It is equipped with cooling-water duct 205 in bottom upper mold core 51, bottom of the pot side form core 52, bottom of the pot oil return side form core 53 and bottom of the pot lower mold core 55.
Bottom of the pot core 551 is divided into fixed core, core A555, core B556, core C557 and core D558, fixed core
Be overall structure with bottom of the pot lower mold core 55, bottom of the pot lower mold core 55 is equipped with core slot 559, in core slot 559 equipped with core A555,
The bottom of core B556 and core C557, core A555, core B556 and core C557 are equipped with core boss, core A555's
Core boss is mounted in the boss slot of lower mold core 55, and the core boss of core B556 and core C557 are mounted on core A555's
In boss slot；Core D558 is mounted in the cored hole 5511 of fixed core.
Bottom of the pot upper mold core 51, connecting seat Loose core block 54, flowline core_pulling pole 542, bottom of the pot side form core 52, bottom of the pot oil return side form
Core 53, bottom of the pot lower mold core 55, oil return pipe core_pulling pole 534, oil return pipe upper mold section 512 and oil return pipe female die 554 are combined shape
At bottom of the pot cavity, one-pass molding is realized.
Connecting seat Loose core block 54 is obliquely installed, and be slidably installed fall in love with it is conveniently stripped on die holder 1.In connecting seat Loose core block 54
The one-pass molding of connecting seat and flowline is realized equipped with flowline core_pulling pole 542.Flowline core_pulling pole 542 is mounted on connecting seat
Make simple in structure, the difficulty of processing for reducing connecting seat is separately provided in flowline core_pulling pole 542, reduces processing cost, and make
Mold is safeguarded and repairs a die conveniently, and reduction use cost is realized.
Mounting hole core pulling column 522 is integrally formed with bottom of the pot side form core 52 avoids the surface of mounting hole from generating burr influence oil can
Installation.
Location hole core_pulling pole 532, oil return pipe core_pulling pole 534 and oil return pipe shaped insert 535 reduce bottom of the pot oil return side form
The difficulty of processing of core 53 reduces processing cost, and mold is made to safeguard and repair a die conveniently, realizes reduction use cost.
Oil return pipe core_pulling pole 534, oil return pipe shaped insert 535, oil return pipe upper mold section 512 and oil return pipe female die 554 are real
The molding for having showed oil return pipe simplifies the structure of mold.
Sliding split cast mounting and pneumatic split cast mounting realize bottom of the pot side form core 52 and bottom of the pot oil return side form core 53 respectively
Divide mould.
The connection hole forming for connecing oil pipe bottom is realized using intercommunicating pore core_pulling pole 553, avoids secondary operation, is realized primary
Molding, reduces the production cost of bottom of the pot.
Since mold core intensity is high, high precision machining, bottom of the pot side form core 52 and 53 activity of bottom of the pot oil return side form core are inserted in bottom of the pot
Accurate positioning is realized in side form core slot 513, ensures the stabilization of cavity.
If using two half modules and bottom of the pot lower mold core 55 coordinated, need to process precision in cope plate 2 and lower template 3
Higher locating slot or the high-precision positioning device of installation, avoid position in injection moulding process from shifting, lead to mold knot in this way
Structure is complicated, and is got higher to the intensity requirement of cope plate 2 and lower template 3, and cope plate 2 and the volume and weight of lower template 3 are equal
Larger, material cost is got higher, and processing cost greatly improves.
Opening sequence by controlling mold realizes demoulding, simplifies the structure of mold, reduces the use of auxiliary device.
Sliding panel 541 and sliding slot cover board realize the fixation of connecting seat Loose core block 54.Sliding slot cover board prevents connecting seat Loose core block
54 eject in clamping process middle slide plate slot 16.
Upper die holder 1 rises, and upper die holder 1 drives connecting seat Loose core block 54 to rise by sliding panel 541, connecting seat Loose core block 54
It is extracted out from connecting seat, the sliding in the skateboard slot 16 of upper die holder 1 of sliding panel 541 realizes that the inclination of connecting seat Loose core block 54 is taken out
Go out.
Connecting seat Loose core block 54 is slidably matched with core pulling block 24, realizes lifting and the guiding of connecting seat Loose core block 54.By
It is easy to process in 24 small volume of core pulling block, processing cost can be reduced, the inclined hole of the machining high-precision on cope plate 2 is avoided,
So that the frictional force that inclined lift generates is born by core pulling block 24 simultaneously, avoid tiltedly taking out hole by connecting seat and bear, extends connecting seat
Tiltedly take out the service life in hole, the stability for reducing maintenance time, reducing use cost, improving mold.
Inclined guide follows cope plate 2 to rise, and inclined guide pushes side form sliding block to the both sides of mold, and side form sliding block drives pot
Bottom side mold core 52 and bottom of the pot oil return side form core 53 detach.
When cope plate 2 declines molding, the indentation slope driving sliding bevel of cope plate 2, side form sliding block is slided to mould inside
Dynamic, bottom of the pot side form core 52 and bottom of the pot oil return side form core 53 mold.
If upper die holder 1 cannot first rise, connecting seat Loose core block 54 and flowline core_pulling pole 542 can draw bad bottom of the pot, pass through
Mold the rise successively that order controller ensures upper die holder 1 and cope plate 2.
