JPH04122470U - Jig for inserting nuts, pins, etc. into the mold during injection molding - Google Patents

Abstract

(57) [Summary] (with amendments) [Purpose] To obtain a jig that allows metal fittings such as small nuts and pins to be easily and quickly inserted into predetermined positions in a mold during injection molding. [Structure] The base of the elongated hollow body with the tip bent is used as the handle 2, and when the operating knob exposed on the handle 2 is pressed, the foremost of the metal fittings 8 stored in the bent tip is sent out. A pushing wire body is passed through a flexible shaft 10 housed in a hollow part of a hollow main body, its base end is fixed to the operation knob, and a pushing projection is fixed to the tip exposed from the tip of the flexible shaft 10.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention focuses on nuts, pins, and other metal fittings that are set in the mold during injection molding. This relates to a jig for inserting metal parts into predetermined positions in molds.

0002

[Conventional technology]

Traditionally, this type of work involved inserting the mold into the mold using a person's fingertips, which was very time-consuming and labor-intensive. The drawbacks were that it was time consuming, complicated, and did not improve efficiency.

0003

[Problem that the idea aims to solve]

The challenge with the design was to quickly and quickly insert relatively small metal fittings such as nuts and pins into the mold. An object of the present invention is to provide an insertion jig that can be easily installed.

0004

[Means to solve the problem]

The means of the present invention has a right-angled bent portion at the tip and a handle integrally provided at the base. A through hole is formed in the elongated main body from the tip of the handle to the right-angled bent part, and the through hole is inserted into the grip. The coil spring is housed in the large diameter hole near the hand, and the open end of the right-angled bend is covered with metal such as a nut. A flexible shaft is inserted between the large diameter hole and the expanded hole, and the handle is The slider integrated with the operating knob incorporated in the handle is housed in the recessed space of the handle, and the coil The base of the pushing wire body, on which the pressing collar of the spring is protruding, is fixed to the slider, and the tip of the pushing wire body is fixed to the slider. The end passed through the flexible shaft and fixed the metal fittings inside the expanded hole to the extruded protrusion. There is a particular thing.

[0005]

[Effect]

When you hold the handle part 2 and press the operating knob 12 with your thumb, the coil spring 6 is compressed and the same Since the extrusion wire body 15 is sometimes pushed, it is stuffed into the expanded hole 9 by the extrusion protrusion 21. Push the metal fitting 8 from the rear end to insert and set the most advanced metal fitting 8 into a predetermined position in the mold. . After that, if you release your thumb, the coil spring 6 will cause the operating knob 12 and the pushing wire body 15 to return to their original positions. is returned to the position.

【Example】

In the figure, 1 is an elongated main body, and along the longitudinal direction there are two left and right components 1a, 1. It is divided into b. This main body 1 has a slightly thick handle part 2 integrally formed at the base, A slightly narrower right-angled bent portion 3 is provided at the front end. From the tip of the handle part 2 to the tip of the right-angled bent part 3 A through hole 4 is opened at Insert the accommodated thin tube 7 and attach a metal fitting 8 such as a nut or pin to the open end of the right-angled bent portion 3. A flexible cable is provided in the through hole 4 between the large diameter hole 5 and the enlarged hole 9, in which an enlarged hole 9 for storage is provided. The shaft 10 is inserted and one end thereof is inserted into the thin tube 7. A slider 13 protrudes below the operating knob 12 into a recessed space 11 formed in the handle portion 2. pay. The slider 13 has a neck portion 13a, which is the narrow portion 11 of the recessed cavity 11. Enter a. The operating knob 12 is exposed on the surface of the handle portion 2, and the coil spring The thick base 15a of the pushing wire body 15 having the pressing collar 14 of 6 is connected to the pore 1 of the slider 13. 7 and fix the pushing wire body 15 to the slider 13 with the screw 18, and the pressing collar 14 is fixed to the slider 13 with the screw 18. It is in contact with one end of the spring 6 and is received by a cap 16 fitted on the thin tube 7, and the base of the pushing wire body 15 is The part 15a is made to pass through the cap 16, and the tip of the pushing wire body 15 is made of a flexible material. A pusher that penetrates the inside of the bull shaft 10 and presses a plurality of metal fittings 8 inserted into the expanded hole 9. The protrusion 21 is fixed, and the metal fittings 8 located at the opening end are lightly fastened to the right-angled bent portion 3. A fall prevention spring pin 20 is attached.

[0007]

[Effect of the idea]

According to the present invention, when the operating knob 12 is pressed with the thumb, the pushing wire body 15 is moved to the coil spring 6. The metal fittings 8 are pushed by the extrusion protrusion 21, so the first one is pushed out. Nuts and pins can be placed accurately and quickly in the mold. Metal fittings such as rings can be set inside the mold, significantly improving work efficiency.
