Description

Technical Field

[0001] The utility model relates to the technical field of hot pressing dies, and particularly relates to a hot pressing die for reducing wear. Background Technique

[0002] A hot pressing die is a die used to form a slab after paving into a fiber board with specific mechanical strength and water resistance through heating and pressing. Whether it is wet production of hard boards or semi-hard boards, or dry production of hard boards or medium density fiberboards, they all need to go through a hot pressing process to become boards. The hot pressing die plays a crucial role in this process, ensuring the quality and performance of the boards. The design and use of hot pressing dies involve multiple aspects, including the selection of die materials, the control of heating and pressing, etc., to ensure the quality and durability of the final product.

[0003] Conventional hot pressing dies are repeatedly subjected to high temperatures during use, causing mechanical erosion and loss on the surface and inside of the die due to overheating. Conventional heat dissipation cannot conduct heat to the die during processing in real time, making it impossible to effectively ensure that the die can dissipate heat effectively during die casting, resulting in a certain degree of wear on the surface of the die.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a hot pressing die for reducing wear is proposed. Content of the Utility Model

Fixed wedges are installed on both left and right sides of the heat dissipation seat assembly, and fixing pins are vertically inserted at the four diagonal corners of the heat dissipation seat assembly. The heat dissipation seat assembly includes a first heat conduction seat, a second heat conduction seat, a third heat conduction seat, and docking piles. The bottom of the first heat conduction seat is connected to the second heat conduction seat, the bottom of the second heat conduction seat is connected to the third heat conduction seat, and docking piles are provided at the four diagonal corners of the top surfaces of the second heat conduction seat and the third heat conduction seat.

[0007] Furthermore, the die assembly includes a die body, a heat conduction plate, and fixing insertion piles. A heat conduction plate is installed at the center of the bottom of the die body, and fixing insertion piles are installed around the heat conduction plate.

[0008] Furthermore, the fixed insertion piles are fixedly installed at the four diagonal corners of the bottom surface of the mold body, and the mold body is fixedly connected to the heat conduction plate.

Moreover, a groove structure that matches the top surface structure of the first heat conduction tube is provided on the bottom surface of the first heat conduction base.

Moreover, groove structures that match the lower surface of the first heat conduction tube and the upper surface of the second heat conduction tube are respectively provided on the upper and lower surfaces of the second heat conduction base. In addition, the structures of the second heat conduction tube and the first heat conduction tube are the same.

[0011] Furthermore, a groove structure that matches the lower surface structure of the second heat conduction tube is provided on the top surface of the third heat conduction base, and the fixing pins vertically penetrate through the four diagonal corners of the third heat conduction base, the second heat conduction base, and the first heat conduction base from bottom to top in sequence.

[0015] 1. In this utility model, the heat-conducting plate and the fixed insertion piles on the bottom surface of the mold body are vertically inserted into the top surface of the first heat-conducting seat. Then, the first heat-conducting pipe between the first heat-conducting seat and the second heat-conducting seat, and the second heat-conducting pipe between the second heat-conducting seat and the third heat-conducting seat are respectively connected to the equipment that supplies the external coolant in a circulating manner. At the same time, by utilizing the characteristics of the heat-conducting plate and the structural materials of the heat-dissipating seat assembly itself, the heat inside the mold body can be quickly absorbed and conducted. And as the coolant flows through the inside of the first heat-conducting pipe and the second heat-conducting pipe, the heat absorbed inside the entire heat-dissipating seat assembly can be quickly taken away.

The structure between the second heat conduction tube 4 and the first heat conduction tube 3 is the same. A groove structure that matches the lower surface structure of the second heat conduction tube 4 is provided on the top surface of the third heat conduction seat 203. The fixing pins 6 vertically penetrate through the four diagonal corners of the third heat conduction seat 203, the second heat conduction seat 202, and the first heat conduction seat 201 from bottom to top in sequence. By vertically inserting the heat conduction plate 102 and the fixed insertion pile 103 on the bottom surface of the die body 101 into the top surface of the first heat conduction seat 201, then connecting the first heat conduction tube 3 between the first heat conduction seat 201 and the second heat conduction seat 202, and the second heat conduction tube 4 between the second heat conduction seat 202 and the third heat conduction seat 203, respectively, to the equipment for circulating and supplying external coolant, and at the same time, using the characteristics of the heat conduction plate 102 and the structural materials of the heat dissipation seat assembly 2 itself, the heat inside the die body 101 can be quickly absorbed and conducted, and as the coolant flows through the inside of the first heat conduction tube 3 and the second heat conduction tube 4, the heat absorbed inside the entire heat dissipation seat assembly 2 can be quickly taken away.

[0024] As Figures 1 to 4As shown in the figure, the mold assembly 1 includes a mold body 101, a heat conducting plate 102 and fixed insertion piles 103. A heat conducting plate 102 is installed at the center of the bottom of the mold body 101, and fixed insertion piles 103 are installed around the heat conducting plate 102. The fixed insertion piles 103 are fixedly installed at the four diagonal corners of the bottom surface of the mold body 101, and the mold body 101 and the heat conducting plate 102 are fixedly connected. The fixed wedge 5 includes a wedge body 501, positioning piles 502 and fixing bolts 503. Three groups of positioning piles 502 are arranged and connected on one side of the wedge body 501, and three groups of fixing bolts 503 horizontally penetrate through the inside of the wedge body 501 and the positioning piles 502. The wedge body 501 is connected to the first heat conducting seat 201, the second heat conducting seat 202 and the third heat conducting seat 203 respectively by an embedded structure, and the positioning piles 502 are horizontally inserted into the sides of the first heat conducting seat 201, the second heat conducting seat 202 and the third heat conducting seat 203 respectively. Moreover, the fixing bolts 503 are threadedly connected to the first heat conducting seat 201, the second heat conducting seat 202 and the third heat conducting seat 203 respectively. During use, only need to vertically stack the first heat conducting seat 201, the second heat conducting seat 202 and the third heat conducting seat 203 in sequence by using the docking piles 204, then vertically insert four groups of fixing pins 6 from bottom to top into the four diagonal corners of the heat dissipation seat assembly 2, then insert the wedge bodies 501 connected with the three groups of positioning piles 502 into the sides of the heat dissipation seat assembly 2 respectively, and finally only need to use three groups of fixing bolts 503 to connect and fix the wedge body 501 and the heat dissipation seat assembly 2.

[0025] In summary, as Figures 1 to 4 shown, for the hot pressing mold with reduced wear, during use, first vertically insert four groups of fixing pins 6 from bottom to top into the four diagonal corners of the third heat conducting seat 203 respectively, then embed the second heat conducting tube 4 into the top surface of the third heat conducting seat 203, then use the docking piles 204 at the top surfaces of the four diagonal corners of the third heat conducting seat 203 and the fixing pins 6 respectively to insert and dock the bottom of the second heat conducting seat 202 with the top of the third heat conducting seat 203. Subsequently, embed the first heat conducting tube 3 into the top surface of the second heat conducting seat 202, and then insert and dock the bottom of the first heat conducting seat 201 vertically by using the docking piles 204 at the top surfaces of the four diagonal corners of the second heat conducting seat 202 and the fixing pins 6, so as to complete the combination of the entire heat dissipation seat assembly 2;

[0026] Then connect the first heat conducting tube 3 and the second heat conducting tube 4 to an external coolant circulation supply device to ensure that the coolant can circulate uniformly through the inside of the first heat conducting tube 3 and the second heat conducting tube 4. Then horizontally insert the wedge body 501 with positioning piles 502 connected to its side into the side of the heat dissipation seat assembly 2, and then sequentially screw the fixing bolts 503 into the inside of the wedge body 501, the positioning piles 502 and the heat dissipation seat assembly 2, so as to connect and fix the heat dissipation seat assembly 2 and the fixed wedge 5;

[0027] Finally, only the heat conduction plate 102 and the fixed insertion pile 103 at the bottom of the mold body 101 need to be vertically inserted into the top of the first heat conduction seat 201 to complete the combined docking of the mold assembly 1 and the heat dissipation seat assembly 2. In this way, during the use of the mold assembly 1, the heat inside the mold assembly 1 is adsorbed and conducted by the heat dissipation seat assembly 2, the first heat conduction pipe 3, and the second heat conduction pipe 4, so as to achieve heat dissipation protection, thereby reducing the mechanical erosion and loss caused by overheating on the surface and inside of the mold assembly 1.
