Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a convenient demoulding automobile seat mould. Background Art

[0002] The automobile seat mold is an injection mold used for injection molding seat materials, and then splicing to form an automobile seat. After the current automobile seat mold is injection molded, the material will be adhered in the mold due to heating and cooling, and it is not easy to remove. The method to solve the material adhesion is mostly to spray a release agent on the mold surface before the thermoplastic mold, so that the automobile seat mold can be easily removed after the thermoplastic mold is completed; for example, the Chinese utility model patent with the authorization announcement number CN217943987U discloses an automobile seat mold that is easy to demold quickly, including a main body component, including a base, a lower mold and an upper mold, the lower mold is fixed to the top of the base, the upper mold is arranged on the top of the lower mold, and the demolding component is arranged on one side of the base, including a storage part, a transmission part, an output part and a bearing part, the storage part is fixed to one side of the base, one end of the transmission part is fixed to the storage part, the output part is fixed to the other end of the transmission part, and the bearing part is fixed to one side of the base; however, demolding using only a release agent has the following defects:

[0003] After injection molding is completed, there is no gas inside the mold. If the release agent is directly injected at this time, it is difficult for the release agent to penetrate into the contact position between the molded plastic and the cavity. When the upper mold is opened, the air pressure will cause pulling force on the molded plastic, which is easy to cause damage to the molded plastic and poor demolding effect.
