JPH05154585A - Simple crimping tool to metal die - Google Patents

Abstract

PURPOSE:To provide a safe and simple crimping tool to a metal die which need not remove the die from a press, takes a short time for one crimping including a preparation time, and has high productivity. CONSTITUTION:This device is a crimping tool to blow glass beads B on the surface of the metal die 1 to perform crimping, and composed of a cover 2 with which the metal die 1 is covered, an air gun 3 having a glass beads suction hole 3b on the flank and a nozzle 30 opened in the cover 2, a glass beads tank 4 provided with a supply tube 4a which supplies the glass beads B to the air gun 3, a hose 5 to discharge the glass beads B blown on the surface of the metal die 1 and the air from the cover 2 and a glass beads storing tank 6 to separate the glass beads B guided by the hose 5 from the air and to store the glass beads.

Description

Detailed Description of the Invention

[0001]

[Industrial application] The surface of a mold is textured in order to impart a texture pattern to the surface of a molded product. The present invention relates to a simple embossing tool for the die.

[0002]

2. Description of the Related Art A description will be given with reference to FIG. Conventionally, when the mold 1 is repeatedly pressed and molded (about 400 shots) and the mold 1 is worn, the mold is removed from the press (not shown), placed in the dry forming device 12, and air is blown from the bottom of the glass bead storage tank 13. , And the glass beads B are sprayed on the surface of the mold 1 together with air to give a grain (about once every four days). Meanwhile, during that time, the spraying is sometimes stopped to check the texture.

However, in order to remove the worn mold from the press, put it in the dry forming device 12, spray the glass beads B to give a grain, and then attach it again to the press to raise the temperature and return it to a moldable state. It takes about one hour, and the shortening is required to improve productivity.

[0004]

The problem to be solved is that it takes a considerable amount of time and time to re-texture the surface of a conventional worn mold.

[0005]

Means for Solving the Problems An explanation will be given with reference to FIG. The present invention is an embossing tool for spraying glass beads B on the surface of a mold 1 to give a grain, which is a cover 2 that covers the die 1, and a nozzle 3a is attached to the inside of the cover 2 so that the nozzle 3a is opened. An air gun 3 provided with a glass bead suction port 3b, a glass bead tank 4 provided with a supply pipe 4a for supplying the glass beads B to the air gun 3,
Glass beads B sprayed on the mold surface, a hose 5 for discharging air from the cover 2, and a glass bead reservoir tank 6 for separating the glass beads B guided by the hose 5 from the air and storing the glass beads B. It is a simple embossing tool for the mold.

[0006]

EXAMPLES Examples will be described. 1 is a mold whose surface is abraded, 2 is a cover for covering the mold 1, and 3 is an air gun for spraying glass beads B on the surface of the mold 1. The nozzle 3a is attached so as to open, and the glass bead suction port 3b is provided on the side surface. A glass bead tank 4 supplies the glass beads B to the air gun 3, and a supply pipe 4a is provided between the glass bead tank 4 and the nozzle 3a. Reference numeral 5 is a hose for discharging the glass beads B sprayed on the surface of the mold 1 and the air from the cover 2. 6 is a glass bead storage tank for storing the glass beads B, which is guided by the hose 5
There is a function to separate air and air. 6a is an air discharge port, to which a filter F for filtering the glass beads B is attached.

The operation will be described. With the mold 1 still attached to the press, the cover 2 and the air gun 3 of the simple embossing tool of the present invention are mounted directly on the press 1, and the glass bead suction port 3b and the glass bead tank of the air gun 3 are attached. 4 is connected to the supply pipe 4a. Next, the glass beads B are put in the tank 4, the cover 4 and the glass bead storage tank 6 are connected by the hose 5, and the filter F is attached to the air discharge port 6a. When the air is supplied to the air gun 3 after the above preparations are completed, the glass beads B and the air are ejected from the nozzle 3a, and the wrinkles are formed on the surface of the mold 1.

[0008]

Since the present invention is constructed as described above,
There is no need to remove the mold from the press, and the embossing work is completed in 5 to 10 minutes per time including preparation, and the danger associated with moving the mold is eliminated, and the maintenance work of the mold 1 is performed. It is extremely simplified and the working time is greatly shortened, and the productivity of the molding work is improved.
