Abstract
The invention discloses a kind of milling machine cover board casting moulds, including epicoele and cavity of resorption, epicoele is provided with the boss of moulder cover board inner cavity and the loose piece on the anti-mouth side of molding, the plug of moulder cover board circular hole is provided on cavity of resorption, pouring hole there are six cavity of resorption both sides are arranged symmetrically, epicoele and lower inner cavity surface are provided with the netted striped of bulge-structure.Structure of the invention is novel, convenient and practical, the bulge-structure of cavity inner surface setting can destroy the film layer that casting liquid is formed, so that casting liquid flowing velocity is fast, surface not will produce more oxidation residua, and flowing fast casting liquid, the gas in cavity can be discharged so that cast(ing) surface will not remain increased number of stomata, by the way that pouring hole is arranged on mold cavity of resorption, the casting for facilitating casting improves the quality of casting.
Description
Technical field
The invention belongs to metal cutting process technical fields, and in particular to a kind of milling machine cover board casting mould.
Background technology
The inner space of milling machine cover board includes an inner cavity and a circular hole communicated with inner cavity, existing casting technique
In, milling machine cover board shape is molded by upper die and lower die, and inner cavity is molded by loam core.Since the inner cavity sides Fan Kou stop, cannot shake out,
So needing to merotomize loam core, and anti-mouth rim portion is molded using loose piece.
It is making and is being also easy to produce error in underlying loam core operating process, causing casting section thickness uneven, dimensional discrepancy occur.Separately
Outside, loam core need to pre-set outlet passageway in coremaking, and block fire to outlet point when mould assembling, and external casting liquid into
After entering in cavity, since the pressure in cavity is smaller, the flow velocity for casting liquid is slower, casts the surface of liquid and can form one layer rich
The film of power forms obstacle, generates excessive oxidation residua, more gas is remained on casting in this way, its flow velocity can be made slower
Hole, this operation sequence and difficulty for increase castings production increase the rejection rate of casting.
Invention content
In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is that providing a kind of milling machine cover board
Casting mould.
The present invention uses following technical scheme：
A kind of milling machine cover board casting mould, is made of epicoele and cavity of resorption, and milling machine cover board is arranged between epicoele and cavity of resorption, on
Intracavitary is provided with the boss for moulder cover board inner cavity and the loose piece on the anti-mouth side of molding, lower intracavitary are provided with plug, core
Stick is used for the circular hole of moulder cover board, and the both sides of cavity of resorption are symmetrical arranged that there are six pouring holes.
Specifically, the inner surface of epicoele and cavity of resorption is both provided with netted striped, netted striped is bulge-structure.
Specifically, the surface of boss is provided with netted striped, netted striped is bulge-structure.
Specifically, being respectively arranged with several gas vents on epicoele and cavity of resorption.
Specifically, plug is enclosed with heat-resisting material set using a joint steel pipe as barred body, in the outer wall of joint steel pipe.
Compared with prior art, the present invention at least has the advantages that：
Structure of the invention is novel, convenient and practical, and the bulge-structure of cavity inner surface setting can destroy what casting liquid was formed
Film layer, so that casting liquid flowing velocity is fast, surface not will produce more oxidation residua, and flow fast casting liquid
Gas in cavity can be discharged so that cast(ing) surface will not remain increased number of stomata, by the way that pouring hole is arranged on mold cavity of resorption,
The casting for facilitating casting improves the quality of casting.
Below by drawings and examples, technical scheme of the present invention will be described in further detail.
Description of the drawings
Fig. 1 is schematic structural view of the invention.
Wherein：1. epicoele；2. cavity of resorption；3. milling machine cover board；4. boss；5. pouring hole；6. loose piece；7. plug.
Specific implementation mode
In the description of the present invention, it is to be understood that, term "center", " longitudinal direction ", " transverse direction ", "upper", "lower", " perpendicular
Directly ", the orientation or positional relationship of the instructions such as "horizontal", "inner", "outside", " side ", " one end ", " one side " is based on shown in attached drawing
Orientation or positional relationship, be merely for convenience of description of the present invention and simplification of the description, do not indicate or imply the indicated device
Or element must have a particular orientation, with specific azimuth configuration and operation, therefore be not considered as limiting the invention.
In addition, in the description of the present invention, unless otherwise indicated, the meaning of " plurality " is two or more.
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " installation ", " phase
Even ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or be integrally connected；It can
Can also be electrical connection to be mechanical connection；It can be directly connected, can also indirectly connected through an intermediary, Ke Yishi
Connection inside two elements.For the ordinary skill in the art, above-mentioned term can be understood at this with concrete condition
Concrete meaning in invention.
Referring to Fig. 1, a kind of milling machine cover board casting mould of the present invention, including epicoele 1 and cavity of resorption 2, epicoele 1 are provided with molding
The boss 4 of 3 inner cavity of milling machine cover board and the loose piece 6 on molding anti-mouth side are provided with the core of 3 circular hole of moulder cover board on cavity of resorption 2
Stick 7, for plug 7 using a joint steel pipe as barred body, joint steel pipe outer wall is enclosed with heat-resisting material set, and 2 both sides of cavity of resorption are symmetrically set
It sets there are six pouring hole 5, in casting process, the pressure in cavity is smaller, and casts liquid in flow process, surface shape
At one layer of film layer rich in surface tension, so that flowing velocity of the casting liquid in the cavity of mold is slower, in order to
Casting liquid is destroyed during flowing, the tensioned film layer of band that surface is formed, epicoele 1 and 2 inner surface of cavity of resorption and convex
4 surface of platform is both provided with the netted striped of bulge-structure.It is respectively arranged with gas vent on the epicoele 1 and cavity of resorption 2, convenient for more preferable
Exhaust gas is discharged in ground, improves castability.
The above content is merely illustrative of the invention's technical idea, and protection scope of the present invention cannot be limited with this, every to press
According to technological thought proposed by the present invention, any change done on the basis of technical solution each falls within claims of the present invention
Protection domain within.
