The switching mechanism of single compacting station bimodulus plate
Technical field
The utility model belongs to the Casting Equipment field, the switching mechanism of especially a kind of single compacting station bimodulus plate.
Background technology
In foundry production, need produce sand mold and following sand mold.Usually go up sand mold and make on two main frames respectively with play sand mold and finish, promptly each main frame can only produce sand mold or can only produce down sand mold, so needs to use simultaneously two main frames can in this modeling process.Like this, not only increased the whole floor space of equipment, it can not be used in the less environment in space, thereby limited the range of application of equipment, but also greatly increased the manufacturing cost of equipment, cause the rising of enterprise's production cost, make it be not suitable in medium and small foundry enterprise, using.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of reasonable in design, and floor space is little, and low cost of manufacture uses a main frame can carry out single compacting station bimodulus plate switching mechanism that upper and lower sand mold is made simultaneously.
The utility model solves its technical problem and is achieved through the following technical solutions:
The switching mechanism of a kind of single compacting station bimodulus plate, by frame, back-up sand device and compaction apparatus constitute, back-up sand device and compaction apparatus all are packed on the frame, it is characterized in that: a rotating shaft is vertically installed in the frame lower end between back-up sand device and compaction apparatus, side eccentric hinge in this rotating shaft bottom is adorned a cylinder head that is packed in a deflection oil cylinder on the frame, level installs a H type framework in this rotating shaft, the bilateral symmetry of this H type framework is provided with the framework of the pattern plate bolster that can put back-up sand device and compaction apparatus, is being fixed with back-up sand hoist cylinder and compacting hoist cylinder respectively with back-up sand device and compaction apparatus opposite position on the frame of H type framework bottom.
And described compaction apparatus below is equipped with a manipulator that can grasp sand mold.
And, but the symmetrically arranged inboard uniform saddle that is shaped on the plug-in mounting pattern plate bolster of framework of putting the pattern plate bolster of back-up sand device and compaction apparatus of described H type framework.
Advantage of the present utility model and beneficial effect are:
1. the two-way template switching mechanism of this single compacting station is rotated by rotary oil cylinder control H type framework, makes pattern plate bolster conversion mutually between back-up sand and two stations of compacting, has saved the moulding time, has improved production efficiency.
2. the utility model uses a main frame can produce upper and lower two sand molds respectively, and back-up sand and compacting can carry out simultaneously, needn't adopt other relevant apparatus of two main frames and two covers.Can reduce the manufacturing cost of entire equipment so greatly, reduce the production cost of enterprise, improve economic benefit of enterprises; Can save floor space again, it can be used in less space, thereby equipment can be widely used.
3. the utility model is simple in structure, reasonable in design, easy to manufacture, uses a main frame can make upper and lower sand mold, has saved the moulding time, has reduced the floor space of equipment, and has reduced the manufacturing cost of equipment.

The specific embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
This single compacting station bimodulus plate switching mechanism is equipped with a compaction apparatus 16 at the axis position of the frame 13 of frame-type, and this compaction apparatus below is equipped with a manipulator 14, and this manipulator can grasp sand mold 15; To being fixed with a compacting hoist cylinder 9 in the frame bottom by compaction apparatus, be fixed with a compacting lifting platform 10 on this compacting hoist cylinder, can put pattern plate bolster 12 on this lifting platform.
Be fixed with a back-up sand hoist cylinder 8 at the bottom of frame opposite side, be fixed with a back-up sand lifting platform 4 on this back-up sand hoist cylinder push rod, a coaxial pattern plate bolster 3, back-up sand sand mold 2 and the back-up sand device 1 of being equipped with successively on this lifting platform.
Innovation part of the present utility model is: a rotating shaft 5 is vertically installed in the frame lower end between back-up sand device and compaction apparatus, side eccentric hinge in this rotating shaft bottom is adorned a cylinder head 17 that is packed in a deflection oil cylinder 7 on the frame, thereby the deflection oil cylinder can drive the rotation that cylinder head is realized rotating shaft, and its anglec of rotation is 180 degree.Level installs a H type framework 6 in this rotating shaft, the bilateral symmetry of this H type framework is provided with the framework of the pattern plate bolster that can put back-up sand device and compaction apparatus, and back-up sand hoist cylinder and compacting hoist cylinder are packed in respectively on the frame with back-up sand device and the corresponding H type of compaction apparatus framework bottom.
For pattern plate bolster can be placed on the framework of H type framework template frame reposefully, but at the inboard uniform saddle 11 that is shaped on the plug-in mounting pattern plate bolster of this framework, present embodiment is eight, pattern plate bolster is inserted on these saddles by the bearing pin (not shown) respectively, and can rise to back-up sand and compacting station by the promotion of hoist cylinder.
Operation principle of the present utility model is:
Two templates that can produce upper and lower sand mold respectively are placed on respectively on two pattern plate bolsters, by the driving of back-up sand hoist cylinder and compacting hoist cylinder, lifting platform holds up pattern plate bolster, template and sandbox rises to back-up sand respectively and the compacting station carries out back-up sand and compacting.
Lifting platform descends, and the sandbox after the compacting can be stuck on the station by manipulator, and is transported on the production line; After pattern plate bolster after the back-up sand, template and sandbox drop to initial position, pattern plate bolster rides on the saddle of H type framework, the flexible H of making type framework by the rotary oil cylinder plunger rod around vertical shaft Rotate 180 degree (being depicted as postrotational oil cylinder position as Fig. 3 dotted line), makes the sandbox after the back-up sand rotate to the compaction apparatus below and carry out the compacting operation by taper roll bearing.Repeat above-mentioned steps, thereby use a main frame to carry out back-up sand and compacting simultaneously, reach the purpose of using a main frame can produce upper and lower sand mold respectively.
