[0020] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0021] Example 1: A refrigerator guide rail forming mold, see Figures 1 to 4, including a lower mold 2 and an upper mold 3, the bottom of the lower mold 2 is provided with a base 1, the top of the lower mold 2 is provided with an upper mold 3, the lower mold 2 and the base 1 are connected for sliding, the lower mold 2 is symmetrically distributed, the side of the base 1 is fixedly connected to the bracket plate 14, due to the bracket plate 14 provided, and an internal threaded sleeve 15 is installed on the bracket plate 14 to connect the screw rod 12, so that the internal threaded sleeve 15 and the screw rod 12 can be provided with a higher stability by the bracket plate 14 when in use, and will not easily shake. The internal threaded sleeve 15 is embedded in the interior of the bracket plate 14, and the internal thread of the internal threaded sleeve 15 is connected to the screw rod 12. A cross handle 13 is provided at one end of the screw rod 12. The other end is connected to the lower mold 2 through the turntable 11, and a side-pull lower mold 2 is provided on the base 1, and the two halves of the lower mold 2 can be combined and separated with each other. In this way, during the subsequent demoulding, it is only necessary to rotate the screw rods 12 on both sides so that the screw rods 12 move outward from the inside of the internal threaded sleeve 15 to drive the lower mold 2 to move outward respectively. In this way, the internal guide rail workpiece can be directly separated from the lower mold 2, thereby achieving rapid demoulding, and no external force will apply pressure to the guide rail workpiece during the entire demoulding process, so that the surface of the guide rail workpiece will not be damaged due to pressure, and the internal guide rail workpiece can be better protected during demoulding.

[0022] For details, see Figure 1 and Figure 2 The side of the lower mold 2 is fixedly connected to the sleeve frame 7, the interior of the sleeve frame 7 is inserted into the limit plate 8, the top of the base 1 is provided with a limit groove 9, the bottom of the limit plate 8 is inserted into the interior of the limit groove 9, and the top of the limit plate 8 is fixedly connected to the baffle 10. By installing the limit plate 8 on the side of the lower mold 2 and combining it with the limit groove 9 on the base 1, when the lower mold 2 is merged, the limit plate 8 can be lowered and embedded in the interior of the limit groove 9, so that the position of the lower mold 2 can be locked, thereby avoiding the displacement of the lower mold 2 when the screw rod 12 is accidentally touched.

[0023] For further information, see Figure 1 A mold cavity 6 is opened inside the lower mold 2, a guide column 5 is provided at the bottom of the upper mold 3, a guide sleeve 4 is installed on the side of the base 1, and the guide column 5 is movably connected to the internal part of the guide sleeve 4. By providing a guide column 5 between the upper mold 3 and the base 1, the upper mold 3 can be conveniently positioned and installed when the upper mold 3 is installed. The guide column 5 is aligned with the guide sleeve 4 and embedded into it to complete the mold closing work, which is more convenient to operate.

[0024] It is worth noting that, see Figure 3The inside of the base 1 is provided with a through hole, the side surface of the base 1 is provided with a strip-shaped groove 21, the inside of the base 1 is provided with a silica gel pull-out plate 18, the side surface of the silica gel pull-out plate 18 is fixedly connected with a sliding rod 20, and the sliding rod 20 is movably connected in the inside of the strip-shaped groove 21. By arranging the silica gel pull-out plate 18 which can move forward and backward in the inside of the base 1, and by arranging an open space in the inside of the base 1, when the guide rail workpiece is formed, it can pass through the base 1 and fall on the silica gel pull-out plate 18. Since the pull-out plate is made of hard silica gel material, it has a certain hardness and can avoid the guide rail workpiece from being knocked and damaged.

[0025] It is worth noting that, referring to Figure 2 The lower die 2 is provided with a sliding block piece 16, the side surface of the base 1 is provided with a sliding groove 17, and the sliding block piece 16 is movably embedded in the inside of the sliding groove 17. By arranging the sliding block piece 16 to slide-connect between the lower die 2 and the base 1, the movement of the lower die 2 to the two sides is more smooth, and the jamming condition is avoided.

[0026] It is worth noting that, referring to Figure 4 The two side surfaces of the silica gel pull-out plate 18 are provided with a handle 19, and the silica gel pull-out plate 18 is located below the mold cavity 6. Since the position of the silica gel pull-out plate 18 is just below the mold cavity 6, when the guide rail workpiece is formed, it can fall on the silica gel pull-out plate 18 at the moment of demolding, so as to facilitate the work personnel to pull it out, and the operation is more flexible and convenient.

[0027] In use of the refrigerator rail forming die, first, the upper die 3 and the lower die 2 need to be closed, and at the same time, since the guide sleeve 4 is installed on the side of the base 1, the guide column 5 at the bottom of the upper die 3 can be conveniently positioned and installed, the guide column 5 is aligned with the guide sleeve 4 and embedded into the guide sleeve 4, and the closing work is completed, and the operation is relatively convenient, then the die is installed on the corresponding forming device, then the raw material is injected into the inside of the mold cavity 6, after waiting for a fixed time, the rail workpiece can be formed in the inside of the mold cavity 6, and then the rail workpiece can be demolded, and since the side-pulling type lower die 2 is arranged on the base 1, and the two half lower dies 2 can be combined and separated from each other, when demolding, only the two side screw rods 12 need to be rotated, so that the screw rods 12 move outward from the inside of the internal thread sleeve 15, to drive the lower die 2 to move outward, so that the rail workpiece in the inside can be directly separated from the lower die 2, so that rapid demolding can be realized, and the entire demolding process does not apply pressure to the rail workpiece, so that the surface of the rail workpiece is not damaged due to pressure, and the rail workpiece in the inside can be better protected during demolding, and at the moment when the demolding is completed, since the upper and lower through spaces are arranged in the inside of the base 1, and the silicon rubber pull-out plate 18 that can slide forward and backward is arranged in the inside of the space, at this moment, the rail workpiece falls on the silicon rubber pull-out plate 18 through the base 1, and since the pull-out plate is made of hard silicon rubber material, has a certain hardness, and can avoid the rail workpiece from being damaged due to falling, finally, the staff pulls the handle 19 on the side of the silicon rubber pull-out plate 18 to pull the silicon rubber pull-out plate 18 out of the inside of the base 1, so that the rail workpiece can be taken out, so that the rail workpiece can be quickly taken out, and the entire operation process is simple and convenient, and the operation is relatively flexible.
