Abstract
The invention discloses a V method modeling and lost foam compaction device, which comprises a chassis, wherein the chassis consists of wheels, a bearing block, rails, a frame and axles; a lifting system is arranged on the frame; a vibration system comprising a vibration motor and a vibration mesa is connected on the lifting system; and an operating mechanism capable of moving the vibration system is arranged on the frame. The vibration motor is arranged on the vibration mesa, and compaction of a sand box is realized by vibration of the vibration motor. The lifting system lifts the vibration mesa to prop on the bottom surface of a sand adding device to vibrate the sand box so as to solve the problems of flying dust during adding sand, all-directional movement and damage to a die over time due to resonance generated by a model and the vibration mesa during compaction, non-uniform compaction, insufficient hardness and the like. Compared with the prior art, the V method modeling and lost foam compaction device has the advantages that: the power of a motor is reduced by about 20 percent, the vibration time is reduced by about 30 percent, and the hardness of the sand in the sand box is improved by about 12 percent.
Description
Technical field
The invention belongs to the casting mould technical field, be specifically related to a kind of device that is used for moulding and the jolt ramming of disappearance sand case.
Background technology
In the existing V method moulding industry, mostly be to make a plain bumper or vibration chassis, the model that has covered film is placed on the vibration table, put sandbox above, in sandbox, add sand, and then jolt ramming.Though this method is feasible, have following problem at work: 1, sand and dust fly upward in the process of adding sand; 2, fix with alignment pin between model and the vibration table, the gap is bigger, about model can be followed during vibration, move left and right, produces resonance sometimes, causes jolt ramming degree inequality, and hardness is not enough; 3, because model moves up and down, cause model damage to a certain degree.
Summary of the invention
The objective of the invention is to solve the problems of the technologies described above, moulding of a kind of V method and disappearance mould jolt ramming device are provided.
V method of the present invention moulding and disappearance mould jolt ramming device comprise the chassis of being made up of wheel, bearing block, track, vehicle frame and axletree, described vehicle frame is provided with hoisting system, connection is provided with vibrational system above the described hoisting system, and vehicle frame is provided with the travelling mechanism that described vibrational system is moved.
Wherein, described hoisting system is air spring or hydraulic jack, the flexible lifting by air spring or hydraulic jack or put down vibrational system.
Described vibrational system involving vibrations motor and vibration table, vibrating motor is installed on the vibration table, realizes the jolt ramming of sandbox by the vibration of vibrating motor.Described vibrating motor is no less than 1, and preferably, vibrating motor is 2 or 3.
Further, between described vehicle frame and vibration table, be provided with the safety margins device.Described safety margins device is chassis alignment pin and the mutually corresponding with it chassis positioning sleeve that is arranged on the vibration table that is arranged on the vehicle frame.Described safety margins device can also be corresponding mutually optoelectronic induction components and parts.
Simultaneously, also on described vibration table, be provided with positioning element.Described positioning element is mould alignment pin or optoelectronic induction components and parts.
The present invention is by the vibration chassis, rely on hoisting system to lift vibration table, withstand on the sanding device bottom surface sandbox is vibrated, model and vibration table produce that resonance causes when having solved the airborne dust that adds in the sand process, ram-jolt moves up and down and in the course of time to problems such as damage, jolt ramming degree inequality and the hardness of mould are not enough.Between vibration chassis and table top, the safety margins device has been installed, has been made lift height adjustable, can not damage hoisting system by pressure, even rise or lifting vibration table during maintenance, can the drawing crack hoisting system yet.Under table top, compared with the past, little power of shaking increases with the vibrating motor direct tipping, and power of motor has reduced than originally about 20%, and time of vibration has reduced about 30%, and the sand hardness ratio in the sandbox had improved about 12% originally.
Description of drawings
Fig. 1 is the structural representation of embodiment of the invention V method moulding and disappearance mould jolt ramming device.
The specific embodiment
The structure of moulding of V method and disappearance mould jolt ramming device as shown in Figure 1, comprise the chassis of forming by wheel 5, bearing block 6, track 7, vehicle frame 8 and axletree 10, on described vehicle frame 8, be provided with hoisting system, this connects above hoisting system vibrational system is set, and the travelling mechanism 4 that described vibrational system is moved.
Described hoisting system is an air spring 3, realizes lifting or puts down vibrational system on it by stretching of air spring 3; Described vibrational system involving vibrations motor 1 and vibration table 2, vibrating motor 1 is installed on the vibration table 2, realizes the jolt ramming of top sandbox by vibrating motor 1, and described vibrating motor 1 has 2.
Between described vehicle frame 8 and vibration table 2, the safety margins device is set, this safety margins device is chassis alignment pin 9 and the mutually corresponding with it chassis positioning sleeve 12 that is arranged on the vibration table 2 that is arranged on the vehicle frame 8, and between described vibration table 2 and sandbox, being provided with mutual corresponding positioning element, this positioning element is a mould alignment pin 11.
The course of work of the present invention is:
A, under positioning element guiding, mold flask is placed on the vibration table;
B, vibration table lift, and under the guiding of safety margins device, are close to the sanding device sandbox and add the sand vibration;
C, separate with sanding device, sandbox transports;
D, vibration table are got back to original position, wait for that next mold flask arrives.
Repeat above operating process, cycle operation.
Moulding of above-mentioned V method and disappearance mould jolt ramming device are placed on mold flask on the vibration table, with chassis alignment pin and the chassis positioning sleeve fixed mould that matches, have guaranteed that the location is reliable, the problem of mould move left and right in the time of can not occurring vibrating.When adding sand, inflate to air spring by Compressed Gas, vibration table is lifted be close to the sanding device bottom surface and add sand vibration, form the enclosed type vibrating device that sand and dust do not leak when adding sand, take out the dirt function, so sand and dust can not fly upward.Sanding device withstands sandbox, so mould can not produce vibration.The air spring exhaust falls vibration table after the jolt ramming, by the safety margins device chassis and table top is fixed together, and can not damage air spring by pressure.Can not produce during the chassis operation and shake, and lift height is adjustable, the vibration table of slinging when maintenance exactly can not damage air spring yet.
