Please refer to Fig. 3 and Fig. 4, wherein, Fig. 3 is the structural representation of shovel 23 of the present utility model, and Fig. 4 is the explosive view of clamping mechanism 3 of the present utility model.Further, described shovel 23 inside are provided with an inner chamber 231, and the both sides of this inner chamber 231 are respectively equipped with an opening 232.Described clamping mechanism 3 comprises oil cylinder contiguous block 31 and two slide blocks 32; Described oil cylinder contiguous block 31 is arranged in the inner chamber 231 of this shovel 23, and this oil cylinder contiguous block 31 is connected with actuating unit 4 one end of shovel 23 dorsad; The both sides of described oil cylinder contiguous block 31 are respectively equipped with a groove 321; Described two slide blocks 32 are separately positioned in two grooves 321 of this oil cylinder contiguous block 31, and its one end is arranged in inner chamber 231 openings 232 of this shovel 23.Further, the both sides of described fluting 11 are respectively equipped with a concave surface 111 relative with two openings 232 of shovel 23 inner chambers 231.In the present embodiment, the concave surface 111 of described fluting 11 is arc-shaped concave 111.
Concrete, the bottom surface of described groove 321 comprises the first terrace 3211, the second terrace 3213, the first inclined-plane 3212 and the second inclined-plane 3214.Described the first inclined-plane 3212 is identical with the gradient on the second inclined-plane 3214.In described groove 321, towards one end of actuating unit 4, be rear end, the other end is front end; One end of described the first terrace 3211 is connected with groove 321 front ends, and the other end is connected with one end of described the second terrace 3213 by described the first inclined-plane 3212, and the other end of described the second terrace 3213 is connected with these groove 321 rear ends by the second inclined-plane 3214; The distance of described the first terrace 3211 and groove 321 openings 232 is greater than the distance of the second terrace 3213 and groove 321 openings 232.
Concrete, described two slide blocks 32 are separately positioned on two groove 321 inside; One end that described two slide blocks 32 are positioned at groove 321 bottom surfaces is respectively equipped with an inclined-plane identical with these the first inclined-plane 3212 gradients.
When diagonal position mechanism 2 and die main body 1 matched moulds, two slide blocks 32 lay respectively on the second terrace 3213 of two groove 321 inside, and one end of described two slide blocks 32 is stretched in the concave surface 111 of described fluting 11; When diagonal position mechanism 2 and die main body 1 die sinking, two slide blocks 32 lay respectively on the first terrace 3211 of two groove 321 inside, and outside the concave surface 111 of one end of described two slide blocks 32 in described fluting 11.
Described actuating unit 4 comprises an oil cylinder and oil cylinder seat.Described oil cylinder seat is fixedly installed on die main body 1, and described oil cylinder is arranged on this oil cylinder seat, and the piston rod of this oil cylinder is connected with oil cylinder contiguous block 31.
Refer to Fig. 5 a, 5b and 5c, it is respectively, and slide block 32 is initial at matched moulds with oil cylinder contiguous block 31, centre and the position view of the finish time.When diagonal position mechanism 2 carries out matched moulds with die main body 1, first by described oil cylinder pushing oil cylinder contiguous block 31, make shovel 23 toward the direction motion of mould.Now, cover half diagonal position 22, under the promotion of shovel 23, moves down from the ramp way of fixed mold core 21.
Slide block 32 in described clamping mechanism 3 is to be positioned on first terrace 3211 of groove 321 of oil cylinder contiguous block 31 at the initial time of matched moulds.And when oil cylinder contiguous block 31 moves toward the direction of die main body 1, under the extruding of shovel 23, this slide block 32 moves along the first inclined-plane 3212.Along with the movement of slide block 32, slide block 32 is arranged in one end of shovel 23 openings 232 and stretches out gradually outside opening 232, and stretches into gradually in the arc-shaped concave 111 of this fluting 11.When one end of slide block 32 is positioned at the second terrace 3213, the other end of this slide block 32 just stretches in arc-shaped concave 111 and contacts with this concave surface 111.And now, by this slide block 32, diagonal position mechanism 2 is locked with die main body 1.
After diagonal position mechanism 2 and die main body 1 matched moulds, when carrying out injection moulding, if produce recoil strength, will act on cover half diagonal position 22, and recoil strength will be conducted to shovel 23.And because shovel 23 is now connected with the arc-shaped concave 111 of slotting on die main body 1 on 11 by two slide blocks 32.So, by two slide blocks 32, can diagonal position mechanism 2 is locked with die main body 1.
Refer to Fig. 6 a, 6b and 6c, it is respectively, and slide block 32 is initial in die sinking with oil cylinder contiguous block 31, centre and the position view of the finish time.After injection moulding completes, described oil cylinder carries out die sinking by diagonal position mechanism 2 with die main body 1 by oil cylinder contiguous block 31.
Concrete, oil cylinder is first pulled out oil cylinder contiguous block 31 toward the direction of oil cylinder.At the initial time of die sinking, one end that described slide block 32 is in oil cylinder contiguous block 31 is in the second terrace 3213, and its other end is in the concave surface 111 of fluting 11.Along with the movement of oil cylinder contiguous block 31, and under the extruding of shovel 23 openings 232, this slide block 32 moves down along the first inclined-plane 3212.Along with the movement of slide block 32, this slide block 32 one end in arc-shaped concave 111 is exited gradually, and moves toward the direction of shovel 23 openings 232.When one end of slide block 32 is positioned at the first terrace 3211, the other end of this slide block 32 is positioned at and just exits arc-shaped concave 111, and is arranged in the opening 232 of shovel 23.Now, shovel 23 can unimpededly exit from the fluting 11 of this die main body 1, and exits from the inside of die main body 1 with active and inactive mold diagonal position 22, completes die sinking action.
Than prior art, the utility model, by using a clamping mechanism 3, can be realized when diagonal position mechanism 2 and die main body 1 matched moulds, by its locking.Prevent the recoil strength producing due to injection moulding, and cause diagonal position mechanism 2 and die main body 1 seal to reduce, thereby make final product produce the phenomenon of burr.
Further, in the utility model, by using the cooperation of shovel 23, slide block 32, oil cylinder contiguous block 31 and concave surface 111, realized when matched moulds and having locked; And when die sinking, can automatically terminate the state of locking, make the process of matched moulds and die sinking more smooth and easy.
The utility model is not limited to above-mentioned embodiment, if various changes of the present utility model or distortion are not departed to spirit and scope of the present utility model, within if these changes and distortion belong to claim of the present utility model and equivalent technologies scope, the utility model is also intended to comprise these changes and distortion.
