Description

Automatic pouring gate shaping workstation that cuts of toilet lid

Technical Field

The utility model relates to a toilet bowl production facility technical field especially relates to an automatic runner plastic workstation of cutting of toilet lid.

Background

After the toilet lid is demolded from the injection molding machine, a sprue material remains between the rear portion of the upper lid and the rear portion of the seat ring, and the sprue material needs to be cut off when the upper lid and the seat ring are separated. In addition, because the seat ring and the upper cover are made of plastic materials, after the sprue material between the seat ring and the upper cover is cut off, the seat ring and the upper cover still have certain residual heat, are easy to tilt and deform, and are easy to be unmatched with the toilet seat, so the seat ring and the upper cover after the sprue material is cut off need to be shaped.

Traditional toilet lid runner material resection device adopts the manpower to rotate operating handle and drives the cutter and goes up and down to carry out the excision operation, arranges the tie point of seat circle and upper cover and runner material in under the cutter cutting edge, and the cutter moves down, separates seat circle and upper cover and runner material through the cutting edge to guarantee the parting surface as far as smooth. Based on the requirements, the cutter can only cut off the connecting point right below the cutter at one time. And in order to ensure the attractive appearance of the cut, the shearing surface must be close to one side of the product. Because the sprue material is respectively connected with the two ends of the upper cover and the seat ring, after one end of the sprue material is cut off, the upper cover or the seat ring needs to be rotated by 180 degrees by hands, so that the connecting point of the sprue material and the upper cover or the seat ring is positioned right below the cutter, and then the other end of the sprue material is cut off. On one hand, the sprue material cutting device is low in working efficiency, on the other hand, the sprue material is cut off through manual operation, the difference of cut surfaces is large, and products are easy to damage. In addition, the mode of pressing the weight block on seat circle and apron is mostly adopted in the plastic of traditional seat circle and upper cover to prevent the two and warp, however, this kind of mode needs the manual work to carry the weight block, consumes the manpower, and the weight block does not have limit structure moreover, shifts the landing easily, influences the plastic stability, influences production safety even.

Therefore, there is a need to develop an automatic gate cutting and shaping workstation for toilet covers.
