Introduction of key equipment extrusion die for plastic profile
As a kind of main plastic building materials, plastic profile has been widely used, especially in plastic doors and Windows. Extrusion die is the key equipment of plastic profile production. Not only its design technology is based on plastic forming process, but also is supported by mechanical design. Moreover, it has its particularity in extrusion die manufacturing, which is directly related to the molding quality of plastic profile.
The main performance in plastic different profile cross section shape is complex, must focus on the precision of the mold cavity design when the design, structure design, etc., which requires corresponding measures in the manufacturing process.
Characteristics of extrusion die structure of plastic profile
1. The shape of the die head mouth mold and injection products section is similar in geometry, material from extruder into geometry is generally round when people die, and then from the circular to make the transition to a similar geometric cross section design, form three functional geometry area, namely the feeding part of the transition part molding part. The material flow from the extruder is followed by the preforming plate of the preformed plate of the plate compression plate. The form of stereotyped mode is different due to different methods, but generally it includes three parts of the functional elements and parts of the water cooling system and vacuum adsorption system. The extrusion die structure can be seen from the extrusion die structure. The extrusion die is a type of mold, which is different from other plastic mould.
2. The extrusion die is designed according to the requirement of the customers, rarely appears the same cavity, so in production each kind of parts need programming, so programming is a very important link in production. The molten plastic is gradually formed near the shape of the product through the shunt compression, so the change of its cavity is very complicated.
General import four axis linkage four coordinate wire-cutting built-in software can realize abnormity of nc programming, also can use powerful CNC programming software or they have the following functions:
(1) powerful post-processing function, able to support the common line cutting system, and can meet the special needs of customers by modifying the reprocessing program.
(2) can identify multiple format graphics files, such as the format. The easy choice of machining path can be selected according to the need to select the machining path by line segment in the complex graph, so as to observe the relationship between the machining path and other parts of the parts.
(3) have the function of three-dimensional observation, in different top processing, program plane and corresponding auxiliary plane need reasonable figure yuan, otherwise will produce distortion processing shape, form the transition is not correct. These unreasonable transitions can be found through three-dimensional observation of software.
