Detailed description of the invention
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
In figure, cutting knife pedestal 1; Rotary cutter device 2; Cover half drag hook block 3; Cover half cutting knife 4; Dynamic model cutting knife 5; Cutting knife rotating shaft 6; Cutting knife track block 7; Track limited block 8; Circular arc holding tank 9; Fixture block 10; Stopper slot 11; Oblique arc groove 12; Shoulder block 13; Crotch pin 14; Lower protruding block 15; Spatial accommodation 16; Rotatable engagement is along 17; Drag hook is along 18; Product 19; Cast gate 20.
As shown in Figure 2, the maximum innovation of the utility model is the shearing that just automatically can complete cast gate after injection moulding completes in mould, this rotary mould inscribe gate mechanism, to be arranged in mould and to be arranged between dynamic model and cover half, not shown dynamic model and cover half in the present embodiment, this mould inscribe gate mechanism comprises cutting knife pedestal 1, rotary cutter device 2 and cover half drag hook block 3, rotary cutter device 2 is arranged on cutting knife pedestal 1, cover half drag hook block 3 is arranged on a sidepiece of rotary cutter device 2, when mold injection completes, in the process that dynamic model and cover half are opened, utilize the pulling force that dynamic model and cover half separate, cover half drag hook block 3 can drive rotary cutter device 2 to carry out rotation and cut off cast gate 20.
Specifically, rotary cutter device 2 comprises cover half cutting knife 4, dynamic model cutting knife 5, cutting knife rotating shaft 6, cutting knife track block 7 and track limited block 8, here cover half part and dynamic model part is mainly divided into, when mould is installed, in this mould, cutting mechanism order is as follows, dynamic model part: dynamic model cutting knife 5 is arranged in cutting knife pedestal 1, cutting knife pedestal 1 offers the circular arc holding tank 9 included in for dynamic model cutting knife 5, more overall loading dynamic model lock screw, cover half part: cutting knife rotating shaft 6 loads in cover half cutting knife 4, cover half cutting knife 4 can rotate along cutting knife rotating shaft 6, cutting knife rotating shaft 6 both sides load on cutting knife track block 7 vertically, by the cutting knife rotating shaft 6 assembled, cover half cutting knife 4 and track limited block 8 entirety load in cover half, track limited block 8 compresses cover half cutting knife 4 parts, reinstall the sidepiece that cover half drag hook block 3 is hooked in cover half cutting knife 4, the medium position of circular arc holding tank 9 is offered and inserts for cutting knife track block 7 and limit the stopper slot 11 of its position, the positional accuracy that cover half cutting knife 4 rotates is ensured by stopper slot 11, because cutting knife rotating shaft 6 loads in cover half cutting knife 4, being equivalent to cover half cutting knife 4 is like this hinged in cutting knife rotating shaft 6, therefore cover half cutting knife 4 can rotate around cutting knife rotating shaft 6, again because cover half drag hook block 3 is hooked in the sidepiece of cover half cutting knife 4, here the effect of cover half drag hook block 3 is the effects driving cover half cutting knife 4 to rotate.
Between cutting knife track block 7 and dynamic model cutting knife 5, there is card distribution structure, card distribution structure comprises the fixture block 10 being arranged on cutter guide block bottom and the oblique arc groove 12 be opened on dynamic model cutting knife 5, oblique arc groove 12 opening is up-narrow and down-wide shape, oblique arc groove 12 is provided with the shoulder block 13 leant with fixture block 10, so just dynamic model cutting knife 5 and cover half cutting knife 4 can be fixed together, simultaneously due to the existence of oblique arc groove 12, not only play spacing effect, can control cover half cutting knife 4 rotates corresponding angle simultaneously, the sidepiece of dynamic model cutting knife 5 is provided with two crotch pin 14, the sidepiece of cover half cutting knife 4 is provided with lower protruding block 15, the spatial accommodation 16 included in for lower protruding block 15 is formed between two crotch pin 14, on lower protruding block 15, both sides have rotatable engagement along 17, cover half drag hook block 3 is provided with drag hook along 18, drag hook abuts in rotatable engagement along on 17 along 18, here because lower protruding block 15 is positioned at spatial accommodation 16, so just can limit cover half cutting knife 4 axial direction, position sideslip when preventing from pruning cast gate 20, again because drag hook is abut in rotatable engagement along on 17 along 18, when cover half drag hook block 3 moves upward i.e. drag hook move upward along 18, thus driven rotary cooperation makes cover half cutting knife 4 produce rotation along 17, complete cast gate 20 to prune.
The operation principle of this rotary mould inscribe gate mechanism is as follows:
Be illustrated in figure 3 rotary mould inscribe gate mechanism and do not start the view of cutting cast gate, can find out that cover half drag hook block 3 develops with the upper plane of cutting knife pedestal 1, as shown in Figure 4, when mold injection completes, in the process of the state when 10mm opened by cover half and dynamic model, now template-driven cover half drag hook block 3 moves upward 10mm, such cover half drag hook block 3 will be with active and inactive mold cutting knife 4 to move, cover half cutting knife 4 just rotates 10 degree along cutting knife rotating shaft 6, now cast gate 20 cuts off, as shown in Figure 5, now product 19 is separated with cast gate 20, the action-----having completed whole pruning cast gate is also a complete molding cycle, by this rotary mould inscribe gate mechanism, prune cast gate directly to complete in mould, and the molding cycle of mould is constant, other driving force and cylinder is not needed yet, Roof when oil cylinder and pressurize is exerted oneself.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from the scope that spirit of the present utility model defines.
