Abstract
The invention discloses a wax mould forming method for a shell cover of a mowing machine. The wax mould forming method for the shell cover of the mowing machine is characterized in that mould forming is used, a mould comprises an upper mould body and a lower mould body, and the lower mould body, a liner block and a mould fixed clamping plate are connected through a hexagon socket head cap screw; when the mould bodies are combined, a closed cavity is formed by the upper mould body and the lower mould body, ejector guide bushes and ejector guide pillars are added so that the upward moving directivity and the positional accuracy of a pushing plate, a pushing plate fixing plate and a pushing rod can be guaranteed, and the two ends of the ejector guide pillars are correspondingly connected with the lower mould body and the mould fixed clamping plate in a matched mode. According to the wax mould forming method for the shell cover of the mowing machine, structure is simple and operation is convenient.
Description
Technical field
The present invention relates to a kind of mowing cabinet cover shaping investment pattern method.More particularly to mowing machine part wax-pattern molds manually
Field question.
Background technology
Hot investment casting does casting mold raw material with wax, and modification is flexible, and can recycle, and can greatly save and produce into
This.More widespread practice is：Make the mould of required blank, then the method casting wax with casting first, obtain original wax-pattern.
Paint resistant to elevated temperatures liquid sand material in wax-pattern last layer layer.Dry after obtaining enough thickness, then heat, make the wax-pattern of inside
Melt away, obtain the die cavity consistent with required blank.Shell is removed after solidification, just can obtain by casting molten iron in die cavity again
Obtain high-precision finished product.
Mowing cabinet cover is thin-walled type component, and its profile is more complicated, and there is a macropore upper surface, in part arc table
One opening is also had on face, each right-angle side has done fillet process, and overall processing required precision is higher.And casing surroundings are high
Degree size is big, makes to be not easy in shaping investment pattern to make it separate with mold, and easily produces interference it is contemplated that mowing
The economy of cabinet cover Wax mold volume block processing and precision, design a kind of mould right and wrong being suitable for thin-wall part shaping investment pattern
Often important.
Content of the invention
The purpose of the present invention is exactly to solve the above problems, and provides a kind of mowing cabinet cover shaping investment pattern method, and it has
There is simple, the easy to operate advantage of structure.
To achieve these goals, the present invention adopts the following technical scheme that：A kind of mowing cabinet cover shaping investment pattern method, profit
With mould molding, it is characterized in that, it includes upper die and lower die, described upper mould is integral-typed punch, lower mould is solid die, under
Mould, cushion block and top clamping plate are linked together by hexagon socket cap head screw, and during matched moulds, upper die and lower die synthesize enclosed type
Chamber, in order to ensure the accuracy of the position of upper and lower mould, realizes positioning by two straight pins, in order to ensure in casting process
In, upper and lower mould makes it separate due to die cavity internal pressure, is clamped by wing nut.
Described cap Wax mold die sinking during, by reality is uniformly distributed by the liftout attachment that five push rods form
Existing, push rod is connected by gap with lower mould, push rod and push pedal, push pedal fixed plate by being connected, in order to ensure push pedal,
Guidance quality and the accuracy of position that push pedal fixed plate and push rod move upwards, increased ejector guide pillar and push pedal guide pillar, wherein
Push pedal guide pillar passes through to be connected with lower mould and top clamping plate up and down respectively.
Described cap Wax mold die sinking process is manual die sinking, and concrete operations are first to open wing nut to make upper and lower mould
Tool separates, and removes mould.Then manual-up lift push pedal, so that push rod is moved upwards, until mowing cabinet cover wax-pattern depart under
Model cavity, takes off wax-pattern, and push pedal resets, and completes working cycles.
Advantages of the present invention：
Present configuration is simple, and easy to operate, purely manual operation solves the shaping of the wax-pattern of mowing cabinet cover part, economical
Property good, and be suitable for the difficult problem of the model casting of thin-wall case class part, and improve operating efficiency.

Specific embodiment：
The invention will be further described with embodiment below in conjunction with the accompanying drawings：
As shown in Figures 1 to 6, a kind of mowing cabinet cover shaping investment pattern method, using mould molding, is characterized in that, it includes
Mould 13 and lower mould 11, described upper mould 13 is integral-typed punch, and lower mould 11 is solid die, lower mould 11, cushion block 4 and top clamping plate
5 are linked together by hexagon socket cap head screw 3, and during matched moulds, upper mould 13 and lower mould 11 synthesize near closed hollow ring, in order to ensure
The accuracy of the position of upper and lower mould, realizes positioning, in order to ensure during casting, upper and lower mould by two straight pins 2
Because die cavity internal pressure makes it separate, clamped by wing nut 1.
Above-mentioned cap Wax mold die sinking during, by reality is uniformly distributed by the liftout attachment that five push rods 9 form
Existing, push rod 9 is connected by gap with lower mould 11, and push rod 9 passes through to be connected with push pedal 6, push pedal fixed plate 7, in order to protect
Guidance quality and the accuracy of position that card push pedal 6, push pedal fixed plate 7 and push rod 9 move upwards, increased ejector guide pillar 8 and push away
Plate guide pillar 10, wherein push pedal guide pillar pass through to be connected with lower mould 11 and top clamping plate 5 about 10 respectively.
Above-mentioned cap Wax mold die sinking process be manual mold, concrete operations be first open wing nut 1 make mould 13,
Lower mould 11 separates, and removes mould 13.Then manual-up lift push pedal 6, so that push rod 9 is moved upwards, until mowing cabinet cover wax
Mould departs from lower mould 11 die cavity, takes off wax-pattern, push pedal 6 resets, completes working cycles.
