Vacuum forming apparatus of quartz object {MANUFACTURING VACUUM MOLDING APPARATUS FOR QUARTZ OBJECT}

The present invention relates to a vacuum forming apparatus of a quartz object, and more particularly, to a vacuum forming apparatus of a quartz object for applying a tensile force to the quartz object heated by the flame to form a quartz object.

In general, vacuum molding is a method in which the edge of a molding is pressed into a lower mold by a clamp and heated by a heater at the top to draw air from the mold when the molding is sufficiently softened.

The molding method is mainly suitable for making a thin molded article, and in recent years, a molding operation is performed in a vacuum state to suppress bubbles in the molded article.

Patent document 1 relates to a vacuum forming apparatus, referring to this, a vacuum tank having a vacuum inside, a heater for dissipating heat in the vacuum tank, a moving member installed in the vacuum tank and moving the heater, heaters It consists of a mold which shape | molds the molten material arrange | positioned in between and inject | poured inside with the outer surface closely contacted with a heater.

Here, the mold is moved to the moving member so that the mold is positioned between heaters installed in the vacuum tank.

Then, both sides of the mold are in close contact with the heater, and the vacuum tank is sealed in such a state so that the inside of the vacuum tank maintains a vacuum state.

In this case, the mold is disposed on the base plate and disposed between the heaters.

Thereafter, the molten thermosetting resin is injected into each of the molds, and heat is transferred to the heaters to heat the molds, whereby the resins injected into the molds are cured to form a molding according to the shape of the molds.

However, the vacuum molding apparatus as in Patent Document 1 has the following problems.

First, when the molten material is injected into the mold or the molded product is released from the mold, the mold is repeatedly moved to the outside of the vacuum tank and the outside, thereby delaying the work time and the troublesome work.

Secondly, the molten material injected into the mold must be separately generated, and the molten material located at the center of the mold hardens relatively slower than the molten material on the outer peripheral surface portion close to the heater by being in close contact with the mold inner peripheral surface, thereby preventing the internal and external hardenability of the molding. There is this inconsistent problem.

Thirdly, the mold cooled outside the vacuum tank is reheated with a heater in the vacuum tank to take a long time to reach the softening point of the molten material, and accordingly, it takes a long time to harden the molding, and the molten material receives the heat of the heater through the mold, which leads to thermal efficiency. There is a problem that the degradation is lowered production efficiency and consumer reliability at the same time.
