Description

An injection device including an automatic release agent injection structure and an injection structure for automatic ejection of injection materials

Various embodiments of the present invention relate to an injection device including an automatic release agent injection structure for automatically injecting a release agent into a mold and an automatic ejection structure for automatically ejecting an injection product from a mold.

In general, injection molding is one of the production methods for molding and producing a product. When the raw material is heated and melted, the injection device supplies the molten raw material to a mold in a compressed form, and then injection molded into a desired shape to obtain an injection product, The molded article is completed through a molding process in which the injected molding is separated from the mold while being changed from a liquid state to a solid state.

In such injection molding, a basic method of molding a molded product of a single material is widely used, and thus, an insert molding method in which insert parts of different materials are inserted into a raw material and molded is widely used.

This injection device can be repeatedly molded after separating the molding from the mold. At this time, if the molding and the mold are not separated smoothly, defects in the molding and damage to the mold itself, which is an expensive equipment, occur. This allows the molded product to be easily separated from the mold.

However, in the conventional injection device, the release agent must be artificially manually applied to the mold using a worker application tool without any additional equipment or device, and this is because the operator manually handles the application of the release agent for each molding operation. Not only does the coating state or time change, but also the fatigue of the operator accumulates over the course of the molding operation, reducing work efficiency. In addition, it is difficult to set work standards as the application of the release body is handled manually, so it is difficult to set work standards and production plans. Difficulties arose in establishing

In addition, in the conventional injection apparatus, when taking out an injection product from a mold after injection molding, a worker manually takes it out or an expensive take-out robot device is used separately.

Therefore, since the conventional injection molding machine has a structure in which the operator manually applies the release material to the mold, the operator's fatigue accumulates and the efficiency of the application operation decreases. In addition, the operator takes out the molded product manually. Since it is a structure in which additional workers accumulate fatigue, there is a disadvantage in that the efficiency of taking out the injection molding product is reduced.
