[0010] Through the above technical solution, the lower molds of different sizes are fixed under the action of the adjustment mechanism, so that the mold is suitable for orthopedic steel plates of different sizes, thereby making the mold more widely used and more practical.

[0011] By combining an ejector under the lower mold, it is convenient for unloading and also enhances the functionality of the entire mold frame.

[0012] As a further improvement of the above scheme, the rising ejection unit includes cavity one, a ejector rod groove, a long rod, a clamping groove, cavity two, a buffer unit, a clamping unit and a sliding unit. The cavity one is opened in the lower mold and is connected with the outside of the lower mold to form a channel one for the long rod to move. The two ejector rod grooves are opened on the lower mold, and the lower mold at the bottom of the ejector rod groove is also provided with a groove which is connected with the ejector rod groove and cavity one to form channel two. One ends of the two long rods are fixed on the upper mold, and the other ends of the long rods are located in cavity one.

[0035] The adjusting mechanism includes an upper mold 5, a movable groove 6, a slide bar 7, a sliding sleeve block 8, an L rod 9, a fixing bolt 10, a bolt groove 11, a lower mold 12 and a rising ejection unit. The upper mold 5 is fixed on the upper mold 2, two movable grooves 6 are opened on the lower mold 1, the slide bar 7 is fixed in the movable groove 6, four sliding sleeve blocks 8 all slide on the slide bar 7, the L rod 9 is fixed on the sliding sleeve block 8, the L rod 9 is provided with a groove for the fixing bolt 10 to pass through, a plurality of bolt grooves 11 are opened on the lower mold 1 next to the movable groove 6 and can be used for the fixing bolt 10 to rotate and fix, and the lower mold 12 is placed in the middle of the lower mold 1.

[0036] The rising ejection unit includes a cavity 16, a ejector rod groove 17, a long rod 18, a clamping groove 19, a cavity 20, a buffer unit, a clamping unit and a sliding unit. The cavity 16 is opened in the lower mold 1 and is connected with the outside of the lower mold 1 to form a channel 1 for the long rod 18 to move. Two ejector rod grooves 17 are opened on the lower mold 12, and a groove is also opened on the lower mold 1 at the bottom of the ejector rod groove 17 and is connected with the ejector rod groove 17 and the cavity 16 to form a channel 2. One ends of the two long rods 18 are fixed on the upper mold 2, and the other ends of the long rods 18 are located in the cavity 16. The cavity 20 is opened at one end of the ejector 3 close to the lower mold 1, and the clamping groove 19 is opened in the long rod 18.

[0037] The implementation principle of the combined precision mold frame for medical equipment in the present application is: first, the ejector 3 is moved to the placement plate below the lower mold 1, and the lower mold 1 and the ejector 3 are fixed with bolts so that the slide rail 1 21 and the slide rail 2 22 are located on the same vertical line, and then the middle part of the lower mold 12 is placed in the middle of the lower mold 1, and the L rod 9 is pulled closer to the lower mold 12, so that the sliding sleeve 8 slides on the sliding rod 7. Until the L rod 9 fits on the lower mold 12, use two fixing bolts 10 to fix the L rod 9 and the bolt groove 11, so that the four L rods 9 are all fitted on the lower mold 12 to accurately fix the lower mold 12 on the lower mold 1, and the upper mold 5 is also fixed on the upper mold 2 in the same way (not shown in the figure), and then put the aggregate piece into the lower mold 12, and start the hydraulic cylinder 4, so that the hydraulic cylinder 4 drives the upper mold 2 to approach the lower mold 1, compresses the spring 14, and the outer cylinder 13 gradually covers the inner cylinder 15, and when the upper mold 2 approaches the lower mold 1, it drives the long rod 18 to move from the cavity 16 to the cavity 20, so that the inside of the long rod 18 gradually covers the support rod 24, and when the inner wall of the long rod 18 and the block 29 fit, the block 29 will be moved to the cavity 20 as the long rod 18 continues to move. The spring groove 27 is compressed, and the spring 28 is compressed, so that the moving block 30 slides in the moving groove 31, so that the block 29 fits the inner wall of the long rod 18. When the output end of the hydraulic cylinder 4 drives the upper mold 5 to move to the maximum value, the block 29 is stuck in the slot 19 at this time, and the upper mold 5 also completes the stamping work of the bone plate in the lower mold 12. After standing for a period of time, the hydraulic cylinder 4 is started, so that the hydraulic cylinder 4 drives the upper mold 2 and the upper mold 5 to gradually move away from the lower mold 1, and drives the long rod 18 to move from the cavity 20 to the cavity 1 16, and the outer cylinder 13 gradually moves away from the inner cylinder 15, so that the spring 14 can be stretched. When the long rod 18 moves, the block 29 is stuck in the slot 19, which will drive the support rod 24 to move, so that the slider 23 slides from the slide rail 1 21 to the slide rail 2 22. The connecting rod 25 is also pulled to move, so that the push rod 26 enters the cavity 16 through the push rod slot 17 and contacts the stamped aggregate piece. With the continuous movement of the long rod 18, the aggregate piece is pushed out from the lower mold 12, so that the aggregate piece is loose in the lower mold 12 and can be easily taken out. When the force exerted by the aggregate piece on the push rod 26 is greater than the force exerted by the spring 28 on the block 29 on the slot 19, the long rod 18 will separate from the slot 19, and under the action of the gravity potential energy, the connecting rod 25 drives the push rod 26 back from the cavity 16 to the cavity 20, thereby completing the stamping work of an aggregate piece.

Both ends of the connecting rod 25 are fixed to one end of the support rod 24. The two push rods 26 are fixed to the middle of the connecting rod 25 by bolts and are located directly below the channel 2. Two spring slots 27 are opened on the support rod 24.
