The two sets of support plates are rotatably connected to the lower mold on one side surface of the support frame. A flipping assembly is provided between the two sets of support plates.

[0011] As a preferred embodiment of the height-adjustable injection mold for household appliances described in this utility model, the flipping assembly includes a rotating rod rotatably connected to two sets of support plates, and a gear 1 is fixedly connected to the middle surface of the rotating rod. A rack plate 1 is meshed with one side of the gear 1 and is fixedly connected to the support frame. Gear 2 is fixedly connected to both ends of the rotating rod, and rack plate 2 is meshed with the lower surface of the gear 2. Slide grooves are opened inside the two sets of rack plates 2, and connecting parts are slidably connected to the inner wall surface of the slide grooves. The upper surface of the two sets of connecting parts is fixedly connected to the support plate. Support rods are fixedly connected to the adjacent side surfaces of the two sets of rack plates 2, and the upper surface of the support rods is movably connected to the lower surface of the lower mold.

[0012] As a preferred embodiment of the height-adjustable injection mold for household appliances described in this utility model, the ends of the two sets of support rods away from the side fixing plates are all designed in an arc shape, and the arc-shaped surfaces are movably connected to the lower surface of the lower mold.

This causes the lower mold, which is rotatably connected to the support plate, to move downward synchronously. At the same time, the rotating rod, which is rotatably connected to the support plate, moves gear one downward, causing gear one to rotate on the surface of rack plate one. The rotating rod, which is fixedly connected to gear one, drives gear two to rotate simultaneously. The rack plate two, which meshes with gear two, causes the support rod to slide on the lower surface of the lower mold. This causes the lower mold to slide on the arc-shaped surface of the support rod, causing the lower mold to flip downward. This makes the circular plate contact the surface of the support frame. The sliding rod, which is fixedly connected to the circular plate, slides inside the lower mold, causing the push-pull component to push out the appliance parts, which fall onto the surface of the guide plate and slide along the surface of the guide plate to the designated storage location. This allows the processed appliance parts to be quickly stored without additional steps to remove them separately, effectively improving processing efficiency. Attached Figure Description

[0029] The main unit 100 includes a support frame 101. A lifting seat 104 is provided on the lower surface of the support frame 101 to adjust the height of the support frame 101. An upper mold 102 is fixedly connected to one side surface of the support frame 101, and a lower mold 103 is provided on the lower surface of the upper mold 102. An injection pipe is opened on one side of the upper mold 102.

[0030] The unloading unit 200 includes a side plate 201 fixedly connected to the support frame 101. A motor 202 is fixedly connected to the surface of the side plate 201, and a threaded rod 203 is fixedly connected to the output shaft of the motor 202. The surface of the threaded rod 203 is rotatably connected to the side plate 201. A lifting rod 204 is threadedly connected to the surface of the threaded rod 203, and support plates 205 are fixedly connected to both ends of the lifting rod 204. The two sets of support plates 205 are rotatably connected to the lower mold 103 on one side surface of the support frame 101. A flipping component 206 is provided between the two sets of support plates 205. The motor 202 drives the threaded rod 203 to rotate, thereby causing the lifting rod 204 and the support plate 205 to move the lower mold 103 downward, so that the lower mold 103 and the upper mold 102 exit the mold closing mechanism.

[0031] The flipping assembly 206 includes a rotating rod 206b rotatably connected to two sets of support plates 205. A gear 206a is fixedly connected to the middle surface of the rotating rod 206b. A rack plate 206c is meshed with one side of the gear 206a and is fixedly connected to the support frame 101. Gears 206d are fixedly connected to both ends of the rotating rod 206b, and rack plates 206e are meshed with the lower surfaces of the gears 206d. Both sets of rack plates 206e have internal openings. There is a slide groove 206f, and the inner wall surface of the slide groove 206f is slidably connected with a connector 206g. The upper surface of the two sets of connectors 206g is fixedly connected to the support plate 205 to support the rack plate 206e. The adjacent side surfaces of the two sets of rack plates 206e are fixedly connected with a support rod 206h, and the upper surface of the support rod 206h is movably connected to the lower surface of the lower mold 103. The lower mold 103 can move downward and flip downward at the same time, so that the home appliance parts inside the lower mold 103 are exposed.

[0032] Furthermore, the ends of both sets of support rods 206h that are away from the side plate 201 are designed in an arc shape, and the arc surfaces are movably connected to the lower surface of the lower mold 103, so that the lower mold 103 can be rotated along with the arc surface.

[0033] Furthermore, a fixing plate 207 is rotatably connected to the surface of the threaded rod 203, and one side surface of the fixing plate 207 is fixedly connected to the support frame 101. Two sets of limiting rods 208 are fixedly connected to the upper surface of the fixing plate 207, and the surface of the limiting rods 208 is slidably connected to the lifting rod 204, thus having a limiting function.

[0034] Furthermore, a slide rod 107 is slidably connected inside the lower mold 103, and a push-pull member 108 is fixedly connected to the upper end of the slide rod 107. A circular plate 109 is fixedly connected to the lower end of the slide rod 107, and a spring 110 is fixedly connected to one side surface of the circular plate 109. The other end of the spring 110 is fixedly connected to the lower mold 103. When the lower mold 103 is flipped downward, the circular plate 109 can contact and fit with the support frame 101, and then the slide rod 107 pushes the push-pull member 108 to slide, pushing out the home appliance parts inside the lower mold 103.

[0035] Furthermore, a guide plate 105 that mates with the lower mold 103 is fixedly connected to one side surface of the support frame 101, and the guide plate 105 is wedge-shaped so that the accessories fall on the surface of the guide plate 105 and then slide to the designated storage location.

[0036] During use, after injection molding is completed, the motor 202 is started by powering on the motor to drive the threaded rod 203 to rotate. The lifting rod 204, which is threadedly connected to the threaded rod 203, drives the support plate 205 to move downward. This causes the lower mold 103, which is rotatably connected to the support plate 205, to move downward synchronously. Simultaneously, the rotating rod 206b, which is rotatably connected to the support plate 205, drives gear 206a to move downward, causing gear 206a to rotate on the surface of rack plate 206c. The rotating rod 206b, which is fixedly connected to gear 206a, drives gear 206d to rotate simultaneously. The 6d meshing rack plate 206e drives the support rod 206h to slide on the lower surface of the lower mold 103, causing the lower mold 103 to slide on the arc-shaped surface of the support rod 206h, thereby causing the lower mold 103 to flip downwards and the circular plate 109 to contact the surface of the support frame 101. The slide rod 107, which is fixedly connected to the circular plate 109, slides inside the lower mold 103, causing the push-pull component 108 to push out the home appliance parts, which fall onto the surface of the guide plate 105 and slide along the surface of the guide plate 105 to the designated storage location, so that the processed home appliance parts can be taken out separately without additional procedures.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
