Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, and more specifically, it relates to an injection mold with a multi-cavity component. Background Art

[0002] In the existing technology, due to only one cavity being provided in the traditional injection mold, the injection efficiency is low during the production process. Each injection can only produce one product, which not only prolongs the production cycle, but also cannot meet the high-efficiency production requirements when facing large-scale production demands. This single-cavity design limits the improvement of production capacity and affects the production efficiency and economic benefits of enterprises.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the present utility model provides an injection mold with a multi-mold cavity assembly, having the following beneficial effects:

[0017] 1. The beneficial effect of the injection mechanism is reflected in that through the combination of the upper mold, the runner system, the support pillars, the lower mold, the mold cavity and the bottom mold, efficient and multi-mold cavity injection molding production is realized. The runner system between the upper mold and the lower mold ensures that the molten plastic material can be evenly distributed into each mold cavity, thereby improving the quality and consistency of the injection molded products. The setting of multiple groups of mold cavities greatly improves the production efficiency. Especially when large-scale production is required, the production cycle can be significantly shortened to meet the market demand.

[0018] 2. The beneficial effects of the clamping mechanism are manifested in that through the coordinated action of components such as the clamping rod, clamping groove, clamping sleeve, control sleeve, inclined rod, and clamping block, the rapid installation and disassembly of the upper mold are realized. The cooperation between the clamping rod and the clamping sleeve, as well as the linkage between the control sleeve, inclined rod, and clamping block, ensure the stability during installation and the convenience during disassembly of the upper mold. The cooperation between the threaded barrel and the screw rod, and the meshing between the driven gear and the gear sleeve enable the operator to precisely control the position of the clamping block by rotating the gear sleeve, thereby achieving the rapid clamping and release of the upper mold.

[0019] 3. The beneficial effect of the rapid unlocking of the clamping mechanism is reflected in that by rotating the gear sleeve, the linkage of the driven gear, threaded barrel, and screw rod is driven, causing the control sleeve to move along the screw rod. Furthermore, the inclined rod contacts the clamping block, realizing the oblique sliding of the clamping block, thereby quickly pulling out the clamping rod from the clamping sleeve and completing the rapid disassembly of the upper mold. This design not only improves the operation convenience but also reduces the production preparation time and increases the utilization rate of production equipment, providing strong support for the rapid mold change and high-efficiency production of injection molds.

[0030] Multiple groups of cavities 6 are arranged and distributed on the cavity 6. The fact that there are multiple groups of cavities 6 distributed on the cavity 6 means that the mold is designed as a multi-cavity structure, and each cavity 6 is used to form a product, improving the injection efficiency because multiple products can be produced simultaneously in each injection cycle, thus increasing the output and shortening the production time.

[0031] Multiple groups of clamping mechanisms are arranged and distributed on the connecting plate 1. The arrangement of multiple groups of clamping mechanisms improves the assembly speed and stability of the mold, making the assembly of the mold more flexible and reliable.

[0032] Multiple groups of inclined rods 12 are installed on the control sleeve 11, and multiple groups of clamping blocks 13 are slidably installed between the multiple groups of inclined rods 12.

Through the movement of the control sleeve 11, the multiple sets of inclined rods 12 contact the clamping blocks 13, causing the multiple sets of clamping blocks 13 to slide obliquely along the multiple sets of inclined rods 12, driving the multiple sets of clamping blocks 13 to move out of the relief holes 18. Then, the clamping rod 8 is inserted into the clamping sleeve 10. The gear sleeve 15 is rotated in the reverse direction to drive the multiple sets of slave gears 16 to rotate.

[0039] There are multiple sets of screws 17 rotatably installed on the clamping sleeve 10, and the tops of the multiple sets of screws 17 are threadedly connected to the multiple sets of threaded barrels 14.

[0040] There are multiple sets of slave gears 16 fixedly installed at the bottoms of the multiple sets of threaded barrels 14 and meshing with the gear sleeve 15.

[0041] More specifically, the rotating gear sleeve 15 rotates, and the gear sleeve 15 and multiple groups of slave gears 16 are meshed with each other, so that the multiple groups of slave gears 16 drive the multiple groups of threaded barrels 14 to rotate, and the multiple groups of threaded barrels 14 rotate along the control sleeve 11 and threadedly cooperate with the multiple groups of screw rods 17, thereby driving the control sleeve 11 to move along the screw rods 17, and through the movement of the control sleeve 11, the multiple groups of inclined rods 12 are brought into contact with the clamping blocks 13, so that the multiple groups of clamping blocks 13 slide obliquely along the multiple groups of inclined rods 12, driving the multiple groups of clamping blocks 13 to move out of the clamping grooves 9, and then the clamping rods 8 are pulled out of the clamping sleeve 10, and the upper mold 2 can be quickly disassembled.
