Abstract
The utility model relates to a centrifugal casting machine with no crucibles, comprising a drive motor and a centrifugal revolving rack arranged on the axis of the drive motor. The utility model is characterized in that a die holder is arranged on one end of the centrifugal revolving rack. The die which comprises the cavity of a casting and a melt mouth is arranged in the die holder. The other end of the centrifugal revolving rack is provided with a counterweight. The utility model makes the one time investment of equipment reduced, and simultaneously expensive material consuming crucibles are saved. Thereby, the production cost is decreased. In addition, the utility model has no limit of the quantity of raw materials, so the utility model is suitable for single or small batch production. Simultaneously, the quality of the products can not be affected due to the drop of temperature. The rate of finished products can be achieved by more than 90 percent.
Description
The utility model is a kind of small-sized casting equipment, particularly a kind of centrifugal casting equipment that is used for jewellery processing.
Be used for the jewellery method for processing now and have two kinds, a kind of is when producing in enormous quantities, adopt big mould casting, the general eddy-current heating centrifugal casting machine that uses, its operation principle is that crucible and mould together are installed on the pivoted arm of centrifuge, by induction coil the raw material in the crucible is heated to fusing, starter motor rotates then, by centrifugal force raw material melted is cast in the mould.There is following shortcoming in this machine: one-time investment is bigger, need ten surplus ten thousand yuan; Consumable material costliness (as long as platinum crucible one is about 700 yuan); Once the raw material of Tou Ruing can not so can only be applicable to batch process, be processed and can not be suitable for single very little.Another kind is small lot or single only production, it is with after the raw material fusing, be pressed into mould with yellow mud, though this method can be used for the production and processing of small lot or single jewellery, but because the temperature requirement of platinum processing is higher, and temperature descends comparatively fast in the process that yellow mud is pressed into, so the yield rate of processing is very low, makes production cost high.
The purpose of this utility model provides a kind of novel from property formula casting machine, and it can overcome existing shortcoming in the prior art, reduces investment, reduces cost, and is fit to single small lot batch manufacture.
The purpose of this utility model is achieved in that it comprises drive motors and the centrifugal pivoted frame that is installed on the drive motors axle, it is characterized in that die frame being installed at an end of centrifugal pivoted frame, mould is placed in the die frame, comprise the die cavity and the melt mouth of foundry goods in the mould, the other end of pivoted frame is equipped with counterweight.
Motor shaft in the above-mentioned casting machine is horizontal direction (being that pivoted frame rotates at vertical plane), and the tangential force in order to prevent to start spills melt, tilts to place between die frame and the pivoted frame, and the melt mouth of mould tilts to rotation direction.
Motor shaft also can be vertical direction (being that pivoted frame rotates at horizontal plane), and the two ends of pivoted frame to the both sides distortion, form the inclined-plane respectively, makes the superincumbent die frame of installation inclined.
Die frame and can be fixed installation between the frame specially also can rotate installation, and promptly die frame can turn an angle on pivoted frame, can prevent that like this melt spills outside the mould rotating at the beginning, starts the back mould and becomes and be parallel to the pivoted frame axis.
The counterweight that is installed in pivoted frame one end also can replace with a die frame identical with the other end, so not only can play the effect of counterweight, also can operate together by two moulds simultaneously, can increase work efficiency.
The utility model is loaded on raw material in the melt mouth of mould, adopts spray gun or electrode holder that raw material is carried out flame heat, treat that raw material is melt and dissolved after, starter motor makes centrifugal pivoted frame begin rotation, and quicken gradually, melt and dissolved raw material promptly enters under action of centrifugal force in the die cavity of mould, casting forming.
The utility model has the advantages that: small mould is directly installed on the cursor, use flame heat, saved expensive high-frequency induction heating apparatus, the one-time investment of equipment is reduced, has save expensive consumable material crucible simultaneously, production cost must be descended, in addition the utility model for raw material what without limits, so can be fit to only single or small lot batch manufacture, can not influence the quality of product simultaneously owing to temperature descends, yield rate is reached more than 90%.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail.
Fig. 1 is that motor shaft of the present utility model is the structural representation of horizontal embodiment.
Fig. 2 is the A-A cutaway view among Fig. 1.
Fig. 3 is the side view of Fig. 1.
Fig. 4 is that motor shaft of the present utility model is the structural representation of the embodiment of vertical configuration.
Fig. 5 is that B among Fig. 4 is to view.
1 is drive motors among the figure, as seen from Figure 1, motor shaft is a horizontal direction, the centrifugal pivoted frame 2 that is fixedly mounted on the motor shaft rotates at vertical plane with motor shaft, end at pivoted frame is equipped with die frame 3, die frame on pivoted frame, is laid mould 4, as seen from the figure by fixed by nut in die frame, be provided with melt mouth 5 and die cavity 6 in the mould, there is passage to communicate between its face, as seen from Figure 3, tilts between die frame and the pivoted frame, pivoted frame is rotated counterclockwise, the melt mouth is towards the rotation direction of pivoted frame, and is excessive for prevent that pivoted frame from vibrating in rotation process, with fixed by nut counterweight 7 is installed at the other end of pivoted frame.
Motor shaft 1 is for vertically upward (downwards also can) among Fig. 4, centrifugal pivoted frame 8 is installed on the motor shaft, a die frame 9 is respectively installed at the two ends of pivoted frame, die frame is inserted in the hole of pivoted frame, nut 10 is equipped with in the bottom, make between die frame and the pivoted frame and can relatively rotate, a fixture block 11 is arranged on pivoted frame, be used to limit the rotational angle of die frame, two die frames can be mutually as counterweight, also can carry out melt processing simultaneously, the two ends of centrifugal pivoted frame to both sides distortions, are skewed respectively, die frame be the melt mouth up, be convenient to the melt operation on the one hand, can reduce the outer of melt when starting simultaneously and spatter.After startup was finished, because action of centrifugal force, die frame and mould changed into level, and die frame also can be fixed on the pivoted frame; Also can be at pivoted frame one end installation mold frame, the other end is installed balancing weight.
