Embodiment 1

[0027] like figure 1 Shown, the manufacture method of the rubber core that a kind of auto parts of the present invention is used, manufacture method comprises the steps:

[0028] Step 1, the rubber material is sent into the internal mixer for mixing;

[0029] In step 2, the rubber compound after mixing is subjected to a quick inspection test;

[0030] Step 3, put the rubber material in step 2 into the feeding port of the extruder and extrude it with the steel wire rope at the same time to obtain a semi-finished rubber core;

[0031] Step 4, put the semi-finished rubber core of step 3 into a vulcanization tank for vulcanization;

[0032] Step 5, demoulding the vulcanized rubber core;

[0033] Step six, get the finished rubber core.

[0034] The internal mixer described in step 1 is a machine that is equipped with a pair of rotors of specific shape and rotates relatively, and intermittently masticates and kneads polymer materials in a closed state with adjustable temperature...

Embodiment 2

[0044] The manufacturing method comprises the steps of:

Abstract

The invention discloses a manufacturing method of a rubber mandrel for an automotive part. The manufacturing method comprises the following steps of: 1, feeding a rubber material into an internal mixer to be subjected to mixing; 2, carrying out a fast inspection test on the mixed rubber material; 3, putting the rubber material in the step 2 in a feeding opening of an extruder to be simultaneously extruded with a steel wire rope to obtain a semi-finished rubber mandrel; 4, vulcanizing the semi-finished rubber mandrel in the step 3; 5, carrying out demolding on the vulcanized rubber mandrel; and 6, obtaining the finished rubber mandrel. The manufacturing method provided by the invention is simple; the cost is low; the production efficiency is high; and the mandrel is stable in quality, good in high temperature resistance and long in service life, is resistant to ozone aging, and can be recycled repeatedly.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a method for manufacturing a rubber core used in auto parts. Background technique [0002] With the continuous development and growth of my country's automobile industry, the preliminary statistics of domestic automobile manufacturing in 2011 reached 20 million, ranking first in the world. In order to adapt to the market demand and meet the purchasing desires and requirements of the people, major OEMs have launched new models with novel styles, safety and comfort, moderate price, environmental protection and energy saving. At the same time, major OEMs have higher and higher requirements for suppliers. With supply capacity, stable product quality, advanced technology and equipment, timely supply, good service, and low price included in the supporting system, how to deal with the 5%-15% price reduction indicators of major OEMs every year? For suppliers, opportunities, pressures...
