[0003] However, existing molding machines typically use the interaction between upper and lower dies to extrude foam during operation. Since the foam is not fixed or restrained during this process, the foam's elasticity causes the center to be stressed during extrusion, and the four sides are not secured. This leads to the foam's sides warping, affecting the molding quality. Therefore, a new foam molding machine is proposed. Utility Model Content

Detailed Implementation
[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0023] Please see Figure 1-6 This utility model provides a technical solution: a foam molding machine, including a molding machine frame 1, a molding cylinder 16 fixedly connected to the top of the molding machine frame 1, the output end of the molding cylinder 16 passing through the interior of the molding machine frame 1 and slidably connected to the interior of the molding machine frame 1, an upper mold 2 fixedly connected to the output end of the molding cylinder 16, and a lower mold 4 fixedly connected to the inner wall of the molding machine frame 1. The lower mold 4 and the upper mold 2 cooperate with each other to press the foam into the shape of the product.
[0024] A placement frame 3 is provided between the upper mold 2 and the lower mold 4. A mounting plate 5 is fixedly connected to the inner wall of the placement frame 3 to provide space for the foam in the placement frame 3, preventing the foam from falling out of the placement frame 3. The size of the mounting plate 5 is larger than the size of the lower mold 4, so that the lower mold 4 can be retracted into the mounting plate 5, so that the mounting plate 5 can wrap the lower mold 4, and thus the foam can be laid on the lower mold 4, so that the upper mold 2 can smoothly press and shape the foam during the descent process.
[0025] The surface of the mounting plate 5 is threaded with threaded sleeves 12 arranged at equal intervals. The inner wall of the threaded sleeves 12 is slidably connected to a movable rod 11 to support the foam. At the same time, by rotating the threaded sleeves 12, the operator can adjust the height of the movable rod 11, so that the movable rod 11 can support foam of different thicknesses, which improves the applicability of the device and is worth promoting. One end of the movable rod 11 is fixedly connected to a third spring 15. The end of the third spring 15 away from the movable rod 11 is fixedly connected to the inner wall of the threaded sleeves 12 to reset the movable rod 11.
[0026] Four sliding rods 8 are fixedly connected to the bottom of the placement frame 3. The surface of the sliding rods 8 is slidably connected to the inside of the molding machine frame 1 to connect the placement frame 3 to the molding machine frame 1. A top rod 10 is slidably connected inside the sliding rods 8. The surface of the top rod 10 is also slidably connected to the inside of the placement frame 3. A first spring 9 is movably sleeved on the surface of the top rod 10. One end of the first spring 9 is fixedly connected to the surface of the sliding rod 8. The end of the first spring 9 away from the sliding rod 8 is in contact with the inside of the molding machine frame 1, so that it can be used in conjunction with the sliding rods 8 to support the placement frame 3.
[0027] The inner wall of the placement frame 3 is provided with sliding grooves 7 on all four sides. The inner wall of the sliding groove 7 is slidably connected to a pressure plate 6 with one side being inclined. The pressure plate 6 has an extrusion groove 14 with an inclined inner wall on one side. The extrusion groove 14 corresponds to the top rod 10. A second spring 13 is fixedly connected to the surface of the pressure plate 6. The end of the second spring 13 away from the pressure plate 6 is fixedly connected to the inner wall of the sliding groove 7 to reset the pressure plate 6.
[0028] The slide bar 8 has a slot 18 on its surface, and the molded machine frame 1 has an L-shaped locking rod 17 slidably connected to it. The locking rod 17 is in contact with the surface of the slide bar 8, and the locking rod 17 and the slot 18 are compatible with each other. At the same time, the L-shaped locking rod 17 is convenient for the operator to operate. A third spring 15 is also fixedly connected between the locking rod 17 and the molded machine frame 1 to reset the locking rod 17. When the locking rod 17 is not inserted into the slot 18, the slide bar 8 blocks the movement path of the locking rod 17, so the third spring 15 on the locking rod 17 is in a compressed state.
[0029] Specifically, during use, the operator first adjusts the height of the movable rod 11 by rotating the threaded sleeve 12 according to the thickness of the foam, ensuring that the upper side of the foam does not exceed the pressure plate 6 after being placed on the movable rod 11. Then, the foam is placed in the placement frame 3 for initial restraint. Next, the molding cylinder 16 is activated to drive the upper mold 2 downwards, inserting it into the placement frame 3 to compress the foam. Since the placement frame 3 has movable space, it descends synchronously as the upper mold 2 compresses the foam, causing the slide rod 8 to slide down within the molding machine frame 1 and compress the first spring 9. Simultaneously, the push rod 10 retracts into the placement frame 3, thus allowing the push rod 10 to... The pressure plate 6 is pressed against the inclined surface of the inner wall of the extrusion groove 14, thereby pushing the pressure plate 6 to slide from the slide groove 7 and stretching the second spring 13. This causes the inclined surface of the pressure plate 6 to press against the surface of the foam, which in turn causes the foam to press against the movable rod 11, allowing the foam to contact the threaded sleeve 12. This also compresses the third spring 15, squeezing the foam between the pressure plate 6 and the threaded sleeve 12. Then, as the upper mold 2 presses against the foam, the foam comes into contact with the lower mold 4. At this point, the pressure plate 6 and the threaded sleeve 12 work together to press and fix the foam, thus preventing the foam from moving during the pressing process and affecting the foam molding quality. This improves the effectiveness of the device and is worth promoting.
[0030] As the slide bar 8 descends, the slot 18 on the slide bar 8 gradually aligns with the locking rod 17. At this time, under the elastic force of the third spring 15 on the locking rod 17, the locking rod 17 inserts into the slot 18, thereby fixing the position of the placement frame 3, preventing the placement frame 3 from automatically resetting, and ensuring the smooth operation of the device.
[0031] After the foam is formed, the upper mold 2 rises under the action of the molding cylinder 16, thereby separating the upper mold 2 from the placement frame 3. At this time, because the four sides of the foam are squeezed and fixed by the threaded sleeve 12 and the pressure plate 6, the upper mold 2 does not drive the foam to rise synchronously during the rising process, thus completing the demolding between the foam and the upper mold 2. When removing the foam, the locking rod 17 is moved, causing the locking rod 17 to separate from the locking groove 18, thereby removing the placement frame 3 from the fixation. At this time, under the elastic force of the first spring 9, the third spring 15 and the second spring 13, the placement frame 3 is removed. Frame 3 returns to its original state. During the device reset process, the foam is squeezed and fixed by the threaded sleeve 12 and the pressure plate 6 on all four sides. As the upper mold 2 rises, the foam can be directly demolded from the lower mold 4. At this time, the operator can directly take out the molded foam. Thus, during the use of the device, the foam can be separated from the upper mold 2 and the lower mold 4 in sequence, so that the foam will not cover any mold. This makes it easier for the operator to take out the molded foam and improves the convenience of the device.
[0032] Working principle: In use, the operator first adjusts the height of the movable rod 11 by rotating the threaded sleeve 12 according to the thickness of the foam, so that the upper side of the foam does not exceed the pressure plate 6 after being placed on the movable rod 11. Then, the foam can be placed in the placement frame 3 to initially restrict the foam. Then, the molding cylinder 16 is activated to drive the upper mold 2 to descend, so that the upper mold 2 is inserted into the placement frame 3 to compress the foam. Since the placement frame 3 has movable space at this time, as the upper mold 2 compresses the foam, the placement frame 3 descends synchronously, which causes the slide rod 8 to slide down in the molding machine frame 1 and compress the first spring 9. At the same time, the top rod 10 retracts into the placement frame. In step 3, the push rod 10 presses the inclined surface of the inner wall of the extrusion groove 14, thereby pushing the pressure plate 6 to slide from the slide groove 7 and stretching the second spring 13. This causes the inclined surface of the pressure plate 6 to press the foam surface, which in turn causes the foam to press the movable rod 11, allowing the foam to contact the threaded sleeve 12 and compress the third spring 15, thus squeezing the foam between the pressure plate 6 and the threaded sleeve 12. Then, as the upper mold 2 presses the foam, the foam comes into contact with the lower mold 4. At this time, because the pressure plate 6 and the threaded sleeve 12 cooperate to squeeze and fix the foam, the foam is prevented from moving during the pressing process, which would affect the foam molding quality.
[0033] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
