Description

Technical Field

[0001] The utility model relates to the technical field of core pulling of shower head molds, and specifically relates to a core pulling mechanism for a shower head mold. Background Art

[0002] Core pulling of a shower head mold is an important link in the plastic injection molding process. It involves pulling out the core inside the mold from the already molded shower head product to form cavities, channels, or other complex structures inside the product. This process is achieved through a dedicated core pulling mechanism, which usually includes a power source, a core pulling rod, a guide rail, a positioning mechanism, and a safety device, etc. They work together to ensure that the core can be accurately and smoothly pulled out, so that the product can be smoothly demolded while maintaining the accuracy and integrity of the product. This process poses relatively high requirements for mold design and manufacturing, and various factors such as the shape, size, production efficiency, and durability of the mold need to be considered.

[0003] Currently, when pulling the core of a shower head mold, generally a cylinder, an inclined sliding rod, and corresponding sliding structures are required to complete the core pulling work of the shower head mold. The sliding structure is generally an electric sliding table or an electric lead screw. There are relatively many core pulling structures set. When one of the electric core pulling components fails, subsequent normal core pulling cannot be carried out, and at the same time, the overall core pulling structure becomes more complex, increasing the operation difficulty. Therefore, a core pulling mechanism for a shower head mold is proposed. Content of the Utility Model

A limiting clamping rod 15 is slidably connected inside the fixed plate 14. A limiting ring 16 is fixedly installed on the outer peripheral wall of the limiting clamping rod 15. A U-shaped sliding groove is formed in the right side wall of the fixed plate 14. The limiting clamping rod 15 is slidably connected inside the U-shaped sliding groove and is of a suitable size.

At this time, the air cylinder 4 can be started to drive the upper die body 3 to move upward. At this time, the core-pulling seat 12 drives the core-pulling shaft 19 to move upward under the pulling force of the limiting clamping rod 15. At this time, the core-pulling shaft 19 will drive the entire shower head mold to move upward. At this time, the core-pulling work of the shower head mold is completed.
