In order to achieve the above object, the polymer molding method provided by the present invention comprises the steps of: &, using a first die, the side surface of the first die is concavely provided with a predetermined depth a die hole; the t-die is capable of - the side face and the side face of the first die are attached to each other 'the ribs are used to form a blank mold chamber; The m sub-material is separated from the two mold pieces of the corresponding shape by the external injection mold chamber, and the first blank material is attached to the first mold cavity due to the mourning One of the side faces of one of the dies; d, the second dies of the second dies are formed such that one side of the slab faces the side of the first dies, and one side of the third dies is tied to the first The cavities are butt-joined to form a molding cavity between the two pieces; the younger brother presses the second shape of the predetermined shape to fill the predetermined position of the cavity of the third die; 1, 3^=^? And the first dies are attached to each other in the molding cavity, and are attached to each other; [Embodiment] 1267434 Hereinafter, the present invention is A preferred embodiment is further described in conjunction with the drawings, wherein: • The first drawing is a manufacturing flow diagram of a conventional technical content. • The second diagram is a manufacturing flow diagram for another conventional technical content. The third drawing is a manufacturing flow diagram of a preferred embodiment of the present invention. Referring to the third embodiment, the polymer molding method provided in a preferred embodiment of the present invention comprises the steps of: laminating a mold formed by stacking three layers of molds. 1〇), and a first cavity (111) of a suitable depth is recessed on the lower surface of the first die (11) #, and is disposed on the top side of the second die (12) a second cavity (121) corresponding to the first cavity (ι), and a third cavity (131) of a suitable depth on the upper surface of the third die (13), When each of the die pieces (11) (12) (13) is placed on top of each other in a die state, the second cavity (121) and the first cavity (111) are butted against each other for each A blank mold chamber (14) is formed between the first and second mold sheets (11) (12); in order to shorten the process time, the mold (1〇) can have a considerable temperature in this embodiment. In other words, the temperature of the mold (10) is maintained above the reaction temperature of the &amp; prototype material, in order to avoid the process time for the mold (10) to rise and fall; b. Mold 10) In the mold state, the external high-knife raw material is melted below the reaction temperature by the injection machine, and then injected into the blank mold (14) through the flow passage to be used by the blank mold chamber (14). Molding the first blank (21);, : c, causing the mold (10W to separate each of the dies 1) (10) (10) from each other, at an appropriate distance from each other, and to make the first blank ( 2)) being embedded in the first mold cavity (111) and attached to the lower side of the first die (11) to horizontally traverse the second die (12) The first and third dies 1267434 (10 (13) are out of the range of the upper displacement operation; d, lowering the surface temperature of the third cavity (131) of the third dies (13) with a low temperature gas, and then having a predetermined Forming a second blank (22) at a suitable position of the third cavity (131); e, replacing the second die (12) with the third die (13) and the first die The sheet (11) is attached so that the third cavity (131) and the first cavity (111) are butt-joined to form a molding cavity (15), and the second blank (22) is The first blank (21) is The molding cavity (15) is oppositely abutted; f. providing appropriate pressure to maintain the mold (10) in a mold state, so that the heat energy of the mold is gradually transferred into the interior of the molding cavity (15). And each of the blanks (21) (22) is brought to a reaction temperature suitable for the reaction to carry out a chemical reaction, thereby obtaining a molded product (2〇) according to which a desired shape is molded. The physical properties such as the color or density of each of the blanks (21) and (22) are not limited, and the method is implemented in different colors or different densities; In the step d, the process of reducing the surface temperature of the second cavity (131) by the fluid may be based on a factor of whether the shape of the second blank is deformed by temperature, and in other words, a selective procedure, in other words,苟When the second blank material occupies a considerable volume and thickness, and is not easily deformed under the action of a short time temperature, the process of lowering the surface temperature can be omitted without performing as to what kind of fluid should be selected. For the protection requested in the original application, it is no longer As stating. Through the above methods, the effects of the present invention which can be achieved by the prior art are at least as follows: Second, the situation of avoiding mixing occurs, the cover, in the present invention, each of the blanks (2丨) (22) When the molding chamber (15) is combined, it is not carried out under the action of high pressure as in the conventional technology. [This is done to avoid the occurrence of spoilage of the billet on the contact surface due to the relative flow of the billet. Happening.
