Abstract
The utility model discloses a kind of casting die device of mud core, comprise mud core external mold, described length is two sections that the mud core external mold of 5230mm is divided into equal length, described mud core external mold is made up of separable bed die and backform, in the middle of described bed die and backform, have columned mud core groove, arrange in described mud core groove and arbor is installed.Evenly be provided with the pore of three vertical directions in described backform, described pore runs through backform and is connected with arbor is vertical.This device is easy and simple to handle, effectively can promote mud core and main lubrication road accuracy of gauge, improves service life and the qualification rate of mud core.
Description
Technical field
The utility model relates to a kind of casting die device, is specifically related to a kind of casting die device for main lubrication road mud core.
Background technology
In traditional fuselage foundry goods, requirement mud core casts out the diameter that length runs through whole fuselage is 120mm, the long main oil leab for 5230mm, and require except the two ends of whole main oil leab, middle without larger branched bottom, because main lubricating oil is to oversize cause, in casting process, the often bending situation of oil road, therefore the accuracy of mud core directly determines the accuracy of main oil leab, only export by two ends is impossible accomplish the location of long for 5230mm mud core to fix simultaneously, higher to the requirement of the dimensional accuracy of whole main oil leab, in foundry production, difficulty increases.
Fig. 1 is the utility model patent " a kind of casting die device for main lubrication road mud core " applied for by Anqing Zhongchuan Diesel Engine Co., Ltd. on June 12nd, 2012, the patent No.: 201220274356.0.This utility model comprises mud core external mold 1, and length is two sections that the mud core external mold 1 of 5230mm is divided into equal length.The external mud core groove 2 having semicircle arcuation at the center of mud core external mold 1, the diameter of mud core groove 2 is 120mm, arranges and be provided with arbor 7 in mud core groove 2.Mud core groove 2 left position has the identical round steel groove 3 of three equidistant sizes, and the diameter of this round steel groove 3 is 30 mm.Round steel 6 by round steel groove 3 and the arbor 7 in mud core groove 2 mutual vertical become the right angle of 90 degree.The both sides of mud core external mold 1 are symmetrically arranged with lock tooth 4 respectively, and lock tooth 4 is provided with lock ring 5.
Due in the casting process of mud core, in casting liquid, can air be mixed into unavoidably, therefore produce certain bubble at fluid origin mud core inner and surface, reduce mud core and main oil leab dimensional accuracy, affect service life and the qualification rate of mud core, cause certain economic loss.
Summary of the invention
Technical problem to be solved in the utility model is the casting die device providing a kind of mud core, and it is easy and simple to handle, effectively can promote mud core and main lubrication road accuracy of gauge, improves service life and the qualification rate of mud core.
A casting die device for mud core, comprises mud core external mold, and described length is two sections that the mud core external mold of 5230mm is divided into equal length.Described mud core external mold is made up of separable bed die and backform, columned mud core groove is had in the middle of described bed die and backform, the diameter of described mud core groove is 120mm, arrange in described mud core groove and arbor is installed, evenly be provided with the pore of three vertical directions in described backform, described pore runs through backform and is connected with arbor is vertical.
Described mud core groove side has the identical round steel groove of three equidistant sizes, and the diameter of described round steel groove is 30 mm, and round steel is mutually vertical with the arbor in mud core groove by round steel groove.
The both sides of described bed die and backform are respectively arranged with corresponding lock tooth, and lock tooth is provided with lock ring.
The beneficial effects of the utility model are: due to the setting of pore, in the casting process manufacturing mud core, the bubble being mixed into casting liquid is discharged through pore, effectively eliminates the generation of bubble in mud core, improve service life and the qualification rate of mud core, promote main lubrication road accuracy of gauge further.

Fig. 1 is the structural representation of utility model in background technology;
Fig. 2 is the utility model structural representation;
Fig. 3 is the utility model pore structural representation of being connected vertical with arbor.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As Fig. 2,3, a kind of casting die device of mud core, comprises mud core external mold 1, and length is two sections that the mud core external mold 1 of 5230mm is divided into equal length.Mud core external mold 1 is made up of separable bed die 11 and backform 12, columned mud core groove 2 is had in the middle of bed die 11 and backform 12, the diameter of mud core groove 2 is 120mm, and setting is provided with arbor 3 in mud core groove 2, evenly be provided with the pore 4 of three vertical directions in backform 12, this pore 4 runs through backform 12 and is connected with arbor 3 is vertical.
Mud core groove 2 side has the identical round steel groove 5 of three equidistant sizes, the diameter of round steel groove 5 is 30 mm, and round steel 6 is mutually vertical with the arbor 3 in mud core groove 2 by round steel groove 5, be respectively arranged with corresponding lock tooth 7 in the both sides of bed die 11 and backform 12, lock tooth 7 is provided with lock ring 8.
The both sides of described bed die and backform are symmetrically arranged with lock tooth respectively, and described lock tooth is provided with lock ring.More than show and describe general 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; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
