【発明の詳細な説明】
本発明は水平式コールドチャ／パ履ダイカスト機に用い
る金製に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gold plate for use in a horizontal cold-char/paddle die-casting machine.
水平式コールドチャンバ蓋ダイカスト憾では、射出スリ
ーブ内に溶湯をＷｄ嚇し射出すると、射出の際に射出ス
リーブ内の空気を１１１′ｉＩＩ内に巻き込み、製品の
品質低下をもたらす欠点があった。In horizontal cold chamber lid die casting, when the molten metal is injected into the injection sleeve using Wd, the air inside the injection sleeve is drawn into the 111'iII during injection, resulting in a deterioration in the quality of the product.

人蓋（Ｍ−充填率）が少ないとＭ−があった。For this purpose, conventional die casting methods have been used, such as the vacuum method to expel the air inside the cavity and the injection sleeve, and the wax spray method, which exchanges the air with reactive gas such as oxygen or other bubbles. However, in all cases, there was M- when the injection sleeve had a low filling rate (M-filling rate).

んとするものである。Also, with this tie-casting, there is no lump Ih inside the injection sleeve.
If the roundness rate is low, the molten metal will solidify faster and the same phase will increase,
This will lead to low product quality and will endanger the life of the injection sleeve, plunger nozzle, and metal lid. In view of the shortcomings of the conventional method, Togiri Kuki originally developed a method for l1iI even when the II-filling rate in the injection sleeve was low.
From 116 o'clock to the time of injection, the m-light mechanism in the injection sleeve is raised at an upper angle, and the IM for tie-casting is completely fixed for 14 s, which can solve the battle between the air writing layer and one-phase generation. It is something to do.

It is installed in the sprue part (4a) of the ltl Homare JIG 4) in a set manner, and slides back and forth freely within the injection sleeve (υ) by a careful means.In other words, during hot water supply and injection, the inside of the injection sleeve (1) 7 Ranjya tips (approaching the phrase,
When injection is completed (casting), it moves out of the injection sleeve (1) and into the movable metal (4). The mechanism for operating this counter screw (7) is as follows:

Or, as well as building a castle to support Rendo, the town - Soji (4
In the former case, the cylinder (9) is used to reciprocate and reciprocate inside the injection sleeve (1). : In the case of #, the injection sleeve (Q) reciprocates and slides freely in and out due to the elastic force of the elastic spring ring and the pressing force of the plunger tip (6).

ィ軸内へ鋳込み、射出動作を完ｒする。The cylinder (9) that performs the injection operation can also be used as a cylinder for drawing out the core, and the counter piston (7) is set according to the amount of hot water supplied to #'i melt during hot water supply. Close to the plunger tip (6), a temporary weir is formed in the injection sleeve (mm) with the slot (5) in between. In this state 1, supply a predetermined amount of hot water from the hot water supply port (5), increase the filling rate in the injection sleeve (υ), and perform the injection operation.Then, the plunger tip (6) In conjunction with the injection operation, the counter piston/(7) moves toward the ITm gold 11t(4) side, and at the beginning of the injection operation, the plunger tip (~ and the threshold 11i1() between the counter piston/(7)) 4) is retained, and the counter piston (7
) is housed in the recess 111 (resembling IIIPl) of the movable metal amount -) and stops, and the plunger tip (Xu) continues to inject the molten metal into the cavity axis. Complete the injection operation.

で既設のダイカスト礪にも簡単に一用できる。Next, the plunger tip (when the phrase is retracted, the cylinder (9) in Fig. 1
) enters the injection sleeve (1) and stops at the position at which hot water is supplied, and in the case of the one in Figure 2, the counter piston (7) moves into the injection sleeve (7) due to the elastic force of the elastic spring (2). In this way, the present invention provides a counter-height device at the sprue, allows the counter-piston to freely protrude into the injection sleeve, and connects the plunger tip to the counter-piston. Since the molten metal is supplied and injected in between, even if the molten metal filling rate in the injection sleeve is originally low, the counter piston protrudes into the injection sleeve and a temporary dam is formed inside the injection sleeve. From the time of supply to the time of injection, the filling rate of molten metal in the injection sleeve can be increased to approximately 100X.Therefore, the problem of air entrainment, which occurred due to the low filling rate of molten metal in the injection sleeve, can be reduced to a solid phase. This completely solves the problems that occur, and makes it possible to provide superior die-casting products.Furthermore, it can be easily applied to existing die-casting chambers by simply replacing the metal parts.
よって、所期の目的を達成し得る１、Therefore, the desired purpose can be achieved 1.
