Abstract
The utility model relates to the technical field of casting, and specifically discloses an inner locating pin device capable of locating accurately. The inner locating pin device capable of locating accurately comprises an upper case and a lower case; and the inner locating pin is characterized in that the locating grooves of the upper case and the lower case are respectively embedded with locating bushes, and a locating pin is arranged between the locating bushes of the upper case and lower case. In comparison with the prior art, the added locating bushes are sleeved on the locating pin of the mold in advance, after modeling, the locating bushes are left in the casting mold to form a locating hole, the locating bushes are added in the upper and lower cases, the locating bushes are embedded in a sand mold, a guide contact face in the case closing process is changed skillfully, the original contact between the sand molds is changed into the contact between metals, strength is increased, and dislocation is avoided.
Description
Technical field
The utility model relates to casting technology field, specifically the pinpoint interior dowel device of a kind of energy.
Background technology
In the sand casting, mould assembling is must operation.Want accurate positioning when requiring upper and lower case to engage, the horizontal plane four direction can not have deviation.Otherwise will cause the foundry goods misalignment, size is not inconsistent, and increases the polishing workload or scraps.
Accurate positioning when keeping nowel to engage, commonly used have two kinds of positioners.
Outside fix in the sandbox outside, is loaded onto guider, is commonly called as the backer.Its advantage is that the location is correct, but its shortcoming is easily to walk about, and its integrality of frequent maintenance test; Sandbox will pass through machining, and the range of work is sandbox side and composition plane, and processing capacity is large, to large-scale sandbox, make plane machining with heavy duty machine tools, and cost is high.
Interior location, placement is no less than 3 mould assembling alignment pin on the composition surface.Advantage is that cost is low, does not increase the moulding workload.But it is inaccurate that it has obvious deficiency to locate exactly.
Summary of the invention
The utility model is for overcoming the deficiencies in the prior art, newly-increased positioning sleeve is enclosed within on the alignment pin that is installed on the model in advance, moulding is complete, and positioning sleeve is stayed in the casting mold, forms locating hole, in upper and lower case, increased positioning sleeve, positioning sleeve is embedded in sand mold, has changed dexterously the guiding contact-making surface in the mould assembling process, is contacted with sand mold by original sand mold and changes metal and Metal Contact into, gain in strength, avoid dislocation.
For achieving the above object, design the pinpoint interior dowel device of a kind of energy, comprise top box, nowel, it is characterized in that: in the locating slot of top box and nowel, be embedded with respectively positioning sleeve, be provided with alignment pin between the positioning sleeve of top box and nowel.
Described positioning sleeve is the sleeve of up-narrow and down-wide circle, the bottom outer rim connection bump seat of sleeve.
The outer surface of described sleeve and the angle between the boss are 95 °.
The utility model is compared with prior art, newly-increased positioning sleeve is enclosed within on the alignment pin that is installed on the model in advance, moulding is complete, and positioning sleeve is stayed in the casting mold, forms locating hole, in upper and lower case, increased positioning sleeve, positioning sleeve is embedded in sand mold, has changed dexterously the guiding contact-making surface in the mould assembling process, is contacted with sand mold by original sand mold and changes metal and Metal Contact into, gain in strength, avoid dislocation.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the positioning sleeve enlarged diagram.
Referring to Fig. 1,1 is top box, and 2 is positioning sleeve, and 3 is alignment pin, and 4 is nowel.
Referring to Fig. 2,2-1 is sleeve, and 2-2 is boss.
The specific embodiment
The below is described further the utility model with reference to the accompanying drawings.
Such as Fig. 1, shown in Figure 2, in the locating slot of top box 1 and nowel 4, be embedded with respectively positioning sleeve 2, be provided with alignment pin 3 between the positioning sleeve 2 of top box 1 and nowel 4.
Positioning sleeve 2 is the sleeve 2-1 of up-narrow and down-wide circle, the bottom outer rim connection bump seat 2-2 of sleeve 2-1.
Angle between the outer surface of sleeve 2-1 and the boss 2-2 is 95 °.
Alignment pin 3, positioning sleeve 2 all adopt the cast iron manufacturing.
When upper and lower case moulding, newly-increased positioning sleeve 2 is enclosed within on the alignment pin 3 that is installed on the model in advance respectively, moulding is complete, and positioning sleeve 2 is stayed in the casting mold, forms locating hole.
During mould assembling, alignment pin 3 is put into nowel positioning sleeve 2, again the positioning sleeve 2 of top box is aimed at alignment pin 3, and at this moment, the contact-making surface between positioning sleeve 2 and the alignment pin 3 is metal, and intensity is enough, can play the guiding role, therefore can accurately locate.
After unpacking, positioning sleeve 2, alignment pin 3 can be reclaimed Reusability.Alignment pin 3, positioning sleeve 2 can be according to the sandbox size scalings.
Positioning sleeve 2 can replace with centring ring, can save material, and principle is identical.
Claims (3)
1. pinpoint interior dowel device of energy, comprise top box, nowel, it is characterized in that: in the locating slot of top box (1) and nowel (4), be embedded with respectively positioning sleeve (2), be provided with alignment pin (3) between the positioning sleeve (2) of top box (1) and nowel (4).
2. the pinpoint interior dowel device of a kind of energy according to claim 1 is characterized in that: described positioning sleeve (2) is the sleeve (2-1) of up-narrow and down-wide circle, the bottom outer rim connection bump seat (2-2) of sleeve (2-1).
3. the pinpoint interior dowel device of a kind of energy according to claim 2, it is characterized in that: the angle between the outer surface of described sleeve (2-1) and the boss (2-2) is 95 °.
