Description

Technical Field

[0001] The present application relates to the field of molds, and in particular to a one-time molding mold and system assembly for disposable paper lunch boxes. Background Art

[0002] Disposable paper lunch boxes are a common green and environmentally friendly tableware, wherein the paper lunch box includes a box body and a cover body connected as one body. On the cover body or the box body, at least one component is provided with a plug-in portion, and the other component is provided with a socket. When the box body and the cover body are folded and closed, the plug-in portion is inserted into the socket to close and clamp. In addition, the connecting part of the cover body and the box body of the paper lunch box needs to be pre-pressed to form a bending mark to facilitate the folding of the cover body and the box body.

[0003] A molding mold is required for molding paper lunch boxes. After the disposable paper lunch boxes are molded from paper pulp, two processes are required: pre-pressing to form bending marks and punching to form the sockets. This solution not only requires additional equipment, but also increases the production cost due to the two additional processes. Therefore, it needs to be improved. Summary of the Invention

[0004] In order to improve the above-mentioned problems, the present application provides a disposable paper lunch box one-time molding mold and system assembly.

[0005] The present application provides a disposable paper lunch box one-time forming mold and system assembly adopting the following technical solutions:

[0006] A one-time forming mold for a disposable paper lunch box, comprising an upper mold and a lower mold, wherein the styles of the upper mold and the lower mold are both divided into a cover section, a connecting section and a box section, wherein the connecting section is located between the cover section and the box section and connects the two; the lower mold is provided with a socket forming part and a pre-crease forming part, wherein the socket forming part is located in the cover section and cooperates with the lower mold and the upper mold to form the socket of the paper lunch box; the pre-crease forming part is located in the connecting section and forms a pre-crease when the mold is closed; the upper mold is provided with a pouring port for injecting material, wherein the upper mold and the lower mold are in the closed state to inject material, and the paper lunch box is formed after cooling; the The upper mold is provided with a connecting protrusion for forming a pre-crease, and the lower mold is provided with a pre-crease groove. The pre-crease forming part is located in the pre-crease groove. The connecting protrusion and the pre-crease groove form a wavy spacing space. The pre-crease forming part reduces the distance between the connecting protrusion and the pre-crease groove, so that the wavy spacing space is further reduced. When the wavy spacing space is filled with material to form a wavy connecting part of the paper lunch box, the pre-crease forming part and the connecting protrusion reduce the thickness of the connecting part; the connecting protrusion forms an inner concave of the wavy connecting part, providing a placement space for chopsticks used with the paper lunch box.

[0007] By adopting the above technical solution, when the upper mold and the lower mold are in the mold closing state, the material is injected through the pouring port, and the material fills the filling space between the upper mold and the lower mold. During filling, the material is separated by the socket forming part, and the pre-crease forming part squeezes the material at the connecting section to form a pre-crease. After cooling and demoulding, the upper mold and the lower mold are separated, the material at the cover section is formed into a socket, and a pre-crease is formed at the connecting section. The connecting protrusion and the pre-crease groove form a wavy interval space, so that when forming the paper lunch box, the box cover and the box body can be folded along the wavy connection part, and the pre-crease forming part reduces the distance between the connecting protrusion and the connecting groove, so that the wavy interval space is further reduced and the thickness is reduced. It can make the wavy connection part easier to bend and can be folded at a larger angle to ensure the stability of the connection during use. If the thickness is too large, the same folding angle will easily cause the connection part to break when the box lid and the box body are closed. By reducing the thickness of the bottom, the connection part between the box lid and the box body is more resilient and more resistant to breakage. After the wavy spacing space is filled with material, the wavy connection part corresponding to the connecting protrusion forms an inward concave space. Users can put chopsticks and other tools used with paper lunch boxes into the inward concave space. When the box body and the box lid are folded and tightened against each other, chopsticks and other tools are confined in the inward concave space, which makes it convenient to store chopsticks and other tools while also preventing the loss of chopsticks and other tools.

[0008] Optionally, the upper mold is a smooth casting, and the lower mold is a casting with a dense metal woven mesh laid on the surface.

[0009] By adopting the above technical solution, the casting surface used in the upper mold is smooth, so that when it comes into contact with the material, the surface of the material is a smooth surface, which can correspond to the inner wall of the paper lunch box, making it convenient to hold food. The metal woven mesh of the lower mold can shape the outer wall of the paper lunch box into a metal woven mesh texture when the material is cooled and formed, thereby providing an anti-slip effect. When users use the paper lunch box, they can feel more stable and comfortable.

[0010] Optionally, the crease forming portion includes a semi-arc-shaped forming rod; the forming rod is spaced a preset distance from the groove wall of the pre-crease groove.

[0011] By adopting the above technical solution, the arc-shaped forming rod reduces the distance between the upper mold and the lower mold at the connecting section, and then uses the pre-crease groove to form the crease. At the same time, the preset spacing distance between the connecting groove can further increase the depth of the pre-crease mark during forming, making the box lid and the box body easier to fold, and the arc-shaped style can fit the folding curvature of the box body and the box lid.

[0012] Optionally, a shaping component is further provided in the lower mold, and a circulation pipe for conveying circulating water is externally connected to the shaping component.

[0013] By adopting the above technical solution, the circulating pipe conveys the circulating water to the shaping component, and the shaping component quickly cools the lower mold by water cooling, thereby improving the molding efficiency.

[0014] Optionally, the shaping component includes a water-cooling pipeline, which is divided into two sections, the first section is a pre-creased pipeline, and the second section is a distribution pipeline. The pre-creased pipeline is located in the connecting section, and the distribution pipeline is laid in the cover section and the box section; the inlet of the water-cooling pipeline is located in the pre-creased pipeline, and the outlet is located in the distribution pipeline.

[0015] By adopting the above technical solution, the circulating water will first cool the connecting section and the pre-crease forming part, and then gradually cool the box section and the cover section, so that the material at the connecting section is cooled and solidified, and then the box section and the cover section are cooled, thereby ensuring that the material at the pre-crease can be stably cooled, solidified and formed.

[0016] Optionally, a sliding portion is slidably connected in the pre-creased pipeline, and the sliding portion is provided with a sliding opening; one end of the sliding portion extends toward the distribution pipeline, and when the sliding portion slides along the pre-creased pipeline, the sliding opening gradually connects with the distribution pipeline; the distribution pipeline is provided with a connecting portion, and an elastic portion is provided on the connecting portion, and the elastic portion is connected to the sliding portion and provides elastic force.

[0017] By adopting the above technical solution, when the circulating water enters the pre-crease pipeline, the circulating water will exchange heat with the connecting section of the lower mold and the material in contact with the pre-crease forming part through the pre-crease pipeline. As the water flow continues to enter the pre-crease pipeline, the water pressure in the pre-crease pipeline gradually increases. When the water pressure is greater than the elastic force of the elastic part, the circulating water will push the sliding part to move along the pre-crease pipeline and the connecting part until the sliding port is gradually connected to the distribution pipeline, so that the water flow can be transported to the distribution pipeline, ensuring that the circulating water first cools the pre-crease pipeline and then is transported to the distribution pipeline for cooling.

[0018] Optionally, a vibration component is further provided at the location where the distribution pipeline is connected to the sliding port. The vibration component extends from the distribution pipeline and transmits vibration force to the wall surface of the lower mold through the distribution pipeline.

[0019] By adopting the above technical solution, the vibration component uses the circulating water flowing out of the sliding port to generate driving force to provide vibration, vibrating the uncooled material in the lower mold, so that the material is more evenly distributed in the lower mold through vibration. Therefore, the vibration component extends to the distribution pipeline, so that both the cover section and the box section are covered.

[0020] Optionally, the vibration assembly includes a rotating shaft, a pivot bearing, a rotating blade, a vibrating part and a rebound part; in the distribution pipeline, adjacent pipelines are separated by a vibration cavity; the pivot bearing is installed at the pipe wall of the distribution pipeline; the rotating shaft is pivotally connected to the pivot bearing and extends through the pivot bearing toward the distribution pipeline and the vibration cavity; a number of pivot bearings are arranged along the extension direction of the rotating shaft, and each of the pivot bearings is pivotally connected to the rotating shaft; a rotating blade is provided on the rotating shaft located at the sliding port; a number of vibrating parts are provided, which are distributed on the rotating shaft in the vibration cavity; a number of rebound parts are provided, and are installed in an unfolded manner on the vibrating part, and the rebound part contacts the outer wall of the lower mold.

[0021] By adopting the above technical solution, the circulating water of the sliding port is used to provide the driving force for the rotating blades, so that the rotating shaft rotates along the pivot bearing. During the rotation, the vibration part and the rebound part are driven to rotate in the vibration cavity. The rebound part hits the outer wall of the lower mold to provide vibration force. At the same time, vibration is provided in several vibration cavities to vibrate the material in the lower mold evenly, thereby improving the molding stability of the material.

[0022] A molding system assembly comprises a collector mechanism, an electrical mechanism, an injection molding mechanism, a molding component, a mobile conveying mechanism, a pipeline mechanism, a net washing device, a circulation pipe and the molding mold.

[0023] By adopting the above technical solution, the molding system assembly provides the overall opening and closing of the molding mold, as well as logistics transportation, cooling and shaping, collection and other steps to complete the entire paper lunch box processing flow.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. When the upper mold and the lower mold are in the mold closing state, the material is injected through the pouring port, and the material fills the filling space between the upper mold and the lower mold. During filling, the material is separated by the socket forming part, and the pre-crease forming part squeezes the material at the connecting section to form a pre-crease. After cooling and demoulding, the upper mold and the lower mold are separated, the material at the cover section is formed into a socket, and the connecting section is formed into a pre-crease. The connecting protrusion and the pre-crease groove form a wavy interval space, so that when forming the paper lunch box, the box cover and the box body can be folded along the wavy connection part, and the pre-crease forming part reduces the distance between the connecting protrusion and the connecting groove, so that the wavy interval space is further reduced and the thickness is reduced. The reduced thickness can make the wavy space smaller. The wavy connection part is easier to bend and can be folded at a larger angle to ensure the stability of the connection during use. If the thickness is too large, the connection part will easily break at the same folding angle when the box lid and the box body are closed. By reducing the thickness of the bottom, the connection part between the box lid and the box body is more resilient and more resistant to breakage. After the wavy spacing space is filled with material, the wavy connection part corresponding to the connecting protrusion forms a concave space. Users can put chopsticks and other tools used with paper lunch boxes into the concave space. When the box body and the box lid are folded and tightened, chopsticks and other tools are confined in the concave space, which is convenient for storing chopsticks and other tools while also preventing them from being lost.

[0026] 2. The casting surface of the upper mold is smooth, so that when it comes into contact with the material, the surface of the material is smooth and can correspond to the inner wall of the paper lunch box, making it convenient to hold food. The metal woven mesh of the lower mold can form the outer wall of the paper lunch box into a metal woven mesh texture when the material is cooled and formed, thereby providing an anti-slip effect. When users use the paper lunch box, they can feel more stable and comfortable.

[0027] 3. The arc-shaped forming rod reduces the distance between the upper and lower molds at the connecting section, and then uses the pre-crease groove to form the crease. At the same time, the preset distance between the connecting groove can further increase the depth of the pre-crease during forming, making the box lid and the box body easier to fold. The arc shape can fit the folding curvature of the box body and the box lid. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Throughout this specification, when a device is said to be "connected" to another device, this includes not only "direct connection" but also "indirect connection" with other elements interposed therebetween. Furthermore, when a device is said to "include" a certain component, unless otherwise stated, this does not exclude the inclusion of other components but rather implies that the device may include other components.

[0040] The following is combined with Figure 1 -Attached Figure 6 , further details of this application are given.

[0041] The embodiments of the present application disclose a one-time forming mold and system assembly for a disposable paper lunch box.

[0042] A disposable paper lunch box one-time forming mold, reference Figure 1 and Figure 2 As shown, it includes upper die 1 and lower die 2, refer to Figure 3 and Figure 4 As shown, the styles of the upper mold 1 and the lower mold 2 are divided into a cover section 12, a connecting section 13 and a box body section 14. After the upper mold 1 and the lower mold 2 are closed, the material is filled, and the material in the cover section 12 is formed into the lid of the paper lunch box, and the material in the box body section 14 is formed into the box body of the paper lunch box. The material in the connecting section 13 is formed into a bendable or pivotable connecting portion 33 between the lid and the box body. Therefore, the cover section 12 and the box body section 14 of the upper mold 1 and the lower mold 2 are connected by the connecting section 13, so that the paper lunch box can be completely formed when filling the material.

[0043] refer to Figure 2 or Figure 4 As shown, the lower mold 2 is provided with a socket forming part 21 and a pre-crease forming part 22. After the formed paper lunch box is used to hold food, the lid and the box body need to be folded and closed through the connecting part 33 to prevent food from falling. After closing, the two need to be fixed to prevent the lid from opening. Therefore, the socket forming part 21 is provided. After the upper mold 1 and the lower mold 2 are molded together, the material is filled. Since the socket forming part 21 blocks the material, when demoulding, the part of the paper lunch box separated by the socket forming part 21 forms a socket, and the box body section 14 of the lower mold 2 and the upper mold 1 is provided with a protruding groove for forming a connecting protrusion 15. After the protruding groove is filled with material, a connecting protrusion 15 is formed, and the connecting protrusion 15 is connected to the socket.

[0044] The pre-crease forming portion 22 is located at the connecting section 13 and is used to form a pre-crease for bending the box cover and the box body when the mold is closed and the material is filled.

[0045] The upper mold 1 is provided with a pouring port 11 for injecting material. The number of pouring ports 11 can be set to a certain number. After the mold is closed, the pouring port 11 can be provided to transport and pour the material into the filling space between the upper mold 1 and the lower mold 2.

[0046] Specifically, when the upper mold 1 and the lower mold 2 are in the closed mold state, the material is injected through the pouring gate 11, and the material fills the filling space between the upper mold 1 and the lower mold 2. During filling, the material is separated by the socket forming part 21, and the pre-crease forming part 22 squeezes the material at the connecting section 13 to form a pre-crease. After cooling and demolding, the upper mold 1 is separated from the lower mold 2, the material at the cover section 12 is formed into a socket, and the connecting section 13 is formed into a pre-crease.

[0047] Furthermore, the upper mold 1 is a smooth casting. The surface of the casting used in the upper mold 1 is smooth, so that when it comes into contact with the material, the surface of the material is a smooth surface, which can correspond to the inner wall of the paper lunch box and is convenient for holding food. The lower mold 2 is a casting with a dense metal woven mesh laid on the surface, which corresponds to the outer wall of the molded paper lunch box. When the material is cooled and formed, the metal woven mesh can shape the outer wall of the paper lunch box into a metal woven mesh texture, thereby providing an anti-slip effect. When the user uses the paper lunch box, the contact is more stable and comfortable. The metal woven mesh of the lower mold 2 can be referred to Figure 4 shown.

[0048] In some embodiments, reference Figure 2 As shown, the upper mold 1 is provided with a connecting protrusion 15 for forming a pre-crease, the lower mold 2 is provided with a pre-crease groove 23, the pre-crease forming portion 22 is located in the pre-crease groove 23, the connecting protrusion 15 and the pre-crease groove 23 are both located in the corresponding connecting section 13, and the connecting protrusion 15 and the pre-crease groove 23 form a wavy interval space, so that when the paper lunch box is formed, the wavy interval space is filled with material and forms a wavy connection part at the connection between the box body and the box cover, and the wavy connection part can achieve the effect of pre-bending, so that the box cover and the box body can be bent along the wavy shape. The connecting part is folded, and the pre-crease forming part 22 reduces the distance between the connecting protrusion 15 and the connecting groove, and simultaneously reduces the wavy interval distance, so that the thickness of the wavy connecting part is reduced when the wavy connecting part is formed. The reduced thickness can make the wavy connecting part easier to bend and can be folded at a larger angle, thereby ensuring the stability of the connection during use. If the thickness is too large, the same folding angle will easily cause the connecting part to break when the box cover and the box body are closed. By reducing the thickness of the bottom, the toughness of the connecting part between the box cover and the box body is greater and the fracture resistance is stronger.

[0049] After the wavy spacing space is filled with material, the wavy connection parts corresponding to the connecting protrusions 15 form a concave space. Users can put chopsticks and other tools used with the paper lunch box into the concave space. When the box body and the box lid are folded and tightened against each other, chopsticks and other tools are confined in the concave space, which makes it convenient to store chopsticks and other tools while also preventing them from being lost.

[0050] For further reference, Figure 2 As shown, the pre-crease forming portion 22 includes a semi-arc-shaped forming rod; the forming rod is spaced a preset distance from the groove wall of the pre-crease groove 23, and the semi-arc-shaped forming rod reduces the distance between the upper mold 1 and the lower mold 2 at the connecting section 13, and the distance between the forming rod and the groove wall of the pre-crease groove 23 can further increase the depth of the pre-crease mark, making the box cover and the box body easier to fold, and the arc style can fit the folding curvature of the box body and the box cover.

[0051] In some embodiments, reference Figure 5 As shown, a shaping component 3 is also provided in the lower mold 2. The shaping component 3 is externally connected to a circulation pipe for conveying circulating water. The circulation pipe conveys the circulating water into the shaping component 3. The shaping component 3 is used to quickly cool the lower mold 2 by water cooling, thereby improving the molding efficiency.

[0052] Furthermore, the shaping component 3 includes a water-cooling pipeline 31, which is divided into two sections. The first section is a pre-crease pipeline 311, and the second section is a distribution pipeline 312. The pre-crease pipeline 311 is connected to the connecting section 13. The circulating water of the pre-crease pipeline 311 performs heat exchange on the connecting section 13 in the lower mold 2 and the wall surface of the pre-crease forming part 22, quickly reducing the high temperature of the material, so that the material at the connecting part 33 can be accelerated to solidify, and the distribution pipeline 312 is laid on the cover section 12 and the box section 14 to accelerate the cooling of the materials in the cover section 12 and the box section 14.

[0053] The inlet of the water-cooling pipeline 31 is located in the pre-crease pipeline 311, and the outlet is located in the distribution pipeline 312, so that the circulating water is transported from the pre-crease pipeline 311 to the distribution pipeline 312. The circulating water will first cool the connecting section 13 and the pre-crease forming part 22, and then gradually cool the box body section 14 and the cover body section 12. Since the pre-crease formed by the connecting section 13 is thin, if it is cooled synchronously with other parts, it is easy to cause the pre-crease to break due to thermal expansion and contraction. Therefore, the connecting section 13 and the pre-crease forming part 22 are cooled first. After the material at the connecting section 13 is cooled and solidified, the box body section 14 and the cover body section 12 are cooled, thereby ensuring that the material at the pre-crease can be stably cooled and solidified.

[0054] Further, refer to Figure 6As shown, a sliding portion 32 is slidably connected in the pre-creased pipeline 311. The sliding portion 32 can adopt a sliding column. The sliding portion 32 can block the water flow path of the pre-creased pipeline 311. The sliding portion 32 is provided with a sliding port 321. The sliding port 321 adopts a T-shaped port, that is, it has three water outlet channels. The sliding port 321 is used to provide circulation in the water flow path, and one end of the sliding portion 32 extends toward the distribution pipeline 312. When it slides along the pre-creased pipeline 311, it can extend into the distribution pipeline 312. When the sliding portion 32 slides along the pre-creased pipeline 311, the sliding port 321 gradually communicates with the distribution pipeline 312, thereby gradually opening the water flow path, so that the circulating water can flow into the distribution pipeline 312 through the sliding port 321.

[0055] The distribution pipeline 312 is provided with a connecting part 33, and an elastic part 34 is provided on the connecting part 33. The elastic part 34 is connected to the sliding part 32 and provides elastic force. The connecting part 33 can adopt a connecting ring. The sliding part 32 adopts a sliding column with different diameters at both ends. The diameter close to the connecting ring matches the inner diameter of the connecting ring, and the end away from the connecting ring is located in the pre-creased pipeline 311 and matches the inner diameter of the pre-creased pipeline 311, so that the pre-creased pipeline 311 can be just blocked.

[0056] The elastic part 34 can be a spring, and the elastic part 34 applies an elastic force toward the pre-creased pipeline 311 to the sliding part 32, so that when the sliding part 32 is affected by the water flow, the water pressure will squeeze the elastic part 34, thereby sliding toward the connecting part 33 to gradually open the water flow path between the sliding port 321 and the distribution pipeline 312.

[0057] Specifically, when the circulating water enters the pre-crease pipeline 311, the circulating water exchanges heat with the material in contact with the connecting section 13 of the lower mold 2 and the pre-crease forming part 22 through the pre-crease pipeline 311. As the water flow continues to enter the pre-crease pipeline 311, the water pressure in the pre-crease pipeline 311 gradually increases. When the water pressure is greater than the elastic force of the elastic part 34, the circulating water will push the sliding part 32 to move along the pre-crease pipeline 311 and the connecting part 33 until the sliding port 321 gradually connects with the distribution pipeline 312, so that the water flow can be transported to the distribution pipeline 312, ensuring that the circulating water first cools the pre-crease pipeline 311 and then is transported to the distribution pipeline 312 for cooling.

[0058] In some embodiments, reference Figure 5 and Figure 6 As shown, a vibration component 4 is further provided in the distribution pipeline 312 at the location connected to the sliding port 321. The function of the vibration component 4 is to vibrate the uncooled material in the lower mold 2 so that the material is more evenly distributed in the lower mold 2 through vibration. The vibration component 4 transmits the vibration force to the wall of the lower mold 2 through the distribution pipeline 312, and the driving force for generating the vibration can be the circulating water flowing out of the sliding port 321.

[0059] The vibration component 4 extends to the distribution pipeline 312, so that both the cover section 12 and the box section 14 are covered, and the connecting section 13 has less material and is not suitable for vibration to avoid material breakage. At the same time, the pre-crease pipeline 311 will first cool and solidify the material in the connecting section 13, and then transport circulating water to drive the vibration component 4, so the material in the connecting section 13 will not be affected by vibration.

[0060] For further reference, Figure 6 As shown, the vibration assembly 4 includes a rotating shaft 41, a pivot bearing 42, a rotating blade 43, a vibration part 44 and a rebound part 45; in the distribution pipeline 312, adjacent pipelines are separated by a vibration cavity 24, and the inner wall of the vibration cavity 24 can be directly the outer wall of the lower mold 2.

[0061] The pivot bearing 42 is installed on the pipe wall of the distribution pipeline 312, and the rotating shaft 41 is pivotally connected to the pivot bearing 42 and extends through the pivot bearing 42 toward the distribution pipeline 312 and the vibration chamber 24. There are several pivot bearings 42 along the extension direction of the rotating shaft 41, and each pivot bearing 42 is pivotally connected to the rotating shaft 41, that is, a single rotating shaft 41 can be connected to multiple pivot bearings 42, and each pivot bearing 42 is installed on the pipe wall of the distribution pipeline 312, so that the single rotating shaft 41 can rotate along multiple pivot bearings 42 at the same time.

[0062] Rotating blades 43 are provided on the rotating shaft 41 at the sliding port 321 . When circulating water is delivered through the sliding port 321 , the circulating water flows along the rotating blades 43 , causing the rotating blades 43 to drive the rotating shaft 41 to rotate, thereby providing hydraulic drive.

[0063] Among them, the rotating blades 43 are set at an angle and can be facing the water flow or sideways to the water flow. When facing the water flow sideways, they can be directly installed on the rotating shaft 41. When facing the water flow, a bevel gear set needs to be set on the rotating shaft 41, and another set of bearing seats and rotating shafts with bevel gears are set at the distribution pipe wall to provide the pivoting of the rotating blades 43. The meshing method of the bevel gear set is used to provide the transmission effect of the rotating blades 43 facing the water flow. In comparison, the side-facing water flow method is more convenient, so the diagram shows the side-facing water flow method, but the setting method can also be determined according to needs.

[0064] There are several vibration parts 44 distributed on the rotating shaft 41 in the vibration cavity 24. The vibration part 44 can be a vibration wheel. The vibration part 44 is fixedly connected to the rotating shaft 41, so that when the rotating shaft 41 rotates, it will drive the vibration wheel located in the vibration cavity 24 to rotate.

[0065] There are several rebound parts 45, which are installed in an unfolded manner on the vibration part 44. The rebound part 45 contacts the outer wall of the lower mold 2. The rebound part 45 can adopt an elastic plate with toughness and elastic effect. After the rebound part 45 is installed on the vibration part 44, the vibration part 44 rotates to drive the rebound part 45 to hit the outer wall of the lower mold 2, generating a vibration effect. At the same time, according to its elastic effect, it can bend and restore, so that the rebound part 45 bends after the impact, thereby avoiding the rebound part 45 from breaking.

[0066] Among them, when the rebound part 45 adopts an elastic plate, it can be set at an angle so that the elastic plate can hit the outer wall of the lower mold 2 from the side, and a rolling wheel can be set at the end of the elastic plate that contacts the outer wall of the lower mold 2. The rolling wheel is used to contact the outer wall of the lower mold 2. When in contact with the outer wall of the lower mold 2, the rolling wheel rolls along the outer wall of the lower mold 2, which can reduce friction and extend the service life.

[0067] On the other hand, the rebound part 45 can also be made of a flexible rope and an elastic ball. The flexible rope is tied to the vibration part 44, and the elastic ball is connected to the flexible rope. When the vibration part 44 rotates, the flexible rope and the elastic ball are subjected to the centrifugal force and collide with the outer wall of the lower mold 2. This method can reduce the wear of the rebound part 45. The figure shows it in the form of a flexible rope and an elastic ball.

[0068] Specifically, the circulating water of the sliding port 321 is used to provide driving force for the rotating blades 43, so that the rotating shaft 41 rotates along the pivot bearing 42. During the rotation, the vibration part 44 and the rebound part 45 are driven to rotate in the vibration cavity 24. The rebound part 45 hits the outer wall of the lower mold 2 to provide vibration force. At the same time, vibration is provided in several vibration cavities 24 to vibrate the material in the lower mold 2 evenly and improve the molding stability of the material.

[0069] The circulating water flowing out of the sliding port 321 can provide the driving force required for vibration when the material is not cooled, making the material uniform. Then, after the circulating water fills the distribution pipeline 312, the material is cooled, and the vibration chamber 24 can isolate the circulating water to ensure that the water flow will not affect the impact of the rebound part 45.
