Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically a combined PVC environmentally friendly water supply and drainage pipe mold. Background Technology

[0002] Modular PVC drainage pipes are a type of drainage pipe system composed of various different components. Modular PVC drainage pipes include PVC pipe bodies and connecting parts, among which the PVC pipe bodies need to be manufactured using molds.

[0003] Patent CN212498759U discloses a processing mold for producing municipal engineering drainage pipes. The mold includes a pipe body and rings at both ends of the pipe body. The rings have mounting holes for connecting to the drainage pipes distributed equidistantly around their circumference. The mold includes an upper mold part and a lower mold part that opens and closes with the upper mold part. When the upper mold part and the lower mold part are closed, they form a cavity. The lower mold part has a left mounting seat and a right mounting seat on its two sides, respectively. A first core that slides into the cavity is slidably mounted on the left mounting seat, and a second core that slides into the cavity and corresponds to the first core is slidably mounted on the right mounting seat. When the mold part is closed, the two ends of the cavity have annular cavities for injection molding into rings. The left mounting seat, the right mounting seat, and the left and right sides of the upper mold part all have sliding rods that can slide through the annular cavities for injection molding to form mounting holes, as well as driving components for driving the sliding rods to slide.

[0004] The prior art, such as the aforementioned patent, allows the finished product to be placed on the lower mold by driving the first and second mold cores away from the lower mold, and then the operator can take the finished product out of the lower mold. However, some mold cores are fixedly connected to the lower mold, and since the length of the mold core is equal to the length of the pipe, it is not easy for the operator to take the pipe out of the mold. Utility Model Content

[0005] The purpose of this invention is to provide a combined PVC environmentally friendly water supply and drainage pipe mold to solve the problem that the existing technology has the problem that the pipe product is not easy for the operator to remove when it is sleeved on the mold core.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a combined PVC environmentally friendly water supply and drainage pipe mold, comprising a base, a lower mold fixedly installed on the base, and an upper mold vertically slidably connected to the base, characterized in that the base is provided with a guide groove, the guide groove comprising a straight segment groove and an inclined segment groove connected in a continuous manner, a sliding column slidably connected to the guide groove, a side plate rotatably connected to the sliding column, a first mold core fixedly installed on the side plate, a second mold core fixedly installed on the lower mold, a sliding plate slidably connected to the base along the extension direction of the first mold core, a telescopic rod fixedly connected to the sliding plate, the inner rod of the telescopic rod being fixedly connected to the side plate, and a driving component for driving the sliding plate to slide on the base.

[0007] Furthermore, the base is provided with a sliding groove, and the sliding plate is slidably connected to the sliding groove.

[0008] Furthermore, the driving component includes a drive motor and a lead screw. The lead screw is rotatably connected to the base, the drive motor is fixedly mounted on the base, the output end of the drive motor is connected to the lead screw via transmission, and the lead screw is threadedly connected to the slide plate.

[0009] Furthermore, multiple columns are fixedly connected to the base, and the same top plate is fixedly connected to each column. A hydraulic cylinder is fixedly installed on the top plate, and the upper mold is slidably connected to each column. The telescopic rod of the hydraulic cylinder is fixedly connected to the upper mold.

[0010] Furthermore, a fixing plate is fixedly connected to one side of the lower mold, and the second mold core is fixedly mounted on the fixing plate.

[0011] Furthermore, the upper mold has a semi-cylindrical first cavity, and the lower mold has a semi-cylindrical second cavity. When the upper and lower molds are closed, the first cavity and the second cavity form a complete cylindrical cavity.

[0012] Furthermore, the first mold core is screwed onto the side plate, and the second mold core is screwed onto the lower mold.

[0013] Compared with the prior art, the present invention provides a combined PVC environmentally friendly water supply and drainage pipe mold. After the injection molding product is completed in the closed state of the upper and lower molds, and the drainage pipe is still between the upper and lower molds, the operator needs to first move the upper mold away from the base, and then drive the sliding plate to slide through the drive component. The sliding plate drives the telescopic rod and then drives the side plate to move along the guide groove, so that the side plate drives the first mold core to move. In this state, the pipe produced will have a hollow area, and the side of the lower mold near the hollow area is unobstructed, which makes it convenient for the operator to clamp the pipe wall of the drainage pipe and remove the drainage pipe from the lower mold.

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] Please see Figure 1-4This utility model provides a combined PVC environmentally friendly water supply and drainage pipe mold, including a base 1, a lower mold 2 fixedly installed on the base 1, and an upper mold 3 vertically slidably connected to the base 1. The upper mold 3 has a semi-cylindrical first cavity 31, and the lower mold 2 has a semi-cylindrical second cavity 23. When the upper mold 3 and the lower mold 2 are closed, the first cavity 31 and the second cavity 23 form a complete cylindrical cavity. Multiple columns 12 are fixedly connected to the base 1, and a top plate 121 is fixedly connected to each column 12. A hydraulic cylinder 13 is fixedly installed on the top plate 121. The upper mold 3 is slidably connected to each column 12, and the telescopic rod 61 of the hydraulic cylinder 13 is fixedly connected to the upper mold 3 (each column 12 has a slide rail, and the upper mold 3 is slidably connected to each column 12 via the slide rail). A guide groove 4 is provided on the base 1, and the guide groove 4 includes a connected straight section groove 41 and an inclined section groove 42. 2. A sliding column 5 is slidably connected to the guide groove 4, and a side plate 51 is rotatably connected to the sliding column 5. A first mold core 511 is fixedly installed on the side plate 51, and a second mold core 21 is fixedly installed on the lower mold 2. Specifically, a fixed plate 22 is fixedly connected to one side of the lower mold 2, and the second mold core 21 is fixedly installed on the fixed plate 22. A sliding plate 6 is slidably connected to the base 1 along the extension direction of the first mold core 511. Specifically, a sliding groove 11 is provided on the base 1, and the sliding plate 6 is slidably connected to the sliding groove 11. A telescopic rod 61 is fixedly connected to the sliding plate 6, and the inner rod of the telescopic rod 61 is fixedly connected to the side plate 51. A driving component 7 for driving the sliding plate 6 to slide is also provided on the base 1. Specifically, the driving component 7 includes a drive motor 71 and a lead screw 72. The lead screw 72 is rotatably connected to the base 1, and the drive motor 71 is fixedly installed on the base 1. The output end of the drive motor 71 is connected to the lead screw 72 for transmission, and the lead screw 72 is threadedly connected to the sliding plate 6.

[0023] Working principle: When the upper mold 3 and lower mold 2 are closed, the first cavity 31 of the upper mold 3 and the second cavity 23 of the lower mold 2 form a complete cylindrical cavity. The side plate 51 and the fixing plate 22 seal both ends of the cavity. Then, material is injected into the cylindrical cavity to form a channel (injection molding into the cavity is existing technology and will not be described in detail here). Then, the operator retracts the piston rod of the hydraulic cylinder 13 into the cylinder, causing the upper mold 3 to slide along the extension direction of the column 12 and thus disengage from the lower mold 2. After the upper mold 3 moves a certain distance, the first mold core 511 and the second mold core 21... If the pipe cannot be removed from within the conduit, the operator needs to activate the drive motor 71. The output shaft of the drive motor 71 rotates, driving the lead screw 72 to rotate. Since the lead screw 72 is threadedly connected to the slide plate 6 and the slide plate 6 is slidably connected to the base 1, the rotation of the lead screw 72 drives the slide plate 6 to slide on the slide groove 11. The sliding of the slide plate 6 causes the telescopic rod 61 to move horizontally. Since the inner rod of the telescopic rod 61 is fixedly connected, the horizontal movement of the telescopic rod 61 causes the side plate 51 to move horizontally, which in turn causes the first mold core 511 to move horizontally. The sliding column 5 at the bottom of the side plate 51 is in the guide groove 4. During the sliding process within the straight section groove 41, the length of the telescopic rod 61 remains unchanged. The sliding column 5 at the bottom of the side plate 51 enters the inclined section groove 42 of the guide groove 4. Because the side plate 51 is fixedly connected to the inner rod of the telescopic rod 61, the sliding column 5 rotates relative to the side plate 51. The orientation of the side plate 51 does not change. Since the side plate 51 gradually moves closer to the sliding plate 6, the inner rod of the telescopic rod 61 gradually moves closer to the sleeve rod, causing the length of the telescopic rod 61 to shorten. Consequently, the side plate 51 continues to drive the first mold core 511 to move horizontally. At this point, the end of the second cavity 23 of the lower mold 2 away from the fixed plate 22 is no longer obstructed, and the first mold core 511... Removing the part leaves an unattached blank section on the inner wall of the pipe, in addition to the section fitted with the second mold core 21. This allows the operator to easily clamp one end of the pipe's circumferential wall and pull it out. After removing the pipe, the drive motor 71 drives the lead screw 72 to rotate, causing the slide plate 6 to slide. This allows the side plate 51 to move the first mold core 511 back to its original position and continue to abut against the second mold core 21 (the diameters of the circles containing the end faces of the first mold core 511 and the second mold core 21 are the same). It is worth mentioning that the output shaft of the drive motor 71 can rotate clockwise or counterclockwise. A YPZ4508 model motor can be used here.

[0024] This utility model provides a combined PVC environmentally friendly water supply and drainage pipe mold. After the injection molding product is completed in the closed state of the upper mold 3 and the lower mold 2, and the drainage pipe is still between the upper mold 3 and the lower mold 2, the operator needs to first move the upper mold 3 away from the base 1, and then drive the sliding plate 6 to slide through the driving component 7, so that the sliding plate 6 drives the telescopic rod 61 and then drives the side plate 51 to move along the guide groove 4, so that the side plate 51 drives the first mold core 511 to move. In this state, the pipe will have a hollow area and the side of the lower mold 2 near the hollow area will be unobstructed, which makes it convenient for the operator to clamp the pipe wall of the drainage pipe and remove the drainage pipe from the lower mold 2.

[0025] The first mold core 511 is screwed onto the side plate 51, and the second mold core 21 is screwed onto the lower mold 2. The operator can remove the first mold core 511 and the second mold core 21 from the side plate 51 and the lower mold 2 respectively to replace them with new mold cores of different thicknesses, thus producing drainage pipes with different inner diameters.

[0026] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
