Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically a mold protective cover structure to prevent waste material from splashing. Background Technology

[0002] To prevent injuries such as cuts and burns to operators from waste materials, debris, sparks, and other flying debris generated during mold processing, and to ensure personnel safety, an outer casing is usually installed to shield them. However, the casing can only protect the operator and cannot prevent waste materials from splashing onto equipment and instruments around the mold. This can cause equipment malfunctions or damage due to foreign objects entering the equipment, reducing its service life. At the same time, to facilitate the operator's observation of the mold processing process, the protective cover should ensure that the operator can clearly see the key parts inside the mold and can shut down the equipment in time if the mold malfunctions.

[0003] Chinese patent CN218361640U discloses a stretching die for preventing waste splashing, comprising a support platform and limit adjustment plates. Two sets of limit adjustment plates are embedded in the inner side of the top of the support platform. Four sets of uprights are embedded in the top of the support platform. Lifting plates are installed on the outer sides of the uprights. Mounting frames are installed on the front and back of the lifting plates. A transparent protective cover is installed at the bottom of the mounting frames. A stamping block is embedded in the inner side of the lifting plate. A mounting plate is installed above the stamping block. The top of the support platform has four sets of positioning holes, which are located on the outside of the upright. The inner side of the support platform has a stamping groove. The front and back sides of the inner side of the support platform each have two sets of limiting slide grooves. The front and back sides of the limiting adjustment plate are equipped with limiting sliders, which are located inside the limiting slide grooves. The bottom of the limiting adjustment plate is equipped with a push plate. The left side of the push plate is equipped with two sets of guide rods, which are located inside the support platform. The right side of the push plate is equipped with a bearing, and the right side of the bearing is embedded with an adjustment knob.

[0004] However, the technical solution of this patent has the following problems:

[0005] This patent does not allow for the unfolding and shielding of waste material as it flies out of the mold, nor does it allow for the intermittent cleaning of the unfolded transparent plastic film.

[0006] Therefore, those skilled in the art have provided a mold protective cover structure to prevent waste splashing in order to solve the above problems. Utility Model Content

[0007] The purpose of this invention is to provide a mold protective cover structure to prevent waste material from splashing, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A mold protective cover structure for preventing waste splashing includes a moving mold and a fixed mold, and further includes: an elastic recovery mechanism and a cleaning mechanism. The two elastic recovery mechanisms are respectively installed on the front and rear sides of the fixed mold, and the cleaning mechanism is installed on the upper side of the fixed mold. The elastic recovery mechanism includes: a left fixed seat, a fixed rod, a baffle, a fixed shaft, a rotating cylinder and a planar spiral spring. The two left fixed seats are fixedly installed on the side wall of the fixed mold. The left fixed seat has a first circular opening. The fixed rod is slidably connected to the first circular opening. The baffle is fixedly installed at one end of the fixed rod near the center of the fixed mold. The fixed shaft is fixedly installed between the two baffles. The rotating cylinder is rotatably connected to the middle side of the fixed shaft. One end of the planar spiral spring is fixedly connected to the fixed shaft, and the other end of the planar spiral spring is fixedly connected to the inner side wall of the rotating cylinder.

[0010] Furthermore, a transparent plastic film is wound around the rotating cylinder, and one end of the transparent plastic film is fixedly connected to the rotating cylinder;

[0011] Furthermore, a first limiting screw is threaded onto the left fixed seat, and the end of the first limiting screw near the left fixed seat is in close contact with the fixing rod.

[0012] Furthermore, the elastic recovery mechanism also includes: protective components, with two protective components respectively installed on the front and rear sides of the moving mold;

[0013] Furthermore, the protective assembly includes: a right-side fixed seat, a support bracket, and a second limiting screw. The two right-side fixed seats are fixedly installed on the side wall of the moving mold. A second circular opening is provided on the right-side fixed seat. The support bracket is slidably connected to the second circular opening. The second limiting screw is threadedly connected to the right-side fixed seat. The end of the second limiting screw near the right-side fixed seat is in close contact with the support bracket.

[0014] Furthermore, the support bracket has a strip-shaped slot on its side, and the end of the transparent plastic film away from the rotating cylinder is placed in the strip-shaped slot;

[0015] Furthermore, the protective assembly also includes a clamping assembly, which is mounted on the support bracket. The clamping assembly includes a pressure plate and third limiting screws. The pressure plate is located on the middle side of the support bracket. The pressure plate has a protrusion located in a strip-shaped slot and presses the transparent plastic film into the strip-shaped slot. One end of each of the two third limiting screws is threaded to the pressure plate, and the other end of each third limiting screw is threaded to the support bracket.

[0016] Furthermore, the cleaning mechanism includes: an extension frame, a fixed tube, and nozzles. The extension frame is fixedly installed on the upper side of the fixed mold, the fixed tube is fixedly connected to the extension frame, and multiple nozzles are fixedly installed on the fixed tube, with the end of each nozzle away from the fixed tube facing the transparent plastic film.

[0017] Compared with the prior art, the beneficial effects of this utility model are: 1. When the moving mold moves toward the fixed mold, the planar spiral spring that undergoes elastic deformation returns to its original state, driving the rotating cylinder to rotate. The rotating cylinder rolls the transparent plastic film onto the rotating cylinder. When the moving mold leaves the fixed mold, the molded parts and waste materials between the moving mold and the fixed mold fall down. The movement of the moving mold drives the support bracket of the protective component and the pressure plate of the pressing component to move. The movement of the pressure plate and the support bracket pulls the transparent plastic film out of the rotating cylinder, causing the transparent plastic film to unfold. The transparent plastic film blocks the molded parts and waste materials that fly out of the fixed mold and the moving mold, preventing the molded parts and waste materials from splashing.

[0018] 2. One end of the fixed pipe of the cleaning mechanism is connected to an external air supply device. The external air supply device intermittently supplies gas from the fixed pipe into the nozzle. The nozzle sprays the gas onto the unfolded transparent plastic film, blowing off the waste adhering to the transparent plastic film, which is beneficial for intermittent cleaning of the unfolded transparent plastic film.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] 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.

[0028] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-6 A mold protective cover structure for preventing waste splashing includes a moving mold 1 and a fixed mold 2, and further includes: an elastic recovery mechanism 3 and a cleaning mechanism 4. The two elastic recovery mechanisms 3 are respectively installed on the front and rear sides of the fixed mold 2, and the cleaning mechanism 4 is installed on the upper side of the fixed mold 2. The elastic recovery mechanism 3 includes: a left fixed seat 31, a fixed rod 32, a baffle 33, a fixed shaft 34, a rotating cylinder 35, and a planar spiral spring 36. The two left fixed seats 31 are fixedly installed on the side wall of the fixed mold 2. The left fixed seat 31 has a first circular opening 37. The fixed rod 32 is slidably connected to the first circular opening 37. The baffle 33 is fixedly installed at one end of the fixed rod 32 near the center of the fixed mold 2. The fixed shaft 34 is fixedly installed between the two baffles 33. The rotating cylinder 35 is rotatably connected to the middle side of the fixed shaft 34. One end of the planar spiral spring 36 is fixedly connected to the fixed shaft 34, and the other end of the planar spiral spring 36 is fixedly connected to the inner side wall of the rotating cylinder 35.

[0029] A transparent plastic film 38 is wound around the rotating cylinder 35, and one end of the transparent plastic film 38 is fixedly connected to the rotating cylinder 35.

[0030] A first limiting screw 39 is threaded onto the left fixed seat 31, and the end of the first limiting screw 39 near the left fixed seat 31 is in close contact with the fixing rod 32.

[0031] When installing the equipment, after fixing the left fixed seat 31 to the side wall of the fixed mold 2, insert the fixing rod 32 into the first circular opening 37 of the two left fixed seats 31, move the fixing rod 32 up and down to the appropriate position, and then tighten the first limit screw 39 on the left fixed seat 31 to fix the fixing rod 32.

[0032] The elastic recycling mechanism 3 also includes: protective components, with two protective components respectively installed on the front and rear sides of the moving mold 1.

[0033] The protective assembly includes: a right-side fixed seat 310, a support bracket 311, and a second limiting screw 312. The two right-side fixed seats 310 are fixedly installed on the side wall of the moving mold 1. A second circular opening 313 is provided on the right-side fixed seat 310. The support bracket 311 is slidably connected to the second circular opening 313. The second limiting screw 312 is threadedly connected to the right-side fixed seat 310. The end of the second limiting screw 312 near the right-side fixed seat 310 is tightly attached to the support bracket 311.

[0034] When installing the equipment, after fixing the right-side fixed seat 310 to the side wall of the moving mold 1, insert the support bracket 311 into the second circular opening 313 of the two right-side fixed seats 310, move the support bracket 311 up and down to the appropriate position, and tighten the second limit screw 312 on the right-side fixed seat 310 to fix the support bracket 311.

[0035] The support bracket 311 has a strip-shaped slot 314 on its side, and the end of the transparent plastic film 38 away from the rotating cylinder 35 is placed in the strip-shaped slot 314.

[0036] The protective assembly further includes a clamping assembly, which is mounted on the support bracket 311. The clamping assembly includes a pressure plate 315 and third limiting screws 316. The pressure plate 315 is disposed on the middle side of the support bracket 311. The pressure plate 315 is provided with a protrusion, which is disposed in a strip-shaped slot 314 and presses the transparent plastic film 38 into the strip-shaped slot 314. One end of each of the two third limiting screws 316 is threaded to the pressure plate 315, and the other end of each third limiting screw 316 is threaded to the support bracket 311.

[0037] When installing the equipment, pull the transparent plastic film 38 out of the rotating cylinder 35, causing the rotating cylinder 35 to rotate. The rotation of the rotating cylinder 35 causes the planar spiral spring 36 to undergo elastic deformation. Place the end of the transparent plastic film 38 away from the rotating cylinder 35 into the strip slot 314. Align the protrusion of the pressure plate 315 with the strip slot 314 and press it into the strip slot 314, so that the transparent plastic film 38 is stuck into the strip slot 314. Tighten the third limit screw 316 to fix the pressure plate 315 on the support bracket 311, and the equipment installation is complete.

[0038] When the moving mold 1 moves toward the fixed mold 2, the planar spiral spring 36, which has undergone elastic deformation, returns to its original state, driving the rotating cylinder 35 to rotate. The rotation of the rotating cylinder 35 rolls the transparent plastic film 38 onto the rotating cylinder 35. When the moving mold 1 leaves the fixed mold 2, the molded parts and waste materials between the moving mold 1 and the fixed mold 2 fall down. The movement of the moving mold 1 drives the support bracket 311 of the protective component and the pressure plate 315 of the pressing component to move. The movement of the pressure plate 315 and the support bracket 311 pulls the transparent plastic film 38 out of the rotating cylinder 35, causing the transparent plastic film 38 to unfold. The transparent plastic film 38 blocks the molded parts and waste materials that fly out of the fixed mold 2 and the moving mold 1, preventing the molded parts and waste materials from splashing.

[0039] Example 2: In some embodiments, such as Figures 1-6 In a preferred embodiment of the present invention, the cleaning mechanism 4 includes an extension frame 41, a fixing tube 42, and a nozzle 43. The extension frame 41 is fixedly installed on the upper side of the fixed mold 2, the fixing tube 42 is fixedly connected to the extension frame 41, and a plurality of nozzles 43 are fixedly installed on the fixing tube 42. The end of the nozzle 43 away from the fixing tube 42 is facing the transparent plastic film 38.

[0040] One end of the fixed pipe 42 of the cleaning mechanism 4 is connected to an external air supply device. The external air supply device intermittently supplies gas from the fixed pipe 42 into the nozzle 43. The nozzle 43 sprays the gas onto the unfolded transparent plastic film 38, blowing off the waste adhering to the transparent plastic film 38, which is beneficial for intermittently cleaning the unfolded transparent plastic film 38.

[0041] 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.
