Description

Technical Field

[0001] The utility model relates to the technical field of molds, and more specifically to a mold anti-collision structure. Background Art

[0002] Molds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging molding, smelting, stamping and other methods. In short, molds are tools used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material.

[0003] Based on the above, the inventors found that the needle plate on the existing mold is often equipped with a demoulding mechanism, and most of the demoulding structures are large in number and relatively complex. During the mold closing process, the needle plate often fails to return to its original position in time, causing the mother mold plate to collide with the demoulding structure on the needle plate during mold closing, causing damage to the demoulding structure and affecting its normal workpiece processing. Therefore, in view of this, the existing structure is studied and improved, and a mold anti-collision structure is provided, in order to achieve a more practical purpose. Utility Model Content

[0034] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0035] Example:

[0036] See also Figure 1-4 A mold anti-collision structure comprises a lower fixed plate 1, mold feet 2 are fixedly connected to both sides of the top of the lower fixed plate 1, a needle plate 3 is arranged between the two mold feet 2, a male mold plate 4 is installed on the top of the mold feet 2, a female mold plate 5 is arranged above the male mold plate 4, a mold core 6 is arranged between the male mold plate 4 and the female mold plate 5, an upper fixed plate 7 is fixedly connected to the top of the female mold plate 5, anti-collision components 8 are arranged at both ends of the male mold plate 4, and the two anti-collision components 8 are symmetrical about the center point of the male mold plate 4;

[0037] The anti-collision assembly 8 includes a push rod 1 801, a push rod 2 802 and a push block 803. The push rod 1 801 is fixed to the end of the female template 5 by a fastening bolt, the push rod 2 802 is installed to the end of the male template 4 by a movable bolt 804, and the push block 803 is fixed to the end of the needle plate 3 by a fastening bolt. One end of the push rod 2 802 is in contact with the top of the push block 803. When in use, the push rod 2 802 is installed at the end of the male template 4 by the movable bolt 804, but the movable bolt 804 is not fully tightened to ensure that the push rod There is a certain friction force between the second push rod 802 and the end surface of the male template 4. When the thrust of the push rod 1 801 applied to the second push rod 802 is greater than the friction force, the second push rod 802 can swing downward. When the thrust of the push rod 1 801 applied to the second push rod 802 is less than the friction force, the second push rod 802 can remain relatively still and will not swing downward. This is convenient for closing the mold and can ensure a smooth mold closing operation, prevent the mold closing speed from being too fast and colliding with the needle plate 3, causing damage to the needle plate 3, thereby improving the stability of its operation.

[0038] See also Figure 2 The top rod 801 is vertically arranged and located on one side of the top block 803.

[0039] See also Figure 2 A positioning block 9 is provided on one side of the push rod 801, and the positioning block 9 is fixed to the end of the male template 4 by a fastening bolt. When in use, the positioning block 9 can prevent the push rod 801 from swinging after long-term use.

[0040] See also Figure 2 A positioning column 10 is provided on the other side of the push rod 1 801, and the positioning column 10 is fixed to the end of the male template 4 by a fastening bolt. When in use, the positioning column 10 can prevent the push rod 2 802 from rotating excessively, ensuring that the movable end of the push rod 2 802 is located below its positioning column 10.

[0041] See also Figure 2 The positioning column 10 is located above one end of the second push rod 802.

[0042] See also Figure 4 The needle plate 3 includes a lower ejector plate 301 and an upper ejector plate 302 . A plurality of ejector pins 303 are arranged on the lower ejector plate 301 . The top ends of the ejector pins 303 pass through the upper ejector plate 302 and extend to the inside of the mold core 6 .

[0043] See also Figure 2 and Figure 4 The ejector block 803 is fixed to the end of the lower ejector plate 301 .

[0044] When in use: the anti-collision component 8 composed of the ejector pin 1 801, the ejector pin 2 802 and the ejector block 803, when the mother mold plate 5 moves downward during the mold closing process, can drive the ejector pin 1 801 to push the ejector pin 2 802 downward. After the ejector pin 2 802 is subjected to the downward thrust, its movable end can rotate downward and push the ejector block 803 to move downward accordingly. The downward movement of the ejector block 803 can drive the needle plate 3 to move downward until it returns to its initial state, thereby avoiding the phenomenon that the mold core 6 at the bottom of the mother mold plate 5 collides with the ejector pin 303 that has not been reset when the mother mold plate 5 is closed, thereby protecting the mold and ensuring that the mold can process the workpiece normally.
