Structure, with simple structure, the cold burden line of the plastic part surface in mould that avoids modifying mould overall structure, eliminate, is reduced
Mould saves die trial cost in the die trial number of times of injection moulding machine, energy-conserving and environment-protective, improves die life, facilitates mould zero
The features such as part is changed when damaging.
The utility model solves the technical scheme that its technical problem used：There is provided a kind of for injection mold submarine
The cutting structure of cast gate, including sub-marine gate mold insert, cutter and straight push rod, described sub-marine gate mold insert side are disposed with
Straight push rod, sprue channel is disposed with described sub-marine gate mold insert, and runner is pushed up with sub-marine gate mold insert near straight with one voice
Bar side is disposed with Cutting tool installation manner groove, and the insertion of Cutting tool installation manner groove top is provided with cutter, and described straight push rod is poured near submarine
Runner gap is disposed between the top of mouth mold insert side and sub-marine gate mold insert, described cutter lower disposed has cutting edge,
Described straight push rod upper end is provided with the plastic product connected with runner gap.
The cutting edge of described cutter is towards the sprue channel direction of sub-marine gate mold insert.
It is same vertical that described sub-marine gate mold insert is in cutter near straight push rod side near straight push rod side
In plane.
Described sub-marine gate mold insert upper surface middle part is disposed with runner hole, and runner hole lower end is disposed with towards Cutting tool installation manner
The sprue channel of groove lower tilt.
Described cutter uses metal material of the hardness between HRC58~62.
The angle of described cutting edge is between 25~45 degree.
Beneficial effect：The utility model is related to a kind of cutting structure for injection mold sub-marine gate, with structure
Simply, avoid modifying mould overall structure, eliminate plastic part surface in mould cold burden line, reduce mould and be molded into
The die trial number of times of type machine, saves die trial cost, energy-conserving and environment-protective, carries out when improving die life, facilitating mould parts to damage
The features such as replacing.

Specific embodiment
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation scope of the present utility model.In addition, it is to be understood that reading the content of the utility model instruction
Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values equally fall within this Shen
Please appended claims limited range.
Implementation method of the present utility model is related to a kind of cutting structure for injection mold sub-marine gate, such as Fig. 1-4
It is shown, including sub-marine gate mold insert 2, cutter 3 and straight push rod 1, the described side of sub-marine gate mold insert 2 is disposed with straight push rod
1, sprue channel is disposed with described sub-marine gate mold insert 2, runner is close to straight push rod 1 with sub-marine gate mold insert 2 with one voice
Side is disposed with Cutting tool installation manner groove, and the insertion of Cutting tool installation manner groove top is provided with cutter 3, and described straight push rod 1 is poured near submarine
Runner gap is disposed between the top of mouth mold insert 2 side and sub-marine gate mold insert 2, the described lower disposed of cutter 3 has sword
Mouth 5, the described upper end of straight push rod 1 is provided with the plastic product 4 connected with runner gap.
The cutting edge 5 of described cutter 3 is towards the sprue channel direction of sub-marine gate mold insert 2.
Described sub-marine gate mold insert 2 is in same with cutter 3 near the side of straight push rod 1 near the side of straight push rod 1
On perpendicular.
The described upper surface of sub-marine gate mold insert 2 middle part is disposed with runner hole, and runner hole lower end is disposed with towards cutter peace
The sprue channel of tankage lower tilt.
Metal material of the described cutter 3 using hardness between HRC58~62.
The angle of described cutting edge 5 is between 25~45 degree.
Embodiment
The plastics liquation of molten condition is injected into injection by injection mold by injection machine first when product is produced
In the die cavity of mould, usual plastics liquation is entered into die cavity from gum-injecting port, and plastics liquation is from sub-marine gate in this technology
