Description
Technical field
The present invention relates to shaping investment pattern fields, particularly, are related to a kind of forming die for wax pattern.
Background technique
The design of forming die for wax pattern and manufacture have significant impact for precision castings, and directly affect wax-pattern after molding
Surface smoothness and dimensional accuracy, therefore forming die for wax pattern need to meet several requirements: 1) guarantee that the wax-pattern molded can reach
The dimensional accuracy and surface roughness of design requirement；2) it is convenient to mount and dismount, is light and handy, is durable, molding convenience；3) each part of die mould
It answers easy to process.
Now need the structure of certain molding guider inner ring wax-pattern as shown in attached drawing Fig. 1, which has 12 101 Hes of gusset
Boss 103 at 12, and there are deep trouths 102 between adjacent webs 101.Existing mold stripping method is divided into two kinds: first is that according to wax-pattern shape
Cover board is made into punch-pin by shape, and this comparison is suitble to the simple part of structure, if surface is the part of plane, in order to avoid feeling suffocated,
Venting plug can be set in the plane；Second is that split into multiple loose pieces according to wax-pattern shape, then by loose piece when operator's depanning
Take out upwards one by one, this method is relatively suitble to the less part of loose piece, such as split 2~4 pieces can depanning part.
And for multiple gussets 101, boss 103,102 inner cavity of deep trouth wax-pattern for, mold stripping method routinely,
Due to mold inner-cavity complexity, the devices such as exhaust valve can not be installed in 102 slot of deep trouth, when suppressing wax-pattern, wax-pattern gusset 101 and deep trouth
Biggish package power is formed with die cavity at 102, wax-pattern is will cause and feels suffocated, wax-pattern is readily adsorbed on mold when depanning, once wax
Mould is adsorbed on mold, due to the obstruction at wax-pattern contraction and multiple gussets 101, boss 103, be will lead to wax-pattern and is difficult to take out,
Such as modulus by force, it will cause wax-pattern deformation and even destroy；In addition, this structure is such as taken out using the multiple loose pieces of fractionation, if
Also need to consider the positioning between loose piece when counting loose piece, operating procedure is various when loose piece takes out, and one is also needed after modulus
A match loose piece restores, operator's large labor intensity, low efficiency.
Summary of the invention
The present invention provides a kind of forming die for wax pattern, existing wax-pattern when solving existing forming die for wax pattern depanning
It is difficult to take out, the technical issues of operating procedure is more when loose piece takes out, operator's large labor intensity, depanning low efficiency.
