Abstract
The utility model discloses an improved injection mold for an exhaust vent. The improved injection mold comprises a movable mold, a fixed mold, a movable mold seat plate, a fixed mold seat plate, a positioning ring, a material pull rod, a pouring gate, an injection runner, a molded cavity, the exhaust vent, an exhaust passage and a cylinder valve, wherein the positioning ring is fixedly arranged above the movable mold seat plate; the movable mold is fixedly arranged below the movable mold seat plate; the fixed mold is fixedly arranged above the fixed mold seat plate; the movable mold is arranged above the fixed mold; the pouring gate is positioned above the positioning ring; the lower end of the injection runner is positioned above the fixed mold; the molded cavity is connected with the injection runner; the exhaust vent is led to the atmosphere; the exhaust passage is connected with the exhaust vent and the molded cavity; the cylinder valve is arranged at a joint of the exhaust passage and the molded cavity. The improved injection mold for the exhaust vent can enable an injection-molded piece to be well demolded, so that the quality of the injection-molded piece can be improved.
Description
Technical field
The utility model relates to injection mould processing technical field, is specifically related to a kind of steam vent improved injection mould.
Background technology
For improving the injection moulding efficiency of hot melt material, conventionally in the forming cavity of injection mold, arrange and be communicated with extraneous steam vent, steam vent diameter is too small usually there is exhaust not in time or situation about having some setbacks, thereby causes moulding to produce the flaws such as bubble; And the excessive steam vent that can produce of steam vent is connected the situation that is difficult to the demoulding with moulding, for different situations, need in conjunction with the self structure feature of mould, design different steam vents to address the above problem.
Summary of the invention
The purpose of this utility model is to provide a kind of steam vent improved injection mould, can discharge well the air in the forming cavity of injection mold, and can make moulding realize well the demoulding, thereby improve the quality of moulding.
To achieve these goals, the technical scheme the utility model proposes is:
A kind of steam vent improved injection mould, comprise dynamic model, cover half, Bottom clamp plate, top clamping plate, centring ring, sprue puller, pouring slot, beam road, die cavity, steam vent, exhaust duct, cylinder valve, described centring ring is fixedly arranged on described Bottom clamp plate top, described dynamic model is fixedly arranged on described Bottom clamp plate below, described cover half is fixedly arranged on described top clamping plate top, described dynamic model is arranged at described cover half top, described pouring slot is positioned at the top of described centring ring, upper end, described beam road connects described pouring slot, lower end, described beam road is through described centring ring, described Bottom clamp plate and described dynamic model, the lower end in described beam road is positioned at described cover half top, described die cavity connects described beam road, described steam vent leads to atmosphere, and described exhaust duct connects described steam vent and described die cavity, and described cylinder valve is arranged at the tie point place of described exhaust duct and described die cavity.
As the further improved steam vent improved injection mould of the utility model, described exhaust duct is positioned at the intersection of described dynamic model and described cover half, and described steam vent is parallel with described beam road, and described steam vent upper end goes out open height and is not less than described pouring slot.
As the further improved steam vent improved injection mould of the utility model, the closed cavity that forms of described cover half and described top clamping plate, described cylinder valve is arranged in described cavity, and described cover half is provided with the air valve groove that moves and connect described exhaust duct for described cylinder valve piston rod.
Steam vent improved injection mould provided by the utility model, can discharge well the air in the forming cavity of injection mold, and can make moulding realize well the demoulding, thereby improves the quality of moulding.
