Technical Field

[0001] This utility model relates to the field of EVE foam shoe mold demolding technology, specifically to an EVE foam shoe mold demolding structure. Background Technology

[0002] EVE foam shoes are shoes made of EVA material, which has excellent toughness and resilience, and can provide good tensile strength and softness, as well as shock absorption and cushioning performance. After being processed by foaming technology, the shock absorption and cushioning performance of EVA material is further improved, which can effectively reduce foot fatigue during walking or exercise.

[0003] EVE foam shoes are typically manufactured using molds. However, when the finished EVE foam shoes are removed from the mold, they tend to stick to the upper or lower mold, making it difficult to demold them. Therefore, a new demolding structure for EVE foam shoes is proposed to solve this problem. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: an EVE foam shoe mold demolding structure, including a support, a lower heating plate fixed to the bottom wall of the inner side of the support, a lower mold fixed to the top of the lower heating plate, a cylinder fixed to the top of the support, an upper heating plate fixed to the output end of the cylinder, an upper mold fixed to the lower end of the upper heating plate, and an anti-adhesion structure provided at the front ends of the upper heating plate and the lower heating plate;

[0006] The anti-adhesion structure includes two air inlet chambers fixed to the front end of the lower mold. The front ends of the two air inlet chambers are fixed and connected to an air pump. The top end of each air inlet chamber is fixed and connected to a telescopic pipe. The other end of the telescopic pipe is fixed and connected to an upper pipe. The lower end of the upper pipe is fixed and connected to a T-shaped pipe. The rear end of each air inlet chamber is fixed and connected to two lower pipes. The top end of each lower pipe is fixed and connected to multiple air outlet pipes. The anti-adhesion structure also includes a filter structure disposed within the two air inlet chambers.

[0007] Furthermore, the top of the upper heating plate has two through holes for two upper tubes to pass through, and the upper tubes are fixed inside the through holes.

[0008] Furthermore, the top of the upper mold has two fixing holes for the interior of the two T-tubes, and the T-tubes are fixed inside the fixing holes.

[0009] Furthermore, the lower heating plate has two connecting holes at both ends of its front end for the lower tube to pass through, and the lower tube is fixed inside the connecting holes.

[0010] Furthermore, the lower mold has multiple connecting holes at both the left and right ends for the air outlet pipe to pass through, and the air outlet pipe is fixed inside the connecting holes.

[0011] Furthermore, the filtering structure includes filter plates disposed inside the two air intake chambers, with abutment plates fixed to the opposite walls of the two filter plates, and pull blocks fixed to the opposite walls of the two abutment plates. The filtering structure also includes two sets of first magnetic blocks fixed to the opposite walls of the two air intake chambers.

[0012] Furthermore, each of the two air intake chambers on opposite sides has an insertion hole for inserting a filter plate into it.

[0013] Furthermore, two sets of second magnetic blocks are fixed on the opposite side of each of the two abutments, with the first magnetic block corresponding to the second magnetic block.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0027] Furthermore, the top of the upper mold 6 is provided with two fixing holes for the two T-tubes 75 to be fixed inside. The T-tubes 75 are fixed inside the fixing holes, so that the T-tubes 75 can be fixed inside the upper mold 6.

[0031] Secondly, each of the two air intake chambers 71 has an insertion hole on its opposite side for inserting the filter plate 78 into it, so that the filter plate 78 can be inserted into the air intake chamber 71.

[0032] Meanwhile, two sets of second magnetic blocks are fixed on the opposite side of the two abutment plates 79, with the first magnetic block 711 corresponding to the second magnetic block, so that the abutment plates 79 can be fixed on the side wall of the air intake chamber 71, and the filter plate 78 can be stably located inside the air intake chamber 71.

[0033] It should be noted that all electronic components mentioned in this article are commonly known in the field of effective technology, and the control method of this embodiment is controlled by a controller. All electrical components mentioned in this article are connected to the controller and the power supply. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The provision of the power supply is also commonly known in the art. Therefore, this utility model will not explain the control method and circuit connection in detail.

[0034] The working principle of the above embodiments is as follows:

[0035] When using EVE foam shoes, the vacuum pump 72 operates to deliver outside air into the air inlet chamber 71 when the molded EVE foam shoes need to be removed from the upper mold 6 and lower mold 3. The air entering the air inlet chamber 71 enters multiple air outlet pipes 77 through two sets of lower pipes 76, allowing the multiple air outlet pipes 77 to deliver the air into the mold cavity of the lower mold 3. The impact force of the air gradually separates the bonded parts of the EVE foam shoes from the mold cavity of the lower mold 3. At the same time, the air in the air inlet chamber 71 enters the upper pipe 74 through the telescopic pipe 73, and the air in the upper pipe 74 enters the mold cavity of the upper mold 6 through the three-way pipe 75. The impact force of the air gradually separates the bonded parts of the EVE foam shoes from the mold cavity of the upper mold 6, thus effectively reducing the phenomenon of the EVE foam shoes sticking to the upper mold 6 and lower mold 3 when demolding, and effectively improving the convenience of demolding the EVE foam shoes.

[0036] Furthermore, when the air pump 72 delivers external gas into the air intake chamber 71, the external gas is filtered by the filter plate 78 to prevent dust in the external gas from adhering to the mold cavity of the upper mold 6 and the lower mold 3. By pulling the two left and right pull blocks 710 to move in opposite directions, the pull blocks 710 pull the filter plate 78 out of the air intake chamber 71 through the abutment plate 79, so that the two sets of first magnetic blocks 711 and second magnetic blocks on the opposite side are no longer attracted together, making it easier to replace the filter plate 78.

[0037] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0038] Although embodiments of the present invention 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 to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
