Abstract

PURPOSE:To arrange so that work may be inserted automatically even when a work cannot be inserted through an insertion hole as it is chucked by inserting a work into an insertion hole of a die as it is held between an ejector pin and a pressing rod of a work pressing device. CONSTITUTION:A work 3 is grasped by closing a chuck 4, 4 mounted on a carrier 20. Then it is moved on a die 1 and at the same time, is caused to descend. Then the carrier 20 is positioned by fitting a bush 15 into a guide pin 2 on the die 1. In other words, a work 3 is positioned by so doing. If a stopper 12 is caused to descend, a pressing rod 6 is prevented by a guide 14 from tilting sideways and comes down correctly along an axial center. Then the work 3 is pressed by the force of a spring 13 against an ejector pin 7. Following this procedure, the work 3 is released from the chuck 4, 4 opened and the ejector pin 7 descends along an insertion hole 11 and the work 3 is inserted into the insertion hole 11 without falling down, while the pressing rod 6 falls down while pressing the work 3 by the spring 13.

子る。The push rod (6) is prevented from tilting in the lateral direction by the guide (21), descends precisely along the axis, and the workpiece (3) is moved into the ejector turbine ('y)vc by the force of the spring (13). On the other hand, in the pressing state, the chuck force of the chuck (4) (4) on the workpiece (3) is the downward force of the workpiece (3) due to the downward force of the push rod (6) caused by the spring (13). If it is not strong enough to restrict movement and there is a gap between the lower end of the workpiece (3) and the upper end of the ejector turbine ('7), the ejector turbine (2) may come into contact with the workpiece (3). Move the child downwards.

することができる。(Effects of the Invention) In the method of the present invention, the VC for inserting the workpiece into the mold is between the ejector turbine for ejecting the injection molded product from the cavity and the device for pressing the workpiece provided above the ejector turbine. Since the workpiece is inserted into the mold by the VC while being held between the chucks, the workpiece can be inserted accurately, and the workpiece can also be inserted into the mold while being held by the chuck as in the conventional method. Even if there is no special space or the workpiece has a shape that cannot be inserted into the insertion hole of the folding die in which the workpiece is chucked, it can be easily inserted.

したがってその挿入操作ハ榎めて容易Ｖこ円滑に行うこ

の作業の効率を揚げることができる。However, the device of the present invention is equipped with a chuck that can be opened and closed at the appropriate time for the workpiece, and the workpiece is pressed by a push rod that constantly moves the mounting downward through a spring. It can be driven upwards against the downward force. As a result, the clamping force between the ejector turbine and the push rod against the workpiece is always appropriate, and even if the chuck is opened during operation, the workpiece can be accurately gripped and inserted into the insertion hole J. After insertion, the push rod simply needs to be lifted upward against the spring, so the operation is extremely easy and the efficiency of the operation can be increased.

[(Example) What is shown in drawing c5 is another example, in which chuck (4) and chuck ← for one workpiece (3)
The two ejector turbines (1) are provided below the chuck (4) to ensure secure insertion.

At this time, the chuck force of the chuck (4W) is
A force capable of correcting a minute misalignment of the axis of the ejector turbine (2012) is sufficient. Therefore, this can be inserted into sulfur with the minute misalignment of the axis corrected. (Effect of the invention) In the method of the present invention, in order to insert the workpiece into the mold,
The workpiece is inserted between the ejector turbine and the device above which the injection molded product is to be ejected from the cavity, and the workpiece is then inserted into the mold. In addition to being accurate, it can also be used in cases where there is no special space for inserting the workpiece into the mold while holding it with a chuck, or where it is impossible to insert the workpiece into the insertion hole of the mold while it is chucked. Even if the workpiece has a certain shape, it can be easily inserted. Also, since the workpiece is inserted into the insertion hole of the mold with the ejector turbine protruding, the insertion hole is not filled with air, and the inserted workpiece is pushed out again by the hermetically compressed air in the insertion hole. Never. (Normally, the outer diameter dimensions of the insertion hole and the ejector turbine are made to match.) Furthermore, there is no need to provide a special air bleed hole in the insertion hole or the ejector turbine. (3) The phrase "is" at the end of the fifth line on page 13 is corrected to "FIG. 5 is a vertical cross-sectional side view of another embodiment." (4) Amend Figure 3 of the drawings as shown in the attached sheet, and supplement Figure 5 of the attached sheet. that's all
