For above-mentioned and other purpose of the present utility model, feature, advantage and embodiment can be become apparent, being described in detail as follows of appended accompanying drawing:
Figure 1 shows that existing ox horn advances the schematic diagram of rubber moulding tool.
Figure 2 shows that the ox horn according to the utility model one embodiment advances the schematic diagram of rubber moulding tool.
The specific embodiment
Below will and describe clear explaination spirit of the present utility model in detail with accompanying drawing, any those of ordinary skill in the art is after understanding preferred embodiment of the present utility model, when can be by the disclosed technology of the utility model, change and modification, and do not break away from spirit of the present utility model and scope.
With reference to Fig. 1, it is depicted as the schematic diagram that existing ox horn advances the rubber moulding tool.As shown in fig. 1, ox horn advances the smooth curve shape cone that has a shape such as ox horn formula in the rubber moulding tool 100, it promptly is ox horn type runner 102, it has first opening 104 and second opening 106, dwindle gradually from the sectional dimension of first opening, 104 to second openings 106, therefore the sectional dimension of first opening 104 is greater than the sectional dimension of second opening 106.Second opening 106 connects the die cavity 108 of mold formed product, and the shape of die cavity 108 is parts of a turnover, and second opening 106 and die cavity 108 junctions are on folding line, and its contact point is exactly a cast gate.
The plastic that is in molten condition injects ox horn from first opening and advances rubber moulding tool 100, and the cast gate that is connected with die cavity 108 from second opening 104 enters die cavity 108, forms the shape of product in die cavity 108.After formed product, ox horn need be advanced rubber moulding tool 100 and die cavity 108 just product fracture breaks away from the cast gate place, eject design owing to use, ox horn advances rubber moulding tool 100 relative die cavities 108 and down moves, the then relative ox horn of die cavity 108 advances rubber moulding tool 100 toward the top motion, this is subjected to downward involving of power and whole sinking with regard to causing the plastic at second opening, 106 places, thereby draw recessed in the formation of the surface of product, just the flat surface place of product can form a tangible depression, and this depression is just dashed material shadow 110.
Please refer to Fig. 2 this moment, and it is depicted as the schematic diagram that advances the rubber moulding tool according to the ox horn of the utility model one embodiment.Ox horn advances the smooth curve shape cone that has a shape such as ox horn formula in the rubber moulding tool 100, it promptly is ox horn type runner 102, it has first opening 104 and second opening 106, dwindle gradually from the sectional dimension of first opening, 104 to second openings 106, therefore the sectional dimension of first opening 104 is greater than the sectional dimension of second opening 106.Unlike the prior art be also to be provided with a chamber 200, the second openings 104 at second opening, 106 places and directly not to be connected, but connect second opening 104 and die cavities 108 by chamber 200 with die cavity 108.Chamber 200 is cavitys of right angle trigonometry body in the present embodiment, because the shape of product of 108 moulding of die cavity has right angle bending, two right-angle sides of right angle trigonometry body can be complementary with the right angle bending.The tangent plane of chamber 200 and second opening, 104 junctions is that first tangent plane, 202, the first tangent planes 202 are an angle with the product stripping direction shown in the arrow, and this angle is the acute angle of 3 degree.Angle only is the usefulness of signal among the figure, is not to draw according to actual size.
