[0002] A slipper is a type of shoe with an entirely open back and only a toe cap at the front. It is mostly flat-soled and often made of relatively light and soft leather, plastic, fabric, etc. Slippers are classified according to the wearing occasion and performance purpose. For example, beach slippers are not made of fabric but plastic, which is for waterproofing and easy cleaning. The toe cap type is also specially designed and is often called a thong slipper, that is, the so-called flip-flop. However, indoor slippers in winter may use flannel instead of plastic for warmth, enabling people to have a better experience indoors. There are also anti-slip slippers for bathing, as well as anti-static slippers commonly used in electronics factories and dust-free workshops, etc.

[0015] The sports slipper further includes a connecting part connected between the toe end and the heel end; the anti-slip bottom surface slopes upward gradually from the connecting part to the toe end; the anti-slip bottom surface slopes upward gradually from the connecting part to the heel end.

[0016] The shoe upper slopes upward gradually from the toe end to the heel end.

[0017] A manufacturing method of an integrally formed sports slipper includes the following steps:

[0018] S1. Mold closing: Set the upper mold, the middle mold, and the lower mold in the lifting channel. The first driving device drives the lower mold to rise and abut against the middle mold, so that the middle mold and the upper mold rise and abut against the top plate; the first inlet is communicated with the second inlet, and the raw material liquid enters the molding cavity through the first inlet and the second inlet.

[0036] An integrally formed sports slipper 1 comprises a sole 11 and an upper 12 integrally formed by injection molding with the sole 11. In actual implementation, the sole 11 and the upper 12 are integrally formed by injection molding, which can effectively improve manufacturing efficiency, save time, and reduce manufacturing costs.

[0037] Preferably, the sole 11 includes an anti-skid bottom surface 111; the anti-skid bottom surface 111 includes a plurality of first grooves 1111 extending along the length direction of the sole 11 and a plurality of second grooves 1112 extending along the width direction of the sole 11; the first grooves 1111 and the second grooves 1112 are staggered to separate the anti-skid bottom surface 111 to form an anti-skid boss 1113. In the actual implementation process, the anti-skid bottom surface 111 is in contact with the ground, and the first grooves 1111 and the second grooves 1112 have a drainage function, which can effectively cope with rainy days; at the same time, the anti-skid boss 1113 can prevent skidding, so as to prevent the sole 11 from slipping and the wearer from falling.

[0038] Preferably, the anti-skid bottom surface 111 has a plurality of anti-skid bosses 1113; the anti-skid bosses 1113 have a plurality of anti-skid grooves. Further, the anti-skid grooves increase the roughness of the anti-skid bottom surface 111, and the friction coefficient is increased to improve the friction force.

[0039] Preferably, the sole 11 further includes an anti-skid top surface 112 facing opposite to the anti-skid bottom surface 111; the anti-skid top surface 112 has anti-skid lines 1121 in the limiting groove. In actual implementation, the anti-skid top surface 112 contacts the foot, and the anti-skid lines 1121 are provided to prevent the foot from slipping, making it easier for people to wear.

[0040] Preferably, the sole 11 further comprises a shoe peripheral surface 113 connected between the top surface and the bottom surface; the shoe peripheral surface 113 has a decorative groove 1131. In the actual implementation process, the decorative groove 1131 improves the aesthetics of the sports slipper 1.

[0041] Preferably, the device groove includes a clearance groove section 1132 at the connection between the upper 12 and the sole 11. In actual implementation, the area where the upper 12 and the sole 11 are connected is easily cracked due to the mutual compression and extension between the sole 11 and the upper 12 after exercise. By providing the clearance groove section 1132 to provide a clearance space for the compression and extension, the damage of the connection of the sports slipper 1 is reduced, thereby improving the service life of the sports slipper 1.

[0042] Preferably, the sports slipper 1 further comprises a toe end portion corresponding to the toes and a heel end portion corresponding to the heel; the toe end portion has a first opening 13; the heel end portion has a second opening 14 connected to the first opening 13. In actual implementation, the first opening 13 is smaller than the second opening 14; the foot is inserted into the second opening 14, and the foot is limited by the first opening 13, so that the person can wear it easily.

[0043] Preferably, the sports slipper 1 further includes a connecting portion connected between the toe end portion and the heel end portion; the anti-slip bottom surface 111 gradually slopes upward from the connecting portion to the toe end portion; the anti-slip bottom surface 111 gradually slopes upward from the connecting portion to the heel end portion. In the actual implementation process, the heel end portion slopes upward, avoiding direct contact between the heel and the bottom surface to achieve a shock-absorbing effect, which can effectively reduce the fatigue of the wearer; the toe end portion slopes upward, which can effectively prevent people from bumping during walking and avoid falling and getting injured.

[0044] Preferably, the shoe upper 12 gradually slopes upward from the toe end portion to the heel end portion. In the actual implementation process, the shoe upper 12 fits the instep, which can effectively improve the comfort of the wearer.

[0045] A manufacturing method of an integrally formed sports slipper 1 includes the following steps:

[0046] S1. Mold closing: The upper mold 22, the middle mold 23, and the lower mold 21 are arranged in the lifting channel 31. The first driving device 33 drives the lower mold 21 to rise and abut against the middle mold 23, so that the middle mold 23 and the upper mold 22 rise and abut against the top plate 326; the first inlet 221 is communicated with the second inlet 3261, and the raw material liquid enters the molding cavity 24 through the first inlet 221 and the second inlet 3261;

[0047] S2. Solidifying and cooling: Wait for the raw material liquid to cool and solidify;

[0049] S4. Demolding: The second driving cylinder drives the upper mold 22 to move along the middle mold 23, driving the formed sports slipper 1 out of the middle mold 23 to complete demolding.

[0050] In the actual implementation process, the sports slipper 1 can be efficiently manufactured by this method, achieving the purpose of saving labor and cost.

[0051] A mold 2 for efficiently manufacturing a durable sole 11 includes a lower mold 21 at the bottom, an upper mold 22 at the top, and a middle mold 23 between the upper mold 22 and the lower mold 21; the upper mold 22, the lower mold 21, and the middle mold 23 are connected to form a molding cavity 24; the molding cavity 24 includes a bottom cavity 241 between the upper mold 22 and the middle mold 23 and a surface cavity 242 between the middle mold 23 and the lower mold 21. In the actual implementation process, the upper mold 22, the middle mold 23, and the lower mold 21 are connected to form the molding cavity 24. By injecting the raw material liquid into the injection cavity and demolding after the raw material liquid solidifies, a sports slipper 1 with an integrally formed shoe upper 12 and sole 11 can be obtained, which can effectively improve the manufacturing efficiency of the sports slipper 1 and thus reduce the production cost.

[0052] Preferably, the upper mold 22 has a first inlet 221 for the raw material liquid to enter; the first inlet 221 is communicated with the molding cavity 24. In the actual implementation process, the raw material liquid enters the molding cavity 24 through the first inlet 221 on the upper mold 22, efficiently filling the molding cavity 24; specifically, affected by gravity, the raw material liquid flows into the molding cavity 24 smoothly from top to bottom, quickly filling the molding cavity 24.

[0053] Preferably, the bottom cavity 241 includes a groove on the lower surface of the upper mold 22 and is formed after being connected to the upper surface of the middle mold 23; the upper mold 22 is slidably connected to the middle mold 23; the middle mold 23 has a chute extending along the length direction of the bottom cavity 241; the upper mold 22 has a sliding protrusion cooperating with the chute. In the actual implementation process, through the sliding connection, the upper mold 22 can be quickly combined with the middle mold 23 to efficiently form the bottom cavity 241; at the same time, during the demolding process, the upper mold 22 can move along the length direction of the shoe, taking out the sports slipper 1 on the middle mold 23, enabling the injection-molded sports slipper 1 to be quickly demolded, thereby improving the production efficiency of the sports slipper 1.

[0054] Preferably, the lower mold 21 includes two connecting convex columns 211 respectively located on both sides of the surface cavity 242; the connecting convex columns 211 are on the upper surface of the lower mold 21; the middle mold 23 has connecting holes 212 on the lower surface of the middle mold 23 and cooperating with the connecting convex columns 211. In the actual implementation process, through the cooperation of the connecting convex columns 211 and the connecting holes 212, the lower mold 21 can be quickly connected to the middle mold 23 to form the surface cavity 242, effectively improving the production efficiency.

[0055] Preferably, the middle mold 23 includes a first mold body 231 on the outside and a second mold body 232 on the inside; the first mold body 231 has a receiving cavity 2311 for receiving the second mold body 232; the second mold body 232 has a plurality of protruding portions 2321 that can actively protrude from the first mold body 231 and enter the bottom cavity 241; the first mold body 231 has a protruding hole cooperating with the protruding portions 2321. In the actual implementation process, the second mold is in the receiving cavity 2311, the protruding hole is on the upper surface of the first mold body 231, and the second mold body 232 rises so that the protruding sections of the second mold body 232 protrude from the protruding holes and enter the bottom cavity 241; during injection molding, anti-slip lines 1121 will be formed at the positions of the protruding sections on the sports slipper 1, making the person wearing the sports slipper 1 more comfortable; at the same time, during demolding, the second mold body 232 descends, and the protruding sections contract into the protruding holes, enabling the upper mold 22 to drive the sports slipper 1 to move smoothly and efficiently along the length direction of the shoe, effectively improving the demolding efficiency, and thus improving the production efficiency.

[0056] Preferably, the second die body 232 further includes a stop segment 2322 connected to the protruding portion 2321 and located within the accommodation cavity 2311; the connecting stud 211 has an extending segment extending into the accommodation cavity 2311. During actual implementation, after the lower die 21 ascends, the connecting stud 211 extends into the accommodation cavity 2311 from the connecting hole 212 to abut against the stop segment 2322, thereby causing the extending segment to protrude; during demolding, after the lower die 21 descends, the connecting stud 211 disengages from the accommodation cavity 2311, and the stop segment 2322 causes the extending segment to move out of the bottom cavity 241 under the action of gravity; during mold closing, the lower die 21 can be efficiently connected to the middle die 23, and at the same time, the extending segment protrudes; during demolding, the lower die 21 can be efficiently separated from the middle die 23, and at the same time, the extending segment contracts; the production efficiency can be effectively improved.

[0057] Preferably, the upper die 22 includes a first half die 222 and a second half die 223 hinged to the first half die 222; the upper die further includes a hinge shaft 224 provided at the heel end and a compression spring 225 provided at the toe end. During actual implementation, since the sports slipper 1 has a decorative groove 1131 on the shoe peripheral surface 113 of the sole 11, corresponding protrusions are provided on the side plates of the groove of the upper die 22 so that the sports slipper 1 can be integrally injection molded; when the upper die 22 drives the sports slipper 1 to disengage from the middle die 23, the sports slipper 1 falls out of the groove of the upper die 22 under the action of gravity. At this time, the decorative groove 1131 and the corresponding protrusions will prevent the sports slipper 1 from falling naturally; therefore, a hinge shaft 224 is provided at the heel end of the mold 2 and a compression spring 225 is provided at the toe end, so that the first half die 222 and the second half die 223 of the upper die 22 are separated, thereby causing the corresponding protrusions to disengage from the decorative groove 1131 and preventing the decorative groove 1131 and the corresponding protrusions from hindering the falling of the sports slipper 1, and the production efficiency of the sports slipper 1 can be effectively improved.

[0058] A device for efficiently manufacturing a durable sole 11 includes a device main body; the device main body includes a mold 2 and an auxiliary mechanism 3 for assisting the mold 2 to open and close; the auxiliary mechanism 3 includes a lifting channel 31 for accommodating the mold 2 and vertically arranged, a housing 32 outside the lifting channel 31, and a first driving device 33 in the lifting channel 31 for driving the mold 2 to move along the lifting channel 31. In the actual implementation process, the auxiliary mechanism 3 assists the mold 2 to open and close efficiently, improving the production efficiency; specifically, the upper mold 22, the middle mold 23, and the lower mold 21 are arranged from top to bottom and placed in the lifting channel 31. The first driving device 33 in the lifting channel 31 includes a first driving cylinder; when closing the mold, the first driving cylinder extends to abut against the lower mold 21, and the lower mold 21 rises to fit with the middle mold 23, driving the upper mold 22 upward and then the mold 2 abuts against the housing 32, and the molds 2 are pressed together; at this time, the raw material liquid is injected into the molding cavity 24. After the sports slipper 1 is formed, the mold is opened; when opening the mold, the first driving cylinder contracts, the lower mold 21 descends, the middle mold 23 is separated from the lower mold 21, and the sports slipper 1 remains on the middle mold 23; through the auxiliary mechanism 3, the molds 2 are efficiently joined and separated; it can effectively improve the efficiency of mold opening and closing, and further improve the manufacturing efficiency of the sports slipper 1.

[0059] Preferably, the housing 32 includes a top plate 326 above the lifting channel 31, a bottom plate below the lifting channel 31, and connecting side plates 321 connecting the top plate 326 and the bottom plate; the middle mold 23 is slidably connected to the connecting side plates 321; the connecting side plates 321 include a limiting step 322 for limiting the middle mold 23. In the actual implementation, the middle mold 23 is supported by the limiting step 322, facilitating the joining and separation of the molds 2; specifically, the limiting step 322 can limit the middle mold 23 and cannot limit the lower mold 21; during the mold closing process, the lower mold 21 below the limiting step 322 can abut against the middle mold 23 through the limiting step 322 to drive the middle mold 23 to rise; during the mold opening process, the lower mold 21 above the limiting step 322 descends and enters the area below the limiting step 322 through the limiting step 322. Due to the limiting effect of the limiting step 322 on the middle mold 23, the middle mold 23 is limited, hindering the middle mold 23 from descending, and thus the lower mold 21 is separated from the middle mold 23, enabling efficient mold opening and closing and improving the production efficiency of the sports slipper 1.

[0060] Preferably, the connecting side plates 321 are connected and composed of a first side plate, a second side plate, and a third side plate connecting the first side plate and the second side plate; the limiting step 322 includes a first step stage on the first side plate, a second step stage on the second side plate, and a third step stage on the third side plate.

In actual implementation, the second driving device 325 comprises a second driving cylinder, which drives the upper mold 22 to move efficiently along the length direction of the bottom cavity 241, thereby allowing the sports slippers 1 to be quickly detached; meanwhile, during the manufacturing process, the second driving cylinder will follow the upper mold 22 in the lifting and lowering movement, and the second driving cylinder will be released through the clearance channel 3243, so that the second driving cylinder can be lifted and lowered efficiently.
