Abstract

The invention discloses a bottom injection mould. The bottom injection mould comprises a bottom plate, guide column guide sleeves, a lower template, an upper template, a top plate, inserting pieces and exhaust openings. The guide column guide sleeves are arranged on the bottom plate, the bottom plate is provided with the lower template, the upper template is arranged on the lower template, the inserting pieces are arranged in the upper template, the upper template is provided with the top plate, and the exhaust openings are further formed in the upper end of the upper template. According to the mode, the bottom injection mould has the advantages of being high in reliable performance, precise in positioning, compact in structure, high in production speed, good in finished product quality, sufficient in material filling and the like, and meanwhile has the wide market prospect in the injection mould market.

Description

technical field [0001] The invention relates to the field of injection molds, in particular to a bottom injection mold. Background technique [0002] Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to injecting the heated and melted material into the mold cavity by high pressure, and after cooling and solidifying, a molded product is obtained. Existing injection molding is suitable for complex molds, but for some small holes, or thin-walled parts are prone to problems such as insufficient filling, which reduces the quality of injection molded parts. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a bottom injection mould, which can avoid injection cavity through bottom injection molding, has a simple structure and good injection quality; the injection molding quality can be guaranteed by setting a plug-in with a through hole and a low...
