Injection Mold Plates
Three plates mold construction.
Injection mold plates. On these specifications the mold base with 2 plates is recommended to standard applications in plastic injection with the security and quality assured by polimold. C the core plate assembly. The main plates a plate and b plate and the structural plates top clamping plate bottom clamping plate support plate ejector plate space block and runner stripper plate etc. Weld lines jetting unfavourable shrinkage rates and wall thickness variation due to core.
What is injection moulding functions of mold base plates. B δΈ€ the intermediate or cavity plate. 3 plate mold usually uses pin point gate so it remove easy. A the feed plate assembly.
The mold base with 2 plates has 2 cavity plates that allow more than 680 000 combinations in 53 different sizes from 156x156mm to 696x996mm and with thickness from 22 to 196mm. A wide variety of plastic plates injection mold options are available to you such as plastic injection mould. According to its application the mold plate can be divided into two categories. To fully understand the principals involved in designing such a mould we must firstly understand the design requirements of the mould opening sequence.
Injection molding cycle is long. Mold structure is complex weak durability. One potential limitation of a 2 plate design is that the gate must come from the side of the part which has the potential to cause the following quality issues in some parts. All mold plates must be a minimum of sae 1030 steel.
From standard a series mold bases to the most complex custom mold bases for highly unique applications the plastics industry relies on dme mold bases for high quality material consistency and better productivity. A standard mold base is composed of four parts i e mold plate guide pin bushing return pin and screw. When designing a cold runner mold tool a 2 plate mold design should be considered first because it is easier and cheaper to make. Top plate bottom plate locate ring cavity plate core plate spacer block ejector plate stop pin.
Disadvantages of 3 plate mold mold is expensive. Two plate mold two plate mold is the easiest injection mold structure and has many advantages. Injection machine need large stroke. Milacron has the largest variety of mold bases in every regional standard configuration including imperial and metric.
It s consist with a side and b side 2 main parts when it is load in ejection machine to do molding a side is fixed and held still b side is movable. Product and runner can remove separately it is suitable for automation.
