Abstract
The utility model discloses an assembly structure of a submarine gate runner of an injection-molding die, which comprises a molding core of the injection-molding die and a submarine banana-like gate runner arranged on the molding core and used for injecting an injection-molding material, wherein a concave notch is formed below the submarine banana-like gate runner of the molding core, the bottom plane of the concave notch cuts a part of the bottom plane of the submarine banana-like gate runner, the concave notch is communicated with the submarine banana-like gate runner, an embedded part is arranged inside the concave notch, a groove is formed on the upper end surface of the embedded part, and the shape of the groove is the same as that of the cut part of the bottom plane of the submarine banana-like gate runner by the bottom plane of the concave notch. The assembly structure can be used for assembling the submarine banana-like gate runner without needing the half block assembly method. The assembly structure provided by the utility model has the advantages of simple structure and convenience in manufacturing, and prevents the formation of assembly joints on the product during use.
Description
Technical field
The utility model relates to a kind of injection mould sub marine gate runner splicing structure that is applicable to submarine banana shape cast gate runner, belongs to injection mold cast gate runner technical field.
Background technology
At present, the submarine banana shape cast gate runner of existing injection mold, because its shape such as banana shape, for the ease of processing mold, often need the runner of this shape is made the structure of breathing out furan piece formula, and then these are breathed out the assembly units of furan piece rise and be secured on the forming part, the injection mold of the structure fabrication one-tenth of furan piece formula is breathed out in this employing, not only exist complex structure, make the problem of difficulty, and in use, breathe out on the furan piece because the part of product also will be molded over, so will three piece traces occur in the place of breathing out the assembly unit of furan piece, this just is unfavorable for the appearance requirement high product.Therefore, to breathe out the result of use of injection mold of the submarine banana shape cast gate runner of furan block structure still be not ideal enough for existing employing.
Summary of the invention
The purpose of this utility model is: provide a kind of simple in structure, easy to make and can not produce the injection mould sub marine gate runner splicing structure of piece trace in use on product, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: a kind of injection mould sub marine gate runner splicing structure of the present utility model, the core that comprises injection mold, on core, be provided with the cast gate runner of the submarine banana shape that is used to pour into a mould injected plastics material, below the cast gate runner of the submarine banana shape of core, be provided with shrinkage pool, and the bottom surface of the cast gate runner of part submarine banana shape is cut away in the baseplane of shrinkage pool, shrinkage pool communicates with the cast gate runner of submarine banana shape, mold insert is housed in shrinkage pool, on the upper surface of mold insert, be provided with groove, and the shape of groove is identical with the shape of the cast gate runner bottom surface portions of the submarine banana shape that is cut away by the baseplane of shrinkage pool.
The shrinkage pool of above-mentioned core is the step shrinkage pool, and is provided with the boss that matches with this shrinkage pool step on mold insert.
On a side of the shrinkage pool of above-mentioned core, be provided with the guide-localization plane, and on mold insert, be provided with the plane of orientation that matches with the guide-localization plane of this shrinkage pool.
The shrinkage pool center line arrives the distance L 3 of the groove top edge in this mold insert center line left side greater than the mold insert center line to the distance L 1 of the cast gate runner feather edge of the submarine banana shape in this shrinkage pool center line left side; The shrinkage pool center line arrives the distance L 4 of the groove top edge on this mold insert center line right side less than the mold insert center line to the distance L 2 of the cast gate runner feather edge of the submarine banana shape on this shrinkage pool center line right side; And the straight line parallel of distance L 1 and distance L 2 in the straight line parallel of guide-localization plane, distance L 3 and the distance L 4 of shrinkage pool in the plane of orientation of mold insert.
Owing to adopted technique scheme, the utility model does not need to adopt the mode of breathing out the assembly unit of furan piece to get final product the cast gate runner that assembly unit goes out submarine banana shape, because what the utility model adopted is the splicing structure of shrinkage pool and mold insert, therefore greatly reduce difficulty of processing; And the utility model adopts mold insert and the common assembly unit of core to go out the cast gate runner of submarine banana shape, thereby therefore the piece trace that is easy to generate when having eliminated the furan piece assembly unit of traditional Kazakhstan effectively, during use the utility model, can not stay the piece trace on product.So, the utility model compared with prior art, the utility model not only has advantage simple in structure, easy to make, but also has the advantage that can not produce the piece trace in use on product.
