AI Technical Summary
During the rotomolding process, the connection between the embedded insert and the rotomolding parts is not tight enough, resulting in liquid leakage in the tanks such as the fuel tank after installation.
A leak-proof embedded insert is designed, including an insert body and a sealing ring. A sealing groove and anti-detachment block are provided on the insert body. The sealing ring is a heat-resistant material, which has high elasticity and can be cooled on the rotary molded parts. Maintain tight connections during shrinkage and improve the anti-torsion performance of the insert through anti-torsion grooves and threaded through holes.
It effectively prevents liquid leakage, ensures the sealing effect of the rotomolded parts during cooling, and improves the connection stability between the insert and the rotomolded parts.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rotational molding machines, in particular to a leak-proof embedded insert. Background Art
[0002] Moulds are various moulds and tools used in industrial production to obtain the required products by methods such as rotational moulding, blow moulding, extrusion, die casting or forging, smelting, and stamping. In short, moulds are tools used to make moulded objects. This tool is composed of various parts, and different moulds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the moulded material. It is known as the "mother of industry".
[0003] In the process of producing roto-molded parts such as fuel tanks, in order to install the fuel tank on the frame or connect it to the engine, etc., it is necessary to embed inserts so that the fuel tank can be installed on the frame or connected to the pipeline. However, after the roto-molding is completed, the roto-molded parts wrapped around the embedded inserts gradually cool down, resulting in shrinkage, resulting in the connection between the embedded inserts and the roto-molded parts not being tight enough, which may cause leakage in the box. Utility Model Content
[0004] The main purpose of the utility model is to provide a leak-proof pre-embedded insert to solve the above technical problems and ensure the leak-proof effect.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A leakproof embedded insert comprises an insert body and a sealing ring, wherein the insert body is provided with a sealing groove, the sealing groove is annularly arranged on the insert body, and the sealing ring is sleeved on the insert body and placed in the sealing groove.
[0007] As a preferred technical solution, the cross section of the sealing groove is arc-shaped.
[0008] As a preferred technical solution, an anti-slipping protrusion is provided on the insert body, and the anti-slipping protrusion is fixedly arranged on the outer surface of the insert body.
[0009] As a preferred technical solution, the anti-slipping protrusion may be a cuboid or a regular hexagon.
[0010] As a preferred technical solution, the insert body is further provided with an anti-twist groove, and the anti-twist groove is arranged in an orderly manner between the anti-slip protrusion and the insert body.
[0011] As a preferred technical solution, the cross-section of the anti-twist groove is circular or rectangular.
[0012] As a preferred technical solution, a threaded through hole is provided on the insert body.
[0013] The beneficial effect of the utility model is that the above-mentioned leak-proof embedded insert is provided with a sealing ring on the insert body, the sealing ring is made of heat-resistant material, has high elasticity, and will not melt during rotational molding production. During the cooling and shrinkage process of the rotational molding part, the sealing ring can maintain a tight connection with the insert body and the rotational molding part, thereby ensuring the leak-proof effect. BRIEF DESCRIPTION OF THE DRAWINGS
[0014] Figure 1 This is a schematic diagram of the structure of the leak-proof embedded insert involved in the utility model;
[0015] Figure 2 It is a cross-sectional view of the leak-proof embedded insert involved in the utility model. DETAILED DESCRIPTION
[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0017] Please combine Figure 1 and Figure 2 As shown, a leak-proof embedded insert includes an insert body 1 and a sealing ring 2. A sealing groove 11 is provided on the insert body 1. The sealing groove 11 is annularly arranged on the insert body 1. The sealing ring 2 is sleeved on the insert body 1 and placed in the sealing groove 11. The sealing ring 2 is made of heat-resistant material and has high elasticity. It will not melt during rotational molding production. During the cooling and shrinkage of the rotational molding part, the sealing ring 2 can maintain a tight connection with the insert body 1 and the rotational molding part, thereby ensuring the leak-proof effect.
[0018] Specifically, the cross section of the sealing groove 11 is in an arc shape, which matches the outer surface of the sealing ring 2 and can increase the contact area with the sealing ring 2, thereby improving the sealing performance.
[0019] Specifically, the insert body 1 is provided with an anti-slipping protrusion 12, which is fixedly arranged on the outer surface of the insert body 1, so that the insert body 1 and the roto-molded part can be tightly connected after roto-molding. The anti-slipping protrusion 12 can be a rectangular parallelepiped or a regular hexagon, thereby increasing the anti-twist performance of the insert on the roto-molded part, and avoiding the situation that the roto-molded part cannot be fixed or the insert and the roto-molded part cannot be tightly connected when the insert is twisted when the insert is threadedly connected to the component during use. The insert body 1 is also provided with an anti-twist groove 13, which is orderly arranged on the end face of the anti-slipping protrusion 12 and is located between the anti-slipping protrusion 12 and the insert body 13. The cross-section of the anti-twist groove is circular or rectangular, which further improves the anti-twist performance of the insert body 1.
[0020] Specifically, the insert body 1 is provided with a threaded through hole 14 for connecting the insert with an external component.
[0021] The above-described embodiments are only preferred examples of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structures, features and principles described in the patent application scope of the present invention should be included in the scope of the patent application of the present invention.
