Description

Technical Field

[0001] This utility model belongs to the technical field of plastic mold demolding mechanism, specifically the inverted strong demolding mechanism in a very small space. Background Technology

[0002] In plastic injection molding, various complex structures often appear on the product, including undercut structures. An undercut structure refers to a part of the product obstructing the demolding direction, preventing the product from being directly removed when the mold opens. Traditionally, this problem is solved by using ejector mechanisms such as angled ejectors or sliding blocks. However, these traditional methods face numerous challenges when implementing undercut demolding in extremely small spaces.

[0003] Space constraints: In some products, the space occupied by the inverted structure is very small. Traditional angled top structures or slider structures cannot be placed in these small spaces due to their large size.

[0004] Cost considerations: Traditional demolding mechanisms are usually complex in structure, requiring more parts and processing steps, which increases the manufacturing cost of the mold. Utility Model Content

[0025] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Example 1

[0027] Please see Figures 1-6 As shown, this application provides a minimal space inverted snap-off mechanism, including template 1 and template 2. Template 1 is provided with a mold core 3, and template 2 is provided with a connecting plate 4 above it.

[0028] A connecting plate 2 5 is fixedly connected to the top of the connecting plate 4. An ejection mechanism 6 for ejecting the mold core 3 is provided between the connecting plate 4 and the template 2. The ejection mechanism 6 passes through the template 1. By utilizing the ejection mechanism 6, the ejection and demolding operation of the mold core can be achieved efficiently and accurately in a very small space. This feature greatly expands the application range of injection molds in the manufacturing of complex structure products. Moreover, the structure is simple and clear, significantly reducing the number of parts compared to traditional demolding methods, thereby effectively reducing the manufacturing complexity and overall cost of the mold. This structural optimization not only improves the reliability and durability of the mold, but also shortens the mold manufacturing cycle and improves production efficiency.

[0029] The ejection mechanism 6 includes a return pin 61 mounted on the connecting plate 4 and an auxiliary structure 62 fixedly connected to the top of the connecting plate 4. A limiting tube 63 is fixedly connected to the top of the return pin 61, and a buckle pin 64 is mounted on the limiting tube 63. The connecting plate 4 and connecting plate 5 are raised by the template 2, which in turn raises the ejection mechanism 6 as a whole. The top of the buckle pin 64 is then inserted into the mold core 3, and the top of the auxiliary structure 62 contacts the bottom of the mold core 3. As the ejection mechanism 6 rises, the limiting tube 63 contacts the template 1, causing the spring 10 to gradually compress. The buckle pin 64 then stops moving, while the auxiliary structure 62 continues to move upward, thus ejecting the mold core 3 and disengaging it from the buckle.

[0030] The auxiliary structure 62 consists of ejector pin 1 621, ejector pin 2 622, ejector pin 3 623, and ejector pin 4 624, with multiple ejector pins 1 621, 2 ejector pins 2 622, and 3 ejector pin 3 623. There are 3 ejector pins 1 621, 2 ejector pins 2 622, 2 ejector pins 3 623, and 1 ejector pin 4 624.

[0031] The top of the template 2 has a groove 7, and the bottom of the template 2 has a movable groove 8 that communicates with the groove 7.

[0032] The bottom of the return pin 61 is fixedly connected to a connecting rod 9, and the connecting rod 9 is slidably connected to the movable groove 8.

[0033] A spring 10 is sleeved on the outside of the connecting rod 9, and the spring 10 is located in the groove 7.

[0034] The ejector pins 621, 622, 623, and 624 are all designed to be narrower at the top and wider at the bottom.

[0035] The limiting tube 63 is slidably connected to the connecting plate 5, and the return pin 61 is slidably connected to the connecting plate 4.

[0036] The working principle of this utility model is as follows: The template 2 drives the connecting plate 4 and the connecting plate 5 to rise, which in turn drives the ejection mechanism 6 to rise as a whole. Then, the top of the undercut pin 64 is inserted into the mold core 3, and the top of the auxiliary structure 62 contacts the bottom of the mold core 3. Then, as the ejection mechanism 6 rises as a whole, the limiting tube 63 contacts the template 1, so the spring 10 is gradually compressed. Then, the undercut pin 64 stops moving, while the auxiliary structure 62 continues to move upward, thereby ejecting the mold core 3 and disengaging it from the undercut.

[0037] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
