Abstract

The invention discloses a seat headrest vertical foaming mold. An upper mold and a lower mold are buckled together to form a headrest foaming cavity; a large cylinder is arranged at the top of a cylinder bracket, a small cylinder is arranged at the top of an upper mold insert, the left end and right end of the cylinder bracket extends downwards vertically so as to be fixedly connected with the left side wall and right side wall of the upper mold, the lower end of a piston rod of the large cylinder is connected with the upper mold insert which is internally provided with a vertically-through round hole, and the piston rod passes through the round hole; the top of a movable inserting block extends into a groove matched with the bottom of the upper mold insert, and the top of the movable inserting block and the top of the groove are fixed together by virtue of the magnetic force of a magnet; the upper mold insert drives the movable inserting block to move from top to bottom together; the upper mold insert extends into the top cavity of the upper mold, and the movable inserting block extends into the headrest foaming cavity. According to the seat headrest vertical foaming mold, material overflow and hard edges are avoided, the product stability is improved and the workload of operators is reduced.

Description

technical field

[0001] The invention relates to a foaming mold, in particular to a vertical foaming mold for a car seat headrest. Background technique

[0002] The existing car seat front and rear headrests are all made of horizontal foam foam, the cavity of the upper and lower molds is relatively shallow, and the mold line is long, which will cause overflow and hard edges; In addition to the gap between the upper and lower molds, there are also holes on the side of the mold for placing the headrest tube connecting the headrest and the seat. During the lifting process of the trolley, the hole for placing the headrest tube will also overflow. To sum up, the existing horizontal headrest foaming mold has overflow phenomenon, which is easy to produce hard edges, unstable product quality, and increases the workload of operators. Contents of the invention

[0003] The present invention improves on the above technical problems, and intends to provide a vertical foaming mold, whi...

Embodiment Construction

[0015] Below by embodiment and in conjunction with accompanying drawing, the present invention will be further described:

[0016] like figure 1 As shown, a seat headrest vertical foaming mold is mainly composed of a large cylinder 1, a small cylinder 2, a cylinder bracket 3, an upper mold insert 4, a movable insert 5, an upper mold 6, a lower mold 7, and a magnet 8 , large cylinder limit block 10, large cylinder guide column 11 and other components.

[0017] The upper mold 6 and the lower mold 7 are buckled together to form the headrest foaming cavity A, and the upper mold 6 and the lower mold 7 are arranged up and down to form a vertical headrest foaming mold.

[0018] The large cylinder 1 and the small cylinder 2 are vertical cylinders, the large cylinder 1 is installed on the top of the cylinder support 3, and the small cylinder 2 is installed on the top of the upper mold insert 4. The left and right ends of the cylinder support 3 extend vertically downwards and are fixe...
