Fig. 1 is mold sections schematic diagram of the present utility model;
Fig. 2 is the close-up schematic view of part A in the utility model Fig. 1;
Fig. 3 is the schematic diagram after the utility model formed product.
Detailed description of the invention
Referring to figs. 1 through Fig. 3, Fig. 1 to Fig. 3 is the structural representation of the utility model specific embodiment, as shown in the figure, a kind of automatic top entry nozzle injection mold with through hole product, comprise die ontology, described die ontology comprises front cavity 1, rear cavity 2, front mould mold insert 3, rear mold mold insert 4, described front mould mold insert 3 is arranged in front cavity 1, a cavity is provided with in described front mould mold insert 3, described rear mold mold insert 4 be arranged in rear cavity 2 and its front end can stretch out forward be inserted into front mould mold insert 3 cavity in, during matched moulds, described front cavity 1, rear cavity 2, front mould mold insert 3, rear mold mold insert 4 encloses formation one product die cavity 5, described rear mold mold insert 4 is for shaped article through hole, runner 11 is provided with in described front cavity 1, described runner 11 port of export and rear mold mold insert 4 front end form a chamber, the false mouth of a river 12 inside product through hole, chamber, the described false mouth of a river 12 is communicated to product die cavity 5 by the inwall of product through hole, and chamber, the false mouth of a river 12 is 0.08mm-0.1mm with the thickness D of product die cavity 5 junction, a thimble 41 corresponding with chamber, the false mouth of a river 12 is provided with in described rear mold mold insert 4.
As preferably, being connected with product through-hole wall of the edge annular in chamber, the described false mouth of a river 12.
As preferably, chamber, the described false mouth of a river 12 is in cone-shaped, and the edge in this chamber, pyramidal false mouth of a river 12 is connected with product through-hole wall, makes the flow velocity of the sol solutions of increase junction, the quality of guarantee formed product.
As preferably, a thimble slide opening is provided with in described rear mold mold insert 4, described thimble 41 is arranged in this thimble slide opening, slip is driven by different drive units as preferred rear cavity 2 and thimble 41, to promote thimble 41, rear cavity 2 respectively, realize point disconnected false mouth of a river 8, other top and an ejecting product 9.
During injection mo(u)lding, sol solutions enters in product die cavity 5 through chamber, the false mouth of a river 12 again, after shaping, a false mouth of a river 8 is formed at the through-hole wall of product 9, and by thimble 41 the false mouth of a river 8 pushed up and break and send, product 9 is released finally by rear mold 2 benevolence, realize automatically being separated of the false mouth of a river 8 and product 9, reduce follow-up water dividing gap operation, be beneficial to the automated production of product, reduce cost of labor and enhance productivity, and be arranged in through hole due to the false mouth of a river, through test of many times, when producing headset plug overcoat series products, when its chamber, false mouth of a river 12 is set to 0.08mm-0.1mm with the thickness D of product die cavity 5 junction, can ensure that sol solutions can enter in product die cavity 5 fast, ensure the quality of formed product, again can after the mouth of a river cuts off, mouth of a river trace is can't see in appearance at product, make product more attractive in appearance.
Embodiment one
False chamber, the mouth of a river 12 is set to 0.08mm with the thickness D of product die cavity 5 junction, and sol solutions can enter in product die cavity 5 fast, zero defect after formed product, and quality is good, and mouth of a river cut-off part can't see mouth of a river trace substantially, cuts off effective.
Embodiment two
False chamber, the mouth of a river 12 is set to 0.1mm with the thickness D of product die cavity 5 junction, and sol solutions can enter in product die cavity 5 fast, zero defect after formed product, and quality is good, and mouth of a river cut-off part can't see mouth of a river trace substantially, cuts off effective.
And when chamber, the false mouth of a river 12 is set to be greater than 0.1mm with the thickness of product die cavity 5 junction, mouth of a river cut-off part can see mouth of a river trace, cut off effect general; When chamber, the false mouth of a river 12 is set to be less than 0.08mm with the thickness of product die cavity 5 junction, mouth of a river cut-off part can't see mouth of a river trace, cut off effective, but the flow velocity of sol solutions is inadequate, very easily cause product defects, yield rate is lower, therefore chamber, the false mouth of a river 12 is set to be greater than 0.1mm or be less than 0.08mm all can not reach required technique effect with the thickness of product die cavity 5 junction.
Above better enforcement of the present utility model is illustrated; certainly; the utility model can also adopt form different from the embodiment described above; the equivalent conversion that those of ordinary skill in the art do under the prerequisite without prejudice to spirit of the present invention or change accordingly, all should belong in protection domain of the present utility model.
