Abstract

The invention discloses a connector and a manufacturing method thereof. The method mainly comprises the following steps of: adding dried and proportioned raw materials into a heated injection molding machine; and achieving the best injection molding process by setting injection pressure, speed, injection time and injection volume of different sections of the injection molding machine and meanwhile setting final holding pressure and holding speed to obtain a final acceptable product. According to the invention, the physical performance defects of high probability of drag mark, fracture, poor toughness, low strength and the like of the product during molding of the injection molded connector are overcome; meanwhile, the injection molding process is stable; the obtained product is stable in quality; the production efficiency is increased; and the production cost is reduced.

Example Embodiment

[0017] Example 1: Connector, its constituent materials include composition A and composition B, said composition A: 645 parts of nylon PA and 45 parts of nylon PA6+30% GF; composition B: 45 parts of glass fiber, synthetic fiber 20 parts, 5 parts of magnesium oxide, 5 parts of methyl methacrylate, 15 parts of polyethylene resin, 3 parts of silane coupling agent, 5 parts of polytetrafluoroethylene, 5 parts of attapulgite, 5 parts of straw ash, gypsum 5 parts of powder and 2 parts of bentonite.
[0018] The manufacturing method of the connector includes the following steps:
[0019] (1) After mixing nylon PA6 and nylon PA6+30% GF raw materials, carry out drying treatment, the drying temperature is 100-120℃, the drying time is 4-6 hours, mix evenly, add to the dryer, at 140-160℃ Dry under 24-28h;
[0020] (2) Weigh each raw material in parts by weight of the composition B raw material, and dry it. The drying temperature is 120-150°C, the drying time is 3-5 hours, and the mixture is evenly mixed. Add to the dryer at 140-160°C. Drying 24-28h;
[0021] (3) Add the dried two sets of raw materials to the injection molding machine;
[0022] (4) Set the temperature of the heating section of the injection molding machine: the first section 260±5℃, the second section 255±5℃, the third section 250±5℃, the fourth section 245±5℃, the fifth section 240±5℃ ;
[0023] (5) Molding process parameters of injection section:
[0024] a. The first stage adopts 45-55Mpa medium pressure, 35-45m/s low speed injection, the injection time is 1.0-1.5 seconds, and the injection volume is 78-80% of the product;
[0025] b. The second stage uses a medium pressure of 30-40Mpa and a low-speed injection of 45-55m/s. The injection time is 0.5-1.0 seconds, and the injection volume is 100% of the product nozzle;
[0026] (6) Forming and demoulding.

[0028] The manufacturing method of the connector includes the following steps:
[0029] (1) After mixing nylon PA6 and nylon PA6+30% GF raw materials, carry out drying treatment, the drying temperature is 100-120℃, the drying time is 4-6 hours, mix evenly, add to the dryer, at 140-160℃ Dry under 24-28h;
[0030] (2) Weigh each raw material in parts by weight of the composition B raw material, and dry it. The drying temperature is 120-150°C, the drying time is 3-5 hours, and the mixture is evenly mixed. Add to the dryer at 140-160°C. Drying 24-28h;
[0031] (3) Add the dried two sets of raw materials to the injection molding machine;
[0032] (4) Set the temperature of the heating section of the injection molding machine: the first section 260±5℃, the second section 255±5℃, the third section 250±5℃, the fourth section 245±5℃, the fifth section 240±5℃ ;
[0033] (5) Molding process parameters of injection section:
[0034] a. The first stage adopts 45-55Mpa medium pressure, 35-45m/s low speed injection, the injection time is 1.0-1.5 seconds, and the injection volume is 78-80% of the product;
[0035] b. The second stage uses a medium pressure of 30-40Mpa and a low-speed injection of 45-55m/s. The injection time is 0.5-1.0 seconds, and the injection volume is 100% of the product nozzle;
