AI Technical Summary

Technical Problem

Existing injection molds with secondary ejection structures require three ejection plates, resulting in larger mold size and weight, and higher costs.

Method used

The secondary ejection structure, consisting of components such as a slanted ejector head, a fixed block, a T-shaped drive block, a slanted ejector seat assembly, a reset block, and ejector pins, achieves secondary ejection of the product through the coordinated movement of the slanted ejector rod and the slanted ejector head, thereby reducing the overall size and weight of the mold.

Benefits of technology

This allows for ejection using a smaller mold structure, reducing mold costs and improving production efficiency.

Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to a secondary ejection structure for injection molds. Background Technology

[0002] Generally, injection molds with a secondary ejection structure require three ejector plates, resulting in larger mold size and weight, and consequently higher mold costs.

[0003] To address this, a secondary ejection structure for injection molds is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a secondary ejection structure for injection molds to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A secondary ejection structure for an injection mold includes an angled ejector head and a fixing block, wherein a T-shaped drive block is provided on one side of the fixing block;

[0007] One side of the T-shaped drive block is provided with an inclined top seat assembly;

[0008] The top of the T-shaped drive block is provided with a reset block;

[0009] The reset block is equipped with a pin connected to the T-shaped drive block on one side, and the pin is provided with a corresponding pin plate.

[0010] Furthermore, the T-shaped drive block is provided with a T-shaped block.

[0011] Furthermore, the top of the T-shaped block is provided with a slanted top rod.

[0012] Furthermore, a reset block is installed at the top of the inclined top seat assembly.

[0013] Furthermore, the top of the inclined push rod is provided with an inclined push head.

[0014] Furthermore, a limiting block is provided on one side of the ejector pin.

[0015] Furthermore, a stop is installed below the ejector plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This is a secondary ejection mechanism that utilizes a smaller mold structure to achieve the ejection target. After injection molding, the mold opens, and the injection molding machine's ejection mechanism, holding the ejector plate, moves upward, driving the secondary ejection assembly and ejector pins upward. Once the designed position is reached, a stop block restricts the upward movement of the secondary ejection assembly, while the ejector pins continue to move unaffected, ejecting the product. Attached Figure Description

[0018] Figure 1 This is a schematic diagram of the ejection structure of this utility model. Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example 1:

[0020] Please see Figure 1 This utility model provides a technical solution:

[0021] A secondary ejection structure for an injection mold includes an angled ejector head 1 and a fixing block 7. A T-shaped drive block 5 is provided on one side of the fixing block 7. An angled ejector seat assembly 6 is provided on one side of the T-shaped drive block 5. A reset block 3 is provided at the top of the T-shaped drive block 5. An ejector pin 8 connected to the T-shaped drive block 5 is installed on one side of the reset block 3. The ejector pin 8 is provided with a corresponding ejector plate 10. The T-shaped drive block 5 is provided with a T-shaped block 4. An angled ejector rod 2 is provided at the top of the T-shaped block 4. The reset block 3 is installed at the top of the angled ejector seat assembly 6. An angled ejector head 1 is provided at the top of the angled ejector rod 2. A limiting block 9 is provided on one side of the ejector pin 8. A stop block 7 is installed below the ejector plate 10.

[0022] Working principle:

[0023] One ejection: The ejector plate 10 moves upward, and the T-block 4, T-drive block 5, inclined ejector assembly 6 and ejector pin 8 move upward together until the T-block 4 touches the limit block 9. The inclined ejector completes the demolding of the structure, and one ejection is completed.

[0024] Secondary ejection: The ejector plate 10 continues to move upward. The inclined ejector structure is restricted by the limiting block 9 and cannot move. Under the action of force, the T-shaped drive block 5 in the inclined ejector seat assembly moves to the left. The inclined surface fits against the reset block 3. The ejector pin 8 continues to complete the ejection process until the limiting block of the ejector plate 10 moves to the bottom of the mold base, and the product is completely demolded.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
