When the back-off stroke of the injection molding product is larger, the back-off stroke of the inclined top is longer, the inclination of the inclined top is larger, the length of the inclined top is longer, the processing difficulty is higher, the inclined top is easy to deform and bend, the inclined top with larger inclination is easy to have ejection abnormal sound, even the inclined top is broken and easy to eject unbalance, and the batch production of the product is influenced.
Disclosure of Invention
An object of the utility model is to provide a take out structure behind ejecting smooth and easy, the simple injection mold inner slide of processing technology.
In order to achieve the above object, the technical solution of the present invention is:
the utility model relates to an injection mold inner slide block rear-drawing structure, which comprises a fixed template, a supporting plate, a movable template, an inner slide block, a T-shaped block, a limiting screw, a supporting plate spring, a nylon pull buckle, a limiting rod, a top plate and a top plate spring; the fixed template is arranged opposite to the supporting plate, the supporting plate is abutted against the movable template, the lower end of the T-shaped block is fixed on the movable template, the upper part of the T-shaped block penetrates through the supporting plate, the inner side wall of the inner sliding block is slidably connected to the upper part of the T-shaped block in a groove block matching mode, and the bottom surface of the outer side of the inner sliding block is abutted against the supporting plate so as to jack up the inner sliding block by the supporting plate separated from the movable template; the nylon pull buckle is arranged between the fixed template and the supporting plate, the lower end of the limiting screw is fixed on the movable template, the upper countersunk head of the limiting screw movably penetrates through the trapezoidal hole of the supporting plate, and the supporting plate spring is arranged between the supporting plate and the movable template and is sleeved in the middle of the limiting screw; the lower end of the limiting rod is fixed on the top plate, the upper portion of the limiting rod penetrates through the movable template, the supporting plate and the limiting block at the top end of the limiting rod to penetrate out of the top surface of the supporting plate, and the top plate spring is sleeved on the lower portion of the limiting rod and two ends of the top plate spring respectively abut against the movable template and the top plate.
The two inner sliding blocks are respectively connected to the inclined planes on the two sides of the upper part of the T-shaped block in a sliding mode in a matched mode of the groove blocks.
After the scheme is adopted, because the utility model discloses during the die sinking, fix the T type piece on the movable mould board and drive interior slider, realize taking out behind the interior slider, it is ejecting that the layer board drives the roof through the gag lever post, takes out behind the interior slider after the board continues ejecting, makes the product separately with the mould completely. The utility model discloses a take out structural style behind the interior slider and realize the product drawing of patterns, have the ejecting smooth and easy, the simple, lower advantage of cost of batch production.
The invention will be further described with reference to the accompanying drawings and specific embodiments.

FIG. 1 is a state diagram of the mold assembly of the present invention;
FIG. 2 is a state diagram of the mold opening of the present invention;
fig. 3 is a state diagram of the ejection start of the present invention;
fig. 4 is a state diagram of the present invention in full ejection.
Detailed Description
As shown in fig. 1-4, the utility model relates to a take out structure behind slider in injection mold, including fixed die plate 1, layer board 2, movable mould board 3, interior slider 4, T type piece 5, stop screw 6, layer board spring 7, nylon draw knot 8, gag lever post 9, roof 10, roof spring 11.
The fixed die plate 1 is arranged opposite to the supporting plate 2, the supporting plate 2 is abutted against the movable die plate 3, the lower end of the T-shaped block 5 is fixed on the movable die plate 3, the upper part of the T-shaped block 5 penetrates into the supporting plate 2, the inner side wall of the inner slide block 4 is in sliding connection with the upper part of the T-shaped block 5 in a groove block matching mode, and the outer bottom surface of the inner slide block 4 is abutted against the supporting plate 2 so that the supporting plate 2 separated from the movable die plate 3 can jack up the inner slide block 4 and separate the product 100 from the die cavity; the nylon pull buckle 8 is arranged between the fixed template 1 and the supporting plate 2, the lower end of the limit screw 6 is fixed on the movable template 3, the upper countersunk head 61 of the limit screw 6 movably penetrates through the trapezoidal hole 21 of the supporting plate 2, and the supporting plate spring 7 is arranged between the supporting plate 2 and the movable template 3 and is sleeved in the middle of the limit screw 6; the lower extreme of gag lever post 9 is fixed on roof 10, and the stopper 91 that gag lever post 9 upper portion passed movable mould board 3, layer board 2 and gag lever post 9 top is worn out layer board 2 top surface, and roof spring 11 cup joints the lower part of gag lever post 9 and the both ends of roof spring 11 and leans on respectively in the top of movable mould board 3 and roof 10.
In this embodiment, there are two inner sliding blocks 4, and the two inner sliding blocks 4 are respectively slidably connected to the two side slopes of the upper portion of the T-shaped block 5 in a way of slot block fit.
The utility model discloses a theory of operation:
