Abstract
The utility model discloses a die, in particular relates to a die with a high-brightness forming surface that is used for the injection-molding forming of the product with precise surface, which comprises a fixed die, a movable die and a slide block, wherein, the slide block is provided with a projection part; the projection part is provided with a high-brightness forming surface that is used for the forming of the precise surface; the edge of the high-brightness forming surface is provided with a sharp corner. The movable die is provided with an elastic body; when the fixed die, the slide block and the movable die are pushed against each other, the elastic body is compressed against the pressure of the slide block; when the movable die is apart from the fixed die, at least part of the elastic body is recovered the deformation, so that the slide block is separated from the movable die, and the gap between the projection part of the slide block and the movable die become large, and the projection part of the slide part can withdraw in non-contact way corresponding to the product; therefore, the high-brightness forming surface is free from being scratched, and the sharp corner is free from being damaged.
Description
Technical field
The utility model relates to a kind of mould, especially a kind of mould with highlighted forming surface that is applied to have portion's product injection mo(u)lding of precision surface.
Background technology
Be applied to have the mould with slide block of portion's product moulding of precision surface, be faced with a problem: when portion's product are finished the injection moulding operation afterwards with the mould die sinking, when slide block retreats, then highlighted forming surface, the wedge angle of slide block are easy to the product generation friction with portion, and cause the scratch of the highlighted forming surface of slide block, the breakage of wedge angle.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of mould, when making die sinking, can avoid highlighted forming surface, wedge angle impaired on the slide block.
The technical scheme that the utility model adopted is: a kind of mould that is applied to have portion's product injection mo(u)lding of highlighted forming surface, it comprises cover half, dynamic model, is folded in the slide block between described cover half and the dynamic model, described slide block is connected with described cover half by Angle Pin, described slide block has protuberance, have the highlighted forming surface of the precision surface moulding that is used for portion's product on the described protuberance, the edge of described highlighted forming surface also has wedge angle.Described dynamic model is provided with elastomer, and when described cover half, described slide block, when described dynamic model leans successively, described elastomer is in the compressive state of the pressure of the described slide block of opposing; When the described relatively cover half of described dynamic model away from the time, the recovered part deformation and make described slide block and described dynamic model be separated at least of described elastomer, spacing between the protuberance of slide block and the described dynamic model becomes big thus, portion's product are touchless relatively retreats for the protuberance of described slide block, and highlighted forming surface is unlikely to abrade, and it is impaired that wedge angle also is unlikely to.
Described elastomeric material is a rubber.
Also be provided with the position-limit mechanism that is used for when described dynamic model and described slide block are separated, limiting described elastomeric deflection on the described dynamic model.Described position-limit mechanism comprises the unsteady wearing plate that is fixed on the described slide block and offers connecting hole, pass described connecting hole and be used for described unsteady wearing plate is connected screw on the described dynamic model; described unsteady wearing plate can slide along the described relatively dynamic model of described screw; described elastomer is arranged between described unsteady wearing plate and the described dynamic model, and the stroke that the described relatively dynamic model of described unsteady wearing plate slides is 0.2 millimeter.Thus, when the relative cover half of described dynamic model take place away from the time, away from 0.2 millimeter the time, it is maximum that the gap between slide block and the dynamic model reaches, taking-up this moment portion product; When the relative cover half of dynamic model continue away from the time, described position-limit mechanism limits elastomeric deflection and slide block and dynamic model is together spacing, then slide block will be along the relative cover half landing of Angle Pin.
Because the employing of technique scheme in the mould die sinking process, can be avoided the scratch of the highlighted forming surface of slide block, the damage of wedge angle, has protected mould.

The specific embodiment
Below in conjunction with accompanying drawing and concrete embodiment the utility model is described in further detail:
Referring to Fig. 1, a kind of mould that is applied to have portion's product 4 injection mo(u)ldings of precision surface 41, be in injection moulding process, it comprises cover half 1, dynamic model 2, is folded in the slide block 3 between described cover half 1 and the dynamic model 2, described slide block 3 is connected with described cover half 1 by Angle Pin 11, described slide block 3 has protuberance 31, has the highlighted forming surface 32 of precision surface 41 moulding that are used for portion's product 4 on the described protuberance 31, and the edge of described highlighted forming surface 32 also has wedge angle 33.Described dynamic model 2 is provided with elastomer 5, and described cover half 1, described slide block 3, described dynamic model 2 lean successively at this moment, and described elastomer 5 is in the compressive state of the pressure of the described slide block 3 of opposing.
Referring to Fig. 2, when finishing injection moulding, the described relatively cover half 1 of described dynamic model 2 away from the time, the recovered part deformation at least of described elastomer 5, because the restoring force of described elastomer 5, make described slide block 3 be pressed on the surface of described cover half 1, and make described slide block 3 be separated with described dynamic model 2.Form the gap between described thus slide block 3 and the dynamic model 2, described highlighted forming surface 32 is separated with portion's product 4, then can avoid the scratch of highlighted forming surface 32, wedge angle 33 when the mould die sinking.
Specifically, the material of described elastomer 5 is a rubber.
Also be provided with the position-limit mechanism 6 that is used for when described dynamic model 2 is separated with described slide block 3, limiting the deflection of described elastomer 5 on the described dynamic model 2.Described position-limit mechanism 6 comprises the unsteady wearing plate 61 that offers connecting hole 62, pass described connecting hole 62 and be used for described unsteady wearing plate 61 is connected screw 63 on the described dynamic model 2, described unsteady wearing plate 61 can slide along the described relatively dynamic model 2 of described screw 63, and described elastomer 5 is arranged between described unsteady wearing plate 61 and the described dynamic model 2.Preferred 0.2 millimeter of the stroke that the described relatively dynamic model 2 of described unsteady wearing plate 61 slides.This position-limit mechanism 6 makes described dynamic model 2 relative cover half 1 away from 0.2 millimeter distance range the time, described elastomer 5 can be pressed on described slide block 3 described cover half 1 surface, when described dynamic model 2 relative cover half 1 continue away from the time, described slide block 3 retreats described relatively cover half 1 along Angle Pin 11.
