Embodiment 1

[0029] Such as image 3 , Figure 4 As shown, a stepped nozzle combination mold includes a central core 1. The central core 1 includes an undivided part 1-1 and a divided part 1-2. One end of the undivided part 1-1 is provided with a thread 13. Through the thread 13 connect the inclined sleeve 30, and the inclined sleeve 30 is in the shape of a bell mouth;

[0030] The split part 1-2 of the core is divided into two layers inside and outside, and the inner layer is the inner core 10;

[0031] The outer layer is the outer core 20, and the outer surface of the outer core 20 is a stepped surface. Small outer core 22, at outer core upper end 23 places, be positioned at the outside of two small outer cores 22, be provided with symmetrically arranged side hole core 40, be provided with through hole 41 in the middle of side hole core 40, the corresponding side hole core of small outer core 22 The position is provided with a through hole 22-1, and the corresponding position of the i...

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 combinationmold 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 holecore 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 product mold design, in particular to a stepped nozzle combination mold. 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 it is mass-produced, it will bring immeasurable economic benefits to the enterprise. However, due to the complex shape of the stepped nozzle, it is impossible to achieve demoulding according to conventional thinking. Although "Foreign Refractory Materials" has an article on this aspect many years ago, it is only hydraulic model test data, and no product has been formed in China. The key is that it cannot Solve the demoulding problem. [0003] In order to solve the demoulding problem of the stepped nozzle mold, the present invention breaks the conventional thinking in design and provides a stepped nozzle combination mold, which solves the key to the production of the stepped nozzle and lays the...
