Description

A kind of structure of the anti-mispointing of Piston mould

Technical field

This utility model relates to the structure of the anti-mispointing of a kind of Piston mould, belongs to engine mould technical field.

Background technology

Electromotor be a kind of can the machine that can be converted into mechanical energy of other form, including as internal combustion engine, external-combustion engine, Motor etc., its application contains the every field that plant equipment is relevant substantially, wherein, important as electromotor of engine piston Assembly, the quality of its quality will directly affect the service life of electromotor.Engine piston in the fabrication process, in order to adapt to it Polymorphic structure, it is often necessary to many group moulds with the use of, due to requirements such as piston are regular, eccentric, exist at Piston mould Being reserved with corresponding mark on mould, therefore mould can not be anti-loaded when assembling, when piston blank otherwise can be caused to cast, makes to live Plug blank is affected by mark and the factor such as eccentric and is scrapped, and after these mould life-time service, identifies and gradually obscure, and causes point The problem distinguishing difficulty, directly influences mould and installs and uses.

Summary of the invention

For solving problems of the prior art, this utility model provides the knot of the anti-mispointing of a kind of Piston mould Structure, concrete technical scheme is as follows:

The structure of the anti-mispointing of a kind of Piston mould, including interior mould SMIS and Nei Mo big limit core；Described interior mould SMIS side There is tongue shape external part, described tongue shape external part offers the SMIS mozzle running through surface；Described interior mould big limit core has Arch connects end, and described interior mould big limit core offers limit core mozzle, described interior mould big limit core offers sensing arch even Connect the drainage trough of end；Described limit core mozzle is the most corresponding with SMIS mozzle and drainage trough is bonded to each other with tongue shape external part； The position being positioned at tongue shape external part side on described interior mould SMIS is provided with mistake proofing alignment pin, with mistake proofing on the core of described interior mould big limit The position that alignment pin is corresponding is provided with anti-mispointing hole.

As the improvement of technique scheme, described mistake proofing alignment pin is fixedly installed on position, tongue shape external part oblique upper, Mutually stagger with drainage trough in the vertical direction with mistake proofing alignment pin snap fit and anti-mispointing hole in described anti-mispointing hole.

As the improvement of technique scheme, described interior mould SMIS side opening is provided with external mold connecting hole, described interior mould SMIS By running through, the fastening bolt of external mold connecting hole is fixing with external mold to be connected；Tongue shape groove, described tongue shape groove is offered on described external mold The most corresponding with tongue shape external part.

As the improvement of technique scheme, described arch connection end offering limit core fixing hole, described limit core is fixed Hole is evenly distributed on arch and connects the arch edge side of end.

In technique scheme, interior mould SMIS has mistake proofing alignment pin, on this mistake proofing alignment pin and interior mould big limit core Anti-mispointing hole cooperates so that interior mould SMIS and Nei Mo big limit core anti-loaded after cannot proper engagement, stopped mould anti-loaded Possibility, thus after avoiding existing mould anti-loaded, cause the problem directly scrapped of piston blank of cast, beneficial effect is notable.

Detailed description of the invention

As shown in Figure 1, Figure 2, Figure 3, Figure 4, this utility model provides the structure of the anti-mispointing of a kind of Piston mould, including Interior mould SMIS 10 and Nei Mo big limit core 20；Described interior mould SMIS 10 side has tongue shape external part 11, described tongue shape external part 11 On offer the SMIS mozzle 12 running through surface；Described interior mould big limit core 20 has arch and connects end 21, the described big limit of interior mould Offer limit core mozzle 22 on core 20, described interior mould big limit core 20 offers the drainage trough 23 pointing to arch connection end 21； Described limit core mozzle 22 is the most corresponding with SMIS mozzle 12 and drainage trough 23 is bonded to each other with tongue shape external part 11；Described The position being positioned at tongue shape external part 11 side on interior mould SMIS 10 is provided with mistake proofing alignment pin 13, on described interior mould big limit core 20 with The position of mistake proofing alignment pin 13 correspondence is provided with anti-mispointing hole 24；During use high temperature alloy solution by limit core mozzle 22 with SMIS mozzle 12, is injected in drainage trough 23, forms the piston blank structure of corresponding construction after cooling.

In such scheme, interior mould SMIS 10 has mistake proofing alignment pin 13, this mistake proofing alignment pin 13 and interior mould big limit core 20 On anti-mispointing hole 24 cooperate so that after interior mould SMIS 10 and Nei Mo big limit core 20 is anti-loaded cannot proper engagement, stop The possibility that mould is anti-loaded, thus the problem causing the piston blank of cast directly to be scrapped after avoiding existing mould anti-loaded, have Benefit effect is notable.

Further, described mistake proofing alignment pin 13 is fixedly installed on position, tongue shape external part 11 oblique upper, and described mistake proofing is fixed Mutually staggering with drainage trough 23 in the vertical direction with mistake proofing alignment pin 13 snap fit and anti-mispointing hole 24 in hole 24, position, should Preferred version, by limiting mistake proofing alignment pin 13 and the position in anti-mispointing hole 24, reduces this mistake proofing location structure to drainage trough 23 Impact, it is ensured that being smoothed out of piston blank manufacturing process.

Further, described interior mould SMIS 10 side opening is provided with external mold connecting hole 14, and described interior mould SMIS 10 is by passing through Wear that the fastening bolt 40 of external mold connecting hole 14 is fixing with external mold 30 to be connected；Tongue shape groove 31, described tongue is offered on described external mold 30 Shape groove 31 is the most corresponding with tongue shape external part 11；This preferred version provides a kind of concrete interior mould SMIS 10 and fixes with external mold 30 The structure connected.

Further, described arch connection end 21 offering limit core fixing hole 25, described limit core fixing hole 25 is uniform Being distributed in arch and connect the arch edge side of end 21, this preferred version provides mould big limit core 20 and other set of molds in one The fixed structure that part connects, and by limiting the position of limit core fixing hole 25, improve the stability of this fixed structure.
