The following describes the invention in more detail with reference to the accompanying drawings.

First, as shown in Figs. 1 to 4, the present invention is a frame frame forming a three-stage 100, a first molding frame 200 to be attached to the first base of the frame, and the first of the frame A vacuum pump is formed to induce a vacuum state to the second molding frame 300 to be attached to the second base, the third molding frame 400 to be attached to the third base of the frame, and the vacuum tube formed on the first molding frame. It consists largely of 500.

As shown in FIG. 1, the frame 100 is formed such that the first, second, third bases 110, 120, and 130 are sequentially stacked to form a skeleton tower having a three-stage configuration.

At this time, the frame tower (frame frame) forms a base consisting of each of three layers, each of the base in one direction or the other direction, a general guide bracket, which is a certain plate-shaped or square tube crosses the first molding frame and fixing The cylinder is installed to support the main cylinder to serve as a rigid fixing plate (sieve).

At this time, the guide bracket of the second base of the guide bracket is fixed to be spaced apart so as not to interfere with each other when the pressing molding frame of the first molding die, in particular, the position for fixing the fixed cylinder spaced at regular intervals It is desirable to combine in.

At this time, the vacuum plate of the first molding die, which will be described later, is seated on the upper surface of the first base, and then welded and fixed. In particular, the vacuum plate of the first molding die is formed to be in close vacuum contact with the molding die while maintaining the vacuum state to seal the air.

That is, as an embodiment of the present invention, the guide bracket of the first base corresponding to the lower portion of the molding mold formed like a pot pot has a predetermined through groove formed on the surface, and the lower portion of the molding mold formed like the pot pot is fitted in correspondence. At this time, the outer circumferential surface of the molding die is a separate vacuum plate is welded and coupled to facilitate the primary and hermetic sealing space of the upper and side bars, the molding mold to be seated as if from the top to the bottom is precise vacuum state by separate welding processing It is fixed to the guide bracket while maintaining. A more detailed vacuum promotion method will be described in the first molding mold 200 to be described later.

Forming mold 210 and the forming mold 210 is formed on the outer peripheral surface of the upper end of the upper surface 212 and the through-hole 213 is formed by the upper space 211, and the forming mold 210 Together with the outer circumferential surface and the surface of the first base 110 to form a constant sealed vacuum portion 221, one side of the outer peripheral surface is provided with a separate vacuum control tube 222 is a vacuum plate 220 is formed. In other words, the first molding die is largely divided into a molding die and a vacuum plate.

At this time, the molding mold is pre-processed to have an appearance according to the manufacturing intention and design required for the original plate (the initial state of the lamp shade) seated to the top, which is independent of any particular shape or shape, and manufactured separately It is realized by a process (cutting process etc.).

At this time, the molding mold is formed in the inner circumferential surface, the space portion formed at least one decorative surface and through-hole (communication with the vacuum control tube connected to one side of the vacuum plate to enable suction) when the vacuum compression described later As the original plate is strongly adsorbed, the outer surface of the lampshade is embossed or engraved to make it more luxurious and beautiful.

In other words, the outer circumference of the lampshade is absorbed by vacuum as if it is stamping various patterns, rather than a simple pattern, which forms the appearance (the overall shape) of the lampshade (by using a pneumatic pressure by vacuum pump). The separate decorative surface formed in the pattern processing by the press working is formed, which has the effect of already performing two times in one operation.

At this time, the bent separate contact plate is placed on the open outer peripheral surface side of the molding mold, which is machined according to the outer design of the lampshade according to the manufacturing intention and design requirements, the outer molding frame of the second molding frame to be described later It is made to be pressed and molded during transportation.

In other words, it responds to the infinite changes in design required and forms bends such as "a" and "b" on the outer periphery of the lampshade in addition to the surface of the lampshade. When the compression is induced to form the above-described outer peripheral surface design by the upper and lower adhesion.

At this time, the vacuum plate is wrapped around the upper outer peripheral surface of the molding die, and is coupled to maintain the vacuum, the vacuum plate including the fixed mold is fixed to the through-hole of the above-described first base is welded, so that the inner space portion The vacuum part is formed.

At this time, a separate vacuum intermittent tube is installed on one side of the outer circumferential surface of the vacuum plate to be fastened to the pneumatic hose of the vacuum pump, which will be described later. Inhalation to facilitate closure.

That is, the hemispherical shaped mold shown as one embodiment serves as a kind of cover (packing) by the original plate is seated on the upper side, while the vacuum state is performed from the vacuum pump through the air through the space of the molding die After the vacuum part of the vacuum plate is sucked into the vacuum tube.

On the other hand, the second molding frame 300 is moved up and down by the fixing cylinder 310 fixed on the surface of the second base 200 of the frame, and the rod side of the fixing cylinder 310, the first The outer circumferential mold 320 is formed to press-mold the outer circumferential surface of the original plate 10 inserted therebetween to correspond to the mold-mould-contact plate 214 of the mold.

At this time, the outer molding frame 320 of the second molding frame is provided with a plurality of fixing clamps 321 on the outer circumferential surface so that the sealing when reinforced in close contact with the first molding frame 200 including the original plate (10). It is preferably formed.

The fixing clamp has a hinge portion formed at an upper portion thereof, and is fastened to a close plate of the first molding die by a link that rotates in a clockwise or counterclockwise direction and a fastener formed at the other end of the link to promote a firm sealing. .

That is, as a separate auxiliary means to double the pressing force of the fixing cylinder, it is formed to tighten the outer peripheral surface of the original plate more strongly.

At this time, the fixing cylinder 310 is preferably a capacity of 10ps (horsepower). This is usually based on the fact that the synthetic resin material formed of acrylic or glass is not more than 5cm when used as a lampshade, which is not dependent on the plus capacity of the cylinder.

On the other hand, the third molding frame 400 is transported up and down by the main cylinder 410 fixed on the surface of the third base 300 of the frame and the rod side of the main cylinder 410, the second base And the second molding die is transported without interference, while the rod-side end is formed with a separate pressing mold 420, the decoration 430 is processed toward the bottom is formed to press the upper surface of the original plate (10).

At this time, the main cylinder 410 and the fixing cylinder 310 is preferably a capacity of 10ps (horsepower). This is usually based on the fact that the synthetic resin material formed of acrylic or glass is not more than 5cm when used as a lampshade, which is not dependent on the plus capacity of the cylinder.

In this case, the pressing mold is pressed in correspondence with the decorative surface of the above-mentioned molding mold, which is to be pressed once more for clear stamping of the original plate to be carved into the decorative surface shape.

That is, by transferring the secondary third molding die (press molding die) to the first molding die (original plate in the molding die), it is formed to more clearly and precisely imprint the vivid aesthetics required in the design.

For reference, the vacuum pressing process using only the first molding frame has a weak adsorption, making it difficult to provide a clear decorative surface to the outer circumferential surface of the original plate.

At this time, the decoration to be imprinted on the bottom of the pressing mold is made to be embossed or engraved according to the operator's choice.

In addition, the vacuum pump 500 is connected to the vacuum interposer tube 222 of the vacuum plate of the first molding die, the original plate 10 seated on the upper contact plate 214 as the inner peripheral surface shape of the molding mold 210 Inhalation and vacuum tight contact.

At this time, the vacuum pump 500 preferably has a capacity of 5 ~ 15kgf / ㎠.

At this time, the vacuum pump is formed with a pneumatic hose on one side, such a pneumatic hose is connected to the vacuum control tube of the first molding frame is made to perform the vacuum compression in accordance with the set value required by the inverter.

On the other hand, the lamp shade of the present application by the manufacturing apparatus, as shown in Figure 5, the preheating step (S100), the first molding step (S200), the second molding step (S300), the third molding step (S400) And, it is manufactured by the finishing step (S500).

Thus, the preheating step (S100) is preheated by a separate heater (not shown) to the original plate 10 of the synthetic resin material including acrylic, glass to 150 ~ 155 ℃ temperature is formed in a soft state of soft material.

This soft state is intended to induce it to be more flexibly seated on the space portion (inner circumferential surface) of the molding die when placed on the molding die top contact plate of the first molding die and subjected to vacuum compression.

At this time, the heating temperature is based on the value of the synthetic resin material as a plate shape of less than 1 ~ 5cm bar, if the thickness is a little thin on the basis of the temperature is slightly lower, on the contrary, if the thickness is a little thick, the temperature is set a little higher It is preferable.

Meanwhile, in the first molding step S200, the preheated original plate 10 is seated or aligned on the first molding frame 200 of the apparatus, that is, the upper contact plate 214 of the molding mold, and quickly the second molding plate 10. The outer molding frame 320 of the molding die is fixed to the outer peripheral surface of the original plate 10 prepared by transferring a force of 10 ps (horsepower) downward through the fixing cylinder 310, and the original plate 10 The outer circumferential surface thereof corresponds to the bending surface 214a pre-machined to the contact plate 214 of the molding die and adds an outer circumferential shape.

That is, as a step of vacuum-compressing the original plate added with ductility to conform to the shape of the space of the molding die, the outer circumferential surface of the original plate is seated on the contact plate, and the outer molding frame of the second molding frame is lowered from the top. In contact with the plate itself is formed to provide a vacuum cover.

On the other hand, in the secondary molding step (S300) is the outer peripheral surface of the original molded plate 10 is pressed by the outer molding frame 320 and the contact plate 214, thereby causing the space portion 211 of the molding mold The original plate 10 itself is to promote a sealed space, the vacuum pump 500 is a vacuum intermittent tube of the vacuum plate to guide the space portion 211 of the molding die in a vacuum state of 5 ~ 15kgf / ㎠ ( 222 and the through-hole 213 of the molding die to promote the space portion 211 in a vacuum state, the original plate 10 by the vacuum state is adsorbed on the inner peripheral surface and decorative surface 212 of the molding mold 211. Thus, the machined shape and pattern are closely adhered to one side.

At this time, the outer mold and the contact plate has an outer circumferential surface of the male and female shape or the fitting coupling shape corresponding to each other it is designed to a certain shape on the outer circumferential surface of the original plate by the adhesive force transferred up and down by the fixing cylinder.

In other words, the outer circumferential surface shape is additionally processed by the outer circumferential surface support fixing of a simple original plate without a separate additional press process, and thus according to the mold shape and the pressing (close contact).

At this time, in order to double the force of the outer mold close to the original plate according to the thickness of the original mold is formed a plurality of clamps arranged at equal intervals to promote a more strong sealing or fixing force.

On the other hand, the third molding step (S400) is the upper surface of the original plate 10 adhered or adsorbed to the inner circumferential surface of the molding mold 210 by the vacuum pump 500, the pressing mold 420 of the third molding die 10ps It is conveyed downward by the force of (horsepower) is formed to add the clarity of the decorative surface 212 or to further carve a separate decorative pattern.

This induces the decorative surface to be imprinted more clearly on the original plate surface. In particular, a separate decoration is imprinted on the bottom of the crimping mold so that various designs can be worked on in one direction or in other directions (that is, on both sides). To be processed.

On the other hand, the finishing step (S500) is the first and second, the third molding step (S200, S300, S400) is returned in the reverse order, the original plate being cured in the space portion 211 and the contact plate 214 of the molding die ( After removing 10), the outer peripheral surface is formed to be polished or cut.

At this time, the removal of the original plate is to be removed before the preheated original plate temperature is so low that it is completely cured in the molding die, which is dependent on the thickness of the original plate, the processing speed of the first and second molding steps By setting, the removal point is also set at the same time.

That is, the original plate removal is separated by manual operation of the operator and is released without delay when the three-step process is completed.

Thus completed original plate, that is, as shown in Figure 6, the lamp shade of the present application is finished by finishing the outer peripheral surface by a separate grinding machine or cutting machine.

As described above, the present invention avoids the conventional manufacturing apparatus and manufacturing method of sequentially processing various appearances of the lampshade and various patterns imprinted on the appearance of the lampshade to be manufactured so as to process the double (two or more) operations in only one operation. While forming a device, the lampshade processed by the above-mentioned work forms a smooth outer circumferential surface, thereby improving the aesthetics of the aesthetics, and having an embossed or engraved pattern on the surface of the lampshade to more clearly imprint.
