Abstract
The utility model discloses an internal thread injection mold core mold insert comprises interior mold insert and outer insert cup joint, has gas passage between interior insert and the outer insert, through with internal thread mold core mold insert split be inside and outside coaxial two parts to enlarge gas passage, increase heat transfer efficiency, strengthen the gas cooling effect, improved production efficiency.
Description
Technical Field
The utility model belongs to the injection mold part specifically is a core mold insert for moulding plastics internal thread spare mould.
Background
The cooling mode of the core insert of the injection mold of the cylindrical internal thread type injection molding part is divided into two types according to the cooling medium: water circuit cooling and gas cooling. The threaded core insert needs to drive the core to rotationally demould through a mechanical structure (such as a gear) when the thread is removed, the water path cooling usually can cause the water leakage phenomenon at the rotating joint of the core insert, the gas can only exchange heat with the surface of the inner insert, and the heat conductivity and the specific heat capacity are not like liquid, so that the cooling period is longer, and the production efficiency is seriously reduced.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide an internal thread injection mold core mold insert that heat conduction efficiency is high, cooling cycle is short.
In order to solve the technical problem, the utility model discloses a technical scheme be: an internal thread injection molding core insert is formed by sleeving an inner insert and an outer insert, and a gas channel is arranged between the inner insert and the outer insert.
Preferably, the inner insert is a shaft body, and the outer insert is a cylinder body.
Preferably, the gas channel is divided into an inlet channel and an outlet channel.
By implementing the technical scheme, the internal thread core insert is split into the two parts which are coaxial inside and outside, so that the gas channel is enlarged, the heat transfer efficiency is improved, the gas cooling effect is enhanced, and the production efficiency is improved.

Figure 1 is a schematic diagram of an internally threaded injection core insert.
Detailed Description
The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1, the internally threaded injection core insert is comprised of an inner insert 3 and an outer insert 4. The inner insert is a shaft body, and the outer insert is a cylinder body.
An air inlet channel 5 and an air outlet channel 6 are arranged between the outer wall of the inner insert 3 and the inner wall of the outer insert 4, and the air inlet channel 5 and the air outlet channel 6 are communicated by a central hole 7.
The inlets and outlets of the air inlet channel 5 and the air outlet channel 6 are positioned at the die tooth socket 2, and the central hole is positioned at the die rear die core 1.
The inlet passage 5 and the outlet passage 6 may be designed to have a spiral structure in addition to the straight-through structure described above, so as to increase the heat exchange area (space).
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
