Abstract
A constant-temperature controllable PLA (polylactic acid) sheet foaming machine head comprises a machine head body, a mandrel, an outer mould and an inner mould. The mandrel is fixed in the inner cavity of the machine head body, the outer mould is fixed at the rear end of the machine head body, the inner mould is sleeved at the rear of the mandrel, a feeding unit is fixed at the front port of the machine head body, oil heating channels are arranged in the machine head body and the mandrel, the joint of the oil heating channels extends out of the outer surface of the machine head body to form an oil channel port, and the oil channel port on the machine head body is connected with a mould temperature controller by the aid of an oil channel. When the constant-temperature controllable PLA sheet foaming machine head is used for producing extruded physically-foamed PLA sheets, constant-temperature control can be realized by the aid of the mould temperature controller and qualified products with smooth surfaces and in regular shapes can be produced.
Description
Technical field
The utility model relates to the controlled foaming head of a kind of PLA sheet material constant temperature, belongs to macromolecular material plasticity processing equipment.
Background technology
The bad adjusting control of temperature range during the first-born product of common machine, temperature error is big, can only satisfy the production of common sheet material and use.PLA is a biological plastics, has lower melt strength, higher shearing sensibility and higher heat-proof quality, can compare harshness 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 the utility model provides the controlled foaming head of a kind of PLA sheet material constant temperature, and solving common production head can not thermostatic control, can't reach the difficult problem that can uninterruptedly produce qualified PLA sheet material continuously.
The purpose of the utility model realizes as follows: the controlled foaming head of this PLA sheet material constant temperature comprises 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 portion of plug is with the internal mold body, and the handpiece body prosopyle is the charging body fixedly, and the oil duct of heating is set in handpiece body and the 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 the handpiece body is through oil circuit connection mode temperature controller.Satisfy the production temperature through the thermostatic control of mould temperature controller realization head, thereby reach the requirement of smooth production sheet material.
The front end setting of plug is in the branch fluid that has the awl point of charging body endoporus, makes the head charging even.
Interior die body is a front and back adjustable positions structure on plug, in order to the outlet gap of die body in adjusting with outer die body.
During production, preheat assigned temperature by heating system, the PLA material after main frame plasticizing gets into this device through the charging body, makes it shunting through dividing fluid, changes molecularly oriented, through outside become sheet material behind the 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 through regulating the temperature of mould temperature controller and then control and regulation handpiece body.
The utility model is produced PLA physics extrusion foaming sheet material, can reach thermostatically controlled purpose, and then obtains surface exquisiteness, regular shape, up-to-standard product.
