Detailed Description
In order to make the technical solutions of the present invention better understood and make the above features, objects, and advantages of the present invention more comprehensible, the present invention is further described with reference to the following examples. The examples are intended to illustrate the utility model only and are not intended to limit the scope of the utility model.
As shown in fig. 1 to 4, the present invention includes: the production method comprises the following steps of producing an upper half mould of an upper half wax mould and a lower half mould of a lower half wax mould, wherein the upper half mould and the lower half mould respectively comprise an upper mould 1, a middle frame 2 and a lower mould 3, the upper mould 1 is arranged on the top of the lower mould 3 through the sleeved middle frame 2, positioning points 8 are arranged on the opposite arc-shaped product surfaces between the upper mould 1 and the lower mould 3, the arc-shaped product surfaces of the upper mould 1 and the lower mould 3 are in profile modeling of a blade core, and a plurality of transverse grooves are further formed in the lower mould 3 to facilitate demoulding and ensure the strength of the wax mould; the upper half wax mould and the lower half wax mould are spliced in a positioning mode through positioning points 8.
In this embodiment, preferably, an upper positioning point 6 protruding downward is disposed on a side edge of the upper die 1 close to the middle frame 2, a lower positioning groove 7 is disposed at a position of the middle frame 2 corresponding to the upper positioning point 6, and the upper positioning point 6 and the lower positioning groove 7 are inserted into each other when being pressed.
In the present embodiment, at least 8 positioning points 8 are preferably provided.
By adopting the structure, the middle frame is sleeved on the lower die and positioned between the middle frame and the upper die, so that the upper die and the lower die are accurately positioned in the process of manufacturing the wax die.
In this embodiment, it is preferable that a rib 5 is provided in the hollow chamber.
