Description

A kind of mold of controllable profile shapes local material extruded velocity
Technical field
The utility model relates to Profile Extrusion production mould technical fields, more particularly, to a kind of controllable profile shapes office The mold of portion's material extruded velocity.
Background technique
Known, for existing profile shapes often with more complex contour structures, result leads to the profile shapes office in production The extruded velocity of portion's material is inconsistent with material of main part, and final products appearance is caused raised grain defect locally occurring.To solve This problem is solved in mold processing and die trial stage by modifying the method for mold cavity.But in actual production, if made When being changed with different extruder or material, the extruded velocity and the inconsistent problem of material of main part of profile shapes local material Can occur again, therefore can only be solved by the method for modifying mold cavity again.It is more serious, or even because repeatedly modifying mold Type chamber and cause mold to be scrapped, bring economic loss to enterprise.
Summary of the invention
According to the extruded velocity for the existing profile shapes local material mentioned in background technique and material of main part inconsistence problems, The utility model discloses a kind of mold of controllable profile shapes local material extruded velocity, uses and increase gas in preceding die plate The method in road and air control shutter, the temperature of die orifice template chamber before local modulation, to realize that control profile shapes local material is squeezed Speed out reaches the consistent purpose of material extruded velocity.
In order to realize the goal of the invention, the utility model adopts the following technical solution: a kind of controllable profile shapes part The mold of material extruded velocity, including including die body, transition plates, core mold plate, compression plate, preceding mouth template, rear mouth template, plug; The die body, transition plates, core mold plate, compression plate, preceding mouth template, between rear mouth template by positioning finger setting, be connected with Together;The plug is fixed in core mold plate, and front end extends in die body type chamber, and rear end extends in sizing model cavity;Institute Mouth template has air ducting system before stating, and air ducting system includes air intake duct, main airway, gas off-take;The main airway and prosopyle stencil-type Cavity material extrusion direction is parallel, the type chamber of extruded velocity need to be controlled by nearby die plate, there is plug closure at main airway both ends;Main gas Road both ends there are also air intake duct and gas off-take, air intake duct close to preceding mouth template feed end, gas off-take close to preceding mouth template discharge end, into Air flue and gas off-take opening are located at preceding mouth template same side, and have connection screw thread.
Further it is improved technology scheme, air control shutter is installed with screw thread in the opening of gas off-take, adjusts air flue Interior air velocity, for accurately adjusting the local temperature of prosopyle stencil-type chamber.
It is further improved technology scheme, air ducting system is connected with hot-air, the part of prosopyle stencil-type chamber is heated, for mentioning The extruded velocity of high profile shapes part.
It is further improved technology scheme, air ducting system is connected with cold air, reduces the local temperature of prosopyle stencil-type chamber, uses In the extruded velocity for reducing profile shapes part.
Due to the adoption of the technical scheme as described above, the utility model has the following beneficial effects:
A kind of mold of controllable profile shapes local material extruded velocity described in the utility model increases in preceding die plate Air ducting system and air control shutter are connected with hot-air or cold air in air flue, adjust hot-air or cold air with air control shutter Flowing velocity, achieve the purpose that accurately to adjust prosopyle stencil-type chamber local temperature, thus realize control profile shapes local material Extruded velocity reaches the consistent purpose of material extruded velocity.This structure changes in the past different to solve by modification mold cavity The extruded velocity and the inconsistent method of material of main part of profile local material are avoided in actual production if squeezed using different When machine or profile shapes material change out, need to modify mold scrap problem caused by mold cavity repeatedly.

Specific embodiment
By the following examples can detailed explanation the utility model, open the purpose of this utility model is intended to protect All technological improvements in the scope of the utility model.
A kind of mold of controllable profile shapes local material extruded velocity, including die body 1, transition plates 2, core mold plate 3, compression Plate 4, preceding mouth template 5, rear mouth template 6, plug 13;The die body 1, transition plates 2, core mold plate 3, compression plate 4, preceding mouth template 5, after By positioning finger setting, being bolted together between mouth template 6;The plug 13 is fixed in core mold plate 3, and front end extends Into 1 type chamber of die body, rear end is extended in sizing model cavity;5 plate of preceding mouth mold has air ducting system, and air ducting system includes air inlet Road 7, main airway 8, gas off-take 9;The main airway 8 is parallel with preceding 5 impression material of mouth template extrusion direction, close to control extrusion There is plug closure at the cavity portion of speed, 8 both ends of main airway;There are also air intake duct 7 and gas off-take 9, air intake ducts 7 at main airway 8 both ends Close to preceding 5 feed end of mouth template, gas off-take 9 is located at preceding mouth mold close to preceding 5 discharge end of mouth template, air intake duct 7 and the opening of gas off-take 9 5 same side of plate, and have connection screw thread;The outlet road junction is equipped with air control shutter 12 with screw thread.
When mode transfer, material is squeezed by 1 feed inlet of die body, by die body 1, transition plates 2, core mold plate 3, compression plate 4, preceding mouth mold The type chamber of plate 5, rear mouth template 6 is squeezed out from rear 6 exit of mouth template.The discharging speed feelings of 6 exit material of mouth template after observation Condition, if it find that it is passed through hot-air in the air ducting system of preceding 5 corresponding position of mouth template when local material extruded velocity is slower, Air control shutter 12 is adjusted, until material extruded velocity is consistent;If it find that when local material extruded velocity is very fast, in corresponding position It is passed through cold air in the air ducting system set, adjusts air control shutter 12, until material extruded velocity is consistent.After the completion of mode transfer, i.e., It can normally put into production.
More than, the only preferable specific embodiment of the utility model, but the protection scope of the utility model is not limited to In this, anyone skilled in the art within the technical scope disclosed by the utility model, skill according to the present invention Art scheme and its utility model design are subject to equivalent substitution or change, should be covered within the scope of the utility model.
