Description

Technical Field

[0001] This utility model relates to the field of injection molding technology, and in particular to a high-strength adjustable injection mold frame. Background Technology

[0002] Injection molds are core equipment for producing plastic products. In modern industrial production, it is often necessary to produce a series of products of different models and similar sizes using a single mold, or to make minor adjustments to the local features of the product. The traditional approach is to replace the entire mold or part of the mold core (insert), which is costly, time-consuming, and inefficient.

[0003] Furthermore, molds need to withstand extremely high cavity pressures (typically tens to hundreds of megapascals) during injection molding. Especially for large, deep-cavity products, the moving mold part is prone to elastic deformation, leading to problems such as flash (burrs) and dimensional deviations, which seriously affect mold life and product quality. Therefore, there is an urgent need for a new mold structure that can flexibly adjust cavity dimensions while possessing extremely high structural strength to withstand injection pressure. Utility Model Content

[0004] This invention solves the problems in related technologies by proposing a high-strength adjustable injection mold base. The locking mechanism in the quick-release mechanism allows for fine-tuning of the fixed and moving mold cores to adjust the required parting surface pressure, thereby improving the quality consistency of injection molded products. The support mechanism provides support for the fixed and moving mold cores after pressure adjustment, preventing flash or dimensional deviations caused by the elastic deformation of the moving mold core. In summary, this injection mold base effectively improves the quality and production efficiency of injection molded products through precise adjustment and stable support.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a high-strength adjustable injection mold base, including an upper mold base, a lower mold base disposed relative to the upper mold base, guide post sleeves disposed at the four peripheral corners of the upper mold base and the lower mold base, an upper mold base fixedly connected to the upper mold base, a lower mold base fixedly connected to the lower mold base, a fixed mold core connected to the upper mold base, a movable mold core connected to the lower mold base, and a quick-release mechanism for quick release of the fixed mold core and the movable mold core; The quick-release mechanism includes a locking mechanism and a support mechanism.

[0006] By adopting the above technical solution, the upper and lower mold bases are secured by guide post sleeves at their four corners to ensure stability and guiding accuracy. The upper mold base is fixed to the upper mold base and connected to the fixed mold core, achieving partial structural connection of the upper mold; the lower mold base is fixed to the lower mold base and connected to the moving mold core, achieving partial structural connection of the lower mold. The locking mechanism in the quick-release mechanism allows for fine-tuning of the fixed and moving mold cores to adjust the required mold closing surface pressure, thereby improving the consistency of injection molded product quality. The support mechanism provides support for the fixed and moving mold cores after pressure adjustment, preventing flash or dimensional deviations caused by the elastic deformation of the moving mold core. In summary, this injection mold base effectively improves the quality and production efficiency of injection molded products through precise adjustment and stable support.

[0007] As a preferred embodiment, the locking mechanism includes a support base fixedly disposed on the fixed mold core and the moving mold core at the ends away from the mold closing surface, a first slot disposed on one side of the outer periphery of the fixed mold core and the moving mold core, a second slot disposed on the other side of the outer periphery of the fixed mold core and the moving mold core and mirrored with the first slot, a first locking pin slidably connected to the first slot, a second locking pin slidably connected to the second slot, a fixing support for fixing the first locking pin and the second locking pin, and an adjusting handle fixedly disposed on the outer periphery of the moving mold core and the fixed mold core. The fixing support is fixedly connected to the upper mold base and the lower mold base respectively.

[0008] By adopting the above technical solution, the support base is fixedly installed at the end of the fixed mold core and the moving mold core away from the mold closing surface for support and stability; the first and second slots are respectively installed on both sides of the outer periphery of the fixed mold core and the moving mold core, and are mirror images of each other for sliding of the first locking post and the second locking post; the first locking post and the second locking post are slidably connected to the first slot and the second slot respectively for adjusting the relative height of the fixed mold core and the moving mold core; the fixed support is used to fix and maintain the position of the first locking post and the second locking post, and facilitates fixing them by adjusting the handle.

[0009] As a preferred embodiment, one end of the first card slot and the second card slot are respectively set as open ends, and the other end of the first card slot and the second card slot are set as closed ends.

[0010] By adopting the above technical solution, the first and second slots have one open end and the other closed end, facilitating the insertion and removal of the first and second locking pins. Specifically, the first and second locking pins are aligned and moved towards the open end through the relative rotation of the fixed mold core and the moving mold core, thereby easily removing them from the first and second slots and achieving the purpose of quickly replacing the fixed mold core and the moving mold core. This design simplifies the replacement process and significantly improves operational efficiency.

[0011] As a preferred embodiment, the support assembly includes support cavities respectively disposed on the upper mold base and the lower mold base, a telescopic rod disposed in the middle of the support cavity, a support plate connected to the telescopic end of the telescopic rod, and a support spring for supporting the support plate. The inner wall of the support cavity is tangent to the outer periphery of the support base, and the outer diameter of the support base is smaller than the outer diameter of the fixed mold core and the moving mold core, respectively.

[0012] By adopting the above technical solution, both the upper and lower mold bases are equipped with support cavities to guide and support the sliding of the support base. The shape of the support cavity is consistent with the outer periphery of the support base, ensuring that the support base can move smoothly within it. The inner wall of the support cavity is tangential to the outer periphery of the support base, allowing the support base to slide freely during mold operation. A telescopic rod located in the middle of the support cavity has its telescopic end connected to a support plate, allowing the position of the support plate to be adjusted as needed. Driven by the telescopic rod, the support plate can be adjusted to a higher or lower position, thereby better supporting the support base. In addition, a support spring is used to support the support plate, ensuring that the support plate remains stably in a suitable balance position, thus ensuring the stability of the support base.

[0013] As a preferred embodiment, one end of the support spring is fixedly connected to the lower end face of the support plate, and the other end of the support spring is fixedly connected to the lower end face of the support cavity.

[0014] By adopting the above technical solution, one end of the support spring is fixedly connected to the lower end face of the support plate to provide support force for the support plate during sliding, ensuring its stable movement. The other end is fixedly connected to the lower end face of the support cavity to absorb the impact force generated during mold closing, thereby effectively reducing the occurrence of flash in the mold. The support plate maintains balance during sliding through these two fixedly connected support springs, and at the moment of mold closing, the support springs can effectively buffer the possible impact, achieving a smooth transition and thus reducing the flash problem caused by impact in the mold.

By rotating the adjusting handle, the first and second slots are moved along the first locking post and the second locking post, thereby adjusting the relative height between the fixed mold core and the moving mold core, and thus adjusting the closing force required for the fixed mold core and the moving mold core to close the mold; The support base is designed with an outer diameter slightly smaller than that of the fixed mold core and the moving mold core, ensuring that it can move smoothly along the support cavity under pressure. It is also stably placed in a specific position of the mold by the support plate, thus providing necessary support during the molding process, preventing the support base from being displaced or damaged due to excessive pressure, and ensuring the quality and precision of the molded parts.

Figure 2 , Figure 3 and Figure 4The quick-release mechanism includes a locking mechanism and a support mechanism. The upper mold base 11 and lower mold base 12 are connected by guide post sleeves 13 at their four corners to ensure the stability and guiding accuracy of the mold base. The upper mold base 21 is fixed to the upper mold base 11 and connected to the fixed mold core 31, realizing a partial structural connection of the upper mold. The lower mold base 22 is fixed to the lower mold base 12 and connected to the moving mold core 32, realizing a partial structural connection of the lower mold. The locking mechanism in the quick-release mechanism allows for fine adjustment of the fixed mold core 31 and the moving mold core 32 to adjust the required mold closing surface pressure, thereby improving the quality consistency of the injection molded products.

[0025] Please refer to details. Figure 3 and Figure 4 The locking mechanism includes a support base 51 fixedly disposed on the fixed mold core 31 and the moving mold core 32 at the ends away from the mold closing surface, a first slot 41 disposed on one side of the outer periphery of the fixed mold core 31 and the moving mold core 32, a second slot 42 disposed on the other side of the outer periphery of the fixed mold core 31 and the moving mold core 32 mirror-image of the first slot 41, a first locking pin 411 slidably connected to the first slot 41, a second locking pin 421 slidably connected to the second slot 42, a fixing support 43 for fixing the first locking pin 411 and the second locking pin 421, and an adjusting handle 7 fixedly disposed on the outer periphery of the moving mold core 32 and the fixed mold core 31. The fixing support 43 is respectively located on the upper mold base 21. The support base 51 is fixedly connected to the lower mold base 22 and is fixedly disposed at the end of the fixed mold core 31 and the moving mold core 32 away from the mold closing surface for support and stability. The first and second locking grooves 42 are respectively disposed on both sides of the outer periphery of the fixed mold core 31 and the moving mold core 32, and are mirror images of each other for sliding of the first locking pin 411 and the second locking pin 421. The first locking pin 411 and the second locking pin 421 are slidably connected to the first locking groove 41 and the second locking groove 42 respectively for adjusting the relative height of the fixed mold core 31 and the moving mold core 32. The fixed support 43 is used to fix and maintain the position of the first locking pin 411 and the second locking pin 421, so as to fix them by adjusting the handle 7. The working principle is: rotating the adjusting handle 7 moves along the first locking pin 411 and the second locking pin 421 through the first locking groove 41 and the second locking groove 42, thereby adjusting the relative height between the fixed mold core 31 and the moving mold core 32, and thus adjusting the closing force required for the fixed mold core 31 and the moving mold core 32 to close the mold.

[0026] Please refer to details. Figure 2 and Figure 4The first and second slots 41 and 42 are respectively configured with open ends at one end and closed ends at the other end. This arrangement facilitates the insertion and removal of the first locking pin 411 and the second locking pin 421. Specifically, the first locking pin 411 and the second locking pin 421 are aligned and moved toward the open ends by the relative rotation of the fixed mold core 31 and the moving mold core 32, thereby allowing them to be easily removed from the first and second slots 41 and 42, achieving the purpose of quickly replacing the fixed mold core 31 and the moving mold core 32. This design simplifies the replacement process and significantly improves operational efficiency. The working principle is to rotate the fixed mold core 31 and the moving mold core 32, causing the first locking pin 411 and the second locking pin 421 to move to the open ends of the first and second slots 41 and 42, thereby achieving quick removal of both and facilitating mold maintenance and replacement.

[0027] Please refer to details. Figure 3 The support assembly includes support cavities respectively disposed on the upper mold base 21 and the lower mold base 22, a telescopic rod 61 disposed in the middle of the support cavity, a support plate 52 connected to the telescopic end of the telescopic rod 61, and a support spring 62 for supporting the support plate 52. The inner wall of the support cavity is tangent to the outer periphery of the support base 51, and the outer diameter of the support base 51 is smaller than the outer diameters of the fixed mold core 31 and the moving mold core 32, respectively. The upper mold base 21 and the lower mold base 22 are respectively provided with support cavities for guiding and supporting the sliding of the support base 51. The shape of the support cavity is consistent with the outer periphery of the support base 51 to ensure that the support base 51 can move smoothly within it. The inner wall of the support cavity is tangent to the outer periphery of the support base 51, allowing the support base 51 to slide freely during mold operation. The telescopic rod 61 disposed in the middle of the support cavity has its telescopic end connected to the support plate 52, which can adjust the position of the support plate 52 as needed. Driven by the telescopic rod 61, the support plate 52 can be adjusted to a higher or lower position to better support the support base 51. Furthermore, a support spring 62 is used to support the support plate 52, ensuring that the support plate 52 remains stably in a suitable equilibrium position and guaranteeing the stability of the support base 51. In this structure, the support base 51, with an outer diameter slightly smaller than that of the fixed mold core 31 and the moving mold core 32, ensures that it can move smoothly along the support cavity under pressure and is stably placed in a specific position in the mold by the support of the support plate 52. This provides necessary support during the molding process, preventing the support base 51 from shifting or being damaged due to excessive pressure, and ensuring the quality and precision of the molded part.

[0028] Please refer to details. Figure 3One end of the support spring 62 is fixedly connected to the lower end face of the support plate 52, and the other end is fixedly connected to the lower end face of the support cavity. The fixed connection of one end of the support spring 62 to the lower end face of the support plate 52 provides support force to the support plate 52 during sliding, ensuring its stable movement. The fixed connection of the other end to the lower end face of the support cavity absorbs the impact force generated during mold closing, thereby effectively reducing the occurrence of flash in the mold. The support plate 52 maintains balance during sliding through these two fixedly connected support springs 62. At the moment of mold closing, the support springs 62 effectively buffer any potential impact, achieving a smooth transition and reducing flash caused by impact in the mold.

[0029] During use, the upper mold base 11 and the lower mold base 12 are connected by guide post sleeves 13 at their four corners to ensure the stability and guiding accuracy of the mold base. The upper mold base 21 is fixed on the upper mold base 11 and connected to the fixed mold core 31, realizing a partial structural connection of the upper mold. The lower mold base 22 is fixed on the lower mold base 12 and connected to the moving mold core 32, realizing a partial structural connection of the lower mold. The adjusting handle 7 moves along the first locking post 411 and the second locking post 421 through the first slot 41 and the second slot 42, thereby adjusting the relative height between the fixed mold core 31 and the moving mold core 32, and thus adjusting the closing force required for the fixed mold core 31 and the moving mold core 32 to close the mold. By rotating the fixed mold core 31 and the moving mold core 32, the first locking post 411 and the second locking post 421 are moved to the open ends of the first slot 41 and the second slot 42, thereby realizing the quick removal of both, which facilitates the maintenance and replacement of the mold.

[0030] In this embodiment, during the process, the support base 51, with an outer diameter slightly smaller than that of the fixed mold core 31 and the moving mold core 32, ensures that it can move smoothly along the support cavity under pressure. Furthermore, it is stably placed at a specific position in the mold by the support plate 52, thus providing necessary support during the molding process. One end of the support spring 62 is fixedly connected to the lower end face of the support plate 52 to provide support force to the support plate 52 during sliding, ensuring its stable movement. The other end is fixedly connected to the lower end face of the support cavity to absorb the impact force generated during mold closing, thereby effectively reducing the occurrence of flash in the mold.

[0031] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
