Embodiment Construction

[0034] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0035] In order to solve the problems in the prior art that the closed centrifugal impeller is difficult to demould and the qualified rate of finished products is low, the invention provides a closed centrifugal impeller casting device.

[0036] Such as Figure 1 to Figure 3 As shown, the closed centrifugal impeller casting device comprises a bottom mold part 10, a top mold part 20, a carbonyl core 40 and a push top 50, and the top mold part 20 is detachably buckled on the top of the bottom mold part 10, and the bottom mold part 10 is connected with the bottom mold part 10. A cavity 30 is formed between the top mold parts 20; there are multiple carbonyl cores 40, and multiple carbon cores 40 a...

Abstract

The invention provides a closed type centrifugal impeller casting device which comprises a bottom mould part, a top mould part, a plurality of carbonyl cores and an ejection part, wherein the top mould part is detachably buckled on the bottom mould part, and a cavity is formed between the bottom mould part and the top mould part; a plurality of the carbonyl cores are arranged in the cavity at intervals along the peripheral direction of the bottom mould part; and the ejection part is movably arranged on the bottom mould part, and one side, which faces the top mould part, of the ejection end of the ejection part extends to act or retracts into the bottom mould part. Because the ejection part is arranged, after the casting is completed, one side, which faces the top mould part, of the ejection end of the ejection part extends to act to eject a completely cast closed type centrifugal impeller from the bottom mould part so that the closed type centrifugal impeller is completely removed from the bottom mould part, so that the demoulding difficulty is reduced, the qualification rate of finished products is increased, and the problem of finished product damage caused by difficult demoulding is prevented.

Description

technical field [0001] The invention relates to the technical field of impeller casting equipment, in particular to a closed centrifugal impeller casting device. Background technique [0002] When casting a closed centrifugal impeller (which is a precision casting), since the impeller is a closed structure, the closed centrifugal impeller after casting and after casting is prone to defects, difficulty in demoulding, etc., resulting in product failure. Scrap, there is the problem of low casting success rate and low finished product pass rate. Contents of the invention [0003] The main purpose of the present invention is to provide a closed centrifugal impeller casting device to solve the problems in the prior art that the closed centrifugal impeller is difficult to demould and the qualified rate of finished products is low. [0004] In order to achieve the above object, the present invention provides a closed centrifugal impeller casting device, comprising: a bottom mold ...
