Description

Technical Field

[0001] This invention belongs to the field of shoemaking machinery technology, specifically a foot support component for quick shoe application in antistatic shoe processing. Background Technology

[0002] Antistatic shoes are a type of professional footwear designed to conduct static electricity from the human body to the ground. They are primarily manufactured using a one-piece molding process.

[0003] In the production of antistatic shoes, operators place the shoe upper onto the support frame and use a cylinder assembly to push the support frame downwards, precisely pressing it into the mold. The sole material quickly fills the gaps at the edges of the upper and undergoes molecular-level fusion with the upper material under high temperature and pressure. The support frame continuously applies stable pressure, ensuring a tight bond between the sole and upper, thus achieving integrated molding of the antistatic shoe. However, in actual production, if the support frame is designed too tightly, while it can stably support the upper during injection molding to ensure a stable fusion between the sole and upper, it makes it very difficult for operators to put the upper onto the support frame, potentially leading to hand fatigue and reduced production efficiency over long periods. Conversely, if the support frame is designed too loosely, while it makes putting on the upper easier, the upper is prone to slipping or slight displacement on the support frame during subsequent high-pressure injection molding, causing deviations in the interface between the upper and sole, affecting molding quality and the consistency of conductivity.

[0004] Therefore, based on the above problems, a foot support component for quick shoe application in antistatic shoe processing is proposed. Summary of the Invention

[0005] To address the problems mentioned in the background art, the present invention provides a foot support assembly for quick-fitting antistatic shoes, which solves the problems that if the foot support assembly is set too tightly, it will be difficult to fit into the shoe upper, and if it is set too loosely, it will slip and affect the subsequent molding quality of the shoe body.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a foot support assembly for quick shoe application in antistatic shoe processing, comprising a mounting plate and a foot support assembly, and further comprising: a hydraulic piston rod assembly installed in the foot support assembly; the mounting plate is provided with an arc-shaped groove; The foot support assembly includes a front part of the foot support and a connecting frame hinged to the mounting plate. A spring sleeve is fixedly connected to the bottom of the connecting frame. The rear part of the foot support is sleeved on the bottom of the spring sleeve, and the spring sleeve and the rear part of the foot support are connected through the spring part of the spring sleeve. A set of spring limiting crossbars are fixedly connected to the front part of the foot support in a symmetrical direction. The other end of the spring limiting crossbars is movably sleeved on the rear part of the foot support. In the initial state, the rear part of the foot support tends to move towards the rear part of the foot support due to the elastic force of the spring part on the spring limiting crossbars. The hydraulic piston rod assembly includes a telescopic piston rod one fixedly sleeved on the top of the spring sleeve. The bottom end of the telescopic piston rod one is fixedly connected to a connecting pipe, and the other end of the connecting pipe is fixedly connected to a telescopic piston rod two. The telescopic piston rod two is fixedly installed at the bottom rear of the foot support, and the output end of the telescopic piston rod two is fixedly connected to the front of the foot support. Initially, the top of the spring sleeve is in a contracted state, abutting against the arc surface at the bottom of the arc groove.

[0007] Preferably, the output end of the telescopic piston rod is provided with a ball bearing, and the top end of the telescopic piston rod can contact the arc-shaped groove through the ball bearing.

[0008] Preferably, a bottom support assembly is installed in the front part of the foot support to fill the gap between the rear part and the front part of the foot support after they are separated.

[0009] Preferably, the bottom support assembly includes a pressure rod fixedly installed in the spring sleeve and located below the telescopic piston rod. A set of support frames is symmetrically fixed inside the front part of the foot support. A vertical tension spring limiting rod is movably sleeved on one end of the support frame facing the rear part of the foot support. A T-shaped frame and a support base plate are fixedly connected to the top and bottom ends of the vertical tension spring limiting rod, respectively. One end of the support base plate is located directly below the pressure rod and is in contact with the pressure rod in the initial state. The gap between the front and rear parts of the foot support is equal to the width of the support base plate. In the initial state, the vertical tension spring limiting rod has an upward tendency due to the tension of its upper tension spring portion, and when the support base plate moves upward and follows the front part of the foot support toward the rear part of the foot support, it can be stored in the rear part of the foot support.

[0010] Preferably, the T-shaped frame has a straight slot, and a limiting device that can move horizontally within the straight slot is movably fitted inside the slot. A limiting rod is movably fitted vertically within the limiting device, and the bottom of the limiting rod is fixedly connected to the bottom of the rear cavity of the foot support.

[0011] Preferably, the support base plate is further equipped with a lateral support assembly for supporting the side of the gap between the rear and front parts of the foot support.

[0012] Preferably, the lateral support assembly includes a set of lateral support arc plates slidably mounted on the support base plate in a symmetrical direction, a guide plate is fixedly mounted on the top of the opposite end of the two lateral support arc plates, and a tension spring is fixedly connected to the opposite side of the two lateral support arc plates. An inclined block located above the two guide plates is fixedly mounted on the T-shaped frame. The bottom of the vertical tension spring limiting rod is two sets of columnar shapes, which can pass through the lateral support arc plate and be movably connected to it. The lateral support arc plate can slide horizontally between the bottom of the vertical tension spring limiting rod and the top of the support base plate. The top of the guide plate has opposite inclined surfaces, and the inclined surfaces of the top of the two guide plates are opposite each other. When the inclined block moves downward, it can push the two guide plates to move in opposite directions. After the two lateral support arc plates move towards each other, they can be retracted and stored in the rear of the foot support.

[0013] Preferably, the mounting plate has two sets of slots symmetrically arranged, and a spring collar is movably sleeved on the rear of the foot support. A set of locking pins is fixedly connected to the top of the spring collar symmetrically arranged. The top of the locking pins can extend into the connecting frame and movably connect with the connecting frame. The top of the locking pins can be engaged in the corresponding slots, and after the connecting frame is rotated outward by 90 degrees, the locking pins can be engaged in another corresponding slot. In the initial state, the spring collar has an upward tendency due to the action of its bottom spring.

[0014] Preferably, a spring plate is installed at the bottom rear of the foot support.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The above solution involves rotating the foot support assembly upwards, which in turn causes the spring sleeve to rotate the first telescopic piston rod. When the spring sleeve is in a horizontal position, the spring limit bar spring causes the front of the foot support to move towards the rear. Simultaneously, the output end of the first telescopic piston rod slides and extends along the surface of the arc groove. At this time, the hydraulic oil in the second telescopic piston rod flows back to the first telescopic piston rod through the connecting pipe, shortening the length of the second telescopic piston rod. When the front of the foot support is horizontal, the length of the mating part between the front and rear of the foot support decreases, making it easier for the operator to slip it onto the inclined plane. Then, rotating the foot support assembly downwards causes the top of the first telescopic piston rod to be squeezed by the arc groove, sending hydraulic oil into the second telescopic piston rod and pushing the front of the foot support to extend and provide a firm support for the upper. This solves the problems of the foot support assembly being too tight, making it difficult to slip onto the upper, and too loose, causing slippage and affecting the subsequent molding quality of the shoe. When the above solution supports the shoe upper by moving the front part of the foot support outward, the support frame will drive the support base plate to move outward until it is above the gap between the front and rear parts of the foot support. When the foot support assembly is pressed down as a whole and comes into contact with the mold, the spring sleeve will move downward relative to the rear part of the foot support and push the T-shaped frame downward. The T-shaped frame will drive the support base plate downward through the vertical tension spring limit rod and make the support base plate fill the gap between the front and rear parts of the foot support, thereby ensuring that a bulge occurs when this part is filled. The above solution, through the downward pressing of the T-shaped frame, also drives the inclined block downward to squeeze and press the two sets of guide plates respectively, so that the two sets of lateral support arc plates move in opposite directions and support the sides inside the shoe upper. This avoids the situation where bulges appear on the sides of the gap between the back and front of the foot support during subsequent filling, which would affect the shoe body forming efficiency.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1 to 8As shown, the present invention provides a foot support assembly for quick-release antistatic shoe processing, including a mounting plate 1 and a foot support assembly 2, and further including: a hydraulic piston rod assembly 3 installed in the foot support assembly 2; the mounting plate 1 has an arc-shaped groove 11; the foot support assembly 2 includes a foot support front part 23 and a connecting frame 25 hinged to the mounting plate 1, a spring sleeve 21 is fixedly connected to the bottom of the connecting frame 25, the bottom of the spring sleeve 21 is fitted with a foot support rear part 22, and the spring sleeve 21 and the foot support rear part 22 are connected through the spring part of the spring sleeve 21; a set of spring limiting crossbars 24 are fixedly fixed in a symmetrical direction on the foot support front part 23, the other end of the spring limiting crossbars 24 is movably fitted on the foot support rear part 22, and in the initial state, the foot support rear part 22 has a tendency to move towards the foot support rear part 22 due to the elastic force of the spring part on the spring limiting crossbars 24; The hydraulic piston rod assembly 3 includes a telescopic piston rod 31 fixedly sleeved on the top of the spring sleeve 21. The bottom end of the telescopic piston rod 31 is fixedly connected to a connecting pipe 32, and the other end of the connecting pipe 32 is fixedly connected to a telescopic piston rod 33. The telescopic piston rod 33 is fixedly installed at the bottom of the rear part 22 of the foot support, and the output end of the telescopic piston rod 33 is fixedly connected to the front part 23 of the foot support. Initially, the top end of the spring sleeve 21 is in a contracted state, abutting against the arc surface at the bottom of the arc groove 11. The output end of the telescopic piston rod 31 is provided with a ball, and the top end of the telescopic piston rod 31 can contact the arc groove 11 through the ball. A spring plate 221 is installed at the bottom of the rear part 22 of the foot support. Using the above scheme, by rotating the foot support assembly 2 upwards, the spring sleeve 21 drives the telescopic piston rod 31 to rotate. When the spring sleeve 21 is in a horizontal state, under the action of the spring portion of the spring limiting crossbar 24, the front part 23 of the foot support will move towards the rear part 22 of the foot support. At the same time, the output end of the telescopic piston rod 31 will slide and extend along the surface of the arc groove 11. At this time, the hydraulic oil in the telescopic piston rod 33 will flow back to the telescopic piston rod 31 through the connecting pipe 32, and the length of the telescopic piston rod 33 will become shorter. When the front part 23 of the foot support is in a horizontal state, the length of the mating part between the front part 23 of the foot support and the rear part 22 of the foot support will be reduced, making it easier for the operator to put it on the inclined plane. Then, the foot support assembly 2 is rotated downwards, and the top of the telescopic piston rod 1 31 will be squeezed by the arc groove 11 to send hydraulic oil into the telescopic piston rod 2 33 and push the front part 23 of the foot support to extend and provide a tight support for the shoe upper. This solves the problems that the foot support assembly is too tight, which makes it difficult to put it on the shoe upper, and too loose, which makes it easy to slip and affect the subsequent molding quality of the shoe body. It is worth noting that when the operator is putting on the shoe upper, the spring plate 221 can support the heel of the shoe upper in the retracted state of the front part 23 of the foot support, so that the shoe upper can be stably supported when the front part 23 of the foot support is pushed outward later.

[0020] like Figure 1 and Figures 4-7 As shown, a bottom support assembly 4 is installed in the front part 23 of the foot support to fill the gap between the rear part 22 and the front part 23 of the foot support after they are separated; the bottom support assembly 4 includes a pressure rod 45 fixedly installed in the spring sleeve 21 and located below the telescopic piston rod 31; a set of support frames 41 are fixedly connected in a symmetrical direction in the front part 23 of the foot support; a vertical tension spring limiting rod 43 is movably sleeved on one end of the support frame 41 facing the rear part 22 of the foot support; a T-shaped frame 42 and a support base plate 44 are fixedly connected to the top and bottom ends of the vertical tension spring limiting rod 43, respectively; one end of the support base plate 44 is located directly below the pressure rod 45 and is in contact with the pressure rod 45 in the initial state; The gap between the front part 23 and the rear part 22 of the foot support is equal to the width of the support base plate 44; in the initial state, the vertical tension spring limiting rod 43 has an upward tendency due to the tension of its upper tension spring part, and when the support base plate 44 moves upward and follows the front part 23 toward the rear part 22 of the foot support, it can be stored in the rear part 22 of the foot support; Using the above solution, when the support upper is moved outward by the front part 23 of the foot support, the support frame 41 will drive the support base plate 44 to move outward until it is above the gap between the front part 23 and the rear part 22 of the foot support. When the foot support assembly 2 is pressed down as a whole and comes into contact with the mold, the spring sleeve 21 will move downward relative to the rear part 22 of the foot support and push the T-shaped frame 42 downward. The T-shaped frame 42 will drive the support base plate 44 downward through the vertical tension spring limit rod 43 and make the support base plate 44 fill the gap between the front part 23 and the rear part 22 of the foot support, thereby ensuring that a bulge occurs in this part during filling.

[0021] like Figure 1 , Figure 4 , Figure 5 and Figure 7 As shown, a lateral support assembly 5 is also installed on the support base plate 44 to support the side of the gap between the rear part 22 and the front part 23 of the foot support; the lateral support assembly 5 includes a set of lateral support arc plates 51 that are symmetrically slidably installed on the support base plate 44, a guide plate 52 is fixedly installed on the top of the opposite end of the two lateral support arc plates 51, and a tension spring 53 is fixedly connected to the opposite side of the two lateral support arc plates 51; an inclined block 54 located above the two guide plates 52 is fixedly installed on the T-shaped frame 42. The bottom of the vertical tension spring limiting rod 43 is two sets of columnar shapes, which can pass through the lateral support arc plate 51 and be movably connected to it. The lateral support arc plate 51 can slide horizontally between the bottom of the vertical tension spring limiting rod 43 and the top of the support base plate 44. The top of the guide plate 52 is an inclined surface facing away from each other, and the inclined surfaces of the top of the two guide plates 52 are opposite each other. When the inclined block 54 moves downward, it can push the two guide plates 52 to move away from each other. After the two lateral support arc plates 51 move towards each other, they can be retracted and stored in the rear part 22 of the foot support. Using the above scheme, during the downward pressing of the T-shaped frame 42, the inclined block 54 will also be driven to press down and squeeze the two sets of guide plates 52 respectively, so that the two sets of lateral support arc plates 51 move in opposite directions and support the side inside the shoe upper. This avoids the situation where bulges appear on the side of the gap between the rear part 22 and the front part 23 of the foot support during subsequent filling, which would affect the shoe body forming efficiency.

[0022] like Figure 4 and Figure 6 As shown, a straight slot 421 is provided on the T-shaped frame 42. A limiting kit 422 that can move horizontally is movably fitted inside the straight slot 421. A limiting vertical rod 423 is movably fitted vertically in the limiting kit 422. The bottom of the limiting vertical rod 423 is fixedly connected to the bottom of the rear cavity of the foot support 22. By adopting the above solution, the T-shaped frame 42 is stabilized by the limiting vertical rod 423 when it moves downward, and the limiting kit 422 can also slide in the straight groove 421 when the foot support front 23 and the T-shaped frame 42 are moving.

[0023] The mounting plate 1 has two sets of symmetrical slots 12. The rear part 22 of the foot support is movably fitted with a spring collar 6. The top of the spring collar 6 is fixed with a set of locking pins 61 in a symmetrical direction. The top of the locking pins 61 can extend into the connecting frame 25 and be movably connected to the connecting frame 25. The top of the locking pins 61 can be locked into the corresponding slot 12. After the connecting frame 25 is rotated outward by ninety degrees, the locking pins 61 can be locked into another corresponding slot 12. In the initial state, the spring collar 6 has an upward tendency due to the action of the spring at its bottom. By adopting the above solution, during the rotation of the foot support assembly 2, the top of the locking pin 61 can be disengaged from the slot 12 by moving the spring collar 6 downwards. At this time, the lock on the rotation direction of the connecting frame 25 will be released. At the same time, when the foot support assembly 2 is rotated to a horizontal state, the spring force on the spring collar 6 can push the locking pin 61 into the corresponding slot 12 to lock the connecting frame 25 in the horizontal state, thus facilitating the operator to install the shoe upper later.

[0024] Working principle and usage process of this invention: In use, the operator rotates the foot support assembly 2 upwards, which in turn drives the telescopic piston rod 31 to rotate via the spring sleeve 21. When the spring sleeve 21 is in a horizontal state, the spring portion of the spring limit bar 24 will cause the front part 23 of the foot support to move towards the rear part 22 of the foot support. At the same time, the output end of the telescopic piston rod 31 will slide along the surface of the arc groove 11 and extend. At this time, the hydraulic oil in the telescopic piston rod 33 will flow back to the telescopic piston rod 31 through the connecting pipe 32. At this time, the length of the telescopic piston rod 33 will become shorter. When the front part 23 of the foot support is in a horizontal state, the length of the mating part between the front part 23 of the foot support and the rear part 22 of the foot support will be reduced, making it easier for the operator to fit the inclined surface. Then, the operator rotates the foot support assembly 2 downwards, and the top of the telescopic piston rod 31 will be squeezed by the arc groove 11 to send hydraulic oil into the telescopic piston rod 33 and push the front part 23 of the foot support to extend, thereby achieving a firming support effect on the shoe upper. During the rotation of the foot support assembly 2, the operator can first move the spring collar 6 downward to disengage the top of the locking pin 61 from the slot 12. At this time, the lock on the rotation direction of the connecting frame 25 will be released. At the same time, when the foot support assembly 2 is rotated to a horizontal position, the spring force on the spring collar 6 can push the locking pin 61 into the corresponding slot 12 to lock the horizontal connecting frame 25, thus facilitating the operator to install the shoe upper later. When the front part 23 of the foot support moves outward to support the shoe upper, the support frame 41 will drive the support base plate 44 to move outward until it is above the gap between the front part 23 of the foot support and the rear part 22 of the foot support. When the foot support assembly 2 is pressed down as a whole and comes into contact with the mold, the spring sleeve 21 will move downward relative to the rear part 22 of the foot support and push the T-shaped frame 42 downward. The T-shaped frame 42 will drive the support base plate 44 downward through the vertical tension spring limit rod 43 and make the support base plate 44 fill the gap between the front part 23 of the foot support and the rear part 22 of the foot support, thereby ensuring that there is a bulge when this part is filled. During the downward pressing of the T-shaped frame 42, it will also drive the inclined block 54 to descend and squeeze the two sets of guide plates 52 respectively, so that the two sets of lateral support arc plates 51 move in opposite directions and support the side inside the shoe upper. This avoids the situation where bulges appear on the side of the gap between the rear part 22 and the front part 23 of the foot support during subsequent filling, which would affect the shoe body forming efficiency.
