Abstract
The invention discloses a die-casting machine punch. The die-casting machine punch comprises a punch outer sleeve (3) and a punch inner sleeve (4). The punch outer sleeve (3) and the punch inner sleeve (4) are connected and fastened in a threaded mode and provided with two seals. A spiral water channel and a fastening thread are arranged on the surface of the punch inner sleeve (4). After the punch outer sleeve (3) and the punch inner sleeve (4) are assembled, one end is connected with a punch rod, and the other end is connected with a pressing chamber. The middle of the punch inner sleeve (4) is connected with a water core (2). The pressing chamber (5) is connected with a pressing chamber water jacket (6). The punch rod (1) is connected with the water core (2) and provided with two seals. Abrasion to the expensive pressing chamber is relieved, generation of harmful dust is greatly reduced, economic benefits are increased, and the cost of consumables is lowered.
Description
Technical field
The present invention relates to high-pressure casting field.
Background technology
Drift be high-pressure casting must high level easily-consumed products.At present, the drift material therefor of prior art is various, and scene makes
Expansion rate is different, and the required precision to equipment is high, and using effect is unsatisfactory.Drift influence productive temp is frequently changed,
To the serious wear of pressure chamber.Drift oil need to be instilled in pressure chamber, and harmful vapors are big, have a strong impact on that employee is healthy and environment peace
Entirely.
The content of the invention
The shortcoming of existing drift is overcome, the invention provides a kind of improved die casting machine punch.
Die casting machine punch, including drift overcoat, drift inner sleeve, jumper bar are connected with water core, are equipped with two seals.Outside drift
Set, drift inner sleeve are equipped with two seals to be threadedly coupled fastening.Drift inner sleeve surface sets spiral channel and fastening thread.Punching
After head overcoat, the assembling of drift inner sleeve, one end is connected with jumper bar, and the other end is connected with pressure chamber；Drift inner sleeve middle part is connected with water core.
Pressure chamber is connected with pressure chamber water jacket.
By verification experimental verification, the present invention under 3 kilograms of pressure cycle waters uninterruptedly cooling, with 20 points of gas welding continuous heating
Clock, the expansion rate of drift external diameter goes to zero, and drift is in room temperature state, mitigates the abrasion to expensive pressure chamber, greatly alleviates
The generation of noxious fume, increased economic benefit, reduce consumables cost.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is schematic diagram when die casting machine punch of the present invention is used.
In figure：1 is jumper bar, and 2 is water core, and 3 is drift overcoat, and 4 is drift inner sleeve, and 5 is pressure chamber, and 6 is pressure chamber water jacket.
Specific embodiment
As shown in drawings, die casting machine punch, including drift overcoat 3, drift inner sleeve 4, jumper bar 1 are connected with water core 2, are equipped with two
Road is sealed.Drift overcoat 3, drift inner sleeve 4 are equipped with two seals to be threadedly coupled fastening.The surface of drift inner sleeve 4 sets spiral water
Road and fastening thread.After drift overcoat 3, drift inner sleeve 4 are assembled, one end is connected with jumper bar, and the other end is connected with pressure chamber；In drift
It is connected with water core 2 in the middle of set 4.Pressure chamber 5 is connected with pressure chamber water jacket 6.
It is clear that the invention is not restricted to the description of specific embodiment, other inspire the skill for obtaining according to specific embodiment
Art scheme, belongs to protection scope of the present invention.
