Abstract
The utility model provides a cooling water channel for molds of cup-shaped products. A rear mold insert can be deeply and uniformly cooled and does not deform, so that the service life of the mold is prolonged, and the injection molding cost is reduced. The cooling water channel comprises a front mold, a rear mold, a front mold insert and a rear mold insert, wherein a cavity is defined by the front mold, the rear mold, the front mold insert and the rear mold insert; a product is arranged in the cavity. The cooling water channel is characterized in that a central cylindrical cavity is formed in the center of the rear mold insert; the rear mold is supported on a plate B; a water inlet cavity is formed in the plate B; the water inlet cavity comprises a horizontal end and a vertical end; the bottom of the vertical end is communicated with the inner side of the horizontal end; a longitudinal separator is arranged in the central cylindrical cavity; the central cylindrical cavity is separated into two cavities, comprising a cooling water ascending cavity in one side and a cooling water descending cavity in the other side, through the longitudinal separator.
Description
Technical field
The utility model relates to the technical field of structures of product mold, is specially the cooling water channel of the mould of cup-shaped based article.
Background technology
The cooling water channel of the mould of darker cup-shaped based article, there is the shortcoming that cannot reach depths in it, make the injection temperature of rear mold mold insert higher in cooling procedure, easily causes for a long time the distortion of rear mold mold insert, and then make the working life of mould short, increase injection moulding cost.
Summary of the invention
The utility model provides the cooling water channel of the mould of cup-shaped based article, and it makes the cooling of rear mold mold insert can reach depths and cooling even, guarantees that rear mold mold insert is indeformable, and then makes the long working life of mould, has reduced injection moulding cost.
The cooling water channel of the mould of cup-shaped based article, its technical scheme is such: it comprises front mould, rear mold, front mould mold insert, rear mold mold insert, described front mould, rear mold, front mould mold insert, rear mold mold insert surrounds die cavity, in described die cavity, be goods, it is characterized in that: the center of described rear mold mold insert has centered cylinder cavity, described rear mold is supported on B plate, in described B plate, have intake antrum, described intake antrum comprises horizontal ends, vertically end, the bottom of described vertical end is communicated with the inner side of described horizontal ends, in described centered cylinder cavity, be provided with longitudinal baffle, centered cylinder cavity is divided into two cavitys by described longitudinal baffle, comprise a side cooling water rising chamber, opposite side cooling water decline chamber, the upper end in the upper end in the cooling water rising chamber in described centered cylinder cavity and described cooling water decline chamber interconnects, the top of described vertical end is communicated with the lower inlet in described cooling water rising chamber, the bottom in described cooling water decline chamber is positioned at described rear mold place and is provided with outlet, described outlet is communicated with water chamber, the bottom supporting of described rear mold mold insert is in described B plate, between the anchor ring in the outside of the rear mold mold insert of described centered cylinder cavity and described B plate, sealing ring is installed.
It is further characterized in that: sprue bush is positioned at the center mounting groove of described front mould mold insert, and described runner is positioned at the center of described sprue bush, and described runner is communicated with described die cavity.
Adopt after structure of the present utility model, cooling water enters cooling water rising chamber from the horizontal ends of B plate one side intake antrum passes into vertical end, because centered cylinder cavity is divided into two cavitys by longitudinal baffle, comprise a side cooling water rising chamber, opposite side cooling water decline chamber, describedly state the upper end in the cooling water rising chamber in centered cylinder cavity and the upper end in described cooling water decline chamber interconnects, cooling water just can lead to the top of centered cylinder cavity, enter again cooling water decline chamber from top, get back to afterwards the bottom of rear mold mold insert, flow into water chamber from the outlet of bottom, like this, just form a cooling loop, and between the anchor ring in the outside of the rear mold mold insert of described centered cylinder cavity and described B plate, sealing ring is installed, anti-sealing overflows between the gap between rear mold mold insert and B plate, it makes the cooling of rear mold mold insert can reach depths, and cooling even, guarantee that rear mold mold insert is indeformable, and then make the long working life of mould, reduce injection moulding cost.
