Description

Technical Field

[0001] The utility model relates to the technical field of automation, and specifically relates to a simple injection molding gate cutting mechanism. Background Technique

[0002] At present, the middle frames of mobile phones are divided into metal or plastic frames, which provide structural support for mobile phones and protect internal components. For plastic middle frames, injection molding is a fast and cost-effective manufacturing method. Through injection molding, middle frames with complex shapes can be produced, and injection molding gates will be left on the injection-molded mobile phone middle frames, which need to be sheared off later.

[0003] At present, most injection molding gates on the market are removed by shearing. Obviously, it is impossible to achieve the cutting effect for the columnar gates formed in the middle of the mobile phone middle frame by the shearing method. For the cutting of such gates, at present, manual milling on a milling machine is used, which consumes manpower and material resources and has low efficiency, and can no longer meet the current high-efficiency requirements.

[0010] Optionally, milling cut openings are opened on the surfaces of the fixing plate and the positioning fixture.

[0011] The utility model provides a simple injection molding gate cutting mechanism, which has the following beneficial effects:

[0012] The simple injection molding gate cutting mechanism drives the high-speed spindle on the lifting slide table to rise to the columnar gate of the product through a servo motor driving a driving lead screw, drives the milling cutter to rotate at a high speed, and mills off the columnar gate, so as to achieve the purpose of automatically milling and cutting the injection molding gate, which saves time and effort, greatly avoids the situation of manually using a traditional milling machine for milling and leveling, consuming manpower and material resources, effectively improves its efficiency, and has a simple structure and is convenient for manufacturing and installation.
