Background

Polystyrene molds are commonly known as lost foam. The conventional casting enterprises need to process the polystyrene mold by a numerical control milling machine before casting, need to change milling cutters in a trivial way in the processing process, such as a plain milling cutter, a chamfer cutter, an end milling cutter, a conical cutter, an arc cutter and the like, and only three types of the plain milling cutter, the chamfer cutter and the end milling cutter are commonly used, but the milling cutters need to be arranged in multiple sections and replaced in a trivial way in the processing process, so that the labor and the time are wasted, and the efficiency is low. Therefore, a combined milling cutter is needed to replace the existing flat milling cutter, chamfer cutter, end milling cutter and multi-segment control.

A polystyrene mold combined milling cutter is characterized by comprising a cutter handle, a flat milling cutter blade, a chamfering cutter frame, a chamfering cutter blade, a vertical milling cutter frame, a vertical milling cutter blade, a screw hole and a screw rod;

the tool holder is cylindrical, the upper part of the tool holder is vertically arranged in the numerical control milling machine spindle caliper, and the center of the bottom of the tool holder is provided with a cylindrical screw hole;

the flat milling blade is rhombic and horizontally arranged at the bottom of the cutter handle, and a circular hole is formed in the center of the flat milling blade;

the chamfering tool rest is in a cylindrical shape with a large upper part and a small lower part and is vertically arranged at the bottom of the flat milling blade, a circular through hole is vertically arranged in the center, and the side surfaces of the two sides are obliquely and symmetrically welded with a rectangular chamfering blade respectively;

the vertical milling cutter frame is cylindrical and is vertically arranged at the bottom of the chamfering cutter frame, rectangular vertical milling cutter pieces are respectively welded on the side surfaces of two sides in an inclined and symmetrical mode, and a cylindrical screw rod is vertically arranged in the center of the upper portion and penetrates through center holes of the chamfering cutter frame and the flat milling cutter pieces to be meshed with a screw hole.

Has the advantages that: the conventional casting enterprises need to process the polystyrene mold by a numerical control milling machine before casting, need to change milling cutters in a trivial way in the processing process, such as a plain milling cutter, a chamfer cutter, an end milling cutter, a conical cutter, an arc cutter and the like, and only three types of the plain milling cutter, the chamfer cutter and the end milling cutter are commonly used, but the milling cutters need to be arranged in multiple sections and replaced in a trivial way in the processing process, so that the labor and the time are wasted, and the efficiency is low. When the polystyrene mold combined milling cutter is used, calipers of a spindle of a numerical control milling machine drive a cutter handle to rotate at a high speed, the cutter handle simultaneously drives a flat milling blade, a chamfering blade and an end milling blade to synchronously rotate, and planes, chamfers and vertical surfaces of a polystyrene mold are milled at one time according to a set route.

Detailed Description

The shape and structure of the present invention will be described in detail with reference to the accompanying drawings and the reference numerals:

a polystyrene mold combined milling cutter is characterized by comprising a cutter handle 1, a flat milling cutter piece 2, a chamfering cutter rest 3, a chamfering blade 4, an end milling cutter frame 5, an end milling cutter piece 6, a screw hole 7 and a screw rod 8;

the tool shank 1 is cylindrical, the upper part of the tool shank is vertically arranged in the numerical control milling machine spindle caliper, and the center of the bottom of the tool shank is provided with a cylindrical screw hole 7;

the flat milling blade 2 is rhombic and horizontally arranged at the bottom of the cutter handle 1, and a circular hole is formed in the center of the flat milling blade;

the chamfering tool rest 3 is in a cylindrical shape with a large upper part and a small lower part and is vertically arranged at the bottom of the flat milling blade 2, a circular through hole is vertically arranged in the center, and the side surfaces of two sides are obliquely and symmetrically welded with a rectangular chamfering blade 4 respectively;

the vertical milling cutter frame 5 is cylindrical and is vertically arranged at the bottom of the chamfering cutter frame 3, the side surfaces of two sides are obliquely and symmetrically welded with a rectangular vertical milling cutter piece 6 respectively, the center of the upper part is vertically provided with a cylindrical screw rod 8, and the screw rod 8 penetrates through the chamfering cutter frame 3 and the center hole of the flat milling cutter piece 2 to be meshed with the screw hole 7.

When the polystyrene mold combined milling cutter is used, a worker firstly fixes a polystyrene plate to be carved on a rack of a numerical control milling machine, a three-dimensional graph of the mold is edited by a computer of the numerical control milling machine, then the numerical control milling machine is started to enter a working state, a main shaft of the numerical control milling machine drives calipers and the combined milling cutter to rotate clockwise at a high speed, a longitudinal and transverse movable arm of the numerical control milling machine drives the main shaft to move longitudinally and transversely according to a set program, a flat milling blade horizontally cuts the upper surface of the edge of the polystyrene plate when the combined milling cutter moves, a vertical milling blade vertically cuts the side surface, a chamfering blade synchronously cuts the right-angled part at the upper part at one time, the worker pauses the numerical control milling machine after the peripheral and middle holes of the polystyrene plate are cut, then turns over the polystyrene plate as required and then fixes the polystyrene plate again, and the worker, the numerical control milling machine cuts the polystyrene board according to the steps, if the special-shaped milling cutter needs to be replaced midway, the numerical control milling machine can be started after being suspended until the polystyrene board is cut and becomes the die.
