[0036] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0037] Combination Figures 1-3 A plastic molding machine for quick mold changing includes a placement platform 1 and a fixed frame 2 fixedly connected to the top of the placement platform 1. The top of the placement platform 1 has a placement groove 11, and one side of the placement platform 1 has a sliding groove 111. A sealing plate 12 is slidably connected inside the sliding groove 111. A connecting frame 121 is fixedly connected to one side of the sealing plate 12, and a fixed rack 122 is fixedly connected to one side of the connecting frame 121. A first motor 123 is fixedly connected inside the placement platform 1. A gear 124 is fixedly connected to the output end of the first motor 123. The gear 124 meshes with the fixed rack 122. A mold body 13 is provided on the top of the sealing plate 12. A groove 125 is provided on the top of the sealing plate 12. A protrusion 131 is fixedly connected to the bottom of the mold body 13. A through hole 132 is provided on one side of the protrusion 131. A locking mechanism is provided inside the sealing plate 12.

[0038] The present invention will be further described below with reference to the embodiments.

[0039] Example 1:

[0040] Please see Figure 2 , Figure 3 , Figure 6 and Figure 7The card and mechanism are a second motor 14 fixedly connected inside the sealing plate 12. The output end of the second motor 14 is fixedly connected to a threaded rod 141. A sliding block 142 is threadedly connected to the outside of the threaded rod 141. The sliding block 142 is slidably connected inside the sealing plate 12 and matches the through hole 132. A water storage tank 17 is fixedly connected inside the placement platform 1. A recycling rack 18 is fixedly connected to the top of the water storage tank 17. A pump 171 is fixedly connected to one side of the water storage tank 17. A placement rack 172 is also fixedly connected inside the placement platform 1, and there are two sets of placement racks 172. The other end of the pump 171 is connected to the placement rack 172. A nozzle assembly 173 is fixedly connected to one side of the placement rack 172. The recycling rack 18 is equipped with... A filter screen frame 181 is provided, with a slot 182 on its top. A lever 183 is slidably connected to one side of the recycling rack 18, and a return spring 184 is fixedly connected to the top of the lever 183. The other end of the return spring 184 is fixedly connected to the inside of the recycling rack 18. A second locking block 185 is fixedly connected to the bottom of the lever 183, and the second locking block 185 matches the slot 182. When the plastic molding machine is used for a long time, the mold needs to be replaced. However, the existing mold connection method is relatively complicated, which is not conducive to quick replacement by the operator. When the mold body 13 needs to be replaced, the first motor 123 is started. The first motor 123 drives the gear 124 to rotate, which in turn causes the fixed rack 122 to move, thereby causing the connecting frame 12 to move. 1. Move to the outside of the placement slot 11. At this time, start the second motor 14. The second motor 14 drives the threaded rod 141 to rotate, thereby causing the sliding block 142 to disengage from the inside of the through hole 132. At this time, the mold body 13 can be removed from the top of the sealing plate 12. When it needs to be rotated, align the protrusion 131 at the bottom of the mold body 13 with the groove 125 and put it in. Then start the second motor 14 in reverse. Finally, start the first motor 123 in reverse so that the connecting bracket 121 returns to the inside of the slide 111. This realizes the function of quickly replacing the mold body 13 and promotes the workflow. Most existing plastic molding machines cool plastic molding by air cooling or natural cooling. This method has a relatively low cooling rate. The process is slow and inefficient. Therefore, pump 171 is activated to extract water from the water storage tank 17. When the water reaches the placement rack 172, the nozzle assembly 173 is activated to cool the plastic products inside the placement tank 11. The cooled water passes through the recycling rack 18 and is filtered by the filter screen frame 181 before returning to the water storage tank 17, allowing for water reuse. When the filter screen frame 181 needs cleaning, the lever 183 is moved, causing the second locking block 185 to move out of the slot 182, allowing for cleaning of the filter screen frame 181. This achieves faster cooling and molding of the plastic and also allows for the reuse of cooling water.

[0041] Example 2:

[0042] Please see Figure 4 The difference between this embodiment and embodiment 1 is that the locking mechanism is a third motor 15 fixedly connected inside the sealing plate 12. The output end of the third motor 15 is fixedly connected to a positive and negative threaded rod 151. The left and right sides of the positive and negative threaded rod 151 are threadedly connected to a first locking block 152. The first locking block 152 is slidably connected inside the sealing plate 12 and matches the through hole 132. When the third motor 15 is started, the third motor 15 drives the positive and negative threaded rod 151 to rotate. The positive and negative threaded rod 151 causes the first locking blocks 152 located on the left and right sides of the positive and negative threaded rod 151 to move. When the first locking block 152 moves out of the through hole 132, the mold body 13 can be removed from the sealing plate 12. When installation is required, the mold body 13 is placed on the sealing plate 12 and the third motor 15 is started in reverse.

[0043] Example 3:

[0044] Please see Figure 5 The difference between this embodiment and embodiments 1 and 2 is that the card and mechanism is an electric push rod 16 fixedly connected inside the sealing plate 12. The output end of the electric push rod 16 is fixedly connected to a connecting block 161, and the through hole 132 is arranged horizontally. The connecting block 161 matches the through hole 132. When the electric push rod 16 is activated, the electric push rod 16 drives the connecting block 161 to move, so that the connecting block 161 is dislodged from the inside of the through hole 132. At this time, the mold body 13 can be removed from the sealing plate 12. When installation is required, the mold body 13 is placed on the sealing plate 12 and the electric push rod 16 is activated in the reverse direction.
