[0021] like Figure 1-3 As shown, a special tooling fixture for processing the joint surface of a glass mold into a preliminary mold includes a fixed base 1, an intermediate seat 4 is installed in the middle position of the fixed base 1, and intermediate baffles 7 are installed on the left and right end surfaces of the intermediate seat 4. Both ends of the fixed base 1 are slidably installed with sliding seats 8 in the left and right directions, and the sliding seats 8 are installed with vertical plates 2.

[0022] A hydraulic cylinder 10 is installed in the middle of the outer wall of the vertical plate 2, and the top rod of the hydraulic cylinder 10 is connected to the pressure plate 11. Specifically, the pressure plate 11 is an inverted L-shaped structure. The pressure plate 11 is slidably connected to the pressure rod 12 in a longer section, and the other end of the pressure rod 12 is against the end surface of the mold workpiece 5, so that the other end surface of the mold workpiece 5 can be tightly fitted on the middle baffle 7, and the leveling and positioning of the mold workpiece 5 is automatically completed. The end of the pressure rod 12 located in the pressure plate 11 is sleeved with a pressure rod spring 13, one end of the pressure rod spring 13 is against the pressure plate 11, and the other end is against the pressure rod 12. Specifically, the pressure cylinder 10 is started, and its push rod drives the pressure plate 11 to move toward the direction of the mold workpiece 5, at which time it drives the pressure rod 12 to move together, and the pressure rod spring 13 is compressed to clamp the mold workpiece 5; when releasing the clamping, the hydraulic cylinder 10 is started to drive the pressure plate 11 to reset, and under the action of the pressure rod spring 13, the pressure rod 13 is reset to release the clamping effect on the mold workpiece 5.

[0023] The top of the intermediate seat 4 and the vertical plate 2 are both equipped with positioning bars 6, which respectively press down the upper planes of the two ends of the mold workpiece 5, and cooperate with the V-shaped block 3 to fix the mold workpiece 5. The positioning bars 6 have various sizes to facilitate balancing and positioning of the joint part with the mold workpiece 5.

[0024] A sliding block 26 that can slide left and right is installed in the middle position of the sliding seat 8 and the middle seat 4, a V-shaped block seat 14 is installed on the sliding block 26, and V-shaped blocks 3 symmetrically distributed front and back are installed on the V-shaped block seat 14, a hydraulic push rod 15 is installed at the bottom center of the V-shaped block seat 14, and a hydraulic oil cylinder 2 18 is installed behind the V-shaped block seat 14, and the hydraulic oil cylinder 2 18 is connected to the hydraulic push rod 15 through the oil channel 16, and an oil circuit board 19 is installed on the outside of the hydraulic oil cylinder 2 18. The oil pressure generated by the hydraulic oil cylinder 2 18 applies pressure to the hydraulic push rod 15 through the oil channel 16, and the hydraulic push rod 15 can drive the V-shaped block seat 14 and the V-shaped block 3 to move up and down through pressurization and pressure relief.

[0025] A self-locking seat 22 is installed in front of the V-shaped block seat 14, and a self-locking block 21 is installed on the self-locking seat 22 against the side wall of the V-shaped block seat 14. The self-locking block 21 has a locking function on the slide rail. A pressure relief unlocking pull rod 23 and a pull rod head 24 are installed on the end of the self-locking seat 22 away from the self-locking block 21. When the oil pressure switch is pulled down and the lock of the sliding block 26 cannot be released, the locking and release of the self-locking block can be controlled by the pressure relief pull rod, so that the sliding block 26 can move left and right on the slide rail.

[0031] The process of clamping the mold workpiece of the utility model is as follows:

[0032] First, select a V-shaped block 3 of appropriate size, place the mold workpiece 5 horizontally on the V-shaped block 3, and turn the oil pressure switch upward to make the mold workpiece 5 rise to a position where the upper plane of the mold is in close contact with the lower plane of the positioning bar 6 installed on the vertical plate 2 and the middle seat 4 respectively;

[0033] Then, the positioning bars 6 on the top of the middle seat 4 and the vertical plate 2 respectively press down the upper planes at both ends of the mold workpiece 5, and cooperate with the V-shaped block 3 to fix the mold workpiece 5;

[0034] Finally, the pressing cylinder 10 is started, and its push rod drives the pressure plate 11 to move toward the direction of the mold workpiece 5, and at this time drives the pressure rod 12 to move together, and the pressure rod spring 13 is compressed. The pressure rod 12 applies pressure to the end face of the mold workpiece 5 clamped on the V-block 3 and pressed by the positioning strip 6, so that the other end face of the mold workpiece 5 can fit tightly on the middle baffle 7, and the leveling and positioning of the mold workpiece 5 is automatically completed.
