Technical Field
The utility model belongs to the technical field of the injection-moulded technique and specifically relates to a technical field that injection moulding product and mouth of a river separation are related to.
Background
The injection-molded product is a plastic product of various shapes made by using a plastic mold, but the injection-molded product released from the mold usually has a gate into which plastic liquid flows during injection, and the gate is usually located at one end of the injection-molded product. Therefore, after demolding of the injection-molded product, the nozzle is usually removed from the injection-molded product body to obtain the injection-molded product for post-production. In the prior art, manual cutting is usually adopted for removing, so that the labor intensity is high, the production efficiency is low, and the labor cost is high. Subsequently, some injection moulding equipment is equipped with automatic shearing mechanism, removes the mouth of a river through shearing the mechanism, obtains automated production from this, improves production rate, but equipment structure is complicated, and the input is big, and the maintenance cost is high.
Disclosure of Invention
An object of the utility model is to overcome prior art's defect, provide an injection moulding product and mouth of a river autosegregation structure, automatic and mouth of a river separation when realizing the injection moulding product drawing of patterns reduces artifical and cut the process of mechanism re-separation.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
injection moulding product and mouth of a river autosegregation structure, including injection moulding product and the mouth of a river that obtains through the mould shaping, injection moulding product has top and bottom, the mouth of a river is equipped with sneaks into and surpasss the bend portion of injection moulding product's bottom, and the tail end tieback of bend portion connects injection moulding product's bottom, and the direction of tail end tieback is the same with injection moulding product ejection direction of drawing of patterns.
In the above scheme, the tail end of the curve part is conical, and the diameter of the glue position of the tail end connected with the injection molding product is 0.6 mm.
In the above aspect, the shape of the side surface of the curved portion is a C shape, a U shape, or a bracket shape.
The utility model discloses a design bend portion and connect injection moulding product, when satisfying the requirement of moulding plastics, it is ejecting when the product, still can utilize the structural performance of bend portion, give the lagging back pulling force of bend portion, the tail end that reaches bend portion pulls open, with injection moulding product autosegregation to realize drawing of patterns autosegregation mouth of a river, do not need staff and machining, simplify production processes, save the staff, reduction in production cost promotes production efficiency, is favorable to production, has the preferred practicality, accords with the industrial utilization.
Description of the drawings:
fig. 1 is a schematic structural diagram of an embodiment of the present invention;
fig. 2 is a partially enlarged schematic view of the embodiment of fig. 1.
The specific implementation mode is as follows:
the conception, the specific structure and the technical effects of the present invention will be further described with reference to the accompanying drawings, so as to fully understand the objects, the features and the effects of the present invention.
It should be noted that in the description of the present invention, the terms of direction or positional relationship indicated by the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, which are merely for convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
Referring to fig. 1 and 2, it is the preferred embodiment of the present invention shows the drawings, the present invention relates to an injection molding product and nozzle automatic separation structure, including injection molding product 1 and nozzle 2 obtained through the molding of the mold, the specific molding is the current injection molding mode, and is not repeated here. In the figure, the injection molding product 1 is shown as a road cone, the injection molding product 1 is provided with a top part 11 and a bottom part 12, the water gap 2 is provided with a curve part 21 which submerges into and exceeds the bottom part 12 of the injection molding product, the tail end 211 of the curve part 21 is connected back to the bottom part 12 of the injection molding product, and the connection direction of the tail end 211 is the same as the ejection direction of the injection molding product 1. When the curved part 21 meets the requirement of injection molding, when the product is ejected, the structural performance of the curved part can be utilized to provide lagging back tension to the curved part 21, so that the tail end of the curved part is pulled open and is automatically separated from the injection molded product 1, the effect of automatically separating the water gap by demolding is realized, and the water gap 2 is not required to be separated by hands and machining.
Referring to fig. 1 and 2, in the embodiment, in order to improve the automatic separation efficiency, the tail end 211 of the curved portion 21 is designed to be tapered, and the glue position diameter of the tail end 211 connected to the injection molding product is 0.6mm, so that the automatic separation is facilitated while the injection molding and glue injection are ensured. The side shape of the curved part 21 is preferably C-shaped, U-shaped or bracket-shaped, so that the corresponding curvature radius and elasticity are obtained, the tail end of the curved part is pulled open when the product is demoulded, and the effect of automatically separating the water gap during demould is improved.
Referring to fig. 1, in the present embodiment, the nozzle 2 is a symmetric i-shaped structure, and has a main nozzle and a water diversion opening transversely disposed at an end of the main nozzle, and the curved portions 21 are disposed on the water diversion opening and respectively connected to the corresponding injection-molded products 1. This mouth of a river structure realizes a plurality of products of one shot forming, and when ejecting the product, the symmetry I-shaped structure of mouth of a river 2 has good internal stress, also helps giving the lagging back pulling force of bend portion 21, reaches the tail end of bend portion and pulls open, with injection moulding product 1 autosegregation, promotes the efficiency of drawing of patterns autosegregation mouth of a river.
