Technical Field

[0001] The utility model relates to the field of products related to automobile molds, and more specifically, to an injection mold for automobile connectors that is easy to carry. Background Technique

[0002] In the latest national standard of our country, the terms and definitions of the types of automobiles and trailers have the following definition of an automobile: a vehicle driven by power and having 4 or more wheels and non-rail bearing. Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of the injection molding method are fast production speed, high efficiency, automation of operation, a variety of flower patterns and varieties, the shape can range from simple to complex, the size can range from large to small, and the product size is accurate, the product is easy to update, and it can form parts with complex shapes. Injection molding is suitable for forming processing fields such as mass production and products with complex shapes. However, the current injection molds have the problem of being inconvenient for cooling. During use, when injecting the colloid inside the mold, the cooling speed is slow, which affects the mold ejection speed. Therefore, improvement is needed.

[0003] Regarding the above problems and the technical problem that the existing injection molds are inconvenient for cooling, after a large amount of retrieval, an injection mold for automobile connectors that is easy to carry with the patent number CN215791587U is found, which includes a lifting sleeve. The top of the lifting sleeve is fixedly installed with a lifting rod, and a fixing groove is opened on the front of the lifting rod, and a screw rod is fixedly installed on the front of the fixing groove; through the settings of the lifting sleeve, the lifting rod, the fixing groove and the screw rod, the function of facilitating the coincidence of the upper and lower molds is achieved. During use, the lifting rod can be pulled upward to extract and lift inside the lifting sleeve, and then the screw rod is rotated to the right so that when the lifting rod is lifted to a suitable position, it is fixed with the lifting sleeve, thus achieving the purpose of facilitating demolding. And the settings of the mold body, the mold groove, the mold block and the support plate achieve the function of facilitating injection molding. During use, the unformed liquid can be poured into the mold groove, and then the lifting sleeve and the lifting rod are used to lift it to make the mold groove coincide with the mold block, and then the molding is achieved. However, the technical solution provided by this patent has the following problems:

[0032] Working principle: When in use, first inject cooling water into the water tank 14 from the water inlet 4. Then move and rotate the first rotating handle 9 to move the support plate 6 downward, and at the same time drive the upper die core 12 downward until the upper die core 12 is in close contact with the lower die core 13, so that the upper die core 12 and the lower die core 13 form a U090 - box body. Then inject the injection solution into the upper die core 12 and the lower die core 13. After the mold is formed, rotate the first rotating handle 9 in the reverse direction to separate the upper die core 12 from the lower die core 13. At this time, the formed mold can be taken out. At the same time, the second rotating handle 201 can also be rotated. The thread rotation directions at the left and right ends of the second threaded rod 202 are opposite. When the second threaded rod 202 is rotated, the sliding parts 204 at the front and rear ends move closer to the middle position together, and the distance between the two sliding parts 204 decreases. At this time, the connecting plate 207 will rotate upward, thereby pushing the connecting block 208 upward, and then driving the support plate 6 upward. The support plate 6 drives the ejector pin 206 upward. The ejector pin 206 enters the mold ejection hole to eject the mold. At this time, it will be very convenient to take out the mold. Finally, the cooling water is discharged from the water outlet 3 to complete the injection molding. And by providing a handle 5, it is more convenient to carry the injection mold.
