 drive the two T-shaped blocks 42 to slide upward stably and obliquely relative to the two guide grooves 43 on both sides of the base 2, and the workpiece overcomes the friction between the riveting block 4 and changes its relative position. The small relative displacement between the workpiece and the working end 41 presses the riveted area to a larger area. The two main slides 21 can move upward longitudinally to automatically lift the workpiece to facilitate the subsequent separation of the workpiece.
