Abstract
The invention discloses an air-cooling structure for an insert pin of a plastic mould. The air-cooling structure comprises the insert pin, wherein the insert pin is provided with a blind hole; a guide tube is inserted into the blind hole; an outer channel is formed between the guide tube and the blind hole; the outer wall of the guide tube is connected with a fixator which is positioned between the guide tube and the blind hole; the guide tube is fixed to the blind hole through the fixator; the guide tube and the outer channel form a gas path; the guide tube is connected to a cooling gas source. The air-cooling structure can realize effective cooling on the insert pin.
Description
Technical field
The present invention relates to injection molding technology field, be specifically related to a kind of mould of plastics pin air cooling structure.
Background technology
The pin of mould of plastics is limited due to structure and size, it has not been convenient to offers and cools down it near the horizontal medium cooling duct of liquid plastic.
Summary of the invention
It is an object of the invention to provide a kind of mould of plastics pin air cooling structure, this air cooling structure can realize effectively cooling to pin.
For achieving the above object, the present invention provides following technical scheme:
A kind of mould of plastics pin air cooling structure, including pin, this pin is provided with blind hole, being inserted with conduit in above-mentioned blind hole, form outer tunnel between above-mentioned conduit and above-mentioned blind hole, the outer wall of this conduit connects fixture, above-mentioned fixing piece is between above-mentioned conduit and above-mentioned blind hole, above-mentioned conduit is fixed with above-mentioned blind hole by fixture, and above-mentioned conduit, outer tunnel form air flue, and above-mentioned conduit is connected to cool down source of the gas.
Preferably, the outer end of above-mentioned blind hole is provided with female thread, and above-mentioned fixing piece is fixing post, and the outer wall of fixing post is provided with external screw thread, and above-mentioned female thread and above-mentioned external screw thread are threaded connection, and above-mentioned fixing post is provided with through hole.
Preferably, above-mentioned fixing piece is resilient extrusion.
Preferably, the outer wall of pin is provided with gas-flow deflector, and this gas-flow deflector is used for so that air-flow flows along pin length direction.
The operation principle of the present invention is: offer longitudinal blind hole in the end of pin, the bottom of blind hole is near plastic liquid, conduit is inserted in blind hole, blind hole is become an air flue being available for cold air flow, so when cold airflow is through blind via bottom, can realize the cooling at plastic liquid close on pin.Gas cooling is used will not product to be had any impact, because it will not occur the leakage of liquid medium, in addition, the terminal of blind hole need not use sealing member, the terminal of blind hole introduces a gas into specific end-of-medium also without use key, because gas can be directly discharged into air, surrounding is i.e. the terminal of cooling gas.
The invention have the benefit that this air cooling structure can realize effectively cooling to pin.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the detailed description of the invention of the present invention is further described.Following example are only used for clearly illustrating technical scheme, and can not limit the scope of the invention with this.
The technical scheme that the present invention is embodied as is:
As shown in Figure 1, a kind of mould of plastics pin 1 air cooling structure, including pin 1, this pin 1 is provided with blind hole 11, is inserted with conduit 2 in above-mentioned blind hole 11, outer tunnel is formed between above-mentioned conduit 2 and above-mentioned blind hole 11, the outer wall of this conduit 2 connects fixture 3, and above-mentioned fixing piece 3 is between above-mentioned conduit 2 and above-mentioned blind hole 11, and above-mentioned conduit 2 is fixed with above-mentioned blind hole 11 by fixture 3, above-mentioned conduit 2, outer tunnel form air flue, and above-mentioned conduit 2 is connected to cool down source of the gas 5.
The outer end of above-mentioned blind hole 11 is provided with female thread, and above-mentioned fixing piece 3 is fixing post, and the outer wall of fixing post is provided with external screw thread, and above-mentioned female thread and above-mentioned external screw thread are threaded connection, and above-mentioned fixing post is provided with through hole.
Above-mentioned fixing piece 3 is resilient extrusion.
The outer wall of pin 1 is provided with gas-flow deflector 4, and this gas-flow deflector 4 is used for so that air-flow flows along pin 1 length direction.
The operation principle of the present invention is: offer longitudinal blind hole 11 in the end of pin 1, the bottom of blind hole 11 is near plastic liquid, conduit 2 is inserted in blind hole 11, blind hole 11 is become an air flue being available for cold air flow, so when cold airflow is bottom blind hole 11, can realize the cooling at plastic liquid close on pin 1.Gas cooling is used will not product to be had any impact, because it will not occur the leakage of liquid medium, in addition, the terminal of blind hole 11 need not use sealing member, the terminal of blind hole 11 introduces a gas into specific end-of-medium also without use key, because gas can be directly discharged into air, surrounding is i.e. the terminal of cooling gas.
The invention have the benefit that pin 1 can be realized effectively cooling down by this air cooling structure.
The above is only the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, on the premise of without departing from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention.
