Abstract
A glue leakage-proof device for a preform-casting mould nozzle comprises a mould cavity, wherein the mould cavity is internally provided with a die cavity; one end of the mould cavity is connected with an installation base; the mould cavity and the installation base are internally provided with mould cores; the other end of the mould cavity is provided with a material injection hole; the material injection hole is communicated with the die cavity; the mould cavity is connected with a nozzle base; the nozzle base is internally provided with the nozzle; the nozzle is provided with a nozzle hole; the nozzle hole is communicated with the material injection hole and internally provided with a valve needle; and one end of the valve needle is inserted into the material injection hole through the nozzle. The glue leakage-proof device is characterized in that the joint position of the nozzle with the bottom of the mould cavity is provided with a temperature-resistance sealing gasket so as to improve the sealing property at the connection part of the nozzle and the mould cavity, prevent glue leakage in the process of injection molding and balance the heat energy loss of the nozzle and the material injection hole due to cooling; when the nozzle is closed, the temperature of the material injection hole is required to be low so as to solidify melt glue; and the temperature-resistance sealing gasket can reduce the heat energy transmitted into the mould cavity, therefore, the attractive appearance of a bottle preform is remained and the rejection rate of the product is reduced.
Description
Technical field
The utility model relates to annotates embryo mould nozzle leakproof adhesive dispenser, belongs to the plastics machinery technical field.
Background technology
Annotate the embryo mould and in the material feeding process, inject die cavity by the gluey plastics that nozzle and material hole melt heat, after finishing, material feeding blocks material hole by needle again, anti-leak-stopping glue, but the nozzle of notes embryo mould and die cavity are for heat-resisting, long service life, all be made, and directly contact between metal and the metal that its sealing is relatively poor with hard metal material, when annotating the material feeding of embryo mould, the part material can be extruded to produce from the slit and leak glue.And the temperature of hot flow path nozzle just determines the quality of cast gate and directly influences the processing technology of product, each nozzle under stable state temperature fluctuation and the temperature difference between the nozzle, all can have influence on the quality of formed product quality.If nozzle temperature too high meeting hydrostomia or wire drawing, crossing low melten gel can be cold fixed.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming that prior art exists, provide a kind of joining place that the leakproof adhesive dispenser is set at nozzle and cavity bottom, improve the sealing property between nozzle and the die cavity, and can make temperature keep the notes embryo mould nozzle leakproof adhesive dispenser of balance.
The technical scheme that the utility model is annotated embryo mould nozzle leakproof adhesive dispenser is: comprise die cavity, die sinking chamber in the die cavity, one of die cavity is connected and installed seat, in die cavity and mount pad, core is set, other end at die cavity is shaped on material hole, material hole communicates with die cavity, die cavity is connected with the nozzle seat, in the nozzle seat nozzle is installed, is opened the nozzle hole in the nozzle, the nozzle hole communicates with material hole, in the nozzle hole, be equipped with needle, one of needle inserts in the material hole by nozzle, it is characterized in that the joining place of described nozzle and cavity bottom is equipped with the heatproof sealing gasket, heatproof sealing gasket and nozzle, material hole and needle contact.
The utility model discloses a kind of notes embryo mould nozzle leakproof adhesive dispenser, at nozzle and cavity bottom joining place the heatproof sealing gasket is installed, improve the sealing property between nozzle and the die cavity junction, in injection moulding process, can effectively prevent leak-stopping glue, and the heat of taking away because of cooling between effective balance nozzle of energy and the material hole, when nozzle is closed, then require the temperature of material hole low to making melten gel fixed, the heatproof sealing gasket can reduce heat and be delivered in the die cavity, keep the aesthetic in appearance of bottle embryo, reduce the scrappage of product.
The utility model is annotated embryo mould nozzle leakproof adhesive dispenser, is connected by bolted joint between described die cavity and the mount pad.Bolted joint is connected and installed convenience, reliable.Described heatproof sealing gasket is made by the polyester material.High temperature resistant polyester material heat resistance is good, and long service life contacts good airproof performance with metal material.
Description of drawings
Fig. 1 is that the utility model is annotated embryo mould nozzle leakproof adhesive dispenser structural representation;
Fig. 2 is the local enlarged diagram in A place of Fig. 1.
The specific embodiment
The utility model relates to a kind of notes embryo mould nozzle leakproof adhesive dispenser, as Fig. 1-shown in Figure 2, comprise die cavity 4, die sinking chamber 41 in the die cavity, one of die cavity is connected and installed seat 2, core 1 is set in die cavity 4 and mount pad, be shaped on material hole 43 in the other end of die cavity, material hole communicates with die cavity 41, die cavity is connected with nozzle seat 7, nozzle 6 is installed in the nozzle seat, is opened the nozzle hole in the nozzle, the nozzle hole communicates with material hole 43, in the nozzle hole, be equipped with needle 9, one of needle is passed through in the nozzle 6 insertion material holes 43, it is characterized in that the described nozzle 6 and the joining place of die cavity 4 bottoms are equipped with heatproof sealing gasket 5, heatproof sealing gasket 5 and nozzle 6, material hole 43 and needle 9 contact.At nozzle 6 and die cavity 4 bottom joining places heatproof sealing gasket 5 is installed, improve the sealing property between nozzle 6 and die cavity 4 junctions, in injection moulding process, can effectively prevent leak-stopping glue, and the heat of taking away because of cooling between effective balance nozzle 6 of energy and the material hole 43, when nozzle is closed, then require the temperature of material hole 43 low to making melten gel fixed, heatproof sealing gasket 5 can reduce heat and be delivered in the die cavity 4, keeps the aesthetic in appearance of bottle embryo, reduces the scrappage of product.Be connected by bolted joint 3 between described die cavity 4 and the mount pad 2.Bolted joint 3 is connected and installed convenience, reliable.Described heatproof sealing gasket 5 is made by the polyester material.High temperature resistant polyester material heat resistance is good, and long service life contacts good airproof performance with metal material.
