Elastic force pushes jacking block to be displaced outwardly, and then can assist the effect of jacking positioning groove, that is, is conducive to quick parting and takes off
Mould improves working efficiency.
Further, the length that the jacking block is pierced by the part of the jacking slot is equal to the jacking block and is located at the top
The bottom of the part in slot is risen at a distance from the jacking trench bottom, which can guarantee that positioning groove and positioning convex platform cooperate
When, positioning groove and positioning convex platform completely attach to, and do not generate gap, will not have an impact to injection molding effect.
Further, the central axis weight of the central axis of the type chamber vertical direction and the positioning convex platform vertical direction
It closes, when which is conducive to injection molding, the force localization of type chamber and type core is prevented in the center of positioning convex platform and positioning groove
Only it generates situations such as dislocation.
Further, the cross section of the positioning convex platform is isosceles trapezoid, and the angle on bevel edge and bottom edge is 50 ° -70 °,
The angular range both can be convenient positioning convex platform and positioned or be can be convenient quick separating between positioning convex platform and positioning groove.
The utility model has the beneficial effects that
The positioning pin that the utility model injection mold solves general injection mold is easy disconnected in dynamic model and cover half injection molding molding
It splits, and then dynamic model and cover half can not be positioned completely, simultaneously because die joint is larger, increase the workload of pincers worker, drop
The problem of low working efficiency, replaces the setting of positioning pin and locating slot by the setting of positioning convex platform and positioning groove, can be with
It solves the problems, such as dynamic model and cover half be positioned and be limited due to positioning pin is not only thin but also length is easily broken off, and due to positioning
Boss and cover half are integrally formed, and ensure that the intensity of positioning convex platform, make to position and restriction effect is more prominent.Positioning convex platform simultaneously
Upper surface area be less than lower surface area, reduce the area of die joint, reduce the workload of pincers worker, improve work
Make efficiency.
It drives latch segment to move down by drive rod, is adjacent to latch segment with positioning groove, and then promote positioning groove
Dislocation or dynamic model and cover half occur when so as to prevent dynamic model and cover half mold-closing injection for coupling mechanism force when cooperating with positioning convex platform
Between there is a situation where gap and cause to be molded ineffective, improve injection-molded finished effect.
When positioning groove and positioning convex platform can be made to cooperate i.e. molding by the setting of jacking apparatus, jacking block is moved to top
It rises in slot, and compressed spring is made be in compressive state, when positioning groove and positioning convex platform are far from mould is divided, compressed spring generation

Rate.The central axis of 22 vertical direction of type chamber is overlapped with the central axis of 21 vertical direction of positioning convex platform, which is conducive to infuse
When modeling, the force localization of type chamber 22 and type core 12 prevents its generation in the center of positioning convex platform 21 and positioning groove 11
Situations such as dislocation.The cross section of positioning convex platform 21 is isosceles trapezoid, and the angle on bevel edge and bottom edge is 50 ° -70 °, the angle model
Enclosing both can be convenient positioning convex platform 21 and is positioned or be can be convenient quick separating between positioning convex platform 21 and positioning groove 11.
Embodiment one
As shown in Fig. 2, the left and right sides of positioning groove 11 is symmetrical arranged locking device 6, locking device 6 includes latch segment
61, channel 62 and drive rod 63 are locked, locking channel 62 is set to the outside of positioning groove 11 and along the length direction of dynamic model 1
Distribution, latch segment 61 be set to locking channel 62 in, and 61 one end of latch segment with locking channel 62 inner wall be bonded, the other end and
The side wall of positioning groove 11 is bonded, and drive rod 63 is set to the upper end of latch segment 61 and latch segment 61 can be driven along locking channel 62
It moves up and down.Drive rod 63 is threaded rod, and the threaded hole of setting with shaft is run through on dynamic model 1 and dynamic model pedestal 3
14.The central axis of 63 vertical direction of drive rod is overlapped with the central axis of 61 vertical direction of latch segment.It is driven by drive rod 63
Dynamic latch segment 61 moves down, and is adjacent to latch segment 61 with positioning groove 11, and then promotes positioning groove 11 and positioning convex platform 21
Coupling mechanism force when cooperation occurs to deposit between dislocation or dynamic model 1 and cover half 2 when so as to prevent 2 mold-closing injection of dynamic model 1 and cover half
Cause to be molded ineffective situation in gap, improves injection-molded finished effect.
Embodiment two
As shown in Figure 3-4, on the basis of example 1, jacking is symmetrical arranged at left and right sides of 21 upper impression 22 of positioning convex platform
Device 7, jacking apparatus 7 include jacking slot 71, jacking block 72 and compressed spring 73, and jacking slot 71 is set to the outside of type chamber 22
And be distributed by the upper surface of positioning convex platform along the length direction of cover half 2, jacking block 72 is that one end is set in jacking slot 71 separately
One end is pierced by the T-block of jacking slot 71, and the diameter for jacking one end that block 72 is pierced by jacking slot 71 is less than in jacking slot 71
One end diameter, while jack block 72 can along jacking slot 71 length direction be moved, compressed spring 73 connection jacking block
72 are located at one end in jacking slot 71 and the bottom of jacking slot 71.The length that jacking block 72 is pierced by the part of jacking slot 71 is equal to top
The bottom for the part that block 72 is located in jacking slot 71 is risen at a distance from jacking 71 bottom of slot.It can be with by the setting of jacking apparatus 7
When positioning groove 11 and positioning convex platform 21 being made to cooperate i.e. molding, jacking block 72 is moved in jacking slot 71, and makes compressed spring 73
In compressive state, when positioning groove 11 and positioning convex platform 21 are far from mould is divided, compressed spring 73 generates elastic force, pushes jacking
Block 72 is displaced outwardly, and then can assist the effect of jacking positioning groove 11, that is, is conducive to quick parting and demoulding, improves work
Efficiency.
