Description

Technical Field

[0001] This invention relates to the field of injection molding technology, specifically to an automated one-piece injection molding machine for shoe soles and the injection molding process. Background Technology

[0002] Injection molding of shoe soles is a key process in the footwear industry. Traditional shoe sole injection molding equipment usually adopts a single-station operation mode, that is, the steps of mold closing, injection, cooling, mold opening and part removal are completed in sequence at the same station, resulting in a long production cycle and limited capacity.

[0003] Some existing technologies attempt to introduce a rotary multi-station structure, but in practical applications, the following shortcomings still exist: First, the support and positioning accuracy of the injection station for the mold is insufficient, and the mold is prone to displacement during high-pressure injection, affecting product quality; Second, the mold temperature before injection is difficult to control precisely. If the temperature is too low, the material flowability will be poor and the filling will be insufficient, while if the temperature is too high, the cooling time will be prolonged and the efficiency will be reduced; Third, the demolding process relies on a complex ejection mechanism, which is bulky and has a high failure rate; Fourth, part removal and mold release agent spraying usually need to be done manually or by independent equipment, with limited automation.

[0004] Therefore, it is necessary to provide an automated one-piece injection molding machine and injection molding process for shoe soles to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an automated one-piece molding injection machine for shoe soles and its injection process, so as to solve the technical problems of low production efficiency, insufficient temperature control accuracy, complex demolding mechanism and low degree of automation in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automated one-piece injection molding machine for shoe soles, comprising: A base on which an injection molding assembly is provided, wherein the injection end of the injection molding assembly is connected to a punch, and the punch supplies injection plastic material. A turntable with two die assemblies is provided on it. The turntable is driven by a drive assembly to switch the positions of the two die assemblies between a first station and a second station. The first station is located below the punch, and the second station is located on the opposite side of the first station. A robotic arm, positioned on one side of the second workstation, is used to grab finished products and spray release agent. The turntable has a through groove corresponding to the die assembly; The base is fixed with a first telescopic rod corresponding to the first work station. The telescopic end of the first telescopic rod is provided with a limit support seat, which is used to position the through slot corresponding to the first work station and support the die assembly corresponding to the first work station. The base is provided with a temperature control component corresponding to the second station, which is used to adjust the temperature of the cavity mold component corresponding to the second station so that it reaches the preparation state before injection molding.

[0007] Furthermore, preferably, the temperature control component includes: The second telescopic rod is fixed to the base; A temperature control groove is fixed to the output end of the second telescopic rod; The second temperature control tube is connected to the temperature control tank and is used to provide temperature control liquid to the temperature control tank. The die assembly includes a die base, the die base having at least a die cavity and an ejector pin communicating with the die cavity, the bottom of the ejector pin extending downward to enter the temperature control groove, and the ejector pin being made of a thermally conductive material.

[0008] Furthermore, as a preferred embodiment, a first temperature control tube is provided in the die holder.

[0009] Furthermore, as a preferred embodiment, each of the concave mold cavities is provided with two ejector pins, and a floating top plate is sleeved on the outside of the ejector pins. The floating top plate is configured to generate buoyancy in the liquid to push the ejector pins upward, thereby lifting the molded part.

[0010] Furthermore, as a preferred embodiment, the initial heights of the floating plates on the two ejector pins in the same concave mold cavity are different. When the temperature is controlled using the temperature control tank, the liquid in the temperature control tank gradually increases and gradually decreases after the temperature control is completed.

[0011] Furthermore, as a preferred embodiment, the floating plates on the two ejector pins in the same concave mold cavity are connected to mutual limiting plates. When the two mutual limiting plates are in contact, they are plugged in, so that after the floating plate that comes into contact with the liquid first rises, its corresponding mutual limiting plate can be limited by the other mutual limiting plate, thereby allowing the two to rise synchronously.

[0012] Furthermore, preferably, an annular sealing seat is fixed in the through groove. The sealing seat has an annular groove in the middle. An annular gasket and a plurality of elastic seats in contact with the annular gasket are installed in the annular groove. The elastic seats have through holes. A locking bolt passes through the through holes and is threadedly connected to the sealing seat. The lower part of the locking bolt is tapered. By adjusting the degree of screwing in the locking bolt, the degree of compression of the elastic seat on the annular gasket is adjusted, thereby adjusting the sealing degree of the annular gasket on the temperature control groove.

[0013] Furthermore, preferably, the injection molding assembly includes: A base, on which a height adjustment rod is provided; A slide block is vertically slidably mounted on the base and connected to the adjusting end of the height adjusting rod; An injection head is fixed to the bottom of the slide block, and the injection port of the injection head passes through the punch.

[0014] Furthermore, preferably, the driving component includes: A rotating drum, fixedly passing through the middle of the turntable, is used to guide the first temperature control tube through it; The transmission component is connected to the rotating drum transmission; A power mechanism is used to drive the transmission components.

[0015] This invention also provides an automated one-piece injection molding process for shoe soles, using the aforementioned automated one-piece injection molding machine for shoe soles, comprising the following steps: S1: The temperature of the cavity mold assembly located at the second station is controlled by the temperature control component to bring it to the preparation state before injection molding. S2: Drive the turntable to rotate via the drive component, and transfer the die assembly from the second station to the first station; S3: The first telescopic rod extends, causing the limiting support seat to position the through slot of the first station and support the die assembly; S4: The injection molding assembly supplies material to the die assembly at the first station through the punch to perform injection molding; S5: After injection molding is completed, the first telescopic rod retracts; S6: Drive the turntable to rotate via the drive component, and transfer the die assembly with the molded part from the first station to the second station; S7: The robotic arm picks up the finished product from the second workstation and sprays a release agent onto the die assembly.

[0016] Compared with the prior art, the present invention provides an automated one-piece injection molding machine and injection molding process for shoe soles, which has the following beneficial effects: (1) The present invention uses a rotary dual-station layout to allow the injection molding process and the temperature control / part removal process to be carried out in parallel on two separate stations, which significantly shortens the production cycle and improves equipment utilization.

[0017] (2) By setting a first telescopic rod and a limiting support seat at the first station, the present invention positions the through groove and forms a rigid support for the cavity mold assembly before injection molding, effectively resisting the impact force generated by high pressure injection molding, and ensuring mold closing accuracy and product quality.

[0018] (3) The present invention preheats or cools the die assembly at the second station by using a temperature control component, so that the die assembly is already at the optimal injection temperature when it enters the first station. This not only improves the fluidity of the material and enhances the filling quality, but also avoids the time loss of waiting for the injection station to heat up.

[0019] (4) The present invention utilizes the temperature-controlled liquid in the temperature-controlled tank in conjunction with the ejector pin to achieve precise temperature control of the concave mold cavity, and also achieves buoyancy demolding by means of the buoyancy of the floating top plate in the liquid, simplifying the traditional mechanical ejection mechanism.

[0020] (5) The present invention, through the setting of double ejector pins and floating top plates with different initial heights, and in conjunction with the plug-in limiting structure of the mutual limiting plate, realizes the step-by-step action of the ejector pins and the final synchronous upward movement during the liquid level rise and fall process, thereby improving the demolding effect.

[0022] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms are interchangeable where appropriate; this is merely a way of distinguishing objects with the same attributes in the embodiments of this application. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion, so that a process, method, system, product, or apparatus that comprises a series of elements is not necessarily limited to those elements, but may include other elements not explicitly listed or inherent to those processes, methods, products, or apparatuses.

[0023] Example: See Figures 1 to 9 This embodiment provides an automated one-piece injection molding machine for shoe soles, including a base 1, a turntable 2, a drive assembly 3, a cavity mold assembly 4, a first telescopic rod 5, a temperature control assembly 6, a punch 7, an injection molding assembly 8, and a robotic arm 9.

[0024] The base 1 serves as the load-bearing foundation of the entire machine. It is made of steel or cast iron and has sufficient rigidity and stability. An injection molding assembly 8 is fixedly installed on the base 1. A punch 7 is connected below the injection end of the injection molding assembly 8. The injection molding assembly 8 supplies injection plastic to the die assembly 4 through the punch 7 to complete the injection molding process.

[0025] The turntable 2 is disc-shaped or symmetrical, with two die assemblies 4 mounted on its upper part. The two die assemblies 4 are symmetrically arranged around the rotation center of the turntable 2. The turntable 2 is driven by the drive assembly 3 to rotate around a vertical axis, thereby changing the position of the two die assemblies 4 between a first station and a second station. The first station is located directly below the punch 7 and is used to perform injection molding operations; the second station is located on the opposite side of the first station and is used to perform operations such as temperature control, part removal, and mold release agent spraying.

[0026] The robotic arm 9 is installed on one side of the second station. It can be a multi-axis industrial robotic arm. The end effector of the robotic arm 9 integrates a suction cup and a spraying device. After the molded shoe sole is picked up and removed at the second station, a release agent is sprayed onto the cavity surface of the mold assembly 4 to prepare for the next injection molding.

[0027] A through groove 21 is provided on the turntable 2 corresponding to the position of each die assembly 4, and the through groove 21 penetrates the upper and lower surfaces of the turntable 2.

[0028] A first telescopic rod 5 corresponding to the first working position is fixedly installed on the base 1. The first telescopic rod 5 is preferably a hydraulic cylinder or a pneumatic cylinder. A limit support seat 10 is installed on the telescopic end (upper end) of the first telescopic rod 5. After the die assembly 4 rotates with the turntable 2 to reach the first working position, the first telescopic rod 5 extends, so that the limit support seat 10 passes through the through groove 21 and abuts against the bottom of the die assembly 4. The limit support seat 10 achieves precise positioning of the turntable 2 and the die assembly 4 by cooperating with the through groove 21, and provides vertical rigid support for the die assembly 4 to withstand the high pressure generated during injection molding.

[0029] A temperature control component 6 is installed on the base 1 at the position corresponding to the second station. When the die assembly 4 is in the second station, the temperature control component 6 adjusts the temperature of the die assembly 4 to reach the optimal temperature state required before injection molding. The temperature adjustment can adopt either heating mode or cooling mode according to actual needs.

[0030] Specifically, the temperature control assembly 6 includes a second telescopic rod 61, a temperature control groove 62, and a second temperature control pipe 63. The second telescopic rod 61 is fixed to the base 1, and its extension and retraction direction is vertical. The temperature control groove 62 is fixed to the output end of the second telescopic rod 61 and can rise and fall with the extension and retraction of the second telescopic rod 61. The second temperature control pipe 63 is connected to the temperature control groove 62 and is used to introduce a temperature-controlled liquid (such as hot water, hot oil, or coolant) into the temperature control groove 62 to regulate the temperature inside the temperature control groove 62.

[0031] In this embodiment, the die assembly 4 includes a die base 42, within which a die cavity corresponding to the shape of a shoe sole is formed. An ejector pin 43 is connected to the bottom of the die cavity, with its lower end extending downwards and passing through the bottom of the die base 42. The external structures of the ejector pin 43, such as the return spring, are not described in detail here. When the die assembly 4 is in the second position and the second telescopic rod 61 extends, the temperature control groove 62 rises, causing the lower part of the ejector pin 43 to extend into the temperature control groove 62 and be immersed in the temperature-controlled liquid. The ejector pin 43 is made of a thermally conductive material (such as copper, aluminum, or a thermally conductive alloy), which can efficiently transfer the heat or cold of the liquid in the temperature control groove 62 to the die cavity, thereby achieving auxiliary temperature control of the mold cavity.

[0032] Of course, the die holder 42 also has basic temperature control, and a first temperature control tube 41 can be installed inside the die holder 42. The first temperature control tube 41 can be pre-embedded in the side wall or bottom of the die holder 42, and the temperature of the die holder 42 body can be adjusted by introducing a temperature control medium.

[0033] Ideally, two ejector pins 43 are installed in each concave mold cavity, evenly distributed within the cavity to ensure balanced ejection force. Each ejector pin 43 is fitted with a floating top plate 44. The floating top plate 44 is made of a material with a density less than the temperature-controlled liquid (such as foamed plastic, hollow metal shell, etc.), enabling it to generate sufficient buoyancy in the temperature-controlled liquid. When the liquid level in the temperature-controlled tank 62 rises, the floating top plate 44 is driven upwards by buoyancy, pushing the ejector pins 43 upwards, thereby lifting the molded part in the cavity and achieving demolding. This buoyancy-based demolding method avoids complex mechanical ejection linkages and drive sources, resulting in a simple and reliable structure.

[0034] Preferably, the initial heights (i.e., installation heights relative to the bottom of the temperature control tank 62) of the floating plates 44 on the two ejector pins 43 in the same concave mold cavity are different. During the temperature control stage, the liquid in the temperature control tank 62 gradually increases from the initial liquid level. The floating plate 44 with the lower initial height contacts the liquid first and begins to rise, corresponding to the ejector pin 43 moving upward a short distance first. As the liquid level continues to rise, the other floating plate 44 then contacts the liquid and begins to rise. After temperature control is completed, the liquid in the temperature control tank 62 is gradually discharged, and the liquid level drops. This step-by-step rising method makes the demolding process smoother.

[0035] Furthermore, each of the two floating roof plates 44 is connected to an interlocking plate 45. The two interlocking plates 45 are arranged opposite each other and engage in a plug-in manner when they come into contact. After the floating roof plate 44 that first comes into contact with the liquid rises to a certain height, its corresponding interlocking plate 45 contacts the other interlocking plate 45 and forms an interlocking limit. At this time, the latter interlocking plate 45 constrains the former interlocking plate 45, thus preventing the first floating roof plate 44 from moving further upward independently. Subsequently, under the buoyancy of the liquid on the latter floating roof plate 44, the two floating roof plates 44 and the corresponding ejector pins 43 rise synchronously, ensuring that the molded part is finally smoothly ejected from the concave mold cavity.

[0036] In this embodiment, an annular sealing seat 22 is fixedly installed on the inner wall of the through groove 21. An annular groove is formed in the middle of the sealing seat 22, with its opening facing the central axis of the through groove 21. An annular gasket 24 (such as a rubber gasket, fluororubber gasket, or polyurethane gasket, etc., an elastic sealing material) is installed inside the annular groove, and the inner circumferential surface of the annular gasket 24 can contact the outer wall of the temperature control groove 62 extending into the through groove 21. Multiple circumferentially distributed elastic seats 23 are also installed inside the annular groove, with the inner side of the elastic seats 23 contacting the outer circumferential surface of the annular gasket 24. Each elastic seat 23 has a radially extending through hole, and a locking bolt 25 passes through this through hole from the outside and is threadedly connected to the sealing seat 22. The lower part of the locking bolt 25 (the side closest to the annular gasket 24) is tapered. When the locking bolt 25 is screwed in, its conical surface presses against the elastic seat 23. After the elastic seat 23 is deformed by the pressure, it further presses against the ring gasket 24, which increases the clamping force of the ring gasket 24 on the outer wall of the temperature control groove 62 and improves the sealing degree. Conversely, when the locking bolt 25 is screwed out, the sealing degree decreases.

[0037] In this embodiment, the injection molding assembly 8 includes a base 81, a slide 82, and an injection head 83. The base 81 is mounted on the base 1 and is equipped with a height adjustment rod (which may be a lead screw, hydraulic rod, etc.). The slide 82 is slidably mounted on the base 81 vertically and is connected to the adjustment end of the height adjustment rod. The vertical position of the slide 82 can be changed by adjusting the height adjustment rod. The injection head 83 is fixed to the bottom of the slide 82, and its injection port passes downward through the injection channel of the punch 7 to inject molten plastic into the cavity of the die.

[0038] In this embodiment, the drive assembly 3 includes a rotating drum 31, a transmission component 32, and a power mechanism 33. The rotating drum 31 is fixedly inserted through the central hole of the turntable 2, coaxially arranged with the turntable 2, and rotates synchronously. The rotating drum 31 has an axial through hole in the middle, through which the first temperature control pipe 41 and other pipes and cables can pass, preventing the pipes from getting tangled during rotation. The transmission component 32 (such as a gear, synchronous pulley, or sprocket) is connected to the outer periphery of the rotating drum 31 for transmission. The power mechanism 33 (such as a servo motor or hydraulic motor) is connected to the transmission component 32, and drives the rotating drum 31 and the turntable 2 to rotate by driving the transmission component 32, thereby realizing the precise position switching of the two die assemblies 4 between the first and second workstations.

[0039] The automated one-piece injection molding process for shoe soles provided in this embodiment uses the aforementioned injection molding machine and includes the following steps: S1: When a cavity mold assembly 4 is in the second station, the second telescopic rod 61 extends, causing the temperature control tank 62 to rise and the lower part of the ejector pin 43 to extend into the temperature control tank 62. A temperature-controlled liquid with a preset temperature is introduced into the temperature control tank 62 through the second temperature control pipe 63. Heat or cold energy is conducted to the cavity mold cavity via the ejector pin 43, gradually bringing the cavity mold assembly 4 to a pre-injection molding state (e.g., preheating to a preset temperature range). Simultaneously, the robotic arm 9 can perform operations such as picking up the part and spraying release agent on the cavity mold assembly 4, after which the second telescopic rod 61 resets.

[0040] S2: The turntable 2 is driven to rotate 180° via the power mechanism 33, transmission component 32, and rotating cylinder 31, thereby transferring the temperature-controlled die assembly 4 from the second station to the first station, located directly below the punch 7. At the same time, the die assembly 4, originally located in the first station, is transferred to the second station.

[0041] S3: The first telescopic rod 5 extends, the limiting support seat 10 passes through the through groove 21 and positions the through groove 21, and at the same time the upper end face of the limiting support seat 10 abuts against the bottom of the die assembly 4 to form a rigid support.

[0042] S4: The height adjustment lever drives the slide block 82, together with the injection head 83, to move downwards. The injection port of the injection head 83 passes through the punch 7 and enters the injection port of the cavity. The injection assembly 8 supplies molten injection material to the cavity through the punch 7, completing the injection filling.

[0043] S5: After injection molding is completed and after necessary pressure holding and cooling, the first telescopic rod 5 retracts and the limiting support seat 10 disengages from the die assembly 4.

[0044] S6: Drive the turntable 2 to rotate 180° again via the drive component 3, and transfer the die assembly 4 with the molded part from the first station to the second station.

[0045] S7: At the second station, the second telescopic rod 61 extends, causing the liquid level in the temperature-controlled tank 62 to rise. Under buoyancy, the floating top plate 44 pushes the ejector pin 43 upwards, ejecting the molded part from the concave mold cavity. The robotic arm 9 picks up the ejected product and removes it, then sprays a release agent onto the surface of the concave mold cavity. The demolded liquid is gradually discharged from the temperature-controlled tank 62, the second telescopic rod 61 resets, and the floating top plate 44 and ejector pin 43 return to their original positions, preparing for the next cycle.

[0046] By repeating steps S1 to S7, continuous automated production of shoe soles can be achieved.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
