Device to automatically place nut in mold

Abstract

The invention discloses a device to automatically place nuts in a mold. The device comprises a box body, a pressing plate, a driving mechanism, a feeding assembly and a control assembly; the feeding assembly comprises a feeding cylinder and a feeding push rod; the control assembly comprises an elastic part, a limiting sliding block and a sliding block push rod, wherein a horizontal inserting rod is arranged on the limiting sliding block; and the device is provided with a longitudinally-arranged feeding opening and a horizontally-arranged feeding through hole, the nuts which need to be fed intoa mold cavity are arranged in the feeding opening in parallel and in a single row from bottom to top, the driving mechanism drives the feeding push rod and the sliding block push rod to move in the same direction, the feeding push rod slides in the feeding through hole to push materials, and the sliding block push rod and the horizontal inserting rod are used for intermittently opening or closingthe feeding opening. The device is simple in structure and can be installed on an injection mold, so that the function that the nuts are automatically placed in the mold cavity is realized, the product qualification rate and the production efficiency are improved, the working intensity of an operator is relieved, the potential safety hazards are avoided, and the production period is shortened.

Description

technical field [0001] The invention relates to the field of automatic production of injection molded parts, in particular to a device for automatically placing nuts in a mold. Background technique [0002] Nuts are now used in many plastic products. For example, the plastic case of a laptop computer and the motherboard need to be fixedly connected by nuts and screws. During production, the nuts need to be melted into the plastic case to fix the nut to the plastic case. Combine, and then fix the motherboard to the plastic case. [0003] At present, there are two ways to implant nuts into plastic parts: one is to manually bury the nuts in the plastic mold, and then injection mold the plastic parts; in the file. There are many disadvantages in the traditional production method: (1) The manual operation is cumbersome and time-consuming, which prolongs the processing cycle of a unit product; (2) The precision of the embedding position is low, and there is a hidden danger of mi...
