Bucket mold is one of our most important plastic injection mold, our bucket mold includes food bucket mold, pail mold, cylinder bucket mold, square shape bucket mold, water bucket mold, industrial paint bucket mold, fishing bucket mold, packing bucket mold, dustbin bucket mold,How to make a good plastic paint bucket mould?
1.Firstly, Bucket Mold Design and Structure
A high-quality mold structure is a premise for a qualified mold before manufacturing.Moldflow is important to analyze mold structure,
including demolding draft angle, the epitome of product surface, gating system design, exhaust design, cooling system design etc.The main problems that may easily occur will through trial and error during the bucket mold structure design.
2. Second, Bucket Mold Steel
In order to improve the mold life and product quality, we increase the mold steel hardness through
heat treatment. The steels we commonly use are H13(48-52HRC), 2316(45-50HRC) etc.to prevent mold
eccentric, we use whole piece of steel to make the bucket. The cooling system is very important. We
adopt single loop cooling way and setup even distribution water channels as much as possible. To
enhance the cooling effect, BeCu can be inserted on the core and cavity. All small sliders will be nitride
to increase the hardenss.It is important to keep maintenance for the moulds. We should check and make
sure the the water channels and air circuit unlocked. Add lubricant oil for the siliders, regularly clean the
stripper plate and centre ejector.
3. Third, the bucket Mold Cooling system
Cooling system design is a relatively cumbersome work, namely to consider the uniformity of the
cooling and the cooling effect, also the impact brings to the overall mold structure, determining the exact location and size of the cooling system; and cooling for key positions such as moving plate or the inserts, side sliders as well as side cores;standard cooling element design and the selection of the cooling standard components. We analyzes all series of factors when begin to start the mold design. The mold has recycled water to flow in every part of it which reduces the cooling time, improves the production efficiency and greatly reduces products costs.
