Mold device for making safety shoe

A mold device for making a safety shoe includes a last and a post secured on a board. The last includes a number of spacers and a number of cone-shaped supports formed on top for engaging with a protector and for spacing the protector from the last. Two mold pieces are pivotally coupled to the post and each includes a mold cavity for engaging with the last. A cover is pivotally coupled to the post. The spacers and the supports may space the protector from the last and the mold pieces and the cover for allowing the protector to be engaged in the safety shoe.

BACKGROUND OF THE INVENTION 
1. Field of the Invention 
The present invention relates to a mold, and more particularly to a mold 
device for making safety shoes. 
2. Description of the Prior Art 
Typical safety shoes comprise a toe protector engaged in the front portion 
of the shoe. However, it is difficult to engage the toe protector in the 
shoe such that the toe protector is typically secured in the shoe 
manually. 
The present invention has arisen to mitigate and/or obviate the 
afore-described disadvantages of the conventional mold devices for making 
safety shoes. 
SUMMARY OF THE INVENTION 
The primary objective of the present invention is to provide a mold device 
for molding the toe protector in the shoe. 
In accordance with one aspect of the invention, there is provided a mold 
device for making a safety shoe, the mold device comprises a board, a last 
and a post secured on the board, the last including an upper portion 
having a number of spacers and a number of cone-shaped supports for 
engaging with a protector and for spacing the protector from the upper 
portion of the last, the post including two side pivot shafts and an upper 
lateral pivot axle, a pair of mold pieces pivotally coupled to the post at 
the pivot shafts respectively, the mold pieces each including a mold 
cavity for engaging with the last, and a cover pivotally coupled to the 
post at the pivot axle. The spacers and the supports may space the 
protector from the last and the mold pieces and the cover for allowing the 
protector to be engaged in the safety shoe. 
Further objectives and advantages of the present invention will become 
apparent from a careful reading of a detailed description provided 
hereinbelow, with appropriate reference to accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
Referring to the drawings, and initially to FIGS. 1 to 3, a mold device for 
making a safety shoe in accordance with the present invention comprises a 
board 10 and a base 15 secured on the board 10 for supporting a last 11 
which includes a number of spacers 17 and a number of cone-shaped supports 
16 secured on the upper portion. A post 12 is extended upward from the 
board 10. Two mold pieces 20, 30 are pivotally coupled to the post 12 at 
two pivot shafts 13 for allowing the mold pieces 20, 30 to be rotated 
about the pivot shafts 13 respectively. The mold pieces 20, 30 each 
includes a mold cavity 21, 31 for engaging with the last 11 and the base 
15. A cover 40 is pivotally coupled to the post 12 at a pivot axle 14 for 
allowing the cover 40 to be rotated about the pivot axle 14. The cover 40 
includes a mold cavity 42 for engaging with the last 11. A gap may be 
formed between the last 11 and the mold pieces 20, 30 and the cover 40 for 
receiving injecting plastic materials. The cover 40 includes includes a 
port 41 for injecting plastic material into the mold device. 
As best shown in FIGS. 2 and 3, a toe protector 60 includes a cap shape and 
includes two holes 61 for engaging with the cone-shaped supports 16 and 
includes a bottom 62 for engaging with the spacers 17 which may space the 
bottom 62 from the upper portion of the last 11 for allowing the plastic 
materials to be injected into the gap formed between the last 11 and the 
bottom 62 of the toe protector 60. A plate 50 is engaged on the spacers 17 
and includes a number of holes 51 for engaging with the cone-shaped 
supports 16 such that the plate 50 may also be spaced from the upper 
portion of the last 11 for allowing the plastic materials to be injected 
into the gap formed between the last 11 and the plate 50 and such that the 
toe protector 60 and the plate 50 may be easily molded and engaged in the 
shoe 70, as shown in FIG. 4. The toe protector 60 and the plate 50 are 
preferably made of metal or similar strong relatively right material. 
Referring next to FIG. 5, the toe protector 60 and the plate 50 may be 
formed as an integral piece. In addition, one or more magnets 18 are 
embedded in the last 11 for attracting and for positioning the toe 
protector and the plate 50 in place. 
Accordingly, the mold device in accordance with the present invention 
includes a number of spacers and a number of cone-shaped supports for 
engaging with the toe protector and the plate and for spacing the toe 
protector and the plate from the last. 
Although this invention has been described with a certain degree of 
particularity, it is to be understood that the present disclosure has been 
made by way of example only and that numerous changes in the detailed 
construction and the combination and arrangement of parts may be resorted 
to without departing from the spirit and scope of the invention as 
hereinafter claimed.
