Description

The oblique core pulling exit structure of master mold
【Technical field】
The present invention relates to a kind of mould structure, is specifically related to a kind of oblique core pulling exit structure of master mold.
【Background technology】
When producing plastics product, inclined hole can be provided with product sometimes, the angle for coordinating inclined hole is needed after shaped article Mould is set to exit inclined hole.
Refer to shown in Fig. 1, it depicts a kind of structural representation of the product with inclined hole.On the product 10 have with The inclined hole 11 of the inclined angle of vertical direction.Refer to shown in Fig. 2, Fig. 2 depicts the oblique core pulling of master mold in the prior art and exits knot The schematic diagram of structure.The oblique core pulling exit structure of master mold includes slider body 20, slide core 21, pin 22, briquetting in the prior art 23rd, wear-resistant block 24, driving lever 25 and block 26.After the shaping of product 10, driving lever 25 is stirred slider body 20 and exited, slider body 20 Slide core 21 and pin 22 is driven to exit, so as to exit the inclined hole 11 of product 10.
However, the oblique core pulling exit structure of the master mold of prior art, slide core 21 the appearance of product 10 can leave into Sub-line, area is larger, influences the outward appearance of product 10, is additionally, since that accessory is more, and space-consuming is larger, increases the chi of die holder It is very little, it have impact on mould strength.
In view of this, it is necessary to develop a kind of oblique core pulling exit structure of new master mold in fact, to solve outside above-mentioned influence product The problem of sight and space-consuming are big.
【The content of the invention】
It is therefore an object of the present invention to provide a kind of master mold oblique core pulling exit structure, the oblique core pulling exit structure of the master mold is not The outward appearance of product is not only interfered with, and accessory is less, saves the space of mould.
In order to achieve the above object, the oblique core pulling exit structure of master mold of the invention, has inclined hole for die for molding Product, the oblique core pulling exit structure of master mold include:
Shifting block, its one end are fixed on the upper mounted plate of mould, have inclined first groove on the shifting block;
Briquetting is identical with the angle of inclined hole with inclined inclined-plane, the inclined angle on the inclined-plane thereon;
Contiguous block, on the inclined-plane of the briquetting, described contiguous block one end has a projection for it, and the other end has second recessed Groove, the projection are located in first groove, and the shifting block stirs contiguous block motion;
Pin, its one end have hanging platform, the inclined hole of other end shaped article, and the hanging platform is located in second groove.
Alternatively, the oblique core pulling exit structure of the master mold also includes flexible member, and it is placed on the pin, the elasticity Element one end contradicts the contiguous block, and the other end contradicts the mother module core of the mould.
Alternatively, the flexible member is spring, and flexible member is in the state compressed when mould matched moulds state.
Alternatively, first groove and the second groove are T-slot, correspondingly the T-shaped shape of the projection and pin.
Alternatively, the bottom of the other end of the contiguous block has extended downwardly a fixture block.
Compared to prior art, the oblique core pulling exit structure of master mold of the invention, it is by setting shifting block and contiguous block, in mould After tool die sinking, upper mounted plate, the caster of mould drive shifting block motion, and shifting block stirs contiguous block while moving and is tilted towards retreating Go out, contiguous block exits back the inclined hole for driving pin to exit product.Thus, the oblique pulled core structure of master mold of the invention is not only only inlayed The inclined hole of pin shaped article, the outward appearance of product is not interfered with, and it is simple in construction, accessory is less, saves the space of mould.

【Embodiment】
Referring to shown in Fig. 3 to Fig. 5, wherein Fig. 3 depicts the combination diagram of the oblique core pulling exit structure of master mold of the present invention, Fig. 4 depicts the decomposing schematic representation of the oblique core pulling exit structure of master mold of the present invention, and Fig. 5 depicts the oblique core pulling of master mold of the present invention and exits knot The floor map of structure.
In the present embodiment, the oblique core pulling exit structure of master mold of the invention, there is the production of inclined hole 11 for die for molding Product 10, the mould have upper mounted plate 100, stripper plate 101, caster 102, male template 103, mother module core 104 and male die core 105, the oblique core pulling exit structure of master mold includes:
Shifting block 200, its one end are fixed on the upper mounted plate 100 of mould, recessed with inclined first on the shifting block 200 Groove 201;
Briquetting 300, thereon with inclined inclined-plane 301, the inclined angle on the inclined-plane 301 and the angle phase of inclined hole 11 Together;
Contiguous block 400, on the inclined-plane 301 of the briquetting 300, described one end of contiguous block 400 has projection 401 for it, The other end has the second groove 402, and the projection 401 is located in first groove 201, and the shifting block 200 stirs contiguous block 400 motion, the briquetting 300 play a part of support the contiguous block 400, make inclined-plane 301 of the contiguous block 400 along briquetting 300 to Backed off after random;
Pin 500, its one end have hanging platform 501, the inclined hole 11 of other end shaped article 10, and the hanging platform 501 is located at institute State in the second groove 402.
Wherein, the oblique core pulling exit structure of the master mold also includes flexible member 600, and it is placed on the pin 500, described The one end of flexible member 600 contradicts the contiguous block 400, and the other end contradicts the mother module core 104 of the mould, correspondingly the master mold Provided with correspondingly space so that the flexible member 600 is located therein in benevolence 104, the flexible member 600 when mould molds Auxiliary pin 500 exits back, and plays cushioning effect.
Wherein, the flexible member 600 can be spring, and flexible member 600 is in what is compressed when mould matched moulds state State.
Wherein, the groove 402 of the first groove 201 and second is T-slot, correspondingly the projection 401 and pin 500 T-shaped shape.
Wherein, the bottom of the other end of the contiguous block 400 has extended downwardly a fixture block 403, and the fixture block 403 rises spacing Effect, prevents contiguous block 400 from exiting back excessively.
Refer to shown in Fig. 6, it depicts schematic diagram of the oblique core pulling exit structure of master mold of the present invention in mould.Mould closes After mould, injection molding product 10.Then, mould molds, and upper mounted plate 100, caster 102 drive shifting block 200 to move upwards, dial While block 200 moves upwards, due to the effect of inclined first groove 201 and projection 401, contiguous block 400 is along briquetting 300 Inclined-plane 301 it is tilted backwards exit, contiguous block 400 simultaneously exits with pin 500 is tilted backwards, and pin 500 exits product 10 Inclined hole 11.
Compared to prior art, the oblique pulled core structure of master mold of the invention, not only only pin 500 contact moudling product 10 Inclined hole 11, the outward appearance of product 10 is not interfered with, and it is simple in construction, accessory is less, it is only necessary to shifting block 200, contiguous block 400, briquetting 300 and pin 500, save the space of mould.
