摘要： Upward variations of a molten metal level in a container for melting metallic material shall be carried out by detecting variations of a liquid level inside a detector connected to a gas-pipeline, wherein a rise in the pipeline pressure causes the liquid level to move down. Communication is established by means of a gas-pipeline 13 for inert gas between that portion of a container for melting metallic material which is above a molten metal surface 15a and that portion of a detector 16 comprising a transparent tubular container 18 which is above a liquid surface 17a. Variations of the liquid level 17a inside the detector 16 due to a rise in the pressure inside the above-mentioned gas-pipeline 13 are detected as upward variations of the level of the molten metal surface.

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： A first direction shifting valve adapted to supply pressurized hydraulic oil to a hydraulic chamber on the rearward displacement side and discharge hydraulic oil from the hydraulic chamber on the rearward displacement side, and moreover, discharge hydraulic oil from a hydraulic chamber on the forward displacement side is disposed in a hydraulic path extending between a hydraulic pump and an injection cylinder. In addition, a second direction shifting valve adapted to supply pressurized hydraulic oil to a chamber on the forward displacement side is disposed in the foregoing hydraulic path. Additionally, a third direction shifting valve is disposed to build a bleeding-off circuit in cooperation with the second direction shifting valve. While a hydraulic path on the rearward displacement side is blocked by the third direction shifting valve, a hydraulic path on the forward displacement side is hydraulically connected to the tank side. When the third direction shifting valve is shifted to the opposite side so that the hydraulic path on the rearward displacement side is hydraulically connected to the tank side and the hydraulic path on the forward displacement side is blocked by the third direction shifting valve, an injection molding operation can be started. With such construction, a rising time of each injection molding operation can be shortened while pressurized hydraulic oil is preliminarily exerted on the hydraulic chamber on the forward displacement side under the bleeding-off condition.
