Abstract
The utility model discloses a casting box for a bearing cover of a cast diesel engine, which comprises a pattern plate, a sprue, a runner and cast grooves, and is characterized in that the cast grooves are eight at least and symmetrically formed on the pattern plate; the runner is respectively communicated with each cast groove to form a blank holding runner structure; and the sprue is arranged in the center of the pattern plate. The casting box for the bearing cover of the cast diesel engine adopts the blank holding runner to carry out the feeding, thereby not only increasing the yield of the casting process, but also avoiding the phenomena of possible hole shrinkage and looseness which are caused by the contact thermal center generated by a large riser, a riser neck and casts, and improving the quality of the casts; simultaneously, the casting box for the bearing cover of the cast diesel engine can change the parting surface and reduce the projection area of the casts on the parting surface; and one type of the same casting box can produce eight casts, thereby greatly reducing the cost of the casts.
Description
Technical field
The utility model relates to a kind of mould, what be specifically related to is a kind of moulding sandbox of casting the diesel engine bearing cap.
Background technology
Main beating cap is important component part in the diesel engine, and material is QT500-7, requires inside that casting flaws such as shrinkage cavity, shrinkage porosite, pore can not be arranged, and casting structure as shown in Figure 1.
Cast bearing lid sandbox generally adopts horizontal parting now, and a mould four types adopt big rising head to concentrate the mode (as shown in Figure 2) of feeding; This bearing cap comprises template 1, sprue 2, cross gate 3, foundry goods groove 5 and rising head and riser neck 4, and foundry goods groove 5 is symmetricly set on the template 1, and rising head and riser neck 4 are arranged on the center of template 1, and cross gate 3 is arranged on the template marginal portion.By the bearing cap of this structure, because diesel engine one cylinder is in great demand with regard to the bearing cap of wanting.But adopt this mode to produce, efficient is lower, and the production work amount is bigger; And owing to be to adopt big rising head and riser feeding, the thermal center of generation is also bigger, and yield rate is lower, and tends to produce the defective of shrinkage porosite in foundry goods inside.
The utility model content
At the deficiency that exists on the prior art, the utility model purpose is to be to provide a kind of phenomenon that thermal center may produce shrinkage cavity and shrinkage porosite that contacts of avoiding concentrating big rising head and riser neck and foundry goods generation, improved the diesel engine bearing cap sandbox of casting quality, effectively enhance productivity, reduced production cost.
To achieve these goals, the utility model is to realize by the following technical solutions:
A kind of casting diesel engine bearing cap sandbox comprises template, sprue, cross gate and foundry goods groove, it is characterized in that described foundry goods groove is provided with 8 at least, and is symmetricly set on the template; Described cross gate is connected with each foundry goods groove respectively, constitutes flanging cross gate structure; Described sprue is arranged on the center of template.
Above-mentioned a kind of casting diesel engine bearing cap sandbox, wherein, described foundry goods groove has changed the die joint of template for being horizontally arranged on the template, has reduced the projected area of foundry goods at die joint.
The utility model adopts the flanging cross gate to carry out feeding, not only improved the casting technique yield rate, but also avoided concentrating the phenomenon that contacts issuable shrinkage cavity of thermal center and shrinkage porosite of big rising head and riser neck and foundry goods generation, improved the quality of foundry goods, simultaneously, changed die joint, reduced the projected area of foundry goods at die joint, same sandbox one type can be produced 8 foundry goods, thus the casting cost that reduces widely.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the structural representation of existing cast bearing lid sandbox.
Fig. 2 is a structural representation of the present utility model.
Fig. 3 is the product schematic diagram of this example.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
Embodiment:
Referring to Fig. 2, the diesel engine bearing cap sandbox of present embodiment, comprise template 10, sprue 12, cross gate 11 and foundry goods groove 13, on template 10, be arranged with 8 foundry goods grooves 13, each foundry goods groove 13 is and is horizontally arranged on the template 10, changed the die joint of template 10, reduced the projected area of foundry goods at die joint.Walk crosswise described foundry goods groove 13 and be provided with 8 at least, same sandbox one type can be produced 8 foundry goods, has improved production efficiency.
Described cross gate 11 is connected with each foundry goods groove 13 respectively, all with the 13 flanging settings of foundry goods groove, promptly constitutes the flanging cross gate structure of sandbox; Made sprue 12 at the center of template, this sprue 12 is connected with cross gate 11, is convenient to the casting of foundry goods.
The utility model is in when casting, and the staff can be poured in each foundry goods groove by sprue 12 and cross gate 11, wait to be cooled after, the bearing cap (as shown in Figure 3) that can to generate the required foundry goods that has be diesel engine.The utility model has been removed big rising head and riser neck, has avoided concentrating big rising head and riser neck and the phenomenon that contacts issuable shrinkage cavity of thermal center and shrinkage porosite that foundry goods produces, and has improved the quality of foundry goods.
Base gives above-mentioned, the utility model adopts the flanging cross gate to carry out feeding, adopt as this pouring type, improved the quality of casting technique product and foundry goods, simultaneously, changed die joint, reduced the projected area of foundry goods at die joint, same sandbox one type can be produced 8 foundry goods, thus the casting cost that reduces widely.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (2)
