Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a mold of a supercharger hose with a branch. Background Art

[0002] With the development of modern industry and the continuous increase in demand, fluid transportation systems play a vital role in various fields. In this process, booster hoses, as a key transportation tool, are gradually attracting people's attention due to their unique design and functionality, and are widely used in various industries. Compared with traditional hoses, booster hoses with branches can easily realize branch connections in pipeline systems, allowing fluids to flow to different destinations as needed. This branch design provides more possibilities for the flexibility and diversity of fluid transportation systems.

[0003] The booster hose molds with branches currently on the market use an integrated mold core. During production, this type of mold is installed into the mold core before the subsequent pipe hot pressing process. However, due to the integrated design of the mold core, it becomes very difficult to separate the pipe and the mold core. Improper operation may even lead to pipe damage, which not only affects production efficiency but also increases production costs.

[0004] Therefore, it is urgent to provide a mold for a supercharger hose with a branch to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the disadvantages of the prior art and provide a mold for a supercharger hose with a branch.

[0006] To solve the above technical problems, the present invention adopts a technical solution: providing a mold for a supercharger hose with a branch, comprising a first module and two second modules, wherein an upper mold core is installed inside the first module, a lower mold core is installed between the two second modules, and the first module and the second module are rotatably connected by a plurality of fixing screws;

[0007] A main mold core is installed between the upper mold core and the lower mold core, and one side of the main mold core is rotatably connected to two detachable round blocks, and the outer walls of the two detachable round blocks are each provided with a disassembly hole, and the outer wall of the main mold core is attached to the first semi-finished film;

[0008] Two split molds are installed on the outer wall of the lower mold core. A plurality of fastening screws are rotatably connected between the two split molds. Split mold cores are installed inside the two split molds. The outer wall of the split mold core is attached to the second semi-finished film.

[0009] The utility model is further configured as follows: the first module and the second module are symmetrical structures.

[0010] Through the above technical solution, the symmetrical structure makes the device as a whole present a certain aesthetic appearance, and the shape of the produced hose is also relatively round, meeting production requirements.

[0011] The present invention is further configured such that: the second module adopts a block structure.

[0012] Through the above technical solution, the block-type module can be manufactured relatively easily because it can be divided into smaller parts for processing, which makes the processing of each module part simpler and can use simpler processes and equipment. For products with complex structures or internal channels, the block-type module can more easily realize the manufacturing and demolding operations of the mold because the module can be divided into multiple parts to adapt to complex shapes.

[0013] The utility model is further configured as follows: the detachable round block is connected to the main mold core by using threads.

[0014] Through the above technical solution, after completing the pressure-holding vulcanization step, the detachable round block can be easily removed from the main mold core by simply rotating the detachable round block, and then the main mold core can be taken out from the inside of the pipe. The operation is very simple and quick.

[0015] The utility model is further configured as follows: an outer wall of the main mold core is provided with an installation opening corresponding to the split mold core, and a connecting piece is installed between the two.

[0016] Through the above technical solution, the connecting piece is designed into a special snap-on structure. When connection is required, it is only necessary to connect the main mold core and the sub-mold core through the connecting piece, and then put the corresponding mold on the corresponding mold core to start the pressure-maintaining vulcanization process of the pipeline. When separation is required, it is only necessary to stir the connecting piece to separate the sub-mold core from the main mold core.

[0017] The utility model is further configured such that: the first semi-finished film and the second semi-finished film are both made of EPDM rubber.

[0018] Through the above technical solution, EPDM rubber has good elasticity and flexibility, and can maintain its elasticity and softness in a wide temperature range, which enables the film to maintain good sealing performance under different temperature conditions. The film made of EPDM rubber has the advantages of good weather resistance, strong chemical corrosion resistance, good elasticity and flexibility, excellent electrical insulation performance, good recyclability and environmental protection, excellent watertightness, etc., and is suitable for various industrial and commercial applications.

[0019] The utility model is further configured as follows: the split mold adopts a structure with a small port and a large root.

[0020] Through the above technical solution, the structure can increase the flow rate of condensed water in winter and prevent condensed water from condensing. The structure with a small port and a large root can effectively increase the flow rate of condensed water in the pipe. Due to the small port, the condensed water will encounter higher resistance when passing through the pipe, and the larger root can provide sufficient space for the water to flow smoothly. In this way, the residence time of condensed water in the pipe is reduced and the flow rate is increased, which is conducive to the rapid discharge of condensed water. Fast-flowing condensed water is not easy to condense in the pipe. By increasing the flow rate, the residence time of condensed water in the pipe can be reduced, thereby reducing the possibility of condensed water condensation, especially in winter when the ambient temperature is low and condensed water is easy to condense into ice. The use of this structure can effectively prevent the occurrence of freezing problems.

[0021] The beneficial effects of the utility model are as follows:

[0022] 1. The utility model designs the mold and the mold core into a split structure. When the hose needs to be pressure-maintained and vulcanized, it is only necessary to splice the mold and the mold core together according to the operating steps. After completing the pressure-maintained and vulcanized steps of the hose, it is only necessary to remove the mold and the mold core from the hose according to the corresponding steps. The overall installation and disassembly become very simple and quick, thereby improving the production efficiency of the hose.

[0023] 2. The utility model designs a tee pipe with a small port and a large root. The structure with a small port and a large root can effectively increase the flow rate of condensed water in the pipe. Due to the small port, the condensed water will encounter higher resistance when passing through the pipe, and the larger root can provide sufficient space for the water to pass smoothly. In this way, the residence time of the condensed water in the pipe is reduced and the flow rate is increased, which is conducive to the rapid discharge of the condensed water. The fast-flowing condensed water is not easy to condense in the pipe, which can effectively prevent the occurrence of freezing problems. BRIEF DESCRIPTION OF THE DRAWINGS
