Description
Technical field
This utility model relates to a kind of simple TOP-TIP, belongs to Hot runner Technology field.
Background technology
Special (moldbest) TOP-TIP such as Fig. 1 of bass, shown in 2, it is made up of four parts: hot nozzle 6, flow distribution plate 4, heating element (being arranged on the heating collar 7 outside hot nozzle 6) and temperature controller 9, injection molding machine nozzle 1 is matched with the main sprue bush 3 of mould by locating ring 2, main sprue bush 3 is connected with the flow distribution plate 4 of TOP-TIP, flow distribution plate 4 is fixed in mould by flow distribution plate limited block 5, the outlet of flow distribution plate 4 inner flow passage 16 is connected with die cavity by corresponding hot nozzle 6, outside hot nozzle 6, heating collar 7 is installed, TOP-TIP is connected with temperature controller 9 by connector socket 10.Raw material makes goods 8 in entering mould by TOP-TIP.In TOP-TIP, the effect of each parts is as follows:
1, hot nozzle 6: the plastics entered from flow distribution plate 4 are sent into each die cavity again, fully reduce injection pressure；
2, flow distribution plate 4: connect injection molding machine nozzle 1 and hot nozzle 6, penetrating plastics constant temperature nozzle deliver to each single hot nozzle 6 from main；
3, heating element: heating element heater is the important component part of TOP-TIP, its heating accuracy and service life are the biggest for the control of Shooting Technique and the working stability impact of TOP-TIP.Typically there are heating rod, heating collar, add heat pipe etc.；
4, temperature controller 9: temperature controller 9 carries out temperature controlled instrument to each position of TOP-TIP exactly, bottom have break-make position formula respectively to high-end, the kind such as integral differential proportional control type and Novel intelligent temperature controller.
Before injection-molded item 8, first open temperature controller 9 and make the hot nozzle 6 of heating collar 7 be heated to plastics melt temperature, it is ensured that before plastic raw materials enters mold cavity, plastic raw materials does not solidifies.Injection machine is by the thrust of screw rod (or plunger), the plastics of the molten condition (i.e. viscous state) plastified are become owner of in sprue bush 3 by injection molding machine nozzle 1 injection, enters back on flow distribution plate 4, subsequently into hot nozzle 6, enter back into die cavity, after cured sizing, obtain goods 8.
The defect of above-mentioned TOP-TIP is:
1, cost is high, as a example by special (moldbest) hot flow path of bass, and different product, need different hot flow paths, so hot flow path needs specially from the customization of hot flow path producer, a set of simple hot flow path price is about 10,000；
2, hot runner structure is compared more complicated, it is desirable to strict temperature control；
3, professional person is needed to safeguard.
Summary of the invention
Problem to be solved in the utility model is that existing hot runner system structure is complicated, and cost is high, high to temperature control requirement, and needs special messenger to safeguard.
In order to solve the problems referred to above, this utility model provides a kind of simple TOP-TIP, including the flow distribution plate being connected with main sprue bush, connector socket and the temperature controller connected in connector socket, it is characterised in that each outlet of described flow distribution plate inner flow passage is connected with die cavity by a point of sprue bush；Being provided with heating rod in described flow distribution plate, heating rod power line exposes from flow distribution plate and is connected with connector socket.
Preferably, being provided with the flow distribution plate temp.-sensing wire for monitoring flow distribution plate temperature in described flow distribution plate, flow distribution plate temp.-sensing wire exposes from flow distribution plate and is connected with connector socket.
This utility model have employed a kind of simple TOP-TIP increasing temperature sensing device on heating rod heating base, this kind of simple hot flow path is that the runner both sides in flow distribution plate are respectively mounted two heating rods, the plastic liquid melted is made to be maintained at flow regime for a long time, two temp.-sensing wires are installed on flow distribution plate simultaneously, the temperature of plastic liquid in runner can be fed back in time, and the temperature of heating rod can be adjusted in time.Labyrinth is simplified by this utility model, thus reduces die cost, and simple in construction, it is simple to installs and safeguards.

Detailed description of the invention
For making this utility model become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Embodiment
As seen in figures 3-6, structural representation for a kind of simple TOP-TIP that this utility model provides, including the flow distribution plate 4 being connected with main sprue bush 3, connector socket 10 and the temperature controller 9 connected in connector socket 10, each outlet of flow distribution plate 4 inner flow passage 16 is connected with die cavity by a point of sprue bush 14；Being provided with heating rod 6 in described flow distribution plate 4 and for monitoring the flow distribution plate temp.-sensing wire 12 of flow distribution plate 4 temperature, heating rod power line 11, flow distribution plate temp.-sensing wire 12 expose from flow distribution plate 4 and are connected with connector socket 10.In the present embodiment, the runner 16 of flow distribution plate 4 is opened to flow distribution plate 4 to direction, flow distribution plate 4 both sides from middle part import department, and blocks two ends with copper plug 13, and its effect one is easy for processing flow channel 16, and two is to preferably add hot charge, and heating surface increases.
During use, being fixed in mould by flow distribution plate limited block 5 by flow distribution plate 4 of the present utility model, the import of flow distribution plate 4 inner flow passage 16 is directed at main sprue bush 3, and main sprue bush 3 is fixed with mould by locating ring 2.
Goods 8 in the present embodiment are flowerpot, and material is polypropylene (PP), melt temperature: 230～275 DEG C.Before injection-molded item 8, first open temperature controller 9 and make 15 flow distribution plates 4 of heating rod be heated to plastics melt temperature, it is ensured that plastic raw materials runner 16 on flow distribution plate 4 keeps flow regime.Flow distribution plate 4 temperature can pass through flow distribution plate temp.-sensing wire 12, feeds back to information on temperature controller 9, thus learns flow distribution plate 4 temperature.When flow distribution plate 4 is heated to plastics melt temperature, injection machine is by the thrust of screw rod (or plunger), the plastics of the molten condition (i.e. viscous state) plastified are become owner of in sprue bush 3 by injection molding machine nozzle 1 injection, enter back on flow distribution plate 4, subsequently into a point sprue bush 6, enter back into die cavity, after cured sizing, obtain goods 8.
In order to reduce cost, flow distribution plate 4 can use common mould steel with a point sprue bush 6.
