Specific implementation

[0020] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict, and the utility model will be further explained in detail in combination with the drawings and specific embodiments.

[0021] In the embodiment of the utility model, if there is a directional indication (such as up, down, left, right, front, back, etc.), it is only used to explain the relative position relationship, movement condition, etc. between components in a certain specific posture (as shown in the drawings), if the specific posture changes, the directional indication also changes accordingly.

[0022] In addition, in the utility model, if the description of "first", "second" and the like is only for the purpose of description, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one of the features.

[0023] Please refer to Figures 1-7 The face washing brush forming die of the embodiment of the utility model comprises a lower die, a top plate, a die core, a middle die and an upper die.

[0024] The face washing brush comprises a silica gel part and a conductive part, and is generally arranged on a massage head of a face massage instrument. The lower die is provided with a lower die groove, and the die core is arranged on the lower die groove. The middle die is provided with a middle die hole, and the upper die is provided with an upper die groove corresponding to the side of the conductive part of the face washing brush. The bottom of the die core is connected to the top plate through the lower die groove. The die core and the lower die groove, the middle die hole and the upper die groove which are sequentially stacked from bottom to top form a molding cavity corresponding to the face washing brush. After injection molding, the upper die and the middle die are removed, the die core is lifted, and the user can conveniently and quickly take down the injection molded face washing brush product.

[0025] The middle die is provided with a glue injection groove in communication with the molding cavity. The top of the die core is provided with a placement part for placing the conductive part. The placement part facilitates the user to quickly assemble the conductive part and place the conductive part to prevent deviation during injection molding, thereby improving the yield. The molding cavity and the die core have a plurality of groups. The upper die and the middle die are provided with handles on the side surfaces, which facilitates the user to remove the upper die and the middle die.

[0026] As an embodiment, the mold further comprises a U-shaped base, and the lower die is arranged on the base, and the top plate is located in the base.

[0027] As an embodiment, the base is further provided with a guide column for guiding the up-down movement of the top plate, which prevents the top plate from deviating during up-down movement, thereby preventing the die from colliding with the lower die groove and the middle die hole, protecting the mold and improving production efficiency.

[0028] As an embodiment, the base is further provided with a limiting part for limiting the die core. The limiting part prevents the die core from touching the side wall of the lower die groove during downward movement (i.e. during resetting), thereby protecting the mold and improving production efficiency. The limiting part is preferably a rod-shaped and detachable.

[0029] As an embodiment, the lower die is provided with a guide pin, and the top of the guide pin is protruding and limited, and the bottom of the guide pin is connected with a guide plate. In specific implementation, the guide plate is guided and limited by the lower half of the die core.

[0030] As an embodiment, the middle part of the placement part is provided with a groove, which improves the adhesion strength between the conductive part and the injection molded silica gel part.

[0031] The working principle of the utility model is as follows: the middle die is placed on the lower die, the conductive part is placed on the placement part on the top of the die core, and the upper die is covered; the silica gel is injected and vulcanized to form a face washing brush product; the upper die and the middle die are removed, the top plate is lifted, the die core is separated from the lower die, and the face washing brush product can be taken out.

[0032] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
