[0019] The utility model provides the following description with reference to the accompanying drawings to help fully understand the various embodiments of the utility model as defined by the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the utility model.

[0020] In the description of the present invention, descriptions of orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0021] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

[0022] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments: Figure 1-Figure 3 The hot pressing forming mold for rubber soles that can tear off burrs by hand shown in the figure includes an upper mold 1 and a lower mold 2. A punch 3 is arranged on the upper mold surface 11 of the upper mold 1, and a cavity 4 cooperating with the punch 3 is arranged on the lower mold surface 12 of the lower mold 2. It is characterized in that an upper mold overflow groove 5 is arranged on the upper mold surface 11 and is located on the edge of the punch 3 and is offset outward, and a lower mold overflow groove 6 is arranged on the lower mold surface 12 and is located on the edge of the cavity 4 and is offset outward. When the upper mold 1 and the lower mold 2 are closed, the upper mold overflow groove 5 and the lower mold overflow groove 6 are correspondingly connected.

[0023] In the utility model, an upper mold overflow groove 5 is offset on the outer side of the edge of the punch 3, and a lower mold overflow groove 6 is offset on the outer side of the edge of the cavity 4. When the upper mold 1 and the lower mold 2 are closed, the upper mold overflow groove 5 and the lower mold overflow groove 6 are correspondingly connected. Therefore, when the rubber material is formed in the punch 3 and the cavity 4, the excess material in the upper mold overflow groove 5 and the lower mold overflow groove 6 will also be formed accordingly. A circle of uniform connecting excess material will be formed between the rubber sole and the excess material in the upper mold overflow groove 5 and the lower mold overflow groove 6, and the thickness of the connecting excess material is also relatively thin. Therefore, after the rubber sole is taken out of the mold, the excess material on the outer periphery of the rubber sole can be manually torn off to complete the deburring operation without leaving any burrs, thereby ensuring the beauty of the sole and avoiding manual trimming, which not only greatly improves work efficiency but also reduces manual labor.

[0024] In the utility model, the distance between the edge of the punch 3 and the upper mold overflow groove 5 is 1mm-5mm, preferably 3mm, so that the distance between the rubber sole molding material and the excess material in the upper mold overflow groove 5 and the lower mold overflow groove 6 will not be too far, so that the connecting excess material between them connects the rubber sole with the excess material, making it easy to tear off the burrs.

[0025] Furthermore, the cross-sections of the upper die overflow groove 5 and the lower die overflow groove 6 are both semicircular arc structures, and the diameter of the semicircular arc is 1.5mm-2.5mm. Through the setting of the semicircular arc structure, the upper die overflow groove 5 and the lower die overflow groove 6 can be smooth and round, which is convenient for demolding and processing.

[0026] In the utility model, the male mold 3 and the female cavity 4 are both bilaterally symmetrical and there are two of them.

[0027] In the present invention, in order to facilitate accurate mold closing of the upper mold 1 and the lower mold 2, a plurality of positioning holes 51 are provided on the lower mold surface 12, and a plurality of positioning posts 52 cooperating with the positioning holes 51 are provided on the upper mold surface 11.

[0028] Furthermore, a first long groove 61 is provided at the upper side of the lower mold surface 12, and the length direction of the first long groove 61 extends in the left-right direction. A first retaining wall 62 cooperating with the first long groove 61 is provided at the upper side of the upper mold surface 11. Second long grooves 71 are spaced apart on the left and right sides at the lower side of the lower mold surface 12, and the length direction of the second long groove 71 extends in the left-right direction. Second retaining walls 72 cooperating with the second long groove 71 are spaced apart on the left and right sides at the upper side of the upper mold surface 11.

[0029] Limiting grooves 91 are provided on both the left and right sides of the lower mold surface 12 , and limiting flanges 92 cooperating with the limiting grooves 91 are provided on both the left and right sides of the upper mold surface 11 .

[0030] See also Figure 3 As shown, in order to facilitate the opening of the upper mold 1 and the lower mold 2, the upper side corners of the upper mold surface 11 and the lower mold surface 12 have a slope structure 70. Through the setting of the slope structure 70, the upper ends of the upper mold 1 and the lower mold 2 have a gap, so that the upper mold 1 and the lower mold 2 can be opened through the gap.

[0031] Furthermore, a notch 81 is provided at the lower side of the lower mold surface 12 and between the two second long grooves 71 .

[0032] In the utility model, the upper mold 1 and the lower mold 2 are both made of aluminum alloy, titanium steel or ceramic material.
