Specific embodiment
Referring to Fig.1, Fig. 2, it is preceding the utility model discloses a kind of no thimble core-pulling type mold, including preceding mould 1 and rear mold 2
Lifting mould bases 3 is equipped between mould 1 and rear mold 2, which is equipped with forming core 1 and can slide on lifting mould bases 3
Forming core 25, the preceding mould 1 are equipped with preceding forming tank (not showing in figure)；The rear mold 2 is equipped with rear forming tank (in figure
Do not show), the forming core 1 and forming core 25 are located at preceding forming tank after connecting and rear forming tank close up after formed at
In type chamber, plastic product, the liter are formed in the plastics injection moulding core 1 and forming core 25 of thawing and the gap of forming cavity
It drops mould bases 3 and is equipped with driving unit 6 and sliding block 7, driving unit 6 is oil hydraulic cylinder, and the sliding block 7 and forming core 25 and driving are single
Member 6 is fixedly connected, i.e., sliding block 7 is connect with the piston rod of forming core 25 and oil hydraulic cylinder simultaneously, thus oil hydraulic cylinder can pass through promotion
Sliding block 7 and drive forming core 25 to slide, the lifting that jack up of mould bases 3 can will be gone up and down by being equipped between the lifting mould bases 3 and rear mold 2
The specific structure that mechanism, forming core 1 and forming core 25 connect is: being equipped with positioning column in the forming core 25 and (shows in figure
Show), it is equipped with the location hole (showing in figure) cooperate with positioning column in the forming core 1, is convenient for connecting in this way, Er Qiebian
In when forming core 25 exits, positioning column can also exit simultaneously.
As shown, the specific structure of the lifting mould bases 3 is: the rectangular side support plate 31 being oppositely arranged including two,
Fixed plate 1 and fixed plate 2 33 are equipped between side support plate, side support plate and fixed plate one and fixed plate two surround rectangle,
The fixed plate one is equipped with slide opening, and the forming core 25 is slidably matched with the slide opening, and the fixed plate two is equipped with card slot
34, the end of the forming core 1 is stuck in card slot 34, and the card slot 34 is V-shaped groove, is convenient in this way by forming core 25 and is produced
Product take out, and the sliding block 7 is positioned at plate supported on both sides between, and when injection molding, forming core 1 passes through sliding block 7 with 25 one end of forming core and pushes up
Firmly, the other end is blocked by card slot 34 to fixed.The specific structure that sliding block 7 slides is: the side support plate end is equipped with
Link block 35, and the inner sidewall of side support plate is equipped with semicircle sliding slot, is equipped with slide bar 36, the half card of slide bar 36 in semicircle sliding slot
Enter in semicircle sliding slot, the other half is exposed at outside semicircle sliding slot, and the sliding block 7 is connect with one end of slide bar 36, and slide bar 36 is located at cunning
The both ends of block 7, sliding block 7 are connect by pin with slide bar 36, and the piston rod of the oil hydraulic cylinder is connected by link block 35 and slide bar 36
It connects, to connect with sliding block 7, the advantages of above structure is structure manufacture simply easy to process, if bored in side support plate
Not only manufacture difficulty is high for slide opening, but also sliding block 7 cannot directly be connect with slide bar 36 leads to that structure is complicated and at high cost, Er Qie
Groove milling is then much easier in side support plate, and the both ends of sliding block 7 can directly be connect with slide bar 36, simplify structure, improves
Reliability.
As shown, the elevating mechanism includes spring (not showing in figure), the traveller 8 being fixed in rear mold 2 and sets
The through-hole being placed on lifting mould bases 3, the through-hole is interior to be equipped with the sliding sleeve 9 matched with traveller 8, and the rear mold 2 is equipped with mounting hole
One, the lifting mould bases 3 is equipped with mounting hole two, and the spring one end is located in mounting hole one and the other end is located at mounting hole two
It is interior, above structure using spring as jack up go up and down mould bases 3 power, be not only simple in structure and it is at low cost, maintenance is simple
Single, good reliability.
It further include jam plate 10, preceding mould 1, lifting mould bases 3 and rear mold 2 are fixed as one by jam plate 10.
The summary of this structural principle；Before injection molding, preceding mould 1, lifting mould bases 3 and rear mold 2 are integrated by we, pass through jam plate
10 lock screws are fixed, and again dismantle jam plate 10 after integrally loading onto injection molding machine, and injection molding machine can be by preceding mould 1, lifting mould bases 3 and rear mold
2 lockings are integrated, and after injection molding, mould 1 is separated before injection molding machine drives, while spring is jacked up mould bases 3 is gone up and down, the then work of oil hydraulic cylinder
Stopper rod, which stretches out, drives link block 35 mobile, thus mobile with movable slider 7 by slide bar 36, sliding block 7 drives forming core 25 in slide opening
Then interior movement is by hand taken out forming core 1 in product and product together to exit from the product of injection molding, then will be at
Type core 1 exits, to complete the process of depanning.
