The panel 100 may be a single plate or a plurality of plates, and as shown in fig. 1 and 2, may be set according to the use requirement.

Wherein the first and second elastic locking

pieces

520 and 530 each have a degree of freedom to expand and contract in a second direction y perpendicular to the first direction x. The second direction y is perpendicular to the side wall of the corresponding panel, or may be at an angle with respect to the corresponding side wall, as long as the first elastic locking member 520 and the second elastic locking member 530 can protrude from the corresponding side wall in a state of not being subjected to an external force, and is not limited herein.

The first buckle base 540 is provided with an insertion portion 541 for being inserted and matched with the first buckle rod 510, and a first clamping portion 542 and a second clamping portion 543 for being respectively clamped and matched with the first elastic locking member 520 and the second elastic locking member 530. Specifically, the inserting portion 541 may be a slot, a slider, or the like, as long as the inserting and fitting with the first fastening rod 510 can be achieved, which is not limited herein.

The first buckle lever 510 is provided with a first abutting portion 511 and a second abutting portion 512, a distance between the first abutting portion 511 and the second abutting portion 512 is larger than a distance between the first clamping portion 542 and the second clamping portion 543, and the first abutting portion 511 and the second abutting portion 512 are used for respectively abutting against the first elastic locking member 520 and the second elastic locking member 530 when the first buckle lever 510 is separated from the first buckle base 540, so that the first elastic locking member 520 and the second elastic locking member 530 are separated from the first buckle base 540 according to a preset sequence.

The concrete theory of operation of the mold opening mechanism that this application embodiment provided is as follows:

When the mold is opened, a pulling force away from the shovel base plate 200 is applied to the panel 100, and the first fastening rod 510 moves along with the pulling force, and gradually separates from the inserting portion 541 in the first fastening base 540. During this period, the first top contact portion 511 applies a pushing force to the first elastic locking member 520 to separate the first elastic locking member 520 from the first fastening seat 540, thereby separating the shovel base plate 200 from the movable mold plate 400, and then the second top contact portion 512 applies a pushing force to the second elastic locking member 530 to separate the second elastic locking member 530 from the first fastening seat 540, thereby separating the fixed mold plate 300 from the movable mold plate 400. This realizes the sequential opening of the panel 100, the shovel substrate 200, and the fixed die plate 300.

When the mold opening device is used, different mold inserts are sequentially connected to the panel 100, the shovel base plate 200 and the fixed mold plate 300 according to the mold opening sequence, so that the core-pulling sequence of the mold inserts can be controlled, and the mold opening sequence is guaranteed. If the insert a is connected with the panel 100, the insert C is connected with the shovel base plate 200, and the insert B is connected with the fixed die plate 300, the insert a and the insert C can be controlled to be drawn out first, and then the insert B can be drawn out.

The mold opening mechanism provided by the embodiment of the application controls the separation sequence of the panel 100, the shovel substrate 200, the fixed mold plate 300 and the movable mold plate 400 during mold opening through the first fastening assembly 500, and is simple and convenient to operate and stable in structure. By adopting the mold opening mechanism provided by the embodiment of the application, sequential core pulling of each insert respectively connected with the panel 100, the shovel substrate 200 and the fixed mold plate 300 can be realized. And the first machine component 500 of detaining in this application embodiment is difficult for fatigue failure than spring or nylon plug for the die sinking process is more stable, reliable.

Further, in order to ensure that the panel 100, the shovel substrate 200, the fixed mold plate 300, and the movable mold plate 400 can move in a preset direction (i.e., the first direction x) in the mold opening state, a guide rail extending to the side of the movable mold plate 400 along the first direction x is installed on the panel 100, and holes for the guide rail to pass through or be inserted into are respectively formed on the shovel substrate 200, the fixed mold plate 300, and the movable mold plate 400. Specifically, in an embodiment of the present application, the guide rail includes a plurality of guide rods arranged in parallel, and the plurality of guide rods can ensure that the shovel substrate 200, the fixed template 300 and the movable template 400 linearly move during the mold closing and opening process, thereby ensuring the stability and reliability of the mold opening and closing sequence of the mold opening mechanism.
