Description

Technical Field

[0001] The invention relates to the technical field of molds, in particular to a mold insert slider mechanism. Background Art

[0002] Plastic molds are important tools in the plastic processing industry. They are used in conjunction with plastic molding machines to provide complete configurations and precise dimensions for plastic products. They are widely used in many fields such as automobiles, home appliances, electronic communications, and daily necessities. Due to the diversity of plastic varieties and processing methods, the types and structures of plastic molds are also diverse. They mainly include combined molds such as compression molding, extrusion molding, injection molding, blow molding, and low-foaming molding. These molds can process plastic products of different shapes and sizes through the coordinated changes of male and female molds and auxiliary molding systems. With the rapid development of the plastics industry and the expansion of the application range of plastic products, plastic molds are also developing continuously. Modern plastic molds are developing in the direction of large-scale and precision, while focusing on shortening the production cycle and improving mold accuracy.

[0003] At present, the traditional mold insert slider mechanism usually uses a simple guide rail and slider, lacking a precise guide and limit mechanism, which causes the slider to easily deflect and get stuck during the insert process, affecting the molding accuracy and production efficiency of the mold. At the same time, due to the lack of an effective elastic limit mechanism, the slider is prone to excessive movement when subjected to external forces, causing damage to the mold structure and shortening the service life of the mold. Summary of the invention

[0004] The present invention provides a mold insert slider mechanism, which solves the above problems existing in the use process of the prior art.

[0005] The technical solution of the present invention is achieved in this way:

[0006] The cam is provided with a plurality of guide rails, each of which is provided with a plurality of guide rails, and the guide rails are provided with a plurality of guide rails, each of which is provided with a plurality of guide rails.

[0007] Preferably, the elastic limit mechanism includes an elastic limit block, a spring cover and a spring, and the spring limit block, spring and spring cover are arranged in the elastic channel in sequence, wherein the elastic limit block forms a limited bottom surface facing the limiting opening, the lower end of the spring is arranged on the elastic limit block, and the upper end of the spring is arranged on the spring cover, so that when the elastic limit block is pressurized, it will shrink along the direction of the elastic channel.

[0008] Preferably, a connecting column is also included, which is formed with a mounting ring seat and a ring arranged along the axial direction of the connecting column, and a conical ring is formed between the ring and the end face of the terminal, and the inclination of the conical ring is the same as the above-mentioned slider guide end face.

[0009] Preferably, two slider pressure strips are provided to form two symmetrical inner slideways.

[0010] Preferably, the elastic limiting block is provided with three spring mounting holes, and each spring mounting hole is provided with a spring.

[0011] Preferably, a slider stopper is also installed, and the slider stopper is formed at the ends of the two slider guide rail blocks to serve as a limit end to resist the slider seat.

[0012] Through the above scheme, it can be seen that this scheme has the following characteristics:

[0013] (1) The cooperation between the inclined guide column and the slider seat, as well as the inner slide formed by the slider strip and the slideway, provide precise and stable guidance for the slider. This design ensures the precise alignment and smooth movement of the slider during the opening and closing process of the mold, thereby improving the accuracy and reliability of the mold.

[0014] (2) The components such as the top cover, slider seat, slider and slider guide block adopt modular design, which is easy to disassemble, replace and repair. This design not only improves the maintainability of the mold, but also reduces the maintenance cost.

[0015] (3) The elastic limit mechanism design realizes precise control and limit of the slider's moving position through the interaction between the elastic channel and the limit opening of the slider guide block. This design allows the slider to have a certain elastic movement space when subjected to external force, but ensures that it can stop stably when reaching the predetermined position, thereby improving the stability and safety of the mold.

[0016] (4) The design of the slider guide block, especially the slider guide end surface, moves with the elastic limit mechanism to reduce friction and wear during the sliding process. This design not only improves the sliding efficiency of the slider, but also extends the service life of the mold.

[0017] (5) The slider is equipped with a core insertion port to facilitate the insertion operation. This design simplifies the assembly and debugging process of the mold and improves production efficiency.

[0018] In summary, the technical features of the mold insert slider mechanism are mainly reflected in precision guidance, modular design, elastic limit, efficient sliding and easy insert operation. These features make the mechanism perform well in the process of mold manufacturing and use, and improve the precision, stability and production efficiency of the mold. It makes it convenient and quick for mold injection workers to install the insert, reduces the risk of die pressing, and can be used on both horizontal and vertical machines.

The above-mentioned slider seat 3 is formed with an outer slide bar 31 arranged on the inner slideway, and a slider guide block 2 is installed between the slider seat 3 and the slider 5. One end of the slider guide block 2 is arranged in the slider seat channel 30 opened in the slider seat, and the other section is processed into a limited opening 22 and is arranged in the limited channel 51 opened in the slider 5. The slider 5 is provided with an elastic channel 52 facing the limited channel and a plug-in core socket 53. The above-mentioned elastic limiting mechanism is arranged on the slider and limits the limiting opening of the slider guide block through the elastic channel. The slider guide block 2 has a slider guide end face 21, and the slider guide block 2 moves with the elastic limiting mechanism through the slider guide end face 21.

[0039] Among them, the elastic limit mechanism includes an elastic limit block 6, a spring cover 8 and a spring 10, and the spring limit block 6, the spring 10 and the spring cover 8 are arranged in the elastic channel 52 in sequence, wherein the elastic limit block 6 faces the limit opening 22 to form a limited bottom surface 62, the lower end of the spring 10 is arranged on the elastic limit block 6, and the upper end of the spring 10 is arranged on the spring cover 8, so that when the elastic limit block is pressed, it will shrink along the elastic channel direction. It also includes a connecting column 7, which is formed with a mounting ring seat 71 and a circular ring 72 formed along the axial direction of the connecting column, and a conical circular ring 73 is formed between the circular ring 72 and the end face of the terminal, and the inclination of the conical circular ring is the same as that of the above-mentioned slider guide end face, so that the sliding is smoother and there will be no jamming. The slider pressure strip 11 is provided with two, forming two symmetrical inner slideways. The elastic limit block is provided with three spring mounting holes 61, and each spring mounting hole 61 is equipped with a spring 10. A slider stopper 4 is also installed, which is formed at the ends of the two slider guide rail blocks and serves as a limit end for resisting the slider seat.

[0040] Detailed description of this plan:

[0041] The slider strip is precisely installed on the slideway to form the inner slideway. The slider seat is processed to have an outer slide strip that fits tightly with the inner slideway. At the same time, the slider guide block is made, one end of which is embedded in the slider seat channel and the other end is processed with a limit opening to match the slider limit channel.

[0042] The design of the slider must include an elastic channel and an insert core socket, and reserve installation space for the elastic limit mechanism.

[0043] Assembly of the elastic limit mechanism: install the elastic limit block, spring and spring cover into the elastic channel of the slider in sequence. Make sure that the limit bottom surface of the elastic limit block faces the limit opening, and the two ends of the spring are fixed on the elastic limit block and the spring cover respectively to realize the elastic limit function.

[0044] Installation and adjustment of the connecting post: Install the connecting post. The mounting ring seat 71, the circular ring 72 and the tapered circular ring 73 of the connecting post are all integrally formed. The tapered circular ring formed by the circular ring and the end face of the connecting post has an inclination consistent with the guide end face of the slider to optimize the sliding effect.

[0045] Slider layer 11 and inner slide arrangement: If a double slider layer design is adopted, ensure that they are symmetrically installed on the slide to form two parallel inner slides, thereby enhancing the stability and guidance of the slider.

[0046] Installation of multiple springs 10: If the elastic limit block is provided with multiple spring installation holes, a spring is installed in each hole to improve the stability and response speed of the elastic limit mechanism.

[0047] Installation of the slider stopper 4: A slider stopper is formed at the end of the slider guide block as a limit end of the slider seat to prevent the slider from exceeding a predetermined range and protect the mold structure.

[0048] Through the close cooperation of the inclined guide column, the slider seat, the slider guide block and the inner slide, the slider is accurately guided and limited, ensuring the accuracy and stability of the mold insertion process. The elastic limit mechanism uses the elastic force of the spring to enable the elastic limit block to move flexibly and stabilize the limit, adapting to different insert thicknesses and mold wear conditions, and extending the service life of the mold. The conical ring design of the connecting column matches the guide end face of the slider, optimizing the sliding effect, reducing friction and wear, and improving the sliding smoothness and durability of the mold.

[0049] The double slider bead design forms a symmetrical inner slideway, which enhances the stability and balance of the slider and prevents the slider from deflecting or getting stuck during movement.

[0050] The multi-spring installation design improves the response speed and reliability of the elastic limit mechanism, ensuring a stable and accurate limit effect even during high-speed insertion.

[0051] In summary, this technical implementation method significantly improves the performance and use effect of the mold insert slider mechanism through precise guidance, elastic limiting, optimized sliding, enhanced stability and balance, improved response speed and reliability, and protection of mold structure.
