Abstract

The utility model relates to a kind of thin-walled planet carriers to cast tooling: including sandbox, loam core, sprue, ingate, filter screen, chill core print pipe, chill rest pad and chill briquetting, sprue is through the ingate in filter screen connection sandbox, ingate is connected to planet carrier type chamber by bottom, chill rest pad is set below the evagination step of planet carrier type chamber, planet carrier type chamber wears the hole inner wall setting chill core pipe for the core that grafts clay, and is pressed with chill briquetting on the former of planet carrier type chamber upper end.Its structure is simple, can effectively stable sand mold, avoid shrinkage porosite, improve casting quality.

Description

A kind of thin-walled planet carrier casting tooling

Technical field

The utility model relates to casting field, specifically a kind of thin-walled planet carrier casts tooling.

Background technique

Important component of the planet carrier as speed reducer, generallys use casting and forming, and the existing sand mold that directlys adopt cooperates Loam core forming recess complete casting, since its structure is complicated, at more thin-walled, at outer lug boss without support, sand mold easily collapses, molten iron Cooling there are shrinkage porosite phenomenons, influence planet carrier casting quality and qualification rate.

Summary of the invention

It is simple that the utility model provides a kind of structure, can effectively stable sand mold, avoid shrinkage porosite, improve the thin of casting quality Wallflow carrier casts tooling.

The technical solution adopted in the utility model is:

A kind of thin-walled planet carrier casts tooling, it is characterised in that: including sandbox, loam core, sprue, ingate, filter screen, Chill core print pipe, chill rest pad and chill briquetting, sprue is through the ingate in filter screen connection sandbox, and ingate is by bottom It is connected to planet carrier type chamber, chill rest pad is set below the evagination step of planet carrier type chamber, is set at planet carrier type cavity thin-wall thermal center Chill core pipe is set, is pressed with chill briquetting on the former of planet carrier type chamber upper end.

The sprue, ingate are ceramic tube.

The chill rest pad fitting evagination step is expert at the thermal center of carrier type chamber.

The utility model sets planet carrier type chamber upper end, outer lug boss step thermal center, loam core perforation using chill core needle Pressing plate, rest pad and pipe structure are counted, effectively ensures the stabilization of monolithic devices chamber Yu loam core structure, prevents sand mold loose and casting contracting Pine improves castability and yield rate.

Detailed description of the invention

FIG. 1 is a schematic structural view of the utility model.

In figure: planet carrier type chamber 1, loam core 2, sprue 3, ingate 4, filter screen 5, chill core print pipe 6, chill rest pad 7, chill briquetting 8.

Specific embodiment

It is described further below in conjunction with drawings and examples.

Shown in Fig. 1: a kind of thin-walled planet carrier casting tooling include sandbox, loam core 2, sprue 3, ingate 4, filter screen 5, Chill core print pipe 6, chill rest pad 7 and chill briquetting 8, sprue 3 are connected to the ingate 4 in sandbox, ingate through filter screen 5 4 are connected to planet carrier type chamber 1 by bottom, and chill rest pad 7, chill rest pad patch are arranged below the evagination step of planet carrier type chamber 1 It closes evagination step to be expert at the thermal center of carrier type chamber, setting chill core pipe 6 at planet carrier type cavity thin-wall thermal center, on planet carrier type chamber Chill briquetting 7 is pressed on the former of end, sprue, ingate are ceramic tube.
