Description
Technical field:
The utility model belongs to technical field of mold, refers in particular to a kind of thin-walled cutlery box injection mold.
Background technology:
Mould is used to the instrument of shaping material object, and different moulds is made up of different parts, in reality, produces some products and all be unable to do without mould.Thin-walled cutlery box is widely used in the occasions such as the packing of food.Thin-walled cutlery box is also manufactured by mould.Do not arrange cooling system in the counterdie of existing thin-walled cutlery box, cutlery box shaping rear cooling in die cavity is slow, affect the depanning time, and product easily has crude.Meanwhile, when depanning, because cutlery box forms the environment forming vacuum between lower mold core, the demoulding is more difficult.Moreover existing lower mold core and counterdie are splits, there is secondary operations, assembling trouble, and have error, cause injection mo(u)lding difficulty etc.
Summary of the invention:
The purpose of this utility model is to provide a kind of raising end product quality, depanning thin-walled cutlery box injection mold easily.
The utility model is achieved in that
Thin-walled cutlery box injection mold, include compound plate, runner plate, die cavity, core, lower compound plate, described die cavity is provided with more than one, correspondingly core is provided with more than one, die cavity and core form die cavity, upper compound plate is provided with runner hole, runner is provided with in runner plate, runner is connected with cast gate, cast gate is to injection moulding in die cavity, described lower compound plate and core are provided with the gas circuit of one or more, the gas circuit that the gas circuit on lower compound plate is corresponding on core is docked and connected, and the outlet of the gas circuit on core is positioned on the sidewall of insert.
In technique scheme, described core is provided with cooling duct, the import of cooling duct is arranged on the sidewall of core, and the insert of core is provided with the coolant flow channel be communicated with cooling duct.
In technique scheme, described runner includes sprue and the branch flow passage of one or more, and the outlet of each branch flow passage is connected to plural cast gate.
In technique scheme, the cast gate of described each die cavity is provided with two or more, and the outer edge respectively along die cavity top is arranged.
In technique scheme, described die cavity, core, branch flow passage are provided with four.
In technique scheme, described core and insert one-body molded.
The advantage that the utility model is given prominence to compared to existing technology is:
1, be provided with cooling water channel in core of the present utility model, substantially increase cooling effect, avoid and originally caused product there is crude defect because of cooling effect difference;
The sidewall of 2, insert of the present utility model is provided with the through hole be communicated with die cavity, for vacuum breaker between cutlery box and lower mold core, is convenient to depanning;
3, core of the present utility model and insert one-body molded, avoid originally needing to carry out secondary operations, without the need to assembling, reduce error.
