Application of new hot runner flow regulating system technology

I. Traditional issues:

There are some problems in the traditional production mode of centrifugal vane, such as serious material waste inrunner, low qualified rate of products and poor dynamic balance of products.

· The use of pin gate cold runner to feedplastic produces more waste and serious waste of raw materials;

· The product from one of cavities after pressure retention is overweight, the product pass rate is low, and the product dynamic balance is between 0.4 and 0.5. Molten plastic into the diverting plate, due to processing error, diverting plate temperature difference and other factors, in the actual production will appear into the feeding imbalance.

II. Solution:

1. the throttle valve control shunt plate flow flat.

2. The compound motion structure of the cylinder, gear and gate sleeve controls the flow balance of the flow channel.

III. technical improvement effect:

1. Hot runner to cold runner one-point spoke type feeding, two cavities plastic feed balance, single cavity dynamic balance is high, the weight of a mold inlet 14g, compared with the three-plate mold reduce the runner waste about 50g, and through the cylinder - gear - gate sleeve composite motion structure to ensure automatic cutting gate. Compared with the traditional one-out-two structure, the product forming cycle is shortened by 20 seconds. Taking the production of 100,000 mold products with one set of mold as an example, the production time of 47 shifts will be reduced.

2. The dynamic balance is more stable, keep within 0.3, product qualified rate as high as 98%; The same use of 450T injection molding machine, save the customer injection molding machine resources;

3. Save therunner waste, with 1 set of mold production 100,000 products, can save 4.9T material. The new hot runner system can be used in the cross flow vane and other products whoseplastic balance is difficult to solve, which can greatly improve the output of vane products.

4. In 2018, it was used in 2 moulds of Gree. For large products such as axial flow blades, the flow of a single blade is unbalanced.

5. The new hot runner flow regulation system can realize the blade product by 1*4 cav or 1*8 cav mold.
