Description

Technical Field

[0002] A water pitcher is a common household appliance, mainly used to store cold water. Plastic water pitchers are popular because they are easy to manufacture and inexpensive.

[0003] Like other plastic parts, the production of cold water bottles relies on matching molds and injection molding machines. Since the spout of the cold water bottle needs to have grooves that cooperate with the lid, the existing cold water bottle molds have to use cylinders for demolding in order to make these grooves and prevent the two molding mechanisms used to form the inner and outer grooves from interfering with each other. This increases the manufacturing cost and makes the structure more complex. In addition, the complexity of installation, debugging and maintenance has also increased significantly, which requires further improvement. Utility Model Content

[0026] An arc-shaped molding groove 311 is provided on the side of the outer forming block 31 facing the conical core 35, which cooperates with the outer wall of the conical core 35.

[0027] A cavity 352 is provided on the upper and lower outer walls of the annular boss 351. Correspondingly, a protrusion 331 is formed on the side of the forming block 33 inside the spout facing the conical core 35, which cooperates with the cavity 352.

[0032] Working principle:

[0033] The feed block 5 and the bottom block 7 are respectively installed on the action mechanism and the machine body of the injection molding machine. The action mechanism drives the feed block 5 to move backward, and then the material distribution block 4 drives the molding module 1 to move towards the positioning module 2 until the two are joined together (existing technology), so that the conical core 35 is inserted into the conical mold hole 11.

[0034] During the movement of the molding module 1, the second traction column 34 in each spout molding unit will move backward, thereby forcing the molding block 33 inside the spout to move towards the conical core column 35 until it is inserted into the cavity 352 on the protrusion 331. At this time, the arc-shaped splicing surface 332 fills the opening of the cavity 352 from the inside out and connects with the outer wall of the annular protrusion 351. During the movement of the molding module 1, each first traction column 32 will gradually be inserted into a corresponding spout outer molding block 31, thereby forcing each spout outer molding block 31 to move towards the conical core column 35 until the arc-shaped step surface 312 surrounds the periphery of the annular protrusion 351.

[0035] Subsequently, the molten material enters the space between the conical core 35 and the conical mold hole 11 through the gate in the feed block 5 and the sprue in the distribution block 4, and after cooling, it forms a cold water jug ​​(existing technology).

[0036] Then, the feeding block 5 is driven forward by the action mechanism, and the forming module 1 is driven forward and away from the positioning module 2 by the material distribution block 4. Then the formed cold water bottle can be taken out (existing technology).

[0037] This invention can form grooves that match the lid on the inside and outside of the spout of a cold water kettle without the use of a cylinder, and can be easily demolded. Moreover, the two spout forming units will not interfere with each other, thereby reducing manufacturing costs and simplifying the structure. At the same time, it also effectively reduces the complexity of installation, debugging and maintenance.
