Abstract
The utility model discloses the rotary type vacuum negative pressure device for shaping investment pattern, it comprises vacuum tank (1) and is opened in the through hole (2) of vacuum tank one side, described vacuum tank inner bottom part central authorities are provided with rotating cylindrical base (3), the central authorities of described cylindrical base are opened in arc groove (4), and the inwall of described arc groove is provided with some retainer springs (5) that extend to arc groove center.The beneficial effects of the utility model are when vacuumizing, to make wax-pattern die cavity follow cylindrical base rotation, make wax liquid because the effect of centrifugal force is fully packed into each fine recesses of die cavity, shaping investment pattern is complete, qualification rate is high, it is unstable when arc groove can be avoided the rotation of wax-pattern die cavity, retainer spring can provide stable chucking power to wax-pattern die cavity, stability when graininess projection can further strengthen the rotation of wax-pattern die cavity.
Description
Technical field
The utility model relates to vacuum negative pressure device, relates in particular to the rotary type vacuum negative pressure device for shaping investment pattern.
Background technology
" lost wax casting " is a kind of conventional forging type, first makes the pattern of workpiece, then wax injected to pattern, then etc. wax wax pattern is taken out after cooling.In order to obtain the comparatively needed wax-pattern of delicate workpieces, pattern often has complicated meticulous structure, is specially various tiny groove, projection and gap etc. on mould.At wax, inject after these tiny structures, must guarantee that wax is abundant to the filling in these gaps, just can make the fine degree of the wax-pattern made meet the requirements.In existing production procedure, employing is injected after pattern at wax, then pattern is put into the cavity of negative pressure of vacuum equipment, makes it in negative pressure state, utilize that pattern external and internal pressure is poor to be pressed to the wax in pattern in each fine recesses and gap, thereby guarantee that wax is abundant to the filling in these gaps.But in this process, the residual wax on pattern surface tends to drip spatters on the housing surface of negative pressure equipment, thereby pollutes.Because cavity depth is large, when clean, be difficult to burnisher to extend into its inboard, so often time-consuming to cleaning of cavity.
Utility model content
The technical problems to be solved in the utility model is that the existing vacuum negative pressure device for shaping investment pattern causes that in the process vacuumizing wax liquid splashes, and pollutes vacuum chamber, and a kind of rotary type vacuum negative pressure device for shaping investment pattern is provided for this reason.
The technical solution of the utility model is: for the rotary type vacuum negative pressure device of shaping investment pattern, it comprises vacuum tank and is opened in the through hole of vacuum tank one side, described vacuum tank inner bottom part central authorities are provided with rotating cylindrical base, the central authorities of described cylindrical base are opened in arc groove, and the inwall of described arc groove is provided with some retainer springs that extend to arc groove center.
The improvement of such scheme is that described arc groove bottom is provided with some graininess projections.
The beneficial effects of the utility model are when vacuumizing, to make wax-pattern die cavity follow cylindrical base rotation, make wax liquid because the effect of centrifugal force is fully packed into each fine recesses of die cavity, shaping investment pattern is complete, qualification rate is high, it is unstable when arc groove can be avoided the rotation of wax-pattern die cavity, retainer spring can provide stable chucking power to wax-pattern die cavity, stability when graininess projection can further strengthen the rotation of wax-pattern die cavity.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model;
In figure, 1, vacuum tank, 2, through hole, 3, cylindrical base, 4, arc groove, 5, retainer spring, 6, graininess projection.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, the utility model comprises vacuum tank 1 and is opened in the through hole 2 of vacuum tank one side, described vacuum tank inner bottom part central authorities are provided with rotating cylindrical base 3, the central authorities of described cylindrical base are opened in arc groove 4, and the inwall of described arc groove is provided with some retainer springs 5 that extend to arc groove center.
Cylindrical base has motor to drive with specific rotating speed rotation, motor can be built in cylindrical base, also can be placed on vacuum tank, by holding wire, connects, the size of arc groove and the wax-pattern die cavity that will put into are suitable, also can be a bit larger tham wax-pattern die cavity to be processed, retainer spring can provide chucking power to putting into the wax-pattern die cavity of arc groove, and retainer spring is preferably symmetrical arranged in pairs, such as four, be evenly distributed in arc groove,, or two, six, eight can.Retainer spring can be made accommodation according to the size of wax-pattern die cavity on the one hand, and stable chucking power is provided all the time, has strengthened on the other hand the adhesion of wax-pattern die cavity and arc groove.
In order further to strengthen the adhesion of wax-pattern die cavity and arc groove, can be provided with in the bottom of arc groove some graininess projections, increase the stiction of wax-pattern die cavity and arc groove.Graininess projection can be some independent individualities that disperse, and also can join together.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
