Description
Technical field
The present invention relates to plastic mould, relate in particular in toothbrush class mould, plant pore moulding take out brush needle construction.
Background technology
The most of toothbrush of current industry processing enterprise, when processing toothbrush, in its mould, corresponding brush place needs one-shot forming to go out to plant pore, plants pore and need carry out moulding by brushing pin.In mould structure, need correspondingly to arrange and take out brush needle construction; The structure of this kind of mould comprises: upper (front) mould, under (afterwards) mould, brush pin etc.Motion flow is: counterdie is together with brush pin feeding in the lump, matched moulds, injecting glue, parting (counterdie drives brush pin to reset).Or first move back brush pin, open again the version (increasing brush pin with respect to the actuating mechanism of counterdie) of die joint.
The drawback of these two kinds of versions is: toothbrush body is easily sticky in the die cavity of (front) mould.After somatotype, need manually in patrix die cavity, to take out toothbrush body; Or increase special upper (front) mould ejecting structure, increased together manually-operated operation, make that artificial intensity is large, production efficiency is low, improve the cost of product.
Summary of the invention
The present invention is directed to above problem, provide a kind of and guaranteed to brush in the smooth situation of extracting out of pin, all products energy " automatically " are separated with patrix, and then enhance productivity, and toothbrush die simple in structure, cost is low is taken out brush needle device.
Technical scheme of the present invention is: described mould comprises upper die and lower die, gripper shoe, cushion block, some brush pins and lower die discharging mechanism, offers respectively upper and lower die cavity on the opposite face of described upper and lower mould; Described brush pin runs through described counterdie, stretches in described upper and lower die cavity; Described gripper shoe is positioned at the bottom of described counterdie, and described cushion block is located at described gripper shoe bottom;
Also comprise brush pin movement device, described brush pin movement device comprises brush pin push rod, brush pin fixed head, spring and stop screw; The lower end of described brush pin push rod is provided with the step circle that is greater than shaft;
In described gripper shoe, offer spring placement hole, on described counterdie, offer up-small and down-big shoulder hole one, described spring placement hole and described shoulder hole one concentric; Described brush pin push rod and spring are located in described shoulder hole one and spring placement hole, and the bottom surface of described brush pin push rod step circle contacts the end face of described spring, and the bottom surface of described spring contacts the end face of described cushion block;
On described counterdie, also offer up big and down small shoulder hole two, in described gripper shoe, offer screwed hole two; Described shoulder hole two and screwed hole two concentrics; Described stop screw runs through from top to bottom described shoulder hole two, connects described screwed hole two again;
On described counterdie, offer aperture brush pin placement hole down, described brush pin fixed head is located in described brush pin placement hole, and described some brush pins are fixedly connected on the end face of described brush pin fixed head.
The height in described shoulder hole two upper step holes is greater than the height of the head of screw of described stop screw.
The height of described shoulder hole one bottom stepped hole is greater than the height of described brush pin push rod step circle.
Also comprise brush pin fixed head attachment screw, in described gripper shoe, offer screw hole, described brush pin fixed head bottom surface offers screwed hole one, and described brush pin fixed head attachment screw passes described screw hole, connects the screwed hole one of described brush pin fixed head bottom surface from bottom.
Structure of the present invention can realize the sequential parting of mould and control when molding procedure is complete, that is: the first somatotype (somatotype) of upper and lower mould; Somatotype after counterdie and gripper shoe is taken out brush pin (twice parting) simultaneously.
Between counterdie of the present invention and gripper shoe, there is no " fixing, location " connector, why can realize counterdie and gripper shoe " disjunctor " with patrix somatotype, be due to the structures shape of the brush pin movement device of this case.The brush pin movement device of this case is when base plate is separated, base plate drives cushion block, cushion block to drive gripper shoe, gripper shoe to drive brush pin fixed head, brush pin fixed head to drive brush pin, brush pin to drive product, realized the separated smoothly of all over products and patrix, and counterdie, gripper shoe, brush pin, brush pin fixed head, cushion block etc., under the effect of " package power " between brush pin and product, still " are connected as a single entity ".Until the stroke of brush pin push rod in shoulder hole one " used up ".
After the trip " is used up ", gripper shoe still moves downward under the drive of base plate, but now spring by brush pin push rod, to start " promotion " counterdie separated with gripper shoe, i.e. twice parting.Gripper shoe drives stop screw (sky is located in the shoulder hole two of counterdie) motion in the lump, and after the stroke in stop screw and shoulder hole two " is used up ", twice parting finishes.Gripper shoe still drives counterdie to move in the lump.
The two-time parting that the present invention realizes by brush pin movement device, can make product all successfully separated with patrix.And after delaying certain hour (i.e. the time of a somatotype), will brush pin and depart from product in twice parting process, now product is due to the effect of aforementioned time, and curing performance is better, and the pin hole quality of formation is higher.Compact conformation of the present invention, has alleviated personnel labor intensity, has improved production efficiency.
