Detailed Description

Embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

As shown in fig. 5 to 9, an electronic candle includes a wax cartridge 10, an inner liner 20, and a movement 30. The liner 20 comprises an upper wall 21 and a side wall 22, and an interior space 23 enclosed by the upper wall and the side wall. A movement body 31 of the movement 30 is fixed to the inner space 23. The liner 20 is in this embodiment made of a translucent plastic material PP with an average wall thickness of 1.5 mm. The wax cylinder 10 is uniformly wrapped on the outer surface of the inner liner 20, and the average wall thickness of the wax cylinder 10 is 0.6-3 mm, in this embodiment, the wall thickness is 1.5 mm. The liner 20 includes a retaining buckle 24. The movement 30 comprises a light source 32, a flame head 33 and a movement body 31, wherein the movement body 31 comprises an escape position 311, a fixing position 312, a light source control circuit, a battery (power supply) and a switch, and the escape position 311, the fixing position 312, the light source control circuit, the battery (power supply) and the switch are arranged conventionally and are not shown in the figure. When assembling the movement 30 to the liner 20, the retaining buckle 24 on the liner 20 is first placed in the clearance 311, and then the liner 20 and the movement 30 are relatively rotated, so that the retaining buckle 24 on the liner 20 is rotated to the retaining position 312 to be retained. In this embodiment, the lining 20 further comprises a top fixing through hole 25, and the movement further comprises a top central fixing cylindrical surface 34, wherein the top central fixing cylindrical surface 34 is in contact with the top fixing through hole 25. The wax cylinder 10 is formed by directly cooling and solidifying melted wax on the outer surface of the lining 20, the outer surface of the wax cylinder is formed by the inner surface of a concave die, and the core body of the core is fixed in the inner space of the lining.

Fig. 10-16 illustrate a method of manufacturing an electronic candle. The production method comprises the use of at least two production moulds: a female die 40 and a male die 50. The female die 40 is used for molding the outer surface of the wax cylinder 10. In this embodiment, the male mold 50 is provided with a clearance groove 51 and a fixing groove 52, and the liner 20 is fixed on the male mold 50 by the following method: aligning the fixing button 24 on the liner 20 with the clearance groove 51 on the male die, moving the liner 20 from bottom to top until the fixing button 24 is flush with the fixing groove 52, and rotating the liner 20 until the fixing button 24 is clamped at the position of the fixing groove 52. The removable fixing of the liner and the male die may be a screw-fit or any other removable fixing.

In this embodiment, the concave mold 40 is made of a metal having good heat conductivity, such as an aluminum material. Preferably, the time for cooling and solidifying the wax water can be reduced, and the production efficiency is improved. FIG. 12 shows the mold opened state before molding. The liner 20 is secured to the male mold 50, the male mold 50 is positioned above the female mold 40, and a quantity of molten wax 60 is poured into the female mold 40. In this embodiment, the temperature of the wax liquid 60 before filling into the cavity is about 110 ℃. In this example, the formulation of the wax water is: 94% of a fully refined paraffin wax with the reference 58 +6% of AC6 (hard wax).

Fig. 13 shows a mold clamping state during molding. In this embodiment, the female mold 40 is held stationary and the male mold 50 is lowered vertically to a mold-closed state. In other embodiments, the male die may be kept stationary, and the female die may move vertically upward to a mold closing state, or both may move vertically and simultaneously toward each other to a mold closing state. In the present embodiment, the wax liquid 60 flows by being pressed in the process of the punch 50 moving down to the mold-clamped state, and finally flows in the shape of the wax cylinder in the mold-clamped state. The distance from the bottom surface 26 of the liner to the top surface 42 of the die is the height of the chute 41, which needs to be set to a height of 5 mm or more. In this embodiment, this height is 20 mm. The waste chute 41 is opened, and air can enter the waste chute 41 from the outside of the die 40 and the punch 50. Because the wax cylinder can shrink downwards in the cooling forming process, the bottom surface of the inner lining is formed into an uneven shape generally, the waste material groove can be designed to solve the problem, and the wax water poured into the female die can be ensured to be higher than the bottom surface of the inner lining and enter the waste material groove to form redundant waste wax in a die closing state when the wax cylinder is formed at each time. Further, the top of the waste tank cannot be sealed by the male die to form a closed space, so that external air is isolated from entering the waste tank, which can affect uniform shrinkage of wax water in a cooling process and cause reduction of the surface quality of the wax cylinder.

In the implementation, the time for cooling and solidifying the wax water to open the die is about 10 minutes, and compared with the cooling and solidifying time of 0.5-3 hours in the existing production mode, the forming efficiency is improved by many times.

Fig. 14 shows the mold-open state after molding. In this embodiment, the female mold 40 is kept stationary, and the male mold 50 vertically ascends to the mold opening state. The wax cartridge 10 together with the inner liner 20 is carried away from the female mold 40 by the male mold 50.

Fig. 15 shows a state where the wax cartridge 10 and the inner liner 20 are removed from the male mold 50. In this embodiment, the wax cylinder and the inner liner are rotated to rotate the fixing fastener 24 on the inner liner from the position of the fixing groove 52 on the male mold 50 to the position of the clearance groove 51, and then the wax cylinder 10 and the inner liner 20 are pulled out of the male mold.

Fig. 16 shows the resulting final desired wax cartridge and liner assembly after the excess wax waste 70 from the wax cartridge 10 has been removed from the bottom surface of the liner.

Fig. 17-22 illustrate another method of manufacturing an electronic candle. The production method includes the use of a female die 40 and an uncut liner 20. The female die 40 is used for molding the outer surface of the wax cylinder 10. In this embodiment, the female die 40 is provided with a clearance 45 and a fixing 46. Securing the uncut liner 20 to the female mold 40 by: and aligning the fixing buckle 24 on the outer surface of the uncut lining with the vacancy-avoiding position 45 on the female die 40, assembling the uncut lining 20 into the female die 40 from top to bottom, and then rotating the uncut lining until the fixing buckle 24 is clamped at the position of the fixing position 46. The reverse operation may remove the uncut liner 20 from the female mold 40.

Fig. 20 shows the mold opened state before molding. A quantity of molten wax 60 is poured into the female mold 40. In this embodiment, the temperature of the wax water before being poured into the female die is about 110 ℃, and the formula of the wax water is as follows: 94% of a fully refined paraffin wax with the reference 58 +6% of AC6 (hard wax).

Fig. 21 shows a mold clamping state during molding. The uncut liner 20 is fitted to the female die 40 while the uncut liner squeezes the wax water flow into a wax cylinder shape. Otherwise, the same procedure as in example 1 was repeated.

Fig. 22 shows the uncut liner 20 removed from the cavity die 40. After removal, the uncut liner was cut along the portion of the liner above the bottom surface 26 to provide a wax cylinder as shown in FIG. 16 of example 1.

The wax cylinder of the electronic candle is formed by directly cooling and solidifying melted wax water on the outer surface of an inner lining, and the outer surface of the wax cylinder is formed by the inner surface of a concave die. Preferably, the average thickness of the wax cylinder is 0.6-3 mm, and the wax cylinder with the average thickness within 3 mm has relatively small wall thickness, small wax consumption and short molding period, which is beneficial to improving the production efficiency, but the average thickness is less than 0.6 mm, so that the uniform and tidy surface effect is not easy to obtain.

Preferably, the liner is made of a translucent or transparent material. In the process of forming the wax cylinder, the combination of the wax cylinder and the outer surface of the lining is not necessarily completely compact, particularly, under the condition that the wall of the wax cylinder is very thin, when the outer surface of the wax cylinder is observed, the color of the area which is not closely combined is easily different from that of the area which is closely combined, and under the condition that the lining is made of semitransparent or transparent colorless or light-colored materials, the phenomenon that the color of the outer surface of the wax cylinder is not consistent can be greatly reduced, so that the appearance quality of a product is improved.

Preferably, the outer surface of the liner is rough rather than smooth, which may help the outer surface of the liner to better bond with the wax cartridge.

It should be understood that the above embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the same, and those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some technical features; and such modifications and substitutions are intended to be included within the scope of the appended claims.
