Plastic Commodity Mould
Plastic mold can be seen as composed of as follows some features of similar parts.
(1) Molding parts. Is direct contact with the plastic molding parts, and decided to plastic parts shape and dimensional accuracy of parts, shall constitute a part of the cavity, as shown in figure 3-45 of the five core 4, concave die, etc., they are the mold of the main parts.
(2) Gating system. Gating system is to put the plastic melt by the injection machine nozzle or mold cavity to cavity of a set of feeding channel feeding, including: gate sets of 8 and open in the parting surface of flow channel, as shown in figure 3-45.
(3) Guide positioning. Guide positioning system is mainly used to ensure the dynamic and closed at the time of the guide and positioning of the mould installation of the guide on positioning with injection machine and etc. In general, moving, or closed at the time of the guide and positioning guide pillar and guide sleeve, and is often used to or part in moving die set fits inside and outside the cone positioning: launch institutions oriented often use push plate guide pillar and push board guide bush. As shown in figure 3-45 guide positioning of guide pin 3 and the guide hole on the template 10 etc.
(4)Launch institutions. Launch mechanism is used for parts in the mould process and flow condensation from the molding part and runner push or pull out parts.. 45 as shown in figure 3 - the launch of the agency by the push rod, pull rod 2 1, pushing plate fixed plate and push plate 14 15, etc.
(5) The side parting core-pulling mechanism. Side parting core-pulling mechanism used in mould launched out before molding parts stamping concave hole or upper side of the core components. Figure 3 is not set to 45 side parting core-pulling mechanism.
(6)The exhaust system. Exhaust system used to vent the air inside the cavity in the forming process and the structure of plastic itself comes out of gas
(7)Cooling and heating device. The cooling and heating device is designed to meet the requirements of molding process of mould temperature device.
(8)Supporting and fixed parts. Main bearing and fixed parts assembly, positioning and connecting role, as shown in figure 3-45
Plastic mould is relying on the coordination between the various parts to complete plastic stamping shape function. Of course, not all of the plastic mould has the above all kinds of parts, but the molding parts to meter system, institutions and the necessary supporting fixed parts is necessary.
