Description

Technical Field [0001] The present invention relates to an injection molding machine,

The present invention relates to an injection molding machine which can be easily connected to a cooling water of an injection molding machine or a one-touch nipple which is connected to an end of a hose which is a connecting medium between an air automation device and an air compressor, Quot; one-touch nipple ", which allows air (air) from a hose to quickly leak.

An injection molding machine is an apparatus for producing a desired type of product by injecting a synthetic resin solution in a molten state into a cavity of a mold while cooling and opening a mold, taking out a molded product after cooling, and producing a desired product.

1, the mold constituting the injection molding machine 2 is composed of a stationary mold 6 coupled to the stationary plate 4 and a movable mold 7 coupled to the movable plate 5, Opening and closing operations are performed between the stationary mold 6 and the movable mold 7 by the sliding movement of the movable plate 5. [

One of the conditions for producing high-quality articles in an injection molding machine is to cool the resin liquid injected into the mold to an appropriate temperature depending on the situation.

Accordingly, the cooling water flows around the cavities around which the resin liquid is injected, so that the both ends (inlet and outlet) of the cooling water are connected to the cooling water tank (not shown) So that the cooling water flows smoothly into the mold.

Meanwhile, the stationary mold 6 and the movable mold 7 constituting the injection molding machine are detachably attached to the stationary plate 4 and the movable plate 5, respectively. This is because the molds (fixed and movable molds) So that various types of products can be produced.

When the mold is replaced, the valve provided for the hose 10 connected to both ends (inlet and outlet) of the mold is blocked by the cooling water of the mold to stop the flow of the cooling water. Then, the hoses 10 are separated from the inlet and outlet, The mold 6 and the movable mold 7 are separated from the fixed plate 4 and the movable plate 5. [

However, due to the fluctuation of the mold during the separation process, the cooling water existing inside the mold with the cooling water of the mold flows out to the inside of the injection molding machine, causing contamination and rust to the expensive injection molding machine.

On the other hand, there have been many proposals on the prior literature for the purpose of preventing leakage of cooling water supplied to the molds by means of technical means for closely sealing the inlet and outlet to the cooling water.

For example, Korean Patent No. 10-1158727 entitled " Mold Cooling Water Stopper ", Korean Patent Laid-Open No. 10-2006-0133879 " Cooling Water Leakage Prevention Device for Mold ", and Korean Registered Utility Model No. 20-0276520 " ".

The above-mentioned prior art documents constitute a stopper for tightly closing an inlet and an outlet of the cooling water, and the stopper is formed by screwing or by fitting a stopper, .

However, the stoppers provided in the above documents are not a technique for preventing the outflow of the cooling water existing in the injection molding machine to be replaced when the injection molding machine is replaced. Instead of the technology for preventing the cooling water from leaking due to the pressure of the cooling water during the operation of the mold, To close and close tightly.

That is, the purpose of the plug is not to circulate the cooling water through the connection with the cooling water tank separately formed outside, but to shut the end with the cooling water of the mold so as to prevent the leakage of the cooling water And has a somewhat complicated configuration in terms of its configuration.

However, as shown in the photographs of FIGS. 1 and 2, the molds 6 and 7 are configured such that the cooling water is smoothly circulated to the inside of the mold in order to maintain the proper temperature. To this end, the Nipple And the one-touch nipple 12 is connected to a cooling water tank (not shown) that is separately configured by coupling the hose 10 to the one-touch nipple 12.

2, the one-touch nipple 12 is tightly coupled to the inlet and outlet of the molds 6 and 7 by screwing. The one-touch nipple 12 is semi- .

Accordingly, when the mold is changed from the injection molding machine, the hose 10 connected to the one-touch nipple 12 is first removed. After the hose is removed, the end of the nipple 12 is closed so that the cooling water existing in the mold does not flow down However, up to now, it has been neglected in efforts to prevent the end of the one-touch nipple 12 from being lightly considered for the water flowing down from the inside of the mold when the mold is replaced.

Accordingly, when the mold is replaced, there is a problem that the cooling water flows down into the injection molding machine, thereby exposing the equipment to malfunction and internal contamination and corrosion.

In addition, the one-touch nipple 12 is usefully combined with an air automation device that operates on the basis of an air compressor in addition to the end of the mold as cooling water. That is, the one-touch nipple 12, which is coupled to the end of the mold described above, is used for smooth connection and disconnection between the air compressor and the bar hose connected to the air compressor through the hose.

In addition, the air automation equipment also removes the hose connected to the air compressor according to various situations such as the replacement of the equipment. At this time, the one-touch nipple is connected to the end of the hose disconnected from the automation equipment. It would be good if the one-touch nipple could be quickly closed to prevent air from leaking.

As described above, up to now, a method for preventing the opening of the nipple from being opened with respect to the one-touch nipple has not been seriously discussed.

Korean Patent No. 10-1158727 " Mold coolant plug " Korean Patent Laid-Open No. 10-2006-0133879 entitled " Korean Registered Utility Model No. 20-0276520 " Cooling water leakage preventing device for mold "

Therefore, the present invention provides a method for preventing a hole of a one-touch nipple which is opened to the one end of the mold as cooling water of the mold or the one-touch nipple which is connected between the air compressor and the end of the hose, And a stopper for a one-touch nipple that can quickly prevent leakage of cooling water from the device and leakage of air from the automation device.
