Description
Technical field
The utility model is related to a kind of TOP-TIP, more particularly to a kind of hot runner flow distribution plate.
Background technology
Flow distribution plate be called hot runner flow distribution plate it be TOP-TIP central module, it by sprue nozzle transmission come
Plastic melt is distributed to each injection point nozzle through runner.Flow distribution plate can be such that the die cavity of mould uniformly fills, plastics balance flowing,
System thermal is balanced.
In the prior art, the front end face of flow distribution plate is provided with hot nozzle, wherein, set in the runner of the front end face of flow distribution plate
There is screw, hot nozzle is directly mounted in the screw.If the thread damage in screw, need to carry out monoblock flow distribution plate more
Change, high cost.Meanwhile, meanwhile, after flow distribution plate is installed in mould, if necessary to repair, flow distribution plate weight is big, and shunting
Plate temperature is higher, takes out especially inconvenient.
The content of the invention
The utility model purpose is to provide a kind of hot runner flow distribution plate, by using the structure, reduces maintenance cost, carries
Efficiency is changed in the maintenance of flow distribution plate high.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：A kind of hot runner flow distribution plate, including flow distribution plate
Body, the flow distribution plate bodies top is provided with least one location hole, and thermal jet is provided with the front end face of the flow distribution plate body
Mouth, the front end face of the flow distribution plate body is provided with a groove, and the groove has been embedded in a location-plate, before the location-plate
End face is flushed with the front end face of the flow distribution plate body, and the center of the location-plate front end face is provided with runner, in the runner
The first internal thread is provided with, one end of the hot nozzle is installed in the runner through first internal thread；The location-plate
Two indent screws are additionally provided with front end face, two indent screws are symmetricly set in the both sides of the runner.
In above-mentioned technical proposal, the location-plate coordinates with the groove gap.
In above-mentioned technical proposal, the second internal thread is provided with the location hole.
In above-mentioned technical proposal, heater strip, the surface of the heater strip are embedded with the front end face of the flow distribution plate body
It is coated with copper bar.
Because above-mentioned technical proposal is used, the utility model has following advantages compared with prior art：
1. the front end face in the utility model in flow distribution plate sets groove, and hot nozzle is installed in groove through a location-plate,
Compared with the structure that conventional hot nozzle is directly mounted in shunting plate runner, if the first thread damage in runner, it is only necessary to
Location-plate is changed, without changing monoblock flow distribution plate, cost is less expensive, extends the service life of flow distribution plate；
2. two indent screws are additionally provided with the utility model on location-plate front end face, and two indent screws are symmetrical
The both sides of the runner are arranged at, by the setting of indent screw, are easy to the dismounting and change of location-plate；
3. location hole is used to position when installing in the utility model, by setting the second internal thread in location hole, with
The positioning pore structure that internal thread is not provided with toward location hole is compared, when flow distribution plate body needs detachable maintaining, it is only necessary to use
Flow distribution plate body can be pulled out from mould in second internal thread of bolt precession location hole, convenient disassembly is easy to flow distribution plate
Maintenance；
4. heater strip is embedded with the front end face of flow distribution plate described in the utility model, and the surface of the heater strip is coated with
Copper bar, by the covering of copper bar, makes the heat conduction of heater strip more uniform, and effectively heater strip is protected, and prevents heater strip
Damage.

Specific embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to the utility model：
Embodiment one：Referring to shown in Fig. 1,2, a kind of hot runner flow distribution plate, including flow distribution plate body 1, the flow distribution plate sheet
The top of body 1 is provided with two location holes 2, and hot nozzle 3, the flow distribution plate body 1 are provided with the front end face of the flow distribution plate body 1
Front end face be provided with a groove 4, the groove 4 has been embedded in a location-plate 5, the front end face of the location-plate 5 with described point
The front end face of stream plate body 1 is flushed, and the center of the front end face of the location-plate 5 is provided with runner 6, the runner 6 and is provided with first
Internal thread 7, one end of the hot nozzle 3 is installed in the runner 6 through first internal thread 7；The front end of the location-plate 5
Two indent screws 8 are additionally provided with face, two indent screws 8 are symmetricly set in the both sides of the runner 6.
