Description

Technical Field

[0001] The utility model relates to a large-scale rolling mill bearing seat mold, in particular to a prevention and control embedded part casting device, belonging to the technical field of casting. Background Art

[0002] Embedded parts for prevention and control technology support are important parts in large-scale projects, involving air defense, bridges, buildings and other fields. They are an important part to ensure the overall stability, safety and overall performance of the project. This type of parts weighs about 50 tons and requires 100% ultrasonic flaw detection and magnetic particle flaw detection according to level 2 in JB / T5000.14. Due to the structure of the casting, it is very easy to produce L-shaped fillet cracks and flat surface warping during casting production, resulting in serious quality problems such as unqualified flaw detection. Utility Model Content

[0003] The technical problem to be solved by the utility model is: to overcome the shortcomings of the prior art and provide a casting device for preventing and controlling embedded parts, which ensures the internal quality of the casting by arranging a full circle of subsidies and anti-cracking ribs and avoids the occurrence of cracks at the outer rounded corners.

[0004] The technical solution adopted by the utility model to solve the technical problem is:

[0005] A prevention and control embedded part casting device comprises a sand box and a mold, wherein the mold is arranged in the sand box, anti-cracking ribs are arranged at the rounded corners on the outside of the mold, a full circle of patches are arranged around the inner hole of the mold, a first external cooling iron is arranged at the bottom of the mold and around the bottom, and a second external cooling iron is arranged around the outside of the mold.

[0006] The inner hole of the mold is provided with an internal sand mold.

[0007] A heat-insulating riser is arranged on the top of the mold.

[0008] There are four second outer chillers, which are evenly distributed at the center positions of the four sides of the outside of the mold.

[0009] The positive beneficial effects of the utility model are:

[0010] 1. The utility model changes the inner hole structure of the mold, sets a full circle subsidy, and cooperates with the use of external cold iron, which greatly reduces the workload of the finishing process, effectively saves production costs, shortens the construction period, improves production efficiency, and is easy to promote.

[0011] 2. The utility model avoids the problem of cracks in the L-shaped fillet during casting by arranging anti-crack ribs at the fillet outside the mold, thereby improving the quality of the casting and making the casting meet the requirements of level 2 ultrasonic and magnetic particle inspection in JB / T5000.14. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a schematic diagram of the structure of the utility model;

[0013] Figure 2 for Figure 1 A cross-sectional view of

[0014] Among them: 1-mold, 2-anti-cracking ribs, 3-second outer chiller, 4-first outer chiller, 5-insulation riser, 6-full circle subsidy, 7-internal sand core. DETAILED DESCRIPTION

[0015] The utility model is further explained and illustrated below in conjunction with the accompanying drawings:

[0016] For example, see Figure 1-Figure 2 A prevention and control embedded part casting device includes a sand box and a mold 1. The mold 1 is arranged in the sand box, anti-cracking ribs 2 are arranged at the rounded corners on the outside of the mold 1, a full circle of patches 6 are arranged around the inner hole of the mold 1, a first external chiller 4 is arranged at the bottom of the mold 1 and around the bottom, and a second external chiller 3 is arranged around the outside of the mold 1.

[0017] An inner sand mold 7 is arranged in the inner hole of the mold 1 .

[0018] A heat-insulating riser 5 is provided on the top of the mold 1 .

[0019] There are four second outer chillers 3 , which are evenly distributed at the center positions of the four sides of the outside of the mold 1 .

[0020] In the above description, the scheme adopts the whole real sample + internal sand core; the scale is reasonably set according to the product size (1.8%-2.0%); the inner hole structure is changed, and a full circle of internal stickers are set; anti-cracking ribs are set at the outer fillet, and the process risers are single risers (Φ500-Φ1000) at intervals of 300~350. The bottom uses 300*300*300~450*450*450 external cooling iron for quenching to form a sequential solidification law, which ensures the internal quality of the casting and improves the shrinkage compensation efficiency of the riser, avoiding cracks in the outer fillet.

[0021] When making the exterior, place the actual model, anti-cracking ribs, special external chiller, and runner according to the process requirements, then knock out the exterior shape, and make the internal sand core and fix it in the cavity according to the process requirements; place the upper box with the open riser according to the process requirements and then knock out the upper box; finally, paint the upper box and the cavity, then buckle the box and wait for pouring; after molding, the anti-cracking ribs and the entire circle of subsidies need to be removed.

[0022] The utility model changes the inner hole structure of the mold, sets a full circle subsidy, and cooperates with the use of external chiller, which greatly reduces the workload of the finishing process; by setting anti-crack ribs at the fillet on the outside of the mold, the problem of cracks in the L-shaped fillet during casting is avoided, the quality of the casting is improved, the construction period is shortened, and the cost is saved.
