[0030] The following is a specific embodiment of the utility model and is combined with the drawings to further describe the technical scheme of the utility model, but the utility model is not limited to these embodiments.

[0031] As Figures 1-4As shown, a clamp mold with locking function, comprising a base 1, a clamping arm 2, a first drive, a second drive and a locking part.

[0032] In this embodiment, the clamp mold is used for clamping the mold plate, and in actual use, the mold plate is fixed on the workbench, the base 1 and the second drive are arranged on the workbench, the second drive is connected with the base 1 and is used to drive the base 1 to move towards the side close to or away from the mold plate, and in the starting position, the base 1 can be away from the installation position of the mold plate, and after the mold plate is installed, the base 1 is driven by the second drive to move to the mold plate, which can effectively avoid the interference of the base 1 to the installation process of the mold plate and effectively improve the installation efficiency.

[0033] Among them, the clamping arm 2 has a first end 21 and a second end 22, the middle part of the clamping arm 2 is hinged with the base 1, the first end 21 can extend to the outside of the base 1 and can abut with the top of the mold plate to clamp the mold plate, when the base 1 moves towards the side close to the mold plate, the base 1 can drive the first end 21 of the clamping arm 2 to move to the top of the mold plate, only the first end 21 of the clamping arm 2 needs to be pressed down to realize the clamping of the mold plate, and in order to drive the first end 21 of the clamping arm 2 to press down, the first drive is arranged on the base 1, the first drive can be connected with the second end 22, and then the second end 22 can be driven to rise, since the middle part of the clamping arm 2 is hinged with the base 1, the rising of the second end 22 can drive the first end 21 to descend, thereby realizing the clamping action of the mold plate.

[0034] In this embodiment, the locking part is movably arranged on the base 1, and the locking part is provided with a locking portion on the second end 22, the locking part can be inserted between the bottom of the locking portion and the top of the base 1, and the locking part can be cooperated with the locking portion to form a locking structure, of course, after the first drive drives the first end 21 to realize the clamping of the mold plate, the locking part is inserted between the bottom of the locking portion and the top of the base 1, after the insertion, the locking portion cannot continue to move upward due to the limitation of the first end 21, and the locking part cannot move downward due to the support of the base 1, and the two abut with each other, thereby forming a locking structure for the clamping arm 2, since the clamping arm 2 is mechanically locked, the first drive can work after locking, and the clamping of the mold plate can be maintained, the energy consumption can be reduced, and since mechanical locking is adopted, the clamping failure of the mold plate caused by the failure of the drive part can be avoided, and the safety performance is improved.

[0035] In the embodiment, the locking member is a wedge-shaped block 5, and the locking portion is a limiting wheel 221 rotatably arranged at the side of the second end 22. The wedge-shaped block 5 can be inserted between the limiting wheel 221 and the top of the base 1. The wedge-shaped block 5 is a block-shaped object with an inclined surface. During the insertion process, the wedge-shaped block 5 first abuts against the bottom of the limiting wheel 221 at the low part of the inclined surface, and then slowly presses the limiting wheel 221 up and down from the high part to the bottom of the limiting wheel 221, thereby ensuring that the first end 21 keeps clamping the formwork. Since the limiting wheel 221 is rotatable, the difficulty of moving the wedge-shaped block 5 and the limiting wheel 221 can be reduced.

[0036] Of course, in the embodiment, the wedge-shaped block 5 and the limiting wheel 221 are used to abut and limit each other by the inclined surface. Alternatively, a planar abutting and limiting mode can also be used. However, the planar abutting and limiting mode requires higher dimensional accuracy of the abutting member, but should not exceed the scope of the present application.

[0037] Specifically, the limiting wheel 221 is provided with a limiting groove 221a, and the second end 22 is provided with a limiting column 222. When the limiting wheel 221 is assembled to the second end 22 of the clamping arm 2, the limiting column 222 can be inserted into the limiting groove 221a to limit the rotation angle of the limiting wheel 221. The rotation angle can be determined by the opening angle of the limiting groove 221a. The rotation angle can determine the insertion distance of the wedge-shaped block 5. The insertion distance of the wedge-shaped block 5 and the inclination angle of the inclined surface can determine the locking height of the limiting wheel 221. The maximum value of the locking height of the limiting wheel 221 can be determined according to the model of the formwork.

[0038] In the embodiment, in order to improve the stability of the locking, the wedge-shaped block 5 and the limiting wheel 221 are both provided with two. The two limiting wheels 221 are arranged at the two sides of the second end 22 through a first rotating shaft. The two limiting wheels 221 are fixed at the two ends of the first rotating shaft, which can ensure that the two limiting wheels 221 rotate synchronously. The two wedge-shaped blocks 5 and the two limiting wheels 221 abut synchronously, which can ensure that the two sides of the second end 22 are simultaneously acted on and locked, thereby effectively improving the stability of the locking.

[0039] Of course, in order to prevent the limiting wheel 221 from slipping off the wedge-shaped block 5, the width of the wedge-shaped block 5 is greater than that of the limiting wheel 221. When the limiting wheel 221 abuts against the wedge-shaped block 5, the limiting wheel 221 abuts against the middle part of the wedge-shaped block 5, which is not easy to move sideways and can also prevent slipping.

[0040] Since the purpose of reducing the overall occupied volume, in this embodiment, the limit wheel 221 is in contact with the side of the second end 22, in order to prevent the second end 22 from interfering with the wedge block 5, an inclined avoiding portion 223 is arranged on both sides of the bottom of the second end 22, which is used to provide an avoiding effect for the wedge block 5, so that the wedge block 5 can be inserted between the bottom of the limit wheel 221 and the top of the base 1.

[0041] In order to be suitable for the wedge block 5, the avoiding portion 223 should be matched with the wedge block 5, that is, the inclination of the avoiding portion 223 is consistent with the inclination of the wedge block 5, and during the insertion of the wedge block 5, it will not interfere with the wedge block 5, of course, after the wedge block 5 is inserted in place, an abutting portion can be arranged at the bottom of the avoiding portion 223 to abut against the wedge block 5, further ensuring its stability.

[0042] In order to drive the wedge block 5, a gas cylinder 6 is further included, the piston rod of the gas cylinder 6 is in contact with two wedge blocks 5 at the same time, and the gas cylinder 6 can drive the two wedge blocks 5 to move synchronously, that is, the two wedge blocks 5 move towards or away from the side of the second end 22, of course, after the wedge block 5 is used to lock the clamping arm 2, the gas cylinder 6 still needs to remain in working state to avoid that the limit wheel 221 on the clamping arm 2 drives the wedge block 5 to reset.

[0043] Among them, since the limit wheel 221 is in inclined abutment with the wedge block 5, when the limit wheel 221 provides a diagonal force, it can be decomposed into a vertical force and a horizontal force, the vertical force is borne by the base 1, and the horizontal force is borne by the gas cylinder 6, after decomposition, the horizontal force is small, and the gas cylinder 6 is sufficient to support and position the two wedge blocks 5, compared with the motor and the hydraulic cylinder, the gas cylinder 6 consumes less energy, and compared with directly using a hydraulic cylinder at the bottom of the second end 22, energy can be saved.

[0044] In this embodiment, the first driver is a first hydraulic cylinder 3, which is arranged in the base 1 along the vertical direction, and the piston rod of the first hydraulic cylinder 3 can be in contact with the bottom of the second end 22, the first hydraulic cylinder 3 is arranged along the vertical direction, and the extension and retraction movement of the piston rod is also along the vertical direction, when it moves upward, it can abut against the bottom of the second end 22, and can drive the second end 22 to continue to move upward, the first end 21 is driven by the second end 22 to move downward, and the clamping of the template is realized.

[0045] In the embodiment, the workbench is provided with a first sliding groove, a template is fixed at one end of the first sliding groove, the base 1 is movably arranged in the first sliding groove, a second driver is fixed on one side of the base 1 on the workbench and connected with the base 1, the second driver can drive the base 1 to slide in the first sliding groove, so that the base 1 can move towards or away from the template, when the base 1 is driven to move to the template, the clamping arm 2 on the base 1 can clamp the template.

[0046] In the embodiment, the second driver is a second hydraulic cylinder 4, the second hydraulic cylinder 4 is arranged on the workbench along the length direction of the first sliding groove, and the base 1 is provided with a connecting plate, and the piston rod of the second hydraulic cylinder 4 is connected with the connecting plate.

[0047] In the embodiment, the working process of the template clamping device is as follows:

[0048] Preparation stage: the second hydraulic cylinder 4 drives the base 1 to retreat to a safe position;

[0049] Upper die stage: hoist the template to a preset position on the workbench;

[0050] Alignment stage: the second hydraulic cylinder 4 drives the base 1 to move to the upper side of the template;

[0051] Clamping stage: the first hydraulic cylinder 3 starts to work and drives the first end 21 of the clamping arm 2 to press down to clamp the template;

[0052] Locking stage: the cylinder 6 drives the wedge-shaped block 5 to insert into the lower side of the limiting wheel 221, so that mechanical self-locking is realized, and the first hydraulic cylinder 3 releases the pressure;

[0053] Release stage: after the processing is completed, the cylinder 6 controls the wedge-shaped block 5 to retreat.
