Abstract
The utility model relates to improvement of a plastic profile extruding die, in particular to a plastic profile oval die core extruding die which comprises a confluence plate and three templates. Cavities are arranged on the three templates, two bosses are symmetrically arranged on the left side and the right side of each cavity, cores are installed in the cavities of the three templates, two grooves are respectively and inwards arranged on two sides of each core, and two die cores are respectively installed in two cavity bodies formed by the two bosses in each cavity and the two grooves in each core. The plastic profile oval die core extruding die is characterized in that two grooves on each core are of oval structures, and die cores arranged in cavities and the two grooves of each core are of oval structures. The plastic profile oval die core extruding die solves the problems that an existing plastic profile forming hole boss structure extruding die is prone to be out-of-round in forming hole bosses and poor in forming quality of plastic profiles and is mainly used for improving the existing plastic profile forming hole boss structure extruding die.
Description
(i) technical field: the utility model relates to the improvement of plastic profiled bar extrusion die, is the oval core rod extrusion die of a kind of plastic irregular profile.
(ii) background technology: plastic irregular profile is that extrusion die is the critical piece of plastic shaped material forming by processing by extruder and extrusion die after grain plastic and curing agent heat fused, and extrusion die can be divided into European and American; Prior art with the problem of the American plastic profile extruding die existence of forming hole boss structure is: the forming hole boss structure of plastic irregular profile easily loses circle, and the Forming Quality of plastic irregular profile is poor.
(iii) summary of the invention: the purpose of this utility model is exactly to solve the poor problem of Forming Quality that the existing forming hole boss of existing plastic irregular profile forming hole boss structure extrusion die easily loses circle and plastic irregular profile, and the oval core rod extrusion die of a kind of plastic irregular profile solution is provided.
Concrete scheme of the present utility model is: the oval core rod extrusion die of a kind of plastic irregular profile, and it has cylinder manifold, and cylinder manifold is provided with crowded material mouth; The top of cylinder manifold adopts screw to be connected with respectively A template, B template and C template, on A template, B template and C template, is equipped with die cavity, and the both sides of three template die cavity left and right all are arranged with concave station; In die cavity in three templates, core is installed, the concave station place, two of left and right that core is positioned at die cavity inwardly is provided with respectively two grooves, in two cavitys that two concave stations in die cavity and two grooves in core form, is separately installed with two core rods; It is characterized in that: two grooves on described core are oval structure, and the long axis direction of oval structure groove is vertical with the chamber wall of two concave stations on die cavity; Described core rod is oval structure, and the long axis direction of oval structure core rod is identical with the long axis direction of two oval structure grooves.
Die cavity on A template described in the utility model, B template and C template is the overlapping installation of aliging up and down.
The utility model is compared with existing plastic irregular profile forming hole boss structure extrusion die, the utility model is that two grooves and two core rods in the original structure core are changed to oval structure by circular configuration, can realize that the oval forming hole boss after moulding becomes circular forming hole boss after the contraction distortion through inserts, molding effect is remarkable, and the Forming Quality of plastic irregular profile is improved; The utility model is simple in structure, effect significantly reaches applied range; The utility model preferably resolves the poor problem of Forming Quality that the existing forming hole boss of existing plastic irregular profile forming hole boss structure extrusion die easily loses circle and plastic irregular profile.

(v) the specific embodiment:
Embodiment: the oval core rod extrusion die of (referring to Fig. 1) a kind of plastic irregular profile, it has cylinder manifold 8, and cylinder manifold 8 is provided with crowded material mouth 9; The top of cylinder manifold 8 adopts screw 2 to be connected with respectively A template 1, B template 6 and C template 7, be equipped with die cavity 3(on A template 1, B template 6 and C template 7 and refer to Fig. 1, Fig. 2), the both sides of three template die cavity 3 left and right all are arranged with concave station 10(and refer to Fig. 3); In die cavity 3 in three templates, core 4 is installed, concave station 10 places, two of left and right that core 4 is positioned at die cavity 3 inwardly are provided with respectively two groove 11(and refer to Fig. 2, Fig. 4), be separately installed with two core rods 5 in two cavitys that two concave stations 10 in die cavity 3 and two grooves 11 in core 4 form; Particularly: two grooves 11 on described core 4 are oval structure (referring to Fig. 4), and the long axis direction of oval structure groove 11 is left and right directions and arranges; Described core rod 5 is oval structure (referring to Fig. 5), and the long axis direction of oval structure core rod 5 is left and right directions and arranges.
Die cavity 3 on the described A template 1 of the present embodiment, B template 6 and C template 7 is the overlapping installation (referring to Fig. 1) of aliging up and down.
