鹰潭The top ten differences between large and fine water die frames

1, the large nozzle is the mold that the front mold is not separated separately, also known as the second plate mold guide column formal assembly, and the fine nozzle is the fixed mold has a separate parting, that is, the mold is not only divided once (at least twice).

2, generally speaking, the large nozzle is more or less the water nozzle on the top of the product after stripping, and the fine nozzle is just the opposite!

3, the large water mouth front mold is A plate fixed fine water mouth has simplified and standard water mouth out in the front mold.

4, the fine water mouth than the large water mouth more than one water mouth material push plate.

5, large water mouth: need to be removed by manual or other means after the water mouth. A nozzle that does not need to be removed by manual or other means after ejecting the product from the flow path.

6, simply put: the big nozzle is two plate mold, the small nozzle is three plate mold, and the two are only short of a scraper.

7, the difference between the size of the water mouth is the difference between the two plates and the three plates, the small water mouth is also called the three plate die, the glue feeding method, the middle of a fast stripper plate, the feed head and the product are separated and come out from the nozzle when the glue is fed and divided, so that the material is automatically separated. The three-plate die is more than the two-plate die with resin or mechanical opener, small rod, large rod (the mold can not be designed when the mold is small) stripping with pulling nails, etc. The first two mainly play the role of controlling the opening sequence, the role of the big rod to protect the role of the small rod, the pulling nail is installed on the fixed plate of the mother die, and pulls the material head on the stripper plate.

8, the large nozzle generally needs the nozzle thimble, and the fine nozzle needs the drawing needle. The fine water nozzle is directly into the water, and the product does not need to be processed after taking out; The large nozzle is generally big mouth straight into, and the product is cut after taking out the nozzle. The large water mouth is also divided into sides and bottom straight into.

9, fine water mouth three boards, there are also special 2 boards! Feed port, large at the top and small at the bottom, 0.6-1.2MM. Load the drawing bar on the mold, pull out the material head in the middle of the upper mold 3 plate by hand! Generally used with products with high surface requirements, shells, caps, gears, etc.!

Large spouts are straight feed, latent, and other types. Direct feed is also small under the big, with large products, 1 out of 1 direct feed, such as large box, turnover box, can be the shell of the trademark! Large water mouth mold, pull rod load mold, and top dry together!

10, the small water mouth can be injected from any point of the cavity, while the large water mouth mostly enters the water from the side of the cavity.
