.a a 9* Name of Applicant: Actual Inventor Address for service is: Der-Ming HSIEH Der-Ming HSIEH WRAY ASSOCIATES 239 Adelaide Terrace Perth, WA 6000 Attorney code: WR Invention Title: "Method for Manufacturing a Raw Material for a Prototype and the Raw Material Thereof' The following statement is a full description of this invention, including the best method of performing it known to me:- '/2 METHOD FOR MANUFACTURING A RAW MNATERIAL FOR A PROTOTYPE AND THE RAW MATERIAL THEREOF The present invention relates to a method for manufacturing a raw material for a prototype and the raw material thereof.
Typically, a prototype is required to be first made for making an article by means of such as an injection molding process. The prototype is then used to make the mold which may be used for molding the desired articles in a fast speed. The prototype is usually made of a wood material or a metallic material. However, the wood material includes a lot of fibers and veins so that the prototype made of the 1 l wood material may not be made with a smooth appearance. In addition, the wood oO*.
material easily absorbs moisture, and is easily deformed and broken. Further, the S wood material has a bad strength. On the other hand, the metallic material is heavy, thereby increasing the time for machining the metallic material. In addition, the metallic material has a great strength and hardness so that is not easily machined and mended.
oooS The closet prior arts are disclosed in U.S. Patent No. 5,041,472 to Myer, entitled "SYNTACTIC FOAM ENERGY ABSORBER", and U.S. Patent No.
4,681,718 to Oldham, entitled "METHOD OF FABRICATING COMPOSITE OR ENCAPSULATED ARTICLES".
The primary objective of the present invention is to provide a method for manufacturing a raw material for a prototype, including the steps of providing a predetermined quantity of hollow powder made of ceramics, glass, or resin, and a predetermined quantity of resin made of epoxy, polyethylene, polypropylene, or polyester; mixing and stirring the hollow powder with the resin to form a mixed material; evacuating the mixed material to remove gas bubbles formed between the hollow powder and the resin of the mixed material; forming the mixed material into a predetermined shape; maintaining the mixed material that has a predetermined shape at a first predetermined constant temperature ranged between 10°C and -20°C during a first predetermined period of time ranged between 4 hours to 120 hours to crystallize and cure the hollow powder and the resin; heating the mixed material to a second predetermined temperature ranged between 60°C and 110 °C during a second predetermined period of time ranged between 4 hours to 8 hours to further crystallize and integrally cure the hollow powder 10 and the resin 11 so as :16 to form a raw material; removing the raw material; and dressing the raw material.
The predetermined quantity of hollow powder has a weight within the range of about 2 to 50 unit weights, and the predetermined quantity of resin has a weight of about 100 unit weights.
"I Another objective of the present invention is to provide a raw material for a prototype including a predetermined quantity of hollow powder, and a predetermined quantity of resin mixed with said hollow powder for curing said hollow powder together so as to form said raw material with a predetermined structural strength.
Further objectives and advantages of the present invention will become apparent after a complete reading of the detailed description with reference to the accompanying drawings.
In the drawings: Fig. I is a flow chart of a method for manufacturing a raw material for a prototype according to the present invention; Fig. 2 is a plan cross-sectional view of the raw material according to the present invention; and Fig. 3 is a perspective cross-sectional view of the raw material as shown in Fig. 2.
With reference to Figs. 1-3, a method according to the present invention is used for manufacturing a raw material which is used for making a prototype which is used for making a mold. The raw material includes a plurality of hollow powders mixed with a resin 11 which may cure the hollow powders 10 together so as to form the raw material with a predetermined structural strength. Each of the hollow powders 10 contains a space 12 defined therein. The hollow powder 10 is made of ceramics, glass, resin or the like. The resin 11 is made of epoxy, polyethylene, S" polypropylene, polyester or the like.
The method includes the steps of material providing step: providing a predetermined quantity of hollow powder 10 and a predetermined quantity of resin 11; mixing step: mixing and stirring the hollow powder 10 with the resin 11 to form a mixed material; vacuum gas bubbles removing step: evacuating the mixed material in a chemical or mechanical manner to remove gas bubbles formed between the hollow powder 10 and the resin 11 of the mixed material; injection molding step: placing the mixed material into a die (not shown) for forming the mixed material into a predetermined shape; constant temperature curing step: maintaining the mixed material that has a predetermined shape at a first predetermined constant temperature ranged between -10OC and -20 0 C during a first predetermined period of time ranged between 4 hours to 120 hours to crystallize and cure the hollow powder 10 and the resin 11; secondary curing step: heating the mixed material to a second predetermined temperature ranged between 60"C and I "C during a second predetermined period of time ranged between 4 hours to 8 hours to further crystallize and integrally cure the hollow powder 10 and the resin 11 so as to form a raw material; mold removing step: removing the raw material; and (h) dressing step: dressing the raw material.
In the step the predetermined quantity of hollow powder 10 has a weight within the range of about 2 to 50 unit weights, and the predetermined quantity of resin 11 has a weight of about 100 unit weights.
In the step the mixed material is maintained at the constant temperature 1 between -10 0 C and -20°C during the period of time from 4 hours to 120 hours so that the hollow powders 10 and the resin 11 are gradually crystallized and cured to form a fine and entire crystal. Then, in the step the mixed material is heated to the temperature between 60°C and 110°C during the period of time from 4 hours to 8 o*o• hours so that the hollow powders 10 and the resin 11 are integrally crystallized and :15 cured, so as to enhance the toughness and stability of the mixed material. By means of the constant temperature curing step in conjunction with the secondary curing step it is able to prevent the prototype from being contracted and deformed, and is able to reinforce the toughness and stability of the prototype.
The hollow powders 10 are secured with the resin 11, but a small gap is defined therebetween. In addition, the resin 11 itself has certain elasticity and toughness so that the prototype made of the hollow powders 10 and the resin 11 has a structural strength smaller than that of the metallic material and greater than that of the wood material. Accordingly, the prototype is easily machined, and has a sufficient strength and a reduced weight. In addition, the prototype made of the powders and the resin does not absorb moisture, and cannot be easily deformed so as to solve the problems encountered by the wood material which easily absorbs moisture and is easily deformed. Further, the prototype made of the powders and the resin is easily machined, and is easily mended so as to solve the problems encountered by the metallic material which is not easily machined, and is not easily mended.
Although the present invention has been described with a certain degree of particularity, it is to be understood that the present disclose has been made by way of example only and that many other possible modifications and variations can be made I without departing from the scope of the present invention.
Throughout the specification, unless the context requires otherwise, the word "comprise" or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated integer or group of integers but not the exclusion of a o any other integer or group of integers.
