Abstract
The invention provides an improved side die limiting block which comprises a cover body (1) and a pillar body (4). The lower portion of the cover body (1) is connected with the pillar body (4). The lower side of the cover body (1) is wider than the pillar body (4), and a step-shaped structure is formed. The upper surface of the cover body (1) is an oblique upper surface. The pillar body (4) comprises a blind hole (3). When the side die limiting block is arranged to be installed on a die bottom plate, the pillar body (4) is inserted in a hole in the die bottom plate, and the hole of the die bottom plate is completely covered with the cover body (1). The improved side die limiting block has the beneficial effects that when the limiting block is installed on the die bottom plate, hole, gap and acute angle space is not formed in the surface of the die bottom plate, only an obtuse angle contact face is formed, and the phenomenon of aluminum sticking is reduced. If even little aluminum is stuck, the aluminum can be removed from the surface very easily.
Description
Technical field
The present invention relates to a kind of novel side mould limited block, it is used suitable for low pressure casting die.
Background technology
During low pressure casting die of aluminum alloy hub use, limited block is mounted in the important component on upper-mould top
One of, mainly being used in the mould of top pressure bottom structure, Main Function is to prevent from being opened outside the mould upper end of side producing gap so as to cause
Blank overlap, opposite side mould plays the role of one and pushes and limit.For the ease of installation and removal, the limited block for using at present is installed
It is complete to there is certain interval with top board, and the gap can often occur the problem of viscous aluminium and drop in process of production.Due to system
Make the reasons such as precision, die deformation, production technology, it is impossible to avoid limited block surrounding gap location from forming viscous aluminium, and machine enters under mould
When being safeguarded after row, aluminium also very difficult cleaning is glued herein.In mould sandblasting procedures, also had in limited block surrounding gap residual
Remaining corundum sand is present, and in machine production process on mould, with the die sinking matched moulds of mould, residual corundum sand can fall into type
Chamber, causes blank waste product.
The content of the invention
The present invention is improved by by current limited block and upper-mould top, by the limited block keyway size of upper-mould top
It is optimized, overall dimensions diminish after optimization, and be not connected with top template stop portion.Simultaneously by the structure and chi of limited block
Very little to be also carried out corresponding modification, the limited block after optimization is wide at the top and narrow at the bottom, and the bottom surface of limited block is completely by original gap after installation
Covered, and inclined-plane will have been made with backform adjacent surface, even if there is viscous aluminium, cleared up also more convenient.It is very close to each other same after installation
When it also avoid the risk of the drop toward in die cavity.
In one aspect of the invention, there is provided a kind of improved side mould limited block, described side mould limited block includes lid
Body (1) and cylinder (4)；Described lid (1) lower section connection cylinder (4)；The downside of described lid (1) is more wider than cylinder (4),
Form step-like structure；The upper surface of described lid (1) is inclined upper surface (2)；Include inside described cylinder (4) blind
Hole (3)；When described side mould limited block is set to be installed to die bottom plate, cylinder (4) be inserted into the hole of die bottom plate and
Lid (1) is completely covered the hole of die bottom plate.
Angle is fillet between currently preferred aspect, the described upper surface of lid (1) and the side of lid (1)
Obtuse angle, the angle between the side of described lid (1) and die bottom plate is obtuse angle.
There is 2-4 blind hole inside currently preferred aspect, described cylinder (4).
In other aspects of the present invention, the casting mould comprising previously described side mould limited block, its feature are additionally provided
It is that described casting mould has base plate, lower mould, Bian Mo and upper mould；Described lower mould is fixed on base plate, and base plate surrounding sets
Hole is equipped with, previously described side mould limited block is provided with hole；While mould by while mould limited block be installed on base plate；Upper mould is installed
To the top of side mould.
In currently preferred aspect, described side mould limited block is installed between adjacent die bottom plate column.
The advantage of limited block of the invention is to be installed to when on die bottom plate, and hole, seam are not formed on die bottom plate surface
The space of gap and acute angle, only forms the contact surface at obtuse angle, so as to reduce the phenomenon of viscous aluminium.Even there is fraction of viscous aluminium,
Also it is easy to be removed from surface.
Brief description of the drawings
Hereinafter, embodiment of the present invention is described in detail with reference to accompanying drawing, wherein：
Fig. 1：The profile of the side mould limited block of embodiments of the invention 1；
Fig. 2：The upward view of the side mould limited block of embodiments of the invention 1；
Fig. 3：The scheme of installation of the side mould limited block of embodiments of the invention 1.
In figure：1- lids, 2- upper surfaces, 3- blind holes, 4- cylinders, the improved limited block set locations of 31-, 32- are traditional
Limited block set location.
Specific embodiment
Embodiment 1
The present invention is described further below in conjunction with the accompanying drawings.
Improved side mould limited block is present embodiments provided, described side mould limited block includes lid (1) and cylinder (4)；
Described lid (1) lower section connection cylinder (4)；The downside of described lid (1) is more wider than cylinder (4), forms step-like structure；
The upper surface of described lid (1) is inclined upper surface；Include blind hole (3) inside described cylinder (4)；Described side mould limit
When position block is set to be installed to die bottom plate, cylinder (4) is inserted into the hole of die bottom plate and lid (1) is completely covered mould
The hole of base plate.Angle is fillet obtuse angle between the upper surface of described lid (1) and the side of lid (1), described lid (1)
Side and die bottom plate between angle be obtuse angle.There are 4 blind holes inside described cylinder (4).
The upper-mould top limited block groove that uses is arranged on the groove part at present, and surrounding has a gap after installation, and with top
Plate stop portion is connected.As shown in Figure 1, overall dimensions are optimized groove after improvement, and keep apart with top board stop portion.
Current limited block installs four weekly assemblies and there is gap, and the gap easily occurs viscous aluminium in process of production, and is difficult to clean up.
Easily there is residual corundum sand in mould sandblasting procedures, that falls into die cavity in process of production, causes blank waste product.Improve
Limited block afterwards is wide at the top and narrow at the bottom, and the bottom surface of limited block is completely covered original gap after installation, therefore is not had with top board
Gap, largely avoids drop and the generation of viscous aluminium.And with backform adjacent beveling, if any it is abnormal occur it is viscous
Aluminium, is also easy to cleaning.
Limited block of the invention and fit system, are not limited to content of the present invention, every according to present invention
Other corrective measures for inspiring and obtaining, each fall within protection scope of the present invention.
