[0023] refer to Figures 1 to 4The mold fixing device for automobile parts processing described in this embodiment includes a support base 1, a positioning groove 2 is formed at the upper end of the support base 1, a lower mold 3 is inserted into the inner side of the positioning groove 2, an upper mold 4 is provided at the upper end of the lower mold 3, and a clamping groove 5 is symmetrically provided at the upper end of the upper mold 4. A fixing mechanism 6 is provided at the inner upper end of the support base 1, and an ejection mechanism 13 is provided inside the positioning groove 2; the upper mold 4 is positioned and inserted into the lower mold 3, and a sealing structure is provided between the two.
[0024] The fixing mechanism 6 includes a first mounting groove 601, which is symmetrically arranged at the upper end of the support base 1. The inner side of the first mounting groove 601 adjacent to the upper end of the support base 1 is rotatably connected with the same bidirectional screw 602, and the outer side of the bidirectional screw 602 is threadedly connected with a movable frame 603. The end of the movable frame 603 is slidably connected to the inner side of the first mounting groove 601. A mounting cavity 605 is arranged on the inner side of the movable frame 603. The upper end of the movable frame 603 is symmetrically fixedly installed with a first electric push rod 604, and the inner side of the mounting cavity 605 is slidably connected to a limit plate 606. The output end of the first electric push rod 604 movably extends into the inner side of the mounting cavity 605 and is fixedly installed with the upper end of the limit plate 606. The lower end of the positioning plate 606 is fixedly installed with a clamping block 607, and the side of the clamping block 607 away from the limiting plate 606 is arranged on the inner side of the clamping groove 5. One end of the bidirectional screw 602 is provided with the same transmission mechanism 7, and the transmission mechanism 7 includes a second mounting groove 701. The second mounting groove 701 is opened on the right side of the support base 1, and the inner side of the second mounting groove 701 is rotatably connected with a rotating rod 705. The front side of the support base 1 is fixedly installed with a driving motor 702, one end of the rotating rod 705 passes through the groove wall of the second mounting groove 701 and is fixedly installed with the output end of the driving motor 702, and the outer side of the rotating rod 705 is fixedly installed with a first bevel gear 703, and one end of the bidirectional screw 602 extends into the inner side of the second mounting groove 701 and is fixed. A second bevel gear 704 is installed, and the first bevel gear 703 and the second bevel gear 704 are meshedly connected. When the upper mold 4 and the lower mold 3 need to be connected and fixed, the lower mold 3 is inserted into the positioning groove 2 of the support base 1, and then the upper mold 4 is installed above the lower mold 3. Then, the driving motor 702 is used to drive the rotating rod 705 to rotate in the second installation groove 701, so that the first bevel gear 703 on the rotating rod 705 meshes with the second bevel gear 704, and the bidirectional screw 602 connected to the second bevel gear 704 can rotate in the first installation groove 601. Since the two bidirectional screws 602 on the support base 1 rotate synchronously, the two movable frames 60 connected by the outer thread 3 can slide close to each other. When the movable frame 603 moves to the clamping groove 5 of the upper mold 4, the output end of the first electric push rod 604 is extended and pushed to push the limit plate 606 to slide in the installation cavity 605, so that the clamping block 607 at the lower end of the limit plate 606 can be clamped in the clamping groove 5 of the upper mold 4. Conversely, when opening, it is only necessary to move the clamping block 607 away from the clamping groove 5 and into the installation cavity 605, and then drive the motor 702 to run in the reverse direction, indirectly making the two movable frames 603 move away from each other, so that the upper mold 4 can be opened from the lower mold 3, so that the automobile parts processing mold can be quickly limited and fixed. The thread structures at both ends of the bidirectional screw 602 are opposite.
[0025] The ejection mechanism 13 includes a sink 131, which is provided at the inner bottom of the positioning groove 2. An ejection plate 132 is slidably connected to the inner side of the sink 131. A groove 133 is provided at the lower end of the support base 1. A second electric push rod 134 is symmetrically fixedly installed on the inner side of the groove 133. The output end of the second electric push rod 134 movably extends into the inner side of the sink 131 and is fixedly installed at the lower end of the ejection plate 132. When the lower mold 3 needs to be removed from the positioning groove 2 of the support base 1, it is only necessary to extend and retract the output end of the second electric push rod 134 at the groove 133 to push the ejection plate 132 to slide upward at the sink 131 of the positioning groove 2, so that the ejection plate 132 can easily eject the lower mold 3 from the positioning groove 2, thereby facilitating the removal and maintenance of the lower mold 3.
[0026] refer to Figure 2 A first sliding groove 11 is symmetrically provided on the inner side of the first mounting groove 601, and the end of the movable frame 603 is slidably connected to the first sliding groove 11. A third sliding groove 15 is symmetrically provided on the inner side of the mounting cavity 605, and the end of the limiting plate 606 is slidably connected to the inner side of the third sliding groove 15. An inner screw sleeve 12 is fixedly installed on the inner side of the movable frame 603, and the movable frame 603 is threadedly connected to the bidirectional screw 602 through the inner screw sleeve 12. By sliding the movable frame 603 at the first sliding groove 11 of the first mounting groove 601, the stability of the movable frame 603 can be further improved. By sliding the limiting plate 606 at the third sliding groove 15 inside the mounting cavity 605, the stability of the limiting plate 606 sliding in the mounting cavity 605 can be guaranteed.
[0027] refer to Figure 1 A baffle 8 is fixed on the right side of the support base 1 by screws. The baffle 8 covers the notch of the second mounting groove 701. By using the baffle 8 on the right side of the support base 1, the transmission mechanism 7 components inside the second mounting groove 701 can be conveniently protected.
[0028] refer to Figure 2 A second slide groove 14 is symmetrically opened on the inner side of the sink 131, one end of the second slide groove 14 extends to the positioning groove 2, and the end of the ejector plate 132 and the second slide groove 14 are slidably connected. The ejector plate 132 slides at the second slide groove 14 of the sink 131 to ensure the stability of the vertical lifting of the ejector plate 132.
[0029] refer to Figure 2 The support base 1 is symmetrically fixedly connected with a fixing block 10, and a fixing hole 9 is opened on the inner side of the fixing block 10. The fixing block 10 with the fixing hole 9 can be used to facilitate the installation and fixation of the support base 1.
[0030] Principle and advantages of use: During use, the support base 1 can be conveniently installed and fixed using the fixing block 10 with the fixing hole 9. When the upper mold 4 and the lower mold 3 need to be connected and fixed, the lower mold 3 is inserted into the positioning groove 2 of the support base 1, and then the upper mold 4 is installed above the lower mold 3. Subsequently, the driving motor 702 is used to drive the rotating rod 705 to rotate in the second installation groove 701, so that the first bevel gear 703 on the rotating rod 705 engages with the second bevel gear 704 to transmit the second bevel gear, and the bidirectional screw 602 connected to the second bevel gear 704 can rotate in the first installation groove 601. Since the two bidirectional screws 602 on the support base 1 rotate synchronously, the two movable racks 603 connected by the outer thread can slide close to each other. When the movable rack 603 moves to the clamping groove 5 of the upper mold 4, the output end of the first electric push rod 604 is extended and retracted to push the limit plate 606 to slide in the installation cavity 605, so that the clamping block 607 at the lower end of the limit plate 606 can be clamped in the clamping groove 5 of the upper mold 4.
[0031] When disassembling and opening, it is only necessary to move the clamping block 607 away from the clamping groove 5 and put it into the installation cavity 605, and then drive the motor 702 to run in the reverse direction, indirectly making the two movable frames 603 move away from each other, so that the upper mold 4 can be easily opened from the lower mold 3. When removing the lower mold 3 from the positioning groove 2 of the support base 1, it is only necessary to push the ejection plate 132 to slide upward at the sinking groove 131 of the positioning groove 2 through the output end of the second electric push rod 134 at the groove 133, so that the ejection plate 132 can easily eject the lower mold 3 from the positioning groove 2.
