Description
Technical field
This utility model relates to the corollary equipment of injection machine, and more specifically, this utility model relates in a kind of mould
Automatic shearing stub bar device.
Background technology
Generally working of plastics is after moulding, and stub bar is connected by cast gate with product, needs workman to enter the stub bar at cast gate
Row is pruned, and wastes time and energy, and the out-of-flatness again that cast gate is pruned is attractive in appearance.Usage amount for working of plastics is big, to quality drastically at present
Rise；But owing to the prices of raw materials, cost of labor go up in recent years, adding that the market competition is growing more intense, the profit of enterprise is constantly
Decline, how to reduce cost, injection molding product surface quality can be improved again, by technological improvement, realize automated production and be
The major issue that plastics-production enterprise is extremely urgent.When existing solution is die sinking from top board eject cutting knife by gate cutting,
Both approaches is all to shear after die sinking, and owing to now plastics are the most cooled hardening, cutting knife is easy to wear to fracture, and cuts
Gate land out-of-flatness after cutting is attractive in appearance, and product quality does not increases, and still needs artificial pruning, adds cost of labor, extends and hand over
The goods duration.
It addition, cannot carry out automatic shearing in prior art mold, its reason is, the oil cylinder volume that is conventional is excessive,
The little oil cylinder that cannot meet large volume in space inside mould is installed and the arrangement of oil circuit；Two is that the pressure of oil pressure unit cannot
Reach the dynamics of automatic shearing.
Utility model content
The utility model discloses automatic shearing stub bar device in a kind of mould, it is possible to after die cavity breaks full plastics, product
The connecting portion of product and stub bar it is automatically separated, it is ensured that cast gate tangent plane smooth attractive in appearance, it is not necessary to manually prune before cooling.
This utility model be the technical scheme is that
Automatic shearing stub bar device in a kind of mould, its mould includes fixed mold core and mavable module core, described fixed mold core and described
Forming formed product chamber between mavable module core, its automatic shearing stub bar device is arranged in mould, described automatic shearing stub bar device
Including miniature oil cylinder, oil cylinder piston and cutting knife, described miniature oil cylinder bottom offers oil-in, and described oil cylinder piston is arranged on
In described miniature oil cylinder, being connected with described cutting knife of described oil cylinder piston, described cutting knife is socketed with spring；At described miniature oil
The bottom of cylinder is provided with connecting portion, and described connecting portion connects snap joint.
Further, described oil cylinder piston is socketed O and Glais ring.
Further, tool bore is offered in the side of described mavable module core, is arranged in tool bore by described cutting knife, and described cutting knife is for falling
T-shaped, the lower bottom base of described cutting knife is connected with described oil cylinder piston.
Further, described connecting portion is provided with thread.
Further, described snap joint is connected with oil pipe, and described oil pipe connects dynamic source, and described power source is by controlling
Molding block controls.
After using technique scheme, this utility model can complete the automatic shearing operation of plastic stub bar, due to
This utility model works asynchronously with mould in use, and plastic is cut in the case of cooling the most completely
Cut, it is possible to effectively prevent cutting knife to be worn, fracture, improve the surface quality of injection molding product, make surface the most smooth attractive in appearance,
When mould is opened, product and cast gate have been separated from, it is not necessary to artificial shearing can directly pack shipment, improve production efficiency and
Save cost of labor.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of automatic shearing stub bar device in this utility model mould；
