Technical Field

[0001] The utility model relates to the technical field of casting demoulding, in particular to a noise reduction, crushing and demoulding device for castings. Background Art

[0002] Castings are metal shaped objects obtained by various casting methods, that is, the smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods, and then cooled and polished to obtain objects with a certain shape, size and performance.

[0003] Demolding is the step of separating the casting from the mold after casting is completed. Currently, when the casting is crushed to demold, it is necessary to use hydraulic equipment to squeeze the mold to break it, thereby completing the demolding of the casting. However, when the mold is crushed to demold, a large noise is generated, causing noise pollution, and the practicality is low.

[0004] In view of this, we propose a noise reduction, crushing and demoulding device for castings. Utility Model Content

[0007] A hydraulic cylinder is fixedly installed at the center of the bottom of both sides of the soundproof box, and a driving shaft is fixedly installed at one end of the piston rod of the hydraulic cylinder extending into the soundproof box, and an extrusion head for extruding the casting mold is welded and fixed at one end of the driving shaft away from the hydraulic cylinder;

[0008] The soundproof box is provided with a rectangular cavity at one end facing the door, and a sound insulation layer is fixedly installed in the rectangular cavity. Attraction plates are equidistantly constructed on both sides of the soundproof box, on the side away from the door, and on one side of the two doors. A handle is fixedly installed in the center of one side of the door, and a sound absorption cavity is provided in the center of one side of the attraction plate.

[0009] Preferably, an exhaust port for fixing an exhaust scoop is centrally provided on a side of the top of the soundproof box away from the box door, and a delivery pipe is connected to one side of the exhaust scoop.

[0010] Preferably, one end of the delivery pipe away from the exhaust scoop is connected to an exhaust fan fixedly installed at the top center of the sound insulation box, and the exhaust of the exhaust fan is connected to a delivery hose.

[0011] Preferably, a slider is centrally configured at one end of the extrusion head, and guide grooves adapted to the slider are centrally provided on both sides of the bottom end of the sound insulation box.

[0012] Preferably, guide keys are centrally constructed on both sides of the sliding block, and positioning grooves adapted to the guide keys are centrally opened on both sides of the guiding groove.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. Thanks to the setting of the soundproof box and two door panels, when two hydraulic cylinders push two extrusion heads installed at one end of two drive shafts to move, the mold can be extruded and damaged from both sides. During extrusion, the soundproof box and two door panels are used to block the noise, thereby improving the noise isolation effect through the soundproof layer installed in the soundproof box.
