What is parting lock?
Parting lock is also called nylon mold clamp, resin shutter, nylon mold lock, resin mold clamp,
nylon resin shutter, etc. It is a mold component that adjusts the friction between the template
and the nylon sleeve by locking the tapered bolts.
Parting lock function and characteristics:
1. Adjust the friction between the template and the resin by the inclined screw, and the mold can
be closed about 50,000 times for about 1/4 turn;
2. It is easy and simple to take off and unload the mold device;
3. This device can also be used on the workpiece with a small nozzle plate and hitting plate or the
second section to eject the small nozzle or slide;
4. For mold weight below 100KG, use 4 pieces of 12D, under 500KG, use 4 pieces of 16D, and
under 1000KG, use 4 pieces of 20D;
5. Colors: four kinds of color, white, yellow, orange, blue, blue one can withstand a high
temperature of 160 degrees.
The parting lock uses special nylon material, which has good wear resistance and heat resistance.
Although the heat resistance temperature of the nylon sleeve is 150 ° C, in actual use, it is

constantly subject to the locking stress of the tapered bolt The effect of this will lead to a
decrease in the durability of the nylon sleeve. Generally, the normal use temperature is below
80 ℃.
Material: nylon resin + high strength alloy steel
Tolerance: ± 0.002 ㎜
Material and hardness
Material SCM435 resin nylon
Hardness 33-38HRC
How to install the parting lock on the mold?
Parting lock installation:
The surface roughness of apex mirror processing can reach 0.1s or less and can carry out text
engraving processing, which is widely used in semiconductor packaging molds.
It can carry out a variety of post-processing such as surface chrome plating, tip lettering, etc.
These products have high hardness, good toughness, excellent wear resistance, and heat
resistance, and are more suitable for precision molds, which can significantly increase their
service life, especially the hot shape of precision molds has been effectively controlled.
After the surface treatment of this type of product, the surface of the product has higher
hardness, wear-resistance and corrosion resistance. The internal hardness is low and the
toughness is particularly good. It is suitable for molds in high-temperature operating
environments.
Installation method and precautions
• Embed the nylon sleeve to about 3mm of the movable mold template.
• Finish the inner surface roughness of the fixed template hole to 1.6-0.2. Round the R of the
template face insertion opening. If the C chamfer is processed, its durability will be reduced.
• Dimensional tolerance reference of the hole: H7 reaming, based on H7 reaming ~ +0.1.
• If special bushings are used, the above rounding R and polishing steps can be omitted.
• Adjust the required pulling force according to the tightening amount of the cone bolt.
Parting lock Installation warning: No need to use a lubricant. Otherwise, it will reduce friction and
reduce its original function.
Rough standard of parting locks usage:
Parting lock model usage quantity Mold weight
DGMF-PL10 4 sets under 100kg
DGMF-PL13 4 sets under 250kg
DGMF-PL16 4 sets over 250kg
DGMF-PL20 4 sets over 300kg
