Embodiment 1

[0029] Such as image 3 , Figure 4 As shown, a stepped nozzle combination mold includes a core 1, which includes an undivided part 1-1 and a divided part 1-2. A thread 13 is provided at one end of the undivided part 1-1. 13 is connected to the inclined sleeve 30, which is in the shape of a bell mouth;

[0030] The core division part 1-2 is divided into two inner and outer layers, and the inner layer is the inner core 10;

[0031] The outer layer is the outer core 20. The outer surface of the outer core 20 is a stepped surface. The stepped surface is set for the suitable stepped nozzle. The outer core 20 includes two large outer cores 21 and two symmetrical to the inner core 10. The small outer core 22, at the upper end 23 of the outer core, that is, on the outside of the two small outer cores 22, is provided with symmetrically arranged side hole cores 40, the side hole core 40 is provided with a through hole 41, and the small outer core 22 corresponds to the side hole core The pos...

Abstract

The invention provides a staged nozzle combination mold and solves the problem of difficult mold stripping of the prior art. The adopted technical proposal is as follows: the staged nozzle combination mold comprises a middle core, one part of which is divided into an inner layer and an outer layer, the inner layer is an inner core, the outer layer is an outer core which comprises two large outer cores and two small outer cores which are arranged respectively and correspondingly, and the part of the middle core which is not divided is provided with an inclined sleeve at one end and a side hole core at the other end. The staged nozzle combination mold solves the key of staged nozzle production and fills the gap of mold design of refractory material, thus radically solving the problem of difficult forming of the staged nozzle and laying a foundation for mass production of the staged nozzle.

Description

Technical field [0001] The invention relates to the design of product moulds, in particular to a stepped nozzle combined mould. Background technique [0002] Because the inner hole of the stepped nozzle is stepped, it is difficult to manufacture and the added value of the product is high. If mass production is formed, it will bring immeasurable economic benefits to the enterprise. However, due to the complex shape of the stepped nozzle, demoulding cannot be achieved according to conventional thinking. Although "Foreign Refractories" has articles in this area many years ago, they are only hydraulic model test data. There has been no product in China. The key is that it cannot Solve the demolding problem. [0003] In order to solve the problem of mold release of the stepped nozzle, the present invention breaks the conventional thinking in design and provides a stepped nozzle combination mold, which solves the key to the stepped nozzle production and lays the foundation for the larg...
