Description

Technical Field

[0001] This application relates to the field of water meter component processing equipment technology, and more specifically to a water meter cover mold. Background Technology

[0002] A water meter is a measuring instrument used to measure and record the volume of water flowing through a water supply pipe. The water meter includes a cover. Patent document (CN217032636U) discloses a water meter, as shown in the accompanying drawings of its specification. Figure 1 As can be seen from the image, the water meter includes a cover, which is injection molded.

[0003] There is a type of watch cover, such as Figure 8 and Figure 9 As shown, the device includes a bottom portion 901 and a vertical cylindrical portion 902. The bottom portion 901 is located at one end of the vertical cylindrical portion 902. The end of the vertical cylindrical portion 902 opposite to the bottom portion 901 has several hook portions 903. The bottom portion 901 has a central hole 9011, and the edge of the central hole 9011 has a first extension portion 904. The first extension portion 904 extends from the bottom portion 901 toward the end of the vertical cylindrical portion 902 with the hook portions 903. It should be noted that after the above-mentioned watch cover is injection molded, because the edge of the watch cover's central hole has the first extension portion 904 extending toward the hook portions 903, a traditional angled ejector core-pulling mechanism cannot be used. This is because the angled ejector core-pulling mechanism needs to move toward the center to disengage from the hook portions 903, and the presence of the first extension portion 904 would completely block the movement path of the angled ejector, causing interference with the hook portions 903 and making demolding difficult.

[0004] In addition, in the existing molds, the linear drive cylinder is stationary while one end of the telescopic rod extends out of the cylinder and moves. This makes the linear drive cylinder less stable during operation. Moreover, as the telescopic rod extends out of the cylinder, the length occupied by the linear drive cylinder gradually increases, making the overall size of the mold larger.

[0005] Therefore, there is a need for a water meter cover mold that is easy to demold, has better stability, and a more compact structure. Summary of the Invention

[0006] The main objective of this application is to provide a water meter cover mold for molding a cover. The cover includes a bottom portion and a vertical cylindrical portion.

The end of the bottom portion opposite to the vertical cylindrical portion has an annular protrusion. The water meter cover mold includes a mold assembly, multiple cores, a linear drive device, and a base. The mold assembly includes a moving module, a fixed module, and a rotating module. The moving module is movably mounted on the base and has an injection port and a molding cavity. The injection port communicates with the molding cavity. The fixed module includes a fixed cylinder, and each core is movably and vertically arranged in the fixed cylinder. The core is located above the molded cavity, and one end of each core extends into the molding cavity. The core has a contoured groove.

The fixed seat is fixedly connected to the moving module, and both ends of the fixed rod are fixedly connected to the fixed seat. The moving cylinder is slidably mounted on the fixed rod and is poweredly connected to the rotating ring. This application sets a rotating demolding mechanism, which drives the product to rotate through the rotation of the rotating ring, causing the hook part to rotate out of the contoured groove of the core, thereby avoiding interference with the first extension and achieving smooth demolding. In addition, this application improves the overall stability by using a linear drive device where the cylinder moves while the fixed rod remains stationary.

[0007] Another objective of this application is to provide a water meter cover mold, wherein the movable module includes a first template, a second template, and a third template, the second template being located between the first template and the third template, the second template including a template base, a sealing member, and an upper cover, the template base having a first through hole, the sealing member being placed within the first through hole, the sealing member having a through forming hole, the upper cover being placed at the end of the first through hole away from the third template, and the end of the upper cover near the fixed cylinder having a first annular notch and a first conical surface, the end of the fixed cylinder near the upper cover having a first annular groove.

It will also be understood that the terms “comprising” and / or “having” as used in this specification specify the presence of the described features, numbers, steps, operations, components, elements or combinations thereof, without excluding the presence or addition of one or more other features, numbers, steps, operations, components, elements or groups thereof.

[0022] Indicative water meter cover mold, for reference Figures 1 to 7 A water meter cover mold according to any preferred embodiment of the present invention is used to form such as Figure 8 and Figure 9 The meter cover shown includes a bottom part 901 and a vertical cylindrical part 902. The bottom part 901 is located at one end of the vertical cylindrical part 902. The end of the vertical cylindrical part 902 opposite to the bottom part 901 has a plurality of hook parts 903. The bottom part 901 has a central hole 9011, and the edge of the central hole 9011 has a first extension 904. The first extension 904 extends from the bottom part 901 toward the end of the vertical cylindrical part 902 with the hook parts 903. The end of the bottom part 901 opposite to the vertical cylindrical part 902 has an annular protrusion 905. The water meter cover mold includes a mold assembly 10, a plurality of cores 20, a linear drive device 30, and a base.

[0023] Specifically, such as Figures 1 to 4As shown, the mold assembly 10 includes a movable module 101, a fixed module 102, and a rotating module 103. The movable module 101 is movably mounted on the base and has an injection port 1011 and a molding cavity 1012. The injection port 1011 communicates with the molding cavity 1012. The fixed module 102 includes a fixed cylinder 1021, on which each core 20 can be vertically and vertically arranged. One end of each core 20 extends into the molding cavity 1012, and each core 20 has a contoured groove 201. The rotating module 103 includes a rotating ring 1031. The rotating ring 1031 is rotatably and vertically sleeved on the outside of the fixed cylinder 1021. The linear drive device 30 is fixedly installed on the moving module 101. The linear drive device 30 is poweredly connected to the rotating ring 1031. The linear drive device 30 includes a fixed base 301, a fixed rod 302, and a moving cylinder 303. The fixed base 301 is fixedly connected to the moving module 101. Both ends of the fixed rod 302 are fixedly connected to the fixed base 301. The moving cylinder 303 is slidably installed on the fixed rod 302. The moving cylinder 303 is poweredly connected to the rotating ring 1031.

[0024] It should be noted that the cover is formed by injecting fluid into the molding cavity 1012 through the injection port 1011 and allowing the fluid to solidify. It should also be pointed out that after the fluid flows into the molding cavity 1012, a portion of the fluid flows into the contour groove 201, thereby forming the hook portion 903. Furthermore, after the fluid injection solidifies to form the watch cover, in order to unload the watch cover, the moving module 101 moves away from the fixed module 102, and the watch cover also moves accordingly. That is, at this time, the hook portion 903 moves relative to the fixed module 102. When the hook portion 903 no longer coincides with the fixed module 102 in the radial direction, the linear drive device 30 is activated, and the rotating ring 1031 rotates circumferentially, driving the formed watch cover to rotate circumferentially synchronously. At this time, since the hook portion 903 is no longer blocked by the fixed module 102, the hook portion 903 can rotate circumferentially relative to the core 20, and the hook portion 903 disengages from the contour groove 201. When the hook portion 903 disengages from the contoured groove 201, the watch cover can move axially along the axial direction of the fixed module 102 and complete demolding and unmolding, thereby realizing the forming and unmolding of the watch cover. In addition, by fixing the fixed base 301 and the fixed rod 302, and allowing the moving cylinder 303 to slide relative to the fixed rod 302, the overall length of the linear drive device 30 is kept constant at the length of the space occupied by the fixed rod 302 and the fixed base 301. When fluid flows into one chamber of the moving cylinder 303 and fluid flows out of another chamber, the moving cylinder 303 slides along the fixed rod 302 in the corresponding direction. Compared with the prior art, it has the advantages of better stability and more compact structure.

[0025] More specifically, such as Figure 1 and Figure 2 As shown, the mobile module 101 includes a first template 1013, a second template 1014, and a third template 1015, wherein the second template 1014 is located between the first template 1013 and the third template 1015, as shown. Figure 2 and Figure 3As shown, the second template 1014 includes a template base 10141, a closure member 10142, and an upper cover 10143. The template base 10141 has a first through hole 101411. The closure member 10142 is placed inside the first through hole 101411 and has a through forming hole 101421. The upper cover 10143 is placed at the end of the first through hole 101411 away from the third template 1015, and the upper cover 10143 is close to the fixing cylinder. One end of the fixed cylinder 1021 has a first annular notch 101431 and a first conical surface 101432. The end of the fixed cylinder 1021 near the upper cover 10143 has a first annular groove 101433. The fixed cylinder 1021 also has a plurality of first sliding grooves 10211 arranged in a circular array. The core 20 is slidably disposed within each of the first sliding grooves 10211. When the second template 1014, the third template 1015, and the fixed module 102 sequentially abut against each other in the height direction, as... Figure 3 As shown, the end of the core 20 near the upper cover 10143 is spaced at a predetermined distance from the first conical surface 101432 to form a first channel 1016. The sidewalls of the fixing cylinder 1021 and the core 20 are spaced at a predetermined distance from the hole wall of the forming hole 101421 to form a second channel 1017. The first annular groove 101433, the first channel 1016, the first annular notch 101431, the second channel 1017 and the contoured groove 201 together form the forming cavity 1012.

[0026] It should be noted that when the fluid material flows into the molding cavity 1012, the fluid material filling the first annular groove 101433 forms the first extension 904. The obstruction of the fixed cylinder 1021 causes the fluid material to form the central hole 9011 after solidification. The fluid material filling the first annular notch 101431 forms the annular protrusion 905. The fluid material in the first channel 1016 solidifies to form the bottom part 901, and the fluid material in the second channel 1017 solidifies to form the vertical cylinder part 902.

[0027] Furthermore, such as Figure 6 As shown, the fixed cylinder 1021 has a cross-shaped flow groove 10212 and a flow hole 10213 on one end face near the closure member 10142. The flow hole 10213 is connected to the first annular groove 101433, and the center of the cross-shaped flow groove 10212 is connected to the injection port 1011.

[0028] It should be noted that the fluid material flows into the cross groove 10212 from the injection port 1011 and flows into the first annular groove 101433 along the flow hole 10213.

[0029] Furthermore, such as Figure 7 As shown, the closure 10142 also has a cooling channel 101422.

[0030] It should be noted that by setting the cooling channel 101422, during the injection molding process, the fluid flows through the cooling channel 101422 and carries away the heat transferred from the molding cavity 1012 to the closure 10142.

[0031] Furthermore, such as Figure 4 As shown, the rotating ring 1031 has a first meshing tooth portion 10311 on one side, the moving cylinder 303 has a rack portion 3031, and the rotating module 103 further includes a central rotating gear 1032. The central rotating gear 1032 is rotatably mounted on the third template 1015, and the central rotating gear 1032 meshes with the rack portion 3031 and the first meshing tooth portion 10311 respectively. Figure 3 and Figure 5 As shown, the rotating ring 1031 also has a second extension 10312, which extends into the second channel 1017.

[0032] It should be noted that when the fluid material fills the second channel 1017 and forms the vertical cylinder 902, the vertical cylinder 902 has a rotating groove 9021, and the second extension 10312 extends into the rotating groove 9021. When the moving cylinder 303 slides, the central gear 1032 rotates circumferentially and drives the rotating ring 1031 to rotate circumferentially. Then, when the hook 903 is misaligned with the fixed cylinder 1021 in the radial direction, the moving cylinder 303 rotates, and because the second extension 10312 extends into the rotating groove 9021, the cover rotates circumferentially as well. It should also be noted that during demolding, the first template 1013 and the second template 1014 first move away from the fixed module 102 and expose the molded cover. Then, the third template 1015 moves away from the fixed module 102. At this time, since the hook portion 903 extends into the contour groove 201, the cover moves away from the fixed module 102 as the third template 1015 moves. This achieves the offset arrangement of the hook portion 903 from the fixed cylinder 1021 in the radial direction. In addition, the movement of the first template 1013, the second template 1014 and the third template 1015 is all driven by an external linear drive cylinder.

[0033] Furthermore, such as Figure 4 As shown, the fixing base 301 includes a long strip 3011 and two bent portions 3012. The two ends of the long strip 3011 are bent at a predetermined angle away from the third template 1015 to form the bent portions 3012. The long strip 3011 and the two bent portions 3012 together form a U-shape. The fixing rod 302 is located between the two bent portions 3012, and the two ends of the fixing rod 302 are respectively connected to the two fixing rods 302. The moving cylinder 303 has a guide notch 3032 on the side near the third template 1015. The side of the long strip 3011 away from the third template 1015 extends into the guide notch 3032. The long strip 3011 is fixedly connected to the third template 1015. The side of the long strip 3011 away from the bent portions 3012 has the rack portion 3031.

[0034] It should be noted that by extending the elongated portion 3011 into the guide notch 3032, the stability of the moving cylinder 303 during movement is further improved.

[0035] Furthermore, such as Figure 3 As shown, the water meter cover mold also includes a top rod 40. The center of the fixed cylinder 1021 has a lifting hole 10214. The top rod 40 is lifted and lowered in the lifting hole 10214. One end of the lifting hole 10214 is connected to the cross flow groove 10212.

[0036] It should be noted that after the watch cover is injection molded, the top rod 40 is moved up and down, pushing the watch cover away from the fixed cylinder 1021.

[0037] Furthermore, such as Figure 3 As shown, the side of the fixing cylinder 1021 is a conical surface with a cone angle of 3° to 15°, preferably 10°, which makes it easier for the watch cover to detach from the fixing cylinder 1021 after injection molding.

[0038] In summary, the water meter cover mold described in the embodiments of this application is explained, which provides advantages such as easy demolding, better stability, and more compact structure for the water meter cover mold.
