AI Technical Summary
During the injection molding process, spring failure prevents the spring block from ejecting properly, affecting product quality and production line progress.
Design a sliding spring hook structure, including a limit block, hook, spring block, pin and spring. Through the cooperation of hook and spring, ensure smooth demolding even when spring fails.
When the spring fails, the hook structure allows the spring block to smoothly detach from the molding die, ensuring smooth product demolding, avoiding the risk of mold compression, and improving production efficiency and product quality.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of mold slide demolding, and in particular to a slide spring hook structure. Background Technology
[0002] Cavity products have an inverted structure during production. The spring block is inserted downward into the inverted structure on the molding die, which restricts the stability of the product during injection molding. During demolding, the spring controls the limit block to rise in the molding die, so that the spring block is released from the product. If the spring fails, the spring block cannot pop out normally, which will cause the mold to be pressed, affecting the progress of the production line and the quality of the product. Utility Model Content
[0003] One objective of this invention is to provide a sliding spring hook structure to solve the problems existing in the prior art.
[0004] To achieve this objective, the present invention adopts the following technical solution:
[0005] A sliding spring hook structure includes a limiting block and a forming mold. The forming mold has a limiting cavity in the middle, and the limiting block is located in the limiting cavity. A first spring connects the limiting block and the forming mold. Spring blocks are provided on both sides of the limiting block. The lower end of the spring block passes through the limiting block and the forming mold and is inserted into the product. A hook and a spring block buckle are installed in the middle of the limiting block. A pin is horizontally installed inside the limiting block. The pin passes through the spring block and the spring block buckle. A second spring connects the lower end of the spring block buckle to the limiting block. The upper end of the spring block buckle is engaged with the hook. The lower end of the spring block buckle is fastened to the forming mold.
[0006] As a preferred technical solution, a limiting post is installed on the limiting block, and the limiting post passes through the limiting block and is inserted into the molding die.
[0007] As a preferred technical solution, a limiting sleeve is fitted on the outer side of the limiting post.
[0008] As a preferred technical solution, the upper cross-sectional dimension of the spring block is larger than the lower cross-sectional dimension of the spring block.
[0009] As a preferred technical solution, the molding die is provided with a through hole, and the lower end of the spring block passes through the through hole.
[0010] The beneficial effects of this utility model are as follows: It provides a sliding spring block hook structure. When demolding, if the first spring fails, the hook can be lifted upwards, causing the second spring to rotate the spring block. The limiting block can then drive the spring block to rise, allowing the product to be successfully demolded. Attached Figure Description

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0019] like Figures 1 to 4 As shown in this embodiment, a sliding spring hook structure includes a limiting block 1 and a forming mold 2. A limiting cavity 3 is provided in the middle of the forming mold 2, and the limiting block 1 is located in the limiting cavity 3. A first spring 4 is connected between the limiting block 1 and the forming mold 2. Spring blocks 5 are provided on both sides of the limiting block 1. The lower end of the spring block 5 passes through the limiting block 1 and the forming mold 2 and is inserted into the product 13. A hook 6 and a spring block buckle 7 are installed in the middle of the limiting block 1. A pin 8 is horizontally installed inside the limiting block 1. The pin 8 passes through the spring block 5 and the spring block buckle 7. A second spring 9 is connected between the lower end of the spring block buckle 7 and the limiting block 1. The upper end of the spring block buckle 7 is engaged with the hook 6. The lower end of the spring block buckle 7 is fastened to the forming mold 2.
[0020] Specifically, a limiting post 10 is installed on the limiting block 1. The limiting post 10 passes through the limiting block 1 and is inserted into the forming mold 2. A limiting sleeve 11 is fitted on the outer side of the limiting post 10. The upper cross-sectional dimension of the spring block 5 is larger than the lower cross-sectional dimension of the spring block 5. A through hole 12 is provided on the forming mold 2. The lower end of the spring block 5 passes through the through hole 12.
[0021] In normal demolding conditions, the first spring 4 lifts the spring block 5 upwards. Under the action of the pin 8, the entire limiting block 1 rises, allowing the upper-larger, lower-smaller spring block 5 to detach from the product 13, and the product 13 can also detach from the molding mold 2. If the first spring 4 fails, the front mold will pull the hook 6 upwards. Under the action of mutual locking, the spring block buckle 7 is pulled open, and the second spring 9 pops out, causing the spring block buckle 7 to rotate around the pin 8, thereby causing the lower end of the spring block buckle 7 to detach from the molding mold 2. After the limiting block 1 and the molding mold 2 are separated, the spring block 5 will also rise with the limiting block 1, which can also allow the product 13 to detach from the molding mold 2 for demolding.
[0022] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles applied thereto. Within the scope of the technology disclosed in this utility model, any variations or substitutions that are easily conceived by those skilled in the art should be covered within the protection scope of this utility model.
