Description

Technical Field

[0001] This application relates to the field of molding dies, and particularly to a molding die for preparing candle wicks. Background Art

[0002] A candle is a tool for daily lighting. It usually consists of a candle body and a wick vertically inserted inside. The candle body is mainly made of paraffin wax. By lighting the wick, the candle body can burn to emit light. With the wide popularization of electric lighting, candles are rarely used for daily lighting. Nowadays, most candles are used in activities such as birthday parties, religious festivals, collective mourning, weddings and funerals. Placing the candle in a delicate container to form a candle wick that lights up the dim environment can decorate the surrounding environment.

[0003] Nowadays, when the candle wicks installed in containers are processed and produced, they are usually processed and produced by the method of die casting. The melted wax oil is poured into the molding die and finally shaped into a candle wick product through cooling and shaping. After the shaping is completed, it is necessary to push the molded candle wick upward from below for demolding. However, due to the short molding and solidification time of the candle wick, the texture of the candle wick is not yet firm and tight enough. During the upward demolding process, the candle wick fits too tightly with the inner wall of the die. When the extrusion pressure at the bottom is too large, it is easy to cause the overall length of the candle wick to be compressed, resulting in abnormal deformation and affecting the product quality.

[0004] Therefore, a molding die for preparing candle wicks is proposed to solve some problems existing in the above-mentioned prior art. Summary of the Invention

[0005] The purpose of this application is to solve the problem that after the candle wick is molded in the prior art, during the upward demolding process, it is prone to abnormal deformation under excessive extrusion pressure, affecting the product quality.

[0012] Optionally, a hopper is fixedly provided on the outer sides of multiple upper collars, and an outer frame is fixedly welded at the edge position of the hopper. Horizontally arranged connecting plate a, connecting plate b, and connecting plate c are sequentially slidably installed inside the outer frame from top to bottom. Connecting plate a is fixedly connected to the outer side of the lower ends of multiple sleeves, connecting plate b is fixedly connected to the outer side of the lower ends of multiple outer connecting rods, and connecting plate c is fixedly connected to the outer side of the lower ends of multiple inner connecting rods.

[0013] Furthermore, multiple vertically arranged hanging racks are installed on the hopper from left to right in sequence, and a V-shaped card slot located directly above the central axis of the forming cavity is provided on the hanging rack. The upper end of the wick thread is clamped inside the V-shaped card slot. Vertical rods are fixedly connected to the front and rear ends of the hanging rack, and the lower ends of the vertical rods are fixedly welded to the edge of connecting plate c.

[0014] Furthermore, the lifting component includes upper fixing plates fixedly installed above the left and right sides of the outer frame, and vertical electric push rod a and electric push rod b are fixedly installed on the upper fixing plates.

[0016] Furthermore, a rotating shaft b located above the rotating shaft a is rotatably mounted inside the bracket, and guide wheels corresponding to the plurality of line rollers are fixedly mounted on the rotating shaft b, and the guide wheels are located directly below the inner connecting rod.

[0017] Compared with the prior art, the advantages of this application are:

[0018] (1) In the present application, a plurality of metal strips with outwardly protruding middle portions are assembled together, and the metal strips are pulled down to form a cylindrical molding cavity. After the candle wick is cast, the metal strips can be released to reset the middle portion thereof, and the metal strips can be automatically separated from the outer end wall of the molded candle wick, thereby reducing the clamping force of the molding cavity on the side end wall of the candle wick, thereby ensuring the stability of the candle wick when it is pushed up to be demolded, and avoiding the extrusion force being concentrated at the bottom of the candle wick to cause compression deformation thereof, which is beneficial to improving the product yield rate.

[0019] (2) By fixing the upper ring on the outside of the multiple metal strips, the inner end wall above the molding cavity can be kept unobstructed, and the upward demolding of the candle wick after molding can be ensured to be stable. At the same time, by fixing and welding the lower ring on the inside of the multiple metal strips, the connection of the internal connecting rod can be achieved, ensuring that the device can control the stretching and resetting of the metal strips conveniently and stably.

[0020] (3) A sleeve is provided which can be moved upward and sleeved on the outside of the plurality of metal strips, thereby restricting the outside of the molding cavity formed by the plurality of metal strips, further ensuring the tightness of the plurality of metal strips when they are stretched and spliced together, and to a certain extent ensuring the stability of the equipment when casting candle wicks.

[0021] (4) By opening a vertical through-channel between the top plate and the inner connecting rod, and cooperating with the wire-laying assembly installed below, the wick wire can be automatically placed by pulling, which is conducive to improving the efficiency and convenience of the equipment when loading the wick wire, thereby effectively improving its production efficiency.

[0022] (5) By embedding the sealing rubber ring inside the upper end of the channel and tightly wrapping the candle wick line, it is possible to prevent the wax oil from leaking downward through the channel during the casting process, which is beneficial to ensuring the stability of the candle wick casting. At the same time, the sealing rubber ring is made of high-temperature resistant rubber, which effectively improves the high-temperature resistance of the sealing rubber ring and reduces the thermal aging efficiency of the sealing rubber ring, which is beneficial to extending its service life.

[0023] (6) By fixedly installing the connecting plate a on the outer sides of multiple sleeves, the connecting plate b on the outer sides of multiple outer connecting rods, and the connecting plate c on the outer sides of multiple inner connecting rods, a unified control can be exerted over numerous metal strips, sleeves, and the top plate, ensuring the coordinated operation of multiple forming cavities within the device, which is conducive to enhancing the operational convenience of the device.

[0024] (7) By arranging the hanging rack above the hopper and providing a V-shaped groove on the hanging rack directly above the central axis of the forming cavity, the upper end of the wick line can be clamped and fixed, ensuring that the wick line is vertically arranged on the central axis of the forming cavity. This is conducive to ensuring the stable placement of the wick line during the casting process. At the same time, by fixedly connecting the hanging rack to the connecting plate c with a vertical rod, when the connecting plate c drives the top plate to move upward to push out the candle wick, the hanging rack can be driven to move upward synchronously, which is conducive to ensuring the stable and convenient reciprocating installation of the wick line.

[0025] (8) By guiding the wick line through the guide wheel installed on the rotating shaft b, the wick line can be vertically inserted through the channel, reducing the contact points between the wick line and the inner wall of the channel during the upward movement, avoiding breakage of the wick line due to excessive wear during movement, and being conducive to ensuring the stability of the upward wire release of the wick line.

Specific implementation manners

[0038] The embodiments will describe the technical solutions of the present application clearly and completely in conjunction with the accompanying drawings of the specification. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present application. Embodiment 1:

[0039] The present invention provides a molding die for preparing a candle wick. Please refer to Figure 1 - Figure 10 , which includes a plurality of mold bodies 1 evenly distributed in a matrix structure. The mold body 1 includes a plurality of metal strips 101 distributed in a surrounding manner, and the middle part of the metal strip 101 is set to an outwardly convex arc-shaped structure. The upper ends of the plurality of surrounding metal strips 101 are jointly fixed with an upper collar 102, and the lower ends of the plurality of surrounding metal strips 101 are jointly fixed with a lower collar 103. After the plurality of surrounding metal strips 101 are stretched straight downward, they are closely joined together to form a cylindrical structure, and the inside of the cylindrical structure forms a molding cavity. A lifting assembly is connected below the lower collar 103.

[0040] An upper plate 3 adapted to its internal dimensions is movably installed below the inside of the molding cavity, and a vertically downward extending inner connecting rod 301 is fixedly installed at the middle position of the bottom of the upper plate 3. The lower end of the inner connecting rod 301 is also connected with a lifting assembly, and a wick line 302 is placed on the central axis of the molding cavity.

[0041] During the use of the mold equipment, under the control of the lifting component, the lower end of the metal strip 101 is stretched downward. At this time, the multiple surrounding metal strips 101 are straightened, and adjacent metal strips 101 are in contact with each other, forming a cylindrical structure. With the sealing of the lower top plate 3, the cylindrical structure forms a molding cavity that is open at the top and closed at the bottom. The staff vertically places the wick line 302 on the central axis of the molding cavity, and then pours molten wax oil into the molding cavity from above, so that the wax oil fills the molding cavity and wraps around the outside of the wick line 302. After the wax oil cools and solidifies, a candle wick is formed. When demolding the formed candle wick, the lower end of the metal strip 101 is controlled by the lifting component to rise and reset. With the elastic deformation performance of the metal strip 101 itself, the middle part of the metal strip 101 bulges outward again, which makes the side wall of the metal strip 101 in contact with the candle wick separate from it. Then, the top plate 3 is controlled by the lifting component to rise upward, and the formed candle wick is pushed upward.

[0042] In this application, multiple metal strips 101 with outwardly protruding middle parts are surrounded and joined together. By pulling down the metal strips 101, a cylindrical molding cavity is formed. After the candle wick is cast and formed, by releasing the metal strips 101, the middle parts of them can be reset and automatically separated from the outer end wall of the formed candle wick, weakening the clamping force of the molding cavity on the side wall of the candle wick. Furthermore, the stability of the candle wick when it is pushed upward for demolding is ensured, and the extrusion force is prevented from concentrating at the bottom of the candle wick, resulting in its compression deformation, which is beneficial to improving the product qualification rate.

[0043] Please refer to Figure 2 , the upper collar 102 is fixedly sleeved on the outer sides of the upper ends of the multiple surrounding metal strips 101, and the lower collar 103 is fixedly sleeved on the inner sides of the lower ends of the multiple surrounding metal strips 101. An outer connecting rod 104 that is movably sleeved on the outer side of the inner connecting rod 301 is fixedly installed at the middle position inside the lower collar 103. During the use of this mold equipment, by fixedly sleeving the upper collar 102 on the outer sides of the multiple metal strips 101, the inner end wall above the molding cavity can be ensured to be unobstructed, and the stability of the upward demolding of the candle wick after molding can be ensured. At the same time, by fixedly welding the lower collar 103 on the inner sides of the multiple metal strips 101, the connection of the inner connecting rod 301 can be realized, and the convenient and stable stretching and reset of the metal strips 101 by this equipment can be ensured.

[0044] Please refer to Figure 1 and Figure 3, a sleeve 2 is movably sleeved on the outer sides of the lower ends of a plurality of circumferentially arranged metal bars 101, and the internal dimension of the sleeve 2 is adapted to the outer dimension of the cylindrical structure. The lower end of the sleeve 2 is connected with a lifting assembly. During the use of the die equipment, after the sleeve 2 is lifted, it can be sleeved on the outer sides of the plurality of metal bars 101 to limit the outside of the forming cavity formed by the plurality of metal bars 101, further ensuring the tightness of the fit when the plurality of metal bars 101 are stretched and joined, and to a certain extent ensuring the stability of the die equipment when casting the candle wick into shape.

[0045] Please refer to Figure 4 , Figure 6 and Figure 9 , a vertically penetrating channel is provided in the middle positions of the top plate 3 and the inner connecting rod 301. The wick line 302 movably penetrates through the channel from bottom to top. A wire releasing assembly is connected below the wick line 302. During the use of the die equipment, by providing a vertically penetrating channel in the middle positions of the top plate 3 and the inner connecting rod 301 and cooperating with the wire releasing assembly installed below, the wick line 302 can be automatically placed by pulling, which is beneficial to improving the high efficiency and convenience of loading the wick line 302 by the equipment, and thus effectively improving its production efficiency.

[0046] Please refer to Figure 2 and Figure 4 , a sealing rubber ring 303 wrapping the outer side of the wick line 302 is fixedly embedded in the upper port of the channel, and the sealing rubber ring 303 is made of high-temperature resistant rubber. During the use of the die equipment, by embedding the sealing rubber ring 303 in the upper end inside of the channel to tightly wrap the wick line 302, the leakage of wax oil through the channel during the casting process can be avoided, which is beneficial to ensuring the stability of the candle wick casting into shape. At the same time, by making the sealing rubber ring 303 of high-temperature resistant rubber, the high-temperature resistance performance of the sealing rubber ring 303 is effectively improved, and the heat aging efficiency of the sealing rubber ring 303 is reduced, which is beneficial to extending its service life.
