DETAILED DESCRIPTION

[0022] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0023] like Figure 1 As shown, the utility model provides a sandal outsole forming mold, comprising a first template 1, a second template 2 hinged to the top rear end of the first template 1, a convex mold 3 arranged on the bottom end surface of the second template 2, and a concave mold 4 matched with the convex mold 3 is provided on the top surface of the first template 1, and the raw material is extruded by the convex mold 3 and the concave mold 4 to form the sandal outsole;

[0024] When in use, the raw materials for the production of sandal outsoles are placed in the concave mold 4, and the second template 2 is pulled downward so that the second template 2 drives the convex mold 4 to be close to the top surface of the material, and then the first template 1 and the second template 2 with the material are pushed into the hot press. The material is subjected to high temperature and high pressure in the hot press and forms a sandal outsole under the cooperation of the convex mold 3 and the concave mold 4. After molding, the molding mold in the hot press is pulled out, and the second template 2 is pulled upward to take out the sandal outsole in the concave mold 4.

[0025] like Figure 2 and Figure 3 As shown, the present embodiment also includes a positioning assembly 5 disposed on the first template 1 and the second template 2, the positioning assembly 5 includes a plurality of positioning grooves 51 provided at the edge of the top surface of the first template 1 and offset from the concave mold 4, a plurality of positioning posts 52 installed on the bottom surface of the first template 1 and corresponding to the positioning grooves 51 one by one, the positioning posts 52 cooperate with the positioning grooves 51 to provide preliminary positioning for the second template 2, and a positioning sleeve 53 slidably installed in the positioning groove 51 and movably sleeved on the positioning post 52, the positioning sleeve 53 can slide vertically up and down along the inner side of the positioning groove 51, and the positioning sleeve 53 is sleeved on the positioning post 52 to provide further positioning for the second template 2;

[0026] The top of the positioning sleeve 53 is an open structure, and the positioning sleeve 53 is connected to the top end surface of the support plate 54 installed on the inner wall of the positioning groove 51 through the first spring 55, so that the positioning sleeve 53 is moved upward by the elastic force of the first spring 55 and is sleeved on the positioning column 52. A slide plate 56 movably connected to the inner side of the positioning groove 51 is arranged at the bottom of the support plate 54. A connecting column 57 and a transmission plate 58 are respectively installed on the top end surface and the side surface of the slide plate 56. The connecting column 57 is connected to the middle part of the bottom end surface of the positioning sleeve 53 at one end away from the slide plate 56. The slide plate 56 can move vertically up and down along the inner side of the positioning groove 51 to adjust the position of the positioning sleeve 53 through the connecting column 57.

[0027] The transmission plate 58 is movably connected to the inner wall of the positioning groove 51 at one end away from the slide plate 56. A push rod 59 is provided on the top of the transmission plate 58 to fit therewith. The push rod 59 is used to push the transmission plate 58 to move downward, so as to finally realize the downward movement of the positioning sleeve 53. The push rod 59 is movably extended into the inner side of the fixed cylinder 510 installed on the side surface of the second template 2, and the push rod 59 is connected to the inner top of the fixed cylinder 510 through the second spring 511. A limiting assembly 512 is provided on the inner side of the fixed cylinder 510 to provide positioning for the push rod 59.

[0028] In this embodiment, the inner wall of the positioning groove 51 is provided with a strip hole corresponding to the transmission plate 58, the strip hole passes through the side surface of the first template 1, and the distance between the inner bottom end surface of the strip hole and the bottom end surface of the transmission plate 58 is greater than the inner depth of the positioning sleeve 53, so that the transmission plate 58 can move vertically in the strip hole to adjust the position of the positioning sleeve 53;

[0029] A set of first springs 55 and a support plate 54 are respectively provided at the left and right ends of the bottom of the positioning sleeve 53, so that the positioning sleeve 53 can be stably moved vertically upward by the elastic force of the two first springs 55;

[0030] In this embodiment, the bottom of the push rod 59 is a hemispherical structure, and the push rod 59 and the fixing tube 510 are parallel to the side surface of the first template 1, so that the push rod 59 can stably push the transmission plate 58 when moving downward.

[0031] like Figure 4 As shown, in this embodiment, the limiting assembly 512 includes an elastic metal sheet 5121 installed on the side surface of the ejector rod 59, and the elastic metal sheet 5121 movably penetrates the inner side of the opening 5122 opened on the fixed cylinder 510, and the elastic metal sheet 5121 fits with the push block 5123 installed on the side surface of the first template 1 after passing through the inner side of the inclined opening 5122, so that the ejector rod 59 is positioned by the elastic metal sheet 5121 and the opening 5122;

[0032] In this embodiment, the inner diameter of the top of the fixed cylinder 510 is larger than the outer diameter of the ejector rod 59, so that the elastic metal sheet 5121 outside the ejector rod 59 can be easily contracted into the fixed cylinder 510;

[0033] The elastic metal sheet 5121 is tilted so that the push block 5123 squeezes the elastic metal sheet 5121 and shrinks it into the opening 5122 during the downward movement of the elastic metal sheet 5121;

[0034] In this embodiment, the sum of the elastic forces of the elastic metal sheet 5121 and the second spring 511 is smaller than the elastic force of the first spring 55, so that the push rod 59 is moved upward and reset by the elastic force of the first spring 55;

[0035] In this embodiment, the elastic metal sheet 5121 is made of stainless steel, which has strong corrosion resistance and longer service life;

[0036] When in use, the second template 2 drives the positioning column 52 and the fixing cylinder 510 to move downward when rotating downward, and the positioning column 52 moves downward into the positioning groove 51, and the positioning column 52 cooperates with the positioning groove 51 to provide preliminary positioning for the second template 2, while the fixing cylinder 510 drives the push rod 59 to move downward, and the push rod 59 moves downward to push the transmission plate 58 to move downward, and the transmission plate 58 drives the slide plate 56, the connecting column 57 and the positioning sleeve 53 to move downward, and the first spring 55 is compressed by the pressure of the positioning sleeve 53;

[0037] When the mold is subjected to pressure in the hot press, the second template 2 continues to move downward until it fits with the upper end surface of the first template 1. When the second template 2 fits with the first template 1, the elastic metal sheet 5121 contacts the push block 5123. The elastic metal sheet 5121 shrinks inward to the inside of the opening 5122 due to the pressure of the push block 5123. However, the elastic metal sheet 5121 and the opening 5122 no longer provide positioning for the ejector pin 59. Since the elastic force of the first spring 55 is greater than the sum of the elastic forces of the elastic metal sheet 5121 and the second spring 511, At this time, the positioning sleeve 53, the connecting column 57, the slide plate 56, the transmission plate 58 and the push rod 59 are moved upward by the elastic force of the first spring 55, the second spring 511 is compressed by the pressure of the push rod 59, and the elastic metal sheet 5121 slides in the fixed tube 510, and the positioning sleeve 53 moves upward and is sleeved on the positioning column 52. The positioning sleeve 53 cooperates with the positioning column 52 to further improve the positioning of the second template 2, prevent the first template 1 and the second template 2 from relative displacement, and improve the quality of the sandal outsole produced by the molding mold.
