Sand-leakage-free shooting plate device for casting core shooting

Abstract

The invention discloses a sand-leakage-free shooting plate device for casting core shooting, and belongs to the technical field of core shooters. The sand-leakage-free shooting plate device for casting core shooting comprises a shooting plate and a reverse ejection plate device, wherein the reverse ejection plate device is arranged on the shooting plate, and the reverse ejection plate device comprises a plurality of reverse ejection rods; the bottoms of the plurality of reverse ejection rods penetrate through the shooting plate and are exposed out of the shooting plate, the plurality of reverse ejection rods are in sliding fit with the shooting plate, and the tops of the plurality of reverse ejection rods are fixedly connected with a reverse ejection plate; a plurality of sand sealing needles are fixedly arranged on the reverse ejection plate; a plurality of elastic assemblies are further fixedly arranged on the shooting plate upwards, and the plurality of elastic assemblies penetrate through the reverse ejection plate; the reverse ejection plate can slide on the plurality of elastic assemblies under stress; shooting openings are formed in the bottoms of the sand sealing needles on the shooting plate; and the sand sealing needles can seal the corresponding shooting openings. The sand-leakage-free shooting plate device can solve the problem of waste caused by the fact that precoated sand is scattered from the shooting openings under the dynamic condition in an existing shooting plate device for a casting core shooter.

Description

technical field [0001] The invention belongs to the technical field of core shooting machines, in particular to a non-leaking sand shooting plate device for casting core shooting machines. Background technique [0002] The shooting plate device is one of the important components of the foundry core shooting machine. An existing casting core shooter shooting plate device such as figure 1 As shown, it is mainly composed of shooting plate 1, spacer 2, and sand retaining plate 3. The entire shooting plate device is installed on the shooting head 4, the shooting port 1 is opened, and the sand retaining plate 3 is fixed on the spacer 2. Block the nozzle on the shooting plate 1, the shooting head 4 is fixed on the outer edge of the shooting plate 1 and forms a cavity with the shooting plate 1, and the coated sand is installed in the cavity. Because the coated sand inside the nozzle does not flow out automatically due to the accumulation angle principle, but when the shooting plat...

AI Technical Summary

Problems solved by technology

Because the coated sand inside the nozzle does not flow out automatically due to the accumulation angle principle, but when the shooting plate device moves together with the nozzle, the coated sand inside the nozzle will be scattered from the nozzle due to vibration (10 times each time) ~100 grams), which not only causes a lot of waste of coated sand, but also heats and solidifies the coated sand after it is scattered on the mold, which increases the workload of subsequent manual cleaning
