The embodiment of the invention provides a die parting assembly of a die for a product with double crossed buckling positions, which comprises a wedge-shaped connecting block 4, a large sliding block 5 and a small sliding block 6, wherein the large sliding block 5 is used for being inserted and abutted against a first buckling position 2 of the product 1, the small sliding block 6 is used for being inserted and abutted against a second buckling position 3 of the product 1, the small sliding block 6 is obliquely and slidably connected with the bottom end of the wedge-shaped connecting block 4, the large sliding block 5 is longitudinally and slidably connected with the top end of the wedge-shaped connecting block 4, and the small sliding block 6 is transversely and slidably connected with the large sliding block 5.
The product 1 has two crossing knot positions, and first knot position 2 and second knot position 3 are preceding back mould demolding back-off region promptly, and the back-off region is the drawing of patterns angle of two directions, if adopt ordinary two slider demolding alone, the spatial position between two sliders is not enough, causes the interference. Therefore, the matched movement of the large slide block 5 and the small slide block 6 is adopted to complete the mold splitting. As shown in fig. 1 to 5, first, in the mold clamping state, the large slide abuts against the first clamp 2, and the first clamp abutting portion 7 at the end of the small slide 6 abuts against the second clamp 3. When the mold is opened, the wedge-shaped connecting block 4 is moved backwards along the direction of the first buckling position 2, at the moment, the wedge-shaped connecting block 4 moves transversely relative to the large sliding block 5, and the large sliding block 5 is not moved at the moment. Because the wedge-shaped connecting block 4 is connected with the small sliding block 6 in a diagonal sliding mode, and the small sliding block 6 is connected with the large sliding block 5 in a transverse sliding mode, the small sliding block 6 is forced to move longitudinally relative to the large sliding block 5 when the wedge-shaped connecting block 4 moves backwards. When the small slide block 6 moves to a certain position or moves for a preset distance, the small slide block completely exits from the second buckling position 3 to finish the first-stage demoulding. Then, the large sliding block 5 is only required to be integrally moved longitudinally together to exit the first buckling position 2, and the second-stage demoulding is completed. The small slide block 6 is nested in the large slide block 5, so that the interference of the two slide blocks in the moving direction is avoided, the die sinking space is saved, and the product 1 can be smoothly taken out.

Therefore, when the wedge-shaped connecting block 4 moves longitudinally to drive the small sliding block 6 to move transversely to complete the first-stage demoulding, the large sliding block 5 is not moved in the process, and the stop block on the large sliding block 5 slides relative to the closed buckle groove 10. After the first-stage demolding is completed, the stop block slides to the closed edge of the closed buckling groove 10 and is blocked, and at the moment, the wedge-shaped connecting block 4 continues to move longitudinally, and then the stop block is driven to be communicated with the large sliding block 5 to move backwards together, so that the second-stage demolding is completed. Therefore, the two stages of demoulding are seamlessly connected, the demoulding efficiency is improved, the movement process is simplified, the quantity of driving pieces is reduced, and the whole mould opening cost is reduced.

When the first stage demoulding is completed, the boundary of the closed buckle slot 10 just abuts against the buckle plate 11. When the wedge-shaped connecting block 4 moves longitudinally again, the boundary of the closed buckling groove 10 drives the buckling plate 11 to move longitudinally together, so that the large sliding block 5 also moves longitudinally together.
Preferably, the longitudinal moving track of the large sliding block 5 and the longitudinal moving track of the wedge-shaped connecting block 4 are both vertically intersected with the transverse moving track of the small sliding block 6.
