Convex portion is provided with, the second sliding block both ends are respectively arranged with projection, and one end projection is recess, and the other end is raised spacing for first
Block；The convex portion is engaged with recess, and the distance between two projection is engaged with the first sliding block and latch segment；Described first slides
The first spring is provided between block and cover half, first spring applies towards the power on the outside of mould to the first sliding block；Described second
Second spring is provided between sliding block and dynamic model, the second spring applies the power towards die inside to the second sliding block.Pass through
The relative slip of one sliding block and the second sliding block, a core pulling step is set to complete the core pulling work of both sides, and the second sliding block
Sliding distance be easily controlled, other structures will not be caused to interfere.
Preferably, being detachably provided with the second limited block on the dynamic model, the second spring is arranged on the second sliding block
Between the second limited block.By dismountable second limited block, the sliding distance of the second sliding block can be further controlled, is adapted to
Different plastic requirement, to choose the possibility that most suitable sliding distance reduces interference.
Preferably, first sliding block carries the first inclined-plane, first limited block carries the second inclined-plane, described
First inclined-plane and the second inclined-plane are engaged with the first inclined-plane and the second inclined-plane respectively towards cover half, the latch segment.In order that
It is more convenient during cooperation, extract out during installation and demoulding during by setting inclined-plane to facilitate latch segment matched moulds.
The utility model compared with the existing technology has advantages below and effect：By set be engaged the first sliding block,
Second sliding block and locking block structure, the demoulding requirement for being adapted to special plastic is allowed to, and two can be completed by a core pulling step
The core pulling work of side, and the sliding distance of the second sliding block is easily controlled, and is suitable for different plastic requirements, it is most suitable to choose
Sliding distance reduce interference possibility.During installation and demoulding when further facilitating latch segment matched moulds by the setting on inclined-plane
Extract out.

Embodiment
The utility model is described in further detail with reference to embodiment, following examples are to the utility model
Explanation and the utility model is not limited to following examples.
Embodiment 1：
As shown in Fig. 1 to 2, the present embodiment is made up of cover half 4, dynamic model 6 and sliding block core-pulling mechanism, wherein sliding block core-pulling mechanism
Including the first sliding block 2, the second sliding block 7 and latch segment 1, latch segment 1 is detachably connected on cover half 4 by the first screw 11, the
One sliding block 2 is provided with convex portion 21 towards the direction of plastic 5, and the side opening that convex portion 21 is used for plastic 5 is molded, and the other end is and latch segment 1
The first inclined-plane 22 being engaged；The both ends of second sliding block 7 are raised, and the projection close to plastic 5 is recess 71, and recess 71 is matched somebody with somebody with convex portion 21
Closing makes plastic 5 form the side opening with in-flanges, and other end projection is the first limited block 72, and the first limited block 72 is provided with and locked
The second inclined-plane 73 that tight block 1 is engaged.Second limited block 9 is detachably connected on dynamic model 6 by the second screw 91, the first sliding block
2 connect cover half 4 by the first spring 3, and the first spring 3 provides logical to the thrust on the outside of mould, the second sliding block 7 for the first sliding block 2
Cross second spring 8 and connect the second limited block 9, second spring 8 provides the thrust to die inside for the second sliding block 7.When the first cunning
When block 2, the second sliding block 7 and the three of latch segment 1 coordinate, distance and the latch segment 1 and first of the limited block 72 of recess 71 and first are slided
The width of block 2 is adapted, and the first sliding block 2 is located at the position for being close to cover half 4, and the second sliding block 7 is located at and is close to the second limited block 9
Position.
During matched moulds, in the presence of latch segment 1, the second sliding block 7 is stuck between the limited block 9 of latch segment 1 and second, and first slides
Block 2 is stuck between latch segment 1 and cover half 4, completes injection.During die sinking, the first sliding block 2 pushing away in the first spring 3 of cover half side
Under power, the inclined-plane on latch segment 1 performs relative motion, and moves to the left, completes the core pulling work in the left side of plastic 5；Latch segment 1
After being separated with the second sliding block 7, the second sliding block 7 moves to the right in the presence of second spring 8, completes the core pulling on the right side of plastic 5
Work, because the limited displacement of the second sliding block 7 will not cause to interfere to other structures, the mould can smoothly core pulling with it is de-
Mould.
