CUTTING APPARATUS FOR GATE OF INJECTION MOLDING PRODUCT

The present invention relates to an apparatus for cutting a gate of an injection product and more particularly to a device for cutting a gate part between each injection product and a runner in a quick, simple and precise manner in removing a runner connected between a plurality of injection products The present invention relates to a gate cutting apparatus for an injection product, which can reduce the labor force and improve the productivity and the quality of the injection product.

In general, small and medium-sized injection products are formed by forming a plurality of cavities in one injection mold to simultaneously produce several injection products by one injection process. The injection products produced by the above- A plurality of injection products 100 are connected to each other by a runner 110. A sprue 120 into which the molten resin flows is protruded from the runner 110, A gate 130 is formed between each injection product 110 and each injection product 100.

In addition, the injection product produced in the above-described manner is further subjected to a post-finishing operation. In the finishing operation, the gate portion between each injection product and the runner is cut and the gate point formed on the injection product is cleaned. On the other hand, And the runner can be collected and recycled so that the gate point protrudes from the surface of the injection product to obstruct assembly with other parts and hinds the appearance of the injection product, Of the total population.

However, in the related art, the above-mentioned mapping work is largely dependent on manual work, which makes the work inconvenient and makes it difficult to perform the quick work. This causes labor loss and productivity deterioration. In addition, the quality of the injection product varies depending on the skill of the operator It is difficult to produce an injection product of uniform quality.

On the other hand, an 'injection molding apparatus' for solving the problems of manual molding work by manual operation and automatically moving the molding operation of a highly precise injection product such as a smart phone has been proposed as a registered utility model No. 04000456. However, Injection molding means for eliminating the inner and outer gate points of the injection molding seated on the injection molding seating means, suction conveying means for sucking and rotating the injection molding from which the gate point has been removed, And a gate point sucking means for sucking the sucked material through vacuum suction on an outer gate point position removed by the ejection material throwing means. The structure is very complicated, Not only is it costly, but also And there is a problem that the gate cutting and the gate point mapping operation are made different from each other.
