The invention discloses a method for making a mold for producing latex rubber condoms

- Jan 18, 2020-

Background technology:

Existing condoms are mostly made of latex, generally through latex polymerization, such as polybutadiene latex, butadiene latex.In order to achieve the solid content of 40% ~ 70%, the rubber particles are first agglomerated into larger particles, and then concentrated by the method similar to natural latex.In the process of condom processing, it is necessary to use the mold, and the existing condom mold is not convenient to demold, and the assembly is not convenient enough.


Technical realization elements:

In view of this, the purpose of the utility model is to provide a mold for the production of latex rubber condoms which is convenient for demodulation and easy for assembly.

In order to solve the above technical problems, the technical scheme of the utility model is:A latex condom production with mold, including convex mold and concave die, punch described in tubular, referred to the bottom of the punch with the boss, the boss described and punch forming, described of punch die set is located in the lateral, described in the punch on the top of the welding ring, described the retaining ring outer diameter and inner diameter of the die are equal, described are installed at the bottom of the concave die backplane, backplane described below the central connection with hydraulic cylinder, as described in central punch has a cavity, described on both sides of the cavity connected with stream crossings, described in the mouth cavity at the top of the installation of injection molding, injection nozzle including ontology, nuts and threaded pipe, described in the nut welding on the outside of the ontology,The threaded tube is welded to one side of the body.

The technical effect of the utility model is mainly reflected in the following aspects: the set hydraulic cylinder is connected with the bottom plate through the hydraulic rod, which can drive the die to move outside the punch, facilitating demoulding;The injection nozzle includes body, nut and threaded tube. The threaded tube is convenient for injection nozzle installation in the injection molding machine. The body can be inserted into the cavity, making assembly very convenient.

Technical features:

1. A latex rubber condom production mold is characterized by:Described including convex mold and concave die, punch a tubular, referred to the bottom of the punch with the boss, the boss described and punch forming, described of punch die set is located in the lateral, described in the punch on the top of the welding ring, described the retaining ring outer diameter and inner diameter of the die are equal, described are installed at the bottom of the concave die backplane, backplane described below the central connection with hydraulic cylinder, as described in central punch has a cavity, described on both sides of the cavity connected with stream crossings, described in the mouth cavity at the top of the installation of injection molding, injection nozzle including ontology, nuts and threaded pipe, described in the nut welding on the outside of the ontology, the threaded pipe welding at the side of the body.

2. According to the mold for the production of latex rubber condoms mentioned in claim 1, its characteristics are as follows: the outer side of the punch and the inner wall of the punch are less than 0.1mm apart.

3. According to the mold for the production of latex rubber condoms mentioned in claim 1, its characteristics are as follows: the outer wall of the retaining ring meets the inner wall of the concave mold.

4. According to the mold for the production of latex rubber condoms mentioned in claim 1, its characteristics are as follows: the hydraulic cylinder is connected with the bottom plate and installed with a bearing seat.

5. According to the milk rubber condom production mold mentioned in claim 1, its characteristics lie in: the punch is stainless steel punch.

6. According to the mold for the production of latex rubber condoms mentioned in claim 1, its characteristics are as follows: the front end of the body is arranged in a hemispherical shape.

7. The mold for the production of latex rubber condoms mentioned in claim 1 is characterized in that the body is stuck in the cavity.

Technical summary

The utility model discloses a latex condom production mold, including convex mold and concave die, punch described in tubular, referred to the bottom of the punch with the boss, the boss described and punch forming, described of punch die set is located in the lateral, described the top punch welding ring, described the retaining ring outer diameter and inner diameter of the die are equal, described are installed at the bottom of the concave die backplane, backplane described below the central connection with hydraulic cylinder, as described in central punch has a cavity, described on both sides of the cavity connected with stream crossings, described in the mouth cavity at the top of the installation of injection molding, injection nozzle including ontology, nuts and threaded pipe, described in the nut welding on the outside of the ontology,The threaded tube is welded to one side of the body.The mold is easy to demoulding and assemble.
