Its identification.

According to the conventional method for manufacturing a hollow blow molding unit, the method comprises the following steps: (A) cutting and expanding the billet: pressing the heated semi-solid thermoplastic material from the die and continuing to the center of the die Blowing, and kneading and closing the bottom end of the billet which has been extruded at an appropriate distance, so that the continuously poured supply gas can force the billet to be expanded and expanded; (B) clamping pressure and cutting Billing material: When the male and female molds are clamped and pressed toward each other, the expanded billet can be cut; (C) re-injection: the injection tube that has been placed on the inner mold of the male mold can be directly inserted and continued Injecting into the above-mentioned cut expanded billet until the molten semi-solid expanded billet is completely adhered to (D) Cooling molding: using the cooling flow channel inside the mold to make the molten semi-solid expanded billet begin to cool and solidify; (E) Finished product: the male and female molds are retreating The mold is separated so that the solidified expanded billet can be completely separated from the male and female molds, and a finished product can be obtained.

Although the above-mentioned creations can achieve the original purpose of creation, they are highly praised by the industry and the general operators. However, in view of the industry's continuous innovation and breakthrough in research and development and technology, the applicants have made more efforts to study. Improvement, and make it perfect and practical; plus, the creator has responded with numerous updates to the experimental test and the actual use of the consumer, and found that the following problems still need to be further improved:

1. Because the materials of general air blow molding units (such as buckets, washbasins, pots, boxes, plates, boxes, etc.) are mainly made of monochrome PE plastic materials, and when molding, the brand logo of customers will also be The plastic barrel is completed at the same time, so that the formed barrel is only in a single color, so it is impossible for the consumer to immediately recognize the customer's brand trademark as a major problem.

2. In order to improve the above-mentioned defects, the manufacturer will attach the formed elements (such as buckets, washbasins, pots, boxes, plates, boxes, etc.) to the secondary processing (such as screen printing, etc.) after molding. The customer's brand trademark temporarily solves the above-mentioned lack of traditional manufacturing methods. However, the construction site often touches the oil stains, or accidentally slams or scratches when moving, which often causes the color layer of the surface to fade. Or remove it for another big problem.

3, as mentioned above, although the screen printing process can make the top surface of the unit (such as: bucket, washbasin, potted, box, plate, box, etc.) achieve multi-color recognition, however, in the single The secondary surface of the element, or the bottom surface formed between adjacent ribs on the surface of the cell, can still not use the screen printing process to achieve the multi-color recognition effect, which is another trouble for the industry and needs to be treated. The problem to be solved.

Therefore, how to develop a stereoscopic representation of the recognition surface layer and a color change with three or more colors is a technical problem that the current industry urgently needs to solve urgently. In view of the above, the present invention proposes a hollow blow for the lack of the above-mentioned prior art. The gas forming unit uses a stereoscopic recognition device to effectively overcome the above problems in order to benefit all consumers and manufacturers.

The maximum dimension B1 of the cross-sectional width and the cross-sectional width dimension of the identification surface layer 30 are not smaller than the minimum dimension B2 of the cross-sectional width of the concave-shaped identification unit 16 of the relative position or the cross-sectional width of the identification surface layer 30. The minimum dimension C1 of the cross-sectional width of the convex-shaped identification unit 16 whose size A is not smaller than the relative position and the cross-sectional width dimension of the identification surface layer 30 are not larger than the cross-sectional width of the convex-shaped identification unit 16 of the relative position. The maximum size C2; and the above identification surface 30 can be The word (including a single word), or a number (including a single number), or a pattern, or a symbol, etc., is optimal, and the identification surface layer 30 is attached by a bronzing method, or a branding method, or a transfer method, or a screen printing method.

On the trim 3 (such as Figures 1, 3, and 4), the surface of the flexible thin metal member 3 having the identification surface layer 30 is aligned and oriented toward the mold body 1 (i.e., the male mold or the female The identification unit 16 of the inner mold base 15 of the recessed area 10 of the mold (ie, the identification surface layer 30 is aligned and placed on the identification unit 16), and the terminal (not shown) of the static electricity generator (not shown) is used. Provided behind the inner mold base 15, so that the flexible thin metal member 3 can be surely adsorbed to the inner mold base 15 surface and covering the surface of the recessed identification unit 16, the interior of the semi-solid billet 20 to be thermally melted is subjected to a continuous supply of supply gas, so that the billet 20 is maintained to be expanded and expanded (eg, Figures 5 and 6). At this time, after the expansion blank 20 is clamped and pressed by the closing action of the mold body 1 (ie, the male and female molds), the injection tube 4 already located in the mold body 1 can be reused (ie, The conventional technique is directly inserted into the expanded billet 20 which has been pressed by the mold body 1 so that the pressurized gas can be continuously injected from the injection tube 4 and the hot melted semi-solid expanded billet 20 will be attached first. After the inner surface of the mold body 1 and the surface of the flexible thin member 3 are combined, at this time, since the cross-sectional width dimension A of the identification surface layer 30 is not larger than the maximum cross-sectional width of the concave-shaped identification unit 16 of the relative position, The dimension B1 and the identification surface layer 30 are also not smaller than the minimum dimension B2 of the cross-sectional width of the recessed identification unit 16 at the relative position, and the flexible thin member 3 having the identification surface layer 30 is recessed. The recognition unit 16 maintains a certain spatial distance between each other, so The injected pressurized gas is first pressed by the heat-fusible semi-solid expanded billet 20 to the flexible thin member 3 having the circumferential side of the surface layer 30 (i.e., the flexible thin member 3 located on the circumferential side of the recessed identification unit 16). After that, the identification surface layer 30 of the hot-melt semi-solid expanded billet 20 and the flexible thin decorative member 3 is further moved to the inside of the recessed identification unit 16 until the surface layer 30 is stretched and stretched and closely adhered.

The maximum dimension B1 of the cross-sectional width of the recessed identification unit 16 which is not larger than the relative position and the cross-sectional width dimension of the identification surface layer 30 are not smaller than the minimum dimension of the cross-sectional width of the recessed identification unit 16 of the relative position. B2, or the minimum dimension C1 of the cross-sectional width of the convex-shaped identification unit 16 in which the cross-sectional width dimension A of the identification surface layer 30 is not smaller than the relative position, and the cross-sectional width dimension of the identification surface layer 30 are not larger than the relative position. The maximum dimension C2 of the cross-sectional width of the convex shape identifying unit 16 is such that the identification surface layer 30 of the flexible thin decorative member 3 is stretch-stretched and deformed by using the thermally fusible expanded embryo 20 already located in the mold body 1. After the cooling, the finished product 2 is formed, and the surface of the finished product 2 is adhered with a three-dimensional identification surface layer 30, so that the contour of the identification surface layer 30 is convex or concave. The three-dimensional display can increase the clarity and recognition of patterns or characters, and at the same time, it can also display at least three color combinations on the outer surface of the finished product 2 to increase its color variability and vibrancy. Increase their purchasing desire and market share.
