Description
Technical field
The utility model relates to a kind of valve, has been specifically related to a kind of rubber injection mold check valve.
Background technology
The method that plastic cement is shaped is a lot, but it is the most general with the use of injection molding method, especially in recent years for continuous research and the improvement of forming machine, by manual, semi-automatic and arrive and automatically changed, but the difference because of formed machining character, must there is various multi-form forming mill, to adapt to different working conditions, even if in the forming mill of same specification, also can be different because of the design of each producer, and form is different.
Generally, universal injection moulding machine basic structure comprises three major parts, i.e. ejecting device, close die device (lock mould and stripper apparatus) and hydrostatic transmission and electrical control system, wherein ejecting device is the cardiac component of injection moulding machine, its effect ensures timing, quantitatively heating material plasticizing and melting, then with certain pressure and faster speed the molten plastic being equivalent to a shot is injected in mold cavity, penetrate the complete melt also being had one period of dwell time to shrink because of cooling to supplement a part in die cavity, make goods closely knit and prevent material reflux in die cavity. therefore, ejecting device must ensure that plastics evenly plastify, and has enough injection pressure and dwell pressure.
These ejecting devices required can be met and mainly contain plunger tpe, plunger one screw, screw etc., wherein screw ejecting device, comprise injection moulding cylinder, injection moulding cylinder is communicated with hopper, screw rod 12 it is provided with in injection moulding cylinder, it is provided with cylinder 11 in the left side injection moulding cylinder of screw rod 12, as shown in Figure 2, when cylinder 11 place transported to by plastic cement by screw rod 12, when plastic cement amount reaches a certain amount of, screw rod 12 stops rotating, start cylinder 11, plastic cement is injected in mould by cylinder 11, and because screw rod 12 is adjacent with cylinder, cylinder is when extruding plastic cement, part plastic cement can be compressed on screw rod 12, and screw rod 12 is applied pressure, screw rod 12 is caused damage, reduce screw rod 12 work-ing life.
Practical novel content
The utility model is intended to provide a kind of rubber injection mold check valve increased work efficiency.
Rubber injection mold check valve in this scheme, comprise valve body, valve body is connected on injection moulding cylinder and is located between screw rod and cylinder, valve seat it is provided with in valve body, valve seat is provided with spool, and spool is connected with the valve rod through valve body, and the valve body below spool is hinged with symmetrical blocking material plate, two are equipped with elasticity part between blocking material plate and valve body, the length sum of two blocking material plates is greater than the bore of valve body.
Know-why and the useful effect of this scheme be: check valve place transported to by plastic cement by screw rod, and enter in valve body, by control valve rod, spool being separated with valve seat, and is opened by the opening of valve seat, plastic cement enters in the valve body below valve seat by opening, plastic cement contacts with two blocking material plates, and pressing blocking material plate swung downward, two blocking material plates do not contact with each other, and plastic cement flows in the injection moulding cylinder of valve body outside through two blocking material plates.
Then plastic cement enters in cylinder, start cylinder, plastic cement is injected in mould by cylinder, because cylinder is connected with valve body, so part plastic cement will have in squeezed inlet valve body, plastic cement contacts with two blocking material plates subsequently, two are equipped with elasticity part between blocking material plate and valve body, two blocking material plates will be kept certain height, now plastic cement will upwardly upwards swing by two blocking material plates, again because the length sum of two blocking material plates is greater than the bore of valve body, so two blocking material plates will contact with each other and offset, make to be closed below valve seat, therefore plastic cement can not contact with valve seat, more can not enter into above valve seat by the opening of valve seat, and pass through valve body, plastic cement is contacted with screw rod.
Compared with prior art, cylinder is when extruding plastic cement, and the setting of check valve, prevents part plastic cement to be compressed on screw rod, and makes plastic cement screw rod can not be applied reactive force, decrease the damage of screw rod, it is to increase the work-ing life of screw rod.
Further, between valve rod and valve body, it is provided with gasket, when valve rod makes spool be separated with valve seat, valve rod is relative to valve body or slip or rotates, gap between the two easily makes plastic cement flow out, and gasket can make to be formed between valve rod and valve body sealing, avoids plastic cement excessive in valve body.
Further, elasticity part is spring, and spring is a kind of mechanical component utilizing elasticity to carry out work, there is deformation in the part made with resilient material, again recovers original state after removing external force under external force, when cylinder stops extruding plastic cement, two blocking material plates, by the elastic force of spring, are easy to recover original state.
Further, the position of two blocking material plate symmetry axis is provided with projection, protruding between valve seat and blocking material plate, when two blocking material plates upwards swing, two blocking material plates and projection contacts, protruding setting, two blocking material plates can be made more easily by valve seat closed downwards so that plastic cement is more difficult to contact valve seat.
Further, blocking material plate is rubber plate, and when blocking material plate and projection contacts, micro-deformation also can occur two blocking material plates so that two blocking material plates and projection contacts more tight, further ensures plastic cement and can not contact valve seat.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model rubber injection mold check valve embodiment;
Fig. 2 is the schematic diagram of prior art in background technology.
Embodiment
Below by embodiment, the utility model is described in further detail:
