Description

Technical Field

[0001] This utility model specifically relates to the field of fan mold technology, and more specifically to a multi-functional combined fan filter integrated molding mold. Background Technology

[0002] To protect the rotating blades inside the fan, a filter is usually installed on the outside of the fan. The integrated mold for the fan and filter can mold the fan and filter at the same time, which greatly reduces the production process and time. Compared with the traditional method of manufacturing the fan and filter separately and then assembling them, the integrated mold can significantly improve production efficiency and reduce production costs.

[0003] However, in practice, it has been noted that filter elements produced by the commonly used one-piece molding mold have relatively large gaps. When producing filter elements with smaller gaps, the structure of the filter elements is mostly an array of holes, which is relatively complex. Therefore, demolding the mold after molding is more troublesome. Workers need to apply release agent inside the mold or frequently knock the mold during demolding to separate them. Frequent knocking can easily damage the mold and cause mold damage. In subsequent production, it is impossible to meet the requirement of rapid demolding after one-piece molding of small gap filter elements. Utility Model Content

[0063] In this embodiment, the end of the punch 51 away from the casting hole 53 is provided with a sliding groove 54 corresponding to the rectangular groove 33. Both sides of the punch 51 are integrally provided with inclined plates 55 corresponding to the inclined groove 34, and the inclined plates 55 are slidably connected to the inner side of the inclined groove 34. The punch 51 is placed on the inner upper side of the hollow frame 31, and the inclined plates 55 on the side of the punch 51 are aligned with the upper side of the inclined groove 34. The punch 51 is tilted and moved until the inclined plates 55 are completely inserted into the inclined groove 34, thereby restricting the position of the punch 51.

[0064] In this embodiment, the punch 51 is provided with a symmetrical mating groove 52 at one end near the casting hole 53, and a U-shaped connecting plate is placed between the two punches 51. Both ends of the U-shaped connecting plate are inserted into the mating groove 52 to position the connection.

[0065] In this embodiment, the mounting hole template 6 includes a hollow end plate 61. The bottom of the hollow end plate 61 is provided with insertion posts 64 in a rectangular array, and the ends of the insertion posts 64 are inserted into the insertion holes 24 through the holes 32.

[0066] In this embodiment, both sides of the hollow end plate 61 are provided with positioning protrusions 63 corresponding to the rectangular groove 33 and the sliding groove 54, and the positioning protrusions 63 on both sides are slidably connected to the rectangular groove 33 and the sliding groove 54 respectively.

The hollow end plate 61 is inserted into the hollow frame 31, and the side of the hollow end plate 61 is in contact with the punch 51.

[0068] The working principle of this utility model is as follows: First, all components are assembled. The modular modules 711 are installed in a circular array on the outside of the fixed disc 721, and the spacer protrusions 712 on the side of the modular modules 711 are inserted into the appropriate side slots 724. Then, the outer mold 71 and the inner mold 72 are placed into the conical groove 22, and the positioning pins 713 at the bottom of the modular modules 711 are inserted into the corresponding positioning holes 25 for positioning. Next, the sealing cover 73 is fitted onto the inner mold 7, and the semi-circular channel 73 at the bottom of the sealing cover 73 is aligned with the casting groove 723 in the inner mold 72. Then, the split frame 3 is symmetrically placed on the filter screen bottom mold 2. Next, the punch 51 is placed on the inner upper side of the hollow frame 31, and the inclined plate 55 on the side of the punch 51 is aligned with the upper part of the inclined groove 34. The punch 51 is tilted and moved until the inclined plate 5 is fully inserted into the inclined groove 34. At this time, the casting hole 53... The hollow end plate 61 is inserted into the gap between the hollow frame 31 and the punch 51, and the positioning protrusions 63 are inserted into the corresponding rectangular grooves 33 and sliding grooves 54. The split frame 3, split top mold 5 and mounting hole template 6 are firmly combined together by mortise and tenon structure. Then the retainer 1 is attached to the outside of the split frame 3, and the L-shaped claws 4 are attached to the top of the split frame 3 and the mounting hole template 6 to limit the connection. Then the retainer 1 and the filter screen bottom mold 2 are connected by bolts, and the ends of the bolts are respectively stuck in the bolt grooves 23 to limit the connection. Finally, the split mold base 8 is inserted into the lower groove 28 at the bottom of the mold base 2, and the ends of the array protrusions 81 are inserted into the bottom slot 725 through the through groove 26. Then the material is melted and introduced into the mold. Since the multiple positions of the mold are spliced ​​together by combination, it is more convenient to split the mold.

[0069] During disassembly, the split mold base 8 and the retainer 1 are removed first, and then the mounting hole template 6, the split top mold 5 and the split frame 3 are removed in sequence. Finally, the molded fan filter and the split filter screen mold 7 are taken out as a whole. The modular module 711 is designed to be composed of multiple parts, which makes it easy to quickly separate the molded filter screen from the modular module 711. After removing the sealing cover 73, it is convenient to clean the material inside the casting groove 723 in a timely manner, which further facilitates the demolding of workers. The structure is simple, the operation is very convenient, and the labor intensity is effectively reduced.
