JPH04130818U - A jig that sets metal pieces, etc. in a specified position in a mold during injection molding. - Google Patents

Abstract

(57) [Summary] [Purpose] To provide a jig that allows small pieces such as metal pieces to be easily and reliably set in a predetermined position in a mold during injection molding. [Structure] The main body of the jig has a receiving hole shaped like a metal piece, etc. that penetrates from the top surface to the bottom surface into which it fits, a guide plate with a guide hole of the same shape as the receiving hole at a different position relative to the receiving hole, and The slide plate is slidably inserted into the gap between the tool body and the guide plate, and has a communicating hole for receiving the lowest piece of the metal pieces stacked in the storage hole. The communication hole is formed in such a position that it coincides with the accommodation hole before sliding, and coincides with the guide hole during sliding, allowing a piece of metal to fall into a predetermined position in the mold through the guide hole. [Effect] Several pieces of metal can be set in a predetermined position in a mold in one operation.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention sets embedded small pieces such as metal pieces at predetermined positions in the mold during injection molding. This relates to jigs used in cases where

0002

[Conventional technology]

Traditionally, these pieces of metal were placed in a specific position in the mold by a single worker. It was time consuming and inefficient.

0003

[Problem that the idea aims to solve]

The problem with this invention is to create a tool that can set several pieces of metal in the specified positions of a mold in one motion. The aim is to provide tools.

0004

[Means to solve the problem]

The means of the present invention are as follows. In other words, the present invention provides a housing hole that penetrates from the top surface to the bottom surface and has a shape into which a metal piece, etc. can fit. A plan in which the jig body and the guide hole, which has the same shape as the accommodation hole, are opened at different positions relative to the accommodation hole. It is slidably inserted into the gap between the inner plate, the jig body, and the guide plate, and is stacked and accommodated in the accommodation hole. It consists of a slide plate with a communication hole into which the lowest piece of metal scrap is inserted. The communication hole of the slide plate aligns with the accommodation hole before sliding, and when sliding, it aligns with the guide hole and forms a piece. Injection molding in which the metal piece is formed in a position where it falls into a predetermined position in the mold through a guide hole. This is a jig that is used to set metal pieces, etc., in a predetermined position in a mold.

[0005]

[Effect]

As shown in FIG. 5, when the metal pieces K are stacked and stored in each accommodation hole 6, the lowest The metal piece K enters the communication hole 8 of the slide plate 3. In this state, move the slide plate 3 as indicated by the arrow in Figure 6. When sliding in the direction, the communication hole 8 matches the guide hole 7, and the metal piece K in the communication hole 8 falls out. It is lowered and set in place in the mold.

【Example】

In Figures 1 to 4, numeral 1 is the jig main body, 2 is a guide plate, and 3 is a slide plate. . The jig body 1 consists of a thick light metal plate formed into a rectangular shape, and the A recessed step is formed on the surface, a metal guide plate 2 is applied, and the slide plate 3 is moved by the recessed step. A slit 4 passing through the jig is formed, and the jig body 1 is fixed to the jig body 1 with screws 5. Slide plate 3 is It is passed through the gap 4 formed by the recessed step formed along the longitudinal direction of the jig main body 1. The jig body 1 and the guide plate 2 have metal pieces K set in the mold at different positions. In the figure, there are four accommodation holes 6 and guide holes 7 that fit into each other. jig body 1 The accommodation hole 6 penetrates from the top surface to the bottom surface, and the guide hole 7 of the guide plate 3 is located below it in a staggered manner. do. The slide plate 3 has communication holes 8 that match and have the same shape as each accommodation hole 6, and overlaps each accommodation hole 6. The lowest piece of the metal piece K that has been folded in is inserted. Then slide the slide plate 3 When this happens, move only the metal piece K that has entered the communication hole 8, and slide the other metal pieces. The metal piece K in the communication hole 8 reaches the position of the guide hole 7 of the guide plate 2 and falls. Perform the operation of setting the lower mold at a predetermined position. In addition, 9 in the figure is the jig body and guide plate. A long hole 10 formed in the slide plate 3 is inserted with a stop pin inserted through the hole 2. The slide plate 3 slides within that range, and the communication hole 8 matches the accommodation hole 6 of the jig main body 1. The guide plate 3 is configured to reciprocate at a position that coincides with the guide hole 7 of the guide plate 3. Reference numeral 11 indicates an operation knob fixed to the slide plate 3. Also, Figure 7 shows the composite of metal pieces K together. This shows the injection molding completed state embedded in the resin molded body N, and the M portion is removed.

[0007]

[Effect of the idea]

Since the present invention has the configuration described above, the jig main body is stabilized on the mold, and the Simply slide the ride plate to place multiple pieces of metal in place in the mold. Can be set. Therefore, work efficiency is significantly improved, making injection molding extremely efficient. It can be done smoothly.
