Abstract

The invention provides a mold base pressing structure of an extruding machine. The mold base pressing structure comprises a tool rod and a mold base, wherein the back end of the tool rod is a clamping head protruding out of a column body in a radial direction; a cavity in which the clamping head can be accommodated is formed in the mold base; the front end of the mold base is an open end for holding the tool rod; an assembling hole through which the column body passes is formed in the open end in an axial direction; the connection between the assembling hole and the cavity is a clamping surface capable of propping against the clamping head; the cavity and the assembling hole at the open end extend upward to form a mounting opening; the clamping head and the column body can be assembled into and disassembled from the mold base through the mounting opening; a control piece is accommodated and fixed in the cavity at the fixed end of the back end of the mold base; the front end of the control piece is a pressing plate aligned with the clamping head; the pressing plate is positioned between the control piece and the clamping head; and through a power device of the control piece, the pressing plate is pushed forward or pulled backward, so that the clamping between the clamping head and the clamping surface is pressed or loosened. During pressing, the tool rod can be fixed on the mold base; and during loosening, the tool rod can be disassembled from or assembled into the mold base, so that the tool rod can be rapidly replaced and firmly mounted conveniently.

Description

technical field

[0001] The invention relates to extruder equipment, in particular to a mold seat pressing structure of a reverse extrusion metal extruder capable of quickly replacing tool rods. Background technique

[0002] The main body of the reverse extruder is generally composed of two stations, namely, the extrusion rod station and the push rod station. The function of the push rod station is that when the extruder changes the die, the push rod presses (holds) the die and then changes the die. The push rod station is required by the process. For example, when the car is stuffy, it is necessary to remove the push rod from the mold base and replace it with a cleaning sleeve. Tool rods such as the push rod and the cleaning sleeve are installed in the mold base. , The mold base can fix the push rod and clean the sleeve. However, in the prior art, the connection between the push rod and the mold base is generally a flange-type screw connection or a tie rod piercing connect...

Embodiment Construction

[0021] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the invention is capable of various changes in different embodiments without departing from the scope of the invention, and that the description and illustrations therein are illustrative in nature and not limiting. this invention.

[0022] Such as figure 1 Shown: the present invention provides a die base compression structure of an extruder, including a tool bar 1 and a die base 2 for fixing the tool bar 1, the tool bar 1 mentioned here is the existing reverse metal extrusion machine Tools such as push rod or cleaning sleeve, general main body is cylinder 12, for being able to cooperate mold base 2 to carry out compression, rear end is set as the chuck 11 that radially protrudes from cylinder 12.

[0023] The main technical idea of ​​the present invention is that, as figure 1 , image 3 , Figure ...
