Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold facilitating demolding. Background Art

[0002] The injection mold is a key process for the production of plastic products. It injects the heated and melted plastic into the mold and forms the required plastic products after cooling. This process is widely used in the manufacture of various plastic products, from small parts such as tableware and electronic accessories to large products such as automotive parts and household appliances.

[0003] However, during the injection molding of transparent accessories, there are certain restrictions on the processing environment. It is necessary to ensure the air quality in the processing space, avoid external dust entering the injection mechanism, and prevent black spots from appearing on the surface of the accessories due to dust adhesion after injection molding, resulting in damage to the accessories. Therefore, it is necessary to set up a protection mechanism to protect the injection mold and ensure the air quality in its processing environment.

[0004] However, the existing protection mechanism simply uses a protection plate and a push-pull door panel to protect and seal the injection mechanism. A sealed box body is formed by combining the protection plate and the door panel, so as to ensure that external dust adheres to the injection mechanism. When demolding, it is necessary to manually slide the door panel to one side to reserve a moving space for taking materials. However, during material taking, the operator's hand will still contact the injection plate, resulting in dust entry, and reciprocally sliding the door panel will also waste processing time.

[0005] Therefore, the utility model proposes an injection mold facilitating demolding. Summary of the Invention

[0006] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose an injection mold facilitating demolding.

[0007] To achieve the above purpose, the utility model adopts the following technical scheme: An injection mold facilitating demolding, comprising a mounting frame, a wind guiding component, and an injection component. The wind guiding component is arranged on the mounting frame. Both sides of the mounting frame are rotatably connected with a first protection plate and a second protection plate. The top and bottom of the mounting frame are provided with wind guiding components between the first protection plate and the second protection plate, and a filtering component is arranged on the top wind guiding component;

[0008] The wind guiding component includes a fan, the fan is connected with the mounting frame, wind guiding seats are arranged on both sides of the fan, the wind guiding seats are connected with the mounting frame, a connecting pipe is fixedly communicated between the wind guiding seats and the fan, and flow dividing plates are arranged at the bottoms of the two wind guiding seats.

[0009] As a preferred embodiment, the fan located at the top rotates clockwise, and the fan located at the bottom rotates counterclockwise.

[0010] The beneficial effect of adopting the above further solution is that when the fan at the top rotates clockwise, during the operation of the fan, under the action of the fan, external air passes through the connecting pipe and the air guide seat, and then under the action of the flow dividing plate, the gas is divided and ejected. When the fan at the bottom rotates counterclockwise, during the operation of the fan, the gas near the flow dividing plate is inhaled into the fan through the air guide seat and the connecting pipe and then discharged.

[0012] The beneficial effect of adopting the above further solution is that the plastic particles are processed by the injection molding assembly. The plastic particles are added into the interior of the delivery pipe through the feed hopper. Under the action of the delivery pipe, the plastic particles are driven to be conveyed to one side. When the plastic particles enter the heater, under the action of the heater, the plastic particles are heated to melt. The melted plastic liquid is injected between the demolding plate and the mold plate, and the mold is cooled by a cooling mechanism. After cooling, the mold plate is displaced by the driving push rod, so that the distance between the demolding plate and the mold plate increases, thereby completing the demolding work.

[0013] As a preferred embodiment, the delivery pipe and the driving push rod are connected to the inner bottom plate of the mounting frame.

[0014] The beneficial effect of adopting the above further solution is that the delivery pipe and the driving push rod are fixed inside the mounting frame by being fixed with bolts.

[0016] The beneficial effect of adopting the above further solution is that the plastic particles are put into the feed hopper through the feed inlet, and the mounting frame is erected at a specified position through the support frame. And multiple groups of support frames are provided, which can effectively increase the stability of the mounting frame during use.

[0017] As a preferred embodiment, the filtering assembly includes a baffle and an air inlet barrel. The baffle is rotatably clamped on the air inlet barrel, a sealing ring is arranged at the connection between the baffle and the air inlet barrel, a filter element is embedded and installed in the air inlet barrel, and an air inlet hole is opened on the air inlet barrel.

[0018] The beneficial effects of adopting the above further solution are as follows: The air inlet holes of the top air guiding component are filtered by the filtering component to prevent the air with impurities from being inhaled by the fan and then ejected through the flow dividing plate. Moreover, the baffle and the air inlet barrel adopt a snap-in installation structure, so it is more convenient and fast to replace the filter element.

[0019] As a preferred embodiment, a sealing ring is arranged at the connection between the baffle and the air inlet barrel.

[0020] The beneficial effects of adopting the above further solution are as follows: The sealing performance at the connection between the baffle and the air inlet barrel is increased through the sealing ring.

[0021] As a preferred embodiment, the air inlet holes are annularly distributed, and the included angles between adjacent two air inlet holes are equal.

[0022] The beneficial effects of adopting the above further solution are as follows: Through multiple groups of annularly arranged air inlet holes, the air near the air inlet barrel can enter the interior of the air inlet barrel through any air inlet hole, and under the action of the air inlet barrel, enter the input end of the fan, so as to ensure the air intake of the fan and prevent the top air guiding component from being unable to form a wind wall due to insufficient air intake.

[0023] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0024] 1. In the present utility model, through the design of the air guiding component, the sliding door panel is replaced to protect the processing space, which can effectively improve the demoulding efficiency. Through the setting of the top fan, the air, under the action of the fan, passes through the connecting pipe and the air guiding seat, and then, under the action of the flow dividing plate, is divided and ejected, so that the air is divided into multiple strands and ejected downward to form an isolation wind wall to prevent dust from entering the processing space. Further, the fan arranged at the bottom sucks the gas ejected near the flow dividing plate, so that the isolation wind wall is in a vertical state, thereby further improving the isolation effect. Moreover, through the design of the wind wall, when the operator takes the material, the dust attached to the hand can be ejected, avoiding bringing dust into the processing space during material taking;

[0025] 2. In the present utility model, the air inlet holes of the top air guiding component are filtered by the filtering component to prevent the air with impurities from being inhaled by the fan and then ejected through the flow dividing plate. Moreover, the baffle and the air inlet barrel adopt a snap-in installation structure, so it is more convenient and fast to replace the filter element. In addition, multiple groups of annularly arranged air inlet holes enable the air near the air inlet barrel to enter the interior of the air inlet barrel through any air inlet hole, and under the action of the air inlet barrel, enter the input end of the fan, so as to ensure the air intake of the fan and prevent the top air guiding component from being unable to form a wind wall due to insufficient air intake.

[0037] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the attached drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0038] Embodiment 1, as Figure 1 - Figure 6As shown in the figure, the utility model provides a technical solution: an injection mold facilitating demolding, which includes a mounting frame 1, an air guiding component 2, and an injection component 4. The air guiding component 2 is arranged on the mounting frame 1. First protective plates 11 and second protective plates 12 are rotatably connected to both sides of the mounting frame 1. Air guiding components 2 are arranged between the first protective plates 11 and the second protective plates 12 at the top and bottom of the mounting frame 1. A filtering component 3 is arranged on the top air guiding component 2;

[0039] The air guiding component 2 includes a fan 21. The fan 21 is connected to the mounting frame 1. Air guiding seats 23 are arranged on both sides of the fan 21. The air guiding seats 23 are connected to the mounting frame 1. A connecting pipe 22 is fixedly communicated between the air guiding seats 23 and the fan 21. Flow dividing plates 24 are arranged at the bottoms of the two air guiding seats 23. Through the design of the air guiding component 2, instead of a sliding door panel, the processing space is protected, which can effectively improve the demolding efficiency. Through the setting of the top fan 21, under the action of the fan 21, air passes through the connecting pipe 22 and the air guiding seats 23 and then, under the action of the flow dividing plate 24, is divided and ejected, so that the air is divided into multiple strands and ejected downward to form an isolation air wall to prevent dust from entering the processing space. Further, the gas ejected near the flow dividing plate 24 is sucked by the fan 21 arranged at the bottom, so that the isolation air wall is in a vertical state.

[0040] The top fan 21 rotates clockwise, and the bottom fan 21 rotates counterclockwise. When the top clockwise rotating fan 21 works, under the action of the fan 21, external air passes through the connecting pipe 22 and the air guiding seats 23 and then, under the action of the flow dividing plate 24, the gas is divided and ejected. When the bottom counterclockwise rotating fan 21 works, the gas near the flow dividing plate 24 is sucked into the fan 21 through the air guiding seats 23 and the connecting pipe 22 and then discharged.

[0041] The injection component 4 includes a conveying pipe 42. A feed hopper 41 is fixedly communicated with the top of the conveying pipe 42. One end of the conveying pipe 42 is fixedly communicated with a heater 43. The other end of the heater 43 is fixedly communicated with a demolding plate 44. A mold plate 45 is arranged on one side of the demolding plate 44. The other end of the mold plate 45 is connected with a driving push rod 46. Through the processing of plastic particles by the injection component 4, the plastic particles are added into the interior of the conveying pipe 42 through the feed hopper 41. Under the action of the conveying pipe 42, the plastic particles are driven to be conveyed to one side. When the plastic particles enter the heater 43, under the action of the heater 43, the plastic particles are heated to melt. The melted plastic liquid is injected between the demolding plate 44 and the mold plate 45, and the mold is cooled by a cooling mechanism. After cooling, the mold plate 45 is displaced by the driving push rod 46, so that the distance between the demolding plate 44 and the mold plate 45 is increased, thereby completing the demolding work.

[0042] The conveying pipe 42 and the driving push rod 46 are connected to the inner bottom plate of the mounting frame 1, and the conveying pipe 42 and the driving push rod 46 are fixed inside the mounting frame 1 by a bolt-fixed mounting method.

[0043] The top of the mounting frame 1 is provided with a feed inlet 13, the feed inlet 13 is communicated with the feed hopper 41, the bottom of the mounting frame 1 is provided with a support frame 14, plastic particles are put into the feed hopper 41 through the feed inlet 13, the mounting frame 1 is erected at a designated position through the support frame 14, and multiple groups of support frames 14 are provided, which can effectively increase the stability of the mounting frame 1 during use.

[0044] Embodiment 2, as Figure 3 - Figure 5 shown, the filtering component 3 includes a baffle 31 and an air inlet barrel 34, the baffle 31 is rotationally clamped on the air inlet barrel 34, a filter element 32 is embedded and installed in the air inlet barrel 34, an air inlet hole 35 is opened on the air inlet barrel 34, and the air inlet hole 35 of the top air guiding component 2 is filtered through the filtering component 3 to prevent the air with impurities from being sucked by the fan 21 and sprayed out through the shunt plate 24. Moreover, the baffle 31 and the air inlet barrel 34 are in a clamped mounting structure, so it is more convenient and fast to replace the filter element 32.

[0045] A sealing ring 33 is arranged at the connection between the baffle 31 and the air inlet barrel 34, and the sealing performance at the connection between the baffle 31 and the air inlet barrel 34 is increased through the sealing ring 33.

[0046] The air inlet holes 35 are annularly distributed, and the included angle between two adjacent air inlet holes 35 is equal. Through the multiple groups of annularly arranged air inlet holes 35, the air near the air inlet barrel 34 can enter the inside of the air inlet barrel 34 through any air inlet hole 35, and enter the input end of the fan 21 under the action of the air inlet barrel 34, thereby ensuring the air intake of the fan 21 and preventing the top air guiding component 2 from being unable to form an air wall due to insufficient air intake.

[0047] As Figures 1-6As shown in the figure, first, the mounting bracket 1 is erected at a designated position through the support bracket 14. Secondly, turn on the two fans 21. Due to the setting of the top fan 21, the air near the air inlet barrel 34 enters the interior of the air inlet barrel 34 through the air inlet holes 35. Under the action of the filter element 32, the air is filtered. The filtered air passes through the connecting pipe 22 and the air guide seat 23 and then, under the action of the flow dividing plate 24, is divided and sprayed out, so that the air is divided into multiple strands and sprayed downward to form an isolation air wall to prevent dust from entering the processing space. Further, the air sprayed out near the flow dividing plate 24 is sucked by the fan 21 arranged at the bottom, so that the isolation air wall is in a vertical state. The plastic particles are put into the feed hopper 41 through the feed port 13 and are driven to be conveyed to one side under the action of the conveying pipe 42. When the plastic particles enter the heater 43, under the action of the heater 43, the plastic particles are heated to make the plastic particles melt. The melted plastic liquid is injected between the demolding plate 44 and the mold plate 45, and the mold is cooled by the cooling mechanism. After cooling, the mold plate 45 is displaced by driving the push rod 46, so that the distance between the demolding plate 44 and the mold plate 45 is increased, thus completing the demolding work.

[0048] The above is only the preferred embodiment of the present invention and is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
