Abstract
The utility model belongs to casting field, disclose a kind of self-hardening sand casting flask-closing positioner, with solve the problems, such as in self-hardening sand foundry production in the prior art using self-hardening sand positioning pin cause positioning pin shear resistance it is poor, positioning it is inaccurate, the device includes the upper positioning body being arranged in sand mold and the lower positioning body being arranged in lower sand mold, upper positioning body is equipped with upper groove, lower positioning body is equipped with lower groove, upper groove is opposite with the opening of lower groove, and upper groove in the cavity of lower groove formation with being provided with positioning pin.So that die joint upper and lower sand mold accurate positioning during mould assembling, and positioner is reusable, is effectively saved cost, the utility model is simple in structure, and positioning is reliable, thoroughly avoids the problem of traditional sand mold positioning pin is easy to wear, positioning is inaccurate.
Description
Technical field
It the utility model is related to casting field, and in particular to a kind of self-hardening sand casts flask-closing positioner.
Background technology
In traditional self-hardening sand foundry production, usually using cope, drag box moulding, the special casting in part
Also need to set intermediate box.Positioner used in it is generally the sand mold positioning pin made of self-hardening sand.Though sand mold positioning pin
Certain positioning action can be so played, and there is certain tension and compression strength, but its shear resistance is poor, and using
During it is easy to wear, cause that positioning is inaccurate, and the prior art can not solve above-mentioned technical problem.
Utility model content
The purpose of this utility model is to solve to use self-hardening sand in self-hardening sand foundry production in the prior art
Positioning pin causes the problem of positioning pin shear resistance is poor, positioning is inaccurate, there is provided a kind of self-hardening sand casting mould assembling positioning dress
Put.
In order to achieve the above object, the utility model uses following technical scheme：A kind of self-hardening sand casting mould assembling positioning dress
Put, including the upper positioning body being arranged in sand mold and the lower positioning body being arranged in lower sand mold, upper positioning body are equipped with upper
Groove, lower positioning body is equipped with lower groove, and upper groove is opposite with the opening of lower groove, the cavity that upper groove is formed with lower groove
In positioning pin is installed.
Further improved as the utility model, positioning pin is symmetrical cylinder overall structure broad in the middle, two is small.
Further improved as the utility model, upper groove and lower groove are round recessed.
Further improved as the utility model, the upper surface of the lower face of upper positioning body and lower positioning body is respectively positioned on point
On type face.
The utility model has the advantages that relative to the prior art:A kind of self-hardening sand casting of the utility model
The positioner of mould assembling in molding, repairing type, brushed mould assembling before, first positioning pin is put into lower groove, then mould assembling, by fovea superior
Groove is sleeved on positioning pin, then carries out subsequent job so that die joint upper and lower sand mold accurate positioning during mould assembling, and positioner can
Reuse, be effectively saved cost, the utility model is simple in structure, and positioning is reliable, thoroughly avoids traditional sand mold positioning
Sell the problem of easy to wear, positioning is inaccurate.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Reference numeral implication is as follows：1. upper positioning body；2. positioning pin；3. lower positioning body；Sand mold on 4.；5. lower sand
Type；6. upper groove；7. lower groove.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, a kind of self-hardening sand casting flask-closing positioner, including the upper positioning body 1 being arranged in sand mold 4 with
And the lower positioning body 3 in lower sand mold 5 is arranged on, the upper surface of the lower face of upper positioning body 1 and lower positioning body 3 is respectively positioned on parting
On face.Upper positioning body 1 is equipped with upper groove 6, and lower positioning body 3 is equipped with lower groove 7, the opening phase of upper groove 6 and lower groove 7
It is right, and upper groove 6 in the cavity of the formation of lower groove 7 with being provided with positioning pin 2.Positioning pin 2 is the small symmetrical circle in broad in the middle, two
Column overall structure, upper groove 6 and lower groove 7 are round recessed.
In design template formative technology moulding, upper positioning body 1, lower positioning body 3 are individually placed to the opposite of upper and lower template
On position, then carry out moulding operation.Molding, repairing type, when having brushed mould assembling, positioning pin 2 is applied after spreading butter, is first placed in recessed
In groove 7, mould assembling is then carried out again so that upper groove 6 is packed among positioning pin 2.
In non-template formative technology modeling process, before lower 5 moulding of sand mold, first lower groove 7 is placed on beside model
Appropriate position, then carry out moulding.After mould turnover, on carrying out before the moulding of sand mold 4, positioning pin 2 is placed in lower groove 7, will
Upper groove 6 is sleeved on positioning pin 2 and then carries out moulding.Molding, repairing type, when having brushed mould assembling, positioning pin 2 is applied and spreads Huang
After oil, first it is placed in lower groove 7, then carries out mould assembling again so that upper groove 6 is packed into positioning pin 2.
