As shown in Figure 1, the double inner side core-drawing mechanisms of dynamic model drive formula cover half, including type core mold insert block 7, type chamber mold insert block 6 are described
Type chamber mold insert block 6 is set in cover half 11, and the cover half 11 is failure to actuate in demoulding；The type core mold insert block 7 is set to dynamic model 9
In, dynamic model 9 is acted far from cover half when demoulding.The interface of the cover half 11 and dynamic model 9 is die joint 10, after the completion of injection molding,
Dynamic model 9 is separated at die joint 10 with cover half 11.When demoulding, dynamic model 9 separates at die joint 10 with cover half 11, the type
Core mold insert block 7 follows dynamic model 9 to act together, and the type chamber mold insert block 6 is failure to actuate together with cover half 11.
It is provided with type core mold insert block 7 in the dynamic model 9, is provided in the dynamic model 9 and type core mold insert block 7 several perforative
Hole is provided with elongated thimble 8 in the perforative hole, when the thimble 8 is used to demould by product from dynamic model 9 type chamber or
The separation of person's type core.Corresponding to type chamber mold insert block 6 is provided at the position of type core mold insert block 7 in the cover half 11, the type chamber is inlayed
Part block 6 is used to form the shape of plastic 17.
6 two sides of type chamber mold insert block are provided with perforative first hole 15, and 7 two sides of type core mold insert block correspond to first
Perforative second hole 16 is provided at the position in hole 15, first hole 15 is identical with 16 size of the second hole, and described first
Hole 15 and the second hole 16 are to communicate and coaxial circular hole.Geosynclinal block drive block 5, institute are inserted in first hole 15 and the second hole 16
Stating geosynclinal block drive block 5 can slide in first hole 15 and the second hole 16, for the size for guaranteeing plastic 17, the geosynclinal block driving
Block 5 and the first hole 15 and the second hole 16 are small―gap suture cooperation, and the shift in position of geosynclinal block drive block 5 is to 17 ruler of plastic when preventing from being molded
Very little influence.Side of the geosynclinal block drive block 5 in cover half 11 is fixedly connected with sliding geosynclinal block 3, sets on the sliding geosynclinal block 3
It is equipped with the first slot 14,14 cross section of the first slot slidably connects angle ejector rod 4, institute in interior big outer small in first slot 14
State that angle ejector rod 4 is cylindrical, one end of the angle ejector rod 4 is provided with protrusion, and the protrusion is for shaping the recessed of 17 inner wall of plastic
Slot or hole.Be provided with the first inclined hole 13 on the type chamber mold insert block 6, first inclined hole 13 be located at two first holes 15 it
Between, the angle ejector rod 4 is inserted in first inclined hole 13, and the angle ejector rod 4 can slide in first inclined hole 13, demoulding
Shi Suoshu angle ejector rod 4 moves in the first inclined hole 13 along 9 direction of symmetrical axial dynamic model of first inclined hole 13.
Elastic device 1,1 other end of the elastic device connection are connected on the sliding end face of the geosynclinal block 3 far from dynamic model 9
It hides oneself block 2.The elastic device 1 is spring, and the spring is set among the circular hole of the block 2 of hiding oneself in the cover half 11, when
After dynamic model 9 is separated with cover half 11, spring is still connected with the sliding geosynclinal block 3, and is in compressive state.The spring is for moving
When mould 9 is separated with cover half 11, to sliding geosynclinal block 3 play auxiliary pushing, prevent the sliding geosynclinal block 3 in action process with it is attached
Near-end part is stuck；Auxiliary angle ejector rod 4 resets from when cover half 11 and dynamic model 9 are combined.
It is further improved compared to above scheme, first slot is T-slot, and the T-slot is through sliding geosynclinal block
3, the end of the angle ejector rod 4 is located in the T-slot, the cross-sectional shape of the end shape of the T-slot and the T-slot
It is adapted, so 4 end of the angle ejector rod will not be separated from T-slot.
It is further improved compared to above scheme, the sliding geosynclinal block 3 has the first angle with the die joint 10, described
First angle is 10 ° -20 °.
It is further improved compared to above scheme, the angle of the sliding geosynclinal block 3 and the die joint 10 is 15 °.
It is further improved compared to above scheme, is provided with skewback 12, the skewback between described two sliding geosynclinal blocks 3
12 close to it is described sliding geosynclinal block 3 end face be inclined-plane, the angle on the inclined-plane is corresponding with first angle, when angle ejector rod 4
When moving in the first inclined hole 13 to the direction of dynamic model 9, the end of the angle ejector rod 4 is also being driven along T-slot to far from geosynclinal block
The direction of motion block 5 moves, and the skewback 12 can prevent the angle ejector rod 4 from separating from T-slot.
Further improved compared to above scheme, the sliding geosynclinal block 3 by screw thread and the geosynclinal block drive block 5 into
Row is fixedly connected, and to guarantee fastening and not turning to, at least two screws that can be used will be fixed.
It is further improved compared to above scheme, the type core mold insert block 7 is provided with far from the end face two sides of dynamic model 9
One notch, corresponding to being provided with the first protrusion at the position of the first notch on the geosynclinal block drive block 5.When dynamic model 9 acts, move
The type core mold insert block 7 on mould 9 acts together with dynamic model 9, and drives the first protrusion to follow geosynclinal block drive block 5 by notch
Dynamic model 9 acts together.
The working principle of the invention is simply illustrated below, when demoulding, dynamic model and cover half are in 10 parting of die joint, slot
Block drive block 5 is as dynamic model is together far from cover half, and geosynclinal block drive block 5 drives sliding geosynclinal block 3 to move together, and end drives in geosynclinal block
For the angle ejector rod 4 slided in the T-slot of block 3 along the first inclined hole 13 together far from cover half, angle ejector rod 4 is same close to one end of plastic 17
It walks to the movement of plastic middle, until inner wall groove or the hole of plastic 17 are left in 4 end of angle ejector rod completely, then will be moulded with thimble 8
Part 17 is detached from from type core mold insert block 7 can be taken off plastic 17.
