Description

Technical Field

[0001] The invention relates to the technical field of precision manufacturing equipment, in particular to a demoulding mechanism for a high-quality medical drip funnel bottle. Background Art

[0002] In the medical field, a medical drip funnel bottle is a container used for medical drip infusion, usually made of soft plastic. It uses gravity to drip the liquid medicine from the bottle into the patient's vein. This bottle usually has scale markings so that medical staff can accurately measure and control the drip rate and dosage of the liquid medicine. In addition, the medical drip funnel bottle may also be equipped with accessories such as droppers, infusion tubes and infusion needles to facilitate medical staff to perform infusion operations.

[0003] In the production process of medical drip funnel bottles, the medical drip funnel bottles are usually attached to the injection mold after injection molding and cooling. At this time, they need to be demolded to complete the last step of production. Since their material is usually soft plastic, they are easily deformed during the demolding process, which leads to the unstable production quality of the medical drip funnel bottles. At present, the demolding method of such soft plastic products is usually direct air blowing or air blowing and manual removal. Since medical drip funnel bottles are generally provided with through holes, demolding cannot be completed by direct air blowing alone. Therefore, direct air blowing combined with manual removal by workers is usually adopted to prevent the medical drip funnel bottles from being damaged or deformed during demolding.

[0004] However, the existing direct blowing ejection method combined with manual removal by workers generally has the following problems: ① When demoulding and producing medical drip funnel bottles, more workers are required to manually remove the parts, which increases the labor costs of the enterprise; ② Direct blowing and ejection with workers manually picking up parts. Since the speed of workers manually picking up parts is not as fast as the automatic demoulding of the machine, the production cycle of the medical drip funnel bottle is increased, which increases the time cost of the enterprise; ③ Direct air blowing and ejection combined with manual part removal by workers requires increasing the product spacing to facilitate manual part removal by workers. However, increasing the spacing will increase the size of the mold with the same number of cavities, requiring a larger injection molding machine, which increases the company's production equipment costs.

[0005] ④ Direct blowing and ejection combined with workers' manual removal of parts may lead to unstable quality of medical drip funnel bottles after workers manually remove parts due to high labor intensity and easy fatigue. Summary of the invention
