Description
Technical field
The present invention relates to Metallic Casting Die & Mold technical fields, and in particular to a kind of for processing the mold of gate valve body.
Background technique
Valve is the control unit in fluid delivery system, has cut-off, adjusting, water conservancy diversion, prevents adverse current, pressure stabilizing, shunting
Or the functions such as overflow pressure relief.Valve body is a main parts size in valve, is in the fluid system, for controlling the side of fluid
To, the device of pressure, flow.Gate valve generally includes valve body and flashboard, and wherein flashboard is the opening and closing element of gate valve, the movement side of flashboard
To perpendicular with flow direction, as a main component of gate valve, valve body accommodating chamber compatible with valve plate is mostly directly casting
It makes.And previous valve body positions the type core in mold in mold production process manually, being easy positioning is not allowed,
Then using being screwed manually, hand-operated core pulling is carried out after valve body machine-shaping, wherein core package includes valve plate channel-style core
With medium channel type core, valve plate channel-style core includes the first baroclinic block, the second baroclinic block and struts block, the first baroclinic block, second
Protrusion is provided on baroclinic block, after valve body molding, valve inner has recess portion corresponding with protrusion, and details are as shown in attached drawing 11
Sectional view, so to valve plate channel-style core carry out core pulling when, the first baroclinic block, the second baroclinic block protrusion can be by the recessed of valve body
Portion is blocked, and is needed first to be fully drawn out and is strutted block, and the first baroclinic block and the second baroclinic block could be taken out, and Forming Quality is manually operated
It is low, process is cumbersome, and production efficiency is lower.
Summary of the invention
In conclusion in order to overcome the deficiencies of the prior art, the present invention provides that a kind of Forming Quality is high, easy to operate and efficiency
The high mold for being used to process gate valve body.
To achieve the above object, the present invention provides the following technical scheme that it is a kind of for processing the mold of gate valve body, it wraps
Top mold holder, lower mold holder, type core, core-pulling device are included, wherein core package includes valve plate channel-style core and medium channel type core, valve plate channel
Core package includes the first baroclinic block, the second baroclinic block and struts block, and first baroclinic block, second baroclinic block are respectively arranged at
It is described to strut block two sides, it is described to strut that block corresponds to first baroclinic block, the two sides of second baroclinic block are respectively present from tail
It holds to the intilted inclined-plane in top, it is described to strut that be provided between block and first baroclinic block, second baroclinic block
First baroclinic block, second baroclinic block edge is set to strut the guidance set that block inclined-plane is gradually drawn close to centre.
By using above-mentioned technical proposal, when detach strut block when, be respectively present from tail end to top due to strutting block two sides
Intilted inclined-plane is held, the first baroclinic block, the second baroclinic block, which are respectively arranged at, struts block two sides, and the first baroclinic block, second are tiltedly
It briquetting and struts and is provided with guidance set between block, so the first baroclinic block, second are tiltedly when strutting block and detaching toward core pulling direction
Briquetting can gradually be drawn close to centre along strutting block inclined-plane, thus make the first baroclinic block, the protrusion of the second baroclinic block progressively disengage with
The recess portion of formed valve body, is no longer stuck, i.e., twitch struts block can drive the first baroclinic block, the second baroclinic block to be detached from by card simultaneously
State firmly, simplifies operating process, improves work efficiency.
The present invention is further arranged: the guidance set includes guide groove and guide pad compatible with the guide groove,
The guide groove is respectively arranged at the two sides for strutting relatively described first baroclinic block of block, second baroclinic block, described to lead
First baroclinic block, second the baroclinic block relatively described side for strutting block respectively, the guide pad edge are set to block
The guide groove is mobile.
By using above-mentioned technical proposal, pass through guide pad and the guiding that struts block of the first baroclinic block, the second baroclinic block
Cooperation between slot improves the kinematic accuracy of the first baroclinic block and the second baroclinic block, while can prevent the first baroclinic block, second
Baroclinic block and guide groove are detached from, and keep structure more stable.
The present invention is further arranged: the block that struts includes core pulling portion, and the core section of smoking is that top is narrow, tail end is wide
Trapezoidal, first baroclinic block, second baroclinic block are respectively arranged at core pulling portion two sides, and the guide groove is respectively set
In the trapezoid cross section stringcourse direction in the core pulling portion, the guide groove is parallel with the trapezoid cross section stringcourse in the core pulling portion, institute
Stating guide groove, groove width is equal everywhere.
By using above-mentioned technical proposal, strutting block includes core pulling portion, and the first baroclinic block, the second baroclinic block are respectively arranged at
Core pulling portion two sides, taking out core section, to be that top is narrow, tail end is wide trapezoidal, and guide groove is respectively arranged at trapezoidal section of core pulling portion two sides
Face stringcourse direction, so the first baroclinic block, the second baroclinic block can be along guide grooves gradually when often core pulling direction detaches in core pulling portion
It is drawn close to centre, guide groove is parallel with the trapezoid cross section stringcourse in core pulling portion, so that the first baroclinic block, the second baroclinic block are along guiding
Slot is drawn close more smooth, and groove width is equal everywhere for guide groove, guide pad along guide groove slide it is more stable, be not easily disconnected from.
The present invention is further arranged: the core-pulling device includes medium channel core-pulling mechanism and valve plate channel core-pulling mechanism,
Valve plate channel core-pulling mechanism includes valve plate channel core pulling component and driving assembly, and core pulling component in valve plate channel includes first solid
