Description

A double injection molding system

The present invention relates to a dual injection system. More particularly, the present invention relates to a dual injection system, in which each process is optimally performed corresponding to the external shape and color characteristics of an automotive suspension bearing (MSBU) The present invention relates to a dual injection system capable of dramatically shortening a process cycle, minimizing a defect rate, and maximizing work productivity.

Insert injection is a mold injection method in which a metal insert is inserted into an injection mold and injection molded to mold an insert made of a metal into an integral part of a resin material, In a single cycle.

Especially, as the demand for improving the appearance quality is increased, double injection which is made of different colors and materials and can improve the appearance quality is widely used. Such a double injection method includes an insert method, a rotary method, a turntable method, , And a stain-foam method.

However, among the above-mentioned conventional double injection methods, the turntable method, the index core rotation method, and the stainless-foam type double injection are configured in such a manner that the primary injection-molded article is secondarily injected by rotating the mold or core after the primary injection is performed The mold structure is complicated, and the manufacturing process is disadvantageously increased.

Accordingly, there is a growing interest in a double injection method by robot transfer in which a primary injection molded article molded by a primary injection mold apparatus is supplied to a secondary injection mold apparatus using a robot transfer apparatus.

In the conventional double injection molding by robot transfer, first, a first aligning step of stacking and aligning the supplied inserts, and a first injection molding by inserting the aligned inserts into a cavity of the first injection mold apparatus A second aligning step of aligning the first injection molded article subjected to the cooling step, a second aligning step of aligning the first injection molded article subjected to the cooling step, and a second aligning step of aligning the first injection molded article, A second mold injection step of inserting the first injection molded article aligned by the process into the cavity of the second injection mold apparatus to perform the second injection molding; And a vision inspection process for performing vision inspection. Wherein the aligning step is defined as a step of aligning the insert or the first injection-molded article to form a predetermined position and orientation when the insert or the first injection-molded article is inserted into the cavity of the injection mold apparatus.

In addition, the conventional dual injection molding by robot transfer is configured to transfer the process objects, which have been subjected to the respective processes, to a next process using a servo robot, which is an end-effector equipped with a chucking unit and a transfer means, And the process time can be shortened.

However, in the conventional double injection molding by robot transfer, there are a stacking process in which a large number of supplied inserts are stacked and loaded, an aligning process of aligning the stacked inserts in a predetermined position and direction, Since the transfer process for transferring the servo robot to the preset position where the chucking of the servo robot is performed is performed by the human force, unnecessary labor is consumed, the process time is delayed, the accuracy of alignment is lost, It has disadvantages that frequent accidents occur.

In addition, the conventional double injection molding by robot transfer involves a cooling step of cooling the first injection molded article, a transfer step of transferring the first injection molded article subjected to the cooling step to a position where chucking of the server robot of the second injection mold apparatus is performed Is separately operated and is performed by the human power, the process cycle is increased and unnecessary labor is consumed.

In other words, the conventional double injection molding by robot transfer has a disadvantage in that the process cycle is excessively high because each process is separately performed and thus the process is not continuously performed.

In other words, although the research on the mold apparatus for the double injection has progressed considerably, research on the double injection system for automating the entire process is insufficient, and accordingly, all processes from the time of receiving the insert to the execution of the vision inspection There is increasing interest in an automatically operated dual injection system.
