摘要： A method and an apparatus for injection-molding a molten resin wherein any flaw such as warpage, shrinkage or the like does not occur in products having a small thickness when the desired product of injection molded resin is molded by injecting the molten resin into a cavity of an injection molding die. The molten resin is injected into the cavity under proper control with respect to injection speed and pressure, the pressure of the molten resin being temporarily set and reduced to a preset reference value when the cavity is filled with the molten resin, and subsequently, the pressure of the molten resin filled in the cavity is released.

摘要： A support apparatus of an injection-molding machine has a neural network that receives test molding data corresponding to molding conditions and a quality value obtained by measuring a non-defective molded article, and that determines a quality prediction function based on the received test molding data. A computer calculates a predicted value of the quality value using the quality prediction function. An input apparatus inputs into the neural network fixed values for the molding conditions except for a selected at least one of the molding conditions, and inputs a target value of the quality value. A graph generator generates a graphical relationship between the selected at least one molding condition and the predicted value. A graph correction unit corrects the graphical relationship generated by the graph generator on the basis of the target value. A display unit selectively displays the graphical relationship generated by the graph generator and the graphical relationship corrected by the graph correction unit.

摘要： An injection molding control method that uses a neural network is disclosed. The control method determines an injection condition according to a prediction function, a first value, and a second value. The prediction function is implemented in test molding, and the first value and second value are implemented in a measurement step that has a time margin. The injection condition predicted for mass-production molding is determined prior to the injection step, and the need for computation during the injection step is thereby eliminated.

摘要： A provisional temperature estimating mathematical expression is set in accordance with which plasticizing conditions used as terms are to be multiplied by unknown coefficients. Then, a given number of experiments not smaller than the number of the unknown coefficients are conducted while the plasticizing conditions are varied, so as to acquire various experimental data. The unknown coefficients are converted into known coefficient in accordance with the acquired experimental data so as to provide a complete temperature estimating mathematical expression, on the basis of which a plasticized resin temperature and noise-outlet resin temperature are determined arithmetically.

摘要： There is provided an injection apparatus comprised of a heating cylinder which is closed by a front end member having a nozzle. The apparatus is further comprised of a plasticating screw in the heating cylinder in a freely rotating and reciprocating manner, and a plunger connected to the front end of the screw. The plunger has a conical front end in which flow channels are formed. The front end member has a measuring chamber formed therein at an internal central location thereof. The measuring chamber has a predetermined length and an internal diameter which is reduced by 8 to 15% with respect to an internal diameter of the heating cylinder. The diameter of the injection plunger is set almost equal to the diameter of the measuring chamber, whereby the injection plunger is inserted into the measuring chamber in a freely reciprocating manner. A gap is formed on the external peripheral surface of the plunger due to the difference between the heating cylinder internal diameter and the plunger diameter, and the gap functions as a plastication-accelerating block. The block is formed so as to have a distance longer than an injection stroke, whereby uniform plastication is achieved and uneven temperature in the material is eliminated. Further, the plunger advance blocks the gap, which leads to uniform density and precise measurement of the material.
摘要翻译：提供了一种由具有喷嘴的前端构件封闭的加热缸构成的注射装置。该装置还包括一个自由旋转和往复运动的加热缸中的塑化螺杆，以及连接到螺杆前端的柱塞。柱塞具有形成流动通道的锥形前端。前端构件在其中央位置处形成有测量室。测量室具有预定长度和相对于加热缸内径减小8至15％的内径。注射柱塞的直径设定为几乎等于测量室的直径，由此注射柱塞以自由往复的方式插入到测量室中。由于加热缸内径和柱塞直径之间的差异，在柱塞的外周面上形成间隙，并且该间隙用作塑化加速块。该块形成为具有比注入冲程更长的距离，从而实现均匀的塑化，并且消除了材料中不均匀的温度。此外，柱塞前进阻挡间隙，这导致均匀的密度和材料的精确测量。
