Technical Field

The utility model relates to the field of hot runner systems, in particular to a hot runner sharp mouth assembly.

Background

The sharp mouth subassembly is a very important part among the hot runner system, present sharp mouth subassembly includes the body (is the tube-shape), heat conduction cover and double-end point needle are constituteed, wherein the heat conduction cover sets up at this internally, the double-end point needle sets up in the heat conduction cover, two ends of double-end point needle are located this external, the sharp mouth subassembly of this kind of structure is because the heat conduction cover is established at this internally, it is relatively poor to cooperate stability between heat conduction cover and the body and between heat conduction cover and the double-end point needle, so the sharp mouth subassembly of this kind of structure takes place easily between each part in the use and breaks away from, the stability of whole structure is relatively poor.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the problems and provides a hot runner sharp mouth assembly.

The technical scheme adopted by the utility model is as follows:

the utility model provides a hot runner sharp mouth subassembly, includes barrel, awl head and sharp head post, sharp head post set up in the barrel, sharp head post with barrel integrated into one piece, the awl head sets up on sharp head post, and the awl head has formed the sharp needle of double-end with sharp head post cooperation together.

In this kind of hot runner sharp mouth subassembly, sharp head post and barrel integrated into one piece, and the one end of sharp head post is sharp needle form, only need install a conical head and can accomplish the equipment, and whole subassembly only has a erection joint structure, and structural stability is high.

Optionally, the conical head and the pointed column are matched together in a threaded connection mode.

The threaded connection is adopted, so that disassembly and maintenance are convenient.

Optionally, the pointed column is a hollow pointed cone column.

Because whole barrel and sharp-pointed post are integrated casting shaping, hollow formula sharp-pointed post can reduce raw materials and consume, also is convenient for the drawing of patterns after pouring the shaping simultaneously.

Optionally, the support column is located in the pointed conical column, and the support column abuts against the conical head.

The liquid flow direction of the tip subassembly is by one side flow direction tip post one side of conical head in concrete this, so set up the support column in the tip post, in the cavity of support column position tip post, the support column can play the supporting role to the conical head, avoids the conical head to move in the cavity of tip post under the extrusion of plastics liquid, ensures that the structure of whole tip subassembly remains stable throughout.

Optionally, the outer wall of the cylinder is provided with threads.

Optionally, a ring is arranged on the outer wall of the cylinder.

The ring is arranged to ensure that a hand can smoothly contact the cylinder body when the sharp mouth component is assembled, so that the cylinder body is convenient to screw.

Optionally, a connecting sheet is arranged between the cylinder body and the pointed column, and the cylinder body, the pointed column and the connecting sheet are integrally formed.

The connecting piece is used for supporting the pointed column.

Optionally, the connecting pieces are three, and the three connecting pieces are distributed around the pointed column at equal intervals and in equal radian.

The three connecting sheets can ensure that the fixed barrel can be stably supported, and also ensure that the plastic liquid can stably flow through the connecting sheets, and the connecting sheets equally divide the plastic liquid, so that the discharge of the plastic liquid at the barrel opening of the barrel can be ensured to be stable.

The cylinder, the connecting sheet, the pointed column and the conical head are all made of steel, and the supporting column is made of aluminum or red copper.

The utility model has the beneficial effects that: the pointed column and the barrel are integrally formed, one end of the pointed column is in a pointed needle shape, the assembly can be completed only by installing one conical head, the whole assembly only has one installation and connection structure, and the structural stability is higher.

Description of the drawings:

figure 1 is a schematic diagram of a hot runner tip assembly,

FIG. 2 is a schematic cross-sectional view of a hot runner tip assembly.

The figures are numbered: 1. a barrel; 2. connecting sheets; 3. a conical head; 4. a tip post; 5. and (4) a support column.

The specific implementation mode is as follows:

the present invention will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1 and 2, the hot runner sharp mouth component comprises a cylinder 1, a conical head 3 and a sharp head column 4, wherein the sharp head column 4 is arranged in the cylinder 1, the sharp head column 4 and the cylinder 1 are integrally formed, the conical head 3 is arranged on the sharp head column 4, and the conical head 3 and the sharp head column 4 are matched together to form a double-head sharp needle.

In this kind of hot runner sharp mouth subassembly, sharp head post 4 and barrel 1 integrated into one piece, and the one end of sharp head post 4 is sharp needle form, only needs a conical head 3 of installation to accomplish the equipment, and whole subassembly only has a erection joint structure, and structural stability is high.

As shown in fig. 1 and 2, the conical head 3 and the pointed column 4 are matched together in a threaded manner.

As shown in fig. 1 and 2, the pointed column is a hollow pointed column.

Because whole barrel 1 and sharp-pointed post 4 are integrated into one piece casting shaping, hollow type sharp awl post can reduce raw materials consumption, also is convenient for the drawing of patterns after pouring the shaping simultaneously.

As shown in fig. 1 and fig. 2, the device further comprises a supporting column, wherein the supporting column is positioned in the pointed conical column and props against the conical head 3.
