Detailed description of the invention
Referring to figs. 1 through Fig. 8, Die Embodiment of the present invention is described further.
A kind of mould, comprise mould bases and core 2, described mould bases comprises upper bolster 1, cushion block 9, die shoe 5, guide pillar, liftout attachment 4 and die shoe 5, described upper bolster 1, core 2, cushion block 9, die shoe 5, liftout attachment 4, die shoe 5 is all connected successively by guide pillar, described core 2 is fixed with side-drawing mechanism 7, described side-drawing mechanism 7 comprises fixed block 71 and takes out block 72 for the side of forming hole on product or groove, described fixed block 71 is arranged on core 2, described side is taken out block 72 and is connected with fixed block 71 slippage, upper bolster 1 is provided with glue mouth 6, core 2 comprises punch 22 and die 21, die 21 of the present invention can be fixedly connected with upper bolster 1, die 21 is fixedly connected with die shoe 5, certainly, vice versa, when injection moulding, upper bolster 1 moves towards die shoe 5, thus punch 22 is closed with die 21, a cavity is there will be between die 21 and punch 22, Angle Pin 11 is preferably arranged on die 21 by the present invention simultaneously, fixed block 71 is connected with punch 22 slippage, in the motion process of Angle Pin 11 along with upper bolster 1, because fixed block 71 is provided with gathering sill, therefore Angle Pin 11 can move towards the direction of punch 22, until one end that block 72 is taken out in side is positioned at cavity, the plastics of at this moment melting enter in cavity from glue mouth 6, and owing to taking out the existence of block 72 in side, injection moulding product out there will be a groove or a hole, after injection mo(u)lding, upper bolster 1 moves towards the direction away from die shoe 5 with die 21 and Angle Pin 11, due to the existence of gathering sill, fixed block 71 also can move towards the direction away from punch 22, thus make side take out block 72 to depart from the groove on injection moulding product out or hole, liftout attachment 4 comprises knock-pin 41 and push pedal 42, now push pedal 42 drives knock-pin 41 to move towards the direction of upper bolster 1, thus the product processed is ejected.
The control device 8 taking out block 72 slip for controlling side is provided with in fixed block 71, described control device 8 comprises conflict block 83, sealing block 82 and injection apparatus 81, injection apparatus 81 comprises the first injection apparatus 811 and the second injection apparatus 812, described fixed block 71 is provided with chute 711, described side is taken out block 72 and is connected with fixed block 71 slippage by chute 711, the accommodating cavity 712 communicated with chute 711 is provided with in described fixed block 71, described conflict block 83 is slidably arranged in accommodating cavity 712, described sealing block 82 is fixedly connected with conflict block 83 and sealing block 82 and accommodating cavity 712 are formed and be sealed and matched, the sidewall of described accommodating cavity 712 is provided with scavenge port, described scavenge port comprises the first scavenge port 713 and the second scavenge port 714, the first described scavenge port 713 and the second scavenge port 714 lay respectively at the both sides of sealing block 82, the first described injection apparatus 811 is connected with the second scavenge port 714 with the first scavenge port 713 respectively with the second injection apparatus 812, the present invention preferably by the first scavenge port 713 near chute 711, accommodating cavity 712 is divided into the first accommodating cavity 7121 communicated with the first scavenge port 713 and the second accommodating cavity 7122 communicated with the second scavenge port 714 by sealing block 82, in time not needing to carry out grooving or borehole to product, first injection apparatus 811 is toward gas jet or liquid in accommodating cavity 712, and sealing block 82 and accommodating cavity 712 sidewall are tightly connected, along with the continuous rising of the gas in the first accommodating cavity 7121 or total amount of liquid, therefore the gas in accommodating cavity 712 or liquid meeting crush seal block 82, thus sealing block 82 is moved towards the direction away from chute 711, accordingly, conflict block 83 also can move towards the direction away from chute 711, and conflict block 83 and side are taken out between block 72 and are provided with link gear, linkage structure comprises oblique dovetails 10, described oblique dovetails 10 is fixedly connected with conflict block 83, described side is taken out block 72 and is provided with the dovetail slideway 721 coordinated with oblique dovetails 10, described dovetail slideway 721 is for being tilted to lower setting, therefore, side can be driven to take out block 72 move together when conflict block 83 is away from chute 711, thus the sidewall of the one end protruding from fixed block 71 and fixed block 71 of making side take out block 72 is at same plane, like this when injection mo(u)lding, groove or through hole would not be there is in injection moulding product out, and in needing to add groove or through hole on injection moulding product out, the second injection apparatus 812 is only needed to work, liquid or gas is made to enter in the second accommodating cavity 7122 by the second scavenge port 714, along with the air pressure of the second accommodating cavity 7122 or hydraulic pressure constantly raise, thus is moved in the direction of sealing block 82 towards chute 711, and gas in the first accommodating cavity 7121 or liquid can be flowed out by the first scavenge port 713, when conflict block 83 moves to upper extreme position time, conflict block 83 protrudes and fixed block 71, groove or hole will be formed like this when injection moulding, the effect of controlled working shape of product can be reached by the first injection apparatus 811 or the work of the second injection apparatus 812, easy to operate, do not need manually to go dismounting, improve working (machining) efficiency.
The first injection apparatus 811 in the present invention and the second injection apparatus 812 can be air pump, also can be oil pump.
Accommodating cavity 712 is columniform accommodating cavity 712, the outer ring surface of described sealing block 82 is provided with the annular groove 821 of concentric setting, O-ring seal 3 is provided with in described annular groove 821, described O-ring seal 3 is formed with accommodating cavity 712 and is sealed and matched, columniform accommodating cavity 712 can improve the sealing between sealing block 82 and accommodating cavity 712, the existence of simultaneously O-ring seal 3, can sealing further between enhanced leaktightness block 82 and accommodating cavity 712.
Mould of the present invention may be used for the mould making spoon and fork, when needs make spoon time, control device 8 works, thus make side take out block 72 to move towards the direction away from die 21, and then the plane reaching one end and die 21 that block 72 is taken out in side is in same plane, like this, injection molding product is out just spoon, when needs processing fork time, control device 8 works, thus the one end making side take out block 72 protrudes from groove, when matched moulds time, one end of block 72 is taken out in side and punch 22 offsets, such injection molding product is out then a fork, driving control device 8 is only needed when each switching, do not need manually to remove more mold exchange, improve working (machining) efficiency.
The above is only the preferred embodiment of the present invention, protection scope of the present invention be not only confined to above-described embodiment, and all technical schemes belonged under thinking of the present invention all belong to protection scope of the present invention.It should be pointed out that for those skilled in the art, some improvements and modifications without departing from the principles of the present invention, these improvements and modifications also should be considered as protection scope of the present invention.
