particularly, described axle core and described fortune water block are all positioned at described counterdie, and described axle core rotates with described counterdie and is connected, and described fortune water block is slidably connected mutually with described counterdie.
more specifically, described mould emptier also comprises and to be fixedly connected with described fortune water block and the water supply connector be connected with described intake chamber, to be fixedly connected and the water out adapter be connected with described effluent trough with described fortune water block.
more specifically, described water supply connector and described water out adapter stretch out described counterdie and can slide in described counterdie.
particularly, the junction of described fortune water block and described axle core is provided with oil sealing.
particularly, described intake chamber and described effluent trough are cannelure.
particularly, described water inlet road and described water outlet path extend all along the vertical direction and be arranged in parallel.
particularly, described axle core offers connectivity slot, the upper end on described water inlet road is connected with described connectivity slot respectively with the upper end of described water outlet path.
more specifically, described connectivity slot is cannelure.
more specifically, the junction of described water inlet road, described water outlet path and described connectivity slot is provided with sealing ring.
due to the enforcement of above technical scheme, the present invention compared with prior art tool has the following advantages:
the present invention, by the improvement to mould emptier, makes mould emptier is provided with cooling water channel, can cool, decrease the fraction defective of product, also improve the mold use life-span to product and mould.
Accompanying drawing explanation
accompanying drawing 1 is structural representation of the present invention;
accompanying drawing 2 is the structural representation of mould emptier;
wherein: 1, counterdie; 2, mould emptier; 3, axle core; 4, intake road; 5, water outlet path; 6, water block is transported; 7, intake chamber; 8, effluent trough; 9, connectivity slot; 10, water supply connector; 11, water out adapter; 12, oil sealing; 13, sealing ring.
Detailed description of the invention
below in conjunction with specific embodiment, the present invention will be further described in detail, but be not limited to these embodiments.
as shown in the drawings, a kind of mould for the production of product with tooth, comprises patrix, the counterdie 1 coordinated with patrix, the mould emptier 2 for the demoulding that can move along the vertical direction.
mould emptier 2 comprises the axle core 3 be connected that to rotate with counterdie 1, be opened in the water inlet road 4 for intaking in axle core 3, be opened in the water outlet path 5 for water outlet on axle core 3, to be set on axle core 3 and the fortune water block 6 that can move along the vertical direction together along with axle core 3, be opened in the intake chamber 7 be connected on fortune water block 6 and with the bottom on water inlet road 4, be opened in and transport on water block 6 and the effluent trough 8 be connected with the bottom of water outlet path 5, be opened in the connectivity slot 9 on axle core 3, be fixedly connected and the water supply connector 10 be connected with intake chamber 7 with fortune water block 6, be fixedly connected and the water out adapter 11 be connected with effluent trough 8 with fortune water block 6, the water inlet upper end on road 4 is connected by connectivity slot 9 with the upper end of water outlet path 5.
the periphery of axle core 3 is formed with the screw thread matched with the tooth of product.
axle core 3 and fortune water block 6 are all positioned at counterdie 1, and axle core 3 and counterdie 1 are rotated by screw thread and be connected, and fortune water block 6 is slidably connected mutually with counterdie 1, and water supply connector 10 and water out adapter 11 stretch out counterdie 1 and can slide in counterdie 1.
fortune water block 6 is provided with oil sealing 12 with the junction of axle core 3.Water inlet road 4, water outlet path 5 are provided with sealing ring 13 with the junction of connectivity slot 9.
intake chamber 7 and effluent trough 8 are cannelure.Connectivity slot 9 is cannelure.Water inlet road 4 and water outlet path 5 extend all along the vertical direction and be arranged in parallel.In the process of rotating with water outlet path 5 on water inlet road 4, water inlet road 4 is positioned at intake chamber 7 and connectivity slot 9 all the time with the opening that intake chamber 7 is communicated with connectivity slot 9, and the opening that water outlet path 5 and effluent trough 8 are communicated with connectivity slot 9 is positioned at effluent trough 8 and connectivity slot 9 all the time.
die sinking operating principle: the first die sinking of upper and lower mould 1; Axle core 3 rotates and moves downward, and deviates from product threaded portion; Continue die sinking, take out product.
mould assembling action principle: axle core 3 rotates and moves upward, upper and lower mould 1 matched moulds.
fortune water principle: water enters intake chamber 7 from water supply connector 10, then enter in connectivity slot 9 through water inlet road 4, effluent trough 8 is entered again through water outlet path 5, finally flow out from water out adapter 11, because fortune water block 6 can move up and down together along with axle core 3, intake chamber 7 and effluent trough 8 are cannelure, so, when axle core 3 rotates, the opening of water inlet road 4 and water outlet path 5 is positioned at intake chamber 7 and effluent trough 8 all the time, in like manner, another opening of water inlet road 4 and water outlet path 5 is positioned at connectivity slot 9 all the time, and fortune water is achieved.
opening after mould assembling action and product injection moulding complete, all passing into cooling water in water inlet road 4 and water outlet path 5 and product and mould are cooled, to complete production.
