Description

Technical Field

[0001] The utility model belongs to the technical field of children's bathtubs and relates to an injection mold for children's bathtubs. Background Technique

[0002] Children's bathtubs are tools that are frequently used in families at present. Through children's bathtubs, it is convenient to bathe infants and young children. At present, most children's bathtubs are made by plastic injection molding. In order to further reduce the space occupied by children's bathtubs, the current children's bathtubs are generally foldable bathtubs. When producing and processing foldable bathtubs, multiple molds are generally required to inject different parts of the children's bathtub separately. For example, after separately injecting the bottom plastic part and the top plastic part, soft silicone is then injected between the bottom plastic part and the top plastic part for connection.

[0003] Traditional injection molds for children's bathtubs cannot simultaneously inject multiple plastic parts of children's bathtubs. Therefore, multiple individual molds need to be opened for separate processing, which affects the injection efficiency of children's bathtubs. For this reason, we have designed an injection mold for children's bathtubs to solve the above technical problems. Summary of the Invention

[0020] Specifically, through the cooperation of the semi-circular blocks 6 provided on both sides of the inner wall of the die core 5 and the rectangular blocks 14 provided on both sides of the shaping module 13, when injecting plastic for the children's bathtub, the internal mold cavity can be divided into a lower mold cavity and an upper mold cavity, realizing synchronous injection molding of the bottom and top of the children, making the middle hollow, facilitating the injection of silicone rubber, replacing the problem that the traditional children's bathtub needs to be injection molded in multiple parts separately, and improving the injection molding efficiency of the children's bathtub.

[0021] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, for a plastic injection mold for a children's bathtub of the present invention, clamping grooves 21 are opened on both outer sides of the die core 5. Installation grooves are opened on both sides of the inner wall of the groove 4. Clamping blocks 20 are slidably connected inside the two installation grooves. The clamping blocks 20 are snap-fitted with the clamping grooves 21. Threaded push rods 8 are threadedly connected to both sides of the lower die base 2. The ends of the threaded push rods 8 extend into the installation grooves and are rotatably connected to the centers of the corresponding clamping blocks 20.

[0022] Specifically, by pushing the clamping blocks 20 to be snap-fitted with the clamping grooves 21 by the threaded push rods 8, it is convenient for the assembly and disassembly of the die core 5.

[0023] Four positioning guide posts 3 are fixedly provided at the four corners at the top end of the lower die base 2. Positioning guide holes adapted to the positioning guide posts 3 are provided at the four corners at the bottom end of the upper die base 10, and the positioning guide posts 3 are nested and connected with the positioning guide holes.

[0024] Specifically, through the cooperation of the positioning guide posts 3 and the positioning guide holes, the die closing accuracy of the upper die base 10 and the lower die base 2 is improved.

[0026] Specifically, through the cooperation of the locking modules 12 and the locking grooves, the stability of die closing of the upper die base 10 and the lower die base 2 is improved.

[0027] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, in an injection mold for a children's bathtub of the present utility model, a pouring port 11 is fixedly provided at the top end of the upper die base 10. Material discharge holes 15 are provided at the top and bottom of the shaping module 13, and the pouring port 11 is communicated with the material discharge holes 15.

[0028] Specifically, through the material discharge holes 15 provided at the top and bottom, it is convenient to realize synchronous injection molding of the top and bottom.

[0029] A rectangular cavity 17 is formed inside the shaping module 13. Connecting rods 18 are inserted through both sides of the inner wall of the rectangular cavity 17.

Two symmetrically arranged second electric push rods 19 are fixedly installed in the middle of the rectangular cavity 17, and the telescopic ends of the second electric push rods 19 are fixedly connected to the other ends of the corresponding connecting rods 18.

[0030] Specifically, by the second electric push rod 19 pushing the connecting rod 18 to move, the telescopic movement of the rectangular block 14 is driven by the movement of the connecting rod 18. Through the telescopic movement of the rectangular block 14, the rectangular block 14 is pushed out during injection molding and retracted during demolding.

[0031] Specific implementation: When using this injection mold for children's bathtubs, first install the injection mold at the designated position of the injection molding machine according to requirements. Before injection molding, turn on the first electric push rod 16 and the second electric push rod 19. The first electric push rod 16 pushes the semi-circular block 6 to move, so that the inner wall of the semi-circular block 6 contacts the end face of the shaping module 13. The second electric push rod 19 pushes the rectangular block 14 out of the rectangular groove, so that the rectangular block 14 contacts the inside of the mold core 5. At this time, through the cooperation of the two semi-circular blocks 6 and the two rectangular blocks 14, the internal mold cavity is divided into two mold cavities at the top and bottom. The middle part of the mold cavity is completely filled by the rectangular block 14 and the semi-circular block 6. Then, the injection molding machine is used to feed materials to complete the synchronous injection molding of the top and bottom of the children's bathtub, replacing the need for separate injection molding of traditional children's folding bathtubs and improving the injection molding efficiency of children's bathtubs.
