Technical Field

[0001] The utility model relates to the technical field of molds, in particular to an airtight head mold. Background Art

[0002] A head mold generally refers to a mold in the shape of a human head. It is generally used to test the fit, sealing and other properties of masks or other facial products. It is an extremely important part in the testing of products such as masks. In the production of head molds, in order to ensure the integrity of the head mold, the blow molding process is generally used for one-piece manufacturing.

[0003] However, after the existing blow molding molds produce large batches of blow molding, some plastic residues may be left in the equipment. At this time, the equipment needs to be cleaned and maintained to ensure the quality and efficiency of the next production. However, manual cleaning is cumbersome and time-consuming, which increases the production interval and makes the overall efficiency insufficient. In view of this, we propose an airtight head mold.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) When the airtight head mold needs to be cleaned after the manufacturing of a batch is completed, the water flow can be transmitted to the interior of the water trough through the cooperation of the rear water pump and the transmission pipe, and then enter the interior of the dispersion tank in turn. Since the interior of the water trough is closed, the water pressure increases and enters the interior of the water outlet and uses the water pressure to squeeze open the sealing component, so that the water flow enters the interior of the forming cavity to complete the cleaning. Through the above structure, after a batch of manufacturing is completed, the interior of the forming cavity can be easily cleaned by cooperating with the water pump and the sealing component, and the sealing component can be used to seal the water outlet during normal use to avoid affecting the blow molding effect.

[0013] (2) The airtight head mold has an increased water pressure, and the water flow pushes the baffle to move. After the baffle moves, it drives the limit slide to move. After the limit slide moves, the reset plate stretches the spring synchronously. When the baffle moves, it drives the diverter block to move synchronously. After the baffle moves, the water outlet is connected to the inside of the forming cavity. After the water flow impacts, the semicircular groove forms a bowl shape, and then the residue around the baffle is flushed. At the same time, when it is necessary to adjust the size of the air outlet of the head mold, the number of annular plates can be increased or decreased. After the adjustment is completed, the annular plates are fixed by bolts. After molding, the protrusion at the air outlet position can be cut off. Through the above structure, when cleaning, the diverter block and the semicircular groove can be used to divert the water flow, thereby increasing the area flushed by the water flow, thereby improving the cleaning effect, and the size of the air outlet of the head mold can be adjusted by increasing or decreasing the number of annular plates.
