Description

Technical Field

[0001] The invention relates to the technical field of production of extruded foam composite boards, in particular to a forming die for production of extruded foam composite boards. Background Art

[0002] Extruded foam composite board is a new type of thermal insulation material, which is composed of extruded polystyrene foam board and other materials (such as fiber cement board, aluminum board, etc.). It combines the excellent thermal insulation performance and low water absorption of extruded polystyrene foam board with the high strength, fire resistance, moisture resistance and other characteristics of composite materials. It is widely used in the fields of building exterior wall insulation, roof waterproofing and insulation. Extruded foam composite board requires the use of forming molds for shaping and manufacturing during the production process. Through a specific structural design, the extruded polystyrene foam material and the composite layer material are pressed and bonded in the mold to form a predetermined shape and size. The quality and precision of the mold directly affect the quality and production efficiency of the composite board. Different molds can produce extruded foam composite boards of different specifications and different surface textures.

[0003] During the production of extruded foam composite panels: 1. Traditional mold assembly often requires operators to manually perform complex fastening operations, such as using bolts and other connectors to secure the mold top and base. This is not only time-consuming but also requires high technical skills from the operator. Improper operation can easily lead to loose joints, leakage during the injection molding process, and other problems, affecting product quality. Moreover, frequent operations such as removing and installing bolts can cause wear on the threaded holes of the mold, reducing the mold's service life. 2. Extruded foam composite panels generate a large amount of heat during the injection molding process. If heat is not dissipated in a timely and effective manner, the product's finalization time will be extended, reducing production efficiency. Summary of the Invention

[0018] Compared with the prior art, the present invention provides a forming mold for producing extruded foam composite panels, which has the following beneficial effects:

[0019] 1. The forming mold for producing extruded foam composite panels has a self-locking mechanism. The operator only needs to snap the mold top cover onto the top of the mold base. The conical snap ring will then move downward to automatically squeeze the slides on both sides. After the slides are retracted, they are snapped onto the outer ring of the protruding rod under the action of a compression spring. The mold top cover is positioned by the conical snap ring. The operator does not need to fix the mold base and the mold top cover separately. Once the mold top cover is placed on top of the mold base, it will automatically lock, making it easy for the operator to splice and fix the mold base and the mold top cover. The operation is simple and convenient for the operator to use.

[0020] The operator only needs to press the pressing block downward to drive the inverted conical collar downward, so that the inverted conical collar squeezes the self-locking blocks on both sides downward again to make them retract. Then the inverted conical collar cooperates with the conical clamping ring, so that the self-locking blocks can no longer be clamped on the top of the conical clamping ring. The operator only needs to press the pressing blocks at the four corners to release the lock between the mold base and the mold top cover, which is convenient for the operator to disassemble the mold base and the mold top cover. The operation is simple and convenient for the operator to use.

[0021] 2. The forming mold for the production of extruded foam composite boards has a heat dissipation mechanism, and a card plate is arranged at the top of the mold base, located at the top of the mold base, just below the mold groove, to conduct heat to the extruded foam composite board that has been injection-molded in the mold base and the mold top cover, so that the heat of the composite board itself is conducted to the water body in the heat conduction water tank through the card plate and the heat conduction plate. The water body in the heat conduction water tank is reciprocated through the water body and the liquid pipe arranged inside the water tank, so that the exhaust fan draws the air inside the mold base to exchange the heat in the water body with the air through the heat dissipation plate, and the reciprocating movement of the water body completes the cooling of the card plate, thereby accelerating the shaping speed of the extruded foam composite board, increasing the time for processing the extruded foam composite board when the mold is used, and improving the working efficiency of the mold during use.

[0022] 3. The forming mold for the production of extruded foam composite panels has an air filtering mechanism, and the card frame is set on the rear side of the mold base. The external air entering the mold base is filtered by the internal air filter element, so that dust and water vapor in the external air cannot enter the mold base and contact the surface of the heat sink. This ensures that the surface of the heat sink can remain clean after the mold is used for a long time, ensures the heat dissipation efficiency of the heat sink, and improves the cooling effect of the composite board during the use of the mold. The operator only needs to push the movable lever upward to drive the positioning card block upward to release the positioning of the card frame, which is convenient for the operator to open and close the card frame, and convenient for the operator to clean and maintain the internal structure of the mold base, thereby improving the overall service life of the device.

[0047] Example 2

[0048] See Figure 1 、 Figure 3 、 Figure 4 、 Figure 9 and Figure 10On the basis of Example 1, it is further obtained that the heat dissipation mechanism 2 includes a heat conducting component 21 and a heat dissipation component 22 , the heat conducting component 21 is arranged in the mold base 4 , and the heat dissipation component 22 is arranged on the outer ring of the heat conducting component 21 .

[0051] Example 3

[0052] See Figure 2 、 Figure 4 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 、 Figure 14 , and on the basis of Example 1 and Example 2, it is further obtained that the air filtering mechanism 3 includes a filter plate assembly 31, a filter element assembly 32 and a positioning assembly 33, the filter plate assembly 31 is arranged on the rear side of the mold base 4, the filter element assembly 32 is arranged in the filter plate assembly 31, and the positioning assembly 33 is arranged on the rear side of the filter plate assembly 31.

[0053] The filter plate assembly 31 includes a card frame 3101, which is clamped in the rear side of the mold base 4, and a rotating rack 3102 is fixedly connected to the bottom of the rear side of the card frame 3101. The bottom of the rotating rack 3102 is rotatably connected to the bracket 3103, and the bracket 3103 is fixedly connected to the rear side of the mold base 4. The top of the rear side of the card frame 3101 is fixedly connected to the handle 3104. The filter element assembly 32 includes an air filter element 3201, and the air filter element 3201 is arranged in the card frame 3101. A card strip 3202 is arranged above the air filter element 3201, and the card strip 3202 is clamped in the left and right sides of the card frame 3101. The right side of the card strip 3202 is fixedly connected to the limiting plate 3203, and the limiting plate 3203 is clamped in the right side of the card frame 3101. A positioning block 3204 is arranged above the card strip 3202, and the positioning block 3204 is slidably connected to the bottom of the mold. On the rear side of the seat 4, the positioning block 3204 is clamped in the top of the clamping strip 3202, and the rear side of the positioning block 3204 is fixedly connected to the moving lever 3205, and the moving lever 3205 is slidably connected to the rear side of the mold base 4. The positioning assembly 33 includes a fixed cylinder 3301, which is fixedly connected to the top of the rear side of the clamping frame 3101, and the inner ring of the fixed cylinder 3301 is slidably connected to the slide 3302, and the rear side of the slide 3302 is fixedly connected to the compression spring 2 3303, and the front side of the slide 3302 is fixedly connected to the clamping rod 3304, and the clamping rod 3304 passes forward through the clamping frame 3101 and is clamped in the clamping strip 3202, and the rear side of the slide 3302 is fixedly connected to the telescopic slide 3305, and the telescopic slide 3305 is slidably connected to the rear side of the fixed cylinder 3301, and the rear side of the telescopic slide 3305 is fixedly connected to the dial plate 3306.

[0054] Furthermore, the operator only needs to pull the dial plate 3306 backward to unlock the card strip 3202, so that the operator can disassemble the card strip 3202 and then disassemble and replace the air filter element 3201, so that the air filter element 3201 will not be affected by the air filtering effect due to long-term use and cannot be replaced, ensuring that the mold can maintain stable air filtering and heat dissipation effects during long-term use.

[0055] During actual operation, when this device is used, when the mold base 4 and the mold top cover 5 need to be installed, first place the mold top cover 5 on the mold base 4, so that the bayonet 1101 and the conical clamping ring 1103 are aligned with the inner groove of the top of the mold base 4, and then move the mold top cover 5 downward, so that the bayonet 1101 and the conical clamping ring 1103 are clamped in the top of the mold base 4, and the top of the mold base 4 and the bottom of the mold top cover 5 are in a fitting position. When the conical clamping ring 1103 moves downward and is clamped in the top of the mold base 4, the conical clamping ring 1103 is clamped in the top of the mold base 4. The clamping ring 1103 first releases the self-locking block 1202 to squeeze the self-locking block 1202, so that the self-locking block 1202 is forced to move back into the mold base 4, and then the conical clamping ring 1103 continues to move downward to below the self-locking block 1202 until the conical clamping ring 1103 is completely moved below the self-locking block 1202. At this time, the slide 1201 drives the self-locking block 1202 to move inward under the action of the compression spring 1203 and is engaged with the conical clamping ring 1103. At this time, the mold top cover 5 is locked;

[0056] After that, the molding of the composite board can be completed by injection molding the inside of the mold, and then the exhaust fan 2203 is started. The exhaust fan 2203 starts to draw the air inside the mold base 4 forward. At this time, negative pressure is formed in the mold base 4, and the external air is drawn into the mold base 4 through the card frame 3101. The water in the heat conduction water tank 2103 and the liquid pipe 2104 is circulated by the water pump provided in the heat conduction water tank 2103, so that the water in the heat conduction water tank 2103 that contacts the heat conduction plate 2102 and heats up flows downward into the liquid pipe 2104, and the water in the liquid pipe 2104 exchanges heat with the air through the heat dissipation plate 2201. Through the above two heat exchange steps, the card plate 2101 and the heat conduction plate 2102 are cooled, so that the cooling speed of the composite board inside the mold is accelerated during the molding process, and the molding is faster.

[0057] After the composite plate is formed, the pressing blocks 1402 at the four corners are pressed downward, and the pressing blocks 1402 move downward and drive the pressing rod 1404 to move downward through the slide cylinder 1401, and the pressing rod 1404 moves downward to push the slider 1303 to move downward, and the slider 1303 moves downward and drives the inverted conical ring 1304 to move downward through the moving slide rod 1302 and the slip ring 1301. The downward movement of the inverted conical ring 1304 is the same as the conical clamping ring 1103, and the self-locking block 1202 is contacted and squeezed, so that the self-locking block 1202 retracts into the mold base 4 to release the position of the conical clamping ring 1103, and at this time the inverted conical ring 1304 is squeezed inward by the self-locking blocks 1202 on both sides and cannot return to the position by itself. The mold top cover 5 is then moved upwards, and the mold top cover 5 drives the conical clamping ring 1103 upwards. At this time, the splicing between the conical clamping ring 1103 and the inverted conical collar 1304 will not be directly released until the conical clamping ring 1103 moves above the self-locking block 1202. The self-locking blocks 1202 on both sides release the contact with the inverted conical collar 1304, and the inverted conical collar 1304 can be reset upwards under the action of the reset spring 1305. At this time, the disassembly of the mold base 4 is completed, and the formed composite plate can be disassembled. Then, the above process is repeated to prepare the composite plate.

[0058] When the filter element 3201 needs to be removed, first push the moving lever 3205 upward, and the moving lever 3205 moves upward to drive the positioning block 3204 to move upward. The positioning block 3204 moves upward to release the connection with the filter element 3201, thereby releasing the positioning of the card frame 3101. Then, the handle 3104 can be held to drive the card frame 3101 to flip backward. After the card frame 3101 flips backward, move the card strip 3202 to the right, and the card strip 3202 moves to the right to disengage from the card frame 3101, thereby releasing the positioning of the filter element 3201. At this time, the filter element 3201 can be moved upward to complete the removal of the filter element 3201, and then the new filter element 3201 can be placed in the card frame 3101. Then, reverse the above steps and fix the card frame 3101 in the rear side of the mold base 4. At this time, the replacement of the filter element 3201 is completed.
