[0003] None of the above methods can ensure that the edge of the IMD decorative sheet can completely cover the formed base material, and the arc cannot be made more than a quarter of a circle, otherwise, undercuts will occur
If the rounded corner of the edge of the IMD decorative sheet has an undercut, when covering the base material, the existing ordinary mold cannot realize it

Embodiment Construction
[0028] In order to understand the technical features, objects and effects of the present invention, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[0029] Such as figure 1 , figure 2 As shown, a vacuum adsorption fixing of the present invention is immunized to realize the injection molded mold including the IMD decorative sheet including the front mold 1, the rear mold 2, and the slider mechanism 3.
[0030] Combine Figures 2 to 5 As shown, the front mold 1 is provided with the positioning region 11 placed on the rear molded sheet 4, and the positioning region 11 is concave in the front mold 1, and the decorative circle is provided with a curved circle. Corner edge 41.
[0031] In the present embodiment, the rounded edge 41 of the decorative sheet 4 is retrofitted with respect to the body portion of the decorative sheet 4, and when the formation is placed, the replus portion of the rounded edge 41 will be o...

The invention relates to a mold for realizing in-mold injection molding of an IMD decorative sheet through vacuum adsorption and fixation. The edge of the decorative sheet is provided with an arc-shaped rounded corner covered edge, and a front mold, a rear mold and a sliding block mechanism are included; a positioning area for containing the formed decorative sheet is arranged at the opposite sides of the front mold and the rear mold; the positioning area is internally recessed in the front mold and is provided with an adsorption mechanism for adsorbing and positioning the decorative sheet; the sliding block mechanism comprises a side slide block which can be mounted on the rear mold in a lateral sliding manner; a pressing part is arranged at the end, opposite to the positioning area, of the side slide block, after the side slide block is close to the positioning area, the pressing part is matched with the edge of the positioning area to form a rounded corner forming covered edge matched with the covered edge in shape, the covered edge at the edge of the decorative sheet is positioned, and a parting line of the rounded corner covered edge is located at the edge combination positionof the pressing part and the positioning area; and a cavity for forming a base material is formed between the decorative sheet and the rear mold, so that the base material is formed and adhered to the back surface of a membrane. Rubber material filling and subsequent demolding of the inverted buckling position are not influenced, and the diversified appearance requirements of the decorative sheetare met.
Description
Technical field [0001] The present invention relates to a molding mold, and more particularly to a mold in which IMD decorative sheet is immode molded in a vacuum adsorption. Background technique [0002] When the substrate is formed on the back of the IMD decoration sheet, the radius of the edge of the IMD decorative sheet is small, so that the IMD decorative sheet can be placed in the mold cavity, and the edge does not extend the cavity, or the IMD decoration sheet. The rounded outer edge of the edge extends outward, and after molding, the portion will be cut off again. [0003] The above methods do not guarantee the edge of the IMD decorative sheet to cover the formed substrate, and the radians cannot be done more than one-quarter circle, otherwise, the buckle will be generated. To make the fillet of the edge of the IMD decorative sheets have a buckle, when the substrate is covered, the existing common molds cannot be achieved. Inventive content [0004] The technical problem...
