The traditional extrusion die is composed of a specific shape of the sizing device and an extrusion mechanism. The extrusion force is applied through the cavity of the mold to extrude the material, and then passes through the cooling device and the cutting device. For products with a specific discontinuous shape, the traditional continuous extrusion mold is not enough, because its shape is not linear or continuous. , which cannot be achieved with traditional continuous extrusion dies.

The front part of the cavity is a trumpet-shaped opening, and the rear part is a rectangular cavity. The mold core is a conical shape with a cross-section at the top, and slightly smaller than the trumpet-shaped opening. The mold core is also connected with an upper connecting rod. The plate is arranged in the rectangular cavity, and its size is the same as that of the inner wall of the cavity, and can move up and down in the rectangular cavity. The lower end of the extrusion plate is also connected with a lower connecting rod, and the upper connecting rod is connected to the lower The rods are provided with file openings that cooperate with each other, the upper part of the upper connecting rod is also provided with a mold handle, and the set of dies and the bottom are also provided with limit blocks that limit the extruded plate from the rectangular cavity, and are used to determine the shape of the final product.

具体实施方式 detailed description

如图1所示，本发明它包括套模和模芯，所述套模是两个半圆柱体通过连接机构连接成的圆柱体，其内部空腔前段为喇叭形开口，后段为一长方形空腔，所述模芯为一顶部有横截面的圆锥形，且略小与所述喇叭形开口，模芯还连接有上部连接杆，挤压板设置在所述长方形空腔内，其大小与空腔内壁的大小相同，可以在长方形空腔内上下活动，所述挤压板下端还连接有下部连接杆，所述上部连接杆和下部连接杆设置有相互配合的锉口，上部连接杆上部还设置有模柄，在套模和底部还设置有限制所述挤压板脱离长方形空腔的限位块，用来确定最后成品的形状。所述上部连接杆和下部连接杆连接组成的外框包裹住套模和模芯。所述连接机构为左右两边各一组的第二螺丝螺母组件。所述套膜空腔内喇叭形窄口长度为长方体上表面一半。所述上部连接杆和下部连接杆的锉口上通过第一螺丝螺母套件固定。 As shown in Figure 1, the present invention includes a cover mold and a mold core. The cover mold is a cylinder formed by connecting two half cylinders through a connecting mechanism. The front section of the internal cavity is a horn-shaped opening, and the rear section is a rectangle. Cavity, the mold core is a conical shape with a cross-section at the top, and slightly smaller than the trumpet-shaped opening, the mold core is also connected with the upper connecting rod, and the extrusion plate is arranged in the rectangular cavity, the size of which is It is the same size as the inner wall of the cavity, and can move up and down in the rectangular cavity. The lower end of the extruded plate is also connected with a lower connecting rod. The upper connecting rod and the lower connecting rod are provided with mutually matching files. The upper part is also provided with a mold handle, and the sleeve mold and the bottom are also provided with a limit block that restricts the extruded plate from leaving the rectangular cavity, so as to determine the shape of the final product. The outer frame composed of the connection of the upper connecting rod and the lower connecting rod wraps the sleeve mold and the mold core. The connecting mechanism is a set of second screw and nut assemblies on the left and right sides. The length of the trumpet-shaped narrow opening in the cavity of the mantle is half of the upper surface of the cuboid. The files of the upper connecting rod and the lower connecting rod are fixed by a first screw and nut set.

合模时，上紧第一螺丝螺母组件固定住上部连接杆和下部连接杆，将粘留质材料放入长方形空腔和喇叭形开口内，在套模上作用向上的力，挤压板相对套模向下运动，同时模芯相对套模向下运动，形成对材料的挤压力和摩擦力，在挤压板运动到限位块后停止运动，待其冷却成型即可成模。 When closing the mold, tighten the first screw and nut assembly to fix the upper connecting rod and the lower connecting rod, put the sticky material into the rectangular cavity and the trumpet-shaped opening, and act upward on the mold, and the extruding plates are opposite to each other. The sleeve mold moves downward, and at the same time, the mold core moves downward relative to the sleeve mold to form extrusion force and friction force on the material. After the extrusion plate moves to the limit block, it stops moving, and the mold can be formed after it is cooled and formed.

开模时，带成品冷却定型后，松开第一螺丝螺母组件将上部连接杆和下部连接杆分开，同时将第二螺丝螺母组件送开，即可开模拿出成品。 When opening the mold, after the finished product is cooled and shaped, loosen the first screw and nut assembly to separate the upper connecting rod from the lower connecting rod, and at the same time send away the second screw and nut assembly to open the mold and take out the finished product.
