Description

Barb demolding structure

[technical field]

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

[background technology]

The plastic parts of product can use plastic mould to be shaped, for example, the plastic parts such as the shell of electronic product. Due to popularizing of electronic product, the improvement for plastic mould also becomes widely studied problem.

When producing plastic cement products, referring to shown in Fig. 1, on the product 10 of Fig. 1, existing barb 11, has again Fin 12, and the exit axis of barb 11 is inconsistent with the exit axis of fin 12.Refer to shown in Fig. 2, The barb demolding structure of prior art generally uses taper pin 20 to exit this barb 11, and taper pin 20 is on the top of mould Barb 11 is exited in lateral movement under ejecting plate active force, but, this fin 12 can produce interference with taper pin 20, Taper pin 20 is made to exit, it is necessary to change this fin 12, if client disagrees this fin 12 of modification, then Mould cannot die sinking, it is impossible to have the product 10 of fin 12 on shaping barb 11 exit axis.

In view of this, it is necessary in fact to develop a kind of barb demolding structure, move back to solve the above-mentioned barb that cannot be molded The problem having the product of fin on outgoing direction.

[content of the invention]

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

In order to achieve the above object, the barb demolding structure of the present invention, is applied in mould, and shaping barb moves back Having the product of fin on outgoing direction, with mould die sinking direction as vertical direction, this barb demolding structure includes:

Male die core, the fin on its shaped article；

First slide block, which is provided with the angling hole of the inclined angle with vertical direction, is provided with tiltedly in this angling hole This first slide block movement stirred by guide pillar, and this first slide block is provided with stopper slot；

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

Turning arm, it is movable is located in male die core, and this turning arm one end extend in described groove, should Being further fixed on projection on turning arm, this projection is stuck in described stopper slot.

Alternatively, described turning arm is L-shaped, is provided with rotary shaft in this turning arm, correspondingly this turning arm around This rotary shaft is moved.

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

Alternatively, described first slide block is provided with step surface, and when mould matched moulds, this step surface fits in described Turning arm.

Compared to prior art, the barb demolding structure of the present invention, arm is rotated by the first slide block movement Rotating, turning arm rotary dial the second slide block exits the barb on product, and the fin on product is male die core Shaping, will not produce with fin when the second slide block exits barb and interfere, thus be molded on barb exit axis There is the product of fin.

[detailed description of the invention]

Referring to shown in Fig. 3, Fig. 4 and Fig. 5, wherein Fig. 3 depicts the solid of barb demolding structure of the present invention Schematic diagram, Fig. 4 depicts the generalized section of present invention A-A in Fig. 3, Fig. 5 depict the present invention in The generalized section of B-B in Fig. 3.

In the present embodiment, the barb demolding structure of the present invention, it is applied in mould, be used for being molded barb 11 There is the product 30 of fin 12 on exit axis, with mould die sinking direction as vertical direction, this barb demolding structure Including:

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

First slide block 200, which is provided with the angling hole 210 of the inclined angle with vertical direction, this angling hole 210 In be provided with Angle Pin 220 and stir this first slide block movement 200, this first slide block 200 is additionally provided with stopper slot 230；

Second slide block 300, it is located at the barb 11 in male die core 100 on shaped article 10, correspondingly this public affairs Die 100 is provided with receiving space be located therein for this second slide block 300, this second slide block 300 sets Fluted 310；

Turning arm 400, it is rotatably disposed within male die core 100, is correspondingly provided with appearance in this male die core 100 Receiving space is located therein for this turning arm 400, and this turning arm 400 one end extend into described groove 310 In, this turning arm 400 is further fixed on projection 410, this projection 410 is stuck in described stopper slot 230.

Wherein, described turning arm 400 is L-shaped, is provided with rotary shaft 420, correspondingly should in this turning arm 400 Turning arm 400 moves around this rotary shaft 420.

Wherein, described projection 410 is cylinder, for making this cylinder be integrally formed with this turning arm 400, and this circle Post one end is stuck in described stopper slot 230, and the other end extend in turning arm 400.

Wherein, described first slide block 200 is provided with step surface 240, and when mould matched moulds, this step surface 240 pastes Together in described turning arm 400, when mould matched moulds, this step surface 240 assists described turning arm 400 return.

Please refer to shown in Fig. 6, Fig. 7 and Fig. 8, wherein Fig. 6 depict barb demolding structure of the present invention in The schematic perspective view of die opening state, Fig. 7 depicts the generalized section of present invention C-C in Fig. 6, Fig. 8 Depict the generalized section of present invention D-D in Fig. 6.

After mould die sinking, male die core 100 is away from the mother module core of mould thus exits the fin 12 on product 10, Simultaneously described Angle Pin 220 stirs described first slide block 200 (direction shown in arrow) to the left motion, when the After one slide block 200 moves to projection 410 and stopper slot 230 conflict to the left, projection 410 is at stopper slot 230 Active force under arm 400 be rotated rotate, turning arm 400 around described rotary shaft 420 rotate counterclockwise from And stir the second slide block 300 (arrow rightabout) to the right motion, make the second slide block 300 exit product 10 On barb 11.

When mould matched moulds, Angle Pin 220 is stirred the first slide block 200 and is moved right, the first slide block 200 Step surface 240 promotes turning arm 400 return, and turning arm 400 drives the second slide block 300 return.

The barb demolding structure of the present invention, is rotated arm 400 by the first slide block 200 motion and rotates, rotation Pivoted arm 400 rotary dial the second slide block 300 exits the barb 11 on product 10, and the fin on product 10 12 are molded for male die core 100, and the second slide block 300 exits to produce with fin 12 interferes, thus is molded There is the product 10 of fin 12 on barb 11 exit axis.
