Shooting cylinder

Abstract

The invention relates to a shooting cylinder, which comprises a cylinder body, wherein a sand feeding opening is arranged at the upper part of the cylinder body; a shooting head is connected at the lower part of the cylinder body; a cover body is arranged at the upper part of the cylinder body; a sealed cavity capable of storing resin sand is arranged at the inner part of the cylinder body through the cover body; and a humidifying device is connected inside the sealed cavity. By adding the cover body at the upper part of an existing shooting cylinder, certain resin sand, especially inorganic resin sand, which is sensitive to the humidity, is ensured to be in the required humidity during the core manufacturing process; the shooting cylinder is not affected by external factors such as environment, time and the like; the requirements on core manufacturing process can be met; and the core manufacturing can be accomplished in an optimal state.

Description

Technical field [0001] The present invention involves a core -making auxiliary device, especially a spinage. Background technique [0002] The tube is the main component of the inductive machine, and its role is to store resin sand at each core.like figure 1 It shows that the spinage includes a cylinder 1 ', the upper part of the cylinder 1 is added with sand port 10', the lower part of the cylinder 1 'is connected to the ejection head 2', and the raw plate 20 'is set on the ejection head 2'.20 'Connect a number of shooting mouth 21'.When the core of the core is required, the resin sand 8'from the cylinder 1 'passing through the ejection head 2' and the ejection mouth 21 'into the core box 9', and then move to the sand adding station to add the next time the sand is used for the next time the sand is used.Resin sand 8 'and wait for the next time the sand.The current situation is that when the next time the resin sand 8 "is added, the addition of the sand port 10 'of the entire tu...

AI Technical Summary

Problems solved by technology

The present situation is that after adding the resin sand 8' for sand shooting next time, the sand filling port 10' of the whole cylinder 1' is open, that is, it is in contact with the air, and it takes a while to shoot sand. If the resin sand 8' (such as inorganic resin sand) stored at this time needs good humidity to ensure its core-making effect, then long-term contact with drier air will take away the moisture of the resin sand 8' and affect the core-making effect. core effect

In this way, the open sand filling port of the injection cylinder will cause some moisture-sensitive resin sand in the cylinder to lose moisture, which will affect the execution effect
