[detailed description of the invention]
Incorporated by reference to consulting Fig. 1, Fig. 2, Fig. 1 illustrates as a kind of structural representation of product, Fig. 2 illustrate the matched moulds status architecture schematic diagram of Enforced stripping structure one preferred embodiment into mould of the present invention.
In order to achieve the above object, the Enforced stripping structure of mould provided by the invention, this mould molding end has the product 10 of several annular arrangement barbs 11, respectively there is gap between this barb 11, described barb 11 can be in the claw shape bent inwards, this mould has upper mounted plate 100, caster 101, mother module core 102, male die core 103, the male template 104 sequentially set up, mother module core 102 is located in described caster 101, described male die core 103 is located in described male template 104, and this demolding structure comprises:
Slide block 105, be located between described mother module core 102 and described male die core 103, described slide block 105 has the structure of the outer wall of the main body of shaping described product 10, and slide block 105 can be symmetrical two of setting up herein;
Lower link bar 106, fixed plate 100 is fixed in its one end, and the other end has boss, and described boss is movable to be located in a containing groove 107 of described caster 101, and described containing groove 107 one end has hanging platform, and described hanging platform and described boss cooperatively interact;
Shutter 108, described caster 101 is fixed in its one end, and the other end is fixed on described male template 104;
First enters son 109, fixed plate 100 is fixed in its one end, the other end has the structure in shaping each outer wall of described barb 11 and the gap of barb 11, described first enters in son 109 to have the first through hole 110 and the second through hole 111 be interconnected, and the internal diameter of described first through hole 110 is less than the internal diameter of described second through hole 111;
Second enters son, it has interconnective first connecting portion 112 and the second connecting portion 113, described first connecting portion 112, second connecting portion 113 respectively correspondence to be located in described first through hole 110, second through hole 111 and size corresponding matching, also be the internal diameter that external diameter is equal to or slightly less than the internal diameter of described first through hole 110, the external diameter of described second connecting portion 113 is equal to or slightly less than described second through hole 111 of described first connecting portion 112, one end of described first connecting portion 112 has the structure of the inwall of shaping each described barb 11.
Wherein, the operating range of described second connecting portion 113 in described second through hole 111 is greater than the height of described barb 11, thus make described first to enter son 109 after the described product 10 of disengaging, and between product 10, there is enough distances, guarantee described second enter son have enough come to nothing by force between; The operating range of described lower link bar 106 in described containing groove 107 is greater than the operating range of described second connecting portion 113 in described second through hole 111 and the height sum of described barb 11, thus guarantees that described product 10 is carried out second time die sinking again by after completely strong taking off.
Please combine again and consult Fig. 3, Fig. 4, the first time die sinking second stage status architecture schematic diagram that Fig. 3 illustrates die sinking first time, the status architecture first stage schematic diagram of Enforced stripping structure one preferred embodiment for mould of the present invention, Fig. 4 illustrates Enforced stripping structure one preferred embodiment into mould of the present invention.
As shown in the figure, first time die sinking is between fixed plate 100 and described caster 101, described first enters son 109 departs from described product 10 gradually, after the described second described second connecting portion 113 entering son contacts with described second through hole 111, described first enters son 109 drives described second to enter son to force to depart from the barb 11 of described product 10, until described second enters son and depart from completely with described product 10.
Visible, adopt above-mentioned Enforced stripping structure can reach several annular arrangement barbs 11 and being separated between mould of product 10 end.
Please combine again and consult Fig. 5, Fig. 5 illustrates the second time die opening state structural representation of Enforced stripping structure one preferred embodiment into mould of the present invention.
After the boss of described lower link bar 106 contacts with the hanging platform of described containing groove 107, described shutter 108 is pulled open gradually, carries out second time die sinking between described caster 101 and described male template 104, and described slide block 105 departs from the outer wall of described product 10.
Wherein, described product 10 can also have endoporus, and described demolding structure also comprises sleeve 114, and its one end has the structure of the endoporus of shaping described product 10, and from the above, after carrying out second time die sinking, described sleeve 114 ejects described product 10.
In addition, described demolding structure can also comprise spring 115, and described spring 115 one end is held in fixed plate 100, and the other end is held in described second connecting portion 113, thus the precompression of spring 115 is relied on when first time die sinking, described second can be avoided to enter son and to leave product 10; Described second connecting portion 113 correspondingly can have stopper slot, and described spring 115 is located in described stopper slot, thus reaches the position-limiting action to spring 115, and spring stress is stablized.
In addition, described demolding structure also comprises shifting block 116, and described caster 101 is fixed in its one end, and the other end is inserted in the skewed slot of described slide block 105, during second time die sinking, is driven the motion of described slide block 105 by described shifting block 116.
It is noted that the invention is not restricted to above-mentioned embodiment, any simple modification that any those skilled in the art do above-described embodiment based on technical solution of the present invention, equivalent variations and modification, all fall within the scope of protection of the present invention.
