Description

Technical Field

[0001] This invention relates to the field of faucet casting technology, and in particular to a faucet casting mold and a faucet casting device. Background Technology

[0002] As is well known, faucets are now mostly produced using casting methods, and faucet casting molds are indispensable in the casting process. Currently, when molten copper is poured into the faucet casting mold, the flow rate of the molten copper is too fast and the flow is uneven, resulting in poor faucet casting quality. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a faucet casting mold that can improve the casting effect of faucets.

[0004] The present invention also proposes a faucet casting device having the above-mentioned faucet casting mold.

[0005] According to an embodiment of the present invention, a faucet casting mold includes a first mold unit, a second mold unit, and a sand core. The first mold unit has a first cavity, which includes a first main casting channel, a first inlet pipe casting channel, and a first outlet pipe casting channel. The first main casting channel has a first casting port communicating with the outside, and a plurality of spaced first protrusions are provided on the edge of the first main casting channel. The edges of the first protrusions are arc-shaped, and the plurality of first protrusions define a first flow channel and a second flow channel. The first flow channel connects the first main casting channel and the first inlet pipe casting channel, and the width of the first flow channel gradually increases along the direction from the first main casting channel to the first inlet pipe casting channel. The second flow channel connects the first main casting channel and the first outlet pipe casting channel, and the width of the second flow channel gradually increases along the direction from the first main casting channel to the first outlet pipe casting channel. The second mold unit has a second cavity symmetrical to the first cavity. The sand core is disposed in the first cavity and the second cavity.

[0006] The faucet casting mold according to embodiments of the present invention has at least the following beneficial effects: Since the first flow channel connects the first main casting channel and the first inlet pipe casting channel, the width of the first flow channel gradually increases along the direction from the first main casting channel to the first inlet pipe casting channel. Similarly, the second flow channel connects the first main casting channel and the first outlet pipe casting channel, and the width of the second flow channel gradually increases along the direction from the first main casting channel to the first outlet pipe casting channel. Therefore, when molten copper is injected into the first main casting channel through the first casting port, the molten copper enters the first inlet pipe casting channel through the first flow channel. During the flow of the molten copper, the speed gradually slows down, and the molten copper diffuses into the first inlet pipe casting channel. Furthermore, the molten copper enters the first outlet pipe casting channel through the second flow channel. During the flow of the molten copper, the speed gradually slows down, and the molten copper diffuses into the first outlet pipe casting channel. The second mold unit has a second cavity symmetrical to the first cavity; therefore, the casting process of the second cavity is the same as described above. In summary, when molten copper is poured into the faucet casting mold, the copper flow rate slows down and the flow becomes more diffused, thus improving the faucet casting effect.

[0007] According to one embodiment of the present invention, the first mold unit is provided with a first venting structure, the first venting structure includes a first venting cavity and a plurality of first venting holes, the first venting cavity is connected to the first cavity, the first venting holes are arranged in the vertical direction and are connected to the first venting cavity, and the second mold unit is provided with a second venting structure symmetrical to the first venting structure.

[0035] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0036] As is well known, faucets are now mostly produced using casting methods, and faucet casting molds are indispensable in the casting process. Currently, when molten copper is poured into the faucet casting mold, the flow rate of the molten copper is too fast and the flow is uneven, resulting in poor faucet casting quality.

[0037] Therefore, one embodiment of the present invention provides a faucet casting mold 100, as detailed in the accompanying drawings. Figures 1 to 3 As shown.

[0038] Reference Figure 1 As shown, an embodiment of the present invention discloses a faucet casting mold 100, which includes a first mold unit 110, a second mold unit 120, and a sand core 130. The first mold unit 110 is provided with a first cavity 111. It should be noted that the first cavity 111 includes a first main casting channel 1111, a first inlet pipe casting channel 1112, and a first outlet pipe casting channel 1113. The first main casting channel 1111 is provided with a first casting port 1101, which communicates with the outside. Obviously, molten copper can be injected into the first main casting channel 1111 through the first casting port 1101. In addition, a plurality of first protrusions 1102 are provided at the edge of the first main casting channel 1111, and the plurality of first protrusions 1102 are spaced apart. It should be noted that the edges of the first protrusions 1102 are arc-shaped, and the plurality of first protrusions 1102 define a first flow channel 1103 and a second flow channel 1104. The first flow channel 1103 is defined by two adjacent first protrusions 1102, and the second flow channel 1104 is also defined by two adjacent first protrusions 1102.

[0039] Reference Figure 1As shown, the first flow channel 1103 connects the first main casting channel 1111 and the first water inlet casting channel 1112. This means that molten copper from the first main casting channel 1111 can enter the first water inlet casting channel 1112 through the first flow channel 1103. It should be noted that the width of the first flow channel 1103 gradually increases along the direction from the first main casting channel 1111 to the first water inlet casting channel 1112. Clearly, when molten copper flows from the first main casting channel 1111 to the first water inlet casting channel 1112 through the first flow channel 1103, the flow velocity of the molten copper gradually decreases due to the gradually increasing width of the first flow channel 1103, and it flows in a divergent manner, thereby improving the casting effect of the faucet's water inlet pipe.

[0040] Continue to refer to Figure 1 As shown, the second flow channel 1104 connects the first main casting channel 1111 and the first outlet casting channel 1113. This means that molten copper from the first main casting channel 1111 can enter the first outlet casting channel 1113 through the second flow channel 1104. It should be noted that the width of the second flow channel 1104 gradually increases along the direction from the first main casting channel 1111 to the first outlet casting channel 1113. Clearly, when molten copper flows from the first main casting channel 1111 to the first outlet casting channel 1113 through the second flow channel 1104, the flow velocity of the molten copper gradually decreases due to the gradually increasing width of the second flow channel 1104, and it flows in a divergent manner, thereby improving the casting effect of the faucet's outlet pipe.

[0041] Reference Figure 2 As shown, the second mold unit 120 is provided with a second cavity 121, which is symmetrical to the first cavity 111. It can be understood that the second cavity 121 includes a second main casting channel 1211, a second water inlet casting channel 1212, and a second water outlet casting channel 1213. It should be noted that the second main casting channel 1211 is symmetrically arranged with the first main casting channel 1111, the second water inlet casting channel 1212 is symmetrically arranged with the first water inlet casting channel 1112, and the second water outlet casting channel 1213 is symmetrically arranged with the first water outlet casting channel 1113. The second main casting channel 1211 is provided with a second pouring port 1201, which communicates with the outside. Obviously, molten copper can be injected into the second main casting channel 1211 through the second pouring port 1201. In addition, a plurality of second protrusions 1202 are provided at the edge of the second main casting channel 1211, and the plurality of second protrusions 1202 are spaced apart. It should be noted that the edges of the second protrusions 1202 are arc-shaped, and the plurality of second protrusions 1202 define the third flow channel 1203 and the fourth flow channel 1204. The third flow channel 1203 is defined by two adjacent second protrusions 1202, and the fourth flow channel 1204 is also defined by two adjacent second protrusions 1202.

[0042] Reference Figure 2 As shown, the third flow channel 1203 connects the second main casting channel 1211 and the second water inlet casting channel 1212. This means that molten copper from the second main casting channel 1211 can enter the second water inlet casting channel 1212 through the third flow channel 1203. It should be noted that the width of the third flow channel 1203 gradually increases along the direction from the second main casting channel 1211 to the second water inlet casting channel 1212. Clearly, when molten copper flows from the second main casting channel 1211 to the second water inlet casting channel 1212 through the third flow channel 1203, the flow velocity of the molten copper gradually decreases due to the gradually increasing width of the third flow channel 1203, and it flows in a divergent manner, thereby improving the casting effect of the faucet's water inlet pipe.

[0043] Continue to refer to Figure 2 As shown, the fourth flow channel 1204 connects the second main casting channel 1211 and the second outlet casting channel 1213. This means that molten copper from the second main casting channel 1211 can enter the second outlet casting channel 1213 through the fourth flow channel 1204. It should be noted that the width of the fourth flow channel 1204 gradually increases along the direction from the second main casting channel 1211 to the second outlet casting channel 1213. Clearly, when molten copper flows from the second main casting channel 1211 to the second outlet casting channel 1213 through the fourth flow channel 1204, the flow velocity of the molten copper gradually decreases due to the gradually increasing width of the fourth flow channel 1204, and it flows in a divergent manner, thereby improving the casting effect of the faucet's outlet pipe. In summary, when molten copper is injected into the faucet casting mold 100, the molten copper undergoes a process of slowing down its flow velocity and flowing in a divergent manner, thus improving the faucet casting effect.

[0044] Reference Figure 1 As shown, the sand core 130 is disposed in the first cavity 111 and the second cavity 121. It should be noted that the first mold unit 110 is provided with a first positioning groove 115 and a second positioning groove 116. The first positioning groove 115 communicates with the first water inlet casting channel 1112, and the second positioning groove 116 communicates with the first water outlet casting channel 1113. Furthermore, the first positioning groove 115 and the second positioning groove 116 are positioned and engaged with the sand core 130. (Refer to...) Figure 2As shown, it should also be noted that the second mold unit 120 is provided with a third positioning groove 125 and a fourth positioning groove 126. The third positioning groove 125 communicates with the second water inlet casting channel 1212, and the fourth positioning groove 126 communicates with the second water outlet casting channel 1213. Furthermore, the third positioning groove 125 and the fourth positioning groove 126 are positioned and fitted with the sand core 130. It should be noted that after the first mold unit 110 and the second mold unit 120 are closed, the first positioning groove 115 and the third positioning groove 125 actually combine to form a hole-like structure that positions and fits with the sand core 130, and the second positioning groove 116 and the fourth positioning groove 126 actually combine to form a hole-like structure that positions and fits with the sand core 130.

[0045] Reference Figure 3 As shown, in one embodiment of the present invention, a faucet casting mold 100 has a first mold unit 110 equipped with a first venting structure 112. The first venting structure 112 includes a first venting chamber 1121 and a plurality of first venting holes 1122. It should be noted that the first venting chamber 1121 communicates with the first mold cavity 111; the first venting holes 1122 are arranged vertically and communicate with the first venting chamber 1121. Obviously, during the casting of the faucet, as molten copper is injected, the gas in the first mold cavity 111 will be discharged sequentially from the first venting chamber 1121 and the plurality of first venting holes 1122. It can be understood that the above arrangement makes the gas discharge more stable. In one embodiment, the first venting chamber 1121 is arranged horizontally and is semi-circular in shape. By adopting the above scheme, after the gas enters the first exhaust chamber 1121, it takes a certain amount of time to fill the first exhaust chamber 1121 before the gas flows out from the multiple first exhaust holes 1122. This slows down the speed of the gas when it is discharged from the first exhaust holes 1122, making the exhaust more stable.

[0046] Reference Figure 2As shown, it should be noted that the second mold unit 120 is provided with a second venting structure 122. The second venting structure 122 includes a second venting chamber 1221 and a plurality of third venting holes 1222. The second venting chamber 1221 communicates with the second cavity 121; the third venting holes 1222 are arranged vertically and communicate with the second venting chamber 1221. It should be noted that the second venting chamber 1221 is symmetrically arranged with the first venting chamber 1121, and the plurality of third venting holes 1222 are symmetrically arranged with the plurality of first venting holes 1122. Obviously, during the casting of the faucet, as the molten copper is injected, the gas in the second cavity 121 will be discharged sequentially from the second venting chamber 1221 and the plurality of third venting holes 1222. It can be understood that the above arrangement makes the gas discharge more stable. In one embodiment, the second venting chamber 1221 is arranged horizontally and is semi-circular in shape. By adopting the above scheme, after the gas enters the second exhaust chamber 1221, it takes a certain amount of time to fill the second exhaust chamber 1221 before the gas flows out from multiple third exhaust holes 1222. This slows down the speed of the gas when it is discharged from the third exhaust holes 1222, making the exhaust more stable.

[0047] Reference Figure 3 As shown, in one embodiment of the present invention, a faucet casting mold 100 has a first mold unit 110 with a first groove 113, wherein the first groove 113 communicates with a first cavity 111. In one embodiment, the first groove 113 communicates with a first venting cavity 1121. Furthermore, the first groove 113 has a plurality of first venting grooves 1131, which are spaced apart horizontally. (Refer to...) Figure 2 As shown, the second mold unit 120 is provided with a first protrusion 123, which is symmetrically arranged with the first groove 113. It should be noted that the first protrusion 123 is provided with a second groove 1241231, which communicates with the second cavity 121. Simultaneously, the first protrusion 123 has a plurality of second venting grooves 1232 on the side facing the first mold unit 110, which are spaced apart horizontally. In one embodiment, the second groove 1241231 communicates with the second venting cavity 1221. It should be noted that the first protrusion 123 cooperates with the first groove 113, and the plurality of second venting grooves 1232 correspond one-to-one with the plurality of first venting grooves 1131 to form a plurality of second venting holes. It can be understood that through the above arrangement, gas can be diverted, making the venting during the faucet casting process more stable.

[0048] Reference Figure 3 As shown, in one embodiment, two first grooves 113 are provided, and the two first grooves 113 are spaced apart in the horizontal direction. (Refer to...) Figure 2As shown, in one embodiment, two first protrusions 123 are provided, and the two first protrusions 123 are symmetrically arranged with the two first grooves 113 respectively, and respectively cooperate with the two first grooves 113. It can be understood that by adopting the above solution, the stability of venting during the faucet casting process is further improved. It should be noted that the number of first grooves 113 is the same as the number of first protrusions 123. The number of first grooves 113 and the number of first protrusions 123 are not specifically limited here.

[0049] Reference Figure 3 As shown, in one embodiment, a second protrusion 114 is provided between the two first grooves 113. The second protrusion 114 is provided with a third groove 1141, wherein the third groove 1141 communicates between the two first grooves 113. In addition, a second groove 1241231 is provided between the two first protrusions 123, and the second protrusion 114 is positioned and engaged with the second groove 1241231. It can be understood that, through the above arrangement, the first mold unit 110 and the second mold unit 120 can be better positioned when they are closed. In addition, the third groove 1141 can also provide positioning support for the sand core 130.

[0050] Reference Figure 1 As shown, in one embodiment of the present invention, a faucet casting mold 100 has a first mold unit 110 equipped with a connecting post 117, which is located on the side of the first mold unit 110 facing the second mold unit 120. (Refer to...) Figure 2 As shown, the second mold unit 120 is provided with a connecting hole 127, which is located on the side of the second mold unit 120 facing the first mold unit 110. It should be noted that connecting posts 117 are inserted into the connecting holes 127 to achieve mold closing. In one embodiment, multiple connecting posts 117 and multiple connecting holes 127 are provided, with the multiple connecting posts 117 correspondingly inserted into the multiple connecting holes 127.

[0051] One embodiment of the present invention also provides a faucet casting device 1000, as detailed in the accompanying drawings. Figures 4 to 5As shown. The faucet casting apparatus 1000 includes a compressor 200, a crucible 300, a liquid inlet pipe 400, and a faucet casting mold 100 according to this embodiment of the invention. It should be noted that the compressor 200 is connected to the crucible 300 and can supply compressed air to the crucible 300. Furthermore, the liquid inlet pipe 400 connects the inner cavity of the crucible 300 and the first casting port 1101, and also connects the inner cavity of the crucible 300 and the second casting port 1201. In fact, the second casting port 1201 is symmetrically arranged with the first casting port 1101. It can be understood that the crucible 300 contains molten copper for casting. When the compressor 200 supplies compressed air to the crucible 300, the molten copper in the crucible 300 enters the faucet casting mold 100 from the liquid inlet pipe 400 under the action of air pressure. It should be noted that the molten copper in the crucible 300 enters the first mold cavity 111 and the second mold cavity 121 through the liquid inlet pipe 400 from the first casting port 1101 and the second casting port 1201 under the action of air pressure.

[0052] Reference Figure 4 As shown, it should be noted that the first mold unit 110 is provided with a first connecting rod, which is located on the side of the first mold unit 110 opposite to the second mold unit 120. The second mold unit 120 is provided with a second connecting rod 128, which is located on the side of the second mold unit 120 opposite to the first mold unit 110. Furthermore, the faucet casting device 1000 also includes a robotic arm, which is connected to the first connecting rod and the second connecting rod 128. It is understood that the robotic arm can manipulate the first connecting rod and the second connecting rod 128, thereby manipulating the movement of the faucet casting mold 100. Additionally, it can also control the closing and opening of the faucet casting mold 100. Through the above configuration, the casting efficiency of the faucet can be improved.

[0053] Reference Figure 4 As shown, in one embodiment, the crucible 300 is provided with a liquid filling hole 310. It should be noted that, under normal circumstances, the liquid filling hole 310 is closed. When the copper liquid in the crucible 300 is insufficient, the user can open the liquid filling hole 310 to add copper liquid to the crucible 300 to continue casting the faucet. In one embodiment, the faucet casting device 1000 also includes a surrounding plate 600, which is installed above the crucible 300 and encloses the faucet casting mold 100 inside. It should be noted that the surrounding plate 600 can provide protection in case of accidental spillage of copper liquid, preventing it from splashing onto the surrounding ground.

[0054] Reference Figure 4As shown, it should be noted that the faucet casting device 1000 also includes a support base 500. The compressor 200 and crucible 300 are mounted on the support base 500, which provides support for the compressor 200 and crucible 300. It should also be noted that multiple support columns 510 are provided below the support base 500 to better support the compressor 200 and crucible 300. (Refer to...) Figure 5 As shown, a placement groove 520 is provided above the support base 500, and the crucible 300 is installed in the placement groove 520. It can be understood that by adopting the above scheme, the crucible 300 can be installed more stably.
