Description

Technical Field

[0001] This utility model relates to the field of mold processing technology, and more specifically, to a clamping structure for tightening the edge of an injection mold. Background Technology

[0002] Injection molds are tools used to produce plastic products, giving them a complete structure and precise dimensions. During production, injection molds typically undergo mechanical processing such as cutting and grinding. They often require the use of machining fixtures to fix the semi-finished product onto the machining table, thus facilitating their processing and use.

[0003] Among them, the clamping device for injection mold disclosed in application number CN202222544705.2 is also an increasingly mature technology. By setting up vertical plates and clamping blocks, the position of the external workpiece is automatically and firmly clamped, replacing the previous phenomenon of manually rotating the threaded rod to tighten it, which greatly improves the clamping efficiency of the external workpiece, while also ensuring the clamping tightness.

[0004] Based on this, we agree with the advantages of the aforementioned products, but the following drawbacks still exist:

[0005] This type of clamping device is relatively large, which will occupy a lot of workspace and make it difficult to move, increasing the workload of the staff. Utility Model Content

[0006] The purpose of this invention is to provide a clamping structure for tightening the edges of injection molds, so as to solve the problems mentioned in the background art that occupy a lot of workspace and are difficult to handle.

[0007] This utility model embodiment provides a clamping structure for tightening the edge of an injection mold, including a clamping device;

[0008] The clamping device includes a horizontal plate, a fixed plate at the top center of the horizontal plate, a micro motor vertically mounted at the top of the fixed plate, and a gear at the output end of the micro motor. Both the fixed plate and the horizontal plate have fixed seats at their tops, with crossbars inside. A left sliding block and a right sliding block are slidably mounted on the surfaces of the two sets of crossbars. A long strip is mounted between the left and right sliding blocks. A left connecting block and a right connecting block are mounted at opposite ends of the long strip. A lower rack is mounted on one side of the left connecting block via a pin, and an upper rack is mounted on the side of the right connecting block away from the lower rack via a pin. Matching slots are provided at the positions of the left connecting block and the right connecting block near the upper rack. The gear meshes with and drives the lower and upper racks, which movably pass through the slots of the left and right connecting blocks. Clamping blocks are located at opposite ends of the long strip near the top, and clamping rods are threadedly connected to the tops of the clamping blocks.

[0009] In this embodiment, a micro motor drives the rotation of gears, and the gears mesh to drive the lower rack and upper rack. The lower and upper racks are connected in various ways to make the left and right sliding blocks move closer or further apart, which is convenient for clamping molds of different sizes. The operator can rotate the clamping rod clockwise and counterclockwise to raise and lower the clamping rod to easily clamp or release the mold.

[0010] In one embodiment of this utility model, the top of the fixing plate is provided with an installation groove at the position of the micro motor, and support bars are provided on both sides of the top of the fixing plate outside the lower rack and the upper rack. The top of each set of support bars is rotatably provided with an auxiliary wheel.

[0011] In this design, the mounting slots make the micro motor run more stably, and the support bars are used to connect and support the auxiliary wheels. The auxiliary wheels, located outside the lower and upper racks, can provide additional balance points.

[0012] In one embodiment of this utility model, the horizontal plate is provided with triangular reinforcing blocks on both sides of the fixed plate, and the long strip plate is provided with triangular reinforcing blocks on both sides and the top of the clamping block.

[0013] In this solution, the reinforcement blocks can enhance the connection strength between the horizontal plate and the fixed plate, and the strengthening blocks increase the structural strength of the long strip plate located between the clamping blocks.

[0014] In one embodiment of this utility model, the clamping rod is fitted with a threaded sleeve on the top of the clamping block, and rubber pads are provided at the bottom of the inner end of the clamping block and the bottom end of the clamping rod. The diameters of both ends of the clamping rod are larger than the clamping rod.

[0015] In this design, the clamping rod can be adjusted more precisely using a threaded sleeve, while the rubber pad provides good friction and a comfortable contact surface.

[0016] In one embodiment of this utility model, the horizontal plate is located at the top center of the workbench, the workbench is provided with legs at the four corners of the bottom and a reinforcing rib in the middle, and the bottom of each leg is provided with a caster wheel with a wheel brake.

[0017] In this design, the worktable provides support for the horizontal plate, the outriggers provide height and stability to the worktable, reinforcing ribs increase the structural strength between the outriggers, and casters allow the equipment to be moved flexibly to the required location.

[0018] In one embodiment of this utility model, a switch button is provided at the top of the fixing plate, and the switch button is electrically connected to the micro motor.

[0019] In this solution, the start and stop of the micro motor can be directly controlled by a switch button, saving operators time.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] A micro motor drives the rotation of gears, which mesh to power the lower and upper racks. The lower rack drives the left connecting block and left sliding block to slide along the crossbar. As the left sliding block slides, the long plate and clamping block slide synchronously. The upper rack drives the right connecting block and right sliding block to slide along the crossbar. As the right sliding block slides, the long plate and clamping block slide synchronously. Auxiliary wheels on the outside of the lower and upper racks provide additional balance points, reducing friction and improving the stability of the lower and upper racks. This allows the left and right sliding blocks to move closer or further apart, facilitating the clamping of molds of different sizes. The operator rotates the clamping rod clockwise and counterclockwise to raise and lower it, facilitating the clamping or releasing of the mold. Rubber pads provide good friction and a comfortable contact surface, preventing the clamped mold from slipping. The worktable provides support for the crossbar, and the legs provide height and stability to the worktable. Reinforcing ribs increase the structural strength between the legs, preventing deformation under load. The casters allow the equipment to be moved flexibly to the required position, and the wheel brakes are locked to prevent accidental movement and ensure safety. Attached Figure Description
