Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of molds, and in particular to a mold for a water receiving tray. Background Technology
[0002] Drain trays, as common water storage containers, are used in household appliances such as refrigerators and air conditioners, as well as some industrial equipment. Their main function is to collect condensate or overflow water generated during equipment operation. With the development of household appliances, higher requirements have been placed on the structural complexity, dimensional accuracy, surface finish, and production efficiency of drain trays.
[0003] In existing technologies, drip trays are mainly mass-produced using plastic injection molding, with the injection mold being the core equipment. However, in actual production applications, drip tray molds have the following technical problems: for example, during mold opening, the ejector plate ejects from a specific position on the drip tray, resulting in a single ejection position that easily causes the drip tray to become white, affecting its appearance; and each injection molding process can only produce one drip tray, leading to low production efficiency.

[0035] Combination Figures 1 to 5 As shown, this utility model provides a mold for a water receiving tray 30, which includes: a front mold 10, which has a front mold core 110; a rear mold 20, which has two rear mold cores 210, the two rear mold cores 210 and one front mold core 110 are combined to form two molding cavities 220, and the molding cavity 220 has a water receiving tray 30; an ejection mechanism, which is disposed on the rear mold 20; the ejection mechanism includes a central ejection mechanism 410 and two peripheral ejection mechanisms 420; the central ejection mechanism 410 is located between the two rear mold cores 210, and the central ejection mechanism 410 contacts and cooperates with the two water receiving trays 30; the two peripheral ejection mechanisms 420 are arranged one-to-one with the two rear mold cores 210, and the two peripheral ejection mechanisms 420 respectively contact and cooperate with the water receiving trays 30 on the two rear mold cores 210.
[0036] This application can produce two water receiving trays 30 in each injection molding process, and uses the central ejection mechanism 410 and two peripheral ejection mechanisms 420 to eject the two water receiving trays 30 simultaneously, thereby improving production efficiency. Compared with the prior art, this application increases the ejection positions of the ejection mechanism and the water receiving tray 30, and ejects the water receiving tray 30 from multiple positions, avoiding the problem of the water receiving tray 30 being ejected white due to a single ejection position.
[0037] In this embodiment, the water receiving tray 30 includes four side walls. One side wall of two opposing water receiving trays 30 is defined as the first side wall 310, and the remaining side walls are defined as the second side walls 320. Specifically, the water receiving tray 30 is composed of four side walls and a tray bottom. The opening of the water receiving tray 30 faces the rear mold 20. During mold closing, the two water receiving trays 30 are arranged left and right. The right side wall of the water receiving tray 30 on the left is the first side wall 310, and the other side walls are the second side walls 320. The left side wall of the water receiving tray 30 on the right is the first side wall 310, and the other side walls are the second side walls 320. The intermediate ejection mechanism 410 contacts and engages with the lower end of the first side wall 310; the peripheral ejection mechanism 420 contacts and engages with the lower end of the second side wall 320, so that the side walls of the water receiving tray 30 can be used to eject the water receiving tray 30.
[0038] In this embodiment, the intermediate ejection mechanism 410 includes an intermediate ejector plate 411 and an intermediate ejection rod 412. The upper end of the intermediate ejection rod 412 is connected to the intermediate ejector plate 411. The intermediate ejection rod 412 drives the intermediate ejector plate 411 to eject towards the front mold 10, thereby ejecting the two water receiving trays 30 simultaneously. The width of the intermediate ejector plate 411 is set to be greater than the distance between the two first side walls 310 of the two water receiving trays 30, ensuring that the first side walls 310 of the two water receiving trays 30 can be ejected.
[0039] In this embodiment, the two peripheral ejection mechanisms 420 are symmetrically distributed relative to the intermediate ejection mechanism 410 so as to correspond one-to-one with the water receiving tray 30.
[0040] Furthermore, each of the peripheral ejection mechanisms 420 includes a first peripheral ejector plate 421 and a first peripheral ejector rod 422, the upper end of the first peripheral ejector rod 422 being connected to the first peripheral ejector plate 421; the first peripheral ejector plate 421 is arranged parallel to the intermediate ejector plate 411, and the first peripheral ejector plate 421 and the intermediate ejector plate 411 are on the same plane, so that the first peripheral ejector plate 421 and the intermediate ejector plate 411 work together to eject the water receiving tray 30.
[0041] In this embodiment, each peripheral ejection mechanism 420 includes two second peripheral ejector plates 423 and two second peripheral ejection rods 424. The upper end of the second peripheral ejection rod 424 is connected to the second peripheral ejector plate 423. The two second peripheral ejector plates 423 are arranged perpendicularly to the middle ejector plate 411, and the two second peripheral ejector plates 423 and the middle ejector plate 411 are on the same plane, so that the second peripheral ejector plates 423 and the middle ejector plate 411 work together to eject the water receiving tray 30.
[0042] Preferably, the first peripheral ejector plate 421, the second peripheral ejector plate 423 and the middle ejector plate 411 can also work together to eject the water receiving tray 30 from the four side walls, thereby ejecting the water receiving tray 30 from multiple positions and avoiding the water receiving tray 30 from being ejected from a single position.
[0043] Furthermore, in the two peripheral ejection mechanisms 420, the two second peripheral ejector plates 423 located on the same side are connected as one unit by a connecting block 425. For example, the two second peripheral ejector plates 423 located on the front side are connected as one unit by the connecting block 423, which facilitates production and processing while enabling synchronous ejection.
[0044] Furthermore, the connecting block 423 and the intermediate ejector plate 411 are located on the same axis, and the connecting block 425 protrudes toward the intermediate ejector plate 411 so as to eject the connecting corner position of the first side wall 310 and the second side wall 320 using the connecting block 425.
[0045] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
