Abstract
The utility model discloses a kind of injection mold needle-valve adhesive sealing mechanism, comprise cover half part, dynamic model part and the flow channel component be located in cover half part, injection moulding die cavity is formed between described cover half part and dynamic model part, described flow channel component has the cast gate communicated with injection moulding die cavity, be provided with reciprocally mobile with the needle-valve sealing cast gate in described flow channel component, at described cover half part one side, cylinder is set, described cylinder is moved back and forth to drive needle-valve by a lever assembly, by arranging the needle-valve of reciprocally movement at cast gate place, after the complete cooling forming of hot melting plastic in injection moulding die cavity, because cast gate is blocked by needle-valve, hot melting plastic in hot melting plastic in cast gate and injection moulding die cavity is separated, during hot melting plastic cooling forming, hot melting plastic in cast gate can not be cooled, thus can not waste material be produced, reduce the waste of waste material, reduce production cost, without the need to artificial removal's waste material, reduce labor strength, improve production efficiency.
Description
Technical field
the utility model relates to technology of die manufacturing field, particularly a kind of injection mold needle-valve adhesive sealing mechanism.
Background technology
At present, existing injection mold normally arranges cast gate, hot melting plastic is delivered to injection mo(u)lding in the die cavity of injection mold through hot flow path and goes out the plastic of predetermined shape, but there is following defect in this kind of version: when after the plastic cooling after injection mo(u)lding, the hot melting plastic at cast gate place also cools, and forms waste material thereupon, plastic also needs artificial removal's waste material after taking out, add the labour intensity of workman, reduce production efficiency, and cause the waste of a large amount of waste material.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of injection mold needle-valve adhesive sealing mechanism reducing waste material, effectively enhance productivity.
For solving the problems of the technologies described above adopted technical scheme: a kind of injection mold needle-valve adhesive sealing mechanism, the flow channel component comprising cover half part, dynamic model part and be located in cover half part, injection moulding die cavity is formed between described cover half part and dynamic model part, described flow channel component has the cast gate communicated with injection moulding die cavity, be provided with reciprocally mobile with the needle-valve sealing cast gate in described flow channel component, arrange cylinder at described cover half part one side, described cylinder is moved back and forth to drive needle-valve by a lever assembly.
Be further used as improvement of the present utility model, described lever assembly comprises a power transmission rod member, and described power transmission rod member is by a pin-hinges in cover half part, and the two ends of described power transmission rod member are connected with the tailpiece of the piston rod of cylinder with the end of needle-valve respectively.
Beneficial effect: this injection mold passes through with needle-valve adhesive sealing mechanism the needle-valve arranging reciprocally movement at cast gate place, after the complete cooling forming of hot melting plastic in injection moulding die cavity, because cast gate is blocked by needle-valve, hot melting plastic in hot melting plastic in cast gate and injection moulding die cavity is separated, during hot melting plastic cooling forming, hot melting plastic in cast gate can not be cooled, thus can not waste material be produced, reduce the waste of waste material, reduce production cost, without the need to artificial removal's waste material, reduce labor strength, improve production efficiency; Meanwhile, owing to being arranged on the side of cover half part as the cylinder of driver part, the structure of whole injection mold can be simplified, greatly reduce the thickness of injection mold.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described further;
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
With reference to Fig. 1, a kind of injection mold needle-valve adhesive sealing mechanism of the utility model, the flow channel component 30 comprising cover half part 10, dynamic model part 20 and be located in cover half part 10, injection moulding die cavity is formed between cover half part 10 and dynamic model part 20, flow channel component 30 has the cast gate 31 communicated with injection moulding die cavity, be provided with reciprocally mobile with the needle-valve 32 sealing cast gate in flow channel component 30, arrange cylinder 40 at described cover half part 10 1 side, cylinder 40 is moved back and forth to drive needle-valve 32 by a lever assembly 50.
In the present embodiment, the front end geometry of needle-valve 32 and the shape of cast gate 31 match, when in injection moulding die cavity fill hot melting plastic after, cylinder 40 works and drives needle-valve 32 to move down by lever assembly 50, the front end of needle-valve 32 is made to block cast gate 31, after the complete cooling forming of hot melting plastic in injection moulding die cavity, shaping plastic also ejects by mould die sinking, because cast gate 31 is blocked by needle-valve 32, hot melting plastic in hot melting plastic in cast gate 31 and injection moulding die cavity is separated, during hot melting plastic cooling forming, hot melting plastic in cast gate 31 can not be cooled, thus can not waste material be produced, reduce the waste of waste material, reduce production cost, without the need to artificial removal's waste material, reduce labor strength, improve production efficiency.
As preferably, lever assembly 50 comprises a power transmission rod member 51, and power transmission rod member 51 is hinged in cover half part 10 by a pin 52, and the two ends of power transmission rod member 51 are connected with the tailpiece of the piston rod of cylinder 40 with the end of needle-valve 32 respectively.
By cylinder 40 is fixedly mounted on cover half part 10 side and together with by power transmission rod member 51 needle-valve 32 being in transmission connection with cylinder 40, the cylinder assembly of abandoning tradition and the positional structure of needle valve assembly, make whole injection mold structure compacter, greatly reduce the thickness of injection mold.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-mentioned embodiment, in the ken that described technical field those of ordinary skill possesses, various change can also be made under the prerequisite not departing from the utility model aim.
