Description

[0001] Injection mold loading system [0002]

The present invention relates to a mold injection molding system, and more particularly, to a mold injection molding system that can easily and quickly load a ring-shaped injection molding tool, and simultaneously extract molded articles from a loading position. And more particularly, to a mold injection system capable of saving a large amount of injection products while minimizing space consumption.

The injection molding is an injection molding method for producing at least one or more materials integrally by injecting a material melted at a high pressure into a cavity of an injection mold apparatus and injection molding the injection mold according to the shape of the cavity, The injection molding is carried out in a manner of filling and injection molding. Therefore, the production time is short and it is suitable for the production and has the advantage of obtaining a product having high mechanical properties. And is widely used.

In particular, with the development of robotic technology, product precision and high performance required, an injection automation system using a servo robot and an end effector has been introduced. Such an injection automation system is designed to meet the precision and high performance of a product But also unnecessary labor and process time can be reduced.

Typically, injection-molded products, which are injection-molded by such an injection automation system, are loaded onto trucks and then transported to a requesting company. Accordingly, prior to loading into the transportation means, work should be carried out to arrange the injection products produced by the mold injection in a manner suitable for transportation.

That is, in the injection automation system, it is possible to perform various processes such as a process of melting the supplied material, a process of injecting the molten resin into the cavity of the injection mold apparatus, an injection molding process, a process of extracting the molded object from the cavity, Although there are various studies on the automation line of each process, there is almost no research on the process of arranging and loading finished injection molding products finally.

Accordingly, in the related art, the process of arranging and loading the injection molds manufactured through the mold injection is mainly performed by the labor force. However, the work through the labor force increases labor costs and labor costs and has a disadvantage of delaying the process time.

FIG. 1 is a perspective view showing an automatic injection apparatus for an injection molding disclosed in Japanese Patent Application Laid-Open No. 10-2009-0021748 (entitled "Automatic injection apparatus for injection molding products").

1 is a block diagram illustrating an automatic stacking apparatus (hereinafter, referred to as a conventional art) 100 of the present invention. The automatic stacking apparatus 100 includes a holding unit 120 capable of holding or releasing an injection product 190, a conveying unit 120 for horizontally or vertically conveying the holding unit 120 130 and a loading box feeder 140 for feeding the loading box 141 on which the injection products 190 are to be loaded.

In the prior art 100, when the injection object 190 is held by the holding part 120, the holding part moves horizontally or vertically by the transfer part 130 to load the held injection object 190. It is possible to automatically load the articles 190 on the loading box 141 without separately arranging them.

However, in the conventional art 100, because the mounting grooves 142 are formed on one side of the loading box 141, the loading slots 142 corresponding to the size and shape of the injection molding 190 141 must be manufactured separately, which increases manufacturing cost and complicates the process.

In addition, as in the conventional art 100, a method of loading an injection object using a separate loading box 141 is a problem in that the loading efficiency of the loading object 141 is considerably reduced due to an increase in unnecessary space consumption due to the loading volume of the loading box 141 Lt; / RTI >

In addition, since the conventional art 100 is configured such that the injection products 190 are stacked one by one in the mounting grooves 142, they are useful for injection products having a predetermined volume and area. However, when applied to injection products having a small volume, And the efficiency is deteriorated.

The conventional bearing cage 200 configured as described above forms a hollow disk or a circular ring shape when viewed in a plan view.

Assuming that such a conventional bearing cage 200 is injection-molded, the prior art 100 of FIG. 1 is not suitable for a small-volume bearing cage 200, and in detail, And the efficiency drops off.

In other words, it is urgent to study a loading system which is manufactured in correspondence with the size, weight and shape of the bearing cage 200 and which can maximize the loading efficiency while automatically loading the finished injection product.
