Forming device for manufacturing high-sealing child guardrail inflatable film by using TPU material

Abstract

The invention provides a forming device for manufacturing a high-sealing child guardrail inflatable film by using TPU material. The forming device comprises a forming mold head and a cooling device; the forming mold head sequentially comprises an upper mold body, a gas collecting ring, a lower mold body and a mold opening from top to bottom, an annular forming opening is formed in the end face ofthe mold opening, and a through hole is formed in the middle of the mold opening; the cooling device comprises a large cooling water tank, a supporting frame, at least two parallel positioning columns, a small cooling water tank, a positioning ring and cooling cloth; a plurality of ice water injection pipes are connected to the peripheral wall of the small cooling water tank, an annular groove isformed in the interior of the small cooling water tank in the circumferential direction, the through hole is formed in the center of the annular groove, the positioning ring is located at the position, corresponding to the through hole, of the top of the annular groove, the cooling cloth is round, one end of the cooling cloth penetrates through the through hole to be fixedly connected with the positioning ring, and the other end of the cooling cloth penetrates through a gap between the two positioning columns. The forming and cooling are convenient to control, the radial size adjustment is convenient, and rolling and packaging can be facilitated.

Description

technical field [0001] The invention relates to the technical field of production of children's products, in particular to a molding device for making an inflatable film for a high-sealing children's guardrail using TPU material. Background technique [0002] Existing guardrails for children are generally made of hard plastic, which has potential safety hazards. Therefore, an inflatable child guardrail has been born. This inflatable child guardrail has an inflatable film, which is inflated during use, which can improve the cushioning effect and improve safety. However, the manufacture of this kind of air-filled film is cumbersome, and the forming and cooling are not easy to control, especially its radial dimension is difficult to control, and it is not convenient for winding and packaging after forming and cooling. Contents of the invention [0003] In view of this, the present invention provides a molding equipment that uses TPU material to make a high-tightness inflatab...
