Description

Technical Field

[0001] The utility model relates to the technical field of rubber hose production molds, and specifically relates to a leak-proof rubber multi-way pipe mold. Background Art

[0002] During the production of multi-way hoses, due to the multi-way characteristics of the pipeline, the pipeline mold generally consists of two parts: the main pipe mold core and the side-way mold core. The main pipe mold core is shaped to match the direction of the hose main pipe. The main pipe mold core is provided with a mounting hole, and the side-way mold core is installed in the mounting hole. The number of side-way mold cores can be adjusted according to actual conditions.

[0003] During production, the main mold core and the side-through mold core are assembled together, and the side-through mold core is inserted into the mounting hole. When removing the mold, the side-through mold core is removed first, and then the main mold core. When the main mold core is pulled out of the molded hose, the sharp edges produced during the machining of the mounting hole will cut the inner wall of the hose, causing internal damage to the hose. In order to avoid cutting the inner wall of the hose, the edges of the mounting hole are usually rounded after machining, so that the edges of the mounting hole form rounded corners to avoid cutting. However, during hose production, the glue will flow into the rounded corners. Considering that in actual production, in order to facilitate the installation of the side-through mold core, the fitting between the mounting hole and the side-through mold core is mostly a clearance fit. This will lead to glue flow at the outer edge of the mounting hole, and the product quality cannot meet the standards. At the same time, it will increase the amount of glue used and increase production costs. Therefore, it is necessary to improve and optimize the existing technology. Utility Model Content

[0004] The utility model provides a multi-channel pipe mold that prevents glue from leaking, which solves the problem of glue flow caused by the rounded corners left at the location where the side channel mold cores are installed on the main mold core in the related art.

For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0043] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0044] Example 1, refer to Figures 1 to 3 , which is the first embodiment of the present utility model, proposes a leak-proof multi-way pipe mold.

[0045] In this embodiment, the multi-channel tube mold includes a main channel mold core 1, a side channel mold core 2, and a sleeve 3; the sleeve 3 is annular in shape; when in use, the sleeve 3 is entirely mounted on the side channel mold core 2, the positioning block on the side channel mold core 2 is aligned with the positioning groove, and the positioning block is snapped into the positioning groove, and the accuracy of the orientation of the side channel mold core 2 is ensured by the positioning block and the positioning groove; then the sleeve 3 is pressed toward the main channel mold core 1 until the sleeve 3 and the main channel mold core 1 are in squeeze contact, at which point the sleeve 3 completely covers the exposed portion of the mounting hole, and the maximum area of the sleeve 3 when spread out is larger than the cross-sectional area of the side channel mold core 2; the sleeve 3 protects the mounting hole, preventing the glue from flowing into the mounting hole along the rounded corners of the mounting hole to form glue flow, thereby improving the consistency of product quality. The sleeve 3 is made of elastically deformable material as a whole. When removing the mold, the side-through mold core 2 is pulled out in the direction away from the main mold core 1. The outer surface of the sleeve 3 is squeezed by the inner wall of the hose, deformed and moved toward the center as a whole. The sleeve 3 follows the side-through mold core 2 and is pulled out along the hose.

[0046] Example 2, refer to Figures 1 to 3 This is the second embodiment of the present invention. Based on the first embodiment, this embodiment further refines the structure of the sliding sleeve 13. The sleeve 3 includes a plurality of circumferentially distributed protective members 5. The protective members 5 are rotatably mounted on the side-through mold core 2. During use, the side-through mold core 2 is installed in the mounting hole. The protective members 5 are circumferentially distributed around the side-through mold core 2 and cover the mounting hole. When the side-through mold core 2 is removed, as the side-through mold core 2 moves away from the main mold core 1 along the inner wall of the hose, the protective members 5 are squeezed by the inner wall of the hose and rotate toward the side-through mold core 2 until the protective members 5 enter the receiving annular groove 4, thereby preventing extrusion friction between the inner wall of the hose and the protective members 5. This extends the service life of the sleeve 3.

[0047] Example 3, refer to Figures 1 to 3, which is the third embodiment of the present invention. On the basis of embodiment 2, this embodiment further adds an articulated seat 6 and a limit member 7; further adds a spring 8; when in use, the spring 8 is in a compressed state, and the accumulated elastic force of the spring 8 acts on the articulated seat 6 and the guard 5 in turn, ensuring that the guard 5 is tightly fitted with the outer surface of the main mold core 1 to avoid problems such as glue flow and glue leakage; when removing the side-through mold core 2, the side-through mold core 2 is pulled out along the inner wall of the hose in the direction away from the main mold core 1. Under the squeezing of the inner wall of the hose, the guard 5 rotates toward the side-through mold core 2, and at the same time, the guard 5 slides with the articulated seat 6 toward the main mold core 1; the spring 8 releases the accumulated elastic force to assist the sliding of the articulated seat 6, and at the same time, with the help of the limiting effect of the limit member 7, the articulated seat 6 is prevented from sliding too much and separating from the side-through mold core 2, causing the mold to disintegrate. When in use, the guard 5 pushes the hinge seat 16 to compress the spring 18 by means of the squeezing force between the guard 5 and the main mold core 1, thereby improving the tightness of the guard 5. The solution described in this embodiment is suitable for a guard 3 made of a relatively hard material.

[0048] Example 4, refer to Figures 1 to 4 , which is the fourth embodiment of the present utility model. On the basis of the second embodiment, this embodiment further adds an articulated seat 2 9, an articulated seat 3 10, a spring 2 11, a slide bar 12 and a sleeve 13. When in use, the guard 5 is squeezed by the inner wall of the hose and gradually rotates toward the side through-mold core 2. At this time, the guard 5 drives the articulated seat 2 9 and the slide bar 12 to slide synchronously. The articulated seat 2 9 squeezes the spring 2 11, and the spring 2 11 contracts under the force and accumulates elastic force. The spring 2 11 is sleeved on the outside of the sleeve 13. With the help of the sliding connection and guiding effect of the slide bar 12 and the sleeve 13, the spring 2 11 is prevented from lateral twisting deformation when deformed, resulting in failure of the spring 2 11. On the contrary, when the guard 5 is covered and installed, the spring 2 11 can help the guard 5 to spread outward, thereby preventing the guard 5 from being stuck in the receiving ring groove 4, resulting in failure of the guard 5.

[0049] Example 5, refer to Figures 1 to 3, which is the fifth embodiment of the present utility model. On the basis of the second embodiment, this embodiment further adds a push rod 14, an inner support member 15, an inner support head 16 and a rotating shaft 17; when in use, when the side through mold core 2 is installed to the mounting hole, the protective member 5 is spread on the main core mold and covers the outer edge of the mounting hole for protection; then an external force is applied to pull the push rod 14 to slide away from the main core mold, and the push rod 14 drives the inner support member 15 and the inner support head 16 to slide synchronously. In this embodiment, the number of rotating shafts 17 is preferably two, one on each side of the inner support member 15, and the one closer to the main mold core 1 is defined as axis A, and the one farther away from the main mold core 1 is defined as axis B; when the push rod 14 is away from the main mold core 1, the inner support member 15 is in rolling and extrusion contact with axis B. With the help of the extrusion of axis B, the inner support member 15 rotates toward the direction close to the guard member 5 until the inner support head 16 contacts the inner surface of the guard member 5. The arc surface of the inner support head 16 can avoid obvious indentations between the inner support head 16 and the guard member 5, and achieve smooth extrusion contact; with the support effect of the inner support member 15, the guard member 5 is prevented from collapsing toward the side mold core 2; the covering and protective effect of the guard member 5 is improved, and the consistency of the product is improved.

[0050] Conversely, when removing the side-through mold core 2, the push rod 14 is driven to slide toward the main mold core 1. The push rod 14 causes the inner support 15 and the inner support head 16 to slide synchronously. The other side of the inner support 15 is in rolling and extrusion contact with the axis A. With the help of the limiting and extrusion of the axis A, the inner support 15 and the inner support head 16 gradually move away from the guard 5 and gradually approach the side-through mold core 2, completing the storage operation. This facilitates the removal of the side-through mold core 2.

[0051] Example 6, refer to Figures 1 to 3 , which is the sixth embodiment of the present utility model. On the basis of the second embodiment, this embodiment further adds mutually cooperating clamping blocks 18 and clamping grooves 19. In this embodiment, the number of the guards 5 is preferably four. Looking along the circumferential direction, they are part one, part two, part three, and part four, wherein part one and part three are symmetrically distributed and defined as one group, and part two and part four are symmetrically distributed and defined as two groups. The clamping blocks 18 or clamping grooves 19 can only be distributed in one group, and the corresponding clamping grooves 19 or clamping blocks 18 are distributed in the two groups. With the help of the clamping fit between the clamping blocks 18 and the clamping grooves 19, the support effect between the guards 5 is provided. At the same time, when the side-through mold core 2 is removed, with the help of the stepped fit of the clamping blocks 18 and the clamping grooves 19, it is convenient to store the guards 5 in the storage ring groove 4.
