Problems solved by technology
This structure makes it difficult to demould the mold. The solution usually adopted by those skilled in the art is to use manual entry or adopt a mold structure that is drawn back, so as to overcome the technical problem of how to configure the mold as much as possible.
However, the manual insertion and back-drawing scheme will cause the manipulator to operate for too long or increase the number of typing
Moreover, this configuration method also needs to control the sequence of mold opening and closing, resulting in complex mold structure and prolonged molding cycle
This problem will seriously affect the speed of production processing

The invention discloses a ramp-roof multi-direction core pulling mechanism. The ramp-roof multi-direction core pulling mechanism comprises a sliding block base with a slope, an inclined sliding block,a stop block, a ramp-proof block and a drive device; a plane cushion platform is formed on the slope of the sliding block base, and the width of the plane platform is smaller than the width of the slope; the inclined sliding block is slidably connected to the slope, the stop block is slidably connected to the straight side wall of the inclined sliding block and configured to slide away from the slope relative to the inclined sliding block, and the plane cushion platform is configured to support the stop block; the inclined sliding block is provided with an inclined side wall located above thestraight side wall, the ramp-proof block is slidably connected to the inclined side wall, and the top face of the stop block forms a support for the bottom face of the ramp-proof block; and the drivedevice is configured to drive the sliding block base to move, and then the inclined sliding block slides towards the bottom of the slope. The top of the inclined sliding block and the top of the ramp-proof block form a mold core, and when the inclined sliding block slides downward along the slope, the ramp-proof block is configured to transversely move along the inclined side wall of the inclinedsliding block.
Description
technical field [0001] The invention belongs to the technical field of injection molding, and in particular relates to an inclined-top multi-directional core-pulling mechanism. Background technique [0002] In recent years, with the rapid development of consumer electronics, daily household appliances and other household products with relatively complex structures, in order to meet the requirements of reducing costs and improving user experience, more and more injection molding products or injection molding structural parts have been applied to the above-mentioned The product is being processed. The injection molding process can process more complex structures, and the processing process is easier to operate, and the materials used are usually lower cost materials such as injection molded plastics. However, in order to inject structural parts with relatively complex structures, it is inevitable that the mold structure will become complicated. [0003] Take the undercut str...
