Bottle preform injection molding model machining tool and method for machining model

Abstract

The invention relates to a bottle preform injection molding model machining tool. The bottle preform injection molding model machining tool comprises a clamping part, an overhanging part, a tool bit and a blade which are sequentially connected, wherein the section of the clamping part is a circle, the diameter of the clamping part is 16 mm, the length of the clamping part is 70 mm, the section ofthe overhanging part is an oval with the long axis being 15 mm and the short axis being 10.5 mm, the maximum length of the overhanging part is 55 mm, and the distance from the tail end of the overhanging part to the front end of the blade is 80 mm; and the tool bit is welded to the front end of the overhanging part, the blade is installed at the front end of the tool bit, and the distance betweena tool nose of the blade and the axis of the tool is 5.25 mm. By using the machining tool, a ball head part of a whole cavity can be completely turned by using a turning tool, so that the machining procedure of a machining center is omitted, and the machining time is greatly saved. Meanwhile, the coaxiality error (the precision is 0.005mm) generated by two times of clamping can be reduced, the grinding allowance of an universal grinder during finish machining is further reduced, the machining time is saved while the working procedures are reduced, the cost consumed by the tool is reduced, andtherefore the efficiency of the whole technological process is improved.

Description

technical field [0001] The invention relates to a model processing tool, in particular to a lathe tool for processing a deep ball head in a cavity and a method for processing a model. Background technique [0002] Preform injection mold cavity is a very important part in the whole set of preform injection mold, especially the inner molding part, which requires high precision, special structure and long processing time. [0003] In the prior art, when semi-finishing the forming part, due to its special structure and precision requirements, the processing is limited. The main processing difficulty lies in the ball head part deep in the cavity. The cavity is deep and small, and the standard inner hole turning tool It can only process the first half, and cannot reach the ball head at all. Although there are many profiling turning tools on the market that can process the ball head, such as Sandvik’s medical boring bar, Mitsubishi’s damping boring bar and other standard tools, but...

Problems solved by technology

Although this method can complete the processing of the ball head, the double clamping of the two processes leads to a large coaxiality error, which increases the processing allowance of the subsequent universal mill and virtually increases the processing time.
