Abstract

The utility model relates to an improvement of a crystal plastic floor extrusion mould, in particular to an integral mold core and spreader extrusion mould. The extrusion mould is provided with a mould body, flow channels are arranged in the mould body, a support plate, a confluence plate, a template C, a template B and a template A are mounted above the mould body through screws respectively, the template C, the template B and the template A are provided with mold cavities, the support plate and the flow plate are provided with the runners, and mold cores are mounted in the mold cavities of the template C, the template B and the template A and in the runners of the support plate, the confluence plate and the mold body. Particularly, the mold cores are provided with swallowtail wings and spreaders respectively, the confluence plate is provided with swallowtail grooves, and the mold cores are mounted through the swallowtail grooves on the swallowtail wings and the confluence plate in an inlaid manner. The extrusion mould solves the problems that mold cores easily swing in mold cavities of an existing crystal plastic floor extrusion mould, confluence effect of extrusion material in the mold cavities is poor, and manufacturing cost of the mould is high. The extrusion mould is mainly the improvement of the existing crystal plastic floor extrusion mould.

Description

Unitary core is divided the flow cone extrusion die

The (1) technical field: the utility model relates to the improvement of rock quartz plastic floor extrusion die, is that a kind of unitary core is divided the flow cone extrusion die.

The (2) background technology: core in the prior art rock quartz plastic floor extrusion die and branch flow cone are to be embedded in respectively on the different templates, and core is to be embedded on the die plate, and dividing flow cone is to be embedded on the supporting plate; The problem that prior art rock quartz plastic floor extrusion die exists is: core is swing easily in die cavity, the extruded stock weak effect that in die cavity, confluxes, and the manufacturing cost of mould is high.

The (3) summary of the invention: the purpose of the utility model is exactly to solve the high problem of manufacturing cost that the existing core of existing rock quartz plastic floor extrusion die is swung in die cavity easily, extruded stock confluxes weak effect and mould in die cavity, provides a kind of unitary core to divide the flow cone extrusion die.

The concrete scheme of the utility model is: a kind of unitary core is divided the flow cone extrusion die; It has die body; Be provided with runner in the die body, the top of die body adopts screw to be separately installed with supporting plate, cylinder manifold, C template, B template and A template, and C template, B template and A template are provided with die cavity; Supporting plate and cylinder manifold are provided with runner, in the die cavity of C template, B template, A template and in the runner of supporting plate, cylinder manifold, die body, core are installed; It is characterized in that: be respectively equipped with the dovetail wing on the core and divide flow cone, cylinder manifold is provided with dovetail groove, and core is there to be the dovetail groove formation on dovetail wing and the cylinder manifold to inlay installation.

Branch flow cone on the described core of the utility model is provided in a side of the lower end of core, and the dovetail wing is provided in a side of core and is positioned at the branch flow cone left and right sides on the upper side.

Dovetail groove on the described cylinder manifold of the utility model is provided in a side of the both sides about the cylinder manifold die cavity.

The utility model is compared with existing rock quartz plastic floor extrusion die; The utility model is with core and divides flow cone to be made as an integrated member; On cylinder manifold, be provided with dovetail groove, and the core and the branch flow cone of integral body are inlayed in the dovetail groove that is installed in cylinder manifold, make core and divide flow cone suffered unbalance loading extruding force in die cavity to be distributed on the cylinder manifold; Eliminated the beat phenomenon of core in die cavity, the conflux effect of extruded stock in die cavity improves; The utility model is with core and divides flow cone to be made as an integral body, reduced the dovetail wing on the core and the dovetail groove on the die plate in the original structure, and the material consumption of mould and processing technology obtain reducing, and the manufacturing cost of mould is reduced; The utility model is simple in structure, effect significantly reaches low cost of manufacture; The utility model preferably resolves the high problem of manufacturing cost that the existing core of existing rock quartz plastic floor extrusion die is swung easily, extruded stock confluxes weak effect and mould in die cavity in die cavity.
