Description

Technical Field

[0001] The present invention belongs to the technical field of floor heating panel preparation, and particularly relates to a floor heating panel forming system and method. Background Technique

[0002] During the production process of EPS forming equipment, the raw materials need to be heated to make them expand and form. In the case of producing floor heating panels, when changing from producing 2 pieces per mold to 4 pieces per mold, the following problems exist:

[0003] The burden on the heating system increases: The amount of raw materials to be heated increases significantly. For example, within the same production time, the heating system needs to provide sufficient heat for more EPS raw materials per unit time to ensure their full expansion. This may lead to insufficient heating power, causing the raw materials to not reach the ideal forming temperature, thereby affecting product quality, such as incomplete forming, uneven surface, etc.

[0004] The heating non-uniformity is exacerbated: Due to the change in the mold size and the loading amount, the temperature field distribution in the heating cavity will change. The original heating element layout and power distribution designed for producing 2 pieces per mold may not ensure that the raw materials around each mold cavity can be evenly heated when producing 4 pieces per mold. This may result in inconsistent product quality, with some products having too high or too low density, affecting their physical properties such as heat preservation performance.

[0005] The forming cycle is prolonged: As the number of mold cavities increases, the time for injection, pressure holding, cooling, and demolding and other processes needs to be readjusted. For example, during the injection process, in order to ensure that all 4 mold cavities can be evenly filled, the injection speed may need to be reduced, thereby prolonging the injection time. The pressure holding stage also needs to be appropriately extended to ensure the dimensional accuracy and quality stability of the product. During the cooling process, due to the increase in the number and volume of products, the heat dissipation is relatively slow, and more time is required to make the products reach the demolding temperature. These factors combined make the entire forming cycle prolonged, reducing the production efficiency of the equipment.

[0006] The requirements for the accuracy of mold installation and positioning are higher: The mold for producing 4 pieces per mold has a larger size and a more complex structure, which puts higher requirements on the mold installation and positioning accuracy of the EPS forming equipment. During the installation process, it is necessary to ensure the precise coordination of the mold with components such as the injection system and the mold clamping system of the equipment. For example, the gate position of the mold must be accurately aligned with the injection head, otherwise it will cause uneven injection of raw materials. At the same time, the deviation in the positioning accuracy of the mold will affect the mold clamping quality, and defects such as loose mold clamping and flash may occur, or the product may be damaged during demolding.

[0007] The challenge of equipment operation stability increases: During the operation of the equipment, when four pieces are produced in one mold, the load increases, and the wear and fatigue of each component intensify. For example, the pressure fluctuation of the hydraulic system may become larger due to the change in load, affecting the stability of mold closing and demolding. Mechanical transmission components such as lead screws and chains are prone to loosening and wear under long-term high-load operation, resulting in a decrease in the operation accuracy of the equipment and unstable product quality. Moreover, the vibration of the equipment during production may also become larger due to the increase in the weight of the mold and the product, further affecting the forming quality of the product.

The air supply device is electrically connected to the control system; the air supply pipeline of the air supply device is connected to the air inlet end of the cylinder device, and the cylinder device is electrically connected to the limit switch; the cylinder device is used to drive the mold moving of the mold and adjust the opening die gap width according to the air intake volume and air intake speed of the cylinder device; cylinder devices are fixedly connected to both ends of each mold moving located on both sides of the fixed mold.

[0017] Preferably, the ejector rod extends to the position of the side wall, the reinforcing rib or the boss of the floor heating plate to be formed in the mold cavity facing the fixed mold (the wrapping force is relatively large and the thickness is relatively thick in these areas, and the function of the ejector rod is to provide sufficient ejection force to help the floor heating plate demold).

[0018] Preferably, the length of the ejector rod is 60 cm, and the ejector rod can be ejected or reset within a distance of 20 cm in the mold to ensure that the ejector rod will not interfere with other parts of the mold during the movement process.

[0019] Preferably, a material cylinder and a steam supply device are further provided; the feeding end of the material gun is connected to the material cylinder through a material pipe; the feeding end of the material gun is also externally connected to a compressed air supply device, and the material gun is used to fill the EPS raw material into the mold cavity and fill the mold cavity; the steam supply device is connected to the steam chamber through a steam pipeline; the water inlet pipeline is connected to the water inlet end of the cooling pipeline, and the water outlet end of the cooling pipeline is connected to the drainage pipeline through a plurality of holes evenly distributed on the moving mold.

[0020] Preferably:

[0022] A limit switch for sending a signal indicating that the mold opening is in place to the control system.

[0023] Preferably, the fixed mold is a convex mold, and the moving mold is a concave mold matching the shape of the convex mold.

[0024] The working method of this floor heating plate forming system includes the following steps:

[0025] Assembling the mold: Install the fixed mold, the moving mold, the guide pillar, the traction device, the material gun and the air plug according to the specific structure of the mold; the control system controls the cylinder device to drive the moving mold to move until the fixed mold and the two moving molds are completely closed to form a mold cavity;

[0026] Preheating the mold: Place the installed mold in the steam chamber, and the control system sends a control signal to the steam inlet switch of the steam chamber, and the steam enters the steam chamber to preheat the mold;

[0027] Feeding and Molding: The material gun receives the control signal sent by the control system. The EPS raw material is injected into the mold cavity in the fixed mold through the material gun. The supply amount of the EPS raw material is controlled by the material gun to ensure that the supply amount of the EPS raw material injected into the mold cavity each time is consistent. The material gun can accurately inject the material into various parts of the mold, including some complex shapes and details, making the surface of the floor heating board smoother and flatter, which helps to produce EPS floor heating boards with high dimensional accuracy and uniform density, reducing defects such as deformation and bubbles caused by uneven material supply, and improving the yield rate of the floor heating board. After injecting a set amount of EPS raw material into the mold cavity, the control system controls the material gun to stop feeding. After the EPS raw material expands and forms in the preheated mold for a set time, the water inlet switch and drainage switch of the cooling pipe receive the control signal sent by the control system and open. The cooling water continuously enters the cooling pipe from the water inlet pipeline to cool the mold cavity and then discharges from the drainage pipeline. The EPS raw material forms after standing in the mold cavity for a set time.

[0028] Mold Opening and Demolding: According to the control signal of the control system, by adjusting the air intake amount and air intake speed of the cylinder device, the cylinder device drives the moving mold to move to the set position to adjust the width of the mold opening gap to the set value. When the cylinder device pushes the moving mold to move to the set mold opening gap, the limit switch is triggered. The limit switch sends a mold opening in-place signal to the control system. After receiving the mold opening in-place signal, the control system sends a stop air supply signal to the air supply device. After receiving the stop air supply signal, the air supply device immediately stops supplying air to the cylinder device, and the cylinder device stops moving, thereby accurately controlling the mold opening gap and opening the mold cavity. The cylinder device drives the ejector rod to move to eject the formed floor heating board.

[0029] Drying and Heat Preservation: The steam chamber dries and heat-preserves the demolded floor heating board.

[0030] Exhaust and Removal: The steam discharge switch receives the control signal sent by the control system and opens. The floor heating board forming system exhausts outward, and the dried and formed floor heating board is taken out from the steam chamber.

[0031] The beneficial effects of the present invention are:

[0032] The present invention can drive the mold moving die through a cylinder device, and flexibly adjust the width of the mold opening gap according to the intake air volume and intake air speed of the cylinder device; the fixed mold moving device provided by the present invention is used to link the fixed mold and the moving dies located on both sides of the fixed mold. When the cylinder device drives the moving die of the mold to move, the fixed mold in the middle can move along with the moving moving die; the guide posts and traction devices in the fixed mold moving device are used for precise guiding to ensure the linearity and stability of the fixed mold during the moving process, avoid deviation or shaking, and ensure the accuracy and reliability of the mold during opening and closing; the cylinder device is used to provide sufficient power for the movement of the fixed mold, so that the fixed mold can perform opening and closing operations according to a predetermined trajectory and speed to meet the process requirements during the production process;

[0033] The cylinder device of the present invention can flexibly adjust the magnitude, speed and torque of the provided power according to different working requirements; the ejector rod can evenly apply an ejection force when the mold is opened, and smoothly eject the formed floor heating plate from the mold cavity, avoiding deformation or damage of the floor heating plate during the demolding process, and ensuring the quality integrity of the floor heating plate. The present invention strictly controls the dimensions of the fixed mold and the moving dies, and the fixed mold and the two moving dies respectively located on both sides of the fixed mold can accurately butt and close the mold, and can accurately shape the internal structure and external contour of the floor heating plate, so that the floor heating plate meets strict quality standards.

[0034] In the case of producing floor heating plates from 2 pieces per mold to 4 pieces per mold, the present invention can reduce the burden on the heating system, heat evenly, and does not require readjustment of the time for injection, pressure holding, cooling and demolding and other links.

[0055] Example 2

[0056] A working method of a floor heating board forming system includes the following steps:

[0057] Assemble the mold: Install the fixed mold 1, movable mold 2, guide pillar 13, traction device 14, material gun 3 and air plug 12 according to the specific structure of the mold; The control system controls the cylinder device to drive the movable mold 2 to move until the fixed mold 1 and the two movable molds 2 are completely closed to form the mold cavity 11;

[0058] Preheat the mold: Place the installed mold in the steam chamber 5, and the control system sends a control signal to the steam inlet switch of the steam chamber 5. Steam enters the steam chamber 5 to preheat the mold;

[0059] Feeding and forming: The material gun 3 receives the control signal sent by the control system, and the EPS raw material is injected into the mold cavity 11 in the fixed mold 1 through the material gun 3. The supply amount of the EPS raw material is controlled by the material gun 3 so that the supply amount of the EPS raw material injected into the mold cavity 11 each time is consistent; The material gun can accurately inject the material into various parts of the mold, including some complex shapes and details, making the surface of the floor heating board smoother and flatter, which helps to produce EPS floor heating boards with high dimensional accuracy and uniform density, reducing defects such as deformation and bubbles caused by uneven material supply, and improving the yield rate of the floor heating board; After injecting a set amount of EPS raw material into the mold cavity 11, the control system controls the material gun 3 to stop supplying material; After the EPS raw material expands and forms in the preheated mold for a set time, the water inlet switch and drain switch of the cooling pipe receive the control signal sent by the control system and open. Cooling water continuously enters the cooling pipe from the water inlet pipeline 9 to cool the mold cavity 11 and then drains out from the drain pipeline 10; The EPS raw material forms after standing in the mold cavity 11 for a set time;

[0060] Open the mold and demold: According to the control signal of the control system, by adjusting the air intake amount and air intake speed of the cylinder device, the cylinder device drives the movable mold 2 to move to a set position to adjust the width of the mold opening gap to a set value; When the cylinder device pushes the movable mold 2 to move to the set mold opening gap, the limit switch is triggered, and the limit switch sends a mold opening in-place signal to the control system. After receiving the mold opening in-place signal, the control system sends a stop air supply signal to the air supply device. After receiving the stop air supply signal, the air supply device immediately stops supplying air to the cylinder device, and the cylinder device stops moving, thereby accurately controlling the mold opening gap and opening the mold cavity 11; The cylinder device drives the ejector rod 4 to move to eject the formed floor heating board;

[0063] According to the floor heating panel forming system and working method thereof of the above embodiment 1 and embodiment 2, and Figure 6 and Figure 7 , the floor heating panels and production process have been greatly optimized, as follows:

[0064] (1) Significant reduction in steam energy consumption: After the mold reform, the steam consumption has been greatly optimized for the production of the same number of floor heating panels. Compared with before the reform, the steam consumption can be saved by about 35% under the same output. This is mainly due to the optimization of the mold structure and production process, which greatly improves the utilization rate of steam in the heating process, reduces unnecessary steam loss and waste, and thus brings considerable energy cost savings.

[0065] (2) Effective reduction of electricity consumption: Excellent results have also been achieved in electricity consumption, with electricity consumption being reduced by about 45%. During the design and operation of the new mold, while ensuring normal production, electricity consumption was reduced to the maximum extent, further improving energy efficiency and economic benefits.

[0066] (3) Significant improvement in time efficiency: The output of molds has increased from two pieces per mold to four pieces per mold, while the production time per mold is basically the same as before. This means that the output has doubled in the same period of time. For example, the original daily output was X pieces, and after the reform, the output can reach 1.5X pieces. This significant improvement in efficiency can meet order demand in a shorter time.

[0067] (4) Significant reduction in employee costs: Since the output increased within the same period of time, while the operating procedures and staffing in the production process did not increase significantly, the man-hours required to complete the same output task were significantly reduced. This invisibly reduced cost expenditures and improved the human cost efficiency of the enterprise. The enterprise can invest the saved human cost in other key business areas, such as R&D innovation, market expansion, etc., to further enhance the overall competitiveness of the enterprise.
