Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for mold manufacturing, specifically a clamping fixture for casting mold manufacturing. Background Technology

[0002] In industrial production, casting molds are key tools for product molding. They come in various types, including metal molds, wooden molds, foam molds, and resin molds. With the continuous advancement of mold manufacturing technology in China, the industry's requirements for the processing precision, manufacturing efficiency, and ease of subsequent inspection of casting molds are constantly increasing. Whether it's positioning and clamping during mold processing or comprehensive dimensional inspection after manufacturing, specialized clamping devices are essential to ensure operational stability and safety.

[0003] In the prior art, the utility model patent with announcement number CN219704816U discloses a clamping fixture for manufacturing irregular tungsten steel molds. The fixture achieves mold clamping through a structure such as a placement seat, a two-way threaded rod, a support cylinder, a long screw, and a connecting plate. However, it has a significant defect: after clamping and fixing the mold, it is impossible to rotate and adjust the mold. This results in repeated disassembly and reassembly when processing the mold in multiple directions (such as cutting and grinding at different angles), which seriously affects the processing efficiency and the overall use effect of the equipment.

[0004] Furthermore, in the dimensional inspection stage after casting mold manufacturing, the industry currently generally uses methods such as placing the mold on various platforms and conducting comprehensive inspection by manually flipping it or moving it with the help of hoisting equipment. This method is not only cumbersome to operate, but manual flipping also poses safety hazards, and the hoisting equipment has low moving accuracy, making it difficult to ensure the stability and convenience of the inspection process. There is a lack of a dedicated clamping device that can balance clamping stability and adjustment flexibility and adapt to inspection scenarios, thus failing to meet the industry's demand for an integrated auxiliary tool for casting mold processing and inspection.

[0005] In summary, given the shortcomings of existing clamping fixtures, such as the inability to adjust the mold position in multiple directions and their unsuitability for mold inspection scenarios, there is an urgent need to design a clamping fixture for casting mold manufacturing that can achieve stable mold clamping, flexibly adjust the mold height and angle, and is suitable for mold processing and inspection. This would solve the pain points of existing technologies and improve the efficiency and safety of mold manufacturing and inspection. Utility Model Content

[0006] The purpose of this utility model is to provide a clamping fixture for manufacturing casting molds to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A clamping fixture for manufacturing casting molds includes a base with a fixed seat on it. An adjusting mechanism is provided on the fixed seat, and a stop plate is connected to the adjusting mechanism. The adjusting mechanism is used to adjust the position of the stop plate. The adjusting mechanism includes a lead screw mounted on the fixed seat. The lead screw is threaded through a sliding block and used to push the sliding block up and down. A rotating shaft is rotatably connected to the end of the sliding block away from the fixed seat. A driven gear is fixedly passed through the rotating shaft. The driven gear meshes with a driving gear to drive the rotating shaft to rotate. The driving gear is connected to a motor for driving the driving gear to rotate. A clamping mechanism is provided on the stop plate.

[0009] Preferably, the clamping mechanism is used to clamp the mold.

[0010] Preferably, the clamping mechanism includes a screw mounted on a backing plate, the screw being threaded through a clamping plate for moving the clamping mold, and a second electric motor for driving the screw to rotate is connected to the end of the screw away from the backing plate.

[0011] Preferably, the bottom end of the lead screw is rotatably connected to a fixed base, and the top end of the lead screw is connected to a motor for driving the lead screw to rotate, the motor being mounted on the fixed base.

[0012] Preferably, the sliding block is slidably engaged with the fixed base, and the end of the rotating shaft away from the sliding block is fixedly connected to the abutment.

[0013] Preferably, the motor is mounted on a sliding block on one side of the rotating shaft.

[0014] Preferably, the end of the screw furthest from the motor is rotatably connected to the stop plate.

[0015] Preferably, the clamping mechanism has two sets symmetrically distributed on the abutment plate.

[0016] Preferably, the clamping plate is slidably engaged with the backing plate, and the second motor is located on the side wall of the backing plate.

[0017] Preferably, the opposing surfaces of the two sets of clamps are provided with an anti-slip layer.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. The casting molds in this utility model include: metal molds, wooden molds, foam molds, resin molds, etc. The diversity and complexity of casting molds increase the difficulty of clamping the molds during the mold processing. This utility model moves the mold to be processed between two sets of clamping plates, starts the second motor, drives the screw to rotate, the screw rotates and the screw threadedly connects the clamping plates to move, and the two sets of clamping plates move relative to each other to clamp the mold, which makes it easier to clamp the mold and improves the clamping effect.

[0020] 2. When the mold height needs to be adjusted, the drive motor drives the lead screw to rotate. The lead screw is threadedly connected to the sliding block, which drives the sliding block to rise and fall. The mold moves along with the rotating shaft, the stop plate, and the clamping assembly. When the mold moves to the appropriate height, the motor stops. When the mold angle needs to be adjusted, the drive motor drives the first motor to rotate. The first motor drives the drive gear to rotate. The drive gear meshes with the driven gear, causing the rotating shaft to rotate on the sliding block. The rotation of the rotating shaft causes the stop plate, the clamping assembly, and the mold to rotate along with it, enabling multi-directional adjustment of the mold position and improving the efficiency of the equipment.

[0021] 3. The clamping fixture device for casting mold manufacturing of this utility model is also applicable to the inspection of casting molds. After the casting mold is manufactured, a comprehensive dimensional inspection of the mold is required. Currently, the inspection method mainly involves storing the mold on various platforms and using manual labor or hoisting equipment to flip and move it. There is no simple and convenient clamping device to improve the safety and convenience of the work. The clamping fixture device of this utility model can effectively solve the current problem.

[0029] The adjusting mechanism 3 is used to adjust the position of the abutment 4. The adjusting mechanism 3 includes a lead screw 31 installed on the fixed base 2. The lead screw 31 is threaded through the sliding block 32 and is used to push the sliding block 32 up and down. The end of the sliding block 32 away from the fixed base 2 is rotatably connected to a rotating shaft 33. The rotating shaft 33 is fixedly connected through a driven gear 34.
