MOLD FOR MAKING SHOES FIELD OF THE INVENTION The present invention relates to a mold assembly for making shoes and more particularly, to a mold assembly having positioning plates on two side molds so as to 5 effectively prevent the material from leakage. BACKGROUND OF THE INVENTION A conventional mold assembly for making shoes is shown in Fig. 1 and generally includes a bottom mold 1 which includes a cavity 4 defined in a top thereof, two side molds 2 which are able to move toward the bottom mold 1, and a top mold 3 0 which is positioned between the two side molds 2 and closes the cavity 4. Material for the shoe sole such as rubber is injected into the cavity 4 which is then solidify and forms the shoe sole. However, there is an inherent problem of difficult for precisely positioning the side molds and the top mold 3, so that the material easily leaks from gaps between the side molds 2 and the top mold 3, or the material cannot be evenly 5 filled in the cavity 4. Either of the two situations requires extra labor time to remove the surplus material or even discard the unsatisfied product that the rubber is not evenly spread. Besides, the shoe sole made by the conventional shoe mold assembly cannot have patterns on the peripheral surface thereof and does not attract consumers' attentions. 10 The present invention intends to provide a mold assembly for making shoes and the mold assembly includes two positioning plates on top surfaces of the two side 1 molds which seal the gap between the top mold and the side molds so that no material leaking from the gap. SUMMARY OF THE INVENTION The present invention relates to a mold assembly for making shoes and the 5 mold assembly comprises a bottom mold having a cavity defined in a top thereof, two side molds movably connected to two sides of the bottom mold and a top mold removably located on a top of the bottom mold. The two side molds include multiple notches defined in a top of an inside thereof so as to be connected with two positioning plates which are located on two respective top surfaces of the two side molds. Each of 0 the two positioning plates includes multiple insertions which are inserted into the notches in the side molds. Each positioning plate has a recess defined in an inner side thereof and the recess has patterns defined therein. The positioning plates snugly engaged with outside of the top mold. The present invention will become more obvious from the following 5 description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention. BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a cross sectional view to show the conventional shoe mold assembly; 10 Fig. 2 is an exploded view to show the mold assembly for making shoes of the present invention; 2 Fig. 3 is a cross sectional view to show the mold assembly of the present invention wherein the top mold is removed, and Fig. 4 is a cross sectional view to show the mold assembly of the present invention wherein the top mold is located on the top of the bottom mold and material of 5 the shoe is injected into the cavity. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to Figs. 2 to 4, the mold assembly for making shoes of the present invention comprises a bottom mold 10, two side molds 20, a top mold 40 and two positioning plates 30. The bottom mold 10 has a cavity 50 defined in a top thereof and 0 the cavity 50 is complementary to the shoe sole to be made. The two side molds 20 are movably connected to two sides of the bottom mold 10 and multiple notches 201 are defined in a top of an inside of each of the two side molds 20. Two positioning plates 30 are located on two respective top surfaces of the two side molds 20 and each of the two positioning plates 30 includes multiple insertions 5 302 which are inserted into the notches 201 in the side molds 20. Each positioning plate 30 has a recess 301 defined in an inner side thereof and the recess 301 has patterns defined in the inner surface thereof. When the top mold 40 is moved to the top of the bottom mold 10, the positioning plates 30 are snugly engaged with outside of the top mold 40 so as to seal the gap between the top mold 40 and the side molds 20. 10 Material such as rubber is injected into the cavity 50 to form the shoe sole and the positioning plates 30 prevent the material from leakage from the gap between the 3 top mold 40 and the side molds 20. Because the positioning plates 30 have patterns in the inner surface of the recesses 301 so that the shoe sole has patterns on the peripheral surface. The positioning plates 30 can be replaced with another set so as to have 5 different patterns. While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention. 4
