Abstract
The utility model discloses a casting die for machining a thin plate with a convex hull piece, comprising a male die and a female die. The casting die is characterized in that a casting insert which is bulged out of the reference surface of a male template is arranged under the male die, the lower bottom surface of the casting insert is provided with a forming surface cavity arranged at the upper surface of a convex hull part of a formed product, after the die is assembled, the casting insert is probed into the female die, and an integrated cavity for a convex hull part of a cast product is formed by the forming surface cavity arranged at the bottom of the casting insert and the cavity of the female die. According to the casting die, aiming at the local convex part of the product, the forming surface is arranged on the casting insert to be formed in cooperation with a main cavity, so that a die casting system is more flexible to design, and easy to change and replace.
Description
Technical field
The utility model belongs to mould applications, is specially a kind of processing with the thin plate casting mold of convex closure spare.
Background technology
Die cavity is the casting space that consists of the product profile in the mould, and the existing mold die cavity mostly is to consist of behind male model and the master mold matched moulds, for the local special shape of product, also more often adopts the moulding of the annex cooperation product sides such as taper pin in the mould.But for baroque convex closure spare on the similar light sheet products surface, simply accurately pouring procedure is arranged not yet.
Summary of the invention
Technical purpose of the present utility model is the purpose that solves prior art, and the thin plate of accurately casting mold processing of a kind of convenience with convex closure spare is provided.
The technical solution of the utility model is:
A kind of thin plate casting mold with convex closure spare, comprise male model and master mold, it is characterized in that, described male model below is provided with the mold insert of a protrusion male model plate datum level, described mold insert bottom surface is provided with the forming surface die cavity of shaped article convex closure position upper surface, behind the matched moulds, described mold insert probes in the master mold, the die cavity at the cast product convex closure position of the forming surface die cavity of mold insert bottom and the die cavity complete of master mold.In male model, design the upper surface that mold insert independently cooperates primary cavity moulding convex closure spare for convex closure spare, be easy to the demoulding, and side's change changes mold insert, can revise the forming shape at product convex closure position by changing mold insert, make processing more accurate.
The forming surface die cavity of described mold insert is to being recessed on, be provided with a taper pin in the described master mold, behind the matched moulds, the head of described taper pin stretches into the recess of mold insert forming surface die cavity, and the gap between the outer surface of taper pin head and the mold insert recess surface consists of the die cavity at cast convex closure position.By the cooperation of mother plate inclined pin, can further process the shape of hollow convex closure.
Described master mold respectively is provided with a glue-feeder in the both sides of product die cavity, and it is more even to make large-area sheet cavity advance glue, prevents that the dead angle from not filling the situation of glue and occuring.
Casting mold of the present utility model, product is easy to the demoulding, and shape processing has precisely improved production efficiency and the yields of product.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of product.
The specific embodiment
In order to illustrate the technical solution of the utility model and technical purpose, below in conjunction with accompanying drawing and a specific embodiment the utility model is done further introduction.
As shown in Figure 2, be the local cap of a kind of printer, they must two convex closures 1 of processing in lid surface, and described convex closure 1 is protruding upward, and inside has cavity, and an opening.
As shown in Figure 1, the casting mold of present embodiment, comprise male model and master mold, the forming surface of the forming surface of male model die cavity and master mold die cavity consists of the primary cavity of cast product profile, but for above-mentioned convex closure 1, described male model below is provided with the mold insert 2 of a protrusion male model plate datum level, described mold insert 2 bottom surfaces are provided with the forming surface die cavity of shaped article convex closure position upper surface, behind the matched moulds, described mold insert 2 probes in the master mold, and the forming surface die cavity of mold insert 2 bottoms and the die cavity of master mold consist of the die cavity at cast product convex closure position and contiguous position thereof.
The forming surface die cavity of described mold insert 2 is to being recessed on, be provided with a taper pin 3 in the described master mold, described taper pin 3 is moved up and down by the driving mechanism drive of master mold bottom, behind the matched moulds, the head of described taper pin 3 stretches into the recess of mold insert 2 forming surface die cavities, and the gap between the outer surface of taper pin 3 heads and the mold insert 2 recess surfaces consists of the die cavity at cast convex closure position.
In order to accelerate the glue speed of filling of die cavity, and avoid filling the glue dead angle, described master mold each side is provided with a glue-feeder the product die cavity, and colloid general docking site in both sides arranges steam vent when filling glue, prevents the generation of bubble.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
