Manufacturing hollow blow box identification layer device

This creation belongs to the technical field of manufacturing a hollow blow box identification layer device.

According to the conventional hollow blow tool box process, the process includes at least: (A) blanking and expanding billet: the heated and melted semi-solid thermoplastic material is extruded from the die and the center of the die continues downward. 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 cut expanded billet until the molten semi-solid expanded billet completely conforms to the surface of the male and female molds; (D) cooling molding: using the cooling flow channel inside the mold to make the molten semi-solid expansion The billet begins to cool and solidify; (E) the finished product: the male and female molds are separated from the mold, 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. Improve, and make it perfect and practical; plus, the creators have experienced countless After updating the experimental test and summarizing the feedback on the actual operation of the consumer, I found that the following problems still need to be further improved:

1. Since the material of the general air blowing tool box is mainly made of monochrome PE plastic material, and the molding, the brand name and the plastic box of the customer are also completed at the same time, so that the formed tool box is only in a single color. Therefore, it is not a big problem for the consumer to immediately and clearly identify the customer's brand trademark.

2. In order to improve the above-mentioned defects, the manufacturer will attach the color of the formed tool box to the customer's brand trademark by means of secondary processing (such as screen printing, etc.) to temporarily solve the above-mentioned lack of the traditional manufacturing method. The oil stains touched by the place or the smashing or scratching caused by the moving movement will cause the color layer of the surface to fade or be removed.

3. As mentioned above, although the screen printing process enables the top surface of the tool box to achieve multi-color recognition, the bottom surface formed between adjacent ribs is still unable to achieve multi-color by screen printing. The effect of identification is another major problem for the industry and a problem that needs to be solved.

4. In order to improve the above-mentioned deficiencies, the manufacturer has applied for the approval certificate No. M397891 "The structure of the surface layer of the hollow blow box", which is to combine the synthetic parts of synthetic leather or leather or cloth to fuse. Semi-solid expansion of the billet to form a finished product; however, since the thermal expansion rate or shrinkage ratio of the synthetic leather or leather or cloth is different from that of the expanded billet, the joint surface of the two different materials cannot be formed. 100% cut or aligned, As a result, it is considered to be a defective product at the time of manufacture, and at the same time, the defective product cannot be directly pulverized and recycled, and the manufacturing cost is greatly increased.

In view of this, the present invention proposes a device for manufacturing a hollow blow box identification layer in order to effectively overcome the above problems in order to benefit all consumers and manufacturers in view of the above-mentioned shortcomings of the prior art.

The main content of the hollow blow box identification layer device of the present invention is to provide a plurality of suction air passages through a fixed area already located on the mother mold, and the suction air passage system can be used as a fixed area to the air suction device. The gas flow is connected so that the extended and impervious thin objects can be attracted to the fixed area by the suction of the suction air passage, so that they can be melted and semi-solid during the molding process. The forming and extrusion of the expanded billet causes the thin object to move with it, but is subject to the self-heating of the expanded billet and the compression of the pressurized gas therein, so that it is closely attached to the molten semi-solid expanded embryo. The thin object on the material produces surface melting and bonding, and the thin object can be stretched and stretched as the molten semi-solid expanded billet is forced into the inner groove by the pressing gas. In order to ensure that the bonding between the thin object and the expanded billet is more tight, it can overcome the trouble that the conventional structure is separated by easy impact, and at the same time, the surface of the blown box after forming can be formed into knowledge. Layer, in particular, the discriminating layer can be located at the top surface of the blow box, at the surface or at times of high blow box or blow located The bottom surface between the adjacent convex strips of the box to prevent the scratching or scratching caused by the impact of external force, and to help the consumer to quickly identify when purchasing, to increase the product identification warranty period for its progress The idea of sex.

In addition, this creation uses thin materials made of the same quality as the thermoplastic plastic expanded billet (such as PP, or PE, or PET, or a mixture of PP and PE) to ensure thinness. The defective product produced by the fusion of the object and the expanded billet can be directly recovered and pulverized and reused, so as to greatly improve the recycling rate and reduce the manufacturing cost thereof, which is another progressive claim.
