Welding tooling and the method for part die cavity filled by a kind of low-melting-point metal, and cavity filling frock overall dimensions is the 0.7 0.9 of the interior cavity dimension of part, ensures that it can be with easy access in part outlet simultaneously, and cavity filling frock is formed by plate welding, hollow；Low-melting-point metal is in order to fill the space between the interior die cavity of part and cavity filling frock, and the consumption of low-melting-point metal gets with the calculating of cavity filling frock volume differences according to die cavity in part；Forward and backward closure plate big 10 20mms more monolateral than the two ends outlet size of part, are welded in the two ends outlet of part.Different parts only need to be changed the welding that cavity filling frock just can easily realize the profile flow passage cover plate of variously-shaped, the thin part of sandwich runner, thickness by the present invention, improves production efficiency；Filling frock reusability, in the filling of low-melting-point metal can guarantee that part, profile is propped up completely, prevents from welding the deformation caused simultaneously.Especially thin-walled, the sandwich class part of irregular shape there is the good suitability.
Description
Technical field
The present invention relates to welding procedure, particularly suitable profile sandwich runner, the die cavity class zero that body length, simultaneously wall thickness are the thinnest
The welding of part, welding tooling and the method for part die cavity filled by a kind of low-melting-point metal.
Background technology
See Fig. 1, the thinnest die cavity class part of sandwich runner, body length, simultaneously wall when welding profile flow passage cover plate easily
Cause deformation, especially in welding, die cavity time-varying shape is serious, even directly results in part rejection.So at welding profile runner lid
During plate, the interior die cavity of part must design and be propped up by interior die cavity with welding tooling.Design in the case of considering dress, tearing open easily
In the external surface of welding tooling props up part, profile is typically all interruption, as shown in Figures 2 and 3.And for as middle type
The die cavity class part that chamber is big, two ends outlet is little is inapplicable, and in the welding tooling being interrupted can not be completely secured part, die cavity is constant
Shape, the position not having frock to prop up still deforms substantially, it may be said that such welding tooling is unsatisfactory.
Summary of the invention
Die cavity class part in order to solve sandwich runner, body length, simultaneously wall are the thinnest exists at welding profile flow passage cover plate
The problem being easily deformed, the present invention proposes a kind of low-melting-point metal and fills welding method and the frock of part die cavity.
The welding tooling of part die cavity filled by this low-melting-point metal, including cavity filling frock, low-melting-point metal, front
Closure plate and rear blocking plate, it is characterised in that cavity filling frock overall dimensions is the 0.7-0.9 of the interior cavity dimension of part, simultaneously
Ensureing that it can be with easy access in part outlet, cavity filling frock is formed by plate welding, hollow；Low-melting-point metal is in order to fill
Space between interior die cavity and the cavity filling frock of part, the consumption of low-melting-point metal is according to die cavity in part and cavity filling
Frock volume differences calculates and gets；Forward and backward closure plate big 10-20mm more monolateral than the two ends outlet size of part, is welded on the two of part
Bring out on mouth.
The welding method of part die cavity filled by this low-melting-point metal, it is characterised in that step is as follows:
One, front closure plate is blocked the outlet of part small end, front closure plate spot welding is fixed on part exit end face；
One end that two, part is welded with front closure plate is placed in down on platform and fixes, and cavity filling frock is loaded in part
In die cavity；
Three, low-melting-point metal is heated, ensure homogeneous heating as far as possible, treat that low-melting-point metal is completely melt into liquid, i.e. with filling out
Dress spoon scoop liquid low-melting-point metal load in part die cavity with in the gap of cavity filling frock, until all gaps are filled up；
Four, cover rear blocking plate and fix with spot welding；
Five, after part entirety cools down, the profile runner of part can be carried out cover plate welding；
Six, after part flow passage cover plate has welded, closure plate and rear blocking plate before two ends is polished off, by whole for the part of band low-melting-point metal
Body is delivered in heat-treatment furnace, heats up and all melts out by low-melting-point metal, and collects low-melting-point metal to repeat with collecting vessel
Use.
Spot welding is argon arc welding.
Low-melting-point metal be lead, stannum, aluminum or they two or three alloy.
Present configuration is simple, different parts only need to be changed cavity filling frock just can easily realize variously-shaped,
The welding of the profile flow passage cover plate of the thin part of sandwich runner, thickness, it is possible to time-consuming, improves production efficiency；Fill simultaneously
Frock reusability, saves production cost.In the filling of low-melting-point metal can guarantee that part, profile is propped up completely, prevents
The deformation that welding causes.Especially thin-walled, the sandwich class part of irregular shape there is the good suitability.

Detailed description of the invention
Below by embodiment, and combining accompanying drawing, the invention will be further described.
In embodiment, low-melting-point metal is lead, 358 ° of C of the fusing point of lead.
This lead material fill part die cavity welding tooling, including cavity filling frock 4, lead material 3, front closure plate 5 and after
Closure plate 6, cavity filling frock 4 overall dimensions is the 0.8 of the interior cavity dimension of part, ensures that it can be in part outlet turnover simultaneously
Freely, cavity filling frock 4 is formed by plate welding, hollow；Lead material 3 is in order to fill interior die cavity and the cavity filling frock of part
Space between 4, the consumption of lead material 3 gets with the calculating of cavity filling frock 4 volume differences according to die cavity in part；Front closure plate 5, after
Closure plate 6 big 15mm more monolateral than the two ends outlet size of part, is welded in the two ends outlet of part with argon arc welding point.
The welding method of part die cavity filled by this lead material, and step is as follows:
One, front closure plate is blocked up 5 and lives the outlet of part 1 small end, the argon arc welding spot welding of front closure plate 5 is fixed on part 1 exit end face；
One end that two, part 1 is welded with front closure plate 5 is placed in down on platform and fixes, and cavity filling frock 4 is loaded part
1 inner mold intracavity；
Three, the lead 3 of solid is heated, ensure homogeneous heating as far as possible, treat that lead is completely melt into liquid, i.e. scoop liquid with filling spoon
Shape lead 3 load in part die cavity with in the gap of cavity filling frock 4, until all gaps are filled up；
Four, cover rear blocking plate 6 and fix with argon arc welding spot welding；
Five, after part entirety cools down, the profile runner of part can be carried out cover plate welding；
Six, after part flow passage cover plate 7 has welded, polish off closure plate 5 and rear blocking plate 6 before two ends, the part entirety of band lead is sent
To heat-treatment furnace, heat up and all melt out by lead, and collect lead metal to reuse with collecting vessel.
