Abstract
The utility model discloses a runner system for an investment casting process. The runner system mainly comprises a pouring cup, a straight runner and a filter net, is in a top casting type and is arranged on a wax module. The runner system is characterized in that the pouring cup, the straight runner, the filter net and a horizontal runner are connected in sequence from the top to the bottom; an inner pouring gate is arranged at the lower part of the horizontal runner; a riser is arranged on the horizontal runner; the lower part of the riser is connected with the wax module; a pressure head is arranged at the upper part of the riser. The top casting type runner system is adopted for processing aluminum or copper castings with relatively poor casting performance, the problem of overheat loosening easily caused at a water inlet part due to a bottom or side casting mode is solved, an effect of solidifying the castings from the bottom to the top during casting solidification is achieved, and thus the qualification rate of products is increased.
Description
Technical field
The utility model belongs to model casting technical field, the running channel of particularly using in investment casting process.
Background technology
Model casting is current comparatively common casting method, the casting dimension accuracy of producing is high, surface quality is good, and can produce other method and produce difficult large-scale complex component, the casting character of metal mainly contains mobility, shrinkage, air-tightness, casting stress, air-breathing property etc., it depends primarily on the composition of metal, but also with casting structure, casting factor, alloy heating-up temperature, the complexity of casting mold, running and feeding system, gate shapes etc. are relevant, as aluminium, the casting character of copper casting is poor, in process of setting, be prone to loose, the defects such as segregation crack, at present, adopt traditional bottom filling and side note formula group technology at water inlet position, to be prone to overheated loose, the qualification rate of product is lower.
Utility model content
The problem existing for solving prior art, the utility model provides the runner system of using in a kind of investment casting process, while having realized casting solidification, reach consecutive solidification mode from bottom to top, solved bottom filling and side note formula pouring type water inlet position and be prone to overheated loose.
The technical solution of the utility model is as described below:
The runner system of using in a kind of investment casting process, mainly by cup, sprue, screen pack etc., formed, runner system is top pouring type and is arranged on wax-pattern part, described cup, sprue, screen pack, cross gate connect from top to bottom successively, cross gate bottom is provided with ingate, the upper rising head that is also provided with of cross gate, rising head bottom is connected with wax-pattern part, and rising head top is provided with pressure head.
Advantage of the present utility model and beneficial effect are:
The utility model has adopted top pouring type runner system for the poor aluminium of casting character, copper casting, having solved bottom filling and side note formula pouring type water inlet position is prone to overheated loose, while having realized casting solidification, reach consecutive solidification mode from bottom to top, improved the qualification rate of product.
Accompanying drawing explanation
Fig. 1 is the main cut-away view of runner system of using in a kind of investment casting process of the present utility model;
In figure: 1-cup, 2-sprue, 3-pressure head, 4-rising head, 5-wax-pattern part, 6-support member, 7-ingate, 8-screen pack, 9-cross gate, 10-girth member
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, but the scope that should at this point not be interpreted as theme described in the utility model only limits to following embodiment, without departing from the idea case in the present invention described above, all various modifications, replacement and changes of making according to ordinary skill knowledge and customary means, include within the scope of the invention.
Embodiment mono-
As shown in Figure 1, the runner system of using in a kind of investment casting process, mainly by cup (1), sprue 2, screen pack 8 etc., formed, runner system is top pouring type and is arranged on wax-pattern part 5, described cup 1, sprue 2, screen pack 8, cross gate 9 connect from top to bottom successively, and cross gate 9 bottoms are provided with ingate 7, the upper rising head 4 that is also provided with of cross gate 9, rising head 4 bottoms are connected with wax-pattern part 5, and rising head top is provided with pressure head 3
In the present embodiment, can be according to concrete casting structure, the design shape of cross gate 9 and the arrangement of ingate 7.
In the present embodiment, can be according to concrete casting structure, wax-pattern part 5 bottoms arrange support member 6.
In the present embodiment, for strengthening the intensity of runner system, on described cross gate 9, be provided with girth member 10.
Embodiment bis-
As described in figure mono-, produce a kind of runner system of loop configuration aluminium alloy castings, this foundry goods height is in 300mm, described runner system is mainly by cup 1, sprue 2, screen pack 8 compositions such as grade, runner system is top pouring type and is arranged on wax-pattern part 5, wax-pattern part (5) and cross gate 9 loop configuration, cup 1, sprue 2, screen pack 8, cross gate 9 connects from top to bottom successively, on the circumference of cross gate 9 bottoms, be laid with four ingates 7 and four rising heads 4, rising head 4 bottoms are connected with wax-pattern part 5, rising head top is provided with pressure head 3, wax-pattern part 5 bottoms are provided with six support members.
Adopt the runner system of this enforcement aborning, efficiently solve bottom filling and side note formula pouring type water inlet position and be prone to overheated loosely, reach consecutive solidification mode from bottom to top while having realized casting solidification, casting qualified rate has been brought up to more than 90% by 30%.
