Abstract

PURPOSE:To prevent a steel wire rope from deviating to one of terminal parts and to prevent the disconnection accident of both in the stage of inserting the terminal part by casting into the terminal of the steel wire rope by supporting the terminal part of the wire rope with stanchions for preventing the movement of the wire rope and performing casting. CONSTITUTION:A lower die 3' and upper die 3'' of a die 3 provided with cavities 31, 32 are mated. A block 4 is bolted 5 to the die 3' and a spring plate 6 to sandwich a steel wire rope 1 is provided thereto. Ejector pins 7, 7 are slidably provided to the die 3' and a sprue 8 is provided to the die 3'' to admit a molten metal into the cavities 31, 32. At least >=2 pieces of stanchion pins 9 of which the top ends are pressed to the wire rope 1 and which support the wire rope from both sides so as not to allow the wire rope to move even under the inflow pressure of the molten metal are embedded into the dies 3'', 3' so as to project into the cavity 32. When the molten metal is poured under pressure into the die 3 mated with dies 3'', 3' through the sprue 8 thereof, the molten metal solidifies in the cavities 31, 32 and encloses the end part of the rope 1 into the axial central part. A terminal part 2 having continuous reinforcing leg parts 22 leaving blanked holes 23 formed after removal of the stanchions 9 in the detaining part 21 and the body part thereof is thus molded.

鋳造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention provides an end part of a steel cable, a steel shaft, etc., in which metal or synthetic resin is integrally molded by casting or injection molding. It is related to the casting method that lasts a long time.

にして関連機器に連結する様にされている。When a terminal part for locking is cast and molded to the end of a steel cable or shaft and attached to the end, the tip of the steel cable is bulged out as in Utility Model Publication No. 55-35457, and a locking part is molded in that part to lock it. Continuously wrap the cable around the section and form column-shaped reinforcing legs.
The cable is connected to related equipment in a manner that improves the joint strength between the two and prevents the cable from breaking.

脱する事故が発生する。However, in the conventional method, as shown in Fig. 1, when casting parts, the steel cable 1 moves due to the casting pressure of the molten metal, and the end part 2
It is difficult to locate the center of the locking portion 21. and reinforcing legs 22
It is often biased towards one side. In this case, when a slight pulling or pushing load is applied to the thinned part, the inside of the casting will crack, the locking part 21 and the reinforcing leg part 22 will separate, the terminal part 2 will be damaged, and at the same time the steel cable 1 will be attached to the locking part 21. An accident occurs in which the vehicle slips out of the vehicle and both parties break away.

鋼索端末を鋳ぐるみ鋳造するに当り、索が端末部品の中
央部に位置する様に、鋼索の端末部分を索移動防止用の
支柱で支持させるようにした金型をもって鋳造するもの
である。In order to solve this problem, the present invention has been developed to provide an end part of a steel cable with a strut for preventing the cable from moving, so that the end part of the steel cable is placed in the center of the end part when casting the end part of the steel cable. It is cast using a mold that is supported by

本発明を図面によって説明すると第２図の様ツク４をボ
ルト５で取付け、之に鋼索ｌを挾持を設け、空部３１及
び３２に溶湯が流入されるようにされている。To explain the present invention with reference to the drawings, as shown in FIG. 2, a hook 4 is attached with a bolt 5, and a steel cable 1 is provided with a clamp, so that molten metal flows into the cavities 31 and 32.

更に空部３２には、先端は鋼索１に当て、その両側より
之を支持して、溶湯の流入する圧力てんでいる。Furthermore, the tip of the hollow portion 32 is placed against the steel cable 1, and is supported from both sides to provide pressure for the molten metal to flow into the hollow portion 32.

支柱ピン９は鋼索１の太さに合わせて大きさが変えられ
る。The size of the strut pin 9 can be changed according to the thickness of the steel cable 1.

している端末部品２が成型される。When molten metal such as zinc die-casting is injected under pressure from the sprue 8 of the mold 3 that combines N'''r and Tesha a, the molten metal is injected into the cavities 31 and 32 and solidified, as shown in Fig. 3. A terminal part 2 is molded in which the end of the steel cable 1 is enclosed in the shaft core, and the locking part 21 and the reinforcing leg part 22 are continuous with the retaining part 21 and the body part thereof leaving a hole 23 through which the support column 9 passes.

本発明は鋼索１が動かぬ様支柱ピン９を当て＼支承させ

ない。故に偏肉部を生ぜず両者の接合強度は強いものが
得られる。In the present invention, the steel cable 1 is cast with support pins 9 supported so that the steel cable 1 does not move, so the steel cable 1 does not become eccentric within the terminal part 2. Therefore, a strong bond between the two can be obtained without causing uneven thickness.
