Abstract
A power transmission mechanism for a moulding sand compaction device comprises a support plate; the support plate is provided with connecting holes; the support plate is fixed a gravity plate of the compaction device by bolts; a bracket is arranged on the upper end of the support plate; the bracket is provided with a concave wheel; a cam is arranged on one side of the concave wheel; the cam is connected with a gear box; a shaft hole is arranged in the middle of the cam; an output shaft of the gear box is connected to the shaft hole of the cam; the inner wall of the shaft hole is provided with a keyway; and concave wheel moving up and down during working cannot touch the cam, and in other words, the center horizontal distance between the concave wheel and the cam is greater than the total sum of the maximum radius of the concave wheel and radius of an intermediate shaft aperture of the cam. The invention has the advantages of simple structure and novel design, cooperation of the cam and the concave wheel drives the gravity plate to move up and down, so as to achieve the purpose of moulding sand compaction, reduce the labor intensity of workers, and improve the production efficiency of the moulding.
Description
Technical field
The present invention relates to casting technology field, be specifically related to a kind of sand compaction device power drive mechanism.
Background technology
Casting is cast to by liquid metals in the casting cavity that adapts with part shape, after its cooled and solidified, to obtain the method for part or blank.Mostly be by casting material matter and be solid-state originally but be heated to liquid metal (example: copper, iron, aluminium, tin, lead etc.).The casting mold of conventional cast has molding sand, resin, waterglass etc.The casting mold of Special Processes of Metal Castings has: model casting, lost foam casting, permanent mold casting etc.In ordinary sand casting, model is put in sandbox, then fill sandbox with molding sand.Consolidation to be carried out to sandbox after having filled, so just model can be taken out with to be cast.The mode of consolidation has a variety of, have mechanical consolidation and artificial consolidation point.For the foundry production line of small lot, be mostly manually by simple ram-jolt instrument and tamping tool to realize molding sand consolidation, the mode of artificial consolidation then increases the labour intensity of moulding workman, also production efficiency is reduced to a certain extent, if sandbox has reinforcement, the efficiency of artificial consolidation can be lower.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of labour intensity reducing workman, improves the sand compaction device power drive mechanism of moulding production efficiency.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of sand compaction device power drive mechanism, comprise a support baseboard, described support baseboard is provided with connecting hole, by bolt, support baseboard is fixed on the gravity plate of compaction apparatus, described support baseboard upper end is provided with a bracket, described bracket is provided with spill wheel, described spill wheel side is provided with cam, described cam is connected with gearbox, axis hole is provided with in the middle of cam, the output shaft of described gearbox is connected in the axis hole of cam, described shaft hole inner wall is provided with keyway, the spill wheel moved up and down during work can not touch cam, in other words, spill wheel is greater than with the central horizontal distance of cam the radius sum that spill takes turns maximum radius and cam intermediate shaft hole, i.e. L>r+R.
Described cam two ends are provided with dials stopper, is symmetrical set, and engages for the groove in the middle of same spill wheel.
The invention has the beneficial effects as follows: structure of the present invention is simple, novel in design, drive gravity plate to move up and down by coordinating of take turns of cam and spill, reach the object of compacting molding sand, the labour intensity of reduction workman, the production efficiency of raising moulding.

Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
See Fig. 1-5:
A kind of sand compaction device power drive mechanism, comprise a support baseboard 1, described support baseboard 1 is provided with connecting hole 2, by bolt 3, support baseboard 1 is fixed on the gravity plate 4 of compaction apparatus, described support baseboard 1 upper end is provided with a bracket 5, described bracket 5 is provided with spill wheel 6, described spill is taken turns 6 sides and is provided with cam 7, described cam 7 is connected with gearbox 8, axis hole 9 is provided with in the middle of cam 7, the output shaft of described gearbox 8 is connected in the axis hole 9 of cam 7, described axis hole 9 inwall is provided with keyway, the spill wheel 6 moved up and down during work can not touch cam 7, in other words, spill wheel 6 is greater than with the central horizontal distance L of cam 7 the radius R sum that spill takes turns 6 maximum radius r and cam 7 intermediate shaft hole 9, i.e. L>r+R.Cam 7 two ends are provided with dials stopper 10, is symmetrical set, and engages for the groove in the middle of same spill wheel 6.
The method of work of compaction apparatus: populated molding sand treated that consolidation sandbox is put into the below of gravity plate 4, cam 7 rotates under the drive of gearbox 8, the cam 7 of rotation by with spill take turns 6 engaging, bracket 5 is moved upward, and gravity plate 4 also just moves upward.When cam 7 and spill take turns 6 be separated time, now gravity plate 4 arrives highest point, both be separated after, gravity plate 4 free-falling, pounds in the sandbox of below, and the molding sand in sandbox obtains compacting.Along with the not stall of cam 7 is moved, gravity plate more than 4 pressure pounds sandbox, and the molding sand in sandbox obtains good consolidation, when after sand compaction, turns off gearbox 8, then takes out sandbox.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
