CZ2009218A3 - Mold assembly for manufacturing shoes - Google Patents

Abstract

The shoe making mold is formed by the lower mold part (10), the apex of which is provided with a concave pattern predetermined to form the sole, by the left and right mold side portions (20), each pressed against one side of the lower mold part (10) and spacer portions (30) which extend the upwardly left and right mold side portions (20), wherein the spacer portions (30) comprise concave recesses (301) and may be integrated with the side portions (20) or may be formed independently of the them.

Description

Technical field

The present invention relates to an assemblable shoe mold, more particularly to an assemblable mold, which includes spacers on the sides for effectively preventing material leakage from the mold.

BACKGROUND OF THE INVENTION

Known assembled molds for making shoes are typically formed by a lower mold part that includes a cavity at its apex, two mold side molds that can be pushed to the mold mold bottom, and an upper mold part that is positioned between the mold mold sides and encloses the cavity surrounded by the assembled mold . A material for casting a shoe sole, such as rubber, is injected into a cavity surrounded by a mold, and then the shoe sole is formed by solidifying the injected material. The basic difficulty associated with the requirement for careful placement of the mold side panels and the upper mold part is that the material readily penetrates the gaps between the mold side panels and the mold top, or the material cannot evenly fill the cavity. Both of these situations require additional working time to remove excess material, or even spoiled products must be discarded if the rubber is not evenly distributed. In addition, shoe soles made in known assembled forms cannot contain a pattern on the surface of their circumference and thus cannot attract the attention of the users.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an assembled shoe mold comprising two spacers provided on the upper surfaces of the mold side molds that seal the gap between the mold upper mold and the mold mold side molds so that no material leaks from the slot.

SUMMARY OF THE INVENTION

The above-mentioned disadvantages are solved by the assembled shoe mold of the present invention, which consists in that it consists of a lower mold part, two side mold parts, two spacer parts and an upper mold part. The lower mold part has a cavity at its apex. Both side mold parts are detachably attachable to the two sides of the bottom mold part. Notches are located in the upper portions of the mold side portions. The two spacer members are each located on its own upper face of one of the mold side members and each of the two mold members. The spacer parts comprise protrusions, in the assembled state, inserted into the notches formed in the side mold parts. Each of the spacer portions further comprises a recess on the inside of the recess in which the sample is located. The assembled shoe mold is further formed by an upper mold part removably positioned at the top of the lower mold part. In the assembled state, the spacer parts abut against the outer surface of the upper mold part. Alternatively, the spacers are replaceable to form another sample. The present invention will become more apparent from the following description when the accompanying drawings, which illustrate a uniform embodiment in accordance with the present invention, are for purposes of illustration only.

DETAILED DESCRIPTION OF THE INVENTION

The assembled shoe mold according to the exemplary embodiment shown in Figures 1 to 3 consists of a mold lower part 10, two mold side mold parts 20, a mold upper part 40 and two spacer parts 30. The mold lower part 10 comprises on its a cavity 50 that is complementary to the sole of the shoe to be manufactured. The mold side panels 20 are detachably attachable to the two sides of the mold bottom panel 10. The two spacer parts 30 form a superstructure of respective upper surfaces of the mold side panels 20. Each spacer 30 has a recess 301 on its inner side and the recess 301 includes a sample on its inner surface. When the upper mold part 40 is pushed to the top of the lower mold part 10, the spacer parts 30 abut against the surface of the upper mold part 40 in such a manner that it seals the gap between the upper mold part 40 and the side mold parts 20. When a material such as rubber is injected into the cavity 50 to form the shoe sole, the material spacing parts 30 prevent the gap between the upper parts 40 and the side parts 20, since the spacing parts 30 have a sample recess 301 on the inner surface. i made sole on its peripheral surface sample. Another assembled shoe mold shown in Figure 4 consists of a lower mold part 10, two mold side mold parts 20, an upper mold part 40, and two spacer parts 30. The lower mold part 10 comprises a cavity 50 at its top which is complementary to the sole of the shoe to be manufactured. The mold side panels 20 are detachably attachable to the two sides of the mold bottom panel 10, and notches 201 are located on the upper sides of the inner faces of the two mold side panels 20. The parts 30 comprise protrusions 302 which, when assembled, are inserted into the slots 201 formed in the mold side panels 20. Each spacer 30 has a recess 301 on its inner surface, and the recess 301 includes a sample on its inner surface. When the upper mold part 40 is pushed to the cavity located at the top of the lower mold part 10, the spacer parts 30 abut against the surface of the upper mold part 40 in such a manner that it seals the gap between the upper mold part 40 and the side mold parts 20. When material such as rubber is injected into the cavity 50 to form a shoe sole, the spacer 30 prevents material leakage from the gap between the upper panels 40 and the side panels 20. Because the spacer panels 30 include a pattern on the inner surface of the recess 301, the produced sole has a sample on its peripheral surface. In order to obtain a different sample, the spacer portions 30 may be replaced by the spacer portions 30 with a different sample.

Although we have shown and described embodiments that are in accordance with the present invention, it is clear that those skilled in the art can develop other solutions that will not be directed outside the scope of the present invention.
