[0011] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0012] Embodiment 1:

[0013] like Figure 1-Figure 3As shown, the utility model discloses a clamping and fixing device for mold frame processing, including a base 1, a fixing platform 2 is concavely provided on the upper side of the base 1, the fixing platform 2 can be a rectangular structure, and the four side walls of the base 1 are respectively provided with a fixing device; the fixing device includes two screw sleeves 3 arranged perpendicularly to the side walls of the base 1, the two screw sleeves 3 are respectively located on one side of the rectangular platform 2, and there is a gap between the two, the base 1 is a rectangular structure, the screw sleeve 3 penetrates the side wall of the base 1 and extends to the range of the fixing platform 2, a fixing rod 4 is arranged inside the screw sleeve 3, and a thread is arranged on the surface of the fixing rod 4, so that The fixing rod 4 is threadedly connected with the screw sleeve 3, and a worm gear 5 is sleeved on one end of the fixing rod 4 located outside the base 1. The worm gear 5 is slidably connected with the fixing rod 4. A slide groove 11 is axially provided at one end of the fixing rod 4, and a slider 12 is radially protruded on the inner wall of the worm gear 5. The slider 12 and the inner wall of the worm gear 5 are an integral structure. The slider 12 is embedded in the slide groove 11 to connect the worm gear 5 and the fixing rod 4 and limit the relative rotation of the worm gear 5 and the fixing rod 4. The worm wheel 5 drives the fixing rod 4 to rotate through the slider 12 and the slide groove 11, and the fixing rod 4 can be axially displaced relative to the worm gear 5. The worm wheel 5 is rotatably connected to the base 1, and a connecting sleeve 13 is arranged on the worm wheel 5. The connecting sleeve 13 is rotatably connected to the base 1, and the connecting sleeve 13 can be sleeved on the outside of the fixing rod 4, so that the worm wheel 5 and the base 1 can only rotate relative to each other, and the worm wheel 5 cannot be axially displaced. A worm 6 is vertically arranged on one side of the worm wheel 5, and the worm 6 is actually also rotatably connected to the base 1, and the base 1 is used as an assembly carrier. A motor 7 is arranged on the side wall of the base 1 at one end of the worm 6, and the output shaft of the motor 7 is connected to the worm. One end of the rod 6 is connected, the motor 7 drives the worm 6 to rotate, the worm 6 drives the worm wheel 5 to rotate, the worm wheel 5 drives the fixed rod 4 to rotate, and the fixed rod 4 moves along the thread of the screw sleeve 3 toward the fixed platform 2 until it contacts the mold frame. Because of the self-locking structure of the worm wheel 5 and worm 6, the fixed rod 4 fixes the mold frame more stably; when fixing the mold frame, the fixed rods 4 of the fixing devices on the four sides of the base 1 provide eight supporting points for the mold frame, and the fixed rods 4 at each supporting point are independent of each other and can support irregular surfaces.

[0014] When the fixing rod 4 extends out of the screw sleeve 3 for a long time and the end of the fixing rod 4 abuts against the inclined surface of the mold frame, the fixing rod 4 is easy to bend along the inclined surface, which can easily cause the fixing rod 4 to deform, thereby affecting the normal operation of the equipment and the fixing stability of the mold frame. In order to reinforce the fixing rod 4, a slide rail 8 is sunken at the bottom side of the fixing platform 2, and the slide rail 8 is in the same axial direction as the fixing rod 4. A limit plate 9 is slidably provided on the slide rail 8, and the limit plate 9 is slidably connected to the fixing rod 4. A through hole is provided on the limit plate 9, and the fixing rod 4 passes through the through hole, and the outer diameter of the fixing rod 4 is substantially consistent with the inner diameter of the through hole. A cylinder 10 is provided on the side wall of the limit plate 9 close to the fixing rod 4, and the telescopic end of the cylinder 10 is connected to the limit plate 9. When fixing the mold frame, the cylinder 10 pushes the limit plate 9 along the slide rail 8 until one side of the limit plate 9 contacts the mold frame, thereby fixing the part of the fixing rod 4 that is against the mold frame, reducing the probability of bending of the fixing rod 4 due to the inclined surface, and fixing and reinforcing the fixing rod 4.

[0015] The slide rail 8 is a dovetail slide rail 8, which can provide a greater stabilizing force to the limit plate 9, so that the displacement of the limit plate 9 on the slide rail 8 is more reliable, and the limit plate 9 will not be displaced upward.
