Description

Technical Field

[0001] The present invention relates to the technical field of safety helmet injection molding, and particularly to an injection molding device for safety helmets that is convenient for cooling. Background Art

[0002] In the production process of safety helmets, injection molding is an essential step. The injection molding of safety helmets requires injecting molten plastic into the safety helmet mold through an injection molding device, and then cooling the injected plastic through the safety helmet mold, so that the plastic solidifies to complete the injection molding of the safety helmet. After the injection molding is completed, the safety helmet needs to be taken out of the injection molding device.

[0003] Since the safety helmet mold is required to cool the molten plastic, during the cooling process, usually only the surface of the safety helmet mold in contact with the molten plastic is cooled. Due to the thickness of the safety helmet mold itself and the cooling efficiency, the entire safety helmet cannot be cooled in a short time. Thus, after the mold is opened, the remaining temperature of the safety helmet mold will conduct heat and cause its temperature to rise. At this time, the surface of the safety helmet mold in contact with the molten plastic exposed to the cold air will quickly form condensed water, which will affect the subsequent injection molding work of the next safety helmet.

[0004] Moreover, the existing safety helmet injection molding usually adopts a direct contact method for collection. In this way, the surface of the safety helmet will be scratched or damaged, making it impossible to recover even with subsequent polishing, resulting in defects. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following advantages: 1. The present invention sprays mist-like coolant onto the outer surfaces of the lower mold and the upper mold through a spraying mechanism, and cooperates with the cooling water pipes inside the lower mold and the upper mold to achieve simultaneous internal and external cooling. Different from the prior art which only cools through the internal cooling water pipes, resulting in poor cooling efficiency. After the lower mold and the upper mold are separated, the temperature of the uncooled position is conducted to the surfaces of the lower mold and the upper mold that are in contact with the finished safety helmet, causing its temperature to rise. At this time, contact with the external cold air will cause condensation water to form on its surface, thus affecting subsequent injection molding.

[0017] 2. The present invention scrapes the residual coolant towards the slot by the inclined edge and collects it, so that the external drainage device can recover the coolant through the opening, which can avoid the problem that after the mist-like coolant cools the outer surfaces of the lower mold and the upper mold, part of the coolant does not evaporate and remains on its surface.

[0018] 3. The present invention inputs dry gas into the second groove through the first connecting pipe and through the air hole by an external drying device. The four second grooves arranged in a plane form a drying area to dry the connection part of the lower mold and the upper mold, thus facilitating the subsequent injection molding work.

[0019] 4. The present invention wipes off the water streaks remaining on the outer surfaces of the lower mold and the upper mold with cotton pads, avoiding the formation of water streaks on the lower mold and the upper mold by the residual coolant scraped by the edge.

[0020] 5. The present invention sprays the coolant in a mist form onto the outer surfaces of the lower mold and the upper mold through several nozzles arranged by the third connecting ring. At the same time, the slider on the first electric slide rail drives the third connecting ring to move up and down, so that the coolant is evenly sprayed onto the outer surfaces of the lower mold and the upper mold. Moreover, the mist-like coolant will be more convenient for absorbing the high temperature on the outer surfaces of the lower mold and the upper mold, improving the cooling efficiency.

Detailed implementation manners

[0023] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with the specific implementation manners and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following descriptions, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0024] Embodiment 1 An injection molding equipment for safety helmets that is convenient for cooling, as Figures 1 - 8 shown, includes a lower workbench 1, an upper workbench 2 and a box body 6; the upper part of the lower workbench 1 is connected with the box body 6; the upper part of the box body 6 is connected with the upper workbench 2; it also includes a spray mechanism 3, a transfer mechanism 4 and a dehumidification mechanism 5; the box body 6 is connected with the spray mechanism 3; the rear part of the box body 6 is connected with the transfer mechanism 4; the outer wall of the box body 6 is connected with the dehumidification mechanism 5; The lower workbench 1 includes a lower mold 101, a first electric push rod 104, and a first housing 105; the upper part of the first housing 105 is connected to a box body 6; the first electric push rod 104 is installed inside the first housing 105; the telescopic end of the first electric push rod 104 is fixedly connected to the lower mold 101, and a first inclined surface 10101 is provided at the upper edge of the lower mold 101. A cooling water pipe is arranged inside the lower mold 101 for cooling the inside of the lower mold 101; the upper workbench 2 includes an upper mold 201, a second electric push rod 204, and a second housing 205; the upper part of the box body 6 is connected to the second housing 205; the second electric push rod 204 is installed inside the second housing 205; the telescopic end of the second electric push rod 204 is fixedly connected to the upper mold 201, and a second inclined surface 20101 is provided at the bottom edge of the upper mold 201. When the lower mold 101 and the upper mold 201 are closed, the first inclined surface 10101 and the second inclined surface 20101 are mutually attached. A cooling water pipe is arranged inside the upper mold 201 for cooling the inside of the upper mold 201.

[0025] A first groove 10102 is provided on the lower mold 101. When the safety helmet finished product 7 is formed by injection molding, due to the existence of the first groove 10102, a thin edge 7001 will be formed on the outer edge of the safety helmet finished product 7, facilitating the transfer mechanism 4 to clamp the safety helmet finished product 7 through the thin edge 7001.

[0026] The lower workbench 1 further includes a first limiting ring 102 and a first connecting ring 103; the first housing 105 is connected to the first connecting ring 103, and the first connecting ring 103 is provided with a connection port for communicating with an external drainage device; the first connecting ring 103 is communicated with the first limiting ring 102, and the inner wall of the first limiting ring 102 is divided into four planes. Each plane is provided with two edges 10201, and the two edges 10201 are inclined towards the middle of the plane. Each plane is provided with a slot 10202 at the middle, and each slot 10202 is provided with an opening 10203 at the bottom.

[0027] The upper workbench 2 further includes a second limiting ring 202 and a first connecting pipe 203; the second housing 205 is connected to the second limiting ring 202. The inner wall of the second limiting ring 202 is divided into four planes. Each plane is provided with a second groove 20201, and each plane is provided with a plurality of air holes 20202; the second limiting ring 202 is communicated with the first connecting pipe 203, and the first connecting pipe 203 passes through the second housing 205 and is used for connecting with an external drying device.

[0028] The upper workbench 2 further includes a cotton sheet 206; the cotton sheet 206 is connected to the bottom of the second limiting ring 202, so that when the lower mold 101 and the upper mold 201 move upward and pass through the cotton sheet 206, the water patterns remaining on the outer surfaces of the lower mold 101 and the upper mold 201 are wiped off.

[0029] The specific working process of the present invention is as follows: First, the lower mold 101 is driven upward by the first electric push rod 104. At the same time, the upper mold 201 is driven downward by the second electric push rod 204 to close the lower mold 101 and the upper mold 201. At this time, the materials required for injection molding are input between the lower mold 101 and the upper mold 201 through an external feeding device. Then, cooling is carried out through the cooling water pipes inside the lower mold 101 and the upper mold 201 to form a safety helmet finished product 7 with the same shape as the gap between the lower mold 101 and the upper mold 201. It should be noted that at this time, the spray mechanism 3 can spray mist-like coolant on the lower mold 101 and the upper mold 201, so as to cool the outer surfaces of the lower mold 101 and the upper mold 201. Cooperating with the cooling water pipes inside the lower mold 101 and the upper mold 201, internal and external cooling is achieved simultaneously, and the lower mold 101 and the upper mold 201 are completely cooled, improving the cooling efficiency of the safety helmet finished product 7. Different from the prior art where only the internal cooling water pipes are used for cooling, after the surfaces of the lower mold 101 and the upper mold 201 in contact with the safety helmet finished product 7 are cooled, due to the relatively thick thickness of the lower mold 101 and the upper mold 201, other positions are not completely cooled. After the lower mold 101 and the upper mold 201 are separated, the temperature of the other uncooled positions is conducted to the surfaces of the lower mold 101 and the upper mold 201 in contact with the safety helmet finished product 7, causing its temperature to rise. At this time, contact with the external cold air will cause condensation water to form on its surface, thus affecting subsequent injection molding.

[0030] Subsequently, when the safety helmet finished product 7 is formed by injection molding, due to the existence of the first groove 10102, a thin edge 7001 will be formed on the outer edge of the safety helmet finished product 7. At this time, the transfer mechanism 4 is used to clamp and transfer the safety helmet finished product 7 for collection. The formation of the thin edge 7001 will make it more convenient for the transfer mechanism 4 to clamp, and the thin edge 7001 can be removed by grinding later, which is different from the problem in the prior art that directly clamping or adsorbing the safety helmet finished product 7 causes scratches or damage to its surface.

[0031] It should be noted that when the mist-like coolant contacts the outer surfaces of the lower mold 101 and the upper mold 201, the evaporation of the coolant will be caused by the high temperature on their surfaces, thus increasing the humidity of the working environment. Therefore, the dehumidification mechanism 5 can continuously dehumidify the working environment to avoid the problem that water patterns or serious water droplets are formed on the inner surfaces of the lower mold 101 and the upper mold 201 due to water vapor, which affects injection molding.

[0032] Furthermore, when the lower mold 101 and the upper mold 201 are closed, the first inclined surface 10101 and the second inclined surface 20101 are mutually attached, so as to prevent the coolant sprayed by the spray mechanism 3 from entering their interiors through the gap at the closed part of the lower mold 101 and the upper mold 201.

[0033] Further, when the lower mold 101 and the upper mold 201 are closed by the above method, and the materials required for injection molding enter the gap between the lower mold 101 and the upper mold 201, and after the spraying mechanism 3 cools their outer surfaces, the lower mold 101 and the upper mold 201 can be driven by the first electric push rod 104 and the second electric push rod 204 to move downward synchronously in a closed state, so that both the lower mold 101 and the upper mold 201 pass through the first limiting ring 102 and then move upward for reset. At this time, the outer surfaces of the lower mold 101 and the upper mold 201 will contact the edge 10201, and the edge 10201 will scrape off the coolant that has not completely evaporated on their surfaces. The inclined edge 10201 will scrape the residual coolant towards the slot 10202 for collection, so that the external drainage device can recover the coolant through the opening 10203. Thus, it can be avoided that after the outer surfaces of the lower mold 101 and the upper mold 201 are cooled by the fog-like coolant, some coolant does not evaporate and remains on their surfaces. When the lower mold 101 and the upper mold 201 are separated, the residual coolant enters the inner surfaces of the lower mold 101 and the upper mold 201, and it will not affect the continuous operation of the internal cooling water pipe.

[0034] Further, after the lower mold 101 and the upper mold 201 both pass through the first limiting ring 102 and move upward for reset, the lower mold 101 and the upper mold 201 can be driven by the first electric push rod 104 and the second electric push rod 204 to move upward synchronously in a closed state until the connection part of the lower mold 101 and the upper mold 201 moves to a horizontal state with the second groove 20201 of the second limiting ring 202, as Figure 6 shown in the state. At this time, the external drying device inputs dry gas into the second groove 20201 through the first connecting pipe 203 and passes through the air hole 20202. The four planar second grooves 20201 will form a drying area, and further dry the connection part of the lower mold 101 and the upper mold 201, so as to facilitate the subsequent injection molding work. At this time, the lower mold 101 and the upper mold 201 can be separated up and down by the first electric push rod 104 and the second electric push rod 204 to obtain the finished safety helmet 7, and then it is transferred and collected by the transfer mechanism 4.

[0035] Further, when the lower mold 101 and the upper mold 201 move upward synchronously, since the cotton sheet 206 is connected to the bottom of the second limiting ring 202, the lower mold 101 and the upper mold 201 can wipe off the water marks remaining on their outer surfaces when passing through the cotton sheet 206, and avoid the residual coolant scraped off by the edge 10201 from forming water marks on the lower mold 101 and the upper mold 201.

[0036] Embodiment 2 On the basis of Embodiment 1, as Figure 7As shown, the spraying mechanism 3 includes a second connecting ring 301, a second connecting pipe 302, a third connecting ring 303, and a first electric slide rail 304; the box body 6 is connected to the second connecting ring 301, and a connection port for connecting an external coolant input device is provided on the second connecting ring 301; one end of a number of second connecting pipes 302 communicates with the second connecting ring 301, and the second connecting pipe 302 is a telescopic hose, and a solenoid valve is provided at the connection between the second connecting ring 301 and the second connecting pipe 302; the other ends of all the second connecting pipes 302 communicate with the third connecting ring 303 together, and a number of nozzles 30301 are provided on the inner surface of the third connecting ring 303; two symmetrically distributed first electric slide rails 304 are jointly installed on the top surface of the first connecting ring 103 and the bottom surface of the second connecting ring 301, and a slider is slidably connected to each first electric slide rail 304, and the third connecting ring 303 is fixedly connected by the two sliders.

[0037] The specific operation of the spraying mechanism 3 of the present invention is as follows: First, the coolant is input into the second connecting ring 301 by an external coolant input device, so that the coolant continuously accumulates inside the second connecting ring 301 until the inside of the second connecting ring 301 is full. Subsequently, the solenoid valve is opened to allow the coolant to enter the inside of the third connecting ring 303 through the second connecting pipe 302, which can avoid the problem of uneven coolant intake of each second connecting pipe 302, and through a number of nozzles 30301 provided on the third connecting ring 303, the coolant is sprayed onto the outer surfaces of the lower mold 101 and the upper mold 201 in a mist form. At the same time, the slider on the first electric slide rail 304 drives the third connecting ring 303 to move up and down, so that the coolant is evenly sprayed onto the outer surfaces of the lower mold 101 and the upper mold 201, and the misty coolant will be more convenient for absorbing the high temperature on the outer surfaces of the lower mold 101 and the upper mold 201, improving the cooling efficiency.

[0038] Embodiment 3 On the basis of Embodiment 2, as Figure 8 shown, the transfer mechanism 4 includes a third housing 401, a second electric slide rail 402, an electric gripper 403, and a collection cylinder 404; the rear part of the box body 6 is connected to the third housing 401; two symmetrically distributed second electric slide rails 402 are installed inside the third housing 401, and a slider is slidably connected to each second electric slide rail 402; the two sliders are jointly fixedly connected to the electric gripper 403, and a clip 40301 for gripping the thin sheet 7001 is provided on the electric gripper 403; the bottom of the third housing 401 is rotationally connected to the collection cylinder 404 by a thread.

[0039] The specific operation of the transfer mechanism 4 of the present invention is as follows: After the current lower mold 101 and upper mold 201 are separated, the lower mold 101 and the upper mold 201 are driven by the first electric push rod 104 and the second electric push rod 204 to move downward synchronously in front of the electric gripper 403. At this time, the electric gripper 403 is driven by the slider on the second electric slide rail 402 to move forward, and the clamping piece 40301 on the electric gripper 403 is controlled to open and close, so as to clamp the finished safety helmet 7. Subsequently, the electric gripper 403 is driven by the slider on the second electric slide rail 402 to move backward above the collection cylinder 404, and the clamping piece 40301 on the electric gripper 403 is controlled to open, so that the finished safety helmet 7 falls into the collection cylinder 404 for collection. Moreover, the collection cylinder 404 is rotationally connected to the third housing 401 by threads, and the operator can remove the collection cylinder 404 at any time to recycle the finished safety helmet 7 inside, improving the practicability.

[0040] Embodiment 4 On the basis of Embodiment 3, as Figure 3 shown, the dehumidification mechanism 5 includes a fourth connecting ring 501 and a third connecting pipe 502; several third connecting pipes 502 are connected to the upper part of the box body 6 in a circumferential distribution; all the third connecting pipes 502 are jointly connected to the fourth connecting ring 501, and a connection port for connecting with an external air extraction device is arranged on the fourth connecting ring 501.

[0041] The box body 6 is provided with a rotating part 6001, and a handle is arranged on the rotating part 6001. The rotating part 6001 is made of a transparent material.

[0042] The working process of the present invention is as follows: The moisture inside the box body 6 is sucked by an external air extraction device through the fourth connecting ring 501 and the third connecting pipe 502. It should be noted that the third connecting pipe 502 is located at the upper part of the box body 6, and the water vapor formed by the evaporation of the coolant will rise and diffuse, so that the circumferentially distributed third connecting pipes 502 can suck the water vapor in the environment faster.

[0043] Furthermore, when the injection molding work is carried out inside the box body 6, it is in a closed state. At this time, the rotating part 6001 made of a transparent material is convenient for the operator to observe the internal injection molding work situation from the outside. After the injection molding is completed, the operator can open it through the handle on the rotating part 6001 to maintain the inside, improving the practicability of the equipment.

[0044] The embodiments of the present invention have been described in detail above with reference to the drawings, but the present invention is not limited to the above embodiments. Various changes can be made without departing from the spirit of the present invention within the knowledge scope of those skilled in the art.
