[0034] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0035] In some embodiments, please refer to the accompanying drawings. Figures 1-4 A mold protective cover that is easy to disassemble includes a molding machine body 1, a moving mold 2, a fixed mold 3, a multi-stage folding protective mechanism 4, and an adjustable installation mechanism 5. The fixed mold 3 is fixedly installed on the fixed end on the left side of the molding machine body 1; the moving mold 2 is fixedly installed on the movable end on the right side of the molding machine body 1.

[0036] Both the front and rear outer sides of the moving mold 2 and the fixed mold 3 are equipped with an adjustable mounting mechanism 5 that facilitates the installation and disassembly of the multi-stage folding protective mechanism 4; the adjustable mounting mechanism 5 includes a fixed mold mounting component, a moving mold mounting component, and a drive component 51;

[0037] The fixed mold mounting assembly and the moving mold mounting assembly have the same structure and function, only their installation positions are different;

[0038] Both the fixed mold mounting assembly and the moving mold mounting assembly consist of a movable component 52 and a support rod 53.

[0039] The drive assembly 51 is mounted on the support rod 53 and connected to the movable assembly 52. ​​The movable assembly 52 is symmetrically mounted on the upper and lower sides of the drive assembly 51. The drive assembly 51 is used to control the synchronous movement of the upper and lower sets of movable assemblies 52.

[0040] The support rods 53 of the fixed mold mounting assembly and the moving mold mounting assembly are equipped with a multi-level folding protective mechanism 4 to prevent material from splashing out during the opening and closing stages of the moving mold 2 and the fixed mold 3;

[0041] The multi-level folding protective mechanism 4 includes a support component 41, multiple sets of scissor assemblies, a limiting baffle 44, and a flexible folding curtain 45.

[0042] The support assembly 41 includes a fixed bait plate 411 and a movable bait plate 412. The fixed bait plate 411 is symmetrically fixedly installed on the upper and lower sides of the outer end of the support rod 53 of the fixed mold mounting assembly; the movable bait plate 412 is symmetrically fixedly installed on the upper and lower sides of the outer end of the support rod 53 of the moving mold mounting assembly.

[0043] Both the fixed bait plate 411 and the movable bait plate 412 have a limiting baffle 44 fixedly installed at their inner ends to restrict the movement direction of the scissor assembly;

[0044] The fixed bait plate 411 and the movable bait plate 412 are connected by multiple sets of scissor assemblies; a flexible folding curtain 45 is provided between adjacent scissor assemblies, and adjacent flexible folding curtains 45 are fixedly connected.

[0045] The flexible folding curtain 45 has a crease in the middle, so that the flexible folding curtain 45 can only be folded outwards when folded.

[0046] In this utility model, the operator, based on the height of the moving mold 2 and the fixed mold 3, drives the two sets of movable components 52 on the fixed mold mounting component and the moving mold mounting component to move synchronously towards each other through the drive component 51 until the two sets of movable components 52 on the fixed mold mounting component abut against the upper and lower ends of the fixed mold 3; and the two sets of movable components 52 on the moving mold mounting component abut against the upper and lower ends of the moving mold 2.

[0047] When the material forming operation begins, the working body 1 of the forming machine drives the moving mold 2 to move to the left. During the movement of the moving mold 2, the support rod 53 on the moving mold mounting assembly moves to the left along with the moving mold 2. The support rod 53 then drives the movable bait plate 412 to move to the left. Since the fixed bait plate 411 remains fixed, the movable bait plate 412 pushes multiple sets of scissor assemblies to the left and folds and retracts to the left. The scissor assemblies drive the flexible folding curtain 45 to fold and retract outwards. The material forming operation can then proceed after the moving mold 2 contacts the fixed mold 3.

[0048] When the material is formed and the mold needs to be opened, the molding machine body 1 drives the moving mold 2 to move to the right. During the movement of the moving mold 2, the support rod 53 on the moving mold mounting assembly moves to the right along with the moving mold 2. The support rod 53 then drives the movable bait plate 412 to move to the right. The movable bait plate 412 then pulls multiple sets of scissor assemblies to unfold to the right. The scissor assemblies then drive the flexible folding curtain 45 to unfold to the right, which can prevent the material from splashing out during mold opening, reducing the extra workload of manual cleaning, and does not affect the normal operation of the mold, ensuring smooth material molding production. Through the cooperation of the drive assembly 51 and the movable assembly 52, the device can be adapted to molds of different sizes, further improving the practicality of the device.

[0049] like Figures 1-4 As shown, the drive assembly 51 includes a rotary knob 511 and a bidirectional lead screw 512; the rotary knob 511 is rotatably mounted on the upper end of the support rod 53; the upper end of the bidirectional lead screw 512 is rotatably connected to the upper end of the support rod 53; the lower end of the bidirectional lead screw 512 is rotatably connected to the lower end of the support rod 53; the bidirectional lead screw 512 is connected to the movable assembly 52; the rotary knob 511 is fixedly connected to the bidirectional lead screw 512.

[0050] like Figures 1-4 As shown, the movable component 52 includes a guide rod 521 and a clamping block 522; the guide rod 521 is fixedly installed between the upper and lower ends of the support rod 53; the clamping block 522 is symmetrically arranged on the upper and lower sides of the bidirectional lead screw 512; and the clamping block 522 is threadedly connected to the bidirectional lead screw 512; the clamping block 522 is slidably connected to the guide rod 521.

[0051] A slot 523 is provided at one end of the clamping block 522 that is close to it; an anti-slip pad is provided inside the slot 523;

[0052] like Figures 1-4 As shown, the scissor lift assembly consists of two movable rods 42 that are hinged to each other via a hinge shaft 43; the ends of two adjacent sets of intersecting movable rods 42 are hinged to each other; and the length of the movable rods 42 in the upper and lower sets of the leftmost and rightmost scissor lift assemblies is half the length of the movable rods 42 in the other sets of scissor lift assemblies.

[0053] One end of the flexible folding curtain 45 is rotatably connected to the hinge shaft 43 of a set of scissor assemblies; the other end of the flexible folding curtain 45 is rotatably connected to the hinge shaft 43 of an adjacent scissor assembly.

[0054] The hinge shaft 43 in the leftmost scissor lift assembly is rotatably connected to the fixed bait plate 411;

[0055] The hinge shaft 43 in the rightmost scissor lift assembly is rotatably connected to the movable bait plate 412;

[0056] In this invention, the operator rotates the knob 511 according to the height of the moving mold 2 and the fixed mold 3. Rotating the knob 511 drives the bidirectional lead screw 512 to rotate, causing the upper and lower clamping blocks 522 to move simultaneously along the guide rod 521 in a direction closer to each other, until the slots 523 provided on the two sets of clamping blocks 522 of the fixed mold mounting assembly abut against the upper and lower ends of the fixed mold 3; the slots 523 provided on the two sets of clamping blocks 522 of the moving mold mounting assembly abut against the upper and lower ends of the moving mold 2.

[0057] When the material forming operation begins, the working body 1 of the forming machine drives the moving mold 2 to move to the left. During the movement of the moving mold 2, the support rod 53 on the moving mold mounting assembly moves to the left along with the moving mold 2. The support rod 53 then drives the movable bait plate 412 to move to the left. Since the fixed bait plate 411 remains fixed, during the movement, the movable bait plate 412 pushes the rightmost set of movable rods 42 to the left to fold and retract to the left, and pushes the adjacent set of movable rods 42 to fold and retract to the left together. The two adjacent sets of movable rods 42 then drive the flexible folding curtain 45 to fold and retract outward until the moving mold 2 contacts the fixed mold 3. At this time, all sets of movable rods 42 and the flexible folding curtain 45 are in a retracted state, and then the material forming operation can be carried out.

[0058] When the material is formed and the mold is opened, the molding machine body 1 drives the moving mold 2 to move to the right. During the movement of the moving mold 2, the support rod 53 on the moving mold mounting assembly will move to the right along with the moving mold 2. The support rod 53 will then drive the movable bait plate 412 to move to the right. The movable bait plate 412 will then pull the rightmost set of movable rods 42 to unfold to the right. Subsequently, the rightmost set of movable rods 42 will pull the adjacent set of movable rods 42 to unfold to the right. At this time, the two adjacent sets of movable rods 42 will unfold the folded flexible curtain 45. At this time, the flexible folded curtain 45 can prevent the material from splashing outwards when the mold is opened.

[0059] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
