Abstract
The invention relates to a casting model, which is characterized in that: the bottom of the casting model, which is in contact with a model bottom plate, is provided with an embedded lug boss, and the lug boss is embedded into the model bottom plate; the lug boss and the upper plane of the model bottom plate form a parting surface, and the corner of the parting surface on the lug boss is provided with an inclined surface with a slope of 60 degrees; and the length of the bottom side of the inclined surface is 1.5mm, and a joint of the inclined surface and the parting surface is provided with an R1.5 fillet. Under the premise of unaffecting the size and the configuration of a casting, the model and the model bottom plate are designed into an embedded mode; and the corner of the parting surface is provided with the inclined surface with the slope of 60 degrees, and the inclined surface is a manually controllable large-slope flash. The structure is simple, the use is convenient, and sand burning, sharp corner and local tire falling phenomena are improved. The appearance quality of castings is improved, the fins, flashes and burrs of the castings are obviously reduced, the grinding amount can be reduced by over 80%, the production efficiency is increased by about 25%, the labor intensity of workers is greatly reduced, and the casting model is especially suitable for mass production on the crankshaft casting molding line.
Description
Technical field
The present invention relates to a kind of casting technique frock, specifically a kind of casting pattern.
Background technology
All Foundry Works are producing some out-of-shapes both at home and abroad, and the foundry goods that core is more is easy to generate casting flaw, make troubles for the processing of foundry goods.The classifying method of casting pattern is very crucial to the quantity of stripping operation, core.Traditional model classifying method is along center line, adopts the plane somatotype, and integral body is split, and directly model is separated, and keeps the foundry goods profile, and model is installed on the template.Generally will divide mould (type) face to be selected in place, foundry goods maximum cross-section.Like Fig. 3, shown in Figure 4.Fig. 3 is that the prior art model is installed in the sketch map on the template.Fig. 4 is a prior art sand mold sketch map.The die joint place has scab, wedge angle and part to fall the tire phenomenon in the prior art; Foundry goods has obvious fash, overlap, burr.Workman's labour intensity height of polishing, workload is big.
Summary of the invention
Technical problem to be solved by this invention is in order to overcome the deficiency of above-mentioned prior art, to provide a kind of simple in structure, easy to use, can simplify casting technique, alleviate labor strength, the casting pattern with the visual quality of casting of enhancing productivity.
The present invention solve the problems of the technologies described above employing technical scheme be: a kind of casting pattern; It is characterized in that: its bottom that contacts with baffle plate is provided with an embedded boss; This boss embeds baffle plate; Become die joint with planar shaped on the baffle plate, the die joint edge is provided with the inclined-plane that a gradient is 60 degree on the boss, and the base length on inclined-plane is 1.5mm.
Inclined-plane according to the invention and die joint connection are provided with the knuckle of R1.5.Like this, be convenient to the processing of model, guarantee the integrality of model structure, thereby guarantee the integrality of sand mold; The formation of model scab and wedge angle close-in the time of can eliminating casting.
The boss embedded part degree of depth according to the invention is 5-15mm.That is to say and surpass master mould root 5-15mm; Surpass R1.5 knuckle root 3-12mm in other words.Like this, both can guarantee the processing integrality of model die joint place fillet, and be convenient to pre-determined bit again and install.
The present invention is under the prerequisite that does not influence casting dimension and contour structures, and model and baffle plate are designed to inserted; The die joint edge is provided with the inclined-plane that a gradient is 60 degree, and the base length on inclined-plane is 1.5mm.This inclined-plane is the artificial controlled overlap of big gradient.Against existing technologies, the present invention is simple in structure, and is easy to use, and the scab of die joint place, wedge angle and part are fallen the tire phenomenon and improved.Because artificial overlap structure is less, does not almost have in the actual production, the visual quality of casting is improved; The fash of foundry goods, overlap, burr obviously reduce; The polishing amount can reduce more than 80%, and production efficiency improves about 25%, and labor strength significantly reduces; Productivity effect gets a promotion, and is particularly suitable for the crankshaft casting mo(u)lding line and produces in enormous quantities.

The specific embodiment
As can be seen from Figure 1, a kind of casting pattern, the bottom that model 1 contacts with baffle plate 5 is provided with an embedded boss 3, correspondingly is provided with a step on the baffle plate 5.This boss 3 embeds on the step of baffle plate 5, and the last plane of plane and baffle plate forms die joint 4 jointly on the boss 3, and die joint 4 edges are provided with the inclined-plane 2 that a gradient is 60 degree on the boss 3, and the base length on inclined-plane 2 is 1.5mm.
Inclined-plane 2 according to the invention and die joint 4 connections are provided with the knuckle of R1.5.Like this, be convenient to the processing of model, guarantee the integrality of model structure, thereby guarantee the integrality of sand mold; The formation of model scab and wedge angle close-in the time of can eliminating casting.
The boss 3 embedded part degree of depth according to the invention are 5-15mm.That is to say to surpass master mould root 5-15mm, surpass R1.5 knuckle root 3-12mm in other words.With reference to Fig. 1, shown in Figure 3.Like this, both can guarantee the processing integrality of model die joint place fillet, and be convenient to pre-determined bit again and install.
Fig. 4 is a prior art sand mold sketch map.Outside model 1, in mo(u)ld top half sandbox 6 and the mo(u)ld bottom half sandbox 8, fill molding sand 7, between the last drag box die joint 4.Fig. 2 is the sand mold sketch map that the present invention forms, and it is on the structure of existing sand mold, and the edge of die joint 4 forms inclined-plane 2.When mo(u)ld top half sandbox 6 and 8 mould assembling of mo(u)ld bottom half sandbox; Sand mold die joint place (die cavity and die joint junction) uses the inclined-plane 2 of big gradient structure (artificial overlap setting), when preventing molding, and the local scab of model die joint; Make sand mold more complete like this, reduce overlap, burr.
The present invention is under the prerequisite that does not influence casting dimension and contour structures, and upper and lower model is designed to inserted with corresponding baffle plate; The die joint edge is provided with the inclined-plane that a gradient is 60 degree, and the base length on inclined-plane 2 is 1.5mm.This inclined-plane is the artificial controlled overlap of big gradient, and the scab of die joint place, wedge angle and part are fallen the tire phenomenon and improved.Because artificial overlap structure is less, does not almost have in the actual production, the visual quality of casting is improved; The fash of foundry goods, overlap, burr obviously reduce; The polishing amount can reduce more than 80%, and production efficiency improves about 25%, and labor strength significantly reduces; Productivity effect gets a promotion, and is particularly suitable for the crankshaft casting mo(u)lding line and produces in enormous quantities.
