Description

Technical Field

[0001] This invention belongs to the field of injection molding machine technology, specifically relating to a high-efficiency and energy-saving molding machine and its usage method. Background Technology

[0002] Tableware refers to non-edible utensils that come into direct contact with food during meals, used to assist in the distribution or consumption of food. Tableware can be classified by material as follows: ceramic tableware, glass tableware, enamel tableware, wooden tableware, copper tableware, iron tableware, aluminum tableware, alloy tableware, stainless steel tableware, melamine tableware, plastic tableware, antibacterial tableware, and disposable tableware, etc.

[0003] Commonly used plastic tableware is primarily made from polyethylene and polypropylene. These are non-toxic plastics recognized by health authorities in most countries. Sugar boxes, tea trays, rice bowls, water jugs, baby bottles, and other similar items on the market are made of this type of plastic. In the processing and production of plastic tableware, injection molding is typically used.

[0004] The authorized publication number "CN106042334B" describes "a high-efficiency and energy-saving plastic hollow molding machine, including a fixed table and a movable table. The movable table moves relative to the fixed table. Two parallel hinge frames are symmetrically arranged on both sides of the movable table. Each parallel hinge frame includes a first hinge rod and a second hinge rod arranged in parallel longitudinal directions. One end C of the first hinge rod is rotatably hinged to the movable table. The second hinge rod is rotatably connected to the movable table through a rotating shaft D. One end A of the second hinge rod extends upwards towards the movable table and is rotatably hinged to the other end B of the first hinge rod through a third hinge rod, which is parallel to the horizontal plane. The other end E of the second hinge rod extends downwards towards the movable table. Templates are respectively connected to the opposite sides of the two third hinge rods on the two parallel hinge frames. A horizontally arranged telescopic mechanism is connected between the other ends E of the two second hinge rods on the two parallel hinge frames. It also includes a servo motor, the output shaft of which is connected to the movable table through a moving swing arm assembly. Its structure is more reasonable and can achieve high-efficiency and energy-saving production."

[0005] The aforementioned patent utilizes a four-point hinge structure (ABCD), with the line connecting ABCD forming a standard parallelogram. Driven by a telescopic mechanism, the first and second hinge rods tilt simultaneously, maintaining parallelism regardless of the tilt angle. When the telescopic mechanism activates, the two templates on the two third hinge rods close. This structure, without tie rods, guide pillars, or guide rails, minimizes friction. In practical applications, existing molding machines use cooling water to cool the templates during injection molding for rapid cooling and molding of tableware parts. However, the hot water generated during this process is discharged or collected and discharged through a heat exchanger, resulting in low heat utilization efficiency, heat waste, and reduced energy efficiency. Therefore, we propose a highly efficient and energy-saving molding machine and its application method. Summary of the Invention

[0020] In a preferred embodiment of the present invention, the PLC control box is fixed to the side of the mounting bracket.

[0021] A method for using a high-efficiency and energy-saving molding machine includes the following steps:

[0022] S1, Injection Molding:

[0023] The material is poured into the heating cylinder through the feed hopper. The heating cylinder heats the material. The motor is started through the PLC control box. The output of the motor drives the auger to rotate. The auger squeezes the molten material into multiple injection tubes through the rotation. The molten material is pushed into the space between the fixed mold plate and the movable mold plate through the multiple injection tubes and multiple injection holes to achieve injection molding.

[0024] S2, Cooling and Curing:

[0025] The heat exchanger draws cooling water from the water tank through the water supply pipe, and introduces the cooling water into the cooling tank through the two-way connector to cool the two movable templates. The cooling water is introduced into the two cooling pipes through four one-way connectors and four heat collection pipes to cool the two fixed templates, thereby achieving cooling and solidification of the tableware plastic parts between the two fixed templates and the movable templates.

[0026] S3, Preheating:

[0027] The hot water generated during the cooling and solidification process is returned to the heat exchanger, where it is compressed and heated. The heat generated is concentrated by the heat exchanger built into the heat exchanger and guided to the preheating tube through two primary heat pipes. The preheating tube heats the material at one end of the heating cylinder, avoiding heat waste and achieving preheating of the material.

[0028] S4, Applying pressure to drive:

[0029] During the heat exchange process inside the heat exchanger, the generated expanding water vapor is introduced into the high-pressure gas tank through multiple one-way pipes to achieve one-way pressurization in the high-pressure gas tank. When the pressure in the high-pressure gas tank reaches the driving pressure, the connection between the two air guide pipes is controlled by two one-way electronic valves, so that the water vapor in the two air guide pipes is introduced into two cylinders. The two cylinders push the two sliders to move, thereby achieving the pressurization and pushing of the two movable templates.

[0030] S5, Quick Demolding:

[0031] Driven by two cylinders, two sliders move, pushing four push-pull rods to move. These rods then push four sliding blocks within four tracks. The sliding blocks move two movable templates away from two fixed templates. During the movement of the two movable templates, in the single-set demolding mechanism, the movable templates first move two telescopic rods, which pull a reset plate. This reset plate then pushes a second push rod, which pushes one side of the tableware part from its groove, achieving demolding on one side. Next, as the movable template approaches the fixed frame, the fixed frame pushes a push plate. This push plate counteracts the compression of multiple first springs, pushing multiple first push rods from their grooves into the movable template. The push rods then push the tableware part out of the movable template, achieving demolding on the other side and completing the rapid demolding of the tableware part.

[0032] Compared with the prior art, the beneficial effects of the present invention are:

[0033] 1. In this scheme, during the heat exchange process in the heat exchanger, the generated expanding water vapor is introduced into the high-pressure gas tank through multiple unidirectional conduits, achieving unidirectional pressurization within the high-pressure gas tank. When the pressure inside the high-pressure gas tank reaches the driving pressure, two unidirectional electronic valves control the connection of two air guide pipes, allowing the water vapor in the two air guide pipes to be introduced into two cylinders. The two cylinders then drive two sliders to move, thereby pressurizing and pushing the two movable templates to move. By collecting heat from the hot water, high-pressure gas is provided to the two cylinders, converting thermal energy into kinetic energy to power the movement of the two movable templates. This also collects the heat generated during the cooling of the plastic tableware, improving thermal energy utilization efficiency, avoiding heat waste, and enhancing the energy-saving effect of the device.

[0034] 2. In this solution, the preheating pipe is used to heat one end of the heating cylinder, preheating the material in advance. Two primary heat pipes are used to connect the heat exchanger and the preheating pipe, forming a loop between the preheating pipe, the heat exchanger, and the two primary heat pipes. This loop applies heat to the heating cylinder, preheating the material inside. By collecting hot water, the collected heat is used to preheat the material. While using electricity for heating, the solution ensures uniform temperature inside the heating cylinder, preventing material clumping and thus avoiding a decrease in the yield of tableware plastic parts, thereby improving the product quality of tableware plastic parts.

[0035] 3. In this solution, in each linkage assembly, the movement of the slider drives the movement of two push-pull rods. Two limiting grooves guide the movement of the slider through sliding engagement with two limiting blocks. Two sliding blocks limit and guide the movement of the movable template through sliding engagement with two tracks. Two push-pull rods are used to pull and push the movement of the two sliding blocks, thereby moving the movable template. Under the push of two cylinders, the two sliders move, pushing the movement of four push-pull rods, so that the four push-pull rods push the four sliding blocks to move within the four tracks. The four sliding blocks slide with the four tracks, pushing the two movable templates away from the two fixed templates, thereby moving the two fixed templates. Within the device, two sets of linkage assemblies move the two movable templates simultaneously, processing two sets of tableware plastic parts, thus improving the production efficiency of tableware plastic parts.

[0036] 4. In this solution, cooling water is introduced into the cooling tank through a two-way connector to cool the two movable templates, achieving rapid cooling of one side of the tableware plastic part. Cooling water is introduced into two cooling pipes through four one-way connectors and four heat collection pipes to cool the two fixed templates, achieving rapid cooling of the other side of the tableware plastic part. By cooling the two fixed templates and the movable templates, the tableware plastic part is cooled on both sides, accelerating the cooling and solidification of the tableware plastic part. At the same time, rapid cooling generates a large amount of hot water in a short time, providing sufficient heat energy for the high-pressure gas and heat exchanger in the high-pressure gas tank, ensuring rapid heat circulation and reducing heat loss.

[0037] 5. In this solution, in the single-unit demolding mechanism, the movable template first moves two telescopic rods, which pull the reset plate, causing the reset plate to push the second push rod. The second push rod pushes one side of the tableware plastic part from the second push rod slot, achieving demolding of one side of the tableware plastic part. Then, as the movable template approaches the fixed frame, the fixed frame pushes the push plate, which counteracts the compression of multiple first springs. The push plate pushes multiple first push rods, causing the multiple first push rods to be pushed into the movable template from multiple first push rod slots. The multiple first push rods push out the tableware plastic part from the movable template, achieving demolding of the other side of the tableware plastic part, thus completing the rapid demolding of the tableware plastic part.

The four sliding blocks 42 slide with the four tracks 23, pushing the two movable templates 5 away from the two fixed templates 4, thereby moving the two fixed templates 4.

Two one-way electronic valves 45 are provided, and the two one-way electronic valves 45 are fixedly connected to the circumferential surface of the two air guide pipes 44.

[0068] In this invention, a high-pressure gas tank 43 is used to store high-pressure gas. The high-pressure gas tank 43 has a built-in electronic pressure valve to trigger the opening of two one-way electronic valves 45. Two mounting plates 24 are used to fix two cylinders 25. The two cylinders 25 move two sliders 28 through changes in internal and external air pressure. Two air guide pipes 44 are used to introduce the high-pressure gas from the high-pressure gas tank 43 into the two cylinders 25. The two one-way electronic valves 45 control the connection between the two air guide pipes 44 and the two cylinders 25. During the heat exchange process in the heat exchanger 39, the generated expanding water vapor is introduced into the high-pressure gas tank 43 through multiple one-way pipes, achieving high pressure... One-way pressurization is applied inside the gas tank 43. When the pressure inside the high-pressure gas tank 43 reaches the driving pressure, the connection between the two air guide pipes 44 is controlled by two one-way electronic valves 45, so that the water vapor in the two air guide pipes 44 is introduced into the two cylinders 25. The two cylinders 25 push the two sliders 28 to move, thereby achieving pressurized pushing of the two movable templates 5. By collecting the heat in the hot water, high-pressure gas is provided to the two cylinders 25, converting thermal energy into kinetic energy, providing power for the movement of the two movable templates 5. The heat generated when the plastic tableware is cooled is collected, improving the thermal energy utilization efficiency, avoiding heat waste, and improving the energy-saving effect of the device.

[0069] In this embodiment, the preheating component includes a preheating pipe 37 and a primary heat pipe 40.

There are two primary heat pipes 40, which are fixedly connected to the upper side of the preheating pipe 37. Both primary heat pipes 40 are connected to the heat exchanger 39.

[0070] In this invention, the preheating pipe 37 is used to heat one end of the heating cylinder 32, preheating the material in advance. The two primary heat pipes 40 are used to connect the heat exchanger 39 and the preheating pipe 37, so that the preheating pipe 37, the heat exchanger 39 and the two primary heat pipes 40 form a loop, attaching heat to the heating cylinder 32 to preheat the material inside the heating cylinder 32. By collecting hot water, the collected heat is used to preheat the material. While using electricity to heat the heating cylinder 32, the temperature inside the heating cylinder 32 is kept uniform, avoiding material clumping inside the heating cylinder 32. This avoids a decrease in the yield of tableware plastic parts due to material clumping and improves the product quality of tableware plastic parts.

[0076] The following is a brief description of the working process or usage method of a high-efficiency and energy-saving molding machine provided in this embodiment:

[0077] A method for using a high-efficiency and energy-saving molding machine includes the following steps:

[0078] S1, Injection Molding:

[0079] The material is poured into the heating cylinder 32 through the feed hopper 33. The heating cylinder 32 heats the material. The motor 35 is started through the PLC control box 48. The output end of the motor 35 drives the auger 36 to rotate. The auger 36 squeezes the molten material into multiple injection tubes 34 through the rotation. The molten material is pushed into the space between the fixed template 4 and the movable template 5 through the multiple injection tubes 34 and multiple injection holes 17 to achieve injection molding.

[0080] S2, Cooling and Curing:

[0081] The heat exchanger 39 draws cooling water from the water tank 47 through the water supply pipe 46, and introduces the cooling water into the cooling tank 50 through the two-way connector 20 to cool the two movable templates 5. The cooling water is introduced into the two cooling pipes 21 through the four one-way connectors 22 and the four heat collection pipes 41 to cool the two fixed templates 4, thereby achieving the cooling and solidification of the tableware plastic parts between the two fixed templates 4 and the movable templates 5.

[0082] S3, Preheating:

[0083] The hot water generated during the cooling and solidification process flows back to the heat exchanger 39, where it is compressed and heated. The heat generated is concentrated by the heat exchanger built into the heat exchanger 39 and guided to the preheating pipe 37 through two primary heat pipes 40. The preheating pipe 37 heats the material at one end of the heating cylinder 32, avoiding heat waste and achieving preheating of the material.

[0084] S4, Applying pressure to drive:

[0085] During the heat exchange process in the heat exchanger 39, the generated expanding water vapor is introduced into the high-pressure gas tank 43 through multiple one-way pipes, thereby achieving one-way pressurization in the high-pressure gas tank 43. When the pressure in the high-pressure gas tank 43 reaches the pushing pressure, the connection of the two air guide pipes 44 is controlled by two one-way electronic valves 45, so that the water vapor in the two air guide pipes 44 is introduced into the two cylinders 25. The two cylinders 25 push the two sliders 28 to move, thereby achieving the pressurization and pushing of the two movable templates 5.

[0086] S5, Quick Demolding:

[0087] Driven by the two cylinders 25, the two sliders 28 move, pushing the four push rods 30 to move. This causes the four push rods 30 to push the four sliding blocks 42 within the four tracks 23. The four sliding blocks 42 move the two movable templates 5 away from the two fixed templates 4. During the movement of the two movable templates 5, in the single-set demolding mechanism, the movable templates 5 first drive the two telescopic rods 13 to move. The two telescopic rods 13 pull the reset plate 14, causing the reset plate 14 to push the second push rod 15. 5. Push one side of the tableware plastic part from the second push rod groove 16 to demold one side of the tableware plastic part. Then, as the movable template 5 approaches the fixed frame 10, the fixed frame 10 pushes the push column plate 7. The push column plate 7 counteracts the compression of multiple first springs 9. The push column plate 7 pushes multiple first push rods 8, so that multiple first push rods 8 are pushed from multiple first push rod grooves 6 into the movable template 5. Multiple first push rods 8 push the tableware plastic part out of the movable template 5, realizing the demolding of the other side of the tableware plastic part, and completing the rapid demolding of the tableware plastic part.
