[0008] An installation groove is provided on the base; a connection block slidably connected to the installation groove is provided at the bottom of the locking block; the driving component includes a driving screw rod rotatably connected in the installation groove, and the driving screw rod is threadedly connected to the connection block; a support block is provided at the notch of the installation groove; the outer end of the driving screw rod is rotatably connected to the support block.

[0009] The outer end of the driving lead screw extends out of the support block, and a driving handwheel is provided at one end of the driving lead screw extending out of the support block.

[0010] A gasket for sealing the bottom of the sleeve mold is provided at the bottom of the placement area.

[0011] A buffer pad is provided on the contact surface between the locking block and the sleeve mold.

[0012] The number of the locking mechanisms is three, and the three locking mechanisms are distributed at 120 degrees to each other.

[0013] Adopting the above technical solution, the utility model has the following beneficial effects: The utility model presses the sleeve through a plurality of locking mechanisms evenly distributed in the circumferential direction, which not only simplifies the overall structure of the locking device, reduces the production cost and is convenient for operation, but also can be applicable to the fixation of sleeve molds of different specifications by adjusting the distance between the locking mechanisms, and has stronger applicability.

[0018] (Embodiment 1)

[0019] See Figure 1 , a fixing device for a nozzle brick mold in this embodiment includes a base 1; a placement area 2 for the sleeve mold is provided at the top of the base 1; a plurality of locking mechanisms 3 are evenly distributed along the circumferential direction on the outside of the sleeve placement area 2 on the base 1; after the plurality of locking mechanisms 3 are closed, the sleeve mold is pressed onto the base 1.

[0020] Further, the locking mechanism 3 includes a locking block 3-1; the outer peripheral surface of the sleeve mold is arranged in a conical shape that is smaller at the top and larger at the bottom; the locking block 3-1 is slidably connected to the base 1; the inner side surface of the locking block 3-1 is arranged in a conical shape that matches the outer peripheral surface of the sleeve mold; and a driving assembly 3-2 for driving the locking block 3-1 to approach or move away from the sleeve mold is provided on the base 1. In the present utility model, the locking block 3-1 with a conical design matches the outer peripheral surface of the sleeve mold. Combining the use of the driving assembly 3-2 makes the fixing and releasing of the mold simple and fast, improves work efficiency, and reduces labor costs.

[0021] Further, an installation groove 1-1 is provided on the base 1; a connecting block 3-3 that is slidably connected to the installation groove 1-1 is provided at the bottom of the locking block 3-1; the driving assembly 3-2 includes a driving lead screw 3-2-1 that is rotatably connected in the installation groove 1-1, and the driving lead screw 3-2-1 is threadedly connected to the connecting block 3-3; a support block 3-2-2 is provided at the notch of the installation groove 1-1; and the outer end of the driving lead screw 3-2-1 is rotatably connected to the support block 3-2-2. The locking mechanism 3 of the present utility model forms multi-point uniform pressing through conical contact, which not only increases the contact area between the mold and the base 1, but also realizes a stronger fastening force through the sliding and threaded connection mechanism of the locking block 3-1, ensuring the stability of the mold during the processing. Due to the adjustable design of the locking mechanism 3, this fixing device can adapt to sleeve molds of different sizes and specifications, improving the versatility and flexibility of the equipment, and reducing the adjustment difficulty and time cost when replacing the mold.

[0022] Further, the outer end of the driving lead screw 3-2-1 extends out of the support block 3-2-2, and a driving handwheel 3-2-3 is provided at the end where it extends out of the support block 3-2-2.

[0023] Further, a sealing gasket that seals the bottom of the sleeve mold is provided at the bottom of the placement area 2 to prevent leakage of the filler.

[0024] Further, a buffer pad is provided on the contact surface between the locking block 3-1 and the sleeve mold. The buffer pad on the contact surface between the locking block 3-1 and the sleeve mold reduces the friction and impact generated by direct contact, extends the service life of the mold and the fixing device, and reduces the maintenance cost.

[0025] Further, the number of the locking mechanisms 3 is three, and the three locking mechanisms 3 are distributed at 120-degree intervals. The locking mechanisms 3 being distributed at 120-degree intervals not only ensures uniform force on the mold, but also makes the overall structure more compact and stable, reduces unnecessary material use, and improves the overall performance and economy of the equipment.
