The invention provides a butt-inserted sliding side concave die mechanism.
Referring to fig. 1 to 3, the opposite-insert sliding side concave die mechanism of the embodiment of the invention comprises a plurality of sliding side concave blocks 3 and shrinkage side concave blocks 5 which are arranged at intervals and are relatively inserted and connected, and an inner die body of a circumferential connecting structure is formed by radial relative movement between the sliding side concave blocks 3 and the shrinkage side concave blocks 5, and the sliding side concave blocks 3 and the upper die rod 2 of the embodiment are matched to slide axially, the shrinkage side concave blocks 5 are matched to slide radially with a side concave bearing seat 6, and a closed inner concave die cavity is formed by the inner die body formed by the matching of the sliding side concave blocks 3 and the shrinkage side concave blocks 5, the upper die 1 and the lower die 10.
Specifically, the outer peripheral surface of the upper mold rod 2 in this embodiment is of a conical structure with a wide upper part and a narrow lower part, and a plurality of axially arranged axial sliding grooves 21 are uniformly formed in the outer peripheral surface of the upper mold rod 2 and are matched and slidingly connected with the sliding side concave block 3, and meanwhile, a plurality of radial sliding grooves 61 uniformly formed in the bottom end of the shrinkage side concave block 5 and the edge of the side concave bearing seat 6 are matched and slidingly connected. After the sliding side concave block 3 and the shrinkage side concave block 5 are inserted in place relatively, the convex blocks 4 respectively arranged on the outer peripheral surfaces of the sliding side concave block 3 and the shrinkage side concave block 5 are assembled together to form a convex positioning part of the concave part of the manufacturing part 7. Preferably, the axial sliding groove 21 of the present embodiment is a dovetail groove, and the inner surface of the sliding side concave block 3 is provided with a side dovetail projection 31 that slides in cooperation with the axial sliding groove 21, so that the sliding side concave block 3 can slide axially relative to the upper die rod 2. Meanwhile, the radial sliding groove 61 in this embodiment is a dovetail groove with a narrow outer portion and a wide inner portion, and the bottom of the shrinkage side concave block 5 is provided with a bottom dovetail bump 51 to be matched with the radial sliding groove 61, so as to realize radial sliding of the shrinkage side concave block 5 relative to the radial sliding groove 61. In addition, in order to limit the axial movement of the shrinkage side concave block 5 relative to the upper mold rod, in this embodiment, a bottom dovetail bump 52 is provided at the bottom end of the shrinkage side concave block 5 and is matched with a bottom dovetail groove 62 provided at the bottom surface of the side concave bearing seat 6.

Because the sliding side concave block 3 moves in the radial outward direction, the shrinkage side concave block 5 moves in the radial inward direction, so that the sliding side concave block 3 and the shrinkage side concave block 5 move relatively in opposite directions, and are connected through the final clamping of the side inclined planes, the convex blocks 4 respectively arranged on the outer peripheral surfaces of the sliding side concave block 3 and the shrinkage side concave block 5 form a convex positioning part of the concave part of the manufactured part 7 together, and the casting forming of the part 7 can be realized through the cooperation with the upper die 1 and the lower die 10.
After the part 7 is manufactured, the sliding side concave block 3 is moved outwards by pulling the upper die rod 2 outwards, the sliding side concave block is closed at the central position of the upper die rod 2 and finally separated from the upper die 1, the shrinkage side concave block 5 is slid towards the center by pushing the locking ring 8 to move upwards by the pushing rod 9, the shrinkage side concave block 5 moves inwards in the radial direction to separate from the part 7, and when the sliding side concave block 3 and the shrinkage side concave block 5 are completely separated from the part 7, the part 7 is separated from each other by the upper die 1 and the upper die 10, so that the part 7 is finally separated from each other.
The invention also provides a control method using the opposite-plug type sliding side concave die mechanism, which comprises the following steps:
Step S1: the sliding side concave block 3 is positioned at the bottom end of the upper die rod 2 and inserted into the upper die 1 through the upper die top hole 11, and the shrinkage side concave block 5 is in a gathering state and penetrates into the lower die 10 through the lower die bottom hole 101;
Step S2: after the upper die 1 and the lower die 10 are clamped, the upper die rod 2 moves downwards to enable the sliding side concave block 3 to move upwards relative to the upper die rod 2 to generate radial outward movement, and the locking ring 8 is pushed upwards by the pushing rod 9 to enable the shrinkage side concave block 5 to slide inwards relative to the side concave bearing seat 6;
step S3: the sliding side concave block 3 and the shrinkage side concave block 5 move radially in opposite directions and are mutually clamped and connected through side inclined planes, and the convex blocks 4 respectively arranged on the outer peripheral surfaces of the sliding side concave block 3 and the shrinkage side concave block 5 are assembled together to form a convex positioning part of the concave part of the manufacturing part 7;
Step S4: after the part 7 is manufactured and produced, the upper die rod 2 is pulled outwards to enable the sliding side concave block 3 to move downwards to approach the center of the upper die rod 2 so as to finally separate from the upper die 1, the push rod 9 pushes the locking ring 8 to move upwards to enable the shrinkage side concave block 5 to swing towards the center so as to approach the shrinkage side concave block 5, the shrinkage side concave block 5 moves inwards in the radial direction so as to separate from the part 7, the sliding side concave block 3 and the shrinkage side concave block 5 are finally completely separated from the part 7, and the part 7 realizes final demolding.
