Demoulding Way for Crate Moulds

There are two common demoulding ways of crate mould, one is latch locking system, another one is hydraulic cylinder system.

Below is short analysis of these two demoulding systems.

For latch locking system, when mould opens, the latch lock pulls the slides to demould, which lead to short cycle time, high efficiency, so lots of customers prefer such system. Howere, compare with hydraulic cylinder system, latch locking system has short mould life. So Sino pay high attention in lengthening the mould life of latch locking system, and has accumulated rich experience. We make inserts between latch lock and slides, if the insert was broken, it is easy to make and change. Usually, we adopt high hardness and wear-resisting steel to make inserts, and send extra inserts to customer. Latch locking system has short cycle time, so the crash pressure on parting surface is large, so we add buffer gasket or spring under stripper and slides to reduce the crash pressure.

If customer want to make thin-wall crate mould, we suggest adopt H13 or DIN1.2344 steel for core and cavity since thin-wall crate has strict required on steel hardness. The thickness of thin-wall crate is less than 1mm, when injection, the injection pressure is very large, and the clamp tonnage also large, so the steel must be hard enough to avoid deformation. Otherwise, product will has flash after long time squeezing.

For hydraulic cylinder system, it is much stable than latch locking system, since it uses oil pressure to control demoulding speed. And hydraulic cylinder is not easy to break, so its mould life is longer than latch locking system, but its cycle time is longer.

If you want to develop crate mould, and want to know more about techincal points, pls feel free to contact with me, I will offer best solution for your project.

Chinese Battery Box Mold Maker

We are engaged in manufacturing, exporting and supplying a wide range of battery box molds.The offered range is available in various specifications as per customers’ requirements. Due to customers' trust, every year we export about 80sets battery box molds to all over the world and has enjoyed wide acclaim.

Commonly, battery box includes two parts: one is battery box base, another one is battery box cover. Below are specifications of battery box molds made by Sino Mould:

Product material: PP

Mold steel: DIN1.2738, 718H, P20

Mold life: 500K

Runner type: hot runner, one tip for battery box cover mold; but for battery box base mold, we suggest one tip for one lattice

Eject way: ejector pin for battery box cover; stripper plate for battery box base

The most important key point for battery box mold is to master how to control each lattice size, neither too loose nor too tight. If it is too loose, the battery box will get swell when charging; If it is too tight, the battery box will fail to charge. So our company had spent a lot of time to figure out the best solution to control the size. Before mold design, our engineer will do moldflow to analysis the deformation. According to the moldflow report, our designers will choose suitable position for injection point to keep injection balance. Also we will make the water channel more intensive to reach good cooling effect.
