[0002] With the rapid development of the plastics industry and the continuous improvement of plastics performance, tableware made of plastic has been widely used. Plastic is mainly composed of carbon, oxygen, hydrogen, nitrogen and other organic or inorganic elements. The finished product is solid, and it is a molten liquid during the manufacturing process. Therefore, it can be heated to melt, pressurized to make it flow, and cooled to solidify, and can be formed into tableware of various shapes.

[0003] At present, plastic tableware is mainly made by stamping and hot melting on the stamping plate of the injection molding machine. After the tableware is hot-melt stamped and formed, it needs to be taken out manually. Since the formed tableware will be stuck and adsorbed in the mold groove, and the mold will heat up rapidly during the stamping and hot melting process, the hands are easy to touch the mold in the process of taking out the tableware, resulting in high temperature burns and skin injuries. In view of the shortcomings of the existing technology, we propose a plastic tableware forming machine to solve the above problems. Utility Model Content

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The embodiment of the present application provides a plastic tableware forming machine to solve the problem that after the current plastic tableware is formed by hot melt stamping, the mold will quickly heat up, and when taking out the tableware, the hands are likely to touch the mold, causing high temperature burns to the skin.

[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] The utility model embodiment discloses a plastic tableware forming machine.

[0027] According to the attached Figure 1-4 As shown, a plastic tableware forming machine includes an injection molding machine body 1 and a top plate 2 and a bottom plate 3 arranged inside the injection molding machine body 1, a template 4 is arranged at the bottom of the bottom plate 3, and a lifting component 5 for lifting tableware is arranged at the bottom of the bottom plate 3, and the lifting component 5 includes:

[0028] A movable plate 502 is arranged on the top of the bottom plate 3, and the movable plate 502 is used to lift and lower the tableware;

[0029] The threaded barrel 304 passes through the top of the bottom plate 3 , and the threaded barrel 304 is used to replace multiple sets of movable plates 502 .

[0030] The top of the base plate 3 is provided with a plurality of circular grooves 301 for mounting the template 4. The bottom of the template 4 is fixedly connected with a connecting rod 402 which is inserted into the circular grooves 301. By inserting templates 4 with circular grooves 301 of different sizes into the circular grooves 301, tableware of different sizes can be molded.

[0031] The bottom of the template 4 is provided with a plurality of groups of tapered grooves 401 , and the tapered grooves 401 correspond to the movable plates 502 , and the movable plates 502 are installed inside the tapered grooves 401 .

[0032] The lifting assembly 5 also includes:

[0033] A support plate 303 is disposed inside the bottom plate 3, and a threaded cylinder 304 is fixedly connected to the top of the support plate 303;

[0034] The hydraulic rod 302 is installed between the support plate 303 and the bottom plate 3. The hydraulic rod 302 is used to move the support plate 303. The support plate 303 can be driven to move upward by the hydraulic rod 302. The movement of the support plate 303 can drive the threaded cylinder 304 and the movable plate 502 to move upward. At this time, the movable plate 502 will push the blister-formed tableware upward, and the tableware can be taken out, avoiding the problem that the tableware is inside the conical groove 401 and is easy to burn the skin due to the high temperature of the template 4 after blistering.

[0035] The bottom of the movable plate 502 is fixedly connected with a threaded rod 501 , which is threadedly connected to the inside of the threaded tube 304 . The movable plate 502 can be disassembled and assembled by rotating the threaded rod 501 , so that the movable plate 502 of corresponding shape can be replaced according to different templates 4 .

[0036] A stamped plastic part 201 is disposed at the bottom of the top plate 2 , and the stamped plastic part 201 corresponds to the conical groove 401 up and down.

[0037] A punching table 101 for cutting tableware is arranged inside the injection molding machine body 1 . After the tableware is formed by vacuum forming, it can be taken out and placed on the punching table 101 . The tableware can be trimmed by the punching plate on the top of the punching table 101 .

[0038] When the utility model is in use, the plastic plate is first placed on the top of the template 4, and then the top plate 2 is driven to punch downward. The punching piece 201 at the bottom of the top plate 2 will perform hot-melt molding on the plastic plate. After compression molding, the support plate 303 can be driven to move upward by the hydraulic rod 302. The movement of the support plate 303 can drive the threaded cylinder 304 and the movable plate 502 to move upward. At this time, the movable plate 502 will push the tableware upward, and the tableware can be taken out and placed on the punching table 101. The punching plate on the top of the punching table 101 can trim the tableware, and the production of the tableware can be completed.

[0039] In summary, compared with the prior art, the present invention has the following beneficial effects: by arranging a movable plate 502 on the top of the bottom plate 3 for facilitating replacement of corresponding shapes, the movable plate 502 can be driven by the hydraulic rod 302 inside the bottom plate 3 to push the tableware formed by vacuum forming upward, so as to facilitate taking out the tableware, thereby avoiding the problem that the current tableware is vacuum formed inside the conical groove 401, and the temperature of the template 4 after vacuum forming is high, which may easily burn the skin. At the same time, by arranging a plug-in template 4, it is convenient to replace the compression molded templates 4 of different sizes in time.
