Description

Injection molding fixture jig cleaner {A FIXING JIG WASHING DEVICE FOR FORMER}

The present invention relates to a jig cleaner, and more particularly, to a washing machine used to wash the plating material remaining in the jig after the injection for silver plating is fixed, such as a mobile phone case.

In general, with the development of communication technology, the spread of mobile phones, which are mobile communication terminals, is rapidly spreading.

On the other hand, these mobile phones inevitably generate electromagnetic waves because they use a strong high frequency circuit of about 900MHz and a plastic case to reduce the weight.These electromagnetic waves are in addition to simple physical effects such as headache or nerve stimulation. Exposure to electromagnetic waves for a long time is known to adversely affect the human body, such as leukemia, lymph cancer, brain cancer, cancer of the central nervous system, breast cancer, dementia, miscarriage and malformation.

Therefore, as a method for shielding such electromagnetic waves, in recent years, silver plating is applied to a mobile phone case which is an injection molding using a method such as spraying in the manufacturing process of a product.

In the process of silver plating, silver plating is carried out while the cell phone case made by molding is temporarily fixed to a separate fixing jig, and when such plating is completed, the case is separated from the fixing jig and then assembled. The process is progressed, the fixing jig was used to wash the silver powder buried during the plating operation and then to fix the new case again to perform the silver plating operation repeatedly.

However, in the related art of washing the fixing jig, after filling the washing water in the washing tank to a certain level, the fixing jig was immersed for a predetermined time and then taken out again, so that the effective washing was not performed. As the fixing jig is reused in the state where the silver powder is not completely washed, there is a problem that the defect rate during silver plating is increased.

The present invention is proposed to improve the above problems in the prior art, it is possible to reduce the efficiency of the work and the occurrence of product defect rate by making the cleaning work of the fixing jig used in the silver plating process of the injection molding more efficient The purpose is to.

In addition, on both fixing members (11a, 11b), the release preventing piece (12 ') for preventing the separation of the fixing jig (1) inserted into the insertion groove 12 is supported elastically to enable the sliding flow.

In addition, in the washing tank 10, two rows of supply pipes 16, in which a plurality of nozzle holes 16 'are formed to spray washing water at high pressure from both sides at the same time, are provided in two rows. The wash water sprayed through the 16 ') flows through the drain 19 of the lower portion of the washing tank 10, and the washing water reservoir 20 is configured. The washing water was diluted by mixing weak alkaline or neutral wash stock solution at a rate of 4 L per 100 L of water.

In addition, the drain 19 is mounted to detachable filter net 21 for filtering the powder and foreign matter, such as silver powder contained in the washing water flowing down, and is stored on one side of the wash water reservoir 20 A driving pump 22 for forcibly transferring the washing water to the nozzle pipe 16 is installed.

On the other hand, the heating unit for heating the wash water stored in the wash water storage 20 to a predetermined temperature is configured at the bottom, the heating unit and the heating oil storage unit 25 is filled with a heat medium oil having excellent thermal stability and oxidation stability The heater rod 26 is inserted into the heating oil storage unit 25 to dissipate heat, and the power supply unit 27 supplies power for the heat generation of the heater rod 26, thereby indirect heating to the washing water. It could be done.

In the figure, reference numeral 30 denotes an upper cover, and 31 denotes a mouthpiece for detecting the level of the washing water.

The working effect of the operation of the jig cleaning device of the present invention having such a configuration will be described.

After opening and opening the upper cover 30, the fixing jig 1, which was used for silver plating of the mobile phone case, is installed in the washing tank 10. At this time, in inserting the handles 2 on both sides of the fixing jig 1 into the respective insertion grooves 12 of the fixing fixtures 11a and 11b, the insertion preventing pieces 12 'are pushed in so as to allow insertion. When the release prevention piece (12 ') is completed when it is released to the original position by the elasticity is prevented the separation of the fixing jig (1) is achieved by a fixed state by both fixing (11a, 11b).

In this state, when the upper cover 30 is closed and the power is applied, the washing water stored in the washing water reservoir 20 is supplied at a high pressure through the supply pipe 16 as the driving pump 22 is operated.
