Description

Modular die-casting drift for die-casting machine

Technical Field

The utility model belongs to the adapted part of die casting machine, especially a modular die-casting drift for die casting machine.

Background

The die-casting punch is a matched metal part arranged on a die-casting machine and is applied to be matched with an injection chamber, so that molten high-temperature molten aluminum and the like enter a die to be die-cast and formed.

Disclosure of Invention

The utility model discloses a aim at providing a novel die-casting drift for combined die-casting machine, its simple structure, use and maintain convenient and fast, because the die-casting drift of this invention patent design, the sliding sleeve position can carry out the substitution of the same model after wearing and tearing became invalid to can improve towards the wearability, it is long when having prolonged the labour of drift greatly, reduce the manufacturing cost of enterprise, play energy-concerving and environment-protective effect.

In order to achieve the above object, the technical solution of the present invention is achieved as follows.

The utility model provides a modular die-casting drift for die-casting machine, includes cylindric drift, sliding sleeve, and fastening nut is located the axial pilot hole at drift center, and the inner wall design has the internal thread of being connected usefulness with the die-casting machine, and the design has the external screw thread of being connected usefulness with fastening nut on the outer wall for fixed sliding sleeve position, the nut section of utilizing milling cutter to mill out of cylinder section behind the external thread section, be connected with the drift pole.

Further, an expansion joint with the width of a is formed in the sliding sleeve of the die-casting punch, and the specific size of a is determined according to the model of the die-casting punch.

Furthermore, the sliding sleeve of the die-casting punch can be adjusted into a single sliding sleeve or a double sliding sleeve according to requirements, and the specific working size can be adjusted appropriately according to the size of the die-casting punch.

Furthermore, if for two sliding sleeve drift, then a sliding sleeve terminal surface chamfer, and make the relative 180 installations in expansion joint on two sliding sleeves during the installation to reduce the sliding sleeve because the sliding sleeve expend with heat and contract with cold effect that the alternating temperature condition leads to.

Further, the sliding sleeve is installed in a replaceable mode, namely after the sleeve fails due to long-term wear, the sliding sleeve can be replaced by accessories of the same type and size.

Further, the die casting punch should be material compatible with the mating shot chamber so as to have the same coefficient of expansion and prevent deformation due to temperature changes during operation.

Compared with the prior art, the utility model discloses a have following advantage, the invention is through preliminary implementation, compares with prior art, shows following beneficial effect:

1. the use cost is greatly reduced, compared with the existing integral die-casting punch, the combined die-casting punch can improve the service time of the punch and reduce the production cost of enterprises, and has the same material performance and use effect as the integral die-casting punch;

2. through experimental verification, to the utility model discloses a die-casting drift of combination formula is proposed compares with traditional die-casting drift in the aspect of the result of use, and its life is showing and is improving.

Detailed Description

The following describes the present invention with reference to the accompanying drawings.

As shown in fig. 1, 2, 3, 4 and 5, a die-casting punch for a combined die-casting machine comprises a cylindrical punch 01, a single sliding sleeve 02 or a double sliding sleeve 04, a fastening nut 03, an inner wall designed with an internal thread 011 for connecting with a die-casting machine, an outer wall designed with an external thread 012 for connecting with the fastening nut for fixing the sliding sleeve, and a cylindrical section connected behind the external thread section is a nut section milled by a milling cutter for connecting with a punch rod.

In this embodiment, an expansion joint 021 with a width a is formed on the sliding sleeve of the die-casting punch, and the specific size of a is determined according to the model of the die-casting punch.

In this embodiment, the sliding sleeve of the die-casting punch can be adjusted to the single sliding sleeve 02 or the double sliding sleeve 04 according to the requirement, and the specific working dimension can be adjusted appropriately according to the size of the die-casting punch.

In this embodiment, if for two sliding sleeve drifts, then an end face chamfer of sliding sleeve, and make the relative 180 degrees of expansion joint on two sliding sleeves install during the installation to reduce the sliding sleeve because the sliding sleeve expend with heat and contract with cold effect that the alternating temperature condition leads to.
