Abstract

The invention belongs to the field of a turbocharger turbine and particularly relates to a mould for the turbocharger turbine. The mould for the turbocharger turbine comprises a bottom board, wherein a rotation plate is arranged on the bottom board; a lower template is arranged on the rotation plate; a sliding block is arranged on the lower template; an upper template is arranged on the sliding block; the upper template and an upper cover plate are fixed through screws; a large screw passes through the upper cover plate and is fixedly connected with the upper template and the bottom board; a mounting hole is formed in one end of the sliding block; a sliding guide pin is arranged inside the mounting hole; the top end of the sliding guide pin is fixedly arranged inside the mounting hole, and the bottom end of the sliding guide pin is inserted into an arc groove inside the rotation plate; the circumference of the bottom end of the sliding guide pin and the groove wall of the arc groove are matched through a bearing fixedly arranged on the sliding guide pin. The turbocharger turbine provided by the invention has the advantages in that a T-shaped block and the lower template are in sliding guide positioning through the sliding guide pin with a step, so that the contact area is increased, and the service life of the mould is prolonged; a rolling bearing and the rotation plate are in contact sliding guide, so that the friction is reduced, and the service life of the mould is prolonged; a wax injection opening is specially formed to be an individual pouring sleeve, so that the convenience in replacement and maintenance can be realized.

Description

Turbocharger turbine mould

Technical field

The invention belongs to field of turbochargers, specifically a kind of turbocharger turbine mould.

Background technology

Turbocharging technology is to improve engine charge density by turbocharger, can improve the combination properties such as dynamic property, economy and discharge index of engine comprehensively, to engine, injects strong impetus, and can be real play is energy-conservation, the effect of reduction of discharging.Along with the development that automobile industry is advanced by leaps and bounds, turbocharger has prospect and development space widely.And turbine is as one of core component of turbocharger, its manufacturing level, precision, will directly have influence on the development of turbocharger.

At present, for turbine manufacture, the technique generally adopting in industry is, first by the mode of melting die cast, obtains turbine blank, then blank is entered to machine adds processing.Turbine mould refers to the mould that produces wax pattern in melting die cast technique.The manufacturing cost of turbine mould is subject to its structure, material, and processing technology directly affects.

Summary of the invention

The present invention is directed to the weak point existing in above-mentioned technology, propose a kind of turbocharger turbine mould of saving mold materials cost.

The invention provides following technical scheme:

Turbocharger turbine mould, it comprises base plate, base plate is provided with rolling disc, on rolling disc, set template, on lower bolster, establish slide block, on slide block, establish cope match-plate pattern, cope match-plate pattern is fixed by screw and upper cover plate, large screw passes upper cover plate and cope match-plate pattern and base plate and fixes, described slide block one end is provided with installing hole, in installing hole, be provided with slide guide pin, the top of slide guide pin is fixed in installing hole, insert in the arc groove in rolling disc bottom, between slide guide pin bottom side face and the cell wall of arc groove by being fixed on the bearing fit on slide guide pin, lower bolster and rolling disc central authorities are provided with alignment core, in this alignment core, be provided with core retainer plate, in core retainer plate, be provided with push rod, push rod bottom is connected with depression bar by screw, push rod bottom side face is provided with spring, spring one end props up core retainer plate, the other end withstands depression bar end, depression bar is flexibly connected with base plate by pin.

The pin of described slide guide pin is provided with step with it, and step is located between lower bolster and rolling disc.

Advantage of the present invention is to adopt the slide guide pin with step to form T-shaped and lower bolster slide guide location, and the end play of console terrace and lower bolster bottom surface (approximately 0.1～0.15mm), accurately locates thereby assurance slide block is axial accurately; Adopt rolling bearing to contact slide guide with rolling disc, reduce friction, also improve die life; Increase contact area, improved die life; Adopt rolling bearing to contact slide guide with rolling disc, reduce friction, also improve die life; Casting mouth has specially been made independently sprue bush, to change, keep in repair; The design of slide guide pin, replaces straight pin in common structure, crisscross screw, and the structures such as pad, simplify mould structure, reduce processing, assembly cost; .

Fig. 2 is the structural representation of rolling disc;

Fig. 3 is the enlarged diagram of M portion in Fig. 1;

Fig. 4 is that the A-A of Fig. 3 is to view.

The specific embodiment

As shown in Figure 1, turbocharger turbine mould, it comprises base plate 1, base plate 1 is provided with rolling disc 2, on rolling disc 2, set template 3, on lower bolster 3, establish slide block 4, on slide block 4, establish cope match-plate pattern 11, cope match-plate pattern 11 is fixing with upper cover plate 5 by screw 6, large screw 8 is through upper cover plate 5, cope match-plate pattern 11, slide block 4 is fixing with base plate 1, described slide block 4 one end are provided with installing hole, in installing hole, be provided with slide guide pin 12, the top of slide guide pin 12 is fixed in installing hole, insert in the arc groove 2a in rolling disc 2 bottom, between the cell wall of slide guide pin 12 bottom side faces and arc groove 2a, by the bearing 13 being fixed on slide guide pin 12, coordinate, bearing 13 holds card 14 by E profile shaft and is fixed on slide guide pin 12, slide guide pin afterbody is processed with screwed hole, with hex head screw, be fixed in slider bottom, lower bolster 3 is provided with alignment core 10 with rolling disc 12 central authorities, alignment core 10 is by

screw

15, 16 are fixed on base plate 1, in this alignment core 10, be provided with core retainer plate 7, in core retainer plate 7, be provided with push rod 9, push rod 9 bottoms are connected with depression bar 19 by screw 20, push rod 9 bottom side faces are provided with spring 21, spring 21 one end prop up core retainer plate 7, the other end withstands depression bar 19 ends, depression bar 19 is flexibly connected with base plate 1 by pin 18, depression bar 19 outer ends are fixed with handle 17, the pin of slide guide pin 12 is provided with step 12a with it, step 12a is located between lower bolster 3 and rolling disc 2, guarantee that step end face and lower bolster bottom surface leave 0.1～0.15mm gap, with this, by step 12a, play the object of slide block axial location, cross bearing 13 cooperations and reduced frictional force, make die sinking easier, extended the life-span of rolling disc.
