Description

Technical Field

[0001] This utility model belongs to the field of mold technology, specifically relating to a long carbon fiber PA12 composite material mold with high efficiency in core replacement. Background Technology

[0002] In existing technologies, the manufacture of complex components using long carbon fiber reinforced PA12 (polyamide 12) composite materials often requires specialized molds. These molds typically have the mold core tightly embedded within the mold body. However, when it's necessary to replace the mold core with a different size to meet different product requirements or for maintenance, the existing mold structure has significant drawbacks: the replacement process is extremely cumbersome and inefficient. Operators cannot directly remove the mold core; they must first disassemble the entire mold from the production equipment (such as a compressor body) and then painstakingly tap the mold core bit by bit with tools to barely remove it. This process is not only time-consuming and labor-intensive, severely slowing down production efficiency and increasing downtime, but the repeated tapping operations can easily damage the delicate mold core surface and the internal structure of the mold body, causing scratches, dents, or even deformation, directly affecting the molding quality and precision of the final product and shortening the lifespan of the expensive mold. Therefore, there is an urgent need for a long carbon fiber PA12 composite material mold solution that enables rapid, convenient, and non-destructive replacement of the mold core.

[0003] This invention attempts to solve or at least alleviate such problems by providing a long carbon fiber PA12 composite material mold with high core-changing efficiency. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The terms “comprising,” “including,” etc., as used herein indicate the presence of the stated features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0017] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein are to be interpreted in a manner consistent with the context of this specification, and not in an idealized or overly rigid way.

[0018] In the embodiments, by Figure 1-6A high-efficiency long carbon fiber PA12 composite material mold for core replacement is provided, comprising: a mold 1, the mold 1 including a mounting part 11 and a vertically arranged slot 17 in the mounting part 11, the front of the mold 1 having a first through hole 16; a mold core 2, the front of the mold core 2 having a first screw hole 22, the first screw hole 22 being the same size as the first through hole 16, the mold core 2 being able to be inserted into the slot 17; a limiting protrusion 18 being provided at the bottom of the mold 1, and a notch 23 being provided at the bottom of the mold core 2, the limiting protrusion 18 matching the notch 23; and a template 12 being provided on the side of the mounting part 11. The mold core 2 is vertically inserted and removed through the slot 17, and the precise matching of the limiting protrusion 18 and the notch 23 completely eliminates installation misalignment; the upward-opening slot 17 allows the mold core 2 to be directly removed without disassembling the mold 1; the template 12 provides an installation base for the lateral mechanism, significantly improving the overall structural integrity.

[0019] In a preferred embodiment of this utility model, a clamping member 13 is further provided on the side of the mold 1. The clamping member 13 is connected to the mounting part 11 via a locking member 15. The locking member 15 includes a locking member protrusion 151, and a second locking member screw hole 152 is provided in the locking member protrusion 151, into which a bolt can be inserted. The clamping member 13 is mounted on the mounting part 11 via the locking member 15, further ensuring the stability of the mold core 2 after it is inserted into the slot 17.

[0020] In a preferred embodiment of this utility model, a locking spring 153 is provided at the bottom of the second screw hole 152 of the locking member, and a locking pressing plate 154 is installed at the end of the locking spring 153. The spring 153 generates a continuous reverse elastic force when the bolt is screwed in, causing the pressing plate 154 to automatically compensate for vibration or thermal deformation gaps, significantly improving the anti-loosening reliability of the locking member 15 under high-pressure conditions.

[0021] As a preferred embodiment of this utility model, a lifting ring 24 is provided on the top of the mold core 2. The lifting ring 24 supports the vertical lifting of the mold core 2 by hoisting equipment, completely avoiding surface damage caused by manual prying, and is especially suitable for the safe and damage-free replacement of large mold cores 2 weighing >100kg.

[0022] In a preferred embodiment of this invention, the mold 1 has a second through hole 19 on its side, through which a push rod can extend to push the mold core 2. The second through hole 19 ensures that the push rod can press against the mold core 2.

[0023] In a preferred embodiment of this utility model, a template 12 is provided next to the mounting part 11, and an insertion hole is provided on the side of the template 12. A guide post 14 is provided on the side of the clamping member 13. When the mold core 2 is pushed, the guide post 14 can be inserted into the insertion hole of the template 12. The cooperation between the guide post 14 and the insertion hole ensures that there is no deviation during the lifting process of the mold core 2, realizes precise linear guidance, and effectively prevents the mold core 2 from being scratched and damaged by the inner wall of the groove 17.

[0024] In a preferred embodiment of this invention, the mold 1 is horizontally mounted on the compressor body 3. This horizontal mounting design directly connects to the compressor body 3 production line, eliminating the secondary positioning process required by traditional molds and significantly improving production continuity. The specific arrangement of the mold 1 and the compressor body 3 is existing technology.

[0025] Working Principle: During operation, the mold core 2 is vertically inserted into the slot 17 of the mounting portion 11 of the mold 1. The notch 23 at the bottom of the mold core 2 matches and positions itself against the limiting protrusion 18 at the bottom of the mold 1, preventing misalignment during installation. When the mold core needs replacement, the bolt in the first through hole 16 can be removed to release the limiting position of the mold core 2. Then, the lifting ring 24 can be pulled upwards to remove the mold core directly. The new mold core can be inserted in reverse. The clamping member 13, through the locking member 15, assists in fixing the mold structure. When the bolt is screwed into the second screw hole 152, the bolt pushes the pressing plate 154 inwards, and the spring 153 generates a counterforce with the bolt, strengthening the bolt's tightening effect. The insertion hole on the side of the template 12 cooperates with the guide post 14 on the side of the clamping member 13, providing guidance when the mold core is pushed.

[0026] In summary, this invention significantly improves the core-changing efficiency and ease of operation of long carbon fiber PA12 composite material molds, while effectively protecting mold precision and service life. Its core lies in a complete overhaul of the core-changing method: operators only need to unscrew the bolts to release the limiting mechanism, and the core can be directly and without damage removed vertically from the upward-opening slot using the lifting ring. This completely eliminates the outdated process of disassembling the entire mold and laboriously hammering the core with tools. This brings several significant advantages: First, core-changing operations become extremely simple and quick, greatly reducing downtime for mold changes and significantly improving equipment utilization and production efficiency; second, it completely avoids mold disassembly and hammering operations, saving time and effort, and more importantly, greatly reducing the risk of scratches, deformation, and other physical damage to the core and mold body during replacement, effectively ensuring the long-term precision of the mold and the quality stability of the molded products; finally, the locking mechanism significantly enhances the reliability of bolt tightening through spring reaction force, ensuring the overall stability of the mold during the molding process, while the cooperation between the guide post and the insertion hole improves the smoothness of operation and guiding accuracy. With a reasonable overall design and reliable operation, it is particularly suitable for high-efficiency production scenarios that require frequent mold core replacement, resulting in outstanding overall benefits.

[0027] 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.
