Description

Barb demolding structure

[technical field]

The present invention relates to a kind of mould structure, be specifically related to a kind of barb demolding structure of mould.

[background technology]

The plastic parts of product can use plastic mould to carry out moulding, for example, be the plastic parts such as the shell of electronic product.Due to popularizing of electronic product, also become the problem of broad research for the improvement of plastic mould.

In the time producing plastic cement products, refer to shown in Fig. 1, on the product 10 of Fig. 1, existing barb 11, has again fin 12, and the exit axis of the exit axis of barb 11 and fin 12 is inconsistent.Refer to shown in Fig. 2, the barb demolding structure of prior art uses taper pin 20 to exit this barb 11 conventionally, barb 11 is exited in taper pin 20 lateral movement under the liftout plate active force of mould, but this fin 12 can produce and interfere with taper pin 20, and taper pin 20 cannot be exited, this fin 12 must be revised, if client disagrees with this fin 12 of amendment, mould cannot die sinking, has the product 10 of fin 12 on cannot moulding barb 11 exit axis.

In view of this, be in fact necessary to develop a kind of barb demolding structure, to solve the above-mentioned problem that has the product of fin on cannot moulding barb exit axis.

[summary of the invention]

Therefore, the object of this invention is to provide a kind of barb demolding structure, this barb demolding structure can be molded over the product that has fin on barb exit axis.

In order to achieve the above object, barb demolding structure of the present invention, is applied in mould, has the product of fin on moulding barb exit axis, and taking mould die sinking direction as vertical direction, this barb demolding structure comprises:

Male die core, the fin on its shaped article;

The first slide block, which is provided with the angling hole that is angle of inclination with vertical direction, is provided with Angle Pin and stirs this first slide block movement in this angling hole, and this first slide block is provided with stopper slot;

The second slide block, it is located at the barb on shaped article in male die core, and this second slide block is provided with groove;

Turning arm, its movable being located in male die core, and this turning arm one end extend in described groove, is also fixed with projection on this turning arm, and this projection is stuck in described stopper slot.

Alternatively, described turning arm is L-type, in this turning arm, is provided with rotating shaft, and correspondingly this turning arm is around this rotating shaft motion.

Alternatively, described projection is cylinder, and this cylinder one end is stuck in described stopper slot, and the other end extend in turning arm.

Alternatively, described the first slide block is provided with step surface, and in the time of mould matched moulds, this step surface fits in described turning arm.

Compared to prior art, barb demolding structure of the present invention, by the first slide block movement driven rotary arm rotation, turning arm rotation is stirred the second slide block and is exited the barb on product, and the fin on product is male die core moulding, when the second slide block exits barb, can not produce and interfere with fin, thus moulding on barb exit axis, have a product of fin.

[detailed description of the invention]

Refer to shown in Fig. 3, Fig. 4 and Fig. 5, wherein Fig. 3 has illustrated the schematic perspective view of barb demolding structure of the present invention, and Fig. 4 has illustrated the generalized section of the present invention A-A in Fig. 3, and Fig. 5 has illustrated the generalized section of the present invention B-B in Fig. 3.

In the present embodiment, barb demolding structure of the present invention, is applied in mould, and for there being the product 30 of fin 12 on moulding barb 11 exit axis, taking mould die sinking direction as vertical direction, this barb demolding structure comprises:

Male die core 100, the fin 12 on its shaped article 10;

The first slide block 200, which is provided with the angling hole 210 that is angle of inclination with vertical direction, is provided with Angle Pin 220 and stirs this first slide block movement 200 in this angling hole 210, on this first slide block 200, is also provided with stopper slot 230;

The second slide block 300, it is located at the barb 11 on shaped article 10 in male die core 100, correspondingly in this male die core 100, is provided with spatial accommodation located therein for this second slide block 300, and this second slide block 300 is provided with groove 310;

Turning arm 400, it is rotatably located in male die core 100, correspondingly in this male die core 100, be provided with spatial accommodation located therein for this turning arm 400, and these turning arm 400 one end extend in described groove 310, on this turning arm 400, be also fixed with projection 410, this projection 410 is stuck in described stopper slot 230.

Wherein, described turning arm 400 is L-type, in this turning arm 400, is provided with rotating shaft 420, and correspondingly this turning arm 400 moves around this rotating shaft 420.

Wherein, described projection 410 is cylinder, and for this cylinder and this turning arm 400 are become one, this cylinder one end is stuck in described stopper slot 230, and the other end extend in turning arm 400.

Wherein, described the first slide block 200 is provided with step surface 240, and in the time of mould matched moulds, this step surface 240 fits in described turning arm 400, in the time of mould matched moulds, and auxiliary described turning arm 400 returns of this step surface 240.

Shown in Fig. 6, Fig. 7 and Fig. 8, wherein Fig. 6 has illustrated barb demolding structure of the present invention in the schematic perspective view of die opening state, and Fig. 7 has illustrated the generalized section of the present invention C-C in Fig. 6, and Fig. 8 has illustrated the generalized section of the present invention D-D in Fig. 6.

After mould die sinking, thereby male die core 100 exits the fin 12 on product 10 away from the mother module core of mould, described Angle Pin 220 is stirred (direction shown in the arrow) motion left of described the first slide block 200 simultaneously, when the first slide block 200 moves to left after projection 410 and stopper slot 230 conflicts, projection 410 driven rotary arm 400 under the active force of stopper slot 230 rotates, thereby turning arm 400 rotates counterclockwise and stirs (arrow rightabout) motion to the right of the second slide block 300 around described rotating shaft 420, makes the second slide block 300 exit the barb 11 on product 10.

In the time of mould matched moulds, Angle Pin 220 is stirred the first slide block 200 and is moved right, and the step surface 240 of the first slide block 200 promotes turning arm 400 returns, and turning arm 400 drives the second slide block 300 returns.

Barb demolding structure of the present invention, drive turning arm 400 to rotate by the first slide block 200 motions, turning arm 400 rotations are stirred the second slide block 300 and are exited the barb 11 on product 10, and the fin 12 on product 10 is male die core 100 moulding, the second slide block 300 does not exit and can produce and interfere with fin 12, thus moulding on barb 11 exit axis, have a product 10 of fin 12.
