Abstract
The utility model relates to an ejector rod devoice for an investing mould, and in particular relates to a semi-automatic ejector rod devoice for an investing mould. The technical scheme is as follows: the device comprises a control valve, a pneumatic pipeline, a cylinder, push rods, a push rod fixing plate, a push element plate and a base plate; the base plate is provided with the push rod fixing plate; the push rod fixing plate is provided with a plurality of groups of push rods; the push element plate is arranged below the push rod fixing plate; the cylinder is arranged below the push element plate; the cylinder is externally connected with the pneumatic pipeline and the control valve; the cylinder is movably connected with the push rod fixing plate; the control valve is used for controlling ejection and restoration of the push rods. The device disclosed by the utility model has the beneficial effects that the acting force is uniformly distributed on the push rod fixing plate; the compressed air is used as a power source; the problem of uneven acting force caused by manual operation is reduced; the labor of an operator is reduced by adopting semi-automatic operation, and simultaneously deformation of wax mould is reduced and the surface quality of the wax mould is improved.
Description
Technical field
The utility model relates to a kind of investment casting mold pin-lift arrangement, particularly the semi-automatic pin-lift arrangement of a kind of investment casting mold.
Background technology
In the investment casting process, having many is products that appearance and size is large, simple in structure, production lot is large, delivery is inconvenient.Some moulds, even increased push rod, push piece plate, effect is also undesirable.Because push rod, push piece plate are by External Force Acting, wax-pattern is deviate from smoothly, the size of active force, contact area has directly affected the effect of delivery.Use push rod, push piece plate delivery to cause the distortion of wax spare, the push rod vestige is serious.Especially the product on some large planes of thin-walled, even the phenomenon that has wax spare to penetrate.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of investment casting mold semi-automatic pin-lift arrangement.
Its technical scheme is: comprise control valve, pneumatic line, cylinder, push rod, ejector pin retaining plate, push piece plate, base plate, base plate is provided with ejector pin retaining plate, ejector pin retaining plate is provided with many group push rods, be provided with the push piece plate below the ejector pin retaining plate, the below of push piece plate is provided with cylinder, the external pneumatic line of cylinder and control valve, cylinder and ejector pin retaining plate are flexibly connected, ejecting and reset by control valve control push rod.
The below of above-mentioned push piece plate is provided with many group support columns.
Above-mentioned cylinder adopts with ejector pin retaining plate and is threaded.
The both sides of above-mentioned base plate are provided with cushion block, and lower bolster is supported in the top of cushion block, and lower bolster is provided with cope match-plate pattern.
The beneficial effects of the utility model are: active force is evenly distributed on the ejector pin retaining plate, employing compressed air is power source, reduce the active force problem of non-uniform that manual operation brings, owing to having adopted semi-automatic operation, reduced operator's work, simultaneously, reduce the wax-pattern distortion, improved the wax-pattern surface quality.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model;
Among the upper figure: control valve 1, pneumatic line 2, support column 3, cylinder 4, handle 5, cope match-plate pattern 6, lower bolster 7, push rod 8, cushion block 9, ejector pin retaining plate 10, push piece plate 11, base plate 12.
The specific embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model comprises control valve 1, pneumatic line 2, support column 3, cylinder 4, handle 5, cope match-plate pattern 6, lower bolster 7, push rod 8, cushion block 9, ejector pin retaining plate 10, push piece plate 11, base plate 12, base plate 12 is provided with ejector pin retaining plate 10, ejector pin retaining plate 10 is provided with many group push rods 8, be provided with push piece plate 11 below the ejector pin retaining plate 10, the below of push piece plate 11 is provided with cylinder 4, cylinder 4 external pneumatic line 2 and control valves 1, cylinder 4 is flexibly connected with ejector pin retaining plate 10, ejecting and reset by control valve 1 control push rod 8.
Wherein, the below of push piece plate 11 is provided with many group support columns 3, and above-mentioned cylinder 4 adopts with ejector pin retaining plate 10 and is threaded, and the both sides of above-mentioned base plate 12 are provided with cushion block 9, and lower bolster 7 is supported in the top of cushion block 9, and lower bolster 7 is provided with cope match-plate pattern 6.
Characteristics of the present utility model are: (1) but be applicable to product in batches large, product size is large, simple in structure, use the product of push rod, push rod delivery; (2) can be used for the strict wall thickness of surface quality less than the product delivery of 3mm, reduce deformation of products
In the Mold Making stage, at first product is selected, for the product that appearance and size is large, simple in structure, production lot is large, delivery is inconvenient, after placing push rod or push piece plate, placement cylinder below the push piece plate, and connect control valve and pipeline, after the mould acceptance(check), carry out the compacting of wax-pattern, after the wax-pattern compacting, at first connect primer liner, then open cope match-plate pattern, use control valve control cylinder jack-up, wax spare is taken out smoothly, then put down cylinder, the push rod rear matched moulds that resets can be suppressed again.
