Abstract

The invention discloses a sand core casting machine, which comprises a base, a sand core box arranged on the base, and an upright post arranged on the base and positioned at the tail end of the sand core box. A cover plate, a heat shield and an electric heating plate are arranged on the outer sidewall of the sand core box. Binding posts are arranged on the electric heating plate, and are extended out of the cover plate. The sand core box is further divided into a left sand core box and a right sand core box. Lower cantilevers and upper cantilevers are arranged at the tail ends of the left and right sand core boxes respectively, and are provided with holes matched with the upright post respectively. The upper part of the upright post is sleeved into the holes of the upper and lower cantilevers to open and close the left and right sand core boxes about the upright post in a rotating way. Cylindrical bushings are arranged between the left and right sand core boxes, and are matched with the upright post. Handles are arranged at the front ends of the left and right sand core boxes. A locking plate is arranged on one of the handles. The sand core casting machine provided by the invention is mainly used for manufacturing resin sand cores in batches with high efficiency, and the quality of the resin sand cores is stable.

Description

A kind of loam core casting machine

Technical field

The present invention relates to a kind of loam core Casting Equipment,

Background technology

During traditional casting and pouring foundry goods, generally pour into solidly for the through hole on the bulk article or blind hole (greater than 18mm, and less than 50mm), not only wasted a large amount of raw material, but also reduced machining efficient.

Summary of the invention

The technical problem to be solved in the present invention is in order to overcome technological deficiency recited above, a kind of loam core casting machine to be provided.

In order to solve technical problem recited above, the present invention takes following technical scheme:

The invention provides a kind of loam core casting machine, include base, be arranged on the core box on the base, be installed on the base and be positioned at the column of core box tail end; The lateral wall of core box is provided with cover plate, thermal insulation board and electric hot plate, and electric hot plate is provided with binding post, and binding post stretches out cover plate; Core box is further divided into left core box and right core box, the tail end of left side core box and right core box is respectively arranged with lower cantalever and upper cantilever, described upper cantilever is processed with the hole of matching with column respectively with lower cantalever, the top of described column packs in the hole of upper cantilever and lower cantalever, makes left core box, right core box rotate folding around column; Be provided with columniform lining between left side core box and the right core box, described lining matches with column; The front end of left side core box and right core box respectively is provided with handle, and one handle is provided with latch therein.

Described latch one end offers the notch that matches with another handle, and the other end is provided with miniature lever.

Be provided with at least two secondary linings between described left core box and the right core box, every width of cloth lining can be provided with how secondary lining according to the needs of producing for to cut into the Hough cover along cylindrical fore-and-aft cenlerline, overlaps even more as 2～6.

Hough " half ", foreign word transliteration Chinese name refers to the assembly (male model and master mold) after whole circular pieces cuts away half, and mainly refers to the subdivision structure on the engineering.Form is more, and the Hough cover is arranged, the Hough bearing, and haff nut, Hough flange etc., this noun of Hough hears seldom at machine industry that now what replaced is half-axile sleeve, half-and-half bearing, clasp nut etc.

The structure of described lining is the cylindrical structural of hollow, and the interior chamfering α of lining is the right angle.

Loam core of the present invention casting machine is mainly used in batch making resin loam core, efficient height, and resin loam core steady quality.

The present invention has been by having changed casting technique, the hole on the foundry goods put be designed to after the machine-finish allowance hollowly, pours into a mould at present that the loam core forms, and the foundry goods in following loam core has not only been saved a large amount of raw material, but also has improved machining efficient and casting hardness.

Among the figure, 1. cover plate, 2. thermal insulation board, 3. electric hot plate, 4. binding post, 5. left core box, 6. right core box, 7. lining, 8. base, 9. column, 10. positioning core axle, 11. packing rings, 12. handles, 13. fabroil cushion blocks, 14. miniature levers, 15. latch, 16. upper cantilevers, 17. lower cantalevers.

The specific embodiment

See also Fig. 1 to Fig. 3, as shown in the figure, the loam core casting machine includes base 8, and base 8 lower ends are provided with fabroil cushion block 13, are arranged on the core box on the base 8, is installed on the base 8 and is positioned at the column 9 of core box tail end; The lateral wall of core box is provided with cover plate 1, thermal insulation board 2 and electric hot plate 3, and electric hot plate 3 is provided with binding post 4, and binding post 4 stretches out cover plate; Core box is divided into left core box 5 and right core box 6, is provided with fourth officer lining 7 between left core box 5 and the right core box 6, and lining 7 matches with column 9; The tail end of left side core box 5 is provided with lower cantalever 17, the tail end of right core box 6 is provided with the upper cantilever 16 that cooperatively interacts with lower cantalever 17, upper cantilever 16 is processed with the hole of matching with column 9 respectively with lower cantalever 17, the top of column 9 packs in the hole of lower cantalever 17 and upper cantilever 16, makes left core box 5, right core box 6 around column 9 rotation foldings; Left side core box 5 respectively is provided with one handle 12 with the front end of right core box 6, handle 12 is provided with packing ring 11 with the installation place of core box, wherein one handle is provided with latch 15, and latch 15 1 ends offer the notch that matches with another handle, and the other end is provided with miniature lever 14.

See also Fig. 4 and Fig. 5, as shown in the figure, the structure of lining is the cylindrical structural of a hollow, chamfering α is the right angle in it, lining can carry out line and cut into two halves along the center line of its A-A view, form the Hough cover, is placed in the relevant position of left and right core box respectively.

The operation principle of loam core of the present invention casting machine is as follows: after each parts of loam core casting machine are assembled, and close left core box and right core box, the rotational lock plate makes the locking of left core box and right core box; Then resin sand is injected in the lining, fill up lining after, with electric hot plate energising heating, make the resin sand drying forming; The latch of outwarding winding is opened left and right core box, takes out the loam core.

Loam core of the present invention casting machine is mainly used in batch making resin loam core, and efficient height, and resin loam core steady quality can be made multi-cavity according to the loam core size.
