Method for forming tin plate

Abstract

To solve the following problem: in a conventional manufacturing method using a wooden mold, there is a limitation that a width of a fine concave portion cannot be expressed by casting, a restriction is imposed on design, and freedom of expression is lost.SOLUTION: The method solves the problem by pouring molten tin together with a substrate on which a pattern is printed by a printer, thereby transferring the printed pattern on the substrate onto a tin plate.SELECTED DRAWING: Figure 5

Description

[Technical Field]

[0001] The present invention relates to a molding method for transferring a pattern printed on, for example, paper onto a tin plate. [Background technology]

[0002] When creating a pattern on a tin plate, if a wooden mold is used to form the pattern, the outline of the pattern must be cut out of the wooden mold. It is also possible to form the pattern by cutting or pressing the plate itself, but both of these methods are expensive to produce. Summary of the Invention [Problem to be solved by the invention]

[0003] Conventionally, when applying various patterns to cast plates produced by casting, there are problems such as the inability to produce thin lines, which imposes design restrictions and reduces freedom of expression.

[0004] Furthermore, the manufacturing costs are high due to the cost of cutting wooden patterns and plates when applying patterns, as well as the cost of creating the related cutting data. To provide a method for producing a tin plate which increases the degree of freedom in designing a pattern, and allows the enjoyment of various designs at low cost. [Means for solving the problem]

[0005] In order to solve the above problems, the present invention provides a tin plate molding method comprising a printing step of printing a predetermined pattern on a base, a base fixing step of fixing the base to a lower mold, a spacer fixing step of fixing a spacer that surrounds the base and is a predetermined thickness greater than the base, an upper mold fixing step of fixing an upper mold to the lower mold with the base and spacer sandwiched between them, and a pouring step of pouring molten tin through an opening formed in the spacer.

[0006] The tin plate molding method of the present invention, configured as described above, is characterized in that various patterns are printed on paper by a printer and then cast, and the printed patterns are transferred to the tin plate. The thickness of the tin plate can be changed by changing the thickness of the spacer. [Effects of the Invention]

[0007] In the present invention, the pattern is transferred to the tin plate simply by pouring molten tin into the upper and lower dies with a spacer and paper with a printed pattern sandwiched between them, which simplifies production and reduces costs. Also, by making the spacer thinner, a thin tin plate can be produced, and by making the spacer thicker, a thicker tin plate can be produced.

[0008] The tin plate produced by this invention has excellent corrosion resistance and can be decorated with various patterns on its surface. In addition, because the tin plate of this invention is flexible, it can be easily bent, making it possible to produce tableware of any shape. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0010] An embodiment of the present invention will be described with reference to the drawings. The apparatus for forming tin plates of the present invention is composed of a base 2 made of, for example, paper, a lower mold 1 on which the base 2 is placed, a spacer 3 placed on the top of the base 2, an upper mold 4 placed on the top of the spacer 3, and a clamp material 5 for clamping and fixing the lower mold 1 to the upper mold 4.

[0011] The lower mold 1 is made of wood and has a rectangular shape, and protrusions 1a, 1a are formed on both upper corners to prevent molten metal from leaking. The upper mold 4 is also made of wood and has a rectangular shape with the same width as the lower mold 1.

[0012] The base 2 is made of paper, and a floral or other pattern is printed on the paper using a printer. The spacer 3 is made of cardboard with a thickness of, for example, about 0.5 mm. The center of the spacer 3 is cut out, leaving a width of, for example, about 15 mm, and the size of the cut-out portion determines the size of the tin plate 6. Furthermore, a notch 3a is formed on the upper edge of the spacer 3, which serves as an injection port for injecting molten tin. The spacer 3 is designed to hold down the periphery of the base 2.

[0013] We will now explain the molding method for the device used to manufacture the tin plates mentioned above. First, a pattern is printed on the base 2 using a printer (not shown). The base 2 is shaped so that it does not overlap the protrusions 1a, 1a of the lower mold 1. Next, the base 2 is set on the flat part of the lower mold 1. From this set state, a spacer 3 is placed on top of the base 2. Then, the upper mold 4 is set on top of the spacer 3, and the upper mold 4 and lower mold 1 are fixed at four points using clamps 5 (see Figure 5).

[0014] As described above, the lower mold 1 and upper mold 4 are fixed with the clamp 5, and then molten tin (not shown) is poured into the spacer 3 with the injection port 3a facing up. After this, once the poured tin has solidified, the clamp 5, upper mold 4, and spacer 3 are removed in that order, and the tin plate 6 is removed.

[0015] In the above explanation, the thickness of the spacer 3 was set to 0.5 mm, but it may be set to, for example, 1 mm or even 3 mm. Also, although the pattern to be transferred to the tin plate was explained as a floral design, it is also acceptable to print seafood, geometric patterns, etc. [Explanation of symbols]
