Abstract
The invention discloses a thermostatic controllable foaming machine head for plastic (PLA) sheets. The thermostatic controllable foaming machine head comprises a machine head body, a core rod, an outer die body and an inner die body; the fixed core rod is arranged in the cavity of the machine head body; the outer die body is fixed at the rear end of the machine head body; the inner die body is sleeved at the rear part of the core rod; a feeder is fixed at the front opening of the machine head body; heating oil passages are formed in the machine head body and the core rod; the interface of the heating oil passage is led out of the outer surface of the machine head body to form an oil passage opening; and the oil passage opening of the machine head body is connected with a die temperature controller through the oil passage. According to the thermostatic controllable foaming machine head for producing the PLA physical extruded foamed sheets, the purpose of thermostatic control can be fulfilled through the mold temperature controller, and products with exquisite surface, regular shape and qualified quality are obtained.
Description
Technical field
The present invention relates to the controlled foaming die of a kind of PLA sheet material constant temperature, belong to macromolecular material plasticity processing production equipment.
Background technology
During the first-born product of common machine, the bad adjusting of temperature range is controlled, and temperature error is large, can only satisfy the production of common sheet material and use.PLA is biological plastics, has lower melt strength, higher shearing sensibility and higher heat-proof quality, can be harsher to temperature requirement when these characteristics explanations are produced sheet material with PLA, and common production can't reach the requirement of producing the PLA sheet material with head.
Summary of the invention
The purpose of this invention is to provide the controlled foaming die of a kind of PLA sheet material constant temperature, solving common production head can not thermostatic control, can't reach and can uninterruptedly produce continuously the difficult problem of qualified PLA sheet material.
The objective of the invention is to realize as follows: the controlled foaming die of this PLA sheet material constant temperature, comprise handpiece body, plug, outer die body, interior die body, stationary core rod in the inner chamber of handpiece body, outer die body is fixed in the rear end of handpiece body, the rear sleeve of plug has interior die body, and the handpiece body prosopyle is body of feedstock fixedly, and the oil duct of heating is set in handpiece body and plug, the interface of oil duct of heating is drawn on the handpiece body outer surface and is formed oil duct junction, and the oil duct junction on handpiece body is by oil circuit connection mode temperature controller.Realize that by the mould temperature controller head thermostatic control satisfies the production temperature, thereby reach the requirement of smooth production sheet material.
The front end setting of plug is in the shunting body with the cone point of body of feedstock endoporus, makes the head charging even.
Interior die body is position, front and back adjustable structure on plug, in order to adjust the outlet gap of interior die body and outer die body.
During production, preheat assigned temperature by heating system, the PLA material after the main frame plasticizing enters this device through body of feedstock, makes it shunting through shunting body, changes molecularly oriented, becomes sheet material after outer die body, interior die body.Regulate outer die body, interior die body relative position and can produce the product of different size, according to producing product appearance and quality condition by regulating the temperature of mould temperature controller and then control and regulation handpiece body.
The present invention produces PLA physics extrusion foaming sheet material, can reach thermostatically controlled purpose, and then obtains surface exquisiteness, regular shape, up-to-standard product.
