Problems solved by technology
[0003] In the prior art, the mold used to form this product is more complicated, because there are seven holes (six blade fixing holes and one axial through hole) in total on the blade fixing seat, and the blade fixing seat is integrally formed, the design of the mold When it is necessary to use seven pairs of core-pulling structures (or called sliders) to achieve
So many core-pulling mechanisms lead to a large mold design, but only one or two products can be produced each time the mold is opened, and the structure is very complicated
Therefore, the manufacturing cost of the blade fixing seat molding die on the existing water turbine is high, and the production efficiency is low.

Embodiment Construction
[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0023] refer to Figure 2-Figure 10 As shown, a blade fixing seat forming mold on a water turbine includes a male mold 1 and a female mold 2. The joint surface of the male mold 1 and the female mold 2 is provided with a blade fixing seat 9 left half molding cavity and a blade fixing seat 9 Right half cavity. That is, the present invention mold opening obtains the left half part ( Figure 8 ) and the right half ( Figure 9 ), and then combine the obtained left half with the half to form an integral blade holder 9, such as Figure 10 shown.
[0024] The joint surface of the male mold 1 and the female mold 2 is provided with a blade fixing seat 9 and the left half of the molding cavity means that the male mold 1 is provided with at least one first assembly, and the first assembly is composed of the first insert pin 3.1, six The first rib 3.2 ...

The invention discloses a forming mold for a blade fixed seat on a water turbine and belongs to the technical field of molds. The forming mold comprises a male mold and female mold, wherein a left half forming cavity and a right half forming cavity of the blade fixed seat are arranged on the joint surface of the male mold with the female mold. According to the forming mold, the blade fixed mold is formed by the left and right portions, the left half and right half portions are combined together to form a whole blade fixed seat. During the design of the mold, when fixing holes of six blades of the blade fixed seat are formed, six core-pulling mechanisms are not needed, grooves with semicircular sections are formed on the left half and right half portions respectively and combined together to form a blade fixing hole. Due to omission of the core-pulling mechanisms, the mold is simple in structure, low in production cost and small in size simultaneously; a plurality of blade fixed seats can be formed by using the mold in the same size once, the mold can form eight blade fixed seats once, and the productivity efficiency is improved.
Description
technical field [0001] The present invention relates to a mold, more specifically to a blade fixing seat forming mold on a water turbine Background technique [0002] Such as figure 1 The product shown is a blade fixing seat on a water turbine, which belongs to the field of science and education, and is used as a component on a water turbine for students to do experiments or demonstrations in the classroom. The blade fixing seat on the water turbine includes a body with an axial through hole, and a plurality of blade fixing holes in the radial direction on the body, generally six, arranged circularly at intervals of 60 degrees. [0003] In the prior art, the mold used to form this product is more complicated, because there are seven holes (six blade fixing holes and one axial through hole) in total on the blade fixing seat, and the blade fixing seat is integrally formed, the design of the mold When it is necessary to use seven pairs of core-pulling structures (or called sl...
