Description

Technical Field

[0001] The invention relates to the technical field of sole molding and demoulding, and in particular to a sole rapid demoulding molding die for safety shoes. Background Art

[0002] Safety shoes are a special type of shoes designed to protect the wearer's feet and legs from dangers and injuries that may be encountered in the workplace. Safety shoes take functionality as the primary goal and are mostly made of rubber soles or PU soles to ensure safe use in specific environments. In the process of producing rubber soles, the rubber needs to be placed in a molding hot pressing mold, and the molding hot pressing mold is heated and sufficient pressure is applied to melt the rubber in the molding hot pressing mold to form the shape of the sole. After it is formed and cooled, the sole needs to be removed from the mold. In the process of removal, most of the time, the remaining edges are cut first with a manual handheld knife, and then the sole is taken out as a whole using a hook. During the process of hot pressing the sole, the sole is easily retained in the deep groove due to the pattern used to increase friction on the bottom. In this way, during the demolding process, the hot pressed sole is easily retained in the deep groove, and when the operator repeatedly takes it out, the operator is prone to stress concentration when taking out the sole, which causes the sole to be strained during demolding, affecting the integrity of the sole demolding.

[0015] 2. Through the sleeve connection setting of the stabilizing sleeve and the stabilizing column, stable support can be achieved on both ends of the support seat, ensuring that the multi-point demolding frame has additional stability in the installation groove, which can reduce local wear and damage of the multi-point demolding frame and the sole mold groove bracket, thereby extending the service life of the mold.

[0016] 3. By setting the moving components, the multi-point demolding frame can be pushed upward, so that the multi-point demolding frame slowly pushes the middle part of the bottom of the sole body upward, and the force can be applied more evenly, so that the sole body and the mold are slowly peeled off, which can effectively alleviate the contact area between the sole body and the mold, reduce local sticking or adhesion, help maintain the shape of the sole, and reduce the risk of deformation during the demolding process.

[0017] 4. By setting the limiting component, the two limiting blocks can be attached to and restricted on the outside of the sole body, so as to make the sole body contact between the two limiting blocks, which is convenient for stably supporting and lifting the sole body, and is conducive to the peeling of the multi-point demoulding frame from the sole body during resetting, so as to facilitate the demoulding operation of the sole body and further improve the demoulding efficiency of the sole body.

[0018] 5. The closing groove is moved downward by the downward movement of the upper mold, so that the connecting rod and the limiting block are moved and reset, and they are kept overlapped with the closing groove, so that the connecting rod and the limiting block are located in the closing groove, which can reduce the mutual interference between them, so that the upper mold and the sole mold groove are closed, which is convenient for the molding operation of the sole body.

[0019] 6. Through the elasticity of the spring itself, one side of the positioning frame can be pushed, so that the inclined surface of the connecting rod and the inclined surface of the connecting block are stably fitted, ensuring that the limiting block is stably pushed, so that the limiting block is fitted with the outside of the sole body. At the same time, the connecting rod can be automatically reset along the slide groove, which can reduce the user's operating steps, ensure the normal use of the connecting rod and the limiting block next time, and increase the convenience of the device.

[0037] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0038] The present invention provides Figure 1-Figure 7 The sole quick demoulding forming mold of a safety shoe shown in the figure comprises: a lower mold 1, an upper mold 11 and a first electric push rod 14, and a sole body 13 is arranged between the lower mold 1 and the upper mold 11, and a sole mold groove 12 for forming the sole body 13 is opened at the top of the lower mold 1;

[0039] The demoulding assembly 2 is used for stably demoulding the sole body 13 in the sole mold groove 12. The demoulding assembly 2 includes two multi-point demoulding frames 22 symmetrically installed in the sole mold groove 12 and two mounting grooves 21 provided in the sole mold groove 12 for the two multi-point demoulding frames 22 to slide, and the tops of the two multi-point demoulding frames 22 are in contact with the bottom of the sole body 13. A mounting seat 24 is installed at the bottom end of the lower mold 1. The bottom ends of the two multi-point demoulding frames 22 extend to the outside of the two mounting grooves 21 and are fixed with two supporting seats 25. Two lifting frames 23 are fixed at the bottom ends of the two supporting seats 25. Two groups of stabilizing components 4 supporting the two supporting seats 25 are provided on the mounting seat 24. A moving component 3 is provided on the mounting seat 24 for pushing the multi-point demoulding frames 22 to slide upward or downward along the mounting groove 21. Two groups of limiting components 5 are provided on the lower mold 1 for limiting the contact between the two sides of the moving sole body 13 and disconnecting the multi-point demoulding frames 22 from the sole body 13.

[0040] Each set of stabilizing components 4 includes a guide groove 43 opened at the top of the mounting seat 24 for the lifting frame 23 to be inserted, a stabilizing sleeve 41 fixed at the bottom end of the supporting seat 25, and a stabilizing column 42 fixed in the guide groove 43, and the stabilizing sleeve 41 is sleeved on the outside of the stabilizing column 42, and a resistance ring 44 is fixed at the top of the stabilizing column 42, and the resistance ring 44 is located in the stabilizing sleeve 41 and resists its internal top wall.

[0041] The moving assembly 3 includes a moving frame 31 installed on the top of the mounting seat 24, two moving wheels 33 installed on both sides of the moving frame 31, and two lifting grooves 34 opened on one side of the two lifting frames 23 for the two moving wheels 33 to slide. The moving frame 31 is located between the two lifting frames 23, and a guide rail 35 for the moving frame 31 to slide is fixed on the top of the mounting seat 24.

A second electric push rod 36 is fixed on the mounting seat 24, and the second electric push rod 36 is used to push the connecting plate 32 to move back and forth.

[0042] When the sole body 13 is demoulding, first the first electric push rod 14 pushes the upper mold 11 to move upward, so that the top of the sole body 13 loses contact with the sole mold groove 12, and the second electric push rod 36 drives the connecting plate 32 to move forward, and then the connecting plate 32 moves forward to push the moving frame 31 to move synchronously. At this time, the moving wheel 33 moves to the right in the lifting groove 34 along the moving edge of the moving frame 31 and pushes the lifting frame 23 to move upward, and the lifting frame 23 moves upward to slide it upward along the guide groove 43, and the lifting frame 23 moves to push the support seat 25 to move upward, and the support seat 25 moves upward to drive the stabilizing sleeve 41 to move upward along the stabilizing column 42, so that the conflict ring 44 loses contact with the stabilizing sleeve 41, which can ensure that the support seat 25 is stable and upward. The multi-point demoulding frame 22 moves, thereby the support seat 25 moves upward to push the multi-point demoulding frame 22 to slide upward along the installation groove 21. As the multi-point demoulding frame 22 moves, the sole body 13 is pushed to move upward along the sole mold groove 12. Subsequently, the sole body 13 and the mold are slowly peeled off, which can effectively alleviate the contact area between the sole body 13 and the mold and reduce local sticking or adhesion. Subsequently, the two multi-point demoulding frames 22 continue to move upward, which helps the sole body 13 to remain stable in the sole mold groove 12, can disperse the stress of the sole body 13 in the sole mold groove 12, can reduce the influence of stress concentration on the sole body 13, and improve the demoulding efficiency of the mold on the sole, so that the pushed out sole body 13 is taken out from the sole mold groove 12 to complete the demoulding operation of the sole body 13.

[0044] The reset assembly 6 includes a limiting groove 61 opened in the slide groove 58, a reset block 62 fixed on one side of the connecting rod 51, and a positioning rod 63 fixed in the limiting groove 61. The outer part of the positioning rod 63 is sleeved with a positioning frame 64, and one side of the positioning frame 64 extends to the outside of the limiting groove 61 and is fixed on one side of the reset block 62. A spring 65 is installed between the positioning frame 64 and the limiting groove 61.

[0045] Through the above technical solution:

[0046] When the sole body 13 moves upward along the sole mold groove 12, and the top of the sole mold groove 12 is exposed outside the lower mold 1, the upper mold 11 first moves upward continuously, driving the ear plate 52 to move upward, so that the closed groove 59 is slowly disengaged from the connecting rod 51 and the limiting block 57, and the guide rod 53 is driven to move upward by the upward movement of the ear plate 52. Then the guide rod 53 moves upward to pull the connecting block 54 to move upward along the guide frame 55 and disengage from the guide frame 55. At this time, the inclined surface on one side of the connecting block 54 contacts the inclined surface on one side of the connecting rod 51, so that the connecting rod 51 and the connecting block 54 are briefly connected.
