Description of the Invention (i) The present invention relates to a method and a structure for forming a fan net cover, and more specifically, it relates to a combined forming method and structure of a fan net cover. The traditional electric fan is used to protect the front and rear mesh covers (1 Q) of the fan blades. Its composition is as shown in the first figure. Usually, most metal mesh strips (1 1) are matched with metal inner edge rings (1 2). And the outer edge ring (1 3) are welded into a mesh cover (1 0) type, and then through a combination of the ring (1 4) and the cover (15) (usually made of plastic), binding and setting It is formed on the outer edge ring (1 3) and inner edge ring (1 2) of the net cover (1 0). It is worth noting that after using the electric fan for a period of time, the fan blades and the cover net generally accumulate. A lot of dust is adsorbed, and it must be removed. For the user, removing the front and rear mesh covers and the binding bundle is different, but for the front and rear mesh covers of the fan and the combination binding ring. 1 It is quite difficult to operate, because the cards set on the binding ring: the smooth connection of the outer edge ring of the front net and the rear net, and the outer edge ring of the rear net cover can be connected; And 'the internal diameter of the combined bundle f is difficult to combine with the front and the assembly; ^ and it is a round-shaped evil person, so the combination is increased by welding ^ = f its gold The processing and time cost of the metal mesh and the inner and outer edge rings are quite expensive for the industry (the main ^ of the present invention cannot meet the real needs. The structure is mainly transparent: A 'lies in the provision of a fan network Cover molding steps, C. molding internal and external production A. material taking steps, B. placing a net bar into the mold and the oxen and outer ring are forming " ^ step & D. ^ _, It is connected to the two ends of the net strip, and it is structured in the wind. 5. Description of the invention (2) It belongs to the net cover. The formed fan net cover is made into σ, which has better strength, and the exemption = more in-work. In order to be close to the actual needs of the industry. Time-consuming and labor-intensive procedures, equipment? 1 = Invention technology used to achieve the above-mentioned purpose, Ming Diao: Gong: Zhang, here is a better feasible embodiment and match: η: Believe The above purpose, features and other aspects of the present invention are as follows: In-depth and specific understanding; first please refer to the first method: Method: Γ, ί a fan net molding provided by the embodiment of the invention. Mold step ㈡〇), C. molding inside (outside 2Λν i (4 0) and D. demoulding and taking part steps, etc .; ) This: = (20), take the pre-formed metal mesh strip (2, can be directly: from the head: metal mesh strip (2 1) is a fan net cover to take a very special; generally existing fan mesh (2 1) material, so the net bar is placed in the mold and the burdock q ^) is placed in the molding 2 in order. The above-mentioned net bar (21) is located in each net bar (2 t with mountain, the molding Moulds (3 1 inner and outer ring mold cavities (3 2 mn ;; ", which are provided with a connection "TΗ ::: ;; step: heart"), which is filled with plastic in the molding mold and the outer ring (412 to; Ministry (211) her ring " ... The step of removing the mold (50) 'Remove the mold and form the wind. Page 5 475975 V. Description of the invention (3) The finished fan net cover (5 1). As can be seen from the above description, the present invention mainly uses 1) to connect the inner and outer rings " 12) in the forming mold with the same time (3, that is, the two ends (211) of the net bar (2) are connected to the temple net盍 成. 口 口 (5 1); This will not only eliminate the time-consuming and labor-intensive procedures of traditional mesh strip = edge ring welding; it is worth noting that the finished fan net cover formed by the technology of the present invention
