Abstract
The invention discloses a door/window sealing strip extrusion mold which comprises a disc-shaped mold base plate, wherein an extrusion through hole array consisting of circular extrusion through holes is formed on the upper surface of the mold base plate; a prism cylinder array consisting of hollow prism cylinders is arranged on the lower surface of the mold base plate. According to the door/window sealing strip extrusion mold, prism-shaped extrusion holes are changed into the circular extrusion through holes, so that the extrusion resistance of plastic particles is effectively reduced, and the extrusion speed of sealing strips is effectively increased. As the extrusion resistance of the plastic particles is low, the surfaces of the sealing strips are relatively smooth, and the hollow rate is remarkably reduced. The door/window sealing strip extrusion mold is simple in structure, remarkable in effect and high in practicability.
Description
Technical Field
The invention relates to a plastic extrusion device, in particular to an extrusion die for door and window sealing strips.
Background
The door and window sealing strip is mainly applied to sealing operation of building decoration doors and windows such as plastic-steel doors and windows, aluminum alloy doors and windows, wood doors and windows and the like, and is generally formed by extruding PVC and other materials. The existing sealing strip is prism-shaped in the extrusion hole and the extrusion hole of the extrusion die, the extrusion speed of particles is slow, and the production efficiency is influenced. If the extrusion pressure is forcibly increased, the hollow rate of the sealing strip is easily increased, and the product quality is affected.
Disclosure of Invention
The invention mainly solves the technical problems in the prior art, and provides an extrusion die for door and window sealing strips.
The technical problem of the invention is mainly solved by the following technical scheme:
the utility model provides a door and window sealing strip extrusion tooling, door and window sealing strip extrusion tooling contain a discoid mould base plate, the upper surface of mould base plate on be equipped with the crowded material through-hole array of constituteing by the circular shape crowded material through-hole, the lower surface of mould base plate on be equipped with the prismatic section of thick bamboo array of constituteing by hollow prismatic section of thick bamboo.
As a preferred embodiment of the invention, the prism cylinder is a hexagonal prism straight cylinder.
As a preferred embodiment of the invention, the door and window sealing strip extrusion die is integrally formed by die steel.
The door and window sealing strip extrusion die changes the prismatic extrusion holes into the circular extrusion through holes, thereby effectively reducing the extrusion resistance of plastic particles and effectively improving the extrusion speed of the sealing strips. The extrusion resistance of the plastic particles is reduced, so that the surface of the sealing strip is smoother, and the hollow rate is also obviously reduced. The door and window sealing strip extrusion die is simple in structure, obvious in effect and high in practicability.

FIG. 2 is a schematic perspective view of the extrusion die for a weatherstrip of a door or window of FIG. 1, taken from another perspective;
FIG. 3 is an enlarged detail view of region A of the weatherstrip extrusion die of FIG. 1;
FIG. 4 is an enlarged detail view of the extrusion die for a weatherstrip in the area B of FIG. 2;
wherein,
1. door and window sealing strip extrusion tooling; 2. a mold substrate; 3. extruding through holes; 4. a prismatic tube.
Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention will be more clearly and clearly defined.
As shown in fig. 1 to 4, the door/window sealing strip extrusion die 1 of the present invention includes a disk-shaped die base plate 2, wherein a material extruding through hole array composed of circular material extruding through holes 3 is disposed on an upper surface of the die base plate 2, and a prism cylinder array composed of hollow prism cylinders 4 is disposed on a lower surface of the die base plate 2.
The prism barrel 4 is a hexagonal prism straight barrel.
The door and window sealing strip extrusion die 1 is integrally formed by die steel.
Without being limited thereto, any changes or substitutions that are not thought of through the inventive work should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
