Description

Technical Field

[0001] The utility model relates to the technical field of safety helmet production and processing, in particular to a high-efficiency cooling self-demolding safety helmet rapid injection molding device. Background Technique

[0002] A safety helmet refers to a hat that protects the human head from injuries caused by falling objects and other specific factors. A safety helmet consists of a helmet shell, a helmet lining, a chin strap and accessories, etc. During the production and processing of safety helmets, an injection molding device is generally used;

[0003] An injection molding device is a mechanical equipment that injects molten plastic into a mold through a screw or a plunger of an injection system, and forms the required plastic product after cooling and solidification. Injection molding devices are divided into plunger injection molding machines and screw injection molding machines according to the plasticization method, and can also be divided into hydraulic, mechanical and hydraulic-mechanical (linkage) types according to the transmission method of the machine, and are divided into automatic, semi-automatic and manual injection molding machines according to the operation method. The working principle of an injection molding device is similar to that of a syringe used for injection. With the thrust of a screw or a plunger, the molten plastic in a plasticized state is injected into a closed mold cavity, and the product is obtained after solidification and shaping.

[0004] In a conventional injection molding device, a relatively high residual heat still remains after the internal injection molded parts are formed and solidified, which affects the demolding and parting to a certain extent, thereby affecting the finished product quality of the injection molded parts. It is necessary to provide a certain degree of cooling assistance to avoid this problem.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a high-efficiency cooling self-demolding safety helmet rapid injection molding device is proposed. Content of the Utility Model

[0006] The purpose of the utility model is to provide a high-efficiency cooling self-demolding safety helmet rapid injection molding device to solve the problems raised in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A high-efficiency cooling self-demolding safety helmet rapid injection molding device includes a cooling pool and an air-cooling component. A support frame is installed inside the cooling pool, and an injection component is horizontally installed above the support frame. Injection molds are connected and installed at both ends inside the injection component. The air-cooling components are symmetrically installed on both sides of the injection component. The air-cooling component includes a guide rail, an electric slider, a universal adjustment frame and a vortex tube. Electric sliders are symmetrically installed in the middle section of the guide rail, and universal adjustment frames are installed on both the upper and lower sides of the electric slider. Moreover, a vortex tube is connected and installed at one end of the universal adjustment frame away from the electric slider.

[0008] Further, the supporting bracket includes a filter screen plate, lifting sliders and track columns. Lifting sliders are installed on both the left and right sides of the filter screen plate, and track columns are connected to the sides of the lifting sliders away from the filter screen plate.

[0009] Further, the lifting sliders are slidably connected to the track columns, and four groups of lifting sliders are provided on the sides of the filter screen plate in total.

[0010] Further, the filter screen plate is horizontally installed in the center of the cooling pool, and the track columns are vertically and fixedly installed on the inner wall surface of the cooling pool.

[0011] Further, the injection molding assembly includes a stable track, a device seat, a material injection push rod and a material injection interface. Device seats are connected and installed at both the left and right ends of the stable track. A material injection push rod is horizontally installed in the middle of one side of the device seat close to the vertical central axis of the stable track, and a material injection interface is installed in the middle of the side of the stable track away from the material injection push rod.

[0012] Further, the injection molding die is fixedly connected to the end of the material injection push rod away from the device seat, and both sides of the material injection push rod are slidably connected to the stable track.

[0013] Further, the end of the material injection push rod passing through the device seat is in communication with the material injection interface, and the device seat is fixedly installed at the top side of the cooling pool.

[0014] Further, the guide rail is horizontally and fixedly installed between the left and right device seats, and the guide rail is parallel to the stable track.

[0015] The utility model provides an efficient cooling and self-demolding safety helmet rapid injection molding device, which has the following beneficial effects:

[0016] 1. In the utility model, air-cooling components are symmetrically and horizontally installed on both sides of the injection molding die. The vortex tube and the external air pump unit are interconnected by an air delivery hose. When the air pump unit delivers high-pressure air flow into the vortex tube, under the action of the internal structure of the vortex tube, the input air flow generates a vortex under the action of the vortex tube to separate into two cold and hot air flows. The cold air flow is blown to one side direction of the injection molding die at the output end. At this time, the injection molding parts inside will be exposed after the mold is split, so that rapid cooling can be carried out by using cold air. With the operation of the above structure, combined with the horizontal movement of the electric slider on the surface of the guide rail and the structural mobility of the universal adjustment frame, the vortex tube can effectively cool the surface of the injection molding part and the inner surface of the injection molding die by air cooling. At the same time, the blowing of the high-pressure air flow also facilitates the automatic demolding of the injection molding part from the inside of the injection molding die.

[0017] 2. In this utility model, since both sides of the injection mold are slidably connected to the sides of the stable track and are interconnected with one end of the injection pusher, under the operation of the telescopic structure of the injection pusher, it can perform stable horizontal displacement along the surface of the stable track to achieve left and right mold clamping or mold opening, ensuring the stability and accuracy of the structure during docking and the convenience of demolding the injection molded part after mold opening. In addition, a cooling pool is provided directly below the injection assembly. At the same time, a support bracket is arranged inside the cooling pool, and the cooling pool is filled with a coolant. When the injection mold is opened, with the assistance of the cold air flow output of the air cooling assembly, the injection molded part will be quickly air-cooled and blown to demold, and then fall into the cooling pool filled with the coolant for sufficient cooling. Then, under the operation of the lifting slider, the filter screen plate will lift the injection molded part and vertically lift it along the surface of the track column, facilitating the operator to recycle the injection molded part, thereby achieving the effect of fully cooling and cooling down the injection molded part.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following further describes in detail the embodiments of the present utility model in conjunction with the drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0024] As Figures 1 to 4As shown in the figure, an efficient cooling self-demolding safety helmet rapid injection molding device includes a cooling pool 1 and an air cooling component 5. A support bracket 2 is installed inside the cooling pool 1, and an injection molding component 3 is horizontally installed above the support bracket 2. Injection molds 4 are connected and installed at both ends inside the injection molding component 3. The air cooling components 5 are symmetrically installed on both sides of the injection molding component 3. The air cooling component 5 includes a guide rail 501, an electric slider 502, a universal adjustment bracket 503, and a vortex tube 504. Electric sliders 502 are symmetrically installed in the middle section of the guide rail 501, and universal adjustment brackets 503 are installed on both the upper and lower sides of the electric slider 502. One end of the universal adjustment bracket 503 away from the electric slider 502 is connected and installed with a vortex tube 504. The guide rail 501 is horizontally and fixedly installed between the left and right device seats 302, and the guide rail 501 is parallel to the stable track 301. When the air pump unit transports high-pressure air into the vortex tube 504, under the action of the internal structure of the vortex tube 504 at this time, the input air makes the high-speed air generate a vortex through the action of the vortex tube 504 to separate into two cold and hot air streams, so that the cold air stream is blown to one side direction of the injection mold 4 at the output end. At this time, the injection mold 4 after mold splitting will expose the internal injection molded parts, so that rapid cooling can be carried out using cold air.

[0025] As Figures 1 to 4 shown, the support bracket 2 includes a filter screen plate 201, lifting sliders 202, and track columns 203. Lifting sliders 202 are installed on both the left and right sides of the filter screen plate 201, and a track column 203 is connected to the side of the lifting slider 202 away from the filter screen plate 201. The lifting slider 202 is slidably connected to the track column 203, and four groups of lifting sliders 202 are provided on the side of the filter screen plate 201. The filter screen plate 201 is horizontally installed in the center of the cooling pool 1, and the track column 203 is vertically and fixedly installed on the inner wall surface of the cooling pool 1. The injection molding component 3 includes a stable track 301, a device seat 302, a feeding push rod 303, and a feeding interface 304. Device seats 302 are connected and installed at both ends of the stable track 301, and a feeding push rod 303 is horizontally installed in the middle of the side of the device seat 302 close to the vertical central axis of the stable track 301. A feeding interface 304 is installed in the middle of the side of the stable track 301 away from the feeding push rod 303. The injection mold 4 is fixedly connected to one end of the feeding push rod 303 away from the device seat 302, and both sides of the feeding push rod 303 are slidably connected to the stable track 301. One end of the feeding push rod 303 passing through the device seat 302 is in communication with the feeding interface 304, and the device seat 302 is fixedly installed on the top side of the cooling pool 1. Since both sides of the injection mold 4 are slidably connected to the side of the stable track 301 and are connected to one end of the feeding push rod 303 at the same time, under the operation of the telescopic structure of the feeding push rod 303, it can perform stable horizontal displacement along the surface of the stable track 301 to realize left and right mold closing or mold splitting, and the convenience of demolding the injection molded parts after mold splitting.

[0026] In summary, as Figures 1 to 4 shown, for the high-efficiency cooling self-demolding safety helmet rapid injection molding device, during use, first connect the upstream feeding device to the injection interface 304 on one side of the device base 302 through a pipeline. Then, under the operation of the injection push rod 303, the connected injection mold 4 will gradually translate towards the middle of the injection component 3 along the surface of the stable track 301 until the two injection molds 4 are butted, and the molten material is injected into the refrigerator.

[0027] When the injection molded part inside the injection mold 4 is formed, under the re-operation of the injection push rod 303, the butted injection molds 4 on the left and right will gradually separate. At the same time, the air-cooling component 5 will operate synchronously. At this time, under the operation of the electric slider 502, the vortex tube 504 connected through the universal adjustment frame 503 will move horizontally along the surface of the guide rail 501. At the same time, under the structural movement of the universal adjustment frame 503, the output end of the vortex tube 504 will be directed towards the injection mold 4 and the surface of the injection molded part inside. Then, under the operation of the air pump unit connected in advance through a pipeline, the high-pressure air flow will be quickly converted into a cold air flow under the structural characteristics of the vortex tube 504 and blown to the surface of the injection mold 4 and the injection molded part, rapidly cooling it while using the high-pressure air flow to demold the injection molded part.

[0028] The injection molded part separated from the inner surface of the injection mold 4 will directly fall into the cooling pool 1 filled with coolant below for full immersion cooling. Then, under the operation of the lifting slider 202, the filter screen plate 201 will lift the injection molded part along the surface of the track column 203 and take the injection molded part out of the coolant immersion, so that the operator can take out the injection molded part later.

[0029] The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes.
