Problems solved by technology
The disadvantages of the above-mentioned cross-flow wind blade middle section shaping machine are that the knocking head of the material removal device is only aimed at the center of the shaping core to knock, and when the middle section is inclined to rest on the shaping core, it is easy to hit the head. The inaccurate position of the knocking middle section leads to the scrapping of the middle section, resulting in a decrease in the finished product rate of the product

Embodiment Construction
[0018] Combine below figure 1 and figure 2 A detailed description will be made to the specific embodiment of the present invention.
[0019] The processing method of the middle section of the cross-flow fan blade is mainly completed by the production device of the middle section of the cross-flow fan blade. The production device of the middle section of the cross-flow fan blade is as follows: figure 1 and figure 2 As shown, the production device for the mid-section of the cross-flow blade includes an upper mold assembly 1 , a lower mold assembly 2 and a push rod assembly 3 arranged in a line from top to bottom.
[0020] The upper die assembly includes the upper die frame 11 and the handle punch 12 and the upper die spring 13, the handle punch 12 connected in the upper die frame 11 through the upper die spring 13 can be straight in the upper die frame 11 Lifting movement. The bottom of the upper die frame 11 is provided with a circular inner concave cavity 14 for accommod...

The invention relates to a machining method for a cross-flow fan blade middle segment for an air conditioner. The machining method for the cross-flow fan blade middle segment sequentially comprises the following steps that firstly, injection molding material liquid is injected in a disc forming cavity of a middle segment mold core, a blade forming cavity and a circular inner concave cavity in the bottom of an upper mold frame through an injection port of a material handle mold core; secondly, a cross-flow fan blade middle segment workpiece is formed; thirdly, the upper mold frame and a lower mold frame are vertically separated; fourthly, a material handle located right at the lower portion is cut off through a material handle punching head; fifthly, the material handle separated from a disc is ejected out through a material handle ejector rod, and the cross-flow fan blade middle segment with the material handle cut off is upwards ejected out through a middle segment ejector rod; and sixthly, the handle ejector rod and the middle segment ejector rod are reset, and mold assembling is finished after resetting of the upper mold frame and the lower mold frame. The machining method for the cross-flow fan blade middle segment has the beneficial effects that the efficiency of cutting off the material handle is high, and the machining yield of the cross-flow fan blade middle segment is improved.
Description
technical field [0001] The invention relates to a processing method for a middle section of a cross-flow fan blade for an air conditioner. Background technique [0002] The injection molding process of the middle section of the air-conditioning cross-flow fan blade is a key process in the manufacturing process of the fan blade. How to improve the processing efficiency of the middle section is what the fan blade manufacturers are striving for. At present, many wind blade manufacturers are equipped with manipulators for automatic processing and molding, and the manipulators take out the middle section from the injection mold. The middle section taken out of the injection mold is composed of a ring-shaped middle plate, a material handle and multiple blades. The multiple blades are arranged and fixed on the ring-shaped middle plate along the circumference, and the feed point of the material handle is fixed on the ring-shaped middle plate. superior. Finally, the material handl...
