Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a multi-cavity mold for a wavy dinner plate. Background Art

[0002] The unique design of the wavy pattern dinner plate, with its wavy edges, is not only aesthetically pleasing but also effectively prevents food from spilling, keeping the table tidy. The wavy texture also increases the plate's slip resistance, making food more stable and less likely to slip. The multi-cavity mold for wavy pattern dinner plates is a mold specifically designed for producing wavy pattern dinner plates. Its unique feature is that it has multiple chambers, allowing for the simultaneous production of multiple plates with the same or different wavy patterns.

[0003] After checking the publication number: CN220482493U, a plate injection mold is disclosed. This technology discloses "a plate injection mold. The utility model includes a plate molding injection lower mold and a plate molding injection upper mold. The plate molding injection upper mold is provided with an injection molded part above, and the plate molding injection lower mold is provided with a plate molding protrusion." The technical scheme has the following effects: "During the injection molding process, the plate molding injection lower mold and the plate molding injection upper mold are brought close to each other, so that the plate stripe synchronous molding component and the plate molding protrusion are abutted and matched to form a complete mold cavity. The molten material is injected into the mold cavity through the injection molded part, and the plate stripe synchronous molding component is used to synchronously mold the stripe structure at the bottom of the plate. The molding precision is high and no secondary processing is required. After the injection molding is completed, cooling water is injected into the annular cooling part. The annular structure is adopted to achieve a good cooling effect."

[0004] When the mold on the injection molding machine is about to be completely closed, the injection molding machine will apply higher pressure and speed to straighten the machine hinge and complete the mold closing action. Repeated use may cause slight displacement or deformation of the mold, resulting in poor sealing after mold closing, which may further affect the stability of the process and the quality of the injection molded parts. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a multi-cavity mold for a wavy dinner plate. When the mold is closed, the shaft plate flips inward, and at the same time, the shaft plate drives the upper inclined block to squeeze the lower inclined block, which can not only fill the tiny gaps that may exist after the mold is closed, but also effectively prevent the leakage of molten plastic during the injection molding process; when the mold is opened, the shaft plate flips outward, and at the same time, the shaft plate drives the upper inclined block to separate from the lower inclined block, avoiding movement interference with the mold opening.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a multi-cavity mold for a wavy dinner plate includes a fixed mold, a fixed mold base fixed at the bottom of the fixed mold, a movable mold installed at the upper end of the fixed mold base, and a movable mold base fixed at the top of the movable mold. The fixed mold base is provided with a sealing mechanism for further sealing after the mold is closed. The sealing mechanism includes:

[0007] The actuator assembly includes shaft seats fixed to the outer walls of the left and right ends of the fixed mold base, shaft plates hinged at the outer ends of the shaft seats, upper inclined blocks installed above the inner walls of the shaft plates, and lower inclined blocks fixed on both sides of the top of the movable mold base;

[0008] The mounting components are installed at the upper and lower ends of the mold and are used to install the mold on the injection molding machine.

[0010] Preferably, the actuator assembly further comprises waist-shaped holes provided on both sides of the interior of the shaft plate, and the shaft plate is fixed to the upper bevel block by bolts through the waist-shaped holes.

[0011] Preferably, the mounting assembly includes lower uprights fixed at the four corners of the bottom of the fixed mold base, a lower mounting frame fixed between the bottoms of the four lower uprights, upper uprights fixed at the four corners of the top of the movable mold base, and an upper mounting frame fixed between the tops of the four upper uprights.

[0012] Preferably, an inclined surface is provided below the inner end of the upper inclined block, and an inclined surface is provided above the outer end of the lower inclined block, and the inclined surface on the upper inclined block matches the inclined surface on the lower inclined block.
