Manufacturing method of mold for producing nitrile gloves with convenient demolding

- Aug 13, 2020-

Background technique:


With the rapid development of the economy, people's self-protection awareness has gradually increased, and the use of disposable gloves has increased rapidly. Among them, nitrile gloves are the most popular because they have excellent physical properties, superior elasticity, and comfortable wearing. It also has outstanding chemical resistance, and it is rare for the wearer to have skin allergies. Therefore, nitrile gloves are widely used in all walks of life. In the process of glove production, casting is required, that is, die casting Forming, but the finger gap between the fingers of the existing mold is not smooth, and it is difficult to demold after the pressure is completed, which will greatly affect the production quality and the production rate, and greatly increase the production cost.

Technical realization elements:


In view of the above-mentioned shortcomings in the prior art, the purpose of the present invention is to provide a mold for the production of nitrile gloves that is convenient for demolding and does not produce finger seams.


The technical solution adopted by the utility model to achieve the above-mentioned purpose is a mold for the production of nitrile gloves with convenient demolding, which includes a left mold, a main mold, and a right mold. The main mold is configured in a human finger and wrist structure, and includes The little finger, ring finger, middle finger, index finger, thumb, wrist and arm, the bottom of the main mold is provided with a high-pressure blowing pump, and the blowing port of the high-pressure blowing pump is set on the bottom edge of the main mold and is connected to the arm of the main mold It is arranged in a vertical structure, the left mold is hingedly connected with the top end of the right mold, and the die-casting grooves of the left mold and the right mold are matched with the main mold, and both are arranged in a human finger and wrist structure. The length of the bottom of the main mold is greater than the length of the bottom of the left and right molds.


The little finger, ring finger, middle finger, index finger, thumb, wrist and arm on the main mold are all seamlessly connected.

Multiple sets of reinforcing ribs are arranged in the main mold.

The angle between the little finger, ring finger, middle finger, and index finger on the main mold is greater than 20° and less than 30°.

The angle between the thumb and the index finger on the main mold is greater than 70° and less than 80°.

The hinge joint of the left mold and the right mold is provided with a shock-absorbing pad.


The beneficial effect of the utility model: no finger joints will be produced, because the little finger, ring finger, middle finger, index finger, thumb, wrist and arm on the main mold are seamlessly connected, and the left mold and the right mold are used. The main mold is die-casted, that is, the left mold and the right mold are injected by the injection molding machine. After the injection is completed, the left mold and the right mold are die-casted, so that the raw materials for injection are die-cast into the shape of the main mold, that is, the shape of the glove. Finger cracks occur after die-casting; it is convenient to demold. After die-casting, open the left and right molds. At this time, the gloves will stick to the main mold and turn on the high-pressure blowing pump on the main mold. The blowing port of the air pump is set at the bottom edge of the main mold and is perpendicular to the arm of the main mold. Therefore, the blowing port blows the glove opening with high pressure to separate the main mold from the main mold to achieve the effect of convenient demolding.

Technical characteristics:


1. A mold for the production of nitrile gloves with easy demolding, comprising a left mold, a main mold, and a right mold, characterized in that: the main mold is arranged in a human finger and wrist structure, and includes the little finger, the ring finger, the middle finger, and the index finger , Thumb, wrist, and arm, the bottom of the main mold is provided with a high-pressure blowing pump, and the blowing port of the high-pressure blowing pump is arranged at the bottom edge of the main mold and arranged in a vertical structure with the arm of the main mold, the The left mold is hingedly connected with the top end of the right mold, and the die-casting grooves of the left mold and the right mold are configured to match with the main mold. Both are arranged in a human finger and wrist structure. The bottom of the main mold is longer than the The bottom length of the left mold and the right mold.


2. A mold for the production of nitrile gloves with easy demolding according to claim 1, characterized in that: the little finger, ring finger, middle finger, index finger, thumb, wrist and arm of the main mold are not Sewing connection.


3. A mold for the production of nitrile gloves with convenient demolding according to claim 1, wherein multiple sets of reinforcing ribs are provided in the main mold.


The mold for producing nitrile gloves with easy demolding according to claim 1, wherein the angle between the little finger, ring finger, middle finger, and index finger on the main mold is greater than 20° and less than 30°.
