Rotary core-pulling mold for manufacturing turbine

Abstract

A rotary core-pulling mold for manufacturing a turbine comprises an upper mold plate and a lower mold plate, wherein a sliding base is arranged in the lower mold plate, a first sliding block and an inclined guide column are arranged on the sliding base, the inclined guide column penetrates through the first sliding block and is connected with the upper mold plate, and the first sliding block is provided with a first mold core used for forming turbine blades; a second sliding block abutting against the first sliding block is further arranged in the sliding base, the second sliding block is provided with a second mold core forming turbine blades, a rotary disc is arranged in the lower mold plate, the rotary disc is connected with the sliding base, and the rotary disc is connected with a driving mechanism; a mold core seat is arranged in the lower die plate, the mold core seat extends to form a third mold core of a turbine inner hole, and the first mold core, the second mold core and thethird mold core form a cavity. First core pulling is conducted on the upper half portion of the turbine blade through the first sliding block and the inclined guide column, second rotary core pullingwhich drives the first sliding block and the second sliding block to be outwards pulled out in the arc-shaped track direction of the turbine blade at the same time is achieved through the rotary disc,it is guaranteed that mold cores and a product are completely separated, and smooth mold stripping of the product is achieved.

Description

technical field [0001] The invention relates to the field of molds, in particular to a rotating core-pulling mold for manufacturing turbines. Background technique [0002] A turbine, a fan in a car or airplane engine, improves engine performance by blowing fuel vapor into the engine using exhaust gas. A turbine is a rotating power machine that converts the energy of a flowing working medium into mechanical work. It is one of the main components of aero-engines, gas turbines and steam turbines. [0003] Existing turbines are mainly manufactured through injection molds, and since turbines are mainly composed of blades, and most of the general blades have a barb structure, most of them are set in the form of sliders for core-pulling design to prevent products from being separated from each other when the mold is opened. The mold kernel interferes and damages the product. And the blades generally have an inclination angle, so most of the blades are divided into two mold cores ...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned turbines are basically turbines with fewer blades, and the inclination angle of the above-mentioned turbine blades is also relatively small, and the track of the turbine blades is also relatively single. When the existing mold uses the above-mentioned first slider and second slider for flat-drawing core-pulling, it may still cause the mold core to interfere with the product and damage the product
