Abstract
The utility model discloses a gas-assisted injection molding die for an automobile handrail. The gas-assisted injection molding die comprises a die body, a die cavity (2) formed in the die body and a flow channel (1) formed in the die body, wherein a sprue (3) is formed on the side wall of the die cavity (2); the die cavity (2) is communicated with the flow channel (1) through the sprue (3); the sprue (3) is formed on the corner of the upper side wall (2.1) at one end of the die cavity (2); and a check block (4) is arranged in end of the die cavity (2) and close to an inner end surface at the end of the die cavity (2). By the gas-assisted injection molding die, the position of a weld mark can be transferred to the side of a product.
Description
Technical field
The utility model relates to mould applications, relates to or rather a kind of injection moulding gas-assisted forming mold for automobile armrest.
Background technology
Automobile armrest adopts the injection moulding assisted injection molding techniques, and this technique is that the gas injection is entered in melt, for the manufacture of the hollow space of moulding article.The advantage of this kind technique be without shrink mark, lightweight, save material, shorten molding cycle.See also shown in Figure 1ly, the injection moulding gas-assisted forming mold that is used for automobile armrest of prior art comprises die ontology, be located at the die cavity in die ontology and be located at runner in die ontology.The sidewall of described die cavity is provided with cast gate, and described die cavity is connected with described runner by cast gate.The mould of prior art, described material road junction are located on the middle part of end face of described die cavity.Because the medium position of the end of injection-molded item is provided with installing hole, therefore in the process of injection moulding, the medium position of the end of die cavity is provided with core rod, and the medium position of the end face of die cavity is located at the material road junction, so in advancing the process of glue, easily form a weld mark in the positive centre position of injection-molded item, affect widely the visual effect of goods.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of and the position transfer of weld mark can be arrived the injection moulding gas-assisted forming mold that is used for automobile armrest of the side of goods.
Technical solution of the present utility model is, a kind of injection moulding gas-assisted forming mold that is used for automobile armrest with following structure is provided, and comprises die ontology, is located at the die cavity in described die ontology and is located at runner in described die ontology; The sidewall of described die cavity is provided with cast gate, and described die cavity is connected with described runner by cast gate; It is characterized in that: described cast gate is located on the corner of upper side wall of an end of described die cavity; Be provided with block in described die cavity, described block is located in an end of described die cavity and near the inner face of an end of described die cavity.
After adopting above structure, the injection moulding gas-assisted forming mold for automobile armrest of the present utility model compared with prior art, has the following advantages:
be located at the corner of upper side wall of an end of described die cavity due to the cast gate of the injection moulding gas-assisted forming mold for automobile armrest of the present utility model, be provided with block in described die cavity, described block is located in an end of described die cavity and near the inner face of an end of described die cavity, like this, in the process of injection moulding, glue enters in die cavity by runner and cast gate, be subjected to the effect of block, two-way glue is converged at the sidepiece of die cavity, therefore the weld mark of the goods of injection mo(u)lding has also just appeared at the side of goods, the surface of weld mark is smooth, therefore, can reduce the impact of goods on visual effect.
As a kind of improvement of the present utility model, described cast gate is the submarine spot pouring mouth.After adopting this kind structure, after injection mo(u)lding, the surface can not stay obvious vestige, can not affect the outward appearance of goods.
Description of drawings
Fig. 1 is the structural representation that advances the glue mode of the injection moulding gas-assisted forming mold that is used for automobile armrest of prior art.
Fig. 2 is the structural representation that advances the glue mode of the injection moulding gas-assisted forming mold for automobile armrest of the present utility model.
Shown in figure: 1, runner, 2, die cavity, 2.1, upper side wall, 3, cast gate, 4, block.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
See also shown in Figure 2ly, the injection moulding gas-assisted forming mold for automobile armrest of the present utility model comprises die ontology, is located at the die cavity 2 in die ontology and is located at runner 1 in described die ontology.The sidewall of described die cavity 2 is provided with cast gate 3, and described die cavity is connected with described runner 1 by cast gate 3.Described cast gate 3 is located on the corner of upper side wall 2.1 of an end of described die cavity 2.Be provided with block 4 in described die cavity 2, described block 4 be located in an end of described die cavity 2 and the inner face near an end of described die cavity 2 in.In this specific embodiment, described cast gate 3 is the submarine spot pouring mouth, and so-called spot pouring mouth refers to that cast gate is that the aperture of circular through hole and this cast gate is less, and the mode that the submarine spot pouring mouth adopts the submarine point to advance glue is advanced glue.
Claims (2)
1. an injection moulding gas-assisted forming mold that is used for automobile armrest, comprise die ontology, be located at the die cavity (2) in described die ontology and be located at the interior runner (1) of described die ontology; The sidewall of described die cavity (2) is provided with cast gate (3), and described die cavity (2) is connected with described runner (1) by cast gate (3); It is characterized in that: described cast gate (3) is located on the corner of upper side wall (2.1) of an end of described die cavity (2); Be provided with block (4) in described die cavity (2), described block (4) is located in an end of described die cavity (2) and near the inner face of an end of described die cavity (2).
