摘要： An injection screw comprise a rear end to a front end of an effective length of the screw compartmented in the order of a feed zone, a compression zone and a metering zone, wherein the metering zone is constituted by the first metering zone, the second metering zone and the relaxation zone. A root diameter of the second metering zone is formed in a smaller diameter than a root diameter of the first metering zone and a screw channel depth is set deeper than a screw channel depth of the first metering zone. Variations in a resin temperature at injecting is solved and melting and kneading through a entire screw further are improved by only partial changing of the configuration of the metering zone.

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。

摘要： An injection molding apparatus of a metal material places a heating cylinder in an inclined position. The heating cylinder includes a nozzle at a tip thereof and a screw disposed inside. In this way, the metal material in a liquid phase state can be transferred and metered accurately in a reliable manner at all times by flowing due to the inclination and a transfer force produced by rotation of the screw. A clamping apparatus is provided to oppose the injection apparatus and includes a mold having a sprue bush inside. The injection apparatus and the clamping apparatus are placed on an apparatus platform in an inclined position at the same angle with the mold in a lower end, so that the metal material in the liquid phase state in the heating cylinder flows down toward the head due to self-weight. The nozzle and sprue bush are positioned on the same straight line, thereby maintaining nozzle touch without bending the nozzle.

摘要： An improved method of manufacturing a multilayer molding having a core and a surface layer by means of a double nozzle structure can eliminate a damaging phenomenon of producing a mixture of a resin material for forming the core remaining in and out of the aperture of the inner nozzle of the double nozzle structure and a resin material for forming the surface layer in the initial stages of molding operation by effectively driving back the remaining resin into the inner nozzle. A double nozzle structure that can suitably be used with such a method includes a shut-off pin arranged in the inner nozzle disposed at the center of the outer nozzle. The resin material for forming the core is driven out simultaneously with the resin material for forming the surface layer coming from the outer nozzle. The operation of resin injection from the inner nozzle is terminated at an arbitrarily selected moment during the operation of injecting the resin material for the surface layer of the outer nozzle. Then, the inside of the inner nozzle is brought into a no-load condition while the shut-off pin is held to its open position. Thereafter, the remaining resin material for the core found in and out of the aperture of the inner nozzle is driven back into the inner nozzle by the pressure of the resin injected from the outer nozzle. Finally, the inner nozzle is closed by the shut-off pin and the injecting operation of the outer nozzle is terminated.

摘要： A method of metering a metal material in a liquid phase in molding injection provides accurate and reliable transfer of the metal material. A heating cylinder housing a rotatable and axially movable screw, is inclined with its head pointing downward, so that the metal material in the liquid phase state flows down into a front chamber due to self-weight. At the forward position after injection, the screw is forced to retract to a set position, whereby a predetermined quantity of a liquid phase material primarily stored on the periphery of the head portion of the screw is accumulated by suction due to a negative pressure in the front chamber of the heating cylinder. Further, a constant quantity of the liquid phase material can be metered each time in the front chamber by stopping and then rotating the screw at a retraction position.
