[0002] Due to its certain environmental protection performance, and the characteristics of being recyclable and easily degradable after use, pulp molding containers are widely used. When processing pulp molding containers, a pulp molding container mold is used to inject the raw materials of the pulp molding container into the mold, so as to process and form it.

[0003] In the prior art, most of the commonly used pulp molding container molds use heating to accelerate the container forming. After forming, it is necessary to wait for the mold to cool down before injecting slurry again for the next production. The existing pulp molding container molds lack a heat dissipation device, and the cooling time relying on natural heat dissipation is too long, which cannot guarantee the continuity and efficiency of production.

[0004] Therefore, a pulp molding container mold is proposed to solve the above problems. Summary of the Utility Model

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution: a pulp molding container mold, including: an installation base 1, a molding device 2 is arranged at the top end inside the installation base 1, a water cooling device 3 is arranged at the bottom of the installation base 1, and a pressurizing component 4 is arranged on one side of the installation base 1.

[0024] Specifically: The installation base 1 plays a role in supporting and installing. The molding device 2 cooperates with the pressurizing component 4 to produce pulp molding containers, and the water cooling device 3 can accelerate the cooling of the mold cavity 202.

[0025] In one embodiment, a groove 101 is opened at the bottom of the installation base 1.

[0026] Specifically: The groove 101 facilitates the installation of the water cooling device 3.

[0027] In one embodiment, the molding device 2 includes a female mold 201. The bottom side of the top of the female mold 201 is fixedly installed on the top of the installation base 1. The surface of the female mold 201 is fixedly embedded inside the installation base 1. A mold cavity 202 is opened at the top of the female mold 201. A superhydrophobic coating 203 is coated on the inner surface of the mold cavity 202. An installation groove 204 is opened inside the female mold 201, and a track type heating sheet 205 is fixedly installed on the top side inside the installation groove 204.

[0028] Specifically: The superhydrophobic coating 203 facilitates demolding after molding, reduces the pulp residue, the installation groove 204 facilitates the installation of the tracked heating sheet 205. After the cooling pipe 206 is started and powered on through an external controller, it can heat the mold cavity 202.

[0029] In one embodiment, a cooling pipe 206 is embedded inside the bottom side of the mold cavity 202. Both ends of the cooling pipe 206 respectively penetrate and are embedded inside the female mold 201 and the installation base 1. Drainage grooves 207 are respectively formed on both sides of the top of the female mold 201. One ends of the two drainage grooves 207 respectively penetrate through both sides of the top of the mold cavity 202.

[0030] Specifically: Both ends of the cooling pipe 206 are respectively connected to the water supply pipe 304 and the return pipe 305. Driven by the waterproof pump 302, the coolant flows inside the cooling pipe 206 to achieve rapid cooling of the mold cavity 202. After the punch body 403 is pressurized, the excess pulp will be discharged to the outside through the drainage grooves 207 for unified collection.

[0031] In one embodiment, the water cooling device 3 includes a water tank 301. The surface of the water tank 301 is movably embedded inside the groove 101. A waterproof pump 302 is fixedly installed on the bottom side inside the water tank 301. A water inlet pipe 303 is fixedly installed at the water inlet end of the waterproof pump 302. A water supply pipe 304 is fixedly installed at the water outlet end of the waterproof pump 302. A return pipe 305 is installed through one side of the top of the water tank 301. A water inlet is formed through the upper part of one side of the water tank 301, and a water outlet is formed through the lower part of one side of the water tank 301.

[0032] Specifically: An appropriate amount of cooling water is stored inside the water tank 301. After the water tank 301 is started, the waterproof pump 302 sucks the cooling water inside the water tank 301 and then sends it into the cooling pipe 206 through the water supply pipe 304, and finally returns to the water tank 301 through the return pipe 305. The water inlet and the water outlet formed on one side of the water tank are connected to the external water supply and drainage pipelines, and electric control valves are arranged inside both of them to replace the cooling water inside the water tank 301 for cooling.

[0033] In one embodiment, one end of the water supply pipe 304 penetrates through the top of the water tank 301 and is fixedly connected to one end of the cooling pipe 206, and the top end of the return pipe 305 is fixedly connected to the other end of the cooling pipe 206.

[0034] Specifically: When the tracked heating sheet 205 heats the mold cavity 202, the waterproof pump 302 is not started. The residual coolant inside the cooling pipe 206 will flow horizontally and return into the water tank 301 through the water supply pipe 304 and the return pipe 305 to avoid affecting the heating effect.

[0035] In one embodiment, the pressurizing assembly 4 includes an L-shaped support plate 401. One side of the L-shaped support plate 401 is fixedly installed on one side of the mounting base 1. At the bottom of the top end of the L-shaped support plate 401, a hydraulic telescopic rod 402 is fixedly installed. The output end of the hydraulic telescopic rod 402 is fixedly installed with a punch body 403, and a nano-coating 404 is coated on the surface of the punch body 403.

[0036] Specifically: The L-shaped support plate 401 plays a supporting role. After the hydraulic telescopic rod 402 is started, it can drive the punch body 403 to move up and down. The punch body 403 is a common device in the prior art, and its internal structure will not be described in detail. The nano-coating 404 has strong anti-adhesion performance and can also self-repair minor scratches during use, extending the service life of the mold.

[0037] Working principle: When using this device to produce pulp molding containers, first add the pulp molding raw materials into the mold cavity 202 through an external grouting device. Then, start the track-type heating sheet 205 to be powered on and heated through an external controller. Next, start the hydraulic telescopic rod 402 to drive the punch body 403 to descend and squeeze the inside of the mold cavity 202 for pressure forming. After forming, start the hydraulic telescopic rod 402 to reset again and stop heating the track-type heating sheet 205. The super-hydrophobic coating 203 coated on the surface of the mold cavity 202 and the nano-coating 404 coated on the surface of the punch body 403 can reduce pulp residue, reduce the frequency of cleaning and maintenance, and improve the service life of the mold; after forming and demolding, when it is necessary to cool the mold cavity 202, the waterproof pump 302 can be started through an external controller. The waterproof pump 302 extracts the coolant inside the water tank 301 through the water inlet pipe 303 and sends it into the cooling pipe 206 through the water delivery pipe 304, so that the coolant flows rapidly in the cooling pipe 206 and returns to the water tank 301 through the return pipe 305, taking away the heat of the mold cavity 202 to achieve the purpose of rapid cooling, thereby ensuring the continuity and efficiency of production.
