Abstract

The utility model relates to a casting pattern with an embedded part positioning module. The casting pattern comprises a die shoe and a module block. The module block is located on the die shoe. A moveable block is arranged at the matched part of a casting sand mould and the module block and is provided with the embedded positioning module in a matched manner. The embedded positioning module is in the shape of a circular truncated cone. The large diameter end of the embedded positioning module corresponds to the module block while the small diameter end of the embedded positioning module is axially provided with a threaded blind hole. A positioning and assembling blot is matched with the threaded blind hole. According to the utility model, an embedded part is not cast through a loam core, so that the cost of the loam core is lowered. The embedded part is positioned through a radial positioning face and an axial positioning face on the moveable block, so that the position and dimension precise of the embedded part is improved. As the loam core is omitted, the surface defects of wrong cores, fins and the like as well as the defects of cast pores caused by the loam core are eliminated or reduced.

Description

Casting pattern with insert locating module

Technical field

The utility model belongs to casting technology field, is specifically related to the casting pattern structural design.

Background technology

In some engineering machinery structural members, often need to embed the part of some nuts, cover, pin and so on, as Fig. 1.These cast structure spares embed part and generally are by modes such as loam cores down and be cast in the foundry goods in Foundry Production, not only increased the loam core cost, have also strengthened the risk that casting flaw appears in foundry goods.

Summary of the invention

Casting flaw for the foundry goods that reduces inserted num, cover, pin and so on part reduces production costs, and the utility model provides a kind of casting pattern with insert locating module.

Concrete technical solution is as follows:

Casting pattern with insert locating module comprises baffle plate 5 and model block 3, and model block 3 is positioned on the baffle plate 5, on the described model block 3, be provided with a movable block 4 with the casting sand type cooperation place, cooperates on the described movable block 4 to be provided with embedded locating module 6; Described embedded locating module 6 is the frustum of a cone, and its larger diameter end is corresponding with model block 3, and the end face of larger diameter end middle part has offered die cavity 12; Its smaller diameter end be axially arranged with tapped blind hole, cooperate with tapped blind hole to be provided with assembling bolt 8.

Embedded locating module 6 middle parts are provided with step and form the step-like frustum of a cone, and the taper seat of its smaller diameter end is radial location face 9, and the step surface adjacent with radial location face 9 is axial locating surface 10; In order to control the degree of depth that assembling bolt 8 enters tapped blind hole, offer perforation stop bit pin-and-hole 11 radially on the embedded locating module 6 corresponding with tapped blind hole the inner, be provided with fixing pin 7 in the stop bit pin-and-hole 11.

The utility model compared with prior art has the following advantages:

1. insert 2 of the present utility model does not need to have reduced the loam core cost by loam core embedding casting;

2. the location of the utility model insert 2 realizes that by the locating surface 9 on the model

loose piece

4,10 more accurate than loam core location dimension, the position dimension precision of insert is guaranteed;

3. owing to saved the loam core, the bleb defective of eliminating or having reduced blemish such as core shift, fash and caused because of the loam core;

4. the utility model is reasonable in design, and is simple in structure, can directly use the transformation of existing model.

The specific embodiment

Below in conjunction with accompanying drawing, do to describe further by the utility model of embodiment.

Referring to Fig. 1 and Fig. 2, the casting pattern with insert locating module comprises baffle plate 5 and model block 3, and model block 3 is positioned on the baffle plate 5.In order in foundry goods 1, to bury casting insert (nut) 2, on model block 3, be installed with a movable block 4 with the casting sand type cooperation place, cooperate on the movable block 4 embedded locating module 6 is installed, referring to Fig. 3.Embedded locating module 6 is the frustum of a cone, and the middle part is provided with step, and the taper seat of its smaller diameter end is radial location face 9, and the step surface adjacent with radial location face 9 is axial locating surface 10; Smaller diameter end be axially arranged with tapped blind hole, cooperate with tapped blind hole assembling bolt is installed; In order to control the degree of depth that assembling bolt 8 enters tapped blind hole, offer perforation stop bit pin-and-hole 11 radially on the embedded locating module 6 corresponding with tapped blind hole the inner, be provided with fixing pin 7 in the stop bit pin-and-hole 11.The end face middle part of its larger diameter end has offered die cavity 12.

Referring to Fig. 4, put sandbox 13 at casting pattern, add sand molding.After the moulding, trip out model block 3, but movable block 4 is still stayed in the casting mold 14, see Fig. 5, trip out embedded locating module 6 by the die cavity 12 that rises on the embedded locating module 6, the movable block 4 that recurs out is assembled to insert 2 then and embeds in the assembling bolt 8 of location, coats the joint sealing mudding in the termination of assembling bolt 8 (in the foundry goods die cavity) and closes.See Fig. 6.Last mould assembling, cast can be made the foundry goods 1 that has insert 2, after foundry goods 1 clears, but take off assembling bolt 8(reuse), see Fig. 7.
