Multiple cooling water channels are arranged in the mold frame, and the layout of the multiple cooling water channels is simple and reasonable.

[0004] A mold frame in the above-mentioned comparative document is generally optimized through the heat dissipation structure or the overall structure inside the mold frame. Under current technical conditions, the main structural material of the mold is metal, which has significant self-weight characteristics. Therefore, it is relatively simple to fix the mold in the lower mold frame. However, it is relatively inconvenient to fix and replace the mold in the upper mold frame. Utility Model Content

[0005] The purpose of the utility model is to provide a bone plate forging die with an easily disassembled die frame structure, so as to solve the problem that it is relatively easy to fix the die in the lower die frame in the above-mentioned background technology, but it is relatively inconvenient to fix and replace the die in the upper die frame.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bone plate forging die with a die frame easy-to-disassemble structure, comprising an upper die frame, directional holes, and connecting holes, wherein the directional holes are located at the four corners inside the upper die frame, and the connecting hole is located in the middle of the upper die frame;

[0007] The bottom of the upper mold frame is fixedly connected to two symmetrically distributed fixed blocks, and an upper mold plate is slidably connected between the two fixed blocks, one end of the two fixed blocks is fixedly connected to a limit strip, and one side of the limit strip is in contact with the upper mold plate;

[0008] A positioning structure for fixing the upper template in the fixed block is arranged at the connection between the fixed block and the upper template, and a lower mold frame is arranged at the bottom of the fixed block and the upper template.

[0009] Furthermore, the positioning structure is provided with a slide groove, and the slide groove is located at the top inner side of the fixed block, and three equidistantly distributed fixing holes are provided inside the slide groove, a slot is provided at the bottom of the fixing hole, and a wedge-shaped slider is slidably connected inside the slot, a moving rod is fixedly connected to one side of the wedge-shaped slider, and the moving rod passes through the fixed block, and the moving rod forms a piston structure inside the fixed block through a spring, and positioning holes are provided at both ends of the fixed block.

[0010] Furthermore, the outer end of the movement rod is fixedly connected to a fixing bar, and the top of the fixing bar is threadedly connected to a screw rod, and the outer end of the screw rod is fixedly connected to a hand wheel, and the screw rod is rotatably connected to one side of the fixing block.

[0011] Furthermore, both ends of the upper template are slidably connected with positioning sliders, and a spring is fixedly connected between the top of the positioning slider and the upper template, the lower end of the positioning slider is slidably connected to the inside of the slide groove, and the positioning slider is snap-connected to the inside of the fixing hole.

[0012] Furthermore, four positioning columns distributed in a rectangular shape are fixedly connected to the top of the lower mold frame, and a lower mold plate is fixedly connected to the top of the lower mold frame.

[0013] Furthermore, the four corners of the lower template are provided with mounting holes, and the positioning posts penetrate through the mounting holes and are slidably connected with the positioning holes.

[0014] Furthermore, two fixing grooves are provided on both sides of the bottom of the lower mold frame, and a wedge block is slidably connected inside the fixing groove, and a fixing bolt is slidably connected inside the wedge block. Two wedge grooves corresponding to the wedge blocks are provided on both sides of the bottom of the lower mold plate, and a threaded hole is provided inside the wedge groove for threaded connection with the fixing bolt.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The bone plate forging die with a die frame easy-to-disassemble structure is provided with an upper die frame, and the upper die plate is firmly clamped by two fixing blocks. During operation, the upper die plate is conveniently taken out by sliding it between the two fixing blocks. Conversely, the upper die plate is installed between the two fixing blocks until it is tightly fitted with the limit strip. This method ensures the rapid replacement of the upper die plate.

[0017] Furthermore, a positioning structure is provided. When the upper template is installed between the two fixed blocks, the positioning slider will slide inside the slide groove. In view of the fact that the side of the fixing hole is provided with a rounded edge and the slot is located at the bottom of the fixing hole, the positioning slider will smoothly slide inside the fixing hole until the upper template and the limit strip are tightly fitted. Subsequently, the wedge-shaped slider is driven to slide in the direction of the moving rod by rotating the hand wheel, so that the wedge-shaped slider is away from the bottom of the fixing hole. At this time, multiple positioning sliders will be driven by springs to slide inside the upper template until the positioning slider and the inside of the fixing hole are engaged. Finally, the lower end of the positioning slider will be located inside the slot, thereby ensuring that the upper template is firmly fixed between the two fixed blocks.

[0018] Furthermore, by passing a fixing bolt through the interior of the wedge block and fixing it to the interior of the wedge groove by means of a threaded connection, the wedge groove is firmly installed on the top of the lower mold frame. The wedge-shaped structure of the wedge block and the wedge groove enables the slope surfaces of the two to be in close contact when the wedge block moves into the wedge groove, thereby further enhancing the fixing effect of the wedge block on the lower mold plate.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In a further preferred embodiment of the present invention, Figure 1 - Figure 3 As shown, two symmetrically distributed fixed blocks 4 are fixedly connected to the bottom of the upper mold frame 1, and an upper mold plate 5 is slidably connected between the two fixed blocks 4, and one end of the two fixed blocks 4 is fixedly connected to a limit strip 6, and one side of the limit strip 6 is in contact with the upper mold plate 5; a positioning structure for fixing the position of the upper mold plate 5 inside the fixed block 4 is provided at the connection between the fixed block 4 and the upper mold plate 5, and a lower mold frame 7 is provided at the bottom of the fixed block 4 and the upper mold plate 5;

[0028] The upper template 5 is firmly clamped by two fixing blocks 4. During operation, the upper template 5 is conveniently removed by sliding it between the two fixing blocks 4. Conversely, the upper template 5 is installed between the two fixing blocks 4 until it fits tightly with the limit strip 6. This method ensures quick replacement of the upper template 5.

[0029] In a further preferred embodiment of the present invention, Figure 4 - Figure 5 As shown, the positioning structure is provided with a slide groove 11, and the slide groove 11 is located at the top of the inner side of the fixed block 4, and three equidistantly distributed fixing holes 12 are provided inside the slide groove 11, and a slot 13 is provided at the bottom of the fixing hole 12, and a wedge-shaped slider 14 is slidably connected inside the slot 13, and a moving rod 15 is fixedly connected to one side of the wedge-shaped slider 14, and the moving rod 15 runs through the inside of the fixed block 4, and the moving rod 15 forms a piston structure inside the fixed block 4 through a spring, and positioning holes 10 are provided at both ends of the fixed block 4, and a fixing bar 16 is fixedly connected to the outer end of the moving rod 15, and a screw rod 17 is threadedly connected to the top of the fixing bar 16, and a hand wheel 18 is fixedly connected to the outer end of the screw rod 17, and the screw rod 17 is rotatably connected to one side of the fixed block 4, and a positioning slider 19 is slidably connected to both ends of the upper template 5, and a spring is fixedly connected between the top of the positioning slider 19 and the upper template 5, and the lower end of the positioning slider 19 is slidably connected to the inside of the slide groove 11, and the positioning slider 19 is snap-connected to the inside of the fixing hole 12;

[0030] The hand wheel 18 is rotated to drive the screw 17 to rotate, and then the screw 17 drives the fixing bar 16 to move outside it. This action will cause the fixing bar 16 to drive the moving rod 15 to slide inside the fixing block 4, and finally the wedge-shaped slider 14 is placed in the middle position of the slot 13. In this state, the top of the wedge-shaped slider 14 will be level with the bottom of the fixing hole 12. When the upper template 5 is installed between the two fixing blocks 4, the positioning slider 19 will slide inside the slide groove 11. Since the side of the fixing hole 12 is provided with a rounded edge, and the slot 13 is located in the fixing hole 12 At the bottom of the fixing hole 12, the positioning slider 19 will smoothly slide through the fixing hole 12 until the upper template 5 is tightly fitted with the limiting strip 6. Then, the wedge-shaped slider 14 is driven to slide in the direction of the moving rod 15 by rotating the handwheel 18, so that the wedge-shaped slider 14 is away from the bottom of the fixing hole 12. At this time, multiple positioning sliders 19 will be driven by springs to slide inside the upper template 5 until the positioning slider 19 is engaged with the fixing hole 12. Finally, the lower end of the positioning slider 19 will be located inside the slot 13, thereby ensuring that the upper template 5 is firmly fixed between the two fixing blocks 4.

[0031] In a further preferred embodiment of the present invention, Figure 6 As shown, four rectangularly distributed positioning columns 8 are fixedly connected to the top of the lower mold frame 7, and a lower mold plate 9 is fixedly connected to the top of the lower mold frame 7.

Two fixing grooves 21 are provided on both sides of the bottom of the lower mold frame 7, and a wedge block 22 is slidably connected to the inside of the fixing groove 21, and a fixing bolt 23 is slidably connected to the inside of the wedge block 22. Two wedge grooves 24 corresponding to the wedge blocks 22 are provided on both sides of the bottom of the lower mold plate 9, and threaded holes are provided inside the wedge grooves 24 to be threadedly connected to the fixing bolts 23.

[0032] When the lower mold plate 9 is installed on the top of the lower mold frame 7, multiple positioning columns 8 are passed through the interior of the mounting holes 20 until the lower mold plate 9 slides through the mounting holes 20 to the top of the lower mold frame 7 and fits therewith. Subsequently, multiple wedge blocks 22 need to be slid inside the fixing grooves 21 until they are engaged with the inside of the wedge grooves 24. The wedge grooves 24 are firmly installed on the top of the lower mold frame 7 by passing the fixing bolts 23 through the interior of the wedge blocks 22 and fixing them to the inside of the wedge grooves 24 by threaded connections. The wedge-shaped structures of the wedge blocks 22 and the wedge grooves 24 enable the slopes of the two to be in close contact when the wedge blocks 22 move into the wedge grooves 24, thereby further enhancing the fixing effect of the wedge blocks 22 on the lower mold plate 9.
