Bottom of the pot upper mold core 51, attachment base 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 515 are combined shape
At bottom of the pot type chamber, one-pass molding is realized.
Attachment base Loose core block 54 is obliquely installed, and be slidably installed fall in love with it is conveniently stripped on die holder 1.In attachment base Loose core block 54
The one-pass molding of attachment base and flowline is realized equipped with flowline core_pulling pole 542.Flowline core_pulling pole 542 is mounted on attachment base
Keep structure simple, the difficulty of processing for reducing attachment base 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.
Fixation hole core pulling column 522 and bottom of the pot side form core 52, which are integrally formed, avoids the surface of fixation 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 515 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, machining accuracy is high, 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, the stabilization of guarantee type chamber are realized in side form core slot 513.
If cooperated using two half modules and bottom of the pot lower mold core 55, 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 gets 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 attachment base Loose core block 54.Sliding slot cover board prevents attachment base Loose core block
54 eject in clamping process middle slide plate slot 16.
Upper die holder 1 rises, and upper die holder 1 drives attachment base Loose core block 54 to rise by sliding panel 541, attachment base Loose core block 54
It is extracted out from attachment base, sliding panel 541 slides in the skateboard slot 16 of upper die holder 1 realizes that the inclination of attachment base Loose core block 54 is taken out
Out.
Attachment base Loose core block 54 is slidably matched with core pulling block 24, realizes the lifting and guiding of attachment base Loose core block 54.By
It is easy to process in 24 small volume of core pulling block, processing cost can be reduced, the oblique of on cope plate 2 machining high-precision is avoided
Hole, while the frictional force for generating inclined lift is born by core pulling block 24, is avoided tiltedly taking out hole receiving by attachment base, is extended connection
Seat tiltedly takes 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 two 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 separate.
When the decline molding of cope plate 2, 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, attachment base Loose core block 54 and flowline core_pulling pole 542 can draw bad bottom of the pot, pass through
It is opened the successively rise that order controller guarantees upper die holder 1 and cope plate 2.
