Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Mode, the present invention will be further described in detail.
The utility model first embodiment provides a kind of synchronous reset injection mold, as shown in Fig. 1 to 7, including preceding mould
Core 1 and rear mold core 2 form the injection die cavities for injection molding product 3 when molding, between the preceding mold core 1 and rear mold core 2；
The injection mold further includes the first jacking block 4, the second jacking block 5 and line position seat 6, and first jacking block 4 and second pushes up
Block 5 is located at the both sides in 6 moldings of the line position seat/die sinking direction and can be moved along molding or molding direction；First top
It includes the first skew wall 41 that block 4, which has the first ejection part close to the line position seat 6, first ejection part,；Second jacking block 5
With the second ejection part close to the line position seat 6, second ejection part includes and first skew wall, 41 inclined direction phase
The second same skew wall 51；The line position seat 6 is equipped with the first limit hole 61 and the second limit hole 62, and first limit hole 61 has
There are the first sliding wall 611 and the first limited wall 612 being oppositely arranged, first sliding wall 611 and 41 phase of the first skew wall
Cooperation；Second limit hole 62 has the second sliding wall 621 and the second limited wall 622 being oppositely arranged, second sliding
Wall 621 is matched with second skew wall 51；
Mold core 2 is connect with first jacking block 4 after described, and first jacking block 4 is ejected towards molding direction to described first
Skew wall 41 contradicts when on first sliding wall 611 completely, and the rear mold core 2 is driven to be molded with the preceding mold core 1；First top
When block 4 continues to eject to molding direction, the line position seat is pushed by the mating reaction of the first skew wall 41 and the first sliding wall 611
6 move along vertical molding/die sinking direction, until the first ejection part contradicts on first limited wall 612, and the second sliding wall
Second skew wall 51 described in 621 faces；After mold core 2 resets after first jacking block 4 drives, second jacking block 5 is moved towards die sinking direction
After being contradicted on the second sliding wall 621 to second skew wall 51, second jacking block 5 is slided by the second skew wall 51 and second
The mating reaction of wall 621 pushes the line position seat 6 to reset, until the second ejection part contradicts on second limited wall 622.
It should be noted that the connection type between first jacking block 4 and rear mold core 2 can be directly fixedly connected,
Can also be to be connected by other component.
The size of first limit hole 61 is more than the first ejection part size；Second limit hole, 62 size is more than
The second ejection part size, so that the first jacking block 4 and the second jacking block 5 can be limited in the first limit hole 61 and second respectively
It is relatively moved in hole 62.
Further, there is the line position seat 6 third skew wall 63, the third skew wall 63 to have with first sliding wall 61
There are identical inclined direction, the opposite end activity that the preceding mold core 1 molds one end to be flexibly connected with third skew wall 43, the line position
When seat 6 moves, the preceding mold core 1 is located at the different height of the third skew wall 63.This programme is by preceding mold core 1 and line position seat 6
An overall structure is connected into, injection mold structure is simplified.Pass through the setting of third skew wall so that the position of preceding mold core is kept
It is fixed.
Steps are as follows for the die sinking and molding of the synchronous reset injection mold of the present embodiment：
S1, with reference to figure 1, Fig. 2, under initial die opening state, the first jacking block 4 and the second jacking block 5 are located at line position seat 6 and open
The both sides in mould/molding direction, wherein the first sliding wall 611 of 41 the first limit hole of face 61 of the first skew wall, the second jacking block 5 is just
To the second limit hole 52 close to 522 side of the second limited wall；
S2, it is contradicted when on the first sliding wall as shown in figure 3, ejecting 4 to the first skew wall of the first jacking block to molding direction, the
Mold core 2 forms the injection die cavities for injection molding product 3 with the molding of preceding mold core 1 after one jacking block 4 drives；
S3, with reference to figure 4, continue to molding direction eject the first jacking block 4, line position seat 6 conflict effect under, the first jacking block
4 push the line position seat 6 to be moved along vertical molding/die sinking direction by the first skew wall with the mating reaction of the first sliding wall, directly
It contradicts to the first ejection part and stops when on first limited wall；At this point, the second skew wall described in the second sliding wall face；At this
In step, due to being contradicted by the first sliding wall, the first jacking block 4 does not move, in the moving process of line position seat 6, third
Skew wall is moved relative to mold core 1, so that the holding position in injection mold of preceding mold core 1 is fixed；
S4, with reference to figure 5, move mold core 2 and preceding mould after the first jacking block 4 makes its reset, the first jacking block 4 drive to die sinking direction
Core 1 molds, and takes out injecting products；
S5, with reference to figure 6, contradicted on the second sliding wall to die sinking direction ejection 5 to the second skew wall of the second jacking block；
S6, with reference to figure 7, continue to die sinking direction eject the second jacking block 5, line position seat 6 conflict effect under, the second jacking block
5 push the line position seat 6 to reset by the mating reaction of the second skew wall and the second sliding wall, until the second ejection part is contradicted in institute
Stop movement when stating on the one or two limited wall, at this point, the first skew wall described in the first sliding wall face；
S7, make its reset, return to step S1 to the second jacking block 6 of molding direction movement.
The present embodiment plays position-limiting action, so as to avoid rear by the conflict of the first jacking block of line position seat pair to clamping process
It collides between mold core and preceding mold core；And injection mold can realize the synchronous reset to each component, to simplify injection molding
Step improves injection molding precision and production efficiency.
The foregoing is merely the better embodiments of the utility model, are not intended to limit the utility model, it is all
It is new to should be included in this practicality for all any modification, equivalent and improvement made by within the spirit and principles of the utility model etc.
Within the protection domain of type.
