Description

Technical Field

[0001] The utility model relates to the technical field of plastic sheet extrusion molding manufacturing, in particular to a molding component and cooling molding equipment with the molding component. Background Art

[0002] After the plastic sheet is manufactured by extrusion molding, it is usually at a high temperature, relatively soft in texture, and has an unstable shape. After the extruded plastic sheet is cooled and molded by cooling and molding equipment, the shape of the sheet can be fixed. Existing cooling and molding equipment usually uses a molding component to mold the extruded sheet. The molding component includes a feed port, a molding channel, and a discharge port. The high-temperature plastic sheet extruded by the plastic extruder enters the molding channel through the feed port of the molding component for cooling and molding. The molded sheet is molded and discharged through the discharge port of the molding component. In this process, since the feed port of the molding component is in long-term contact with the high-temperature plastic sheet, it is easy to cause adverse conditions such as sticking, wear, and corrosion at the feed port, which makes the molding ability of the molding component deteriorate and affects the molding effect of the sheet. Existing shaping plates are usually electroplated and sandblasted on their surfaces to form an anti-sticking protective layer. In particular, after the feed port of the shaping plate has been in contact with high-temperature products for a long time, the protective layer will fall off and need to be re-electroplated and sandblasted, which may even cause serious wear and tear on the shaping plate, shortening the service life of the shaping plate.

[0015] According to a preferred embodiment of the utility model, a fluid channel is arranged inside the shaping plate.

[0016] The utility model also provides a cooling and shaping device for plastic extruded sheets, comprising any shaping component described in the above technical solutions.

[0018] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0019] The shaping assembly of the utility model includes two shaping plates, which are sandwiched relative to each other in the up-down direction to form a feed port, a shaping channel and a discharge port which are connected in sequence, and the feed port is detachably provided with anti-sticking parts on at least two upper and lower opposite side walls. Since a detachable anti-sticking part is arranged at the feed port, after the feed port is in contact with the high-temperature sheet product for a long time, since the shaping plate does not directly contact the high-temperature sheet product, the loss problem of the shaping plate can be avoided. The shaping plate equipped with the anti-sticking part can avoid the sticking phenomenon of the feed port. When the anti-sticking part is worn and corroded after being in contact with the high-temperature sheet product for a long time, the service life of the shaping plate can be extended by replacing the anti-sticking part.

[0032] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction on the technical solution of the utility model.

[0033] See also Figure 1 As shown, the utility model provides a cooling and shaping device 100 for plastic extruded sheets, which includes a shaping component 10, a shaping base 20, a lifting component 30 and a cooling component 40.

[0034] Please combine Figure 2 As shown, the shaping assembly 10 includes two shaping plates 101 arranged in the up-down direction, the shaping plate 101 on the lower side is fixedly supported on the shaping base 20, specifically, the shaping plate 101 on the lower side is fixedly supported on the shaping base 20 through a support member 303, and the shaping plate 101 on the upper side is connected through a lifting assembly 30, so that the lifting assembly 30 can drive the shaping plate 101 on the upper side to perform a lifting action, so as to adjust the spacing size of the shaping channel 103 between the two shaping plates 101. The lifting assembly 30 can also drive the shaping plate 101 on the upper side to move up to a position away from the shaping plate 101 on the lower side, thereby opening the shaping channel 103, so that the plastic sheet after cooling and shaping can easily pass through the shaping channel 103, thereby removing the shaped sheet product from the cooling and shaping device 100.

[0035] The lifting assembly 30 includes a lifting cylinder 301 installed on the shaping base 20, a lifting platform 302 located above the shaping assembly 10, and the bottom of the lifting platform 302 is connected to the cylinder shaft of the lifting cylinder 301, so that the lifting platform 302 can be lifted or lowered by the telescopic action of the cylinder shaft of the lifting cylinder 301, thereby realizing the lifting action. The shaping plate 101 located on the upper side is connected to the lifting assembly 30, specifically, the bottom of the lifting platform 302 is connected to the shaping plate 101 on the upper side through a connecting piece 304. When the lifting platform 302 is lifted or lowered, it can drive the shaping plate 101 on the upper side to perform the lifting action together, so as to adjust the spacing of the shaping channel 103 between the shaping plate 101 on the upper side and the shaping plate 101 on the lower side or open the shaping channel 103. Specifically, the spacing between the shaping channels 103 can be adjusted to adapt to the cooling and shaping of plastic high-temperature sheets of different thicknesses. After the shaping channels 103 are opened, the cooled plastic sheets can be quickly discharged, and the formed sheet products can be easily removed.

[0036] In order to facilitate the lifting platform 302 to achieve smooth lifting action, a guide rack 305 is provided on the shaping base 20, and a guide gear 306 is provided on the lifting platform 302. During the lifting action process of the lifting platform 302, the guide gear 306 is always meshed with the guide rack 305 for transmission cooperation.

[0037] In order to facilitate cooling of the shaping component 10 and thus facilitate rapid shaping of the plastic high-temperature sheet, a fluid channel is provided inside the shaping plate 101, and the cooling component 40 is connected to the fluid channel and configured to provide a driving force for the circulation of the cooling fluid in the fluid channel.

[0038] Specifically, the fluid channel includes a water channel 401 arranged inside the shaping plate 101, wherein the water channel 401 is suitable for passing cooling water, and an air channel 402 is also arranged inside the shaping plate 101, and the air channel 402 is suitable for being connected to a negative pressure air source or a negative pressure suction device by airflow, thereby providing a negative pressure suction force for the air channel 402, so that the shaping plate 101 can adsorb the plastic sheet when cooling and shaping the plastic sheet, thereby facilitating the rapid cooling and shaping of the plastic sheet.

[0039] Combination Figure 2 , Figure 3 As shown, two opposite walls of the two shaping plates 101 are provided with a plurality of air grooves 1012 arranged in parallel or in parallel, and these air grooves 1012 are connected to the air channel 402. Due to the provision of these air grooves 402, the plastic high temperature sheet can be adsorbed and shaped in the shaping channel 103, which is convenient for rapid cooling and shaping.

[0040] In some embodiments, other cooling fluid media may also be introduced into the water channel 401, without specific limitation. The cooling assembly 40 may include some cooling fluid medium supply equipment, such as a cooling water tank for supplying cooling water, a cooling water pump, and necessary cooling pipes connected to the water channel 401, etc. The negative pressure air source may include an air pump, a negative pressure gas aspirator, a vacuum compressor, and necessary air pipes connected to the air channel 402, etc., without specific limitation.

[0041] See also Figure 4 , Figure 5 As shown, the shaping assembly 10 includes two shaping plates 101 and two anti-sticking members 105. The two shaping plates 101 are sandwiched relative to each other in the up-down direction to form a feed inlet 102, a shaping channel 103 and a discharge port 104 which are connected in sequence.

[0042] In order to prevent the high temperature plastic sheet from sticking to the feed port 102 of the shaping component 10 , the feed port 102 is detachably provided with anti-sticking members 105 on two upper and lower opposite side walls.

[0043] During operation, the high temperature plastic sheet enters the shaping channel 103 in the shaping component 10 through the feed port 102 for cooling and shaping. The high temperature plastic sheet is not easy to stick at the feed port 102, thus avoiding the sticking phenomenon.

[0044] Since a detachable anti-sticking piece 105 is arranged at the feed port 102, after the feed port 102 is in contact with the high-temperature sheet product for a long time, since the shaping plate 101 is not in direct contact with the high-temperature sheet product, the wear problem of the shaping plate 101 can be avoided. The shaping plate 101 equipped with the anti-sticking piece 105 can not only avoid the sticking phenomenon at the feed port, but also extend the service life of the shaping plate 101 by replacing the anti-sticking piece 105 when the anti-sticking piece 105 is in contact with the high-temperature sheet product for a long time and produces wear, corrosion, etc.

[0045] In some embodiments, the anti-sticking member 105 may cover the outer peripheral surface of the feed port 102, thereby increasing the contact area with the sheet product and improving the anti-sticking ability of the shaping plate 101, without specific limitation.

[0046] Specifically, the anti-adhesive member 105 has an inclined surface 1051 inclined to the horizontal plane. In some embodiments, the shape of the feed port 102 can also be a dovetail shape. This V-shaped or dovetail-shaped feed port 102 can guide the plastic sheet to be cooled and shaped, which is conducive to the plastic sheet entering the shaping channel 103 for cooling and shaping. There is no specific limitation.

[0047] Please combine Figure 3 As shown, a mounting groove 1011 is provided on one side of the shaping plate 101, and the anti-sticking member 105 is in the shape of a plate or a sheet, and the anti-sticking member 105 is installed in the mounting groove 1011. Specifically, screw holes can be punched on the shaping plate 101, and the anti-sticking member 105 can be fixed to the shaping plate 101 by screws. The outer surface of the anti-sticking member 105 after installation is flush with the side wall surface of the shaping plate 101. This arrangement makes the appearance of the shaping plate 101 more neat and the structure more compact. In some embodiments, the connection relationship between the anti-sticking member 105 and the shaping plate 101 can also be a snap connection or a magnetic connection, which is not specifically limited.

[0048] Please combine Figure 5 As shown, an anti-sticking protective layer 1052 is formed on the surface of the anti-sticking member 105. The anti-sticking protective layer 1052 is a tungsten carbide spray layer. The anti-sticking member 105 coated with the tungsten carbide spray layer can not only play an anti-sticking role, but also has the advantages of wear resistance and corrosion resistance, which can increase the service life of the shaping component 10. In some embodiments, the anti-sticking protective layer 1052 can also be a laser hardened layer formed after the surface of the anti-sticking member 105 is treated by laser surface phase change hardening, which is not specifically limited.

[0049] The technical scope of the present invention is not limited to the contents in the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
