Abstract
The invention discloses a white material mold insert, which comprises a mold insert body and a fluid flow passage; the fluid flow passage is arranged in the mold insert body and is of an L shape; an outlet of the fluid flow passage is communicated with a branch flow passage on a splitter plate when the mold insert is installed in the splitter plate; an inner corner of the fluid flow passage is configured as a right angle; an outer corner of the fluid flow passage adopts a bevel edge; and the maximum width of the corner of the fluid flow passage is equal to the width of the straight-line segment of the fluid flow passage. According to the invention, the maximum width of the corner of the fluid flow passage is equal to the width of the straight-line segment of the fluid flow passage, in this way no residual plastic solution exists in the fluid flow passage during the injection molding, so that flaws such as black points and the like produced in the secondary injection molding by the white material mold insert can be avoided; and the white material mold insert provided by the invention is simple in structure and is practical.
Description
Technical field
The present invention relates to a kind of white material mold insert, especially relate to the white material mold insert of using in a kind of injection mold that is used for injection moulding white or opaque products especially, belong to injection mold component technology field.
Background technology
Injection mold is often used in the modern industrial, is commonly used to the plastic solution of liquid state is injected in the injection mold cavity; Common mold insert shown in accompanying drawing 1, comprises insert body 2, fluid passage 4; 4 L-shaped insert body 2 inside that are arranged on, said fluid passage; In the time of in mold insert is installed in flow distribution plate 1, the outlet of said fluid passage 4 is communicated with split channel 3 on the flow distribution plate 1; The setting that meets at right angles of the interior turning 5 of said fluid passage 4; The outer turning 6 of said fluid passage 4 roughly is the fillet design; Fluid passage 4 Breadth Maximum around the corner of this structure is wideer than the width of the fluid passage 4 at non-turning, thereby when the cast plastic solution, 4 outer corner forms the plastic solution deposition in the fluid passage easily.When re-using this injection mold for the second time, the plastics of deposition can form stain and take out of with plastic solution, on product, form flaws such as stain, cause substandard products.
Summary of the invention
The present invention seeks to provide the white material mold insert of using in a kind of injection mold that is used for injection moulding white or opaque products especially for the deficiency that overcomes prior art.
For achieving the above object, the technical scheme that the present invention adopts is: a kind of white material mold insert comprises insert body, fluid passage; The L-shaped insert body inside that is arranged on, said fluid passage; In the time of in mold insert is installed in flow distribution plate, the outlet of said fluid passage is communicated with split channel on the flow distribution plate; The setting that meets at right angles of the interior turning of said fluid passage; The hypotenuse chamfering is adopted at the outer turning of said fluid passage.
Preferably, the Breadth Maximum of said fluid passage corner is identical with the straightway width of fluid passage.
Beneficial effect of the present invention is mainly reflected in: the Breadth Maximum of fluid passage corner is identical with the straightway width of fluid passage described in the white material mold insert of the present invention; Plastic solution can residual plastic solution in the fluid passage in injection moulding process like this, thereby can avoid said white material mold insert when second time injection moulding, to produce flaws such as stain; The present invention is simple in structure, practical.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Accompanying drawing 1 is the working state schematic representation of the mold insert of prior art;
The working state schematic representation of accompanying drawing 2 white material mold inserts of the present invention;
Wherein: 1, flow distribution plate; 2, insert body; 3, split channel; 4, fluid passage; 5, interior turning; 6, outer turning; 11, flow distribution plate; 12, insert body; 13, split channel; 14, fluid passage; 15, interior turning; 16, outer turning.
The specific embodiment
Of the present invention a kind of white material mold insert shown in accompanying drawing 2 comprises insert body 12, fluid passage 14; 14 L-shaped insert body 12 inside that are arranged on, said fluid passage; In the time of in mold insert is installed in flow distribution plate 11, the outlet of said fluid passage 14 is communicated with split channel 13 on the flow distribution plate 11; The setting that meets at right angles of the interior turning 15 of said fluid passage 14; The hypotenuse chamferings are adopted at the outer turning 16 of said fluid passage 14, and the Breadth Maximum of said fluid passage 14 corners is identical with the straightway width of fluid passage 14.
Beneficial effect of the present invention is mainly reflected in: the Breadth Maximum of fluid passage corner is identical with the straightway width of fluid passage described in the white material mold insert of the present invention; Plastic solution can residual plastic solution in the fluid passage in injection moulding process like this, thereby can avoid said white material mold insert when second time injection moulding, to produce flaws such as stain; The present invention is simple in structure, practical.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
Claims (2)
