Description

For a multi-cavity mold needle valve hot runner
Technical field
The utility model relates to Hot runner Technology, specifically a kind of for a multi-cavity mold needle valve hot runner.
Background technology
The hot runner system structure of existing a multi-cavity mold needle-valve mould as shown in Figure 1, comprise tank plate 1, oil cylinder 2, flow distribution plate 3, hot mouth 4 and needle 5, wherein a needle is only with by each oil cylinder, because the volume of oil cylinder limits, can not use for closely spaced product, each oil cylinder is only with a needle, hot runner structure more complicated simultaneously, makes manufacturing cost high simultaneously.
Utility model content
The purpose of this utility model is to provide a kind of for a multi-cavity mold needle valve hot runner, drive a needle to be improved to four oil cylinders an existing oil cylinder and drive whole needle plate, greatly reduce the spacing of product, decrease oil cylinder quantity and greatly reduce manufacturing cost.
For achieving the above object by the following technical solutions:
A kind of for a multi-cavity mold needle valve hot runner, comprise tank plate, oil cylinder, flow distribution plate, hot mouth and needle, oil cylinder is fixed on tank plate, it is characterized in that: the piston-rod lower end of described oil cylinder connects needle fixed head, the upper end of described needle is fixed on needle fixed head, and needle bottom is placed in hot mouth through flow distribution plate, and hot mouth is fixed on the bottom of flow distribution plate; Between described needle fixed head and flow distribution plate, also arrange connecting plate, also arrange cushion block between connecting plate and tank plate, cushion block is positioned at the both sides of needle fixed head, and the thickness of cushion block is greater than the thickness of needle fixed head.
Described flow distribution plate inside arranges transverse flow channels and longitudinal runner, transverse flow channels and longitudinal runner are interconnected, the port of described transverse flow channels is equipped with end cap, described end cap comprises plug screw and tapering sealing, inclined plane shape is arranged in tapering sealing end, to turn buffering transitional function longitudinal runner from transverse flow channels at fluid.
Described tank plate is arranged on four oil cylinders, and four oil cylinder Central Symmetries are distributed on tank plate.
An existing oil cylinder drives a needle to be improved to more than one oil cylinder and drives whole needle plate by the utility model, greatly reduces the spacing of product, also has use at Small Distance product, decrease oil cylinder quantity simultaneously and greatly reduce manufacturing cost.

Fig. 2 is internal structure schematic diagram of the present utility model;
Fig. 3 is the structural representation of the utility model other direction;
Fig. 4 is the utility model perspective view;
Fig. 5 is the internal structure schematic diagram of existing flow distribution plate;
Fig. 6 is the utility model flow distribution plate internal structure schematic diagram.
Detailed description of the invention
As in Figure 2-4, a kind of for a multi-cavity mold needle valve hot runner, comprise tank plate 1, four oil cylinders 2, flow distribution plates 3, hot mouth 4 and needle 5, four oil cylinder 2 Central Symmetries are distributed in tank plate 1, and the piston-rod lower end of described oil cylinder 2 connects needle fixed head 6, and the upper end of described needle 5 is fixed on needle fixed head 6, needle 5 bottom is placed in hot mouth 4 through flow distribution plate, and hot mouth 4 is fixed on the bottom of flow distribution plate 3; Between described needle fixed head 6 and flow distribution plate 3, also arrange connecting plate 7, also arrange cushion block 8 between connecting plate 7 and tank plate 1, cushion block 8 is positioned at the both sides of needle fixed head 6, and the thickness of cushion block 8 is greater than the thickness of needle fixed head 6.
Because the thickness of cushion block is greater than the thickness of needle fixed head during work, four synchronous valve needle fixed heads of oil cylinder move back and forth, and needle fixed head drives needle-valve working in reciprocating mode; An existing oil cylinder drives a needle to be improved to more than one oil cylinder and drives whole needle plate by the utility model, greatly reduces the spacing of product, also has use at Small Distance product, decrease oil cylinder quantity simultaneously and greatly reduce manufacturing cost.
In addition as shown in Figure 5, existing flow distribution plate 3 transverse flow channels port generally adopts, and plug screw 11 and T-shaped are faced sealing plug 12 directly and added that flat seal copper ring 13 realizes sealing again, and existing this structure processed complex, cost is high, sealing effect is undesirable.
As shown in Figure 6, flow distribution plate 3 inside described in the utility model arranges transverse flow channels 14 and longitudinal runner 15, transverse flow channels 14 and longitudinal runner 15 are interconnected, the port of described transverse flow channels 15 is equipped with end cap, described end cap comprises plug screw 11 and tapering sealing 16, inclined plane shape 17 is arranged in tapering sealing 16 end, to turn buffering transitional function longitudinal runner from transverse flow channels at fluid; It is simple that the utility model directly adopts the sealing of plug tapering to process, and manufacturing cost reduces, owing to adopting tapering sealing, sealing better effects if.
