Background technology

Under industrial environment now, the application of mould is quite general, and and is widely applied among various sophisticated products.Yet sophisticated product, because its structure is more complicated, to the more high characteristic of finished product permissible accuracy, makes its corresponding mould structure more complicated.

During general die sinking, the Angle Pins of how can arranging in pairs or groups between male die core, slide block, mother module core, and utilize and provide the active force perpendicular to die sinking direction to Angle Pin, moving slider, departs from male die core and mother module core mutually.Yet this kind of mode really exists problem, when the demoulding, slide block is under Angle Pin traction or under external force collision, may there is slightly mobile situation, cause the damage (wherein, more serious with male die core and the mother module core situation of the demoulding vertically) that cannot expect.

And existing solution nothing more than: for fear of the micro-movement that cannot expect, take to increase the internal diameter of the pilot hole of slide block more, make Angle Pin and slide block have cushion space (in other words, it is poor if having time that Angle Pin starts to move to promotion slide block), to avoid slide block to move unexpectedly.Or the positioning bead buckle slide block of can arranging in pairs or groups, to guarantee that slide block can arbitrarily not move.

But above-mentioned two kinds of solutions all have its defect, the former adopts the mode that cushion space is set, and cannot control accurately demoulding situation, and user needs how many displacements can make slide block move uncertain Angle Pin; The latter's positioning bead exists that positioning bead contained spring not necessarily can rebound really, buckle slide block or the contained spring problem such as come off really, and the micro-mobile problem that makes to expect there is no method and really solves.

The specific embodiment

Hereinafter with reference to relevant drawings, the mould according to preferred embodiment of the present invention is described, wherein identical element is illustrated the reference marks with identical, and omission is not illustrated with the non-directly related element of the present invention for the ease of understanding.

Please also refer to Fig. 1 to Fig. 3, be sequentially respectively the schematic diagram in not yet die sinking of mould 1 of the present invention, the first die sinking stage and the second die sinking stage.

Please first consult Fig. 1, for the mould 1 of two-period form die sinking of the present invention is in not yet die sinking (closure) state, and mould 1 is arranged at a substrate 2.Mould 1 of the present invention comprises male die core 11, mother module core 12, slide block 13, inclined guide 14 and shutter 15.Wherein, mother module core 12 can arrange with male die core 11 collocation, and mother module core 12 can arrange in pairs or groups male die core 11 matched moulds or the demoulding, in other words, at mould 1 not yet during the demoulding, male die core 11, mother module core 12 and slide block 13 setting adjacent one another are.

Slide block 13 is arranged between male die core 11 and mother module core 12, and slide block 13 is provided with pilot hole 132 and pinching hole 134.One end of inclined guide 14 couples mother module core 12, and the other end is arranged at pilot hole 132.In addition, the present invention also can comprise that the pilot hole 132 of an enforcement aspect is the oblique slide block 13 that runs through.

Wherein, the outward appearance of the better collocation inclined guide 14 in the shape of pilot hole 132 and angle of inclination, for example, the inclined guide 14 of the present embodiment is cylinder, pilot hole 132 is cylindrical bore.

In the state of Fig. 1, inclined guide 14 is arranged at (part submerge in) pilot hole 132.And the inclined guide 14 diameter L1 of the present embodiment are approximately 20 millimeters, pilot hole 132 internal diameter L2 more can be slightly larger than approximately 4 millimeters of inclined guide 14 diameter L1.In addition, one end of shutter 15 is coupled to male die core 11, and the other end of shutter 15 is arranged at pinching hole 134.The external diameter of the other end of shutter 15 is slightly larger than the diameter in pinching hole 134, makes shutter 15 mounting boards in pinching hole 134, therefore sustainable existence frictional force between shutter 15 and pinching hole 134.

Wherein, shutter 15 can be resin shutter, and utilizes fixture (figure does not indicate) to make its one end couple, be fixed on male die core 11, and the material that shutter 15 other ends are arranged at pinching hole 134 is resin material.In brief, when slide block 13 goes to the first die sinking during the stage in die opening state not yet, utilize shutter 15 and pinching hole 134 to be still on substrate 2, relative to male die core 11, do not move.

Mould 1 of the present invention also can comprise a position-limiting unit 16, the mobile route that it is arranged at substrate 2 and is positioned at slide block 13, and its object stops after being to make slide block 13 to move to required distance.And slide block 13 of the present invention also can comprise buckle slot 136, and buckle slot 136 can cooperatively interact with position-limiting unit 16, to control the movement of slide block 13.

The position-limiting unit 16 of the present embodiment comprises positioning piece 161, and keeper 161 is arranged at the locating slot 1612 of substrate 2, and keeper 161 can with buckle slot 136 buckles of slide block 13.The position-limiting unit 16 of the present embodiment also comprises a block piece 162, though graphic illustration keeper 161 is positioning bead, also can have the keeper of enforcement aspect is positioning key, neither with the present embodiment, is limited.

Need supplementary notes, the position-limiting unit 16 of Fig. 1 not with shutter 15 cross section altogether, Fig. 1, only for convenience of signal, is drawn on same cross section by position-limiting unit 16 and shutter 15, but during actual disposition, should be as limit.

Please especially with reference to Fig. 2, in the first die sinking stage, one external force is provided, inclined guide 14 is moved up along pilot hole 132, and (now inclined guide 14 leaves the inner surface of pilot hole 132, in other words, in this first die sinking stage, start and the time that finishes moment, inclined guide 14 does not contact with the inner surface of pilot hole 132), and provided this mother module core 12 1 thrusts, make male die core 11 separated with mother module core 12 (now slide block 13 does not move), until the inner surface rear of inclined guide 14 1 side laminating pilot holes 132 stops mobile.

What need special instruction is, in this stage, when inclined guide 14 moves, slide block 13 is still on substrate 2 by sustainable existence frictional force between shutter 15 and pinching hole 134, therefore when the external force providing in the first die sinking stage is less than aforementioned frictional force, slide block 13 will not have any displacement.

Then, please refer to Fig. 3, in the second die sinking stage, provide another external force (need at least be greater than the frictional force in 134, shutter 15 and pinching hole), make inclined guide 14 continue to move along pilot hole 132, and provide slide block 13 1 thrusts.

When aforementioned thrust overcomes after the frictional force in 134, shutter 15 and pinching hole, slide block 13 starts mobile, and slide block 13 is moved relative to male die core 11.In other words, now inclined guide 14 provides slide block 13 thrust left, makes slide block 13 start to be moved to the left, until when slide block 13 contact block pieces 162 and keeper 161 are snapped in buckle slot 136, slide block 13 sides stop mobile.Now, male die core 11 is separated with slide block 13.

In sum, mould of the present invention during the stage, is only pulled away from male die core by mother module core in the first die sinking, and do not move/promote slide block, when mother module core leaves after a distance, inclined guide moves and promotes slide block along pilot hole, makes slide block separated with male die core (the second die sinking stage).In addition, more utilize the frictional force in the pinching hole of shutter and slide block, and during the stage, provide slide block of short duration inactive state in the first die sinking.Therefore utilize above-mentioned configuration, the problem of micro-movement when slide block does not move when the present invention can be achieved in die sinking moment slide block and do not move, accurately locate and solve die sinking.

The foregoing is only illustrative, but not be restricted person.Anyly do not depart from spirit of the present invention and scope, and the equivalent modifications that it is carried out or change all should be contained in claims.
