The utility model discloses a top core function merges with the exhaust function, has cancelled the ejector pin of original installation in the core box mould benevolence, and the psammitolite surfacing that makes out like this does not need personnel to handle, the utility model discloses avoided superficial sand to produce when promoting the psammitolite quality.
Description
Technical Field
The utility model relates to a triethylamine coremaking technical field especially relates to a core box ejector pin with exhausting function.
Background
In the process of making the core by using the triethylammonia, the exhaust of the core box in the inner cavity of the core box must be arranged in the sand shooting and hardening processes, so that the filling and the full hardening of the sand core are ensured. The hardened and formed sand core needs to be ejected out of the cavity of the core box by using an ejector rod. Both the exhaust device and the core ejecting device need to be designed in the mold core. Therefore, the surface of the sand core is reduced in quality due to the ejector rod and the exhaust, the surface is uneven, the sand core needs to be repaired by personnel, and the labor intensity is increased. The surface layer of the sand core is damaged in the repairing process, and floating sand is generated. Causing troubles and quality hidden troubles for the subsequent procedures.
Disclosure of Invention
The utility model discloses aim at solving prior art's not enough, and provide a core box ejector pin with exhaust function.
The utility model discloses a realize above-mentioned purpose, adopt following technical scheme: the utility model provides a core box ejector pin with exhausting function, includes core box mould benevolence, is equipped with a plurality of air release plugs on the core box mould benevolence, and core box mould benevolence below is equipped with first mounting panel, is equipped with a plurality of cavity ejector pins with the air release plug one-to-one on the first mounting panel, and cavity ejector pin top is connected with the air release plug, and cavity ejector pin lower extreme and outside air intercommunication, first mounting panel below are equipped with the second mounting panel, are equipped with the ascending mechanism of a plurality of vertical ejector pins on the second mounting panel, and the ascending mechanism.
The hollow ejector rod is vertically arranged on the first mounting plate.
The top end of the hollow ejector rod is clamped with the exhaust plug.
The vent plug is a net-shaped vent plug.
The push rod lifting mechanism is a hydraulic cylinder.
The utility model has the advantages that: the utility model discloses a top core function merges with the exhaust function, has cancelled the ejector pin of original installation in the core box mould benevolence, and the psammitolite surfacing that makes out like this does not need personnel to handle, the utility model discloses avoided superficial sand to produce when promoting the psammitolite quality.
