Manufacturing method of glove mold for disposable nitrile medical gloves

- Oct 03, 2020-

Background technique:


The hand mold is a hand mold used to produce plastic gloves by dipping. The production process of various liquid-formed plastic gloves is: the ceramic hand mold is dipped with the plastic liquid material, and then dried and demolded. The hand molds used in production should be resistant to acid, alkali, chemical corrosion, and have a certain degree of thermal shock resistance.


The hand molds in the prior art are all made of ceramics. In the process of stripping, special stripping tools need to be used for stripping, resulting in high cost of production equipment, or manual stripping or manual stripping. In the process, it is easy to cause the problem of deformation or breakage of the glove.

Technical realization elements:


In view of the shortcomings of the prior art, the present utility model designs a glove mold in which the fingers at the end of the hand mold can be stretched and connected to gas. The separation of the glove and the hand mold can be achieved through the opening and lifting, and the film can be quickly released.


The technical scheme of the utility model is as follows:


A glove mold for disposable nitrile medical gloves, which includes a hand mold body with a hollow inner cavity, and is characterized in that: the hand mold body has at least one stretchable and breathable finger part, and The finger part includes a hollow finger part connected with the hand mold body. A step is formed on the outer surface of the end of the finger part. The side wall of the step is provided with a vent hole communicating with the inside of the finger part, and also includes a finger tip A concave matching cavity in the end surface of the fingertip part, the matching cavity is matched with the step, and the fingertip part is connected to the finger shaft part through a retractable elastic mechanism.


The elastic mechanism includes a connecting and fixing part connected to the hollow part of the finger, a through hole is provided on the axis of the connecting and fixing part, a spring is provided on the connecting and fixing part, and the other end of the spring is connected to the mating cavity of the fingertip part .


The elastic mechanism includes a connecting and fixing part connected to the hollow part of the finger part, a through hole is provided on the axis of the connecting and fixing part, a rubber elastic body is arranged on the connecting and fixing part, and the other end of the rubber elastic body is connected to the fingertip part. The matching cavity is connected.


The side wall of the step is provided with at least one protrusion or groove along the axial direction, and the side wall of the matching cavity is provided with a groove or protrusion that matches the protrusion or groove on the step.


An annular sealing gasket is provided on the step.


The body of the hand mold and the fingers are covered with expanded polytetrafluoroethylene film.


In summary, the utility model has the following beneficial effects:


The utility model improves the finger position of the hand model, and realizes the relative displacement between the fingertip part and the fingerstick part. When the two do not produce relative displacement, the fingertip part and the fingerstick part are connected together to form a complete finger When high-pressure gas is introduced from the outside, the gas enters the hollow fingertip through the inner cavity of the hand mold body, and acts on the fingertip. The stretchable elastic mechanism between the fingertip and the fingertip is stretched , The fingertip part and the fingerstick part are relatively displaced, so that the ventilation hole on the fingerstick part is connected, and the high-pressure gas flows out from the ventilation hole into the glove and the hand mold to realize the separation of the glove and the hand mold and realize the release of the film. There is no need for manual stripping, which improves production efficiency, and there is no need to set up additional stripping mechanisms, and the cost of the entire production line can also be reduced.
