Embodiment Construction

[0020] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0021] The present invention provides a kind of mold-drawing machine for casting with two speeds. During the operation of the mold-drawing machine, the starting speed of the mold-drawing can be very slow, which is beneficial to ensure the quality of the mold-drawing; Help to improve efficiency. The planetary gear train is used to make the mold lifting machine obtain a larger transmission ratio in a small space, so that the equipment structure is simple and the equipment cost is low.

[0022] As an embodiment of the present invention, the present invention provides a mold ejector for casting with two speeds, including a frame 1, a gland 2, a turntable 3, a limit nut 4, a lock nut 5, and an upper chuck 6 , chuck cover 7, lower chuck 8, fixed nut 9, screw shaft 10, duplex planetary gear 11, gland screw 12, ejector screw 13, adjusting nut 14, eject...

Abstract

A die-drawing machine for casting with two speeds, including frame, gland, turntable, limit nut, lock nut, upper chuck, chuck cover, lower chuck, fixed nut, screw shaft, double Connecting planetary gears, gland screws, ejector screws, adjusting nuts, ejector discs, molds and sand boxes, the model ejector can use the ejector discs, screw shafts, etc. to take the model out of the sand box; this The advantage of the mold ejector is that it can greatly slow down the speed of mold ejection, which is beneficial to overcome the large covering force of the molding sand on the model and effectively maintain the integrity of the mold; when the mold is ejected for a certain distance, the The received covering force becomes smaller, and the required mold-drawing force also gradually decreases. At this time, the mold-drawing machine can quickly change the mold-drawing speed to improve efficiency. Slow and then fast, so as to ensure the quality of the mold and improve the efficiency of the mold.

Description

technical field [0001] The invention relates to the field of mold manufacturing and use, and relates to a casting mold drawing tool and method suitable for different materials such as wooden molds, metal molds, and plastic molds. Specifically, it relates to a casting mold drawing tool with two speeds. machine. Background technique [0002] The model of ordinary sand casting generally uses a screw to lift the mold, and there is a screw hole on the model. When the mold is drawn, the screw is screwed into the screw hole, and then the screw is grasped to take the model out of the mold. The disadvantage of this method is that when the model is large, it is very difficult to manually lift the mold due to the large wrapping force on the model, and the speed of the mold is not easy to control, so the applicant has designed a two-speed Casting machine. Contents of the invention [0003] In order to solve the above problems. The present invention provides a kind of mold-drawing m...
