Abstract
The utility model discloses a multipoint local extrusion mechanism of a CVT gearbox shell die-casting die. The multipoint local extrusion mechanism of the CVT gearbox shell die-casting die comprises an extrusion oil cylinder (1), a connecting block I (2), a fixing board (3), extrusion pins (4), a connecting block II (5) and extrusion pin sleeves (6). The extrusion oil cylinder is arranged on the back face of a movable die frame (9). The connecting block I is arranged in front of the extrusion oil cylinder and fixedly connected with a piston rod of the extrusion oil cylinder. The fixing board is arranged in front of the connecting block I and two through holes arranged side by side are formed in the middle of the fixing board. The number of the extrusion pins is two and the two extrusion pins penetrate through the through holes of the fixing board respectively from the rear side of the fixing board and are located. The connecting block II is arranged in front of the fixing board and two through holes arranged side by side are formed in the middle of the connecting block II. The extrusion pins are sleeved with the connecting block II which is fixedly connected with the connecting block I. The extrusion pins are sleeved with the extrusion pin sleeves. According to the multipoint local extrusion mechanism of the CVT gearbox shell die-casting die, local extrusion and shrinkage complementation is conducted on a structure closely adjacent to a main oil channel of a CVT gearbox shell and the quality of a product is improved.
Description
Technical field
The utility model relates to a kind of local pressing mechanism of pressure-casting mold of speed changer shell, is specifically related to a kind of pressing mechanism of die casting CVT case of transmission multi-point partial extruding, belongs to metal casting technical field.
Background technology
Local extruding is to have loose, shrinkage cavity for the thick large part of foundry goods, by supercharging, can not get rid of and the specific process taked.Principle is to exist mould place loose, shrinkage cavity to install squeeze pin additional in the thick large part of foundry goods, squeeze pin is connected by hydraulic cylinder and machine, according to the needs of foundry goods, setting pressure and time, during production, when injection supercharging starts, squeeze pin starts action, carry out part extruding feeding, casting quality is improved.
Automotive transmission is key position parts on automobile, and CVT speed changer is a future automobile power train unification important developing direction; CVT speed changer, i.e. electric-controlled mechanical ST, its structure is simpler than traditional speed changer, and volume is less, mainly by driven wheel and metal, brings the stepless variation that realizes speed ratio.
Although CVT speed changer structure is simpler than traditional speed changer, because volume is little, cause inner space compact, the main oil gallery on its housing must be adjacent very near because of product function requirement, and precasting causes internal shrinkage larger completely, cannot realize batch product requirement of product.
The local pressing mechanism of traditional die casting, is generally only used a squeeze pin, just inapplicable for the adjacent very near situation in this duct.
Summary of the invention
For the problems referred to above, the utility model provides a kind of multi-point partial pressing mechanism of CVT pressure-casting mold of speed changer shell, can carry out part extruding feeding for the adjacent very near structure of CVT case of transmission main oil gallery, improve the quality of products, and can realize batch product requirement of product.
For achieving the above object, the utility model comprises extrusion oil cylinder, contiguous block I, fixed head, squeeze pin, contiguous block II and extruding guide, and whole pressing mechanism is built in the framed inside of dynamic model;
Extrusion oil cylinder is arranged on the framed back side of dynamic model, with the framed vertical fixed installation of dynamic model (following direction of take extrusion oil cylinder place is rear);
Contiguous block I is arranged on the place ahead of extrusion oil cylinder, is fixedly connected with the piston rod of extrusion oil cylinder;
Fixed head is arranged on the place ahead of contiguous block I, is provided with two through holes side by side in the middle of it, and through hole rear is provided with step in location;
Squeeze pin afterbody is provided with the outer step in location, is set to two, and self-retaining plate rear penetrates in fixed head through hole respectively, and its afterbody is located outer step and is positioned in the location at fixed head through hole rear in step;
Contiguous block II is arranged on the place ahead of fixed head, is provided with and allows two squeeze pins pass and exhausting hole in the middle of it, and contiguous block II is enclosed within on squeeze pin and with contiguous block I and is fixedly connected with;
Extruding guide is sleeved on squeeze pin.
Further, contiguous block I is fixedly connected with by bolt, nut with contiguous block II.
Compared with prior art, the whole framed inside of dynamic model that is built in of the utility model, moves more stable; Owing to by contiguous block I and contiguous block II, two place's squeeze pins being fixed together, thereby while making to push, double-pin is worked simultaneously, has solved and has arranged the problem of two oil cylinder insufficient spaces, and increased amount of compression, has guaranteed oil duct interior solid.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, extrusion oil cylinder, 2, contiguous block I, 3, fixed head, 4, squeeze pin, 5, contiguous block II, 6, extruding guide, 7, bolt, 8, nut, 9, dynamic model is framed.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, the multi-point partial pressing mechanism of this CVT pressure-casting mold of speed changer shell comprises extrusion oil cylinder 1, contiguous block I 2, fixed head 3, squeeze pin 4, contiguous block II 5 and extruding guide 6, and whole pressing mechanism is built in framed 9 inside of dynamic model;
Contiguous block I 2 is arranged on the place ahead of extrusion oil cylinder 1, is fixedly connected with the piston rod of extrusion oil cylinder 1;
Fixed head 3 is arranged on the place ahead of contiguous block I 2, is provided with two through holes side by side in the middle of it, and through hole rear is provided with step in location;
Contiguous block II 5 is arranged on the place ahead of fixed head 3, is provided with and allows two squeeze pins 4 pass and exhausting hole in the middle of it, and contiguous block II 5 is enclosed within on squeeze pin 4 and with contiguous block I 2 and is fixedly connected with;
Extruding guide is sleeved on squeeze pin.
Further, for the ease of safeguarding and changing squeeze pin 4, contiguous block I 2 is fixedly connected with by bolt 7, nut 8 with contiguous block II 5.
Before use, extrusion oil cylinder 1 oil connection is connected to the engine oil pressure interface of lathe, and the setting pressure and the time that local extruding order are set in PLC process and need according to foundry goods; After supercharging starts, extrusion oil cylinder according to PLC order start working, promote two place's squeeze pins 4 and adjacent very near oil duct top boss carried out to secondary extrusion simultaneously, thereby feeding is carried out in oil duct inside, increase the compactness of inside, oil duct position, improve the quality of products.
