Description

Technical Field:

[0001] The utility model relates to the technical field of glove mold equipment, and more specifically to a corrosion-resistant hand mold. Background Art:

[0002] Most of the existing hand molds for producing disposable gloves made of materials such as nitrile, PU, rubber, PVC, and waterborne polyurethane are made of ceramic materials, that is, ceramic hand molds; a small number use metal hand molds, such as titanium alloy metal hand molds.

[0003] For the mold of producing disposable gloves, in order to heat up quickly and achieve the goals of saving energy and improving efficiency, the glove mold is made hollow as much as possible, and the wall thickness of the glove mold is made as thin as possible, so that less heat is absorbed and the glove mold heats up quickly.

[0004] However, the glove mold for producing nitrile latex must go through pickling, alkali washing, and chlorine washing. Therefore, the metal hand mold must be resistant to acid corrosion, alkali corrosion, and chlorine corrosion. However, the existing metal hand mold has no protective structure on its entire outer wall surface, and since its interior is hollow and communicates with the outside, there is also no protective structure on its inner wall surface, so that neither the entire outer wall surface nor the inner wall surface of the hand mold has the functions of acid corrosion resistance, alkali corrosion resistance, and chlorine corrosion resistance;

[0005] Therefore, when it is used, it is first corroded by chlorine, causing pinhole-sized holes to appear on its surface. During pickling and alkali washing, it is further corroded by acid and alkali, making the holes larger and larger. Finally, the whole is damaged and cannot be used, and its service life is low. Content of the Utility Model:

[0006] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a corrosion-resistant hand mold. It covers the cavity of the main shell above it through a sealing plate, so that chlorine, acid liquid, and alkali liquid cannot enter, ensuring the internal protection effect. At the same time, corrosion-resistant coatings are applied on the bottom surface of the sealing plate, the inner wall surface of the arm section below the sealing plate, the surface of the fixing plate, and the outer wall surface of the arm section, greatly reducing the probability of its being corroded and improving the service life.

[0007] The solution of the utility model to solve the above technical problems is:

[0008] A corrosion-resistant hand mold, comprising a hand mold body which is a main housing with a cavity inside. It includes a palm section and an arm section. A fixing plate is welded and fixed at the bottom of the arm section. A plug-through groove is formed in the middle of the fixing plate. A sealing plate is installed in the lower part of the arm section. The outer side wall of the sealing plate is welded and fixed on the inner side wall of the lower part of the arm section. The sealing plate covers the cavity of the arm section above the sealing plate. The sealing plate can, firstly, prevent the convection of the temperature between the inside of the main housing above the sealing plate and the air, improving the heat preservation performance of the hand mold body. Secondly, it can prevent corrosive substances such as acids, alkalis, and chlorine gas in the external environment from coming into contact with the inside of the hand mold body, improving its anti-corrosion effect and greatly increasing the service life of the hand mold.

[0009] A protective layer is provided on the outer side wall of the arm section. Corrosion-resistant coatings are applied on the outer side wall of the arm section, the bottom surface of the sealing plate, the inner wall surface of the arm section below the sealing plate, the outer wall surface and the inner wall surface of the fixing plate of the arm section.

[0010] The corrosion-resistant coating is a PVC dip coating layer, and the protective layer is a nickel layer which is electroplated on the outer side wall of the arm section by electroplating.

[0011] A counterweight is inserted into the arm section from the middle to the palm section. The counterweight is inserted into the middle through holes of a plurality of metal sheets. The outer side wall of the counterweight is welded and fixed on the inner side wall of the middle through holes of the metal sheets. The outer side wall of the metal sheets is welded and fixed on the inner side wall of the arm section. The lowermost metal sheet is above the sealing plate.

[0012] Upward vertically extending convex positioning plates are formed on the top surfaces at the two long side walls of the plug-through groove.

[0013] The outstanding effect of the present utility model is:

[0014] Compared with the prior art, the outer surface of its arm section is electroplated with a nickel layer, improving the anti-corrosion effect. At the same time, the cavity of the main housing above it is covered by a sealing plate, so that chlorine gas, acid liquid, and alkali liquid cannot enter, ensuring the internal protection effect. At the same time, corrosion-resistant coatings are applied on the outer side wall of its arm section, the bottom surface of the sealing plate, the inner wall surface of the arm section below the sealing plate, the outer wall surface and the inner wall surface of the fixing plate of the arm section, further reducing the probability of its being corroded and increasing the service life.

[0020] Embodiment, see Figures 1 to 4 As shown, a corrosion-resistant hand mold includes a hand mold main body 10. The hand mold main body 10 is a main housing with a cavity inside, which includes a palm section 12 and an arm section 11. A fixing plate 13 is welded and fixed at the bottom of the arm section 11.

The corrosion-resistant coating 2 is a rubber sheet with a thickness within 3 CM. It can have different colors to distinguish different models of hand molds for color differentiation.

[0024] Furthermore, the protective layer 1 is a nickel layer, which is plated on the outer wall of the arm section 11 by electroplating, and its thickness is 15 - 50 um. The purpose is to better improve the corrosion resistance of the hand mold.

[0025] Furthermore, the palm section 12 is formed by splicing and welding two semi - palm - shaped shells 121. Forming them in two pieces and then welding them together has low cost and is convenient for manufacturing.

[0026] Furthermore, the arm section 11 is a tube body formed by tube expanding, and its top end is fixedly welded to the bottom end of the palm section 12.

The counterweight 30 is inserted into the middle through - holes of multiple metal sheets 31. The outer wall of the counterweight 30 is fixedly welded to the inner wall of the middle through - hole of the metal sheet 31. The outer wall of the metal sheet 31 is fixedly welded to the inner wall of the arm section 11. The metal sheet 31 above it is at the bottom end of the palm section 12, and its outer wall is fixedly welded to the inner wall of the bottom end of the palm section 12.

[0029] Furthermore, upward - vertically - extending convex positioning plates 132 are formed on the top surfaces at the two long - shaped side walls of the insertion through - slot 131.
