Description

Technical Field

[0001] This utility model belongs to the field of mechanical design and manufacturing technology, and in particular relates to a mold assembly device for mechanical design and manufacturing. Background Technology

[0002] As the machinery manufacturing industry transforms towards high precision, multi-variety, and fast delivery, mold assembly devices, as core equipment for batch forming of workpieces, directly affect the overall efficiency of the production line and product quality. In mainstream manufacturing fields such as automotive parts, 3C electronic components, and hardware accessories, multi-batch, small-volume order patterns have become the norm. A single production line needs to switch mold specifications multiple times a day, continuously increasing the demand for mold assembly and disassembly efficiency. At the same time, the proportion of complex structural workpieces such as thin-walled parts and irregularly shaped parts is increasing year by year. Traditional demolding methods are prone to workpiece damage, further aggravating production losses.

[0003] Chinese patent application CN222097080U discloses a mold assembly device for mechanical design and manufacturing, including a work plate. Support rods are fixedly installed at the four corners of the top of the work plate. A top plate is fixedly installed at the top of the four support rods. A hydraulic telescopic column is fixedly installed in the middle of the top plate. An upper mold is fixedly installed at the bottom of the hydraulic telescopic column. Extension blocks are fixedly installed on both sides of the upper mold. In this invention, the mold assembly device for mechanical design and manufacturing utilizes a hydraulic telescopic column in the middle of the top plate, an upper mold at the bottom of the hydraulic telescopic column, extension blocks fixedly installed on both sides of the upper mold, extension rods on both sides of each extension block, and a slider fixedly installed at one end of each extension rod. Each slider is slidably mounted on a corresponding support rod, and the upper mold slides up and down via the hydraulic telescopic column.

[0004] Although this patented device uses a hydraulic telescopic column in the middle of the top plate to drive the upper mold to rise and fall, and with the guide structure of extension block, extension rod and slider, to make the upper mold rising and falling process more stable and to accurately control the mold closing height, when facing frequent mold switching under multiple batches of small production, each mold switching requires disassembling and installing bolts one by one, which is cumbersome and time-consuming. In addition, the device is not designed with a special demolding mechanism, and the workpiece needs to be removed manually after pressing. For thin-walled parts and irregular parts, manual removal is prone to deformation or edge breakage due to uneven force.

[0005] To address these issues, we provide a mold assembly device for mechanical design and manufacturing. Utility Model Content

[0006] The purpose of this utility model is to provide a mold assembly device for mechanical design and manufacturing. Through the cooperation of the fixing mechanism and the demolding mechanism, it solves the problems of difficult mold replacement and difficult demolding in the existing mold assembly device for mechanical design and manufacturing.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0008] This utility model relates to a mold assembly device for mechanical design and manufacturing, comprising a worktable, a fixing mechanism at the bottom of the worktable, a lower mold at the bottom of the inner cavity of the worktable, a demolding mechanism at the bottom of the inner cavity of the lower mold, and a pressing mechanism at the top of the inner cavity of the worktable. The fixing mechanism includes a fixing block, one side of which is fixedly connected to the lower mold, and both sides of which are slidably connected to the worktable. A slot is formed at the bottom of the fixing block, and an insert block is slidably connected to the inner cavity of the slot. Both sides of the insert block are slidably connected to the worktable. A lead screw is threadedly connected to one side of the bottom of the insert block, and both ends of the lead screw are rotatably connected to the worktable. A worm gear is fixedly connected to the surface of the lead screw, and a worm is engaged at the bottom of the worm gear. One side of the worm is rotatably connected to the worktable, and the other side of the worm passes through the inner cavity of the worktable and extends to one side of the worktable. There are two lead screws, which are symmetrically distributed on both sides of the bottom of the worktable. This avoids the problem of the insertion block shifting or tilting due to unilateral force when driven by a single lead screw, so that the insertion block can be accurately aligned with the slot at the bottom of the fixing block and inserted smoothly. There are four fixing blocks and four insertion blocks, which are evenly distributed at the four corners of the lower mold. This can evenly transmit the fixing force to the key support position of the lower mold. Support rods are fixedly connected to the four sides of the bottom of the worktable, which can improve the stability of the device during operation.

[0009] The present invention is further configured such that the demolding mechanism includes a motor, one side of which is fixedly connected to the worktable, the output end of which passes through the surface of the worktable and is fixedly connected to a threaded rod, the surface of which is threadedly connected to a load-bearing plate, the other side of which is slidably connected to the worktable, and there are two load-bearing plates, which are symmetrically distributed on both sides of the bottom of the lower mold cavity. Threads are provided on both sides of the surface of the threaded rod, which can drive the two load-bearing plates to open or close synchronously along the bottom of the lower mold cavity.

[0010] The present invention is further configured such that the pressing mechanism includes a hydraulic cylinder, the bottom of the hydraulic cylinder is fixedly connected to the worktable, a push rod is slidably connected to the inner cavity of the hydraulic cylinder, a connecting block is fixedly connected to the bottom of the push rod, an upper mold is detachably connected to the bottom of the connecting block, the top two sides of the upper mold are slidably connected to the worktable, and the connecting block is connected to the upper mold through a lead screw, a fixing block, a slot, and an insert block.

[0011] The present invention is further configured such that a rotating handle is provided on one side of the workbench, and one side of the rotating handle is fixedly connected to a worm gear. The operator can drive the worm gear to operate by simply rotating the rotating handle, thereby realizing the disassembly of the lower mold.

[0012] The present invention is further configured such that a limiting groove is provided in the inner cavity of the workbench, a limiting block is slidably connected to the inner cavity of the limiting groove, and the other side of the limiting block is fixedly connected to the insert block. The setting of the limiting groove and the limiting block can limit the range of motion and operation mode of the insert block.

[0013] The present invention is further configured such that a housing is provided on the surface of the motor, and one side of the housing is fixedly connected to the workbench. The housing can effectively isolate impurities such as dust, oil stains, and metal shavings commonly found in mechanical manufacturing scenarios, and prevent impurities from entering the motor.

[0014] The present invention is further configured such that a sliding groove is provided on one side of the inner cavity of the workbench, and the inner cavity of the sliding groove is slidably connected to the load-bearing plate, and the sliding groove provides precise guidance and limitation for the load-bearing plate.

[0015] The present invention is further configured such that guide rods are fixedly connected to both sides of the top of the upper mold, and the top of the guide rods are slidably connected to the worktable. The guide rods can restrict the movement of the upper mold and improve its stability during operation.

[0016] The present invention has the following beneficial effects.

[0017] 1. This utility model's fixing mechanism significantly improves mold assembly and disassembly efficiency through the transmission and sliding adaptation design of the worm gear and worm wheel, along with the lead screw and insert block. It eliminates the need for tools like wrenches to disassemble bolts one by one; simply rotating the worm gear extending to one side of the worktable drives the lead screw to rotate via the worm wheel, which in turn drives the insert block to slide along the worktable, allowing the insert block to accurately insert into or disengage from the slot at the bottom of the fixing block. The entire disassembly process is completed with a single worm gear operation, completely simplifying the complex process of traditional bolt tightening, effectively shortening the time spent on mold switching, and avoiding efficiency losses caused by excessively long disassembly and assembly operations during production breaks. It perfectly adapts to the production needs of a single production line that frequently switches mold specifications.

[0018] 2. This utility model's demolding mechanism achieves fully automated demolding through motor drive, eliminating the need for direct manual contact or prying of the workpiece. The motor output drives the threaded rod to rotate precisely, and the threaded rod drives the load-bearing plate to slide stably along the worktable through threaded transmission, opening the enclosed space at the bottom of the lower mold. The entire demolding process is precisely controlled by the mechanical structure to apply force, avoiding problems such as excessive local force or deviation in the direction of force when manually removing parts. It can effectively protect the thin sidewalls of thin-walled parts and the irregular protrusions of irregular-shaped parts, significantly reducing the scrap rate during the demolding process and ensuring the quality of product molding.
