Problems solved by technology
The glue will make the cover cloth sag in the injection molded plastic parts, which not only affects the appearance, but also makes the resonance effect of the cover cloth poor, which affects the product quality
The existing in-mold cloth can only realize the injection molding of plastic parts smaller than a semicircle, and cannot realize the cloth injection molding of the injection plastic parts larger than a semicircle. When making a mold, the molds of the same type will be opened sequentially, and the effect of opening the molds at the same time cannot be achieved

The invention relates to the technical field of intra-mold cloth wrapping, in particular to a plastic shell intra-mold cloth wrapping device. A sliding upper mold is an inverted-circular-truncated-cone-shaped sliding mold, the sliding upper mold is fixedly connected with a first upper mold, mold rear sliding blocks are fixedly mounted on the side wall of the sliding upper mold, profiling upper molds are arranged on the lower surface of a second upper mold, pressing plates are arranged on limiting molds, the mold rear sliding blocks are slidingly connected with the profiling upper molds, limiting sliding blocks are fixedly mounted on a first lower mold, a profiling lower mold is arranged on a second lower mold, the limiting sliding blocks penetrate through the second lower mold to be slidingly connected with the limiting molds, and a push assembly penetrates through the first lower mold to abut against the second lower mold. As an injection cavity is formed by the profiling upper molds,the profiling lower mold and the limiting molds jointly, an injection molding plastic part with a forming shell larger than a semi-circle can be subjected to injection molding, the injection moldingplastic part can be conveniently taken out, the process of bonding wrapping cloth is omitted, bonding is firm, and the phenomenon of local looseness is not generated.
Description
technical field [0001] The invention relates to the technical field of in-mold cloth wrapping, in particular to a plastic casing mold inner cloth wrapping device. Background technique [0002] Nowadays, the surface of many plastic shells needs to be covered with a layer of cloth. The conventional method is to inject the plastic parts first, and then use glue to bond the cloth and the injection molded plastic parts together through secondary processing. The glue will cause the cover cloth to sag in the injection molded plastic parts, which not only affects the appearance, but also makes the cover cloth have poor resonance effect and affects the product quality. The existing in-mold cloth can only realize the injection molding of plastic parts smaller than a semicircle, and the injection molding of plastic parts larger than a semicircle cannot be realized. When making a mold, the molds of the same type will be opened sequentially, and the effect of opening the molds at the sa...
