Description

Technical Field

[0001] The utility model relates to the technical field of wax ring flange processing and production molds, in particular to a wax ring flange mold which is convenient for demoulding. Background Art

[0002] Flanges are commonly known as sealing rings, also called gaskets. Many rubber pads used between industrial bearings for shock absorption and wear prevention are called flanges. The most common flange is a wax sealing ring, which is also called a wax seal ring as the name suggests. It is installed on the toilet drain outlet. Flanges are basically required for toilet installation. The toilet flange (toilet sealing ring) is placed between the drain outlet and the toilet drain hole to play a sealing role, so that the siphon toilet does not leak and the flushing effect is also very good.

[0003] In the existing wax ring flange production process, the rubber mold is fixed in the aluminum mold by screwing in bolts, and liquid wax is poured into the rubber mold to fix the mold. However, after the wax ring is formed, the rubber mold needs to be taken out and then the wax ring is demolded. The bolt screwing method reduces the demolding efficiency and is inconvenient to operate. Therefore, a wax ring flange mold that is easy to demold is needed to meet the demand. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 A wax ring flange mold for convenient demoulding comprises a base plate 1 and a wax ring flange 2, an outer mold 3 is movably mounted on the base plate 1, a mounting hole 4 is opened on the outer mold 3, a spring 5 is connected at the center of the mounting hole 4, a pad 6 is connected to the top of the spring 5, an inner mold 7 is movably mounted in the mounting hole 4, the inner mold 7 is located on the pad 6, the wax ring flange 2 is located in the inner mold 7, a screw 8 is threadedly connected to the base plate 1, the screw 8 passes through the inside of the spring 5, the pad 6 and the center of the inner mold 7 and extends upward, a connecting shaft 9 is arranged on the top of the screw 8, the outer diameter of the connecting shaft 9 is smaller than the outer diameter of the screw 8, a cam handle 10 is rotatably mounted on the outer wall of the connecting shaft 9, a notch gasket 11 is inserted on the outer wall of the connecting shaft 9, and the notch gasket 11 is located between the top of the inner mold 7 and the bottom of the cam handle 10.

[0022] Before making the wax ring flange 2, place the outer mold 3 on the base plate 1, pass the screw 8 through the backing plate 6 and the outer mold 3, and screw it into the base plate 1 to provide positioning for the outer mold 3. At this time, turn the cam handle 10 so that the cam handle 10 is in a vertical state, pass the clean inner mold 7 through the cam handle 10, put it into the mounting hole 4, and place it on the backing plate 6 to press up and down to compress the spring 5. At this time, align the notch of the notch gasket 11 with the connecting shaft 9 and insert it, and turn the cam handle 10 so that The cam is in contact with the notch gasket 11 and presses down the notch gasket 11 to press the inner mold 7 tightly into the outer mold 3, put the plastic part into the mold cavity of the inner mold 7, pour the wax liquid, and after it is solidified and formed, rotate the cam handle 10 so that the cam removes the pressure on the notch gasket 11, so that the outer mold 3 and the inner mold 7 can move, place the cam handle 10 vertically, pull out the notch gasket 11, take out the inner mold 7 from bottom to top, and then remove the inner mold 7 to complete the demolding after the wax ring flange 2 is made.

[0023] Specifically, in this embodiment, the outer mold 3 is an aluminum mold, and the inner mold 7 is a rubber mold. The aluminum outer mold 3 can provide a complete external shape for the wax ring flange 2, and the rubber inner mold 7 facilitates the demolding of the wax ring flange 2 after production.

[0024] Specifically, in this embodiment, a threaded hole 12 is opened on the base plate 1, and the screw 8 is threadedly connected in the threaded hole 12. The threaded hole 12 ensures the connection between the screw 8 and the base plate 1, and the clamping force of the cam handle 10 can be adjusted according to the depth of the screw 8 being screwed in.

[0025] Specifically, in this embodiment, a first through hole 13 is opened on the bottom end of the mounting hole 4, a second through hole 14 is opened on the pad 6, and a third through hole 15 is opened on the inner mold 7. The apertures of the first through hole 13, the second through hole 14 and the third through hole 15 are the same and are slightly larger than the outer diameter of the screw 8, which facilitates the screw 8 to pass smoothly through the inner mold 7, the pad 6 and the outer mold 3.

[0026] Specifically, in the present embodiment, a support shaft 16 is provided on the outer wall of the connecting shaft 9, and the cam handle 10 is rotatably mounted on the support shaft 16 at a position deviating from the center of the circle. The length of the support shaft 16 is smaller than the inner diameter of the third through hole 15 on the inner mold 7, so that the cam of the cam handle 10 can rotate eccentrically, thereby realizing the compression and separation of the slot gasket 11, and allowing the inner mold 7 to pass smoothly through the cam handle 10, thereby facilitating the removal and placement of the inner mold 7.

[0027] Specifically, in this embodiment, the outer diameter of the notch gasket 11 is greater than the inner diameter of the third through hole 15 on the inner mold 7 , so that the notch gasket 11 can be pressed onto the inner mold 7 .

[0028] Specifically, in this embodiment, a rubber ring 17 is sleeved on the outer wall of the connecting shaft 9. The rubber ring 17 is located between the bottom end of the cam handle 10 and the top end of the slotted gasket 11. The outer diameter of the rubber ring 17 is smaller than the inner diameter of the third through hole 15 on the inner mold 7. The rubber ring 17 increases the friction between the slotted gasket 11 and the cam handle 10 to prevent the cam handle 10 from rotating under pressure.

[0029] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
