Abstract
The utility model relates to a kind of molds for the casting of thin plate class casting bilayer, including die ontology, die ontology is divided into upper impression and lower impressions, sand core is provided between upper impression and lower impressions, several riser are symmetrically arranged with around the edge of upper impression and lower impressions, riser includes by upper riser neck and lower riser neck, and upper riser neck is connected with upper impression, and lower riser neck is connected with lower impressions.The utility model structure is simple, it is compact to design, it is easy to use, one mold can not only produce two casting simultaneously and improve production efficiency, the riser that edge is uniformly arranged can carry out certain constraint and traction action to casting, casting can be reduced in process of setting because of the buckling deformation tendency that each position cooling velocity unevenly generates, improve the qualification rate of product.
Description
Technical field
The utility model relates to a kind of molds for the casting of thin plate class casting bilayer, belong to casting technology field.
Background technique
The production of thin plate class casting is always the more difficult product of Foundry Production, is mainly reflected in following 2 aspects:
(1) because its area is big, can be arranged in template in the case that casting automatic moulding production line sandbox size is certain zero
Part is few, and production efficiency is low, product yield is low；
(2) since the influence of boss, muscle and casting system on casting leads to the cooling speed in each position of casting in process of setting
Degree is uneven, and buckling deformation, the casting buckling deformation of general 600 × 300 × 25mm are generated in the case where no external force constraint
It is even more that amount can reach 1mm.
Summary of the invention
Purpose of the utility model is to solve the above problems that thin plate class casting occurs in casting process, provide
A kind of structure is simple, the mold for the casting of thin plate class casting bilayer compact to design.
The utility model adopts the following technical solution: a kind of mold for the casting of thin plate class casting bilayer, including mold
Ontology, the die ontology are divided into upper impression and lower impressions, are provided with sand core between the upper impression and lower impressions, surround upper impression
Be symmetrically arranged with several riser with the edge of lower impressions, the riser includes upper riser neck and lower riser neck, it is described on emit
Mouth neck is connected with upper impression, and the lower riser neck is connected with lower impressions.
Further, the sand core with a thickness of 15mm.
Further, the die ontology is used to cast the thin plate class cast pieces of spheroidal of 600 × 300 × 25mm.
The utility model structure is simple, compact to design, easy to use, and a mold can not only produce two casting simultaneously
Production efficiency is improved, the riser that edge is uniformly arranged can carry out certain constraint and traction action to casting, can reduce
Casting, because of the buckling deformation tendency that each position cooling velocity unevenly generates, improves the qualification rate of product in process of setting.
Detailed description of the invention
Fig. 1 is the overlooking structure diagram of the utility model.
Fig. 2 is the cross-sectional view of the riser of the utility model.
Appended drawing reference: riser 1, upper riser neck 1-1, lower riser neck 1-2, sand core 2, upper impression 3, lower impressions 4.
Specific embodiment
Below in conjunction with attached drawing, the utility model will be further described.
As Figure 1-Figure 2, a kind of mold for the casting of thin plate class casting bilayer, including die ontology, die ontology
It is divided into upper impression 3 and lower impressions 4, sand core 2 is provided between upper impression 3 and lower impressions 4, around the edge of upper impression 3 and lower impressions 4
It is symmetrically arranged with several riser 1, riser 1 includes upper riser neck 1-1 and lower riser neck 1-2, upper riser neck 1-1 and upper impression
3 are connected, and lower riser neck 1-2 is connected with lower impressions 4, sand core 2 with a thickness of 15mm, die ontology is for casting 600 × 300
The thin plate class cast pieces of spheroidal of × 25mm.
The preparation method of thin plate class casting:
(1) casting form is manufactured, the core print for placing intermediate sand core is designed in apperance bottom；
(2) two apperances are superposed in the same template, are respectively formed apperance；
(3) several riser are symmetrically set in the edge of two apperances, each riser is respectively arranged with riser
Neck and lower riser neck, upper riser neck are connected in apperance, and the lower riser neck is connected in lower apperance；
(4) intermediate core mold is manufactured, intermediate sand core is prepared；
(5) the upper apperance of superposition and lower apperance are produced to the upper impression and lower impressions of the molten iron that is used to cast on moulding machine；
(6) intermediate sand core is placed in lower impressions, then vertically closes upper impression in lower impressions；
(7) it is cast respectively into upper impression and lower impressions by each riser and is used to prepare the molten iron of Cast Thin Sheet；
(8) casting is natural cooling in sand mold after casting, and knockout obtains thin plate class casting after cooling time is greater than 120min；
(9) it unpacks and takes out casting and clean out.
Claims (3)
