Problems solved by technology

When the angle between the core-pulling direction of the slider and the vertical direction of the mold opening is greater than or less than 30 degrees, the guiding force of the inclined guide column designed in the mold opening direction will be scattered, and the slider cannot move effectively
If the core pulling of the cylinder is designed in the direction of movement of the slider, the overall size of the mold will become larger, and the tonnage requirements of the mass-produced injection molding machine will increase, resulting in an increase in injection molding costs

Abstract

The invention discloses an injection mold with an oil cylinder slide block combined type core-pulling structure. The injection mold with the oil cylinder slide block combined type core-pulling structure comprises a fixed mold plate and a movable mold plate arranged below the fixed mold plate, wherein a fixed mold core is arranged in the fixed mold plate, a movable mold core is arranged in the movable mold plate, a product cavity and a slide block are arranged between the fixed mold core and the movable mold core, and a core-pulling mechanism is arranged in the movable mold plate. The core-pulling mechanism comprises an oil cylinder, an oil cylinder fixing screw and an oil cylinder stroke guiding block, the oil cylinder is connected with the oil cylinder stroke guiding block through the oil cylinder fixing screw, a first wear-resisting plate is installed on the oil cylinder stroke guiding block, a second wear-resisting plate is installed on the movable mold, a slide block stroke guiding block matched with the first wear-resisting plate is installed on the slide block, therefore, the size of the appearance of the mold is greatly reduced, and the mold space is saved.

Description

technical field [0001] The invention relates to an injection mold, in particular to an injection mold with an oil cylinder slider combined type core-pulling structure. Background technique [0002] Injection mold core pulling is generally realized by slider and inclined top movement. The movement of the slider generally uses the inclined guide post to transmit the guiding force. When the angle between the core-pulling direction of the slider and the vertical direction of mold opening is greater than or less than 30 degrees, the guiding force of the inclined guide column designed in the mold opening direction will be dispersed, and the slider cannot move effectively. If the core-pulling cylinder is designed in the direction of movement of the slider, the overall size of the mold will become larger, and the tonnage requirements of the mass-produced injection molding machine will increase, resulting in an increase in injection molding costs. [0003] Therefore, it is necessar...
