Description

Replica structure of vinyl record mold

This creation is about the field of vinyl record molds, especially the structure of a replica mold directly using vinyl records.

Vinyl record, also known as gramophone record, is the name used to play a record on a disc player. It is a black disc-shaped film. It was originally made of graphite. After that, it used shellac and was later used. Polyvinyl chloride (PVC) is pressed. The pits are engraved with bumps to record sound. The early vinyl records were only mono, and later developed into a two-track two-channel track.

The first step in making a vinyl record is to make a mold that records and converts the source of the music provided into a pressed record, also known as the master. The audio signal is engraved on the copper disc by the engraving machine to form a straight metal master. The pit on the master is the same as the pit on the record, so the master can be used for playback, but it cannot be used directly to suppress the record. It is necessary to process the master plate and make the master mold before mass production.

In the 1970s, the status of vinyl was like the Compact Disc (CD) of the 1990s. It is the main carrier of music and a collective memory of an era. However, with the development of technology, cassette tapes, CDs, digital files, streaming music, etc. have appeared one after another, and vinyl has entered history.

The status of a vinyl record has a great influence on the sound quality of listening to vinyl records. To keep the record in good condition, you need to use a better quality inner bag to achieve better protection. Most of the inner bags have anti-static functions, some of which have a moisture-proof effect, and the static electricity is reduced, so that the dust does not adhere to the vinyl surface.

Today, the sales of vinyl records have resumed again, making more people pursue, but because of the difficulty of storing vinyl records. Many of the high-quality vinyl records masters saved by the record companies were damaged in succession, and the preserved masters could not hear the original sound recorded at that time.

Therefore, as apparent from the above description, the development of a problem that overcomes the above-mentioned shortcomings in the preservation and the reproduction of the original sound recorded at that time is a subject to be solved by those skilled in the art.

Therefore, in view of the above-mentioned shortcomings, the creators of this creation have collected relevant information, and have designed and developed such new patents through continuous evaluation and modification through multi-party evaluation and consideration, and through years of experience in the industry.

In order to achieve the above object, the present invention provides a replica structure of a vinyl record mold, which comprises a vinyl record and a master mold. The first surface of one of the vinyl records has a track groove. The master mold covers the vinyl record, and the master mold includes a first mold layer and a second mold layer. The first mold layer has an opposite second surface and a third surface, the second surface is attached to the surface of the track groove and the first surface, and the second mold layer has a fourth surface of the third surface, and the fourth surface is attached to the third surface. Through the above, the replica structure of the vinyl record mold can be achieved.

The above-mentioned replica structure of a vinyl record mold, wherein the first mold layer is a nano metal layer having a first thickness.

The above-mentioned replica of the vinyl record mold, wherein the second mold layer is a metal layer having a second thickness and the second thickness is greater than the first thickness.

Further, the replica structure of the vinyl record mold, wherein the nano metal layer is stacked by precision electroforming.

Further, a replica structure of a vinyl record mold in which the metal layers are stacked in a precision electroforming manner.

Moreover, the above-mentioned vinyl record mold re-engraving structure, wherein the metal of the nano metal layer is composed of nano gold, nano silver, nano copper, nano palladium, nano platinum, nano nickel, nano One, two, or a combination of cobalt and nano bismuth.

Moreover, the above-mentioned replica structure of the vinyl record mold, wherein the first thickness is between 5 nm and 20 nm.

Furthermore, the above-mentioned vinyl record mold has a replica structure in which the metal of the metal layer is composed of one, two, or a combination of gold, silver, copper, platinum, nickel, cobalt, rhodium.

For the prior art, the effect of this creation is:

1. Directly use the commercially available and well-preserved vinyl records to make molds, reducing the cumbersome process.

2. Replace traditional plating with electroforming to make the mold a mold that achieves higher hardness and conductivity.

Precision electroforming technology originated from the LIGA (lithographie galvanoformung abformun) process in Germany and is one of the key technologies in this process. The primary purpose of using electroforming technology is to obtain a metal mold with the same appearance as the prototype, replicating extremely precise and extremely complex prototypes.

Precision electroforming technology has the following advantages:

1. The electroforming material and its mechanical properties can be adjusted by controlling the composition of the electroforming liquid. For example, electroforming can be formed into a single metal or alloy material to increase the hardness of the electroformed layer. For example, the Rockwell Hardness Number (HRC) of a nickel electroforming mold is about 30 HRC, and the hardness of the nickel-cobalt alloy electroforming mold. There are about 50 HRC.

2. Prototype molds are not limited in shape and size, ie they are not affected by geometry, whether stereo or flat.

3. Molds of the same appearance or different appearance can be manufactured in small or large quantities.

4. When the surface roughness of the prototype mold is on the nanometer scale, the surface roughness of the metal mold after precision electroforming can still reach the nanometer level. This also shows that the accuracy of the copy can be controlled to nearly 100%.

The present invention will be described in detail below with reference to the accompanying drawings. Referring to FIG. 1 to FIG. 5, a replica structure 1 of a vinyl record mold includes a vinyl record 2 and a female die 3.

One of the first surfaces 21 of the vinyl record 2 has a track groove 211.

The master 3 is covered by the vinyl record 2, and the master 3 includes a first mold layer 31 and a second mold layer 32.

The first mold layer 31 has an opposite second surface 311 and a third surface 312. The second surface 311 is attached to the surface of the track groove 211 and the first surface 21. The first mold layer 31 is a nano metal layer and is stacked by precision electroforming, and the metal thereof comprises nano gold, nano silver, nano copper, nano palladium, nano platinum, nano nickel, nano cobalt. A combination of one, two, or more of nano bismuth having a first thickness H1. The first thickness H1 is between 5 nm and 20 nm.

And the second mold layer 32 has a fourth surface 321, relative to the third surface 312, and the fourth surface 321 is attached to the third surface 312. The second mold layer 32 is a metal layer and is stacked in a precision electroforming manner. The metal of the second mold layer 32 is composed of one, two, or a combination of gold, silver, copper, platinum, nickel, cobalt, rhodium. And having a second thickness H2 and the second thickness H2 being greater than the first thickness H1.

Through the above, the replica structure of the vinyl record mold can be achieved 1 and the effect of the creation is:

1. Directly use the commercially available and well-preserved vinyl record 2 to make molds, reducing the cumbersome process.

2. Replace the traditional electroplating with electroforming to make the mold reach higher hardness and conductivity. It can directly reduce the wear and reduce the wear after mass production, resulting in higher efficiency.
