Technical Field
The application relates to the technical field of plastic extrusion molding, in particular to an online rapid adjustment molding mechanism.
Background
The plastic extrusion molding production process is continuous and stable production. The factors affecting continuous stable production are numerous, and on-line control of molding is a very important aspect.
The plastic extrusion molding production process is a dynamic process and has wide application range. After the die is designed and manufactured, the qualified product is produced, and an repeated debugging process is needed in the middle. On the one hand, it is very important that the molten billet extruded from the die head smoothly enters the shaping die, especially for the profile materials such as pure single arm large wall thickness.
In the existing extrusion molding production process of the die, due to the particularity of the end face of the profile, for example, for a very large profile of a pure single arm, if the die head is also designed into a profile, the die head is designed to be complex and can not realize on-line control of discharging, the production and the debugging are very difficult, and if the die head is designed into an adjustable sheet type plate die, the workload of die head design and debugging can be greatly simplified. In order to allow a shaped preform, which is designed as a straight-line, to enter the shaped mold smoothly, the process has a device for pre-modifying the shape. While the preform with a small wall thickness is easily changed to the desired shape for the preform where the local variation is too large, it is more difficult to change the preform to the desired shape where the local variation is large as the wall thickness is increased. In order to produce qualified products, the debugging times of the die are not increased, and parts of the die are replaced, so that the production period of the die is prolonged while the cost is increased.
