Description

Technical Field

[0001] This utility model relates to the field of grinding technology, and in particular to a high-efficiency grinding machine for precision machining of molds. Background Technology

[0002] Grinding machines are machine tools that use abrasives to grind the surface of workpieces. Most grinding machines use high-speed rotating grinding wheels for grinding, while a few use other abrasives and free abrasives such as oilstones, belt abrasives, honing machines, ultra-precision machining tools, belt grinding machines, grinding machines, and polishing machines.

[0003] Existing high-efficiency grinding machines for mold finishing are not easy to grind multiple parts of the mold, resulting in low grinding efficiency. Furthermore, during mold processing, the grinding accuracy is easily affected by insecure fixing, leading to product scrap. Therefore, a high-efficiency grinding machine for mold finishing is proposed.

[0004] A high-efficiency grinding machine for mold finishing, disclosed in publication number CN215903267U, includes a worktable with a fixed frame on top. The fixed frame is fixedly connected to the worktable. A grinding mechanism is located at the front of the fixed frame, including a control box fixedly connected to it. A connecting shaft is located at the front of the control box, with one end penetrating the control box and rotatably connected to it via a bearing. A grinding wheel support is located at the other end of the connecting shaft and fixedly connected to the connecting shaft. Both ends of the grinding wheel support have drive rollers. This invention utilizes a connecting shaft rotatably connected to the control box. The rotation of the connecting shaft drives the fixedly connected mold support to rotate, causing the abrasive belt between the drive rollers at both ends of the mold support to deflect. This deflected abrasive belt can then process the inclined surface of the mold.

[0005] Although the aforementioned patent achieves the goal of using a connecting shaft that is rotatably connected to the control box, and the rotation of the connecting shaft drives the mold support that is fixedly connected to rotate, causing the sanding belt between the transmission rollers at both ends of the mold support to deflect, so that the deflected sanding belt can process the inclined surface of the mold; however, the device lacks the function of fixing the mold, which can easily cause the mold to tilt during grinding, affecting the grinding accuracy.

[0006] Therefore, it is necessary to invent a high-efficiency machining grinding machine for mold finishing to solve the above problems. Utility Model Content

[0007] The technical problem solved by the utility model is to provide a highly practical and simple-to-operate, high-efficiency grinding machine for mold finishing, which solves the problems of fixing the mold and grinding in multiple positions mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency grinding machine for precision mold machining, comprising a base, a worktable fixedly connected to the top surface of the base, a sliding groove on the surface of the worktable, a placement table slidably connected inside the sliding groove, three sets of fixing mechanisms fixedly connected to the surface of the placement table, each fixing mechanism including a support frame, a threaded rod, a rotating shaft, a fixed plate, a hydraulic rod, and a lower pressure plate, baffles fixedly connected to both sides of the surface of the worktable, a motor housing threadedly connected to the surface of one set of baffles, a drive mechanism fixedly connected inside the motor housing, the drive mechanism including a servo motor and a lead screw, an extension frame fixedly connected to the back of the base, a hydraulic cylinder fixedly connected to the back of the extension frame, a motor box fixedly connected to the end of the hydraulic cylinder, a grinding mechanism fixedly connected inside the motor box, the grinding mechanism including a drive motor and a grinding head.

[0010] As a further embodiment of this utility model, the servo motor is fixedly connected inside the motor housing, and a lead screw is fixedly connected to the output end of the servo motor, so that the servo motor can easily drive the lead screw to rotate.

[0011] As a further embodiment of this utility model, the drive motor is fixedly connected inside the motor box, and a grinding head is fixedly connected to the output end of the drive motor, which facilitates grinding the mold.

[0012] As a further embodiment of this utility model, a bellows is threadedly connected to one side of the base, and a cooling fan is installed inside the bellows to facilitate heat dissipation.

[0013] As a further embodiment of this utility model, a control console is fixedly connected to the upper surface of the base, and four sets of threaded holes are opened on the surface of the base. Four sets of threaded posts are threadedly connected inside the threaded holes, and the threaded posts facilitate the provision of equipment stability.

[0014] As a further embodiment of this utility model, a positioning rod is slidably connected inside the placement platform. The positioning rod is fixedly connected to the surface of the worktable, and the positioning rod facilitates the positioning of the placement platform.

[0015] As a further embodiment of this utility model, the surface of the motor housing is provided with four sets of threaded holes, and bolts are connected to the internal threads of the threaded holes to facilitate the support of the motor housing.

[0016] This utility model provides a high-efficiency machining grinding machine for mold finishing, which has the following beneficial effects:

[0017] 1. This high-efficiency grinding machine for mold finishing, through the setting of drive mechanism, grinding mechanism and hydraulic cylinder, when grinding, the servo motor inside the motor box is started, the servo motor drives the lead screw on one side to rotate, and the placement table connected to the thread on the lead screw moves left and right on the lead screw to increase the horizontal grinding range. Next, the drive motor inside the motor box is started, the drive motor drives the grinding head on one side to grind. With the help of the hydraulic cylinder connected to the back, the vertical range of mold grinding can be increased. The two adjustment structures can be used to grind the mold surface, which significantly improves grinding efficiency and quality.

[0018] 2. This high-efficiency grinding machine for mold finishing uses a fixing mechanism. When fixing the mold, the mold is placed on the placement table, and then the threaded rod on the surface of the support frame is rotated. The threaded rod rotates inside the rotating shaft and drives the fixing plate on the back of the rotating shaft to fix the side of the mold. Next, the hydraulic rod is activated, which drives the lower pressure plate at the end to move until the lower pressure plate firmly fixes the mold from directly above. The use of two sets of fixing structures to fix the mold ensures that the mold will not shift during processing, avoiding the impact of shift on the grinding accuracy. Attached Figure Description
