Description
Technical field
The utility model belongs to technical field of mold, refers in particular to a kind of disposable syringe overcoat mould.
Background technology
The outer mold of the general at present disposable syringe that uses, shown in Fig. 1-2: be provided with several syringe jacket die cavities 11 in mould 10 inside, charging aperture 12 is communicated with each syringe jacket die cavity 11 respectively by the cold runner 13 in the mould 10, this class mould 10 exists the some shortcomings part: syringe jacket is when injection mo(u)lding, material injects by the cold runner in the mould 10 13 from charging aperture 12 and imports syringe jacket die cavity 11, material on the cold runner 13 in syringe jacket die cavity 11 cooling formings in mould 10 in the mould 10 and then becomes waste material after the cooling, wastage of material is serious when the moulding syringe jacket like this, the rate that generally wastes raw material arrives 30%, and the production cost improves.
Summary of the invention
The purpose of this utility model provides a kind of disposable syringe overcoat hot runner mould that the syringe jacket wastage of material is few, production cost is low of producing.
The purpose of this utility model is achieved in that
Disposable syringe overcoat mould, top at mould is provided with charging aperture, be provided with several syringe jacket die cavities at mould inside, charging aperture is communicated with each syringe jacket die cavity respectively by runner, below charging aperture, be provided with the runner heating plate, on the runner heating plate, be provided with some hot flow path branches, be provided with several discharging openings in the end of each hot flow path branch, each discharging opening docks with the injection moulding import of the syringe jacket die cavity of mould respectively, and described charging aperture is respectively by the runner heating plate, hot flow path branch and discharging opening are communicated with the syringe jacket die cavity.
Be respectively equipped with two sprues that are communicated with charging aperture in the above-mentioned runner heating plate, on every sprue, be respectively equipped with six branch flow passages.
Above-mentioned being provided with some hot flow path branches on the runner heating plate be: be provided with 12 hot flow path branches that match with it on every branch flow passage at the runner heating plate.
The above-mentioned end in each hot flow path branch is provided with several discharging openings: be provided with four discharging openings in the end of each hot flow path branch.
Above-mentioned discharging opening docks with the injection moulding import of the syringe jacket die cavity of mould respectively: syringe jacket die cavity bottom and the syringe jacket die cavity below the discharging opening are provided with step, and discharging opening docks with the injection moulding import of the syringe jacket die cavity of mould on side stage rank of syringe jacket die cavity bottom respectively.
The outstanding compared to existing technology advantage of the utility model is:
The utility model is provided with the runner heating plate below charging aperture, the runner heating plate is provided with hot flow path branch, end in hot flow path branch is provided with discharging opening, each discharging opening is aimed at a side of syringe jacket die cavity bottom, syringe jacket is when injection mo(u)lding, do not have cold runner in the mould, wastage of material is few when causing producing syringe jacket, production cost is low.
