TWI238113B - An internally label-sticking mold - Google Patents

Abstract

An internally label-sticking mold includes an outer mold and an inner mold. The outer mold has an interior hollow, for containing a shaped material and the inner mold, and the inner mold has an interior hollow for containing a label therein. Thus, when the outer mold with the shaped material placed in its interior hollow is combined with the inner mold with the label placed in its interior hollow for blowing and molding a plastic product, the shaped material becomes a finished plastic product stuck with a label integral.

Description

1238113 V. Description of the invention (1) [Technical field of invention patent] Especially refers to a combination of a mother mold and a child mold of an in-mold labeling mold made of plastic, the present invention is about hollow molding, and the surface of the hollow blow molding product is used to In-mold labeling mold with integrated label. [Previous technology] According to the currently marketed hollow molded plastic products, such as plastic containers such as plastic containers, the molding methods used are divided into two types. T) Plastic 4-type method is to inject the molding embryo (as shown in Figure 1, the molding die B (as shown in Figure 2)) = into: open the blow molding machine, you can install into various shapes according to the shape of the molding slot " Hollow molded plastic products. 0 The second method is to directly show the plastic raw material C in the molding die groove D0, and then from 2 ;; ^ (as shown in Figure 2 can be made into hollow molded products. Two machines 11 people milk Molding, that is, the plastic product made by the above-mentioned method, the content of a product E. If the commercial product t is clearly unplasticized in the plastic product E: filling the content, β 'mineral water, etc., all of you will be provided with vitamins. In the P Tai object process, the outer surface of the plastic product E is retracted. The thin film F is sleeved on the plastic product E and the heat shrinkable film F is contracted and bound to the plastic ^ Ε # 以 温 方

However, since this kind of heat shrinkable film F is outside the plastic product, and the knife 20,000 type 7 shrinks with the beam temperature; or the second film ^ 1 plastic product E will be lowered when placed in a low temperature environment, that is, the shrinkable film is closed. Suspension, disengagement, and failure of a plastic product E, resulting in the user's looseness, and the labeling of plastic products

Page 5 1238113 V. The description of the invention is this label (receive the case. [In the invention, the cost of the air-moulding combined with the cost of the hair (2) 'The hair shrinks the film.] The mother and child Mingzhe special needle can not completely blow mold the current problem of hollow combination. Research on plastic products and 'is invented is to provide-a type that can be integrated into a label and plastic at the same time, so that the label and plastic products in the Chinese product charging In the part mold slot, the rubber product and the label 1 · The present invention sets a mother mold and a child mold to make the standard], in order to make the following: six to ten hollow into a plurality of slots 1 1 and clamp the mother mold in the raw material and the child Mold combination, that is, [the implementation method shows that if the mother mold 1 of the present invention has a mother mold 3 and inserts the raw materials, the points are as follows: a molding die core with a molding die groove formed by the combined body molding can be used as a groove , Can be used for signing plastic labels and plastic labels. Tools, including pre-positioned plastic products, pre-placed child products, plastic molds, child molds, and child molds, and integrally molded mother products. The inspector can fully understand the present invention. One is the mold mold package module 10 ′ and the mother mold. The original 3 is for injection of the present invention and includes a mother mold ′. When it is a molding embryo, example (1), 1 and the sub-mold module 10 are knotted into the inlet 12, and the molding embryo is injected into the raw material. The child of the mold 3 can insert the plastic mold. The sub-mold is shown in the figure below. Indicating, 2, where the shape after the combination can be used as raw materials;

1238113 V. Description of the invention (3) Before the mold groove 11 is shown, it is appropriately added to blow molding with a hollow blow molding machine). The structure of the sub-mold 2 and the sub-mold 2 is also set up; or it is composed of a plurality of modules. The driving element for the up and down movement of the mold 2 is a hydraulic cylinder; or a pneumatic cylinder; or a screw driven by an electric horse. The driving element is provided with a sliding groove 210 (the module 22 of the sub-mold 2 is provided in the lower mold base 21. The slide groove set in the aforementioned lower mold base 21 is operated according to a certain track; a sub-mold system is also provided with plastic The shape of the product 3 0 The inner wall 2 3 〇 The setting ring 2 3 1 is used to restrict the label to the sub-mold of the sub-embodiment (~). The plural number 2 can be used with various shapes of plastic products 3 The driving element 2 2 1 (This drive element thinks that “of course, other appropriate power can be opened and closed” to facilitate taking out various shapes). In this way, in this embodiment (a), the module 10 of the mother mold 1 is turned off at the child mold slot 2 3 of the child mold 2 so that the material can be softened slightly, so that the plastic product 3 0 (see FIG. 8) One can be made according to the shape of the plastic product. And the sub-mold 2 includes a driving element 20, and the driving element 20 can be a screw that can move up to f; or the hydraulic motor 20 is fixed with the lower mold base 21, such as As shown in Figures 9 and 11), the module 2 2 is provided with a slider 2 2 0 2 10 to make the module 2 2 open, the groove 2 3, and the shape of the sub mold groove 23, and The circumference of the mold slot 2 3 is 2 3 1. This label 4 sets the insertion depth of the ring mold slot 23. In order to remove the plurality of modules 20, the module 22 is a hydraulic cylinder on the side of the module 22; or the most logical component of the pneumatic cylinder is used to drive the module 2 2 plastic products 3 0 (see Figure 7 and The eight mother molds can be inserted into the raw material embryo 3 in advance, and the label 4 can be placed in advance. This mold moves, and the child mold 2 is simultaneously inserted.

Page 7 1238113 V. Description of the invention ^ One ~-Drive 2 f 2 0 to push up into the female mold slot 母 of the female mold 1 until the raw material embryo = is blown by the blow tube 5 (see Figures 7 and 8) (Shown), then the plastic product 3 can be integrated into the standard, and then the child mold 2 is separated from the mother mold 1 $ ff1 1 1 and each module 2 2 of the child mold 2 is driven by the driving element ^ 1 After opening, the formed plastic product 30 can be taken out. In this way, the plastic product 30 can be completely combined with the label 4 and the value of the plastic product can be enhanced. As shown in Figures twelve to fourteen, the embodiments (two) and (three and three) of the present invention are derived from the foregoing embodiment (one), as shown in the figure. Slot ② Example (2), (3), and (4) The child mold 2 is provided with a plurality of = s 2 3 so that a plurality of plastic products 30 can be molded at one time, which also has the same structural effect as implemented. Sun Six ^ As shown in Figures 15 and 16, the embodiment (five) of the present invention is also derived from the embodiment (a). The figure shows the module of the child mold 2 of the embodiment of the present invention. 2 2 A is integrally formed, and is provided with a sub-mold 2 ′ but without a driving element 2 2 1 to match the plastic product 30 y with the same structural effect as in the embodiment (1). As shown in Figs. 17 to 23, this is an embodiment (six) of the present invention. The hollow molding mold of this embodiment (six) includes a mother mold 1 抡 1 = ϋ1 ', where the mother mold 1 is provided with a plurality of modules 1 〇, and the complex mold ϊ Γ is formed with a master mold slot 11 and the master mold slot 11 is provided with an injection
