In cold runner moulds, for multi-cavity and multi-point injection moulds, there is wreckage of material in runner area. Also wastage of material is more than component weight. To overcome the above problem, the technique used is hot Runner moulds. Hot runner mould is one of the improved manufacturing techniques for multi-cavity type moulds. These types of moulds are commonly used for large production rate. While producing plastic components using normal/standard multi-cavity mould, we are facing the problems like partial filling, cavities in components, less product quality, injection pressure and temperature reduction and war page etc. Thus we are redesigning the holder base by doing some modification in and this will be beneficial for our using purpose. We are making design of the component, mould flow analysis using software Solid works.


INTRODUCTION
In the injection moulding process, clamping force should be constant till the material is solidified and is ready to be ejected from the mould. This is the vernacular and preferable way of producing plastic products with any complexity and size.
The runner system sane the molten plastic material receiving from the barrel and pilot it into the mould cavity. Its configuration, dimensions, and connection with the moulded part influence the mould filling process and, therefore, largely the quality of the product. We can say, the runner system shows part quality and productivity. Runner systems in ordinary moulds have the same temperature level as the rest of the mould because they are in the same mould block. The best injection moulding system produce moulded parts of uniform density and free from all runners, flash, and gate stubs. To obtain this, a hot runner system, in contrast to a cold runner system, is employed. The material in the hot runners is preserve in a molten state and is not ejected with the moulded part. Unlike an ordinary cold runner, the hot runners are heated, so the plastic melt in the hot runners never solidified.

OBJECTIVES The prime objective is to design the Injection Mould tool to produce good quality Component and economically and also: Design and Analysis of Ceiling cable Holder Base To improve the aesthetic view and reduce material wastage. Provide strength to the holder base. Applying a shrinkage to the part material, geometry and moulding conditions. Make conceptual design of mould.

IV. DESIGN OF MOULD This section describes the design aspects and other
Considerations involved in designing the mould to manufacture holder Base.
Three design concepts are considered in designing of the mould including: i. Three-plate mould (Concept 1) has two parting line with single cavity. ii. Two-plate mould (Concept 2) has one parting line with many cavities with gating and ejection system. iii. Two-plate mould (Concept 3) has one parting line with single cavity without gating system.
For designing the mould second concept had been applied. First, the mould was designed based on the flat dimension of the plastic injection machine used. Mostly, core and cavity extraction was done on the basis of the criticality of the component, after core-cavity extraction from specified modeling software, mold base also modeled on the same software, at last core cavity inserts are assembled into the mold base. Determination of number of cavity From the above calculation of component and its shape and size 4 cavity moulds is preferred.

V. MOULD FLOW ANALYSIS
It is required to do the mould flow analysis for the particular component to know the proper filling and any other defects coming during the filling process of the component. To locate the proper gatting system and melt temperature of the material in which injection process takes place. Following are some images of analysis. TOOL ASSEMBLY Tool assembly is done in modeling software, includes the positioning of extracted core and cavity inserts into the mould base, after assembly 3D models are converted into the 2D drawings for manufacturing process. VII. CONCLUSION In this project, we carried out the Design and Analysis of Ceiling Cable Holder Base. The complete injection mould tool is designed for fabricating holder base by using solid work. The plastic flow analysis is carried out using solid work. All the results viz. fill time, temperature at the end of fill, weld lines, air traps, Ease of fill prediction are analysed and also we have design the mould tool assembly for holder base by considering standard design consideration and it has not shown any error in the mould flow analysis.
