Abstract
The utility model relates to a preceding brake disc casting die cavity structure, including the cope match-plate pattern body, the vertical columnar mould of watering that is provided with in cope match-plate pattern body center, this water mould lower extreme has set firmly square cope match-plate pattern, this body upper surface of cope match-plate pattern is equipped with annular hot water way mould towards the undercut, and this hot water way mould ring is established at cope match-plate pattern periphery side, the upper surface equipartition of hot water way mould periphery department cope match-plate pattern body has a plurality of mouthfuls of emitting, and this preceding brake disc casting die cavity structure is simple reasonable, will have originally long hot water way to reduce for cyclic annular, can improve the pressure and the velocity of flow that the molten metal got into the die cavity like this for each section of preceding brake disc foundry goods fills the molding time.
Description
Technical Field
The utility model relates to a preceding brake disc casting die cavity structure.
Background
The production of automobile brake discs has become a post industry, ranging from out-dated manual production to mechanization, so that the enterprise ratio of automated production is 7: 2: 1. However, the machining quality of the front brake disc produced by the existing one-box one-mould combined mould is unstable, the flow rate of molten metal entering the cavity is slow due to long soup channels in the existing cavity, so that the mould filling time of each part of the front brake disc casting is not uniform, and the production quality of the front brake disc casting is influenced.
SUMMERY OF THE UTILITY MODEL
In view of the not enough of prior art, the utility model aims to solve the technical problem that a preceding brake disc casting die cavity structure is provided, not only simple structure is reasonable, makes each time of filling the type of preceding brake disc foundry goods even moreover, effectively improves the yield.
In order to solve the technical problem, the technical scheme of the utility model is that: the utility model provides a preceding brake disc casting die cavity structure, includes the cope match-plate pattern body, the vertical cylindrical mould of watering that is provided with in cope match-plate pattern body center, this water mould lower extreme has set firmly square cope match-plate pattern, cope match-plate pattern body upper surface is concave downwards and is equipped with annular soup way mould, and this soup way mould ring is established at cope match-plate pattern periphery side, the upper surface equipartition of the cope match-plate pattern body of soup way periphery department has a plurality of dies of bursting.
Furthermore, a screw penetrates through the center of the bottom end of the upper template body from bottom to top and fixedly connects the upper template body with the pouring gate mold.
Further, the number of the riser dies is four.
Furthermore, four exhaust sheet dies are uniformly distributed on the upper surface of the upper template body.
Compared with the prior art, the utility model discloses following beneficial effect has: the front brake disc casting cavity is simple and compact in structure, original long soup channels are reduced to be annular, so that the pressure and the flow speed of molten metal entering the cavity can be improved, the time for filling each part of a front brake disc casting is uniform, and the yield of products is effectively improved.
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Drawings
Fig. 1 is a top view of an upper die plate body in an embodiment of the present invention;
fig. 2 is a schematic sectional view of a-a in fig. 1.
In the figure: 1-upper template body, 2-pouring channel mold, 3-upper section mold, 4-runner mold, 5-riser mold, 6-screw and 7-exhaust sheet mold.
Detailed Description
As shown in fig. 1-2, a front brake disc casting cavity structure comprises an upper template body 1, wherein a columnar runner mold 2 is vertically arranged in the center of the upper template body, a square upper section mold 3 is fixedly arranged at the lower end of the runner mold, an annular runner mold 4 is arranged on the upper surface of the upper template body in a downward concave manner, the runner mold is annularly arranged on the periphery of the upper section mold, and a plurality of belling molds 5 are uniformly distributed on the upper surface of the upper template body at the periphery of the runner mold.
The embodiment of the utility model provides an in, a screw 6 is worn to be equipped with from bottom to top at cope match-plate pattern body bottom center, and this screw links firmly the cope match-plate pattern body with water the mould together.
The embodiment of the utility model provides an in, the rising head mould is provided with four, and brake disc foundry goods is in the solidification process in the front, because the shrink and need certain metal liquid to carry out the feeding, so four rising heads have just played the feeding effect.
The embodiment of the utility model provides an in, go up the template body upper surface and still the equipartition have four exhaust piece moulds 7, because the template body is square, the extending direction of exhaust piece mould is respectively towards the four corners department of template.
The embodiment of the utility model provides an in when molding machine molding, fill the molding sand in the cavity that cope match-plate pattern body and cope flask are constituteed, form the sand mould promptly, form runner, hot runner, last die cavity, emit oral cavity, exhaust piece chamber in the sand mould promptly, and the homogeneous phase is led to, constitutes the sand mould die cavity.
The embodiment of the utility model provides an in, the corresponding lower bolster body that is provided with of cope match-plate pattern body, the lower mould of lower bolster body corresponds the setting with the cope match-plate pattern body's cope match-plate pattern, when molding sand mould down, need fill the molding sand in the cavity that lower bolster body and nowel are constituteed, because the structure that the sand mould was used in the cooperation is gone up to lower sand mould, and does not have the innovation in the structure, just do not do too much repetitious here.
The present invention is not limited to the above preferred embodiment, and any person can obtain the front brake disc casting cavity structure of other various forms under the teaching of the present invention. All the equivalent changes and modifications made according to the claims of the present invention shall fall within the scope of the present invention.
