Abstract

(57) [Summary] [Purpose] A mold used in the die-casting method,
It is a mold release agent application device by a small robot for the purpose of applying a release agent in a necessary amount to a required place so that release from a product can be efficiently performed. [Structure] An extension shaft 2 is provided and fixed to an arm portion of a small robot 1 having a multi-joint function, and angle conversion mechanisms 3 and 3'for changing the angle of one side from the extension shaft 2 are provided, and a nozzle 5,
The nozzle distributor 4 with 5'is attached to one side of the angle conversion mechanism 3 or 3 '. With such a structure, each mechanism is manually converted to a position required for mold release so that the nozzle 5 or 5'is predetermined. No. 5, the nozzle 5 is connected to the memory circuit of each control panel by a pipe from the release agent dilution pressure feeding device provided externally,
A spray system control board is installed so that it can be pressure-fed to 5 ', and the amount of mold release agent is automatically sprayed from the nozzles 5 and 5'on a required amount for mold release every time. It is characterized by

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is to inject a molten metal into a die-casting die, and after cooling, release a releasing agent efficiently and in a necessary direction in order to release from the die. The present invention relates to a mold release agent application device for applying only a necessary amount.

[0002]

2. Description of the Related Art Conventionally, in order to separate a mold of a die casting machine from a product, a mold release agent is sprayed on the entire surface of the mold surface, which is required for mold release, by a coating machine having a large number of nozzles. Spraying was done by an automatic machine that sprays it by hand or by hand.

[0003]

However, in the conventional automatic coating method, since the entire surface is sprayed and coated by the nozzles of a large number of pipes, even unnecessary surfaces are coated with a large amount of release agent, which is necessary. There is a problem in that the surface is not necessarily applied, and when the entire surface is applied by a single jet, a large amount of compressed air is ejected, which causes noise and the surrounding atmosphere becomes dirty.

[0004]

The present invention provides a robot body 1
The extension shaft 2 is combined and fixed from the arm part of the robot, the angle conversion mechanisms 3 and 3'are provided at the tip of the arm, the nozzle distributor 4 is provided through the angle conversion mechanism 3, and the plurality of nozzles 5 and 5'are provided at the tip. A storage circuit built in the spray system control board so that the spray system control board 10 in which a main body and an electric control circuit are combined can control the spray of a required amount of the release agent in a predetermined direction. The operation of each mechanism is automatically controlled by the control system of the die cast machine control panel 14, the release agent dilution pressure feeding device 6, and the unloader control panel 16 by inputting the operation into the memory. It is linked.

[0005]

According to the present invention, the spray system control board 10 is combined with the robot main body 1 so that the spray nozzle is directed to a required mold surface in order to apply the mold release agent to the mold.
The memory setting input is input so that the mechanism that changes the application direction and the application amount to the electric memory circuit can be operated in conjunction, and each mechanism and joint automatically operate in the predetermined direction and are released from the mold. Apply the agent.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below. FIG. 1 is a perspective view of a part of a mold releasing agent coating apparatus according to one embodiment of the present invention. The extension shaft 2 fixed to the arm of the robot body 1 on which the rotation mechanism is mounted
Therefore, the angle conversion mechanisms 3 and 3 ′ whose angles can be changed in the direction of the − side are provided, and the nozzle distributor 4 having the nozzles 5 and 5 ′ is mounted on the moving surface of the angle conversion mechanism 3 ′ and separated. The joints of the respective mechanisms are set at the locations required for the mold, and the electric storage circuit of the spray system control panel 10 is made to store and input together with the necessary amount of the release agent spray sent from the release agent dilution pressure feeding device 6, Each time, the release agent is automatically spray-applied on the required surface of the mold in the required amount.

[0007]

As described above, according to the present invention, since (a) the mold release agent is applied only to the portion that needs to be released from the mold, the mold release agent does not adhere to an extra portion, and for this reason (B) The release agent is applied only on the necessary parts, so the consumption of the release agent is reduced, and the spray can be applied with the minimum required injection amount, so there is less external scattering and environmental purification. (C) The injection with compressed air for spray-coating the release agent is effective, and the consumption of compressed air is small because only the necessary parts are injected, compared to the conventional injection with multiple nozzles in all directions. Equipment costs and running costs are reduced.
