The invention relates to the technical field of molds, in particular to an
oil tank front decorating part mold which comprises an upper mold body and a lower mold body, mold cavities are formed in the upper mold body and the lower mold body, the mold cavities in the upper mold body and the lower mold body are correspondingly arranged and communicate with each other, an excess material cavity is formed in the middle of each mold cavity, and the excess material cavity is formed between the two mold cavities. The excess material cavity is communicated with the mold cavities on the two sides, the upper mold is provided with an injection molding
pipe corresponding to the excess material cavity, the bottom of the injection molding
pipe is fixedly provided with a
cutting plate, the
cutting plate is arranged corresponding to the position and shape of the excess material cavity, the injection molding
pipe is slidably connected with the upper mold, and the injection molding pipe can drive the
cutting plate to move towards the excess material cavity. And a cutting blade is arranged at the edge of the cutting plate. The die cavities of the upper die and the lower die are correspondingly communicated and can be used for forming the
oil tank front decorating part, and the excess material cavity is formed between the two die cavities and communicated with the die cavities so that excess materials can be conveniently collected. The injection molding pipe is used for injecting materials and can drive the cutting plate to move towards the excess material cavity, the cutting blade on the edge of the cutting plate can
cut the materials between the excess material cavity and the mold cavity at
proper time, the excess materials in the excess material cavity can be
cut after injection molding is completed and waiting for forming, and secondary cutting does not need to be carried out after the excess materials are taken out. And the
machining efficiency and the overall production efficiency can be improved to a certain extent.
