Corner wrapping of head and tail board and its forming mold

Abstract

A headboard and tailboard wrapping angle and its forming mold, the headboard and tailboard wrapping angle includes a headboard and tailboard corner wrapping body, the headboard and tailboard corner wrapping body is divided into a first board body and a second board body, the first board There are several longitudinal reinforcing ribs and at least one transverse reinforcing rib on the back of the body and the second plate body, and the longitudinal reinforcing ribs on the first plate body correspond to the longitudinal reinforcing ribs on the second plate body one by one The longitudinal reinforcing rib is an integrated structure; the forming mold includes an upper mold, a lower mold, and a mold cavity formed by clamping the upper mold and the lower mold. The mold cavity includes the corresponding cavity of the first plate body, the corresponding cavity of the second plate body, and the longitudinal rib The corresponding cavity, the corresponding cavity of the transverse reinforcing rib, the corresponding cavity of the insert and the corresponding cavity of the right-angle flange, and the corresponding cavity of the transverse reinforcing rib are parallel to the vertical line; High, the insert is not easy to fall off, it is safe to use, it can be injection molded, the injection molding yield is high and the cost is low.

Description

technical field [0001] The invention relates to a wrapping angle of a bed head and tail board and a molding die thereof. Background technique [0002] Nursing beds are widely used in large and medium-sized hospitals, nursing homes, nursing homes, and newly built elderly apartments in my country. Nursing beds are equipped with head and tail boards. Usually, due to the needs of treatment, etc., it is necessary to move the nursing bed to other rooms, or move some treatment equipment in for use, so it is easy for the corners of the head and tail boards of the nursing bed to touch the wall or In the case of other things, in addition to damaging the headboard and footboard, it may also cause the headboard and footboard to be stuck on the wall and cannot move, which will delay the treatment of the patient. Therefore, in order to avoid the above-mentioned situation, usually there are The corner of the head and tail board can effectively avoid the above situation under the buffer an...

Problems solved by technology

[0003] The corners of the headboard and tailboards in the prior art are all formed by blow molding. Although the cushioning effect is good, the strength of the body of the headboard and tailboard corners after blow molding is limited due to the nut inserts used for installation. Low, the nut inserts are easy to disengage from the corner body of the headboard and footboard during installation and use, resulting in the inability to install the corner body of the headboard and footboard and fail to protect the headboard and footboard; and during use due to blow molding The strength of the formed corner body of the headboard and tailboard is not enough, and the body of the corner body of the headboard and tailboard is prone to dents or surface damage. Once the surface is damaged, because the wall thickness of the blow molded part is thin, the damaged surface is easy to Cutting the user or other people who pass by, so there is a big safety hazard, and the use safety is poor; some parts are injection molded, in order to facilitate demoulding and improve the success rate of demoulding, the head and tail of the bed The inner and outer surfaces of the panel corner body are smooth, and after this setting, although the strength is high, the inserts are not easy to fall off, but the amount of raw materials used is large, and because the thickness of the head and tail panel body is relatively large, it is difficult to The surface of the corner body of the headboard and tailboard is prone to shrinkage, and the yield is still relatively low, so the cost is high; moreover, the cushioning effect of the corner body of the headboard and footboard with a flat structure is poor during use, and the When it hits the wall or other things, it is easy to transmit most of the vibration directly to the head and tailboard and the nursing bed, which may cause secondary injury to the patient
