Embodiment Construction

[0038] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0039] Such as figure 1 As shown, the present invention includes a plunger 1, a ball joint 2, a cooling water delivery assembly 3 and a punch assembly 4, the ball end of the ball joint 2 is installed in one end of the punch assembly 4, The other end is installed in one end of the injection rod 1 . Such as image 3 As shown, the ball joint 2 enables the punch assembly 4 to have a certain amount of rotation, avoiding the problem of jamming the punch 4-3 caused by the installation deviation of the punch assembly 4 . Specifically, one end of the injection rod 1 is provided with a corresponding installation groove, and the other end of the connector 2 is arranged in the installation groove; as figure 2 As shown, the ...

Abstract

The invention relates to a variable-diameter high-seal pressure-shooting device. The variable-diameter high-seal pressure-shooting device comprises a pressure-shooting rod, a spherical connecting head, a cooling water conveying assembly and a punch assembly, wherein the spherical end of the spherical connecting head is arranged in one end of the punch assembly; the other end of the spherical connecting head is mounted in the end part at one end of the pressure-shooting rod; a pressure-shooting rod oil inlet cavity is arranged in the pressure-shooting rod; an oil inlet is formed in the pressure-shooting rod; a connecting head oil inlet cavity is arranged in the spherical connecting head; a punch assembly oil inlet cavity is arranged on the punch assembly; an oil outlet and an oil inlet are formed in the side wall of the punch assembly; and the oil inlet, the pressure-shooting rod oil inlet cavity, the connecting head oil inlet cavity, the punch assembly oil inlet cavity and the oil outlet sequentially communicate to form an oil inlet path. The variable-diameter high-seal pressure-shooting device has the beneficial effects that: the whole oil inlet path does not pass through an external adapter tube, and lubricating oil pours out from the inner part of the punch assembly to reduce friction resistance, so that the service life of the device is prolonged; and the punch assembly can have certain rotation amount through the spherical connecting head, so that the problem that a punch is blocked as a result of mounting errors of the punch assembly is avoided.

Description

technical field [0001] The invention relates to the technical field of feeding equipment for die-casting machines, in particular to a variable-diameter high-seal injection device. Background technique [0002] Conventional injection rods, connectors, and punches do not have any lubricating oil passages, and all rely on additional fuel injection devices beside the die-casting machine. The fuel injection device is not provided by the die-casting machine manufacturer, and all these costs are borne by the die-casting machine user. Solve (entrust external processing, or entrust the supplier to provide the feeding device to process. This costly processing is time-consuming and labor-intensive, which brings a lot of trouble to both suppliers.) After the punch impacts the aluminum water once, the lubricating oil will be burned at high temperature, and oil injection lubrication is required. The efficiency is greatly reduced, and the cost of lubricating oil cannot be ignored. On the c...
