Description

Technical Field

[0001] The utility model relates to the technical field of plastic blister moulds, in particular to a plastic blister mould for thermoplastic forming of a high-precision ABS thick sheet shell. Background Art

[0002] ABS is a common engineering plastic with excellent heat resistance, impact resistance and processing performance. The thick sheet shell refers to a relatively thick external shell structure made of ABS material. The plastic sheet is softened by heating and then vacuum-adsorbed on the mold surface for molding. The softened plastic sheet is moved to the mold by staff.

[0003] A Chinese patent discloses a blister mold for producing ABS shells (authorization announcement number CN214927005U). The patented technology includes: a platform; four vertical rods, which are arranged in a rectangular pattern and fixedly mounted on the top of the platform; a top plate, which is fixedly mounted on the tops of the four vertical rods; a hydraulic push rod, which is fixedly mounted on the bottom of the top plate; a lifting plate, which is slidably mounted on the four vertical rods, and the output rod of the hydraulic push rod is fixedly connected to the top of the lifting plate; a heating mold, which is fixedly mounted on the bottom of the lifting plate; a forming mold, which is fixedly mounted on the top of the platform; an air cavity, which is defined in the forming mold; and a plurality of air holes, each of which is defined on the top inner wall of the air cavity. The blister mold for producing ABS shells provided by this utility model is easy to use and can accelerate the cooling and shaping of the product.

[0004] This patented technology has the advantage of rapid cooling and shaping during use, but it still has some shortcomings during use. The heated and softened plastic sheet is still transported manually. During this process, not only is there a problem of the sheet being deformed and broken due to excessive force during transportation, but it also causes the sheet to be unable to be accurately covered on the mold, resulting in a decrease in the yield rate after the ABS thick sheet shell is blister formed. Therefore, those skilled in the art provide a high-precision ABS thick sheet shell thermoplastic forming blister mold to solve the problems raised in the above background technology.

[0038] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0039] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, three-dimensional dimensions, including length, width, and depth, should be included.

[0041] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0042] Example 1

[0043] See also Figure 1-Figure 5 As shown, this embodiment is a high-precision ABS thick sheet shell thermoplastic forming blister mold, including a bottom plate 100,

[0044] The mold structure 200 includes a mold shell 205, a side plate 202 sleeved on the outside of the mold shell 205, an inner cavity 201 defined within the mold shell 205, a negative pressure port 207 defined within the lower end of the mold shell 205 and extending through the inner cavity 201, and an adsorption hole 206 defined within the mold shell 205.

[0045] The feeding structure 400 includes a mounting frame 401, hydraulic rods 402 fixed to the inside of both sides of the mounting frame 401, a docking frame 403 fixed to the lower end of the hydraulic rods 402, a material trough 405 provided in the upper end of the docking frame 403, hydraulic rods 404 fixed to both sides above the docking frame 403, a mounting frame 407 fixed to the lower end of the hydraulic rods 404, a pressing frame 406 fixed to the lower end of the mounting frame 407, and heating plates 408 evenly spaced at the upper end of the mounting frame 407.

[0046] The inner cavity 201 is provided with a heat exchange tube 204 that passes through the mold shell 205. The middle section of the heat exchange tube 204 is in a spiral shape and fits against the inner wall of the upper end of the mold shell 205.

[0047] Performing the use of the feeding structure 400;

[0048] After the ABS plastic sheet is cut into specified specifications by the cutting shaft, it is placed inside the material trough 405. The second hydraulic rod 404 drives the pressing frame 406 to press the upper side of the ABS plastic sheet. At this time, the heating plate 408 heats the ABS plastic sheet to soften it. The first hydraulic rod 402 drives the docking frame 403 to descend. The docking frame 403 fits with the upper end of the side plate 202, so that the softened ABS plastic sheet contacts the mold and the side plate 202. The negative pressure port 207 is connected to the vacuum pump. The negative pressure is applied to the space between the ABS plastic sheet and the mold shell 205 through the adsorption hole 206, so that the softened ABS plastic sheets fit together and completely fit on the outer wall of the mold shell 205, thus completing the blister processing of the ABS plastic sheet.

[0049] During the cooling and molding process, the heat exchange pipe 204 transports cooling water to cool the mold shell 205, reducing the cooling and molding of the softened ABS plastic sheet that is attached to the outer wall of the mold shell 205, realizing the automatic transportation, heating and blister processing of the ABS thick sheet shell, avoiding the deformation, breakage and difficulty in positioning of the heated and softened ABS plastic sheet when handled by the staff, realizing high-precision blister processing of the ABS plastic sheet, and improving the yield rate of the blister ABS thick sheet shell.

[0051] See also Figure 1-Figure 5 As shown, this embodiment is based on embodiment 1 and also includes:

[0052] as well as;

[0053] The auxiliary structure 300 includes a support frame 301 fixed on the bottom plate 100 and electromagnetic guide rails 306 fixed inside the support frame 301 and symmetrically distributed;

[0054] A mounting tube 303 is provided between the electromagnetic guide rails 306. Electromagnetic sliders 305 are provided at both the front and rear ends of the mounting tube 303, and are slidably connected to the outer wall of the electromagnetic guide rail 306. The upper end of the mounting tube 303 is connected to the mounting hose 302, and the lower end of the mounting tube 303 is provided with equidistantly distributed air nozzles 304.

[0055] A second mounting tube 308 is provided between the electromagnetic guide rails 306. Electromagnetic sliders 307 are provided at both ends of the second mounting tube 308, which are slidably connected to the outer wall of the electromagnetic guide rail 306. The upper end of the second mounting tube 308 is connected to the second mounting hose 310, and the lower end of the second mounting tube 308 is provided with evenly spaced atomizing nozzles 309.

[0056] The outer side of the mold shell 205 is sleeved with a side plate 202. The four corners of the side plate 202 are provided with mutually interpenetrating receiving grooves 208 and travel holes 209. The top plate 203 is provided inside the receiving groove 208.

[0057] A guide rod 210 is provided at the lower end of the top plate 203, a support ring 212 is sleeved on the outer wall of the guide rod 210, and a spring 211 sleeved on the outer side of the guide rod 210 is provided between the support ring 212 and the side plate 202;

[0058] Performing the use of auxiliary structure 300;

[0059] After the ABS sheet is formed by vacuum forming, it needs to be cooled. At this time, the side frame is moved out, and the second hose 310 transports cooling water, which is input into the second mounting pipe 308. The second electromagnetic slider 307 slides on the outer wall of the electromagnetic guide rail 306, driving the second mounting pipe 308 to move, and spraying water mist on the cooled ABS thick sheet shell through the atomizing nozzle 309. It is worth noting that the pressure of the water mist is avoided to be too large, which helps the cooling and forming of the ABS thick sheet shell. After cooling, the ABS thick sheet shell and the side plate 202 can be separated from the mold shell 205. At this time, the elastic force of the spring 211 acts on the top plate 203 through the guide rod 210, pushing the ABS thick sheet shell to lift, so that the ABS thick sheet shell is separated from the side plate 202 and the mold shell 205, and helping the blanking of the ABS thick sheet shell;

[0060] After unloading, the hose 302 is connected to the pressure pump. After the gas is pressurized, it is transported to the inside of the installation tube 303 through the hose 302, slides on the outer wall of the electromagnetic guide rail 306 through the electromagnetic slider 305, and then is sprayed on the side panel 202 and the mold shell 205 through the air nozzle 304, blowing away any water mist that may exist and blowing away any remaining solids, ensuring the cleanliness of the mold shell 205 and the side panel 202 during use, and ensuring the effective blister processing of the subsequent ABS thick sheet shell.

[0061] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or indirect connections through an intermediate medium; and they may refer to internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0062] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention.
