Abstract
The utility model relates to an automatic molding machine sand ejecting and compacting mechanism, which comprises a sand storing tank, a sand ejecting head, a pre-packing frame, a sand box, a convex mould and a workbench. Casting sand is arranged inside the sand storing tank the bottom of which is fixedly provided with the sand ejecting head; the bottom of the sand ejecting head is provided with a sand ejecting board; the center of the upper surface of the sand ejecting board is provided with a conical guide plate; the sand ejecting board at the circumference of the conical guide plate is evenly provided with sand ejecting holes with the same diameter; the pre-packing frame, the sand box and the workbench are coaxially arranged under the ejecting head; and the convex mould is arranged on the workbench coaxially. The main technical characteristic is that the section of the sand ejecting holes is a long circle and inclines outwards; and the circumferential side walls of the sand ejecting head are provided with assistant sand ejecting holes which are communicated with the sand box and are vertically downward. The utility model has the advantages of reasonable design, simple structure and high mould quality, which reduces the rejection rate and improves the production efficiency.
Description
Technical field
The utility model belongs to casting field, especially a kind of automatic moulding machine penetrate the sand system for compacting.
Background technology
Automatic moulding machine is the equipment that often uses on foundry production line.For big dark recessed moulding machine than foundry goods, because the effect of convex-concave cast model mold, the bottom of sandbox sand mold is recessed, so need add some molding sand to the sandbox periphery during back-up sand, adds some molding sand less to the sandbox middle part.This situation can be grasped control by operating personnel when artificial back-up sand, and just is difficult to control when machinery adds sand automatically.Because being machinery on the automatic moulding machine of foundry production line adds sand, and at sandbox middle part and the molding sand of periphery all be equally distributed (or equivalent distributes), therefore in the extrusion process of back, cause the degree of packing of molding sand inhomogeneous easily, thereby influenced the gas permeability of sand mo(u)ld and the surface quality of foundry goods.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of reasonable in design is provided, can effectively improve the uniform automatic moulding machine of foundry goods sand compaction penetrate the sand system for compacting.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of automatic moulding machine penetrate the sand system for compacting, comprise sand tank, sand-shooting head, fill out frame in advance, sandbox, the convex mold, workbench constitutes, be built-in with molding sand at sand tank, install a sand-shooting head in the bottom of sand tank, install one in the bottom of sand-shooting head and penetrate the sand plate, in the centre of penetrating sand plate upper surface one cone deflector is installed, penetrating on the sand plate around this cone deflector with the uniform sand-spraying hole that is shaped in footpath, fill out frame in advance, sandbox, the coaxial below that is installed in sand-shooting head of workbench, the convex mold is coaxial to be installed on the workbench, the cross section of described sand-spraying hole is an oblong shape and outward-dipping, is shaped on sandbox to be communicated with and auxiliary sand-spraying hole vertically downward on sidewall around the sand-shooting head.
And the outward-dipping angle of described sand-spraying hole is 10～30 degree.
And the quantity of described sand-spraying hole is eight.
And the quantity of described auxiliary sand-spraying hole is four.
Advantage of the present utility model and good effect are:
1. originally penetrating the sand system for compacting improves the structure of sand-shooting head, the uniform sand-spraying hole that is shaped on the sand plate of penetrating in the installation of sand-shooting head bottom, and each sand-spraying hole is all outward-dipping, when the progressive type sand blasting is penetrated, the molding sand of sand reservoir box can spray around sandbox, the back-up sand amount around the sandbox that makes increases relatively, and the back-up sand amount at sandbox middle part reduces, so just make the molding sand around the convex mold distribute more even, after the pressurization, make the convex mold upper end and the degree of packing all around relatively evenly rationally, thereby guaranteed to press the quality of sand.
2. originally penetrate the sand system for compacting and be shaped on the sidewall with sandbox around the sand-shooting head and be communicated with and auxiliary sand-spraying hole vertically downward, further around sandbox, spray molding sand, guaranteed sandbox back-up sand amount all around by auxiliary sand-spraying hole.
3. reasonable in design, simple in structure, the mold quality height of the utility model has reduced percent defective, has improved production efficiency.
Description of drawings
Fig. 1 is the utility model structural representation (broken section);
Fig. 2 is a structural representation of penetrating the sand plate.
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is further described.
A kind of automatic moulding machine penetrate the sand system for compacting, comprise sand tank 1, sand-shooting head 2, fill out frame 9, sandbox 5, convex mold 6 and workbench 7 in advance and constitute, be built-in with molding sand 12 at sand tank, bottom at sand tank installs sand-shooting head, penetrate sand plate 4 in the installation of the bottom of sand-shooting head, in this centre of penetrating sand plate upper surface one cone deflector 11 is installed, is utilized this cone deflector can be with the molding sand in the sand tank to the sand-spraying hole water conservancy diversion; This cone deflector penetrating on the sand plate with the footpath is uniform around this deflector is shaped on eight sand-spraying holes 10, the cross section of this sand-spraying hole is an oblong shape and outward-dipping, its angle of inclination is 10～30 degree, and the effect lower edge sand-spraying hole of the molding sand forced draft in the top in the sand tank sprays around sandbox.Around sand-shooting head, be shaped on the sidewall with the sandbox of its lower end and be communicated with and four auxiliary sand-spraying holes 3 vertically downward, the part in the molding sand in the sand tank under the effect of forced draft in die cavity around injection.Fill out the coaxial below that is installed in sand-shooting head of frame, sandbox, convex mold and workbench in advance, the convex mold is coaxial to be installed on the workbench, constitutes a spill die cavity 8 jointly by filling out frame, sandbox convex mold and workbench in advance.
Operation principle of the present utility model is:
Penetrate sand to sandbox under the effect of molding sand in the sand tank by forced draft, molding sand enters sandbox by penetrating eight made on sand plate sand-spraying holes, because male structure under below the sand-shooting head middle part being, occupy certain space, therefore sandbox middle part molding sand is less, and periphery is empty, therefore molding sand is just more, so just make convex mold middle part and molding sand on every side distribute relatively evenly, and then after by Driven by Hydraulic Cylinder the molding sand in the sandbox being pressurizeed, convex mold and sand compaction on every side thereof are more consistent, thereby have improved the quality of foundry goods.
Embodiment described in the utility model is illustrative; rather than it is determinate; therefore the utility model is not limited to the embodiment described in the specific embodiment; every by those skilled in the art according to other embodiments that the technical solution of the utility model draws, belong to the scope of the utility model protection equally.
