[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] 1. To facilitate the processing and positioning of the mold, the staff first place the mold into the slot opened on the base table. There are two groups of baffles and the first springs arranged inside the base table. Under the elasticity of the two groups of first springs, the two groups of baffles are pushed to tightly adhere to both sides of the lower mold respectively. After the preliminary positioning of the lower mold, the first electric push rod is started. The first electric push rod expands and contracts to drive the groove plate to move closer to the mold, and at the same time drives the sliding sleeve to slide on the guiding column, ensuring the stability of the movement. Finally, the first motor is started, so that the first motor drives the bidirectional screw to rotate through the output shaft.

The first threaded sleeve and the second threaded sleeve drive the two side clamping blocks to move respectively. And there are four groups of side clamping blocks arranged on the base table. The four sides of the upper mold and the lower mold are limited by the four groups of side clamping blocks, reducing the cumbersome manual operation and improving the accuracy of positioning.

[0014] 2. To further enhance the positioning effect, start the second electric push rod. The second electric push rod expands and contracts to push the movable plate to move closer to the upper mold. Start the second motor. The second motor drives the one-way stud to rotate through the output shaft. The one-way stud drives the screw block to move downward. The screw block drives the mounting plate to move downward, so that the movable plate moves above the upper mold. Utilize the elasticity of the second spring to make the long telescopic column on the telescopic block push the pressing block to abut against the top of the upper mold. The two pressing blocks limit and clamp the upper mold, avoiding vertical offset and shaking of the upper mold. At the same time, the second spring and the telescopic block provide a buffering effect to prevent damage to the mold and further enhance the positioning effect on the mold.

An electric push rod 2 7 is installed on the installation plate 201 through a fastener. One end of the electric push rod 2 7 is fixedly provided with a movable plate 801. A pressing block 202 is installed below the movable plate 801. A telescopic block 805 is fixedly provided between the upper end of the pressing block 202 and the movable plate 801.

[0024] During use, in order to facilitate the machining and positioning of the mold, the staff first place the mold into the notch opened on the base table 1. There are two groups of baffles 301 and first springs 302 arranged inside the base table. Under the elasticity of the two groups of first springs 302, the two groups of baffles 301 are pushed to closely adhere to both sides of the lower mold 4 respectively. After the preliminary positioning of the lower mold 4, the first electric push rod 5 is started. The first electric push rod 5 expands and contracts to push the groove plate 102 to move closer to the mold, and at the same time drives the sliding sleeve 303 to slide on the guiding column 101, ensuring the stability of the movement. Finally, the first motor 6 is started, so that the first motor 6 drives the bidirectional screw rod 106 to rotate through the output shaft. Then, the bidirectional screw rod 106 drives the two groups of threaded sleeves to move relatively through its left-handed and right-handed threads. The first threaded sleeve 104 and the second threaded sleeve 105 drive the two groups of side clamping blocks 103 to move respectively. And there are four groups of side clamping blocks 103 arranged on the base table 1. The four sides of the upper mold 3 and the lower mold 4 are limited by the four groups of side clamping blocks 103, reducing the tediousness of manual operation and improving the accuracy of positioning.

[0025] In this embodiment, a second spring 804 is arranged on the telescopic block 805.

[0026] During use, in order to further enhance the positioning effect, the second electric push rod 7 is started. The second electric push rod 7 expands and contracts to push the movable plate 801 to move closer to the upper mold 3. The second motor 803 is started. The second motor 803 drives the unidirectional stud 203 to rotate through the output shaft. The unidirectional stud 203 drives the screw block 8 to move downward. The screw block 8 drives the mounting plate 201 to move downward, so that the movable plate 801 moves above the upper mold 3. Utilizing the elasticity of the second spring 804, the long telescopic column on the telescopic block 805 pushes the pressing block 202 to abut against the top of the upper mold 3. The two groups of pressing blocks 202 limit and clamp the upper mold 3, avoiding the vertical offset and shaking of the upper mold 3. At the same time, the second spring 804 and the telescopic block 805 provide a buffering effect, preventing damage to the mold and further enhancing the positioning effect on the mold.

[0028] During use, two groups of baffles 301 and first springs 302 are installed in the notches formed in the base table. By pulling the two groups of first springs 302, the elasticity of the two groups of first springs 302 is utilized to make the two groups of baffles 301 press against both sides of the lower die 4 respectively, thereby preliminarily positioning the lower die 4 and enhancing the positioning effect.

[0029] In this embodiment, a first spring 302 is fixedly arranged between one end of the baffle 301 and the inner wall of the inner groove 806. A one-way stud 203 is installed inside the top frame 2.

The end of the one-way stud 203 away from the second motor 803 is connected to the inside of the top frame 2 through a rotating shaft.

[0030] During use, with the cooperation of a plurality of second springs 804, the plurality of telescopic blocks 805 are forced to push the pressing block 202 to abut against and press the upper die 3, preventing the upper die 3 from shifting upward or shaking. Moreover, the second springs 804 and the telescopic blocks 805 have a buffering effect, preventing excessive pressing and thus causing damage to the die.

[0031] In this embodiment, a screw block 8 is arranged on the one-way stud 203. The screw block 8 is threadedly connected to the one-way stud 203. The screw block 8 is movably connected to the inside of the top frame 2. One end of the mounting plate 201 is fixedly connected to the screw block 8.

[0035] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects: To facilitate the processing and positioning of the mold, the staff first place the mold into the notch opened on the base table 1. There are two groups of baffles 301 and the first springs 302 arranged in the base table. Under the elasticity of the two groups of the first springs 302, the two groups of baffles 301 are respectively pushed to closely adhere to both sides of the lower mold 4. After the preliminary positioning of the lower mold 4, the first electric push rod 5 is started. The first electric push rod 5 expands and contracts to push the groove plate 102 to move closer to the mold, and at the same time drives the sliding sleeve 303 to slide on the guiding column 101, ensuring the stability of the movement. Finally, the first motor 6 is started, so that the first motor 6 drives the bidirectional screw rod 106 to rotate through the output shaft. Then, the bidirectional screw rod 106 drives the two groups of threaded sleeves to move relatively through its left-handed and right-handed threads. The first threaded sleeve 104 and the second threaded sleeve 105 respectively drive the two groups of side clamping blocks 103 to move. And there are four groups of side clamping blocks 103 arranged on the base table 1. The four sides of the upper mold 3 and the lower mold 4 are limited by the four groups of side clamping blocks 103, reducing the tediousness of manual operation and improving the accuracy of positioning. To further strengthen the positioning effect, the second electric push rod 7 is started. The second electric push rod 7 expands and contracts to push the movable plate 801 to move closer to the upper mold 3. The second motor 803 is started. The second motor 803 drives the unidirectional screw column 203 to rotate through the output shaft. The unidirectional screw column 203 drives the screw block 8 to move downward. The screw block 8 drives the mounting plate 201 to move downward, so that the movable plate 801 moves above the upper mold 3. Using the elasticity of the second spring 804, the long telescopic column on the telescopic block 805 pushes the pressing block 202 to abut against the top of the upper mold 3. The two pressing blocks 202 limit and press the upper mold 3, avoiding the vertical deviation and shaking of the upper mold 3.
