[0002] There are many types of molds at present, one of which is to manufacture plastic raw materials, that is, injection molds. After the injection molding is completed, when the flat rubber mouth is ejected, there will be residual material on the injection molded parts, which is the nozzle material. At this time, manpower is required. It is easy to produce burrs after breaking and separating and manual separation, which often requires manpower for secondary processing, which is easy to form burrs, which is time-consuming and labor-intensive, which increases the cost, and the operation is complicated, the work efficiency is low, and the removal of the nozzle material cannot effectively ensure the balance of all angles , affecting product quality and production efficiency

The invention discloses a male mold centre type internal cutting mold, comprising an upper fixed plate, a lower fixed plate, support blocks, a female template arranged on the upper fixed plate and a male template arranged on the lower fixed plate. The male template is provided with a core insert for the injection molding of the product, and the female template is provided with a cavity insert matched with the core insert. The core insert is provided with a mold cavity for the injection molding moulding and a stub bar groove communicated with the mold cavity, top plates are arranged in the two support blocks, top pin fixed plates are arranged on the top plates, and finished ejector pins are fixed on the top pin fixed plates. Centres are fixed on the top plates, and an ejector capable of driving the top plates to move is arranged on the lower fixed plate. Compared with the manual cutting, by arranging a gel-ejecting port on the product appearance, the mold of the invention achieves smooth surface of the product appearance with arrangement of a rubber ejecting port, and is not easy to generate rough edges. The mold of the invention has high efficiency, saves the labor and cutting time, and avoids the generation of the rough edges on the products. The mold of the invention has simple operation and convenient use, enhances the product quality and the production efficiency, and achieves the purpose of cutting the residual stub bar automatically.
Description
technical field [0001] The invention relates to a mold for injection molding parts, in particular to an in-cutting mold of a male die and thimble for cutting excess nozzle material of the injection molding parts. Background technique [0002] There are many types of molds at present, one of which is to manufacture plastic raw materials, that is, injection molds. After the injection molding is completed, when the flat rubber mouth is ejected, there will be residual material on the injection molded parts, which is the nozzle material. At this time, manpower is required. It is easy to produce burrs after breaking and separating and manual separation, which often requires manpower for secondary processing, which is easy to form burrs, which is time-consuming and laborious, which increases the cost, and the operation is complicated, the work efficiency is low, and the removal of the nozzle material cannot effectively ensure the balance of all angles , affecting product quality a...
