Description

Small-size display screen framework injection mold Technical Field The utility model relates to the field of injection molding of small display screen frames, in particular to an injection mold for a small display screen frame. Background In the injection molding process, the structural design of the mold has important influence on the quality and the production efficiency of the product. The injection mold of the small part usually adopts a single pouring channel or a central pouring mode, and the thin-wall frame products are easy to deform, shrink or have surface defects due to uneven filling or insufficient cooling. In order to improve the molding quality of the thin-wall frame product, a part of the molds are designed to be small-sized multiple pouring channels, but the uneven filling pressure can be caused by unreasonable pouring channel arrangement, so that the appearance of the product is affected. Disclosure of utility model In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: The utility model provides a small-size display screen framework injection mold, includes the movable mould group that sets up fixed mould group and top in the bottom, movable mould group comprises cope match-plate pattern, locating plate and the movable mould board that top-down set gradually, and first die cavity is located the movable mould board downside, still be provided with on the movable mould board be used for the pouring pipe that links to each other with the injection molding machine, the pouring pipe through first runner and second runner to the injecting glue in the first die cavity, first runner with the second runner cross intercommunication, the pouring pipe is located first runner with the intersection department that the second was watered. Further, the pouring pipe is located at the center of the movable die plate, and the first pouring channel and the second pouring channel are respectively connected to four corners of the first die cavity. Further, a mold closing positioning block is arranged on the movable mold plate. Further, a first guide post extending downwards is arranged on the upper template, and the first guide post penetrates through the positioning plate and the movable template to be inserted into the fixed die set. Further, an injection molding machine locating ring is arranged at the top of the upper template, and the pouring pipe penetrates through the center of the injection molding machine locating ring and is connected with the injection molding machine. Further, a second guide post which reversely penetrates into the movable module is arranged in the fixed module. The utility model has the beneficial effects that: According to the small display screen frame injection mold provided by the utility model, through corner injection molding and double pouring channel design, the molding quality and the production efficiency of a thin-wall frame product are improved.
