[0002] Semi-automatic molding technology is widely used in chemical production, building materials, packaging materials and other fields. Semi-automatic foam molding machine is a kind of semi-automatic molding machine. The foam molding machine uses specific processes and equipment to mix the foaming agent with raw materials such as resin and inject them into the mold. After heating and expansion, foam products with porous structures are formed.

[0003] In the existing technology, the structure of a semi-automatic foam molding machine usually includes a machine body, a hydraulic device, a control system, and upper and lower templates. The foaming material and additives are mixed and put into the groove of the lower template.

[0024] Example 2

[0025] See also Figure 3On the basis of Example 1, in order to realize the alternation of the two lower templates 3 and the closed foaming of the upper template 2, two fixed grooves 10 are provided on the two end surfaces of the lower template 3, and the fixed groove 10 is a square groove. The extension platform 4 has a square plate-shaped structure. The surface of the extension platform 4 is provided with a slide groove 6, and the slide groove 6 is a "T"-shaped long groove. The two screw rods 8 are rotatably connected to the surface of the slide groove 6. One end of the screw rod 8 passes through the end of the extension platform 4 and is connected to the output end of the servo motor 5. There are two sliders 7 in each group, and the slider 7 has a "T"-shaped plate structure. The slider 7 is slidably connected to the surface of the slide groove 6. The surface of the slider 7 is provided with a rod groove 9, and the rod groove 9 is a circular groove.

[0026] A servo motor 5 is provided, and the servo motor 5 drives the screw rod 8 to rotate forward and reverse, so as to mate and close the first lower template 3 with the upper template 2. The second lower template 3 is exposed to the outside of the molding machine body 1, and the raw material can be poured into the groove of the second lower template 3. After the first lower template 3 is foamed and formed, the servo motor 5 rotates forward to mate and close the second lower template 3 with the upper template 2, demold the first lower template 3 and pour the granular raw material again, and then reverse and repeat the operation, so that the screw rod 8 drives the two lower templates 3 to alternately close and foam with the upper template 2.

[0027] Example 3

[0028] See also Figures 4 and 5 On the basis of Example 2, in order to realize the memory disassembly and cleaning of a single lower template 3, the vertical plate 13 has a square plate structure, and a socket 12 is opened on the surface of the vertical plate 13. The socket 12 is a square hole. The fixed block 11 is inserted into the surface of the socket 12, and one end of the fixed block 11 is inserted into the fixing groove 10. The end of the fixed block 11 away from the fixing groove 10 is fixedly connected to a baffle 17. The baffle 17 has a square plate structure, and limiting grooves 16 are opened at both ends of the surface of the baffle 17. The limiting groove 16 is a circular hole. The surface of the limiting groove 16 is inserted with a limiting rod 14. The limiting rod 14 has a "T"-shaped circular plate structure in cross section. One end of the limiting rod 14 is fixedly connected to the surface of the vertical plate 13. The outer circular plate diameter of the limiting rod 14 is larger than the aperture of the limiting groove 16. The surface of the limiting rod 14 is sleeved with a spring 15. One end of the spring 15 is fixedly connected to the surface of the vertical plate 13, and the other end of the spring 15 is fixedly connected to the surface of the baffle 17.

[0029] A vertical plate 13 is provided, and the vertical plate 13 is in contact with the surface of the lower template 3. A limit rod 14 is provided, and the limit rod 14 can limit the sliding range of the fixed block 11. The outer circular plate diameter of the limit rod 14 is larger than the aperture of the limit groove 16, so as to prevent the fixed block 11 from falling off from the socket 12 of the vertical plate 13 due to excessive stretching range. The limit rod 12 can also support and limit the spring 15, ensuring that the spring 15 can maintain its original shape and tightness when subjected to external force, and can provide better stability and load-bearing capacity. An inclined surface is provided at one end of the surface of the fixed block 11. After one end of the inclined surface is squeezed by the surface of the lower template 3, it moves toward the side of the socket 12, so that the lower template 3 is embedded between the four vertical plates 13. A spring 15 is provided. When the spring 15 is in its original state, the fixed block 11 is tightly clamped in the fixed groove 10 of the lower template 3 to prevent the fixed block 11 and the fixed groove 10 from loosening. When the baffle 17 is pulled, the spring 15 is in a stretched state, the fixed block 11 is separated from the fixed groove 10, and the lower template 3 loses its limit and can be disassembled and cleaned separately.

[0030] When in actual use, first move the lower template 3 downward from just above the four vertical plates 13, the bottom end of the lower template 3 contacts and squeezes the fixed block 11, and one end of the inclined surface of the fixed block 11 moves along the socket 12 to one end of the limit rod 14. At this time, the spring 15 changes from its original state to a stretched state. When the fixed groove 10 and the socket 12 are connected, the fixed block 11 loses its pressure, and the spring 15 returns to its original state from the stretched state, driving the fixed block 11 to rebound and be clamped in the fixed groove 10, thereby realizing the installation of the two lower templates 3. Then, pour the raw material onto the surface of the lower template 3, start the molding machine body 1 and the servo motor 5, the upper template 2 and one lower template 3 are closed for foaming, and the other lower template 3 can be fed at the same time. The servo motor 5 rotates forward and reversely to realize feeding and foaming at the same time, thereby improving production efficiency. When the lower template 3 needs to be disassembled, pull the baffle 17 by hand, and the baffle 17 drives the spring 15 to deform, thereby separating the fixed block 11 from the fixed groove 10. Finally, the lower template 3 can be taken out for separate cleaning or replacement.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
