Description

Technical Field

[0001] This utility model relates to the technical field of protective devices for injection molds, specifically a protective device for injection molds. Background Technology

[0002] Protective devices for injection molds establish safe operating boundaries through physical isolation and early warning design, preventing injuries to operators.

[0003] For example, a protective device for injection molds, with announcement number "CN213035150U", has vertical plates facing each other, with a collection box and support structure horizontally arranged between the plates. The collection box and support structure are spaced apart along the vertical direction, which can protect against splashed material later, thereby improving the safety of operators, facilitating the later cleaning and recycling of material, and improving production efficiency and resource utilization. However, in the use of the protective device for injection molds, the injection material may be accompanied by high-temperature melt flash with a temperature of 180-220℃ or even higher. The protective cloth has poor high-temperature resistance and may penetrate and leak. At the same time, the cloth is only provided on both sides and there are no other protected areas. The melt flash will directly break out at the unprotected areas, resulting in insufficient protection of the protective device for injection molds and making it easy for operators to be burned. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the protective devices for injection molds are not protective enough and can easily cause burns to operators, and to propose a protective device for injection molds.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a protective device for injection molds, including a base plate and straight plates. The top front and rear sides of the base plate are fixedly connected to the bottom of two straight plates respectively. The outer wall of the straight plates is connected to a protective structure, the inner wall of the straight plates is connected to a fixing structure, and the top of the protective structure is connected to a vertical cylinder.

[0007] Preferably, the protective structure includes a protective cover and a bent rod. The lower outer wall of the protective cover is rotatably connected to the outer wall of the straight plate. The front and rear round openings of the protective cover on the right side are rotatably connected to the inner outer wall of the bent rod, respectively. The front and rear sides of the protective cover on the left side are respectively fixed with grooved plates.

[0008] Preferably, the left side of the outer wall of the bent rod is inserted into the inner wall of the groove plate.

[0009] Preferably, the right slot of the protective cover located on the left side is fixedly connected to the outer wall of the vertical cylinder.

[0010] Preferably, the top of the vertical cylinder is connected to a hopper.

[0011] Preferably, the fixing structure includes a screw and a horizontal plate, the outer wall of the screw is threadedly connected to the inner wall of the horizontal plate, the inner side of the outer wall of the screw is rotatably connected to the outer wall of the horizontal plate, and a handle is fixedly connected to the outer side of the screw.

[0012] Preferably, the bottom of the horizontal plate is attached to the top of the bottom plate.

[0013] The protective device for injection molds proposed in this utility model has the following advantages: by flipping the right-side cover upwards in the protective structure, the outer walls of the two covers come into contact and close. Then, the bent rod rotates to the left, so that the left side of the outer wall of the bent rod is inserted into the inner wall of the groove plate, completing the closure and fixation of the two covers. The covers, made of carbon fiber plate, achieve all-round shielding and protection during injection molding, preventing melt flash from coming into contact with the operator, improving the protective performance of the protective device for injection molds, and preventing the operator from being burned.

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] Please see Figure 1-5 In this embodiment, a protective device for injection molds includes a base plate 1 and a straight plate 4. The top front and rear sides of the base plate 1 are respectively fixed to the bottom of the two straight plates 4. A protective structure 2 is connected to the outer wall of the straight plate 4, a fixing structure 3 is connected to the inner wall of the straight plate 4, and a vertical cylinder 5 is connected to the top of the protective structure 2.

[0022] The protective structure 2 includes a protective cover 201 and a bent rod 202. The lower outer wall of the protective cover 201 is rotatably connected to the outer wall of the straight plate 4. The protective cover 201 rotates under force through the pin in the outer wall of the straight plate 4. The front and rear round openings of the right protective cover 201 are rotatably connected to the inner outer wall of the bent rod 202. The bent rod 202 rotates under force through the bearing in the outer wall of the protective cover 201. The front and rear sides of the left protective cover 201 are fixedly connected to the groove plate 203. The left side of the outer wall of the bent rod 202 is inserted into the inner wall of the groove plate 203. The right groove of the left protective cover 201 is fixedly connected to the outer wall of the vertical cylinder 5. The protective cover 201 is made of carbon fiber plate.

[0023] By flipping the right-side cover 201 upwards through the protective structure 2, the outer walls of the two covers 201 come into contact and close. Then, the bent rod 202 rotates to the left, so that the left side of the outer wall of the bent rod 202 is inserted into the inner wall of the groove plate 203, thus completing the closure and fixation of the two covers 201. The covers 201, through their own carbon fiber plate material, achieve all-round shielding and protection during injection molding, preventing melt flash from coming into contact with the operator, improving the protective performance of the injection mold protection device, and preventing the operator from being burned.

[0024] The top of the vertical cylinder 5 is connected to the hopper 6. The fixed structure 3 includes a screw 301 and a horizontal plate 302. The outer wall of the screw 301 is threadedly connected to the inner wall of the straight plate 4. The screw 301 rotates back and forth through the inner wall of the straight plate 4 under force. The inner side of the outer wall of the screw 301 is rotatably connected to the outer wall of the horizontal plate 302. The inner side of the outer wall of the screw 301 rotates through the bearing in the outer wall of the horizontal plate 302 under force. A handle 303 is fixedly connected to the outer side of the screw 301. The handle 303 facilitates the rotation of the screw 301. The bottom of the horizontal plate 302 is in contact with the top of the bottom plate 1.

[0025] Working principle:

[0026] Protective devices for fixing injection molds:

[0027] Rotate the left side of the outer wall of the bent rod 202 upwards. At this time, the bent rod 202 is disengaged from the groove plate 203. Then pull the bent rod 202 to the right and rotate the right side cover 201 to the right. At this time, the top of the base plate 1 opens. Then place the injection mold on the top of the base plate 1. Check whether the injection mold is located below the vertical cylinder 5. Then adjust the position of the injection mold so that the injection port at the top of the injection mold is located below the vertical cylinder 5. Then rotate the handle 303 with the screw 301 inward through the straight plate 4. The rotating screw 301 moves the horizontal plate 302 inward against the top of the base plate 1, so that the outer wall of the horizontal plate 302 presses against the outer wall of the injection mold to complete the fixation.

[0028] Protective devices for injection molds:

[0029] Flip the right-side cover 201 upwards, at which point the outer walls of the two covers 201 come into contact and close. Then, rotate the bent rod 202 to the left, so that the left side of the outer wall of the bent rod 202 is inserted into the inner wall of the groove plate 203, thus completing the closure and fixation of the two covers 201. The covers 201, through their own carbon fiber plate material, achieve all-round shielding and protection during injection molding, preventing melt flash from coming into contact with the operator.

[0030] Next, the injection material is poured into the hopper 6 and flows downward along the vertical cylinder 5. Then, the injection material enters the top injection port of the injection mold through the bottom of the vertical cylinder 5. The protective cover 201 provides shielding and protection to prevent splashing and burns.

[0031] After completion, the bent rod 202 rotates upward, causing it to detach from the groove plate 203. Then, the protective cover 201 rotates outward through the pin axis on the outer wall of the straight plate 4, completing the separation of the two protective covers 201. Next, the handle 303 rotates outward through the horizontal plate 4 with the screw 301, causing the screw 301 to move outward with the horizontal plate 302, causing the horizontal plate 302 to detach from the outer wall of the injection mold. Then, the injection mold is removed from the top of the base plate 1.

[0032] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
