Description

Technical Field

[0001] The present invention relates to the technical field of injection molding devices, and particularly to a sole injection production device. Background Art

[0002] During the sole injection molding process, the presence of moisture in the material is inevitable: on the one hand, high molecular materials such as TPU and nylon are hygroscopic and easily adsorb moisture from a humid environment; on the other hand, if the raw materials are not well sealed during storage and transportation, or if the drying process parameters (temperature, time) are set improperly, moisture will remain. The moisture in the material vaporizes into gas during high-temperature melting. If it cannot be discharged in time, it is easy to form bubbles inside the sole, affecting the product strength and appearance.

[0003] For the problem of mold exhaust in the prior art, the exhaust effect is mainly improved through fixed structure design (such as opening exhaust grooves, using the parting surface or ejector pin clearance) combined with auxiliary vibration technology. For example, exhaust grooves with fixed dimensions are set at the edge of the mold cavity, or the mold is driven to generate periodic shaking by a vibration motor to promote the migration of gas in the melt to the exhaust structure. However, such solutions have significant defects: the vibration intensity is usually preset as a fixed value based on experience and is not dynamically related to the moisture content of the material. When the moisture content of the material fluctuates due to factors such as raw material batches and environmental humidity, the fixed vibration parameters cannot adapt to the real-time exhaust requirements: if the moisture content is high, the fixed vibration intensity may not be sufficient to push the gas out quickly, resulting in bubble residues; if the moisture content is low, excessive vibration may damage the melt flow stability, causing new defects such as weld lines and rough surfaces. Summary of the Invention

[0004] The present invention solves the problem that the fixed vibration intensity in the prior art cannot meet the exhaust requirements of different materials by providing a sole injection production device.

[0005] To achieve the above object, the present invention is realized through the following technical solutions:

[0006] The present invention provides a sole injection production device, including a movable mold and a fixed mold that can be opened and closed. The movable mold and the fixed mold respectively have exhaust holes and injection holes. The injection molding device further includes:

[0007] An injection assembly for injecting material into the movable mold and the fixed mold after clamping, and the injection assembly seals the injection hole during the injection of the material;

[0008] A moisture monitoring assembly communicated with the exhaust hole. The moisture monitoring assembly includes a cylinder body, and the cylinder body has an air outlet. The moisture content of the material is monitored by the gas volume difference between the gas entering the cylinder body per unit time and the gas flowing out through the air outlet;

[0009] A vibration exhaust assembly disposed on one side of the fixed mold. The vibration exhaust assembly includes a percussion ball that linearly drives along the height of the fixed mold and reciprocally strikes the fixed mold. The moving speed of the fixed mold is negatively correlated with the gas volume difference, and the percussion frequency is positively correlated with the gas volume difference.

[0010] Further, the injection assembly includes a linear driving member and an injection tube disposed at the driving end of the linear driving member. A fixed ring and a sliding ring are sleeved on the injection tube up and down. The fixed ring is fixed to the injection tube, and the sliding ring is slidably connected to the injection tube. A corrugated pipe is fixed between the fixed ring and the sliding ring. An electromagnetic member one and a heat insulation gasket are respectively fixed to the upper and lower ends of the sliding ring.

[0011] Further, the moisture monitoring assembly includes an air outlet pipe communicated with the air outlet pipe. The air outlet pipe is communicated with a cylinder body. A cylinder plate is hermetically slidably connected in the cylinder body. An air outlet hole is opened in the cylinder plate. An elastic member one is connected between the air outlet hole and the cylinder body. A resistance block is fixed to the outer peripheral surface of the cylinder plate, and a resistance plate is embedded in the inner wall of the cylinder body. The resistance plate is in contact with the resistance block. The resistance plate, the resistance block and the linear driving member are connected in series.

[0012] Further, the vibration exhaust assembly includes a bracket fixed on one side of the fixed mold. A lead screw and a rotating rod are rotatably connected in parallel to the inner walls on both sides of the bracket. A driving structure is connected to the lead screw and the rotating rod. A moving plate is sleeved on the lead screw. The moving plate is attached to the fixed mold. A lever is hinged to the moving plate. The percussion ball is fixed to one end of the lever. A pull rod is hinged to the other end of the lever. A limit pin is fixed to the end of the pull rod away from the other end of the lever. A turntable is in spline fit with the rotating rod. A limit groove in a wavy shape is opened on the turntable.

[0013] Further, the driving structure includes a gear pair arranged on the lead screw and the rotating rod, an electromagnetic clutch arranged on the periphery of the lead screw and below the gear pair, and a driving member for driving the lead screw. The electromagnetic clutch is connected in series with the resistance plate and the resistance block.

[0014] Further, the injection molding device further includes a demolding assembly. The demolding assembly includes a groove. The groove includes a sliding groove opened on the inner side of the moving mold, an air inlet groove communicated with the sliding groove, and an air outlet groove communicated with the air inlet groove and the sliding groove. The other end of the air inlet groove is communicated with an electromagnetic member two. A plug block is hermetically slidably connected in the sliding groove. A connecting rod is fixed to the side of the plug block away from the cavity. A sliding plate with ferromagnetism is fixed to the end of the connecting rod away from the plug block. An elastic member two is fixed between the sliding plate and the sliding groove. An electromagnetic member two is fixed to the inner wall of the sliding groove.

The gas volume difference between the gas entering the cylinder and flowing out through the air holes per unit time is converted into the displacement of the resistance block relative to the resistance plate, so as to correspondingly adjust the injection speed of the injection component, the rising speed of the injection pipe, the engagement strength of the gear pair, further adjust the rotation speed of the lead screw, that is, the rising speed of the knocking ball, and the rotation speed and torque of the rotating rod, that is, the vibration frequency and strength transmitted to the knocking ball by the lever, so that the present invention can change the injection speed and vibration intensity according to the moisture content of different materials, ensuring that the gas is completely exhausted to avoid affecting the product quality.

Detailed implementation manners

[0028] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] Embodiment 1:

[0031] Refer to Figures 1 to 7, A sole injection production device, including a movable mold 1 and a fixed mold 2 that can be opened and closed. The movable mold 1 and the fixed mold 2 respectively have exhaust holes 11 and injection holes 21. The movable mold 1, the fixed mold 2, the exhaust holes 11, and the injection holes 21 are common structures in the prior art. Other structures related to the movable mold 1 and the fixed mold 2 that meet the normal injection requirements are not drawn; an injection assembly 3 for injecting materials into the combined movable mold 1 and fixed mold 2. Only the injection pipe 31 is simply drawn in the figure, and the injection assembly 3 seals the injection hole 21 during the injection of materials, that is, to ensure that there is no other air outlet channel except the exhaust hole 11 during the injection molding process; a moisture monitoring assembly 4 connected to the exhaust hole 11. The moisture monitoring assembly 4 includes a cylinder body 42. The cylinder body 42 has an air outlet hole 45, and monitors the moisture content of the material by the gas volume difference between the gas entering the cylinder body 42 and the gas flowing out through the air outlet hole 45 per unit time, and obtains the moisture content of the material by the gas volume difference; a vibration exhaust assembly 5 arranged on one side of the fixed mold 2. The vibration exhaust assembly 5 includes a knocking ball 56 that linearly drives along the height of the fixed mold 2 and reciprocally knocks the fixed mold 2. The moving speed of the fixed mold 2 is negatively correlated with the gas volume difference, and the knocking frequency is positively correlated with the gas volume difference. The moving speed and the knocking frequency have an inverse relationship.

[0032] To ensure the sealing performance of the injection hole 21, the injection assembly 3 includes a linear driving member 32 and an injection pipe 31 arranged at the driving end of the linear driving member 32. The linear driving member 32 is prior art and includes a lead screw. The injection pipe 31 is sleeved with a fixed ring 33 and a sliding ring 35 up and down. The fixed ring 33 is fixed to the injection pipe 31, and the sliding ring 35 is slidably connected to the injection pipe 31. A corrugated pipe 34 is fixed between the fixed ring 33 and the sliding ring 35. Electromagnetic member 1 37 and a heat-insulating sealing gasket 36 are respectively fixed to the upper and lower ends of the sliding ring 35. The electromagnetic member 1 37 is an electromagnetic device in the prior art. Before injecting materials, the injection pipe 31 first enters the cavity through the injection hole 21. The heat-insulating sealing gasket 36 first contacts the upper end of the fixed mold 2, and the electromagnetic member 1 37 is energized to generate a magnetic attraction force with the fixed mold 2 (both the movable mold 1 and the fixed mold 2 have ferromagnetism) to maintain the sealing performance between the sliding ring 35 and the fixed mold 2 and prevent gas leakage.

[0033] Refer to Figure 7 , The moisture monitoring assembly 4 includes an air outlet pipe 41 connected to the air outlet pipe 41. The air outlet pipe 41 is connected to a cylinder body 42. A cylinder plate 43 is hermetically and slidably connected inside the cylinder body 42. An air outlet hole 45 is opened in the cylinder plate 43. An elastic member 1 44 is connected between the air outlet hole 45 and the cylinder body 42. A resistance block 47 is fixed to the outer peripheral surface of the cylinder plate 43. A resistance plate 46 is embedded in the inner wall of the cylinder body 42, and the resistance plate 46 is in contact with the resistance block 47. The right end of the resistance plate 46 is an electrical connection end. The resistance plate 46, the resistance block 47, and the linear driving member 32 are connected in series. Under normal circumstances, the resistance block 47 is located at the right end of the resistance plate 46, and at this time, the resistance values of the resistance plate 46 and the resistance block 47 in the circuit are relatively large.

[0034] Referring to Figures 2 to 5 , the vibration exhaust assembly 5 includes a bracket 51 fixed to one side of the fixed mold 2. The inner walls on both sides of the bracket 51 are rotatably connected in parallel with a lead screw 52 and a rotating rod 53. The lead screw 52 and the rotating rod 53 are connected with a driving structure 59 to transmit torque through the driving structure 59. A moving plate 54 is sleeved on the lead screw 52. The moving plate 54 is attached to the fixed mold 2. Under the limitation of the fixed mold 2, the moving plate 54 vertically rises under the drive of the lead screw 52. A lever 55 is hinged on the moving plate 54. The moving plate 54 and the lever 55 form a lever structure. A knocking ball 56 is fixed at one end of the lever 55. A pull rod 58 is hinged at the other end of the lever 55. A limit pin is fixed at the other end of the pull rod 58 away from the lever 55. A turntable 57 is in spline fit with the rotating rod 53. A limiting groove in a wavy shape when unfolded is formed on the turntable 57. In the rotating state, the turntable 57 drives one end of the lever 55 to fluctuate through the cooperation of the limiting groove and the limit pin, and the knocking ball 56 at the other end knocks on the fixed mold 2.

[0035] Specifically, referring to Figure 3 , the driving structure 59 includes a gear pair 592 arranged on the lead screw 52 and the rotating rod 53, an electromagnetic clutch 591 arranged on the periphery of the lead screw 52 and below the gear pair 592, and a driving member 593 for driving the lead screw 52. The driving member 593 drives the lead screw 52 and the rotating rod 53 simultaneously through the gear pair 592. The electromagnetic clutch 591 is connected in series with the resistance plate 46 and the resistance block 47. However, the electromagnetic clutch 591 transmits torque through a magnetic field, adjusts its magnetic field size to change the mechanical transmission efficiency, and transfers the redundant kinetic energy to the rotating rod 53, enabling the rotating rod 53 to increase the rotational speed and torque accordingly, and correspondingly increasing the knocking frequency and force of the knocking ball 56 in the lever, that is, adjusting the vibration intensity.

[0036] It should be noted that the driving member 593 and the electromagnetic member 37 are separately connected to a PLC controller for control.

[0037] The working principle of this device is as follows:

[0038] In order to solve the problem that the vibration intensity in the prior art is fixed and cannot meet the exhaust requirements of different materials, during the injection molding process of the moving mold 1 and the fixed mold 2 in the closed mold state, the moisture in the material will rapidly vaporize to form gas and enter the cylinder 42 through the exhaust holes 11 and the air outlet pipe 41. In the initial state, the air outlet hole 45 is in a position close to the air outlet pipe 41. Referring to Figure 7, the resistance block 47 is located at the right end of the resistance plate 46. At this time, the resistance value in the circuit where the resistance plate 46 and the resistance block 47 are located is relatively small. Assuming that the moisture content in the material is small, the gas entering the cylinder 42 through the air outlet pipe 41 can be discharged in time through the air outlet hole 45. Then, the position of the resistance block 47 at the right end of the resistance plate 46 can be relatively maintained. The current in the circuit where the resistance plate 46, the resistance block 47, the electromagnetic clutch 591, and the linear drive 32 are located is relatively large. On the one hand, the power of the linear drive 32 is relatively large, so that the moving speed of the injection tube 31 is relatively fast. In addition, in this circuit, it is also connected in series with the DC motor in the screw conveyor device for transporting materials. The injection speed of the material in the injection tube 31 is also relatively fast. On the other hand, referring to Figures 4 to 5 , the engagement strength of the electromagnetic clutch 591 is relatively large. The driving member 593 drives the lead screw 52 at normal power, so that the lead screw 52 drives the moving plate 54, the lever 55, and the knocking ball 56 to rise, and the rising speed is relatively fast. The pitch of the lead screw 52 is the same as that in the linear drive 32, so that the position of the knocking ball 56 matches the liquid level of the material in the cavity. During this process, the lead screw 52 drives the rotating rod 53 to rotate synchronously through the gear pair 592. The rotating rod 53 drives the turntable 57 to rotate. Since the turntable 57 is splined to the rotating rod 53, the turntable 57 rotates and rises at the same time. During the rotation of the turntable 57, one end of the pull rod 58 is reciprocally swung through the cooperation of the limit groove and the limit pin, so that the knocking ball 56 at one end of the lever 55 reciprocally knocks the fixed mold 2 with the hinge joint of the moving plate 54 and the lever 55 as the fulcrum, so that the fixed mold 2 moves and knocks while following the injection progress;

[0039] Once the moisture in the material exceeds the threshold value, the gas entering the cylinder 42 through the air outlet pipe 41 cannot be discharged in time, and the air pressure pushes the cylinder plate 43 to move, driving the resistance block 47 to slide relative to the resistance plate 46. According to the above description of the working principle, at this time, the moving distance of the resistance block 47 relative to the resistance plate 46 is proportional to the resistance value formed by the resistance block 47 and the resistance plate 46 and inversely proportional to the current in the circuit where they are located, so that the injection speed of the injection tube 31 is correspondingly reduced, and the rising speeds of the moving plate 54, the lever 55, and the knocking ball 56 are relatively reduced, slowing down the injection progress. In addition, the engagement strength of the electromagnetic clutch 591 is weakened. It should be noted that the driving member 593 maintains the same power, and the energy output per unit time is constant. According to the law of conservation of energy, the energy transmitted to the lead screw 52 through the electromagnetic clutch 591 is reduced, while the energy transmitted to the rotating rod 53 is increased, so that the rotation speed and torque of the rotating rod 53 relative to the lead screw 52 are increased. Thus, although the material injection speed and the rising speed of the knocking ball 56 are slow, the knocking frequency and knocking force of the knocking ball 56 are increased, realizing the adaptation of the vibration intensity to the moisture in the material.

[0040] Embodiment 2:

[0041] On the basis of the above embodiments, referring toFigure 8 , the injection molding device further includes a demolding assembly 6. The demolding assembly 6 includes a groove 61. The groove 61 includes a sliding groove 611 opened on the inner side of the moving mold 1, an air inlet groove 613 communicated with the sliding groove 611, and an air outlet groove 612 communicated with the air inlet groove 613 and the sliding groove 611. The other end of the air inlet groove 613 is communicated with an electromagnetic component two 63. The electromagnetic component two 63 is controlled by a PLC controller. A plug block 64 is hermetically and slidably connected in the sliding groove 611. A connecting rod 66 is fixed to the side of the plug block 64 away from the cavity. The inner diameter of the connecting rod 66 is relatively small. A sliding plate 67 with ferromagnetism is fixed to the end of the connecting rod 66 away from the plug block 64. It should be noted that the moving mold 1 and the fixed mold 2 also have ferromagnetism, but their ferromagnetism is weaker than that of the sliding plate 67, so that the electromagnetic component two 63 can normally generate a stronger magnetic suction force on the sliding plate 67. An elastic component two 68 is fixed between the sliding plate 67 and the sliding groove 611. The elastic component two 68 can be a spring. An electromagnetic component two 63 is fixed to the inner wall of the sliding groove 611. An elastic delay switch 62 electrically connected to the electromagnetic component two 63 is fixed to the inner wall of the sliding groove 611. The elastic delay switch 62 has a certain telescopic ability. During the contact pressure and continuous compression process of the electromagnetic component two 63, the electromagnetic component two 63 maintains a continuous working state.

[0042] During the injection molding process of the device, the plug block 64 is flush with the inner wall of the cavity and does not affect normal injection molding. Moreover, the resistance of the elastic component two 68 is greater than the injection pressure and will not cause depression to affect injection molding. After the injection molding is completed and the sole product is cooled and solidified, the demolding process is carried out through the demolding assembly 6. Specifically, in order to prevent the plug block 64 from moving towards the cavity by inflating through the air inlet groove 613, a one-way blocking block 65 for blocking the movement of the plug block 64 towards the cavity is fixed to the inner wall of the sliding groove 611. The electromagnetic component two 63 pumps air into the sliding groove 611 through the air inlet groove 613 and pneumatically pushes the sliding plate 67 to compress the elastic component two 68 until the sliding plate 67 contacts the elastic delay switch 62. The electromagnetic component two 63 is energized with a time delay for a preset time. During this preset time, the electromagnetic component two 63 adsorbs the sliding plate 67 under the action of magnetic suction force and maintains its position. During the process of pneumatically pushing the sliding plate 67, the plug block 64 moves away from the cavity but the air outlet groove 612 is not exposed. After the sliding plate 67 drives the plug block 64 to move through the connecting rod 66, the air outlet groove 612 is exposed. Then, the electromagnetic component two 63 supplies air into the cavity through the air inlet groove 613 and the air outlet groove 612 to eject the product, realizing pneumatic demolding.
