In the time using, described push rod 92 moves upward, and drives described the second upper plate 70, the second lower roof plate 80 to move upward, and then the cutting knife on described thimble 91 tops cuts runner 93 and product 94.
But said structure has because have four top boards, complex structure, die cost is high; The number of top board is more, increases mold height, and then increases forming machine tonnage.
In view of this, be necessary to develop a kind of mould undercut construction in fact, to address the above problem.
[summary of the invention]
Therefore, the purpose of this utility model is to provide a kind of mould undercut construction, solves that prior art mould undercut construction top board is many, complex structure, mold height is higher, tonnage is large problem.
In order to achieve the above object, the mould undercut construction that the utility model provides, is located at a plastic mould, and described mould has upper mounted plate, caster, mother module core, male die core, male model plate, the bottom plate sequentially set up, and this structure comprises:
Upper plate, is located between described male model plate and described bottom plate;
Lower roof plate, is located between described male model plate and described bottom plate, and is positioned at described upper plate below;
Push rod, through described bottom plate and be held in the below of described lower roof plate;
Limited post, under matched moulds state, its one end is held in described caster, and the other end is held in described bottom plate, when described push rod does not eject, between described limited post and described lower roof plate, has the first distance, and described limited post below is provided with spacing thimble;
The first thimble, its one end is fixed between described upper plate and described lower roof plate, and the other end has cutting knife, and when described push rod does not eject, described cutting knife is near between product and runner.
Optionally, described mould undercut construction is also provided with the second thimble, and under matched moulds state, its one end is held in described bottom plate, when described push rod does not eject, between described the second thimble and described lower roof plate, has second distance.
Optionally, described the second thimble has several.
Optionally, the angle of described cutting knife and horizontal direction is 40～50 degree.
Optionally, the angle of described cutting knife and horizontal direction is 45 degree.
Optionally, the value of described the first distance equals described runner glue position one-tenth-value thickness 1/10 and deducts the value of a safe clearance.
Optionally, the value of described second distance equals described runner glue position one-tenth-value thickness 1/10 and deducts the value of a safe clearance.
Compared to prior art, utilize mould undercut construction of the present utility model, in the time ejecting, described push rod promotes described upper plate and lower roof plate, described the first thimble upwards ejects, and the cutting knife at described the first thimble top cuts described product and described runner, because now temperature is higher, be easy to cutting, thereby complete petty inscribe action.When described lower roof plate has moved after the first distance, described lower roof plate contacts with the spacing thimble of described limited post below, and described limited post upper and lower side is held in respectively caster and bottom plate.Therefore, the limited no longer motion of described the first thimble, avoids and mother module core collsion damage.Visible, utilize mould undercut construction of the present utility model, be reduced to two by four top boards before, top board is still less, simple in structure, mold height diminishes, tonnage is less.
