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

[summary of the invention]

Therefore, the purpose of this utility model is to provide a kind of barb demolding structure, and this barb demolding structure can be molded over the product that fin is arranged on the barb exit axis.

In order to achieve the above object, barb demolding structure of the present utility model, be applied in mould, and the product of fin is arranged on moulding barb exit axis, and take 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 in this angling hole and stirs this first slide block movement, 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, also is fixed with projection on this turning arm, and this projection is stuck in described stopper slot.

Alternatively, described turning arm is L-type, is provided with rotating shaft in this turning arm, 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 this step surface fits in described turning arm when the mould matched moulds.

Compared to prior art, barb demolding structure of the present utility model, by the first slide block movement driven rotary arm rotation, turning arm rotation is stirred the second slide block and is withdrawed from barb on product, and the fin on product is the male die core moulding, can produce not interfere with fin when the second slide block withdraws from barb, thus moulding the product of fin arranged on the barb exit axis.

[specific embodiment]

See also Fig. 3, Fig. 4 and shown in Figure 5, wherein Fig. 3 has illustrated the schematic perspective view of the utility model barb demolding structure, and Fig. 4 has illustrated the generalized section of the utility model A-A in Fig. 3, and Fig. 5 has illustrated the generalized section of the utility model B-B in Fig. 3.

In the present embodiment, barb demolding structure of the present utility model, be applied in mould, is used for having on moulding barb 11 exit axis the product 30 of fin 12, and take 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 in this angling hole 210 and stirs this first slide block movement 200, also is provided with stopper slot 230 on this first slide block 200;

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

Turning arm 400, it rotatably is located in male die core 100, correspondingly be provided with spatial accommodation in this male die core 100 located therein for this turning arm 400, and these turning arm 400 1 ends extend in described groove 310, also be fixed with projection 410 on this turning arm 400, this projection 410 is stuck in described stopper slot 230.

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