Detailed Description
It should be noted that, without conflict, the embodiments of the present utility model and features of the embodiments may be combined with each other, and the present utility model will be further described in detail with reference to the drawings and the specific embodiments.
In the embodiment of the present utility model, if there is a directional indication (such as up, down, left, right, front, and rear … …) only for explaining the relative positional relationship, movement condition, etc. between the components in a specific posture (as shown in the drawing), if the specific posture is changed, the directional indication is correspondingly changed.
In addition, the description of "first," "second," etc. in this disclosure is for descriptive purposes only and is not to be construed as indicating or implying a relative importance or implying an indication of the number of features being indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature.
Referring to fig. 1 to 7, the liquid silicone eye-mask mold of the embodiment of the utility model is composed of an upper mold, a middle mold and a lower mold which are sequentially arranged from top to bottom.
The liquid silica gel eyeshade mould is provided with a mould cavity corresponding to the eyeshade. In particular, a plurality of mold cavities may be provided.
The upper die is provided with a glue injection hole, and the middle part of the front side of the top of the die cavity is communicated with the glue injection hole. The middle of the top front side of the mold cavity corresponds to the middle of the top front side of the eye shield product (corresponds to the position of the eyebrow). In the concrete implementation, the middle die is provided with a glue injection groove, and the glue injection hole is communicated with the die cavity through the glue injection groove.
And a glue overflow groove A is formed between the middle die and the lower die. The glue overflow groove A is communicated with the middle of the bottom rear side of the die cavity. The middle of the bottom rear side of the mold cavity corresponds to the middle of the bottom rear side of the eye shield product (namely corresponds to the nose bridge).
According to the utility model, the symmetry of the eyeshade is utilized, and the glue inlet position (such as the position A in fig. 7) and the glue overflow position (such as the position B in fig. 7) of the die cavity are respectively arranged at the position of the eyebrow and the position of the bridge of the nose, so that the liquid silica gel entering from the glue injection hole flows to two sides after entering the die cavity, and finally is converged at the position of the bridge of the nose, and no air trapping and welding marks are caused. The glue overflow groove A is arranged on the middle die or the lower die, preferably on the middle die.
As one implementation mode, a glue overflow groove B is formed between the upper die and the middle die, and the glue overflow groove B is communicated with the middle of the rear side of the top of the die cavity. The glue overflow groove A and the glue overflow groove B are arranged at the front and back positions of the eyeshade, so that glue injection is more convenient. And the excessive glue quantity is added at the positions of the glue overflow groove A and the glue overflow groove B, and the glue is directly torn off after being molded, so that the appearance of the eye mask product is not affected.
As an implementation mode, the upper die, the middle die and the lower die are all provided with positioning holes. The positioning holes on the upper die, the middle die and the lower die are vertically distributed (namely, vertically communicated, so that the positioning column is convenient to insert) respectively, and a user can conveniently position and fix the die. The upper die, the middle die and the lower die are all provided with 4 positioning holes.
As an embodiment, the bottom edge of the upper die and the top edge of the lower die are provided with steps. The step user separates the middle die from the upper die and the lower die, so that the demolding is convenient, and the molded silica gel eyeshade can be taken out of the die cavity after the middle die is taken down. The steps of the upper die and the lower die are 4, and are distributed at 4 angles.
As one embodiment, the side surface of the middle die is provided with a pin hole groove, and a pin hole is arranged in the pin hole groove. The pin hole groove is convenient for fixing and demoulding the middle die. The number of the pin hole grooves is two, and the pin hole grooves are arranged on two sides of the middle die.
Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the utility model as defined by the appended claims and their equivalents.
