Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a shaft supply structure for automatically sequentially supplying shafts to be inserted into a mold in an automatic shaft insert molding apparatus.

An automatic shaft insert molding device is a device that automatically creates a molded product by sequentially supplying shafts to a mold, embedding the shafts, and molding.

This invention aims to provide a shaft supply structure for automatically supplying a shaft to a mold in this type of automatic shaft insert molding apparatus.

Hereinafter, the shaft supply structure according to this invention will be specifically explained based on the illustrated embodiment.

FIG. 1 is a partial sectional view of an automatic shaft insert molding apparatus showing a shaft supply structure according to this invention. FIG. 2 is a view in the direction of the - line arrow. Reference numeral 1 in the figure indicates an insert plate that is fixedly held in an automatic shaft insert molding machine. insert plate 1
has a rectangular plate shape, and has a circular hole 1a in the center. A shaft feed passage 1b is bored from one outer surface of the insert plate 1 as shown in FIG. 2, and the shaft feed passage 1b communicates with the circular hole 1a in the center. A disc-shaped rotating drum 2 is housed in the circular hole 1a so as to be substantially inscribed therein. Shaft holding grooves 2a are formed every 90 degrees in the axial direction on the outer periphery of the rotating drum 2, and is rotatably supported by a central shaft 3. A gear 4 is fixed to the central shaft 3, and the gear 4
meshes with the motor gear 6 via the intermediate wheel 5. Therefore, the rotation of the motor 7 is caused by the rotation of these gears 6, 5, 4.
is transmitted to the rotary drum 2 via the rotary drum 2, causing the rotary drum 2 to rotate. The shaft 8 is fed into the shaft feeding passage 1b from the outside, and the shaft 8 is always aligned and stored in the shaft feeding passage 1b. Therefore, when the rotating drum 2 rotates, the shaft 8 is sequentially moved into the shaft holding groove 2a as the drum 2 rotates.
Go in one book at a time. Then, the rotating drum 2 stops at a fixed position. On the other hand, a protruding plate 9 is provided on one side of the insert plate 1 so as to face each other, and the protruding plate 9 is made reciprocating in the axial direction of the rotary drum 2 by appropriate means. On the protruding plate 9,
Four ejector rods 10 are erected, each corresponding to the shaft holding groove 2a of the stopped rotating drum 2. By reciprocating the ejector plate 9, it is inserted into the shaft holding groove 2a and pulled out from the shaft holding groove 2a. When the ejector rod 10 is inserted into the shaft holding groove 2a, the shaft holding groove 2a
Each of the shafts 8 in a simultaneously has its protruding rod 10
are ejected from the insert plate 1 and supplied to the mold 11 provided on the other side of the insert plate 1, respectively.
It fits into the fitting hole 11a of No. 1 and is held. Thereafter, for example, a synthetic resin material is poured into the mold 11 to form a molded product in which the shaft 8 is embedded.

As mentioned above, the shaft supply structure devised by this invention is
An automatic shaft insert molding device includes an insert plate having a shaft feeding passage, a plurality of shaft holding grooves arranged in the axial direction on the outer periphery of the insert plate that rotate in the insert plate, and a plurality of shaft holding grooves arranged in the axial direction between the shaft holding groove and the insert plate. It is characterized by comprising a rotating drum that sequentially holds the shafts sent out from the insert plate, and an ejector rod that is disposed adjacent to the insert plate and reciprocates in the axial direction of the rotating drum to send out the shafts in the shaft holding groove. do.

Therefore, according to this invention, multiple shafts can be fed to the mold at the same time and multiple molded products can be formed at the same time, resulting in extremely high work efficiency and reliable shaft feeding. There are advantages. Furthermore, since a large number of shafts can be stored in the shaft feeding path, there is also the advantage that stable supply of shafts can be achieved.
