V. Inventive Command [Field of Invention]

The present invention relates to a type of acrylic stick with decorative pattern, A-coat, Wanfa and Dream Class, especially a kind of solid acrylic that uses acrylic material as a matrix and emits inner, line and spiral patterns. Bar. < Straight [Background of the Invention] In the pressure of the consumer, and its business operator announced the announcement, the mold cavity under the acrylic plate was melted, and the acrylic plate was changed according to the upper and lower melting plates to change a variety of acrylic materials. The solid body breaks the tradition. After the dense mold cavity required for solidification is solidified in advance in the 384252 manufacturing method, that is, the surface is made today. Xu Tong's choice, whether it is in the board, does not contain any invention. Any decorative material, even acrylic or bar, but the acrylic invention of the decorative material is a type, which mainly injects the injection mold with an appropriate thickness of acrylic flowers, leaves or its acrylic The molten acupuncture point was obtained by infusion and pressing to obtain a highly transparent, authentic method. Previously, the degree was sprinkled on the pressure, and the upper mold material was also not used to produce high-transparency horizontal melts with monochromatic power plates in the society, and the linings were used to melt the pressure, and the actual performance was exceptional. , The method of impacting the raw material structure, the decorative material -iA-ge5 is placed again, the injection mold for the effect of acrylic is to be the appearance of the acrylic

^ However, the above method is limited to the manufacturing method of sheet acrylic, and there is a line running through the finished product at the parting line of the finished product. Therefore, this method is not suitable for forming acrylic rods. Based on many years of continuous experience, the inventor has invented a method and device that can make solid acrylic rods integrally formed into a multi-style decorative pattern inside. [Objective of the invention]

504469 V. Description of the invention (.2) The main purpose of the present invention is to enable the interior of acrylic solid bars to have decorative patterns. In order to solve the above problems, the present invention uses two or more injection machines through a common mold. Shoot straight solid acrylic bars with multicolor decorative patterns or other forms of decorative patterns, decorative blocks, etc. Another object of the present invention is to make the above-mentioned multi-colored decorative linear solid acrylic bars more variable. Therefore, a rotating device is used to link with the common mold to rotate them simultaneously during the injection process. , And form a solid acrylic bar with a spiral pattern inside.

The detailed description and technical contents of the present invention are described below with reference to the drawings: Please refer to "Figures 1, 2, 3" at the same time, which is a flowchart of the process steps, process operation flowcharts, and components of the present invention. As shown in the figure, the present invention is a method for manufacturing an acrylic rod with a decorative pattern, which includes the following steps: (a) Injection step A: Putting acrylic material into the injection device 1, and then passing through the injection device 1 The acrylic raw material is extruded into the die set 2 and is formed into a predetermined shape (A1) through the die set 2.

(b) Setting step B: The formed shape is cooled and solidified by the cooling device 3, so that the shape can be set (B 1). (c) Traction step C: The traction device 4 is used to guide the shape so that the shape on the production line remains continuous (C 1). (d) Cutting step D: The above-mentioned continuous body is cut to a desired length (D 1) by a cutting device 5. In the above injection step A, the injection device 1 has a plurality of

Page 5 504469 V. Description of the invention (; 3) injection molding machines 1 1, all of which are connected to the mold group 2, and the mold group 2 is composed of the first mold 21 and the second mold 22, when operated After the various colors of acrylic colorants are extruded into the first mold 21 through the injection molding machines 11 to make them multi-colored decorative patterns, they are shot together through the second mold 2 2. Then, it will become acrylic molded product 6, please refer to "Figures 4-1, 4-2 and Figures 5-1, 5-2" together with the attached drawings I, II and III. The pressure-molded product 6 can be an acrylic solid bar with a multi-colored decorative pattern 6 1 or an acrylic solid bar with a plate-shaped decorative pattern 6 2. And the shape ejected from the injection device 1 is still in a high temperature state, so it still has extremely high plasticity. Therefore, it is necessary to use a rapid cooling method to cool and shape the shape. The second step is the setting procedure B, which is used immediately. The styling device 2 for fast fixing the shape of the aforementioned body, and after the shape still has a high temperature, after passing through the sizing device 2, the acrylic molding 6 can be cooled and the purpose of fixing the shape of the body can be achieved. One less ★ Next, after the acrylic molded product 6 is cooled and fixed, the second step traction program c is immediately followed by a traction device 4 to control the speed of all production processes and synchronously and continuously take the acrylic molding Product 6, shape = after the second mold 22 is shot, all are-continuous. Make it-table poems into the fourth step of the cutting process D, through the cutting device 5 can be # 八 边 成 1 扣 6, according to demand cut into a suitable length of π 〇 to meet customer needs and Conducive to handling operations. 〇 In addition, please refer to "筮 〇 ', mold 2 2 *, connection diagram", the second% of the mold group 2 moving device 7 (the rotating device 7 is-horse

504469 '' Fifth, the description of the invention (&) ", so that the second mold 22 can be rotated at the same time during the injection process, so that the multi-color decorative patterns formed inside the acrylic molded product 6 appear to rotate, Acrylic core rods with spiral patterns are formed (see the attached drawings 4 and 5). Based on the above, we can provide consumers with a solid acrylic rod with decorative patterns. And make it have a variety of different patterns to choose from, so as to increase the willingness to buy. However, the above are only the preferred embodiments of the present invention. When the scope of implementation of the present invention cannot be limited by it, that is, all equivalent changes and modifications made in accordance with the scope of the patent application of the present invention shall still belong to the invention patent.
