Embodiment

[0017] The present invention provides an injection molding mount, in which a thermoplastic elastomer 3, a metal outer liner 1 and a metal inner liner 2 are molded into such figure 1 In the injection molded body shown, the thermoplastic elastomer 3 is located between the metal outer lining pipe 1 and the metal inner lining pipe 2, and is connected to the metal outer lining pipe 1 and the metal inner lining pipe 2 respectively.

[0018] Another example figure 2 As shown, the metal inner tube 4 is pressed into the metal inner tube 2 so that the metal inner tube 4 and the metal inner tube 2 are in an interference fit.

[0019] Wherein, the structure of the metal outer lining pipe 1 and the metal inner lining pipe 2 is as follows: image 3 and Figure 4 As shown, through holes 5 are evenly distributed on its surface respectively, and the number of through holes 5 can be between 10-50. In this embodiment, the number is 30, and the diameter of through holes 5 is between 2-5mm. An...

Abstract

The invention relates to an injection molding suspension, which is characterized in that: a thermoplastic elastomer, a metal outer liner tube and a metal inner liner tube are subjected to injection molding to form an injection molding body; and a metal inner tube is pressed into the metal inner liner tube to ensure interference fit between the metal inner tube and the metal inner liner tube, wherein the thermoplastic elastomer is positioned between the metal outer liner tube and the metal inner liner tube and is respectively connected with the metal outer liner tube and the metal inner liner tube; and through holes are uniformly distributed on the surfaces of the metal outer liner tube and the metal inner liner tube. By injection-molding the thermoplastic elastomer, the optimized suspension structure solves the problem of bonding TPV and metal pieces, the TPV replaces rubber, and the pollution of waste gas, waste water and dust to the environment in the suspension manufacturing process is reduced.

Description

technical field [0001] The invention relates to a suspension. Background technique [0002] The suspension is used to reduce and control the transmission of engine vibration and play a supporting role. It is a kind of automotive powertrain. In the current automobile industry, the widely used mounts are divided into traditional pure rubber mounts and hydraulic mounts with better dynamic and static performance. Pure rubber mounts generally consist of rubber bushings and brackets. [0003] However, waste gas, waste water and dust will be generated during the manufacturing process of rubber products, which will cause serious pollution to the environment. [0004] Exhaust gas mainly comes from organic waste gas produced in the rubber mixing process; organic waste gas in the process of dipping and drying fiber fabrics; organic waste gas produced in the calendering process; organic waste gas produced in the vulcanization process; resins, solvents and other volatile organic compou...
