Description
Technical field
Production auto parts machinery injection mold field is the utility model is related to, the preceding mould of especially a kind of anti-injection mold is slided
Block rollback system.
Background technology
Front mold slide in injection mold, it is molded position usually in the appearance of product, the clamp segment difference formed
Quality can have a strong impact on product quality, front mold slide typically by hydraulic oil cylinder driving, first completes core pulling action before die sinking, its lock
Power is from one side slide block of increase.When the shaping area of front mold slide is larger, rollback phenomenon occurs in locking sliding block, leads
Cause product clip line segment difference unqualified.In order to avoid the rollback phenomenon of front mold slide, there are two schemes at present：First, in front mold slide
Lower increase bullet block, second, using twice-die-opening structure.
Increase bullet block under front mold slide, effect is unstable, when shaping area is larger or injection pressure is big, still occurs
Rollback phenomenon.
Twice-die-opening structure is three template dies, and preceding mould increases a die sinking action, and die cost is high, and action is complicated, product life
Produce cycle length.
Utility model content
The utility model aims to solve the problem that above mentioned problem, there is provided a kind of front mold slide rollback system of anti-injection mold, it
During injection, twice-die-opening structure is not used, action is simple and reliable, is applicable front mold slide core pulling in any case, can effectively prevent
The rollback phenomenon of limited slip block, simple in construction, manufacturing cost is low, and the technical scheme that it is used is as follows：
A kind of front mold slide rollback system of anti-injection mold, it is characterised in that including：Oil cylinder, locking sliding block, T-shaped piece
And front mold slide, the piston rod of the oil cylinder is connected with locking sliding block so that locking sliding block makees horizontal rectilinear motion, described T-shaped
Block and front mold slide Joint, the bottom of the locking sliding block have an inclined T-slot, and described T-shaped piece is located in T-slot and can
Slided in T-slot, described T-shaped piece is integrally formed by transverse part and longitudinal portion, the top surface of the T-slot to T-slot bottom surface
The thickness of transverse part of the distance more than T-shaped piece, the front mold slide makees vertical lines motion under locking sliding block driving, before described
There is the horizontal backstop being engaged with locking platform to put down for locking platform formed with level on mode slider, the locking sliding block
Face.
On the basis of above-mentioned technical proposal, when T-shaped piece of transverse part bottom surface is closely attached on T-slot bottom surface, described T-shaped piece
The horizontal range of top surface to T-slot top surface is L2, and the length of the locking platform is L1, and the L2 is more than or equal to L1.
The utility model has the following advantages that：When it is molded, twice-die-opening structure is not used, and action is simple and reliable, is applicable
Front mold slide core pulling in any case, can effectively anti-limited slip block rollback phenomenon, simple in construction, manufacturing cost is low.

Embodiment
The utility model is described in further detail with example below in conjunction with the accompanying drawings：
Embodiment of the present utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning
Same or similar element is represented to same or similar label eventually or there is the element of same or like function.Below by ginseng
The embodiment for examining accompanying drawing description is exemplary, is only used for explaining the utility model, and it is not intended that to of the present utility model
Limitation.
, it is necessary to which explanation, unless otherwise clearly defined and limited, term " are pacified in description of the present utility model
Dress ", " connected ", " connection " should be interpreted broadly, for example, it may be fixedly connected or be detachably connected, or integratedly
Connection；Can be joined directly together, can also be indirectly connected by intermediary.For the ordinary skill in the art,
Concrete meaning of the above-mentioned term in the utility model can be understood with concrete condition.
As shown in Fig. 1 to Fig. 5 and Figure 10, a kind of front mold slide rollback system of anti-injection mold of the present embodiment, it is special
Sign is, including：Oil cylinder 1, locking sliding block 2, T-shaped piece 3 and front mold slide 4, piston rod and the phase of locking sliding block 2 of the oil cylinder 1
Connection causes locking sliding block 2 to make horizontal rectilinear motion, described T-shaped piece 3 and the Joint of front mold slide 4, the bottom of the locking sliding block 2
Portion has inclined T-slot 5, and described T-shaped piece 3 is located in T-slot 5 and can be slided in T-slot 5, and described T-shaped piece 3 by transverse direction
Portion 30 and longitudinal portion 31 are integrally formed, and the top surface of the T-slot 5 is more than T-shaped piece 3 of transverse part 30 to the distance of the bottom surface of T-slot 5
Thickness, the front mold slide 4 makees vertical lines motion under locking sliding block driving, formed with level on the front mold slide 4
Locking platform 6, the locking sliding block 2 has the horizontal stop plane 7 that is engaged with locking platform 6.Front mold slide 4 slides
Before being connected in the chute of mould insert.
Preferably, when T-shaped piece 3 of transverse part bottom surface is closely attached on 5 bottom surface of T-slot, described T-shaped piece 3 of top surface to T-slot
The horizontal range of 5 top surfaces is L2, and the length of the locking platform 6 is L1, and the L2 is more than or equal to L1.It can so avoid locking flat
Motion of the platform 6 to locking sliding block produces interference.
The plane of locking platform is vertical with the direction of motion of front mold slide, horizontal locking platform and stop plane during matched moulds
Locking effect is played in 7 contacts, is not in that front mold slide rollback phenomenon occurs because pressure acts on, the product clip line segment difference of production is closed
Lattice and steady quality；
As shown in Figure 6 and Figure 7, during die sinking, oil cylinder 1 retracts, and locking sliding block 2 moves to left, because T-shaped piece 3 with locking sliding block 2
There is gap H between T-slot 5, contacted after the rollback L2 of locking sliding block 2 with T-shaped piece 3 of spigot surface (bottom surface), continued before retreating driving
Mode slider 4 completes core pulling action.Because L2 is more than or equal to L1, therefore spigot surface (bottom after 2 rollback L2 of locking sliding block with T-shaped piece 3
Face) contact when, the extension line on the inclined-plane 8 on the right side of stop plane 7 will not produce friendship with locking platform 6 and stay, therefore locking can be avoided flat
Motion of the platform 6 to locking sliding block produces interference.
As shown in Figure 8 and Figure 9, during matched moulds, oil cylinder 1 moves ahead, and locking sliding block 2 contacts after moving L2 with T-shaped piece 3, before continuation
Row driving front mold slide 4 matched moulds is in place.
The utility model is illustrated by way of example above, but the utility model is not limited to above-mentioned specific implementation
Example, all scopes that the requires of the utility model protection is belonged to based on any changes or modifications that the utility model is done.
