Core Pulling Device

Abstract

The invention provides a core pulling device, which comprises a vertical fixed block, a horizontal guide wear-resistant block and a sliding block arranged on the guide wear-resistant block. Specifically, an oil cylinder is disposed on the fixed block and in fixed connection with the sliding block, and drives the sliding block to slide on the guide wear-resistant block; the sliding block is internally provided with an arc core pulling block, a first direction core pulling block embedded in the arc core pulling block, a second direction core pulling block connected to the first direction core pulling block, and a third direction core pulling block passing through the first direction core pulling block and the second direction core pulling block; a pull block is fixed on the sliding block, and drives the first direction core pulling block to do core pulling motion in the arc core pulling block, the first direction core pulling block drives the second direction core pulling block to do core pulling motion in the arc core pulling block, and drives the third direction core pulling block to do core pulling motion in the arc core pulling block. The core pulling device provided by the invention achieve effective molding of an arc upside-down product, no parting line exists at an upside-down position of a product, and the product molding quality is high.

Description

technical field [0001] The invention relates to the technical field of mold design, and more specifically, relates to a multi-directional core-pulling device in an arc axis. Background technique [0002] With the development of society and prosperity, people's demand for the quality of various electronic products is getting higher and higher. In order to meet people's needs for various functions of electronic products, the product structure is becoming more and more complex. [0003] At present, when the product has a large undercut, it is usually formed with a large-angle inclined top. The forming process must meet the constraints of the inclined top retreating without interfering with the product structure, and the product does not clamp the inclined top and retreat. For products with relatively large undercuts , the above conditions cannot be satisfied. In addition, the use of inclined top molding will also lead to the appearance of inclined top parting lines on the surf...
