あった。(Prior art) For example, an insert pin (50) as shown in FIG.
Synthetic resin molded products such as gears with inserts (60
), an insert molding machine is used in which an insert pin is fed into the mold by a robot hand, etc. before the mold is closed, and then the mold is closed and resin is injected around it. However, as the molding speed increases, the time the mold is open gradually becomes shorter.
During this time, it becomes difficult to insert the robot hand between the molds and supply the insert pin, and then to release the robot hand to the outside again, which has the drawback that the molding speed of the injection molding machine is regulated by the operating speed of the robot hand. ,
If the robot hand malfunctions, it may get caught between the molds, potentially damaging the expensive robot hand and the mold.

(11 is the fixed plate of the injection molding machine, (2) is the movable plate,
The fixed side mold (4) is attached to the fixed gt (11) via the die mounting plate (3), and the spacer block (2) is attached to the movable platen (2).
A mold (7) on the movable side is attached via 5) and (6), and this mold (7) has a press-fit pin (8) whose tip is press-fitted into the inside of the molded product (60). It is provided so that it can move forward and backward inside the insertion hole (9) formed in the mold (7). The rear end of this press-fit pin (8) is the press-fit pin operating plate OI.
The press-fit pin operating plate α is supported by cylinders (11) and (11) attached to the outside of the movable platen (2)
As [ is reciprocated, the press-fit pin (8) moves back and forth inside the insertion hole (9). This cylinder (
11), (11) are attached with a sensor (12) for detecting the backward position of the piston, a sensor (13) for detecting the forward position of the piston, and a sensor (14) for detecting the intermediate forward position of the piston. ing. Further, an insert pin supply groove (15) whose lower end communicates with the insertion hole (9) of the press-fit pin (8) is formed inside the mold (7). The insert pin supply groove (15) is formed flat so that the posture of the insert pin (50) fed one or more insert pins (50) one by one through the air hose (16) can be regulated in parallel to the insertion hole (9). In addition, insert pin (5
0) is supplied from the parts feeder (17),
(18) is a feed abnormality detection sensor, (19) is an escape cylinder, (20) is an air pressure feed pipe, and (21) is a feed confirmation sensor. The insert pin (50) supplied from the parts feeder (17) is inserted into the escape cylinder (1
9), and the required number of pieces are fed out in accordance with the timing of operation of the injection molding machine, and the air pressure feeding vibrator (2
The insert pin is introduced into the insert pin supply groove (15) via the air hose (16) by air pressure from the insert pin supply groove (15). In addition, the mold (7) has an ejector pin (21
), an ejector plate (22) that supports the ejector plate (22), a spring (23) that supports the ejector plate (22) in the retreated position, and an ejector pin (24) are attached.
When the extrusion piston (25) of the movable platen (2) advances, the ejector pin (21) extrudes the molded product (60), but this part is no different from conventionally known structures.

0) with a hole approximately equal to the outer diameter of the insert pin (50). While the press-fit pin (8) is moving forward in this way, the insert pin (50) is supplied to the upper end of the insert pin supply groove (15) via the air hose (16), and the insert pin (50) is press-fitted as shown in the figure. It falls onto the top surface of pin (8). When the cylinder (11) is moved back and the press-fit pin (8) is pulled out from the molded product (60) when, for example, 0.5 seconds have elapsed after the completion of injection, a hole will be formed in the molded product (60). At the same time, the insert pin (50) that was on the top surface of the press-fit pin (8) falls into the insertion hole (9). Next, when the cylinder (11) is advanced again to the intermediate position under the control of the sensor (14), The insert pin (50) is pushed by the tip of the press-fit pin (8), moves forward toward the molded product (60), and is inserted into the molded product (60). Press-fit pin (
The diameter of the hole in the molded product (60) decreases due to resin contraction between the time when the insert pin (5o) is pulled out and the insert pin (5o) is inserted.
) is securely held inside the hole, and insert molding is completed. After that, open the mold (7) and ejector pin (2).
The molded product may be discharged according to 1). In the illustrated embodiment, the insert pins (50) are press-fitted one by one into the molded product (60), but it goes without saying that a large number of insert pins can be press-fitted at the same time.

ものがある。(Effects of the Invention) As is clear from the above description, the present invention is for inserting an insert pin into a molded product using a press-fit pin from an insert pin supply groove provided inside a mold, so it is not possible to insert the insert pin into a molded product as in the conventional method. Unlike the method of feeding insert pins from the open plane side of the mold, it is possible to feed the insert pins at any speed that corresponds to the molding speed of the injection molding machine, and the feeding device can be inserted between the molds. There is no risk of being caught. Therefore, the present invention makes an extremely large contribution to the industry as an insert molding machine that solves the conventional problems.
