Description

Technical Field

[0001] The present invention relates to the technical field of injection molding, and particularly to a quantitative injection molding device for processing sole molds. Background Art

[0002] The injection molding device for sole molds is a key device for the automated production of soles. Its core function is to form materials such as rubber and plastic into soles through the injection molding process, and to ensure production efficiency, product quality and stability. The injection molding device for sole molds realizes the efficient operation of the entire process from material injection to demolding through the integration of an automated mechanical structure, a precision control system and a modular design. It is the core equipment for modern shoe-making industry to improve production capacity and ensure quality. When processing soles, the injection tube of the injection molding device needs to be placed in the injection port of the sole mold for discharging and injection molding. At present, when using the injection molding device to inject the sole mold, when the injection raw materials are materials with high fluidity such as PP, PE, and TPR, after the injection molding device stops injection molding, the raw materials in the injection tube have a low viscosity, and then the raw materials in the injection tube will flow out along the injection tube opening, resulting in an increase in the loss of raw materials. Summary of the Invention

[0003] In order to overcome the deficiencies of the prior art, the present invention provides a quantitative injection molding device for processing sole molds.

[0004] To solve the above technical problems, the present invention provides the following technical solutions: It includes an injection molding barrel, a fixed cylinder is fixedly connected to the injection molding barrel, a top plate is fixedly connected to the end of the fixed cylinder away from the injection molding barrel, a processing shell is fixedly connected to the top plate, an injection tube is provided on the processing shell, a starting component for processing raw materials is provided inside the fixed cylinder, a trigger column and a pressing column are provided inside the starting component, and the cooperation of the trigger column and the pressing column can provide power for processing raw materials. There are two sealing cylinders inside the starting component, each sealing cylinder is correspondingly fixedly connected to both sides of the fixed cylinder, a trigger column is inserted into each sealing cylinder, two limiting frames are fixedly connected to the outside of the fixed cylinder, each limiting frame is U-shaped, and the two limiting frames are correspondingly arranged on the tops of the two trigger columns. A limiting column is fixedly connected to each limiting frame, a rotating bar is movably connected to the outside of each limiting column, an active column is fixedly connected to both ends of each rotating bar, one end of each limiting column close to the trigger column is movably connected through the corresponding active column, and one end of each rotating bar away from the trigger column is movably connected through the corresponding active column to a translation block. The pressing column is arranged inside the fixed cylinder, a rotating disk is fixedly connected to the outside of the pressing column, two starting blocks are fixedly connected to the outside of the rotating disk, each starting block is triangular and inclined, and the two starting blocks are symmetrically distributed clockwise on the outside of the rotating disk, and the setting position of each starting block corresponds to the two trigger columns.

[0005] When quantitatively injecting plastic into the sole mold, the extrusion column rotates to drive the rotating disk to rotate. When the rotating disk rotates, it drives the starting block to rotate. When the starting block rotates to a position corresponding to the trigger column, the starting block fits with the trigger column. And when the starting block rotates, it pushes the fitted trigger column to move towards the position close to the sealing cylinder. When the trigger column moves, it pushes the rotating bar to rotate along the limit column through the corresponding movable column. When the rotating bar rotates, it drives the translation block to move towards the processing shell. The translation block provides power for cutting off the raw material inside the injection barrel.

[0006] As a preferred technical solution of the present invention, a truncation component for cooperating with the starting component is provided on the trigger column. A moving column and a truncation block are provided inside the truncation component. Through the cooperation of the moving column and the truncation block, the raw material injected from the injection barrel can be intercepted. Two blocking cylinders are provided inside the truncation component. The two blocking cylinders are correspondingly fixedly connected to both sides of the processing shell. A sealing ring is provided inside each blocking cylinder. A moving column is inserted into each blocking cylinder. The outer side of each moving column is fixedly connected to the corresponding sealing ring. One end of each moving column is fixedly connected to the corresponding translation block. Both truncation blocks are arranged inside the fixed cylinder. One end of each moving column away from the translation block is fixedly connected to a truncation block. A blocking plate is fixedly connected inside the fixed cylinder. A placement hole for the extrusion column to pass through is provided on the blocking plate. One end of each truncation block away from the moving column is set to be inclined, and the two truncation blocks are arranged in a staggered manner. A semi-circular arc groove is provided on the inclined part of each truncation block. And when the inclined parts of the two truncation blocks fit, the size of the semi-circular arc grooves on the two truncation blocks that fit corresponds to the diameter of the extrusion column.

[0007] When the translation block moves towards the processing shell, the translation block pushes the corresponding moving column to move towards the inside of the blocking cylinder. When the moving column moves, it drives the sealing ring to move. When the sealing ring moves, it drives the raw material inside the processing shell to converge towards the central position. Furthermore, when the moving column moves, it drives the two truncation blocks to move towards the central position of the blocking plate.

[0008] As a preferred technical solution of the present invention, a filling component for cooperating with the truncating component is provided at the bottom of the extrusion column. A fitting column and a rotating groove column are arranged inside the filling component. Through the cooperation of the fitting column and the rotating groove column, the raw materials accumulated in the fixed cylinder can be discharged. A support column is arranged inside the filling component. The support column is fixedly connected to the inside of the fixed cylinder. One end of the support column away from the fixed cylinder is fixedly connected with a positioning ring. A semi-cylinder is inserted into the positioning ring. A blocking strip is fixedly connected to the semi-circular arc part of the semi-cylinder. A slot for connecting the blocking strip is arranged on the positioning ring. The blocking strip is inserted into the slot of the positioning ring. A bearing disc is fixedly connected to the top of the semi-cylinder. A bearing is arranged on the bearing disc. The inner ring of the bearing of the bearing disc is fixedly connected to the extrusion column. The rotating groove column is fixedly connected to the outside of the extrusion column. A spiral groove for connecting the fitting column is arranged on the rotating groove column. The fitting column is inserted into the spiral groove of the rotating groove column. One end of the fitting column away from the rotating groove column is fixedly connected to the inner wall of the fixed cylinder. A machine shell is fixedly connected to the outside of the fixed cylinder. A stepping motor is arranged inside the machine shell. A transmission column is movably connected to the outside of the fixed cylinder. The output shaft of the stepping motor is fixedly connected to the transmission column. A gear is fixedly connected to one end of the transmission column away from the stepping motor. A plurality of tooth blocks are fixedly connected to one end of the semi-cylinder away from the blocking strip. And the gear meshes with the tooth blocks.

[0009] When it is necessary to inject the sole mold, the injection pipe is inserted into the injection port of the sole mold. Then, the injection raw materials inside the injection barrel enter the injection port of the sole mold through the injection pipe for injection. When it is necessary to block the injection raw materials in the injection barrel, the stepping motor is started. The stepping motor drives the transmission column to rotate. When the transmission column rotates, it drives the gear to rotate. When the gear rotates, it drives the engaged tooth blocks to move towards the position of the rotating disc. While the semi-cylinder moves, it drives the bearing disc to move. While the bearing disc moves, it drives the rotating groove column outside the extrusion column to move towards the position of the rotating disc. When the rotating groove column moves, due to the limitation of the fitting column, and because of the effect of the threaded groove provided on itself, the rotating groove column is blocked by the fitting column while moving. The rotating groove column rotates while moving. When the rotating groove column rotates, it drives the extrusion column to rotate. Due to the setting of the bearing disc at the bottom of the rotating groove column, the rotation of the rotating groove column will not drive the semi-cylinder to rotate. When the extrusion column rotates under the action of the rotating groove column and moves to the position corresponding to the blocking plate, the two truncating blocks move to the outside of the extrusion column. Then, the two truncating blocks are attached to the extrusion column.

[0010] As a preferred technical solution of the present invention, a reset component for cooperating with the starting component is provided on the outer side of the processing shell. There are two translation cylinders in the reset component. A support block is fixedly connected to the outer side of each translation cylinder. One end of each support block away from the translation cylinder is fixedly connected to the top of the processing shell. A bearing column is fixedly connected to the inside of each translation cylinder. A spring is sleeved on the outer side of each bearing column. Each translation cylinder is provided with a translation groove for the translation ring to move. A translation ring is inserted into each bearing column. The translation ring is composed of a circular ring and a long column. The two ends of each spring are respectively fixedly connected to the inner wall of the corresponding translation cylinder and the circular ring part of the translation ring. The long column part of the translation ring is fixedly connected to the corresponding translation block.

[0011] When the translation block drives the moving column to move, the translation block drives the translation ring to move along the bearing column while moving. When the translation ring moves, it drives the spring to compress. When the rotating disk drives the starting block to rotate to a position away from the trigger column, the starting block releases the blocking effect on the trigger column. Then, the compressed spring rebounds to drive the bearing column to rebound and reset. When the bearing column rebounds and resets, it drives the translation block to reset. When the translation block resets, it drives the rotating bar to reset and rotate. When the rotating bar resets and rotates, it drives the trigger column to reset. And when the translation block resets, it drives the moving column to reset. When the moving column resets, it drives the truncating block to move away from the center position of the blocking plate.

[0012] As a preferred technical solution of the present invention, an aggregate component for carrying the remaining material is provided on the outer side of the injection tube. An inlet shell is arranged in the aggregate component. The inlet shell is fixedly connected to the outer side of the injection tube. A loading box is inserted into the bottom of the inlet shell. A clamping strip is fixedly connected to the outer side of the loading box. A connecting column is fixedly connected to the outer side of the fixed cylinder. One end of the connecting column away from the fixed cylinder is fixedly connected to the inlet shell. A clamping groove for connecting the clamping strip is arranged on the connecting column. The clamping strip is clamped in the clamping groove of the connecting column.

[0013] When the injection molding is completed, the raw material overflowing from the injection port of the sole mold enters the inside of the inlet shell along the inclined piece. The remaining material entering the inside of the inlet shell flows into the inside of the loading box along the inner wall of the inlet shell. When the remaining material in the loading box is collected and needs to be replaced, the clamping state of the clamping strip and the connecting column is released, and then the loading box is taken off for replacement.

[0014] Compared with the prior art, the beneficial effects that the present invention can achieve are:

[0015] 1. Through the cooperation of the starting component, the truncating component and the filling component, when injecting the sole mold, through the cooperation of the trigger column, the truncating block and the extrusion column, the raw material in the injection tube can be blocked, avoiding the situation that the raw material in the injection tube flows out along the injection tube mouth due to low viscosity, reducing the loss of raw material and improving the utilization rate of raw material.

[0016] 2. Through the cooperation of the starting component, the truncating component and the filling component, when injecting plastic into the sole mold, the cooperation of the triggering column, the truncating block and the extrusion column can build the stability of the opening and closing of the raw material flow, achieve strict control of the flow accuracy, ensure homogeneous injection molding, and realize precise quantitative injection molding.

[0017] 3. Through the cooperation of the starting component, the truncating component and the filling component, when injecting plastic into the sole mold, the cooperation of the triggering column, the triggering column and the extrusion column can melt the bubbles generated inside the raw material when injecting the raw material, prevent the bubbles inside the raw material from entering the sole mold, and improve the stability of the injection into the sole mold.

[0018] 4. Through the cooperation of the filling component and the reset component, when injecting plastic into the sole mold, the cooperation of the translation block and the translation ring can realize the cycle of automatic injection to blocking to reset, and achieve efficient cycle of injection molding.

Through the cooperation of the starting component, the truncating component and the filling component, when injecting plastic into the sole mold, the cooperation of the rotating groove column and the fitting column can realize the automation of quantitative injection molding and raw material blocking, and improve the efficiency of injecting plastic into the sole mold.

[0020] 6. Through the setting of the aggregate component, when injecting plastic into the sole mold, the cooperation of the feeding shell and the loading box can collect the surplus material overflowed during the injection molding process, which is convenient for cleaning and maintenance and saves labor at the same time.

A processing shell 3 is fixedly connected to the top plate 5. An injection pipe 4 is provided on the processing shell 3.

The cooperation of the trigger post 8 and the pressing post 9 can provide power for processing raw materials. Two sealing cylinders 7 are provided inside the starting component. Each sealing cylinder 7 is correspondingly fixedly connected to both sides of the fixed cylinder 2. A trigger post 8 is inserted into each sealing cylinder 7. Two limiting frames 12 are fixedly connected to the outside of the fixed cylinder 2. Each limiting frame 12 is in a U shape, and the two limiting frames 12 are correspondingly arranged on the tops of the two trigger posts 8. A limiting post 14 is fixedly connected to each limiting frame 12. A rotating bar 13 is movably connected to the outside of each limiting post 14. An active post 15 is fixedly connected to both ends of each rotating bar 13. One end of each limiting post 14 close to the trigger post 8 is movably connected through the corresponding active post 15. One end of each rotating bar 13 away from the trigger post 8 is movably connected to a translation block 16 through the corresponding active post 15. The pressing post 9 is arranged inside the fixed cylinder 2. A rotating disk 10 is fixedly connected to the outside of the pressing post 9. Two starting blocks 11 are fixedly connected to the outside of the rotating disk 10. Each starting block 11 is in a triangular inclined shape, and the two starting blocks 11 are symmetrically distributed clockwise on the outside of the rotating disk 10, and the setting position of each starting block 11 corresponds to the two trigger posts 8;

[0036] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, when quantitatively injecting the sole mold, the pressing post 9 rotates to drive the rotating disk 10 to rotate. When the rotating disk 10 rotates, it drives the starting block 11 to rotate. When the starting block 11 rotates to the position corresponding to the trigger post 8, the starting block 11 fits with the trigger post 8, and when the starting block 11 rotates, it pushes the fitting trigger post 8 to move towards the position close to the sealing cylinder 7. When the trigger post 8 moves, it pushes the rotating bar 13 to rotate along the limiting post 14 through the corresponding active post 15. When the rotating bar 13 rotates, it drives the translation block 16 to move towards the direction of the processing shell 3. The translation block 16 provides power for cutting off the raw materials inside the injection barrel 1.

[0037] As Figure 4 , Figure 5 and Figure 6As shown, a truncation component for cooperating with a starting component is provided on the trigger post 8. A moving post 17 and a truncation block 20 are provided inside the truncation component. The raw material injected from the injection barrel 1 of the injection molding machine can be intercepted through the cooperation of the moving post 17 and the truncation block 20. Two blocking cylinders 18 are provided inside the truncation component. The two blocking cylinders 18 are fixedly connected to both sides of the processing shell 3 correspondingly. A sealing ring 19 is provided inside each blocking cylinder 18. A moving post 17 is inserted into each blocking cylinder 18. The outer side of each moving post 17 is fixedly connected to the corresponding sealing ring 19. One end of each moving post 17 is fixedly connected to the corresponding translation block 16. The two truncation blocks 20 are both arranged inside the fixed cylinder 2. One end of each moving post 17 far from the translation block 16 is fixedly connected to a truncation block 20. A blocking plate 21 is fixedly connected inside the fixed cylinder 2. A placement hole for the extrusion post 9 to pass through is provided on the blocking plate 21. One end of each of the two truncation blocks 20 far from the moving post 17 is inclined, and the two truncation blocks 20 are distributed in a staggered manner. A semi-circular arc groove is provided on the inclined part of each of the two truncation blocks 20. When the inclined parts of the two truncation blocks 20 are in contact, the size of the semi-circular arc grooves on the two truncation blocks 20 in contact corresponds to the diameter of the extrusion post 9;

[0038] As Figure 4 , Figure 5 and Figure 6 shown, when the translation block 16 moves towards the position of the processing shell 3, the translation block 16 pushes the corresponding moving post 17 to move towards the inside of the blocking cylinder 18. When the moving post 17 moves, it drives the sealing ring 19 to move. When the sealing ring 19 moves, it drives the raw material inside the processing shell 3 to converge towards the central position. Furthermore, when the moving post 17 moves, it drives the two truncation blocks 20 to move towards the central position of the blocking plate 21.

[0039] As Figure 7 , Figure 8 , Figure 9 and Figure 10As shown in the figure, a filling component for cooperating with the truncating component is provided at the bottom of the extrusion column 9. The filling component is provided with a fitting column 23 and a rotating groove column 24. Through the cooperation of the fitting column 23 and the rotating groove column 24, the raw materials accumulated in the fixed cylinder 2 can be discharged. A support column 25 is provided in the filling component. The support column 25 is fixedly connected to the inside of the fixed cylinder 2. One end of the support column 25 away from the fixed cylinder 2 is fixedly connected with a positioning ring 28. A semi-cylinder 27 is inserted into the positioning ring 28. A blocking strip 29 is fixedly connected to the semi-circular arc part of the semi-cylinder 27. A slot for connecting the blocking strip 29 is provided on the positioning ring 28. The blocking strip 29 is inserted into the slot of the positioning ring 28. A bearing disc 26 is fixedly connected to the top of the semi-cylinder 27. A bearing is provided on the bearing disc 26. The inner ring of the bearing of the bearing disc 26 is fixedly connected with the extrusion column 9. The rotating groove column 24 is fixedly connected to the outside of the extrusion column 9. A spiral groove for connecting the fitting column 23 is provided on the rotating groove column 24. The fitting column 23 is inserted into the spiral groove of the rotating groove column 24. One end of the fitting column 23 away from the rotating groove column 24 is fixedly connected to the inner wall of the fixed cylinder 2. A machine housing 6 is fixedly connected to the outside of the fixed cylinder 2. A stepping motor 31 is provided inside the machine housing 6. A transmission column 32 is movably connected to the outside of the fixed cylinder 2. The output shaft of the stepping motor 31 is fixedly connected with the transmission column 32. One end of the transmission column 32 away from the stepping motor 31 is fixedly connected with a gear 33. A plurality of tooth blocks 30 are fixedly connected to one end of the semi-cylinder 27 away from the blocking strip 29. And the gear 33 meshes with the tooth blocks 30;

[0040] As Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, when it is necessary to inject the sole mold, the injection pipe 4 is inserted into the injection port of the sole mold, and then the injection raw material inside the injection barrel 1 enters the injection port of the sole mold through the injection pipe 4 for injection. When it is necessary to block the injection raw material of the injection barrel 1, the stepping motor 31 is started. The stepping motor 31 drives the transmission column 32 to rotate. When the transmission column 32 rotates, it drives the gear 33 to rotate. When the gear 33 rotates, it drives the engaged tooth block 30 to move towards the position of the rotating disk 10. While the semi-cylindrical block 27 moves, it drives the bearing disk 26 to move. While the bearing disk 26 moves, it drives the rotating groove column 24 on the outside of the extrusion column 9 to move towards the position of the rotating disk 10. When the rotating groove column 24 moves, due to the limiting effect of the fitting column 23, while the rotating groove column 24 moves, due to the function of the threaded groove provided on itself, thus when the rotating groove column 24 moves, it is blocked by the fitting column 23. While the rotating groove column 24 moves, it rotates. While the rotating groove column 24 rotates, it drives the extrusion column 9 to rotate. Due to the setting of the bearing disk 26 at the bottom of the rotating groove column 24, the rotation of the rotating groove column 24 will not drive the semi-cylindrical block 27 to rotate. When the extrusion column 9 rotates, it drives the rotating disk 10 to rotate. When the extrusion column 9 moves to a position corresponding to the blocking plate 21 under the action of the rotating groove column 24, the two truncation blocks 20 move to the outside of the extrusion column 9, and then the two truncation blocks 20 are in contact with the extrusion column 9.

[0041] As Figure 11 shown, a reset assembly for cooperating with the start assembly is provided on the outside of the processing shell 3. There are two translation cylinders 34 in the reset assembly. A support block 35 is fixedly connected to the outside of each translation cylinder 34. One end of each support block 35 away from the translation cylinder 34 is fixedly connected to the top of the processing shell 3. A bearing column 36 is fixedly connected to the inside of each translation cylinder 34. A spring 37 is sleeved on the outside of each bearing column 36. Each translation cylinder 34 is provided with a translation groove for the movement of a translation ring 38. A translation ring 38 is inserted into each bearing column 36. The translation ring 38 is composed of a circular ring and a long column. The two ends of each spring 37 are fixedly connected to the inner wall of the corresponding translation cylinder 34 and the circular ring part of the translation ring 38 respectively. The long column part of the translation ring 38 is fixedly connected to the corresponding translation block 16.

[0042] As Figure 11As shown in the figure, when the translation block 16 drives the moving column 17 to move, the translation block 16 drives the translation ring 38 to move along the bearing column 36 while moving. When the translation ring 38 moves, it drives the spring 37 to compress. When the rotating disk 10 drives the starting block 11 to rotate to a position away from the trigger column 8, the starting block 11 releases the blocking effect on the trigger column 8. Then, the compressed spring 37 rebounds to drive the bearing column 36 to rebound and reset. When the bearing column 36 rebounds and resets, it drives the translation block 16 to reset. When the translation block 16 resets, it drives the rotating bar 13 to reset and rotate. When the rotating bar 13 resets and rotates, it drives the trigger column 8 to reset. At the same time, when the translation block 16 resets, it drives the moving column 17 to reset. When the moving column 17 resets, it drives the cutting block 20 to move away from the center position of the blocking plate 21.

[0043] As Figure 12 shown, an aggregate component for carrying the surplus material is provided on the outer side of the injection tube 4. An inlet shell 39 is arranged inside the aggregate component. The inlet shell 39 is fixedly connected to the outer side of the injection tube 4. A loading box 42 is inserted at the bottom of the inlet shell 39. A clamping strip 22 is fixedly connected to the outer side of the loading box 42. A connecting column 40 is fixedly connected to the outer side of the fixed cylinder 2. One end of the connecting column 40 away from the fixed cylinder 2 is fixedly connected to the inlet shell 39. A clamping groove for connecting the clamping strip 22 is arranged on the connecting column 40. The clamping strip 22 is clamped in the clamping groove of the connecting column 40;

[0044] As Figure 12 shown, when the injection molding is completed, the raw material overflowing from the injection port of the sole mold enters the inside of the inlet shell 39 along the inclined piece 41. The surplus material entering the inside of the inlet shell 39 flows into the inside of the loading box 42 along the inner wall of the inlet shell 39. When the surplus material inside the loading box 42 is collected and needs to be replaced, the clamping state of the clamping strip 22 and the connecting column 40 is released, and then the loading box 42 is removed for replacement.

[0045] Working principle:

[0046] The first step, as Figure 7 、 Figure 8 、 Figure 9 and Figure 10As shown, when injection molding is required for the sole mold, the injection tube 4 is inserted into the injection port of the sole mold, and then the injection raw material inside the injection barrel 1 enters the injection port of the sole mold through the injection tube 4 for injection molding. When it is necessary to block the injection raw material in the injection barrel 1, the stepping motor 31 is started. The stepping motor 31 drives the transmission column 32 to rotate. When the transmission column 32 rotates, it drives the gear 33 to rotate. When the gear 33 rotates, it drives the engaged tooth block 30 to move towards the position of the rotating disk 10. While the semi-cylindrical block 27 moves, it drives the bearing disk 26 to move. While the bearing disk 26 moves, it drives the rotating groove column 24 on the outer side of the extrusion column 9 to move towards the position of the rotating disk 10. When the rotating groove column 24 moves, due to the limiting effect of the fitting column 23, while the rotating groove column 24 moves, due to the effect of the threaded groove provided on itself, thus when the rotating groove column 24 moves, it is blocked by the fitting column 23. While the rotating groove column 24 moves, it rotates. While the rotating groove column 24 rotates, it drives the extrusion column 9 to rotate. Due to the setting of the bearing disk 26 at the bottom of the rotating groove column 24, the rotation of the rotating groove column 24 will not drive the semi-cylindrical block 27 to rotate. When the extrusion column 9 rotates, it drives the rotating disk 10 to rotate. When the extrusion column 9 moves to a position corresponding to the blocking plate 21 under the action of the rotating groove column 24, the two truncation blocks 20 move to the outer side of the extrusion column 9, and then the two truncation blocks 20 are in contact with the extrusion column 9;

[0047] Step two, as shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 When quantitative injection molding is performed on the sole mold, the extrusion column 9 rotates to drive the rotating disk 10 to rotate. When the rotating disk 10 rotates, it drives the starting block 11 to rotate. When the starting block 11 rotates to a position corresponding to the trigger column 8, the starting block 11 is in contact with the trigger column 8, and when the starting block 11 rotates, it pushes the contacted trigger column 8 to move towards the position close to the sealing cylinder 7. When the trigger column 8 moves, it pushes the corresponding movable column 15 to drive the rotating bar 13 to rotate along the limiting column 14 through the corresponding movable column 15. When the rotating bar 13 rotates, it drives the translation block 16 to move towards the processing shell 3. The translation block 16 provides power for blocking the raw material inside the injection barrel 1;

[0048] Step three, as shown in Figure 4 、 Figure 5 and Figure 6 When the translation block 16 moves towards the position of the processing shell 3, the translation block 16 pushes the corresponding moving column 17 to move inside the blocking cylinder 18. When the moving column 17 moves, it drives the sealing ring 19 to move. When the sealing ring 19 moves, it drives the raw material inside the processing shell 3 to converge towards the central position. Thus, while the moving column 17 moves, it drives the two truncation blocks 20 to move towards the central position of the blocking plate 21;

[0049] Step four, as shown inFigure 11 As shown, when the translation block 16 drives the moving column 17 to move, the translation block 16 drives the translation ring 38 to move along the bearing column 36 while moving. When the translation ring 38 moves, it drives the spring 37 to compress. When the rotating disk 10 drives the starting block 11 to rotate to a position away from the trigger column 8, the starting block 11 releases the blocking effect on the trigger column 8. Then, the compressed spring 37 rebounds to drive the bearing column 36 to rebound and reset. When the bearing column 36 rebounds and resets, it drives the translation block 16 to reset. When the translation block 16 resets, it drives the rotating bar 13 to reset and rotate. When the rotating bar 13 resets and rotates, it drives the trigger column 8 to reset. And when the translation block 16 resets, it drives the moving column 17 to reset. When the moving column 17 resets, it drives the truncating block 20 to move away from the center position of the blocking plate 21;

[0050] Step Five, as Figure 12 shown, when the injection molding is completed, the raw material overflowing from the injection port of the sole mold enters the inside of the feeding shell 39 along the inclined piece 41. The remaining material entering the inside of the feeding shell 39 flows along the inner wall of the feeding shell 39 into the inside of the loading box 42. When the remaining material inside the loading box 42 is collected and needs to be replaced, the clamping state between the clamping strip 22 and the connecting column 40 is released, and then the loading box 42 is removed for replacement.

Various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those skilled in the art to which the present invention pertains.
