Description

TECHNICAL FIELD

[0001] The utility model relates to shoemaking equipment field especially, relate to a secondary foaming forming machine with cold and hot pipeline. BACKGROUND

[0002] The traditional secondary foaming forming machine is pushed into the heating station of the secondary foaming forming machine to heat, then moves the mold into the cooling station to cool, and finally moves out of the cooling station. The above-mentioned movement of the mold needs to be operated manually, which consumes manpower and movement time, and the operator may be scalded during the operation process of moving the mold from the heating station to the cooling station. In addition, the mold is heated or cooled by heat conduction, and the heating or cooling efficiency is low. The Chinese patent with the patent announcement number CN104859105B discloses a cold and hot double-station rotary type rapid heat cycle injection mold and molding method, which heats and cools the mold cavity by contact heat transfer. Although the cold and hot double-station rotary type rapid heat cycle injection mold increases the heat conduction contact area between the heating plate and the core plate contact part, between the heating plate and the cavity plate contact part, between the cooling plate and the core plate contact part, and between the cooling plate and the cavity plate contact part, the mold heating and cooling need to be performed in different stations, and the production efficiency needs to be further improved. The Chinese patent with the patent announcement number CN104309047B discloses an automatic shoe material secondary foaming forming machine, which passes steam and cooling water into the mold through the input pipe and the return pipe in the heating and cooling mechanism. The input pipe and the return pipe are mixed with hot and cold, which easily causes damage to the input pipe and the return pipe, increasing the maintenance cost.

[0003] Therefore, it is necessary to design a secondary foaming forming machine which can improve the production efficiency without manual movement of the mold, avoid the problem of easy damage of the input pipe and the return pipe, and improve the heating or cooling efficiency.

Specifically, two forming spaces correspond to the left shoe material and the right shoe material respectively, and two forming spaces correspond to one first input channel 231 and one circulation channel 33, so that the left shoe material and the right shoe material are subjected to cold and hot forming at the same time, and the steam or the cooling liquid flows through the input channels 23 and the circulation channels 33 corresponding to the two forming spaces at a similar time, thereby ensuring that the two forming spaces of the same set of upper dies 31 and lower dies 32 are uniformly heated and the temperature is consistent, thereby ensuring stable product quality.

[0037] Each upper die 31 corresponds to one reflux channel 24 located in the upper die plate 21, and each lower die 32 corresponds to one reflux channel 24 located in the lower die plate 22; each reflux channel 24 is provided with two reflux transition ports 241 facing the upper die 31 or the lower die 32, and the reflux transition ports 241 extend to one side surface of the upper die plate 21 or the lower die plate 22; the reflux transition ports 241 of the upper die plate 21 are communicated with the other end of the circulation channel 33 of the upper die 31, and the reflux transition ports 241 of the lower die plate 22 are communicated with the other end of the circulation channel 33 of the lower die 32, so as to facilitate the steam, the cooling liquid or the air in the two forming spaces of the same die to flow to the hot reflux hose 113 or the cold reflux hose 124.

[0039] Specifically, referring to Figure 4The upper mold 31 and the lower mold 32 are a male and female mold, wherein the upper mold 31 is a male mold, the lower mold 32 is a female mold, and the female mold is on the lower side, which can effectively prevent the molding material from being squeezed and lost too much when being heated and melted. The circulation channel 33 of the upper mold 31 is arranged on the side of the protruding position of the male mold, and is arranged around so as to uniformly and quickly heat or cool the position of the upper mold 31 in the molding space. The circulation channel 33 of the lower mold 32 is arranged on the side of the recessed position of the female mold, and is arranged around so as to uniformly and quickly heat or cool the position of the lower mold 32 in the molding space. The input channel 23 of the upper mold plate 21 and the lower mold plate 22 can heat or cool the upper and lower sides of the molding space, respectively. Therefore, the heating flow channel, the cooling liquid flow channel or the air flow channel are arranged around each molding space, so as to improve the heating or cooling efficiency of the molding material in the molding space, ensure uniform heating or cooling, and improve the product quality.

[0040] The molding space is heated by introducing steam into the heating flow channel, cooled by introducing cooling liquid into the cooling liquid flow channel, and dried by introducing air into the air flow channel after cooling to remove the residual liquid in the air flow channel. The rapid heating and cooling of the molding space are realized, and the mold production efficiency is improved. Further, in the secondary foaming molding machine with the cold and hot pipelines, steam or cooling liquid is injected into the circulation channel 33 in the upper mold 31 and the lower mold 32, so that the mold is cold and hot formed in the same station without position shifting, and the production efficiency is improved.
