Abstract
Description
Technical Field
[0001] This utility model relates to the field of wood-plastic mold technology, and in particular to an embedded heating element mounting structure for wood-plastic molds. Background Technology
[0002] Wood-plastic molds are used to produce wood-plastic products. They are typically made of high-quality stainless steel, forged, heat-treated, and then electrically processed. Wood-plastic materials are resistant to corrosion, water, and decay, and will not rot, deform, or be attacked by pests such as ants and termites. Wood-plastic products made from these molds are widely used in outdoor landscaping, architectural decoration, and other fields.
[0003] When wood-plastic composite molds are used for extrusion, heating components are needed to heat the raw materials. Existing technologies utilize embedded heating elements to heat the wood-plastic composite mold. However, since the mold cavity typically has multiple surfaces, embedding the heating element from one side can result in the back of the cavity being difficult to heat, affecting the uniformity of heating. Therefore, an improved embedded heating element mounting structure for wood-plastic composite molds is proposed. Utility Model Content
[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.
[0005] Therefore, one objective of this utility model is to propose an embedded heating element installation structure for wood-plastic molds to solve the problems mentioned in the background art and overcome the shortcomings of the prior art.
[0006] To achieve the above objectives, one embodiment of this utility model provides an embedded heating element mounting structure for a wood-plastic mold, including a mold body, a cavity within the mold body, an embedding cavity within the mold body, a heating component inserted into the embedding cavity, a handle fixedly connected to the top of the heating component, a toothed plate fixedly connected to the embedding cavity, a storage cavity within the bottom of the heating component, a drive shaft rotatably connected to the storage cavity, a gear fixedly connected to the drive shaft and meshing with the toothed plate, a slider threadedly connected to the drive shaft, a guide rod fixedly connected to the storage cavity and inserted into the slider, a limiting groove formed on the side of the storage cavity, limiting blocks within the limiting grooves on both sides of the slider, and heating plates provided on the inner side of the heating component and the top surface of the slider.
[0007] Preferably, in any of the above embodiments, the cavity is located at the center of the mold body, and the heating component adopts an inverted U-shaped structure.
[0008] The above technical solution employs the following: the mold body provides a space to accommodate the wood-plastic composite material, and a cavity is formed within it. During extrusion, the formed wood-plastic composite product is extruded from the cavity. The cavity is located in the middle of the mold body, facilitating the installation and arrangement of the heating component. The embedded cavity provides installation space for the heating component, which is used to heat the wood-plastic composite material. The heating component adopts an inverted U-shaped structure, allowing it to directly rely on its inner wall to provide an installation platform for the heating plate, providing multi-faceted heating for the wood-plastic composite material.
[0009] Preferably, as described in any of the above embodiments, the top of the mold body is provided with a slot, and the heating component is provided with a plug rod that is inserted into the slot.
[0010] The above technical solution involves creating a slot on the mold body and attaching a rod to the heating component. The rod is inserted into the slot on the mold body when the heating component is inserted into the embedding cavity. The rod and the slot can lock the heating component and prevent it from shifting.
[0011] Preferably, in any of the above solutions, the drive shaft is located in the middle of the storage cavity, and the bottom of the heating assembly has two storage cavities.
[0012] The above technical solution involves: a handle on the heating component for easy gripping and operation; and a storage cavity at the bottom of the heating component to house the sliders. These two storage cavities provide storage space for two sets of sliders, allowing them to converge towards the center from different directions to heat the cavity.
[0013] Preferably, in any of the above solutions, the bottom surface of the slider is provided with a plurality of balls, and the length of the slider is less than the length of the receiving cavity.
[0014] The above technical solution works as follows: When the heating component enters the embedding cavity, the toothed plate enters the receiving cavity and drives the drive shaft to rotate via gears. Under the constraint of the guide rod, the drive shaft pushes the slider to move horizontally, causing the slider to move out of the receiving cavity. Ball bearings are installed at the bottom of the slider; these ball bearings reduce the friction between the slider and the inner wall of the receiving cavity, making the slider's movement smoother.
[0015] Preferably, any of the above solutions involves a plurality of guide rods, which are symmetrically arranged on the outside of the drive shaft.
[0016] Preferably, in any of the above solutions, a limiting groove is provided on both sides of the receiving cavity, and a limiting block is provided on both sides of the slider.
[0017] The above technical solution employs a guide rod to constrain the slider. A symmetrical arrangement of several guide rods facilitates the slider's balance and stability. A limiting groove is created within the receiving cavity, which, in conjunction with a limiting block on the side of the slider, constrains the slider and prevents it from completely detaching from the receiving cavity. Setting limiting grooves and limiting blocks on both sides further enhances the stability of the restraint effect.
[0018] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: 1. The embedded heating element installation structure of this wood-plastic mold, through the setting of components such as a toothed plate, a receiving cavity, a drive shaft, gears, a slider, a guide rod, a limiting groove, and a limiting block, allows the heating element to be inserted into the embedded cavity. The toothed plate enters the receiving cavity, and the gear drives the drive shaft to rotate. Under the constraint of the guide rod, the drive shaft pushes the slider to move horizontally, causing the slider to move out of the receiving cavity. The slider drives the heating plate on it to move to the bottom of the cavity, cooperating with the heating plate inside the heating element to heat the cavity from multiple directions, making the heating effect more uniform and excellent.
[0019] 2. The embedded heating element mounting structure of this wood-plastic mold features an inverted U-shaped heating component, allowing it to directly rely on its inner wall to provide a mounting platform for the heating plate, providing multi-faceted heating for the wood-plastic material. Ball bearings are installed at the bottom of the slider, reducing friction between the slider and the inner wall of the receiving cavity, resulting in smoother slider movement. A limiting groove is provided within the receiving cavity, which, in conjunction with limiting blocks on the side of the slider, constrains the slider, preventing it from completely detaching from the receiving cavity. Limiting grooves and limiting blocks are provided on both sides to improve the stability of the restraint effect.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0025] like Figures 1-4 As shown, this utility model includes a mold body 1, a cavity 2 inside the mold body 1, an embedding cavity 3 inside the mold body 1, a heating component 4 inserted into the embedding cavity 3, a handle 5 fixedly connected to the top of the heating component 4, a toothed plate 6 fixedly connected to the embedding cavity 3, a storage cavity 7 inside the bottom of the heating component 4, a drive shaft 8 rotatably connected to the storage cavity 7, a gear 9 fixedly connected to the drive shaft 8 that meshes with the toothed plate 6, a slider 10 threadedly connected to the drive shaft 8, a guide rod 11 fixedly connected to the storage cavity 7 and inserted into the slider 10, a limiting groove 12 opened on the side of the storage cavity 7, limiting blocks 13 located in the limiting groove 12 on both sides of the slider 10, and heating plates provided on the inner side of the heating component 4 and the top surface of the slider 10.
[0026] Example 1: Cavity 2 is located at the center of mold body 1, and heating component 4 adopts an inverted U-shaped structure. Mold body 1 provides a space to accommodate wood-plastic composite material, and cavity 2 is provided inside it. During extrusion, the formed wood-plastic composite product is extruded from cavity 2. Cavity 2 is located in the middle of mold body 1, which facilitates the installation and arrangement of heating component 4. Embedded cavity 3 provides installation space for heating component 4, which is used to heat the wood-plastic composite material. Heating component 4 adopts an inverted U-shaped structure, which allows it to directly rely on its inner wall to provide an installation platform for the heating plate, providing multi-faceted heating for the wood-plastic composite material.
[0027] A slot is provided on the top of the mold body 1, and a plug is provided on the heating component 4 to be inserted into the slot. The slot on the mold body 1, in conjunction with the plug on the heating component 4, allows the plug to be inserted into the slot on the mold body 1 when the heating component 4 is inserted into the embedding cavity 3. The plug and the slot can lock the heating component 4 to prevent displacement.
[0028] Example 2: The drive shaft 8 is positioned in the middle of the storage cavity 7, and two storage cavities 7 are formed at the bottom of the heating assembly 4. A handle 5 is provided on the heating assembly 4 for easy gripping and operation. The storage cavities 7 at the bottom of the heating assembly 4 provide storage space for the sliders 10. The two storage cavities 7 provide storage space for two sets of sliders 10, allowing the sliders 10 to move towards the center from different directions to heat the cavity 2.
[0029] The bottom surface of slider 10 is provided with several ball bearings, and the length of slider 10 is less than the length of the receiving cavity 7. When the heating component 4 enters the embedding cavity 3, the toothed plate 6 enters the receiving cavity 7 and drives the drive shaft 8 to rotate via the gear 9. Under the constraint of the guide rod 11, the drive shaft 8 pushes slider 10 to move horizontally, causing slider 10 to move out of the receiving cavity 7. The ball bearings at the bottom of slider 10 reduce the friction between slider 10 and the inner wall of the receiving cavity 7, making the movement of slider 10 smoother.
[0030] Example 3: Several guide rods 11 are symmetrically arranged on the outside of the drive shaft 8. Limiting grooves 12 are provided on both sides of the receiving cavity 7, and limiting blocks 13 are provided on both sides of the slider 10. The guide rods 11 are used to constrain the slider 10. The symmetrical arrangement of several guide rods 11 is beneficial to the balance and stability of the slider 10. The limiting grooves 12 in the receiving cavity 7, together with the limiting blocks 10 on the sides of the slider 10, can constrain the slider 10 and prevent it from completely detaching from the receiving cavity 7. The limiting grooves 12 and limiting blocks 13 on both sides can improve the stability of the restraint effect.
[0031] The working principle of this utility model is as follows: S1. Insert the heating component 4 into the embedded cavity 3, the toothed plate 6 enters the storage cavity 7, and drives the drive shaft 8 to rotate through the gear 9. Under the constraint of the guide rod 11, the drive shaft 8 pushes the slider 10 to move horizontally, so that the slider 10 moves out of the storage cavity 7. S2, the slider 10 moves the heating plate on it to the bottom of the cavity 2, and works with the heating plate inside the heating assembly 4 to heat the cavity 2 from multiple directions.
[0032] Compared with the prior art, the present invention has the following advantages: 1. The embedded heating element installation structure of this wood-plastic mold, through the setting of toothed plate 6, receiving cavity 7, drive shaft 8, gear 9, slider 10, guide rod 11, limiting groove 12 and limiting block 13, allows the heating component 4 to be inserted into the embedded cavity 3. The toothed plate 6 enters the receiving cavity 7, and the drive shaft 8 is driven to rotate by the gear 9. Under the constraint of the guide rod 11, the drive shaft 8 pushes the slider 10 to move horizontally, causing the slider 10 to move out of the receiving cavity 7. The slider 10 drives the heating plate on it to move to the bottom of the cavity 2, and together with the heating plate inside the heating component 4, the cavity 2 is heated in multiple directions, making the heating effect more uniform and excellent.
[0033] 2. The embedded heating element mounting structure of this wood-plastic mold features an inverted U-shaped heating component 4, allowing it to directly rely on its inner wall to provide a mounting platform for the heating plate, providing multi-faceted heating for the wood-plastic raw material. Ball bearings are installed at the bottom of the slider 10, reducing friction between the slider 10 and the inner wall of the receiving cavity 7, resulting in smoother movement of the slider 10. A limiting groove 12 is provided within the receiving cavity 7, which, in conjunction with the limiting block 10 on the side of the slider 10, constrains the slider 10, preventing it from completely detaching from the receiving cavity 7. The limiting groove 12 and limiting block 13 on both sides further enhance the stability of the restraint effect.
