Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for automatically inserting a component insert or a component in an injection molding process. The present invention relates to an insert device (loading device) used for performing the above.

[0002]

2. Description of the Related Art For example, an insert part 52 such as a metal fitting shown in FIGS. 5A and 5A and an insert part 53 shown in FIGS. When a resin molded product 51 shown in FIG. 1 is molded, as shown in FIG. 4B, these insert parts 52 and 53 are inserted into a cavity 55 of a mold 54, and then the molding material is filled into the cavity 55 and the resin is filled. At the same time as the molding of 56, insert molding for integrating the resin 56 and the insert components 52 and 53 is performed. The insert parts 52 and 53 are generally made of metal, and a rubber material may be used instead of a resin material as a molding material.

In this type of insert technology, it is necessary to secure an appropriate clearance between the mold 54 and the insert parts 52, 53, and the mold 54 and the insert parts 52, 53 are chamfered. It is common practice to employ means for smoothing the inserts such as. In addition, an RCC device may be used to absorb a displacement between the mold 54 and the insert jig.

[0004] However, the above-described measures cannot be adopted in the insert of a multi-piece small-sized small component. For example, in the case where resin is generated due to restrictions on the product shape and the mold 54, it is often impossible to secure an appropriate clearance or to chamfer the insert parts 52 and 53. In the case of multi-cavity mounting, it is necessary to position each cavity 55. However, since the mounting space is insufficient and it is difficult to use the RCC device, it is not possible to absorb the position error especially for the irregularly shaped parts. It is possible.

[0005]

SUMMARY OF THE INVENTION In view of the above, the present invention can perform high-precision positioning when inserting an insert part into a fixed position of a part insert part.
Accordingly, it is an object of the present invention to provide an insert device capable of preventing damage to a mold or a device due to biting of an insert part and improving the quality of a molded product.
