Abstract

The utility model discloses a middle-layer sand mould with a double-surface inner positioning taper hole, which comprises a lower mould plate, a sand box, a mould core, and a lower positioning pin cone arranged on the lower mould plate. The characteristics are as follows: the top of the mould core is provided with a groove, and the bottom of the groove is provided with a threaded hole; a fixed positioning mould plate is arranged in the groove; the fixed positioning mould plate is further provided with a movable positioning mould plate; the fixed positioning mould plate is connected with a movable positioning mould plate through at least two positioning pins and a locking bolt; the lower part of the movable positioning mould plate is provided with at least two positioning pin cones. In the utility model, the double-surface inner positioning taper hole is processed through the mould; the middle-layer sand mould has advantages of high positioning precision and production efficiency, ensures casting quality, and meets requirements of batch production.

Description

Middle level sand mold mould with location taper hole in two-sided
Technical field
The utility model relates to the middle level sand mold mould in a kind of casting.
Background technology
In sand casting process, when the foundry goods shape is complicated, usually need use multilayer somatotype casting mould, as shown in Figure 1, be about to mould and be divided into three-part flask from top to bottom, be respectively equipped with sand mold in each layer sandbox, adopt this structure, the accurate location between every layer of sandbox is that decision casting quality quality is crucial; Traditional multilayer somatotype casting mould, be respectively arranged with the longitudinal register taper hole 14 of at least two pairings on the adjacent interfaces of last sand mold 11 and middle level sand mold 12, middle level sand mold 12 and following sand mold 13, in every pair of location taper hole 14, be provided with the alignment pin awl 15 of coupling, can realize accurate location; Wherein go up sand mold 11 and 13 need of following sand mold and the location taper hole is set, can be easy to realize by the mould manufacturing at single face; Middle level sand mold 12 must be provided with location taper hole 15 at upper and lower surface, the location taper hole of its lower surface also can be by the mould manufacturing, but the location taper hole 15 of its upper surface can't come out by Mould Machining, can only locate by the mode of manual line, its positioning accuracy is lower, reduced casting quality, and efficient is low, can't satisfies the needs of batch process.
Summary of the invention
The purpose of this utility model is that a kind of middle level sand mold mould with location taper hole in two-sided is provided at the above-mentioned deficiency of prior art, and it has positioning accuracy height and advantage of high production efficiency.
The purpose of this utility model is achieved in that
A kind of middle level sand mold mould with location taper hole in two-sided, comprise lower bolster, sandbox, core, be arranged at the following alignment pin awl on the counterdie, it is characterized in that: be provided with groove and be provided with screw at bottom portion of groove at the top of apperance, be provided with the stationary positioned template in the groove, on the stationary positioned template, also be provided with the activity orientation template, the stationary positioned template is connected with a clamping screw by at least two alignment pins with the activity orientation template, and alignment pin awl on two also is being housed below the activity orientation template at least;
During moulding, put into resin sand, the oblique Piles of back-up sand face palpus that the position by the activity orientation Shuttering blind is tight, and to guarantee the intact of sand mold, resin sand solidifies the tight bolt of back releasable lock, takes off alignment pin and activity orientation template, realizes the sand mold demoulding;
The utility model goes out two-sided interior location taper hole by Mould Machining, has positioning accuracy height and advantage of high production efficiency.
Description of drawings
Fig. 1 is the structural representation of existing multilayer somatotype casting mould.
Fig. 2 is a front view of the present utility model.
Fig. 3 is the vertical view of Fig. 2.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
By Fig. 2 and shown in Figure 3, this middle level sand mold mould, comprise lower bolster 1, sandbox 2, core 3, be arranged at the following alignment pin awl 4 on the counterdie 1, be provided with groove and be provided with screw at the top of core 3 at bottom portion of groove, be provided with stationary positioned template 5 in the groove, also be provided with activity orientation template 6 on stationary positioned template 5, stationary positioned template 5 is connected with a clamping screw 8 by two alignment pins 7 with activity orientation template 6, and alignment pin awl 9 on two also is being housed below the activity orientation template 5;
During moulding, put into resin sand 10, the oblique Piles of back-up sand face palpus that is being kept off the position by activity orientation template 6 is tight, and to guarantee the intact of sand mold, resin sand solidifies the tight bolt 8 of back releasable lock, takes off alignment pin 7 and activity orientation template 6, realizes the sand mold demoulding; The utility model goes out two-sided interior location taper hole by Mould Machining, has positioning accuracy height and advantage of high production efficiency, has guaranteed casting quality, can satisfy the needs of batch process.
