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
The invention provides a mold stripping machine with two speeds for casting. The mold stripping machine comprises a rack, a gland, a rotary disc, a limiting nut, a locking nut, an upper chuck, a chuckcover, a lower chuck, a fixing nut, a lead screw shaft, a duplex planetary gear, a gland screw, a mold stripping screw, an adjusting nut, a mold stripping disc, a casting mold and a sand box. According to the mold stripping machine, a model can be taken out of the sand box through the mold stripping disc, the lead screw shaft and the like. The mold stripping machine has the advantages that the mold stripping starting speed can be greatly decreased, thus the large coating force of molding sand to the model can be overcome advantageously, and the integrity of the casting mold is effectively maintained; and after mold stripping is conducted by a certain distance, the coating force borne by the model is decreased, the required mold stripping force is also decreased gradually, at the moment, the mold stripping speed of the mold stripping machine can be changed rapidly, the efficiency is improved, thus the mold stripping machine has the characteristics that the mold stripping speed can be decreased firstly and then increased according to the actual situation, and as a result, the mold stripping quality can be ensured, and the mold stripping efficiency can also be improved.
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...
