Description

Technical Field

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

[0002] A disposable paper lunch box is a common green and environmentally friendly tableware. Among them, the paper lunch box includes a box body and a lid connected as a whole. On at least one of the lid or the box body, there is a plug - in part, and on the other part, there is a socket. When the box body and the lid are folded and closed, the plug - in part is inserted into the socket to be closed and clamped. And the connecting part between the lid and the box body of the paper lunch box needs to form a bending mark through a pre - pressing method to facilitate the folding of the lid and the box body.

[0003] When forming a paper lunch box, a forming mold is required. After forming a disposable paper lunch box from pulp, two processes of pre - pressing to form a bending mark and punching to form a socket are also required. Adopting this scheme not only requires additional equipment, but also increases the cost required for production after adding two processes. Therefore, it needs to be improved. Summary of the Invention

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

[0005] The one - time forming mold and system assembly for disposable paper lunch boxes provided by the present application adopt the following technical solutions: A one - time forming mold for disposable paper lunch boxes includes an upper mold and a lower mold. The styles of the upper mold and the lower mold are both divided into a lid section, a connecting section, and a box body section. The connecting section is located between the lid section and the box body section and connects the two. The lower mold is provided with a socket forming part and a pre - crease forming part. The socket forming part is located within the lid section, and the socket of the paper lunch box is formed by the cooperation of the lower mold and the upper mold. The pre - crease forming part is located in the connecting section and forms a pre - crease when the molds are closed. The upper mold is provided with a pouring port for injecting materials. The upper mold and the lower mold inject materials in the closed - mold state, and the paper lunch box is formed after cooling. The upper mold is provided with connecting protrusions for forming pre - creases, and the lower mold is provided with pre - crease grooves. The pre - crease forming part is located within the pre - crease grooves. The connecting protrusions and the pre - crease grooves form a wavy spaced - apart space. The pre - crease forming part reduces the distance between the connecting protrusions and the pre - crease grooves, further narrowing the wavy spaced - apart space. When the wavy spaced - apart space is filled with materials to form the wavy connecting part of the paper lunch box, the pre - crease forming part and the connecting protrusions reduce the thickness of the connecting part. The connecting protrusions form the concave of the wavy connecting part, providing a placement space for the chopsticks used with the paper lunch box.

[0006] By adopting the above technical solution, when the upper mold and the lower mold are in the closed mold state, materials are injected through the pouring port, and the filling space between the upper mold and the lower mold is filled with the materials. During filling, the materials are separated by the socket forming part, and the pre-crease forming part extrudes the materials at the connecting section to form a pre-crease. After cooling and demolding, the upper mold and the lower mold are separated. The materials at the lid section form a socket, and a pre-crease is formed at the connecting section. The connecting protrusion and the pre-crease groove form a wavy spaced space, so that when forming a paper food box, the lid and the box body can be folded along the wavy connecting part. The pre-crease forming part reduces the distance between the connecting protrusion and the connecting groove, making the wavy spaced space further reduced and the thickness decreased. The thickness reduction can make the wavy connecting part easier to bend and can be folded at a larger angle, ensuring the stability of the connection during use. If the thickness is too large, when the lid and the box body are closed, the same folding angle is likely to cause the connecting part to break. By reducing the thickness, the connecting part between the lid and the box body has greater toughness and stronger anti-breaking property. After filling the materials in the wavy spaced space, an inner concave space is formed at the wavy connecting part corresponding to the connecting protrusion. Users can put tools such as chopsticks that are used in conjunction with the paper food box into the inner concave space. When the box body and the lid are folded and fastened to each other, the tools such as chopsticks are restricted in the inner concave space, which is convenient for storing tools such as chopsticks and can also prevent the loss of tools such as chopsticks.

[0007] Optionally, the upper mold is a smooth casting, and the lower mold is a casting with a dense metal woven mesh laid on its surface.

[0008] By adopting the above technical solution, the surface of the casting used for the upper mold is smooth, so that when contacting the materials, the surface where the materials are formed is a smooth surface, which can correspond to the inner wall of the paper food box and is convenient for holding food. The metal woven mesh of the lower mold can form the outer wall of the paper food box into a texture of a metal woven mesh when the materials are cooled and formed, thereby providing an anti-slip effect, and users can contact more stably and comfortably when using the paper food box.

[0009] Optionally, the crease forming part includes a semi-circular forming rod; the forming rod is spaced from the groove wall of the pre-crease groove by a preset distance.

[0010] By adopting the above technical solution, the arc-shaped forming rod reduces the space between the upper mold and the lower mold at the connecting section, and then uses the pre-crease groove to form a crease. At the same time, the preset spaced distance from the connecting groove can further increase the trace depth of the pre-crease during forming, making it easier for the lid and the box body to be folded. The arc shape can fit the folding radian of the box body and the lid.

[0011] Optionally, a shaping component is further arranged in the lower mold, and the shaping component is externally connected with a circulating pipe fitting for conveying circulating water.

[0012] By adopting the above technical solution, the circulating pipe fittings convey the circulating water into the shaping assembly, and the shaping assembly rapidly cools the lower mold by means of water cooling, thereby improving the molding efficiency.

[0013] Optionally, the shaping assembly includes a water cooling pipeline, which is divided into two sections. The first section is the pre-crease pipeline, and the second section is the distribution pipeline. The pre-crease pipeline is located in the connection section, and the distribution pipeline is laid on the cover section and the box section; the inlet of the water cooling pipeline is located in the pre-crease pipeline, and the outlet is located in the distribution pipeline.

[0014] By adopting the above technical solution, the circulating water will first cool the connection section and the pre-crease forming part, and then gradually cool the box section and the cover section. After cooling and solidifying the material at the connection section, the box section and the cover section are cooled, so as to ensure that the material at the pre-crease can be stably cooled and solidified into shape.

[0015] Optionally, a sliding part is slidably connected in the pre-crease pipeline, and a sliding opening is formed in the sliding part; one end of the sliding part extends towards the distribution pipeline, and when the sliding part slides along the pre-crease pipeline, the sliding opening is gradually communicated with the distribution pipeline; a connecting part is provided on the distribution pipeline, and an elastic part is provided on the connecting part, and the elastic part is connected to the sliding part and provides elastic force.

[0016] By adopting the above technical solution, when the circulating water enters the pre-crease pipeline, the circulating water exchanges heat with the heat of the material in contact with the connection section of the lower mold and the pre-crease forming part through the pre-crease pipeline. As the water flow continuously enters 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 opening is gradually communicated with the distribution pipeline, so that the water flow can be conveyed into the distribution pipeline, ensuring that the circulating water first cools the pre-crease pipeline and then is conveyed into the distribution pipeline for cooling.

[0017] Optionally, a vibration assembly is further provided at the position where the distribution pipeline is communicated with the sliding opening. The vibration assembly extends in the distribution pipeline and transmits the vibration force to the wall surface of the lower mold through the distribution pipeline.

[0018] By adopting the above technical solution, the vibration assembly uses the circulating water flowing out of the sliding opening to generate driving force to provide vibration, and vibrates the material that has not been cooled in the lower mold, so that the material is more evenly distributed in the lower mold through vibration. Therefore, the vibration assembly extends in the distribution pipeline, covering both the cover section and the box section.

[0019] Optionally, the vibration assembly includes a rotating shaft, a pivot bearing, a rotating blade, a vibration part, and a resilience part; in the distribution pipeline, adjacent pipelines are spaced apart 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 towards the distribution pipeline and the vibration cavity; a plurality of pivot bearings are arranged along the extension direction of the rotating shaft, and each pivot bearing is pivotally connected to the rotating shaft; a rotating blade is provided on the rotating shaft at the sliding port; a plurality of vibration parts are provided and distributed on the rotating shaft in the vibration cavity; a plurality of resilience parts are provided and are installed on the vibration part in an unfolded manner, and the resilience part contacts the outer wall of the lower mold.

[0020] By adopting the above technical solution, the circulating water at the sliding port is used to provide driving force for the rotating blade, so that the rotating shaft rotates along the pivot bearing. During the rotation process, the vibration part and the resilience part are driven to rotate in the vibration cavity, and the resilience part impacts the outer wall of the lower mold to provide vibration force. At the same time, vibration is provided in a plurality of vibration cavities to vibrate the materials in the lower mold evenly and improve the forming stability of the materials.

[0021] A molding system assembly includes a collector mechanism, an electrical mechanism, an injection molding mechanism, a shaping component, a mobile conveying mechanism, a pipeline mechanism, a screen washing device, a circulating pipe fitting, and the molding die.

[0022] By adopting the above technical solution, the molding system assembly provides the overall opening and closing of the molding die, as well as steps such as material conveying, cooling and shaping, and collection, to complete the processing flow of the entire paper food box.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. When the upper mold and the lower mold are in the closed mold state, materials are injected through the gating system. The materials fill the filling space between the upper mold and the lower mold. During filling, the materials are separated by the socket forming part, and the pre-crease forming part extrudes the materials at the connecting section to form pre-creases. After cooling and demolding, the upper mold and the lower mold are separated. The materials at the lid section form sockets, and pre-creases are formed at the connecting section. The connecting protrusions and the pre-crease grooves form a wavy spaced space. When forming a paper food container, the lid and the container body can be folded along the wavy connecting part. The pre-crease forming part reduces the distance between the connecting protrusions and the connecting grooves, making the wavy spaced space further reduced and the thickness decreased. The reduced thickness enables the wavy connecting part to be more easily bent and folded at a larger angle, ensuring the stability of the connection during use. If the thickness is too large, when the lid and the container body are closed, the same folding angle is likely to cause the connecting part to break. By reducing the thickness, the connecting part between the lid and the container body has greater toughness and stronger anti-breaking ability. After filling the materials, an inner concave space is formed at the wavy connecting part corresponding to the connecting protrusions. Users can place tools such as chopsticks that are used with the paper food container into the inner concave space. When the container body and the lid are folded and fastened to each other, the tools such as chopsticks are restricted within the inner concave space, which is convenient for storing tools such as chopsticks and can also prevent the loss of these tools. 2. The casting used for the upper mold has a smooth surface. When contacting the materials, the surface where the materials are formed is a smooth surface, which can correspond to the inner wall of the paper food container and is convenient for holding food. The metal woven mesh of the lower mold can form the outer wall of the paper food container into a texture with a metal woven mesh pattern when the materials are cooled and formed, thereby providing an anti-slip effect, enabling users to have a more stable and comfortable contact when using the paper food container. 3. The arc-shaped forming rod reduces the space 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 spaced distance between the connecting grooves can further increase the trace depth of the pre-crease during forming, making the lid and the container body easier to fold. The arc shape can fit the folding arc of the container body and the lid. Description of the Drawings

[0030] The following will further elaborate on this application in conjunction with the attached Figure 1 - attached Figure 6 drawings.

[0031] The embodiments of this application disclose a one - time forming mold and a system assembly for a disposable paper food container.

[0032] A one - time forming mold for a disposable paper food container, referring to Figure 1 and Figure 2 as shown, includes an upper mold 1 and a lower mold 2. Referring to Figure 3 and Figure 4 as shown, the styles of the upper mold 1 and the lower mold 2 are both divided into a lid section 12, a connecting section 13, and a box body section 14. After the upper mold 1 and the lower mold 2 are closed and filled with materials, the materials in the lid section 12 form the lid of the paper food container, the materials in the box body section 14 form the box body of the paper food container, and the materials in the connecting section 13 form a bendable or pivotable connecting part 33 between the lid and the box body. Therefore, the lid 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, enabling the paper food container to be completely formed when filling with materials.

[0033] Referring 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 food container is filled with 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, they need to be fixed to prevent the lid from opening. Therefore, the socket forming part 21 is provided. When the upper mold 1 and the lower mold 2 are closed and filled with materials, since the socket forming part 21 blocks the materials, when demolding, the part of the paper food container separated by the socket forming part 21 forms a socket. The box body section 14 of the lower mold 2 and the upper mold 1 is provided with a convex groove for forming a connecting convex 15. After the convex groove is filled with materials, it forms a connecting convex 15, and the connecting convex 15 is used to plug into the socket.

[0034] The pre - crease forming part 22 is located in the connecting section 13 and is used to form a pre - crease for bending the lid and the box body when closing the mold and filling with materials.

[0035] The upper mold 1 is provided with a pouring port 11 for injecting materials. The number of pouring ports 11 can be set to several. After closing the mold, providing the pouring port 11 can convey and pour the materials into the filling space between the upper mold 1 and the lower mold 2.

[0036] Specifically, in the mold-closed state of the upper mold 1 and the lower mold 2, materials are injected through the pouring gate 11. The materials fill the filling space between the upper mold 1 and the lower mold 2. During filling, the materials are separated by the socket forming part 21, and the pre-crease forming part 22 extrudes the materials at the connecting section 13 to form pre-creases. After cooling and demolding, the upper mold 1 and the lower mold 2 are separated. The materials at the cover body section 12 form sockets, and the materials at the connecting section 13 form pre-creases.

[0037] Furthermore, the upper mold 1 is a smooth casting. The surface of the casting used for the upper mold 1 is smooth, so that when contacting the materials, the surface formed by the materials is a smooth surface, which can correspond to the inner wall of the paper food box and is convenient for holding food. The lower mold 2 is a casting with a dense metal braided mesh laid on its surface, corresponding to the outer wall of the formed paper food box, so that the metal braided mesh can form the outer wall of the paper food box into a texture of a metal braided mesh when the materials are cooled and formed, thereby providing an anti-slip effect. When users use the paper food box, they can contact it more stably and comfortably. The metal braided mesh of the lower mold 2 can be referred to Figure 4 as shown.

[0038] In some embodiments, referring to 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 part 22 is located in the pre-crease groove 23. Both the connecting protrusion 15 and the pre-crease groove 23 are located in the corresponding connecting section 13. The connecting protrusion 15 and the pre-crease groove 23 form a wavy spaced space. When forming the paper food box, the wavy spaced space is filled with materials and forms a wavy connecting part at the connection between the box body and the box cover. The wavy connecting part can achieve the function of pre-bending, enabling the box cover and the box body to be folded along the wavy connecting part. The pre-crease forming part 22 reduces the distance between the connecting protrusion 15 and the connecting groove, synchronously reducing the wavy spaced distance, so that the thickness of the formed wavy connecting part is reduced. The reduced thickness makes the wavy connecting part easier to bend and can be folded at a larger angle, ensuring the stability of the connection during use. If the thickness is too large, when the box cover and the box body are closed, the same folding angle is likely to cause the connecting part to break. By reducing the thickness, the connecting part between the box cover and the box body has greater toughness and stronger anti-breaking ability.

[0039] After the wavy spaced space is filled with materials, an inner concave space is formed at the wavy connecting part corresponding to the connecting protrusion 15. Users can put tools such as chopsticks that are used with the paper food box into the inner concave space. When the box body and the box cover are folded and fastened to each other, the tools such as chopsticks are restricted in the inner concave space, which is convenient for storing tools such as chopsticks and can also prevent the loss of tools such as chopsticks.

[0040] Furthermore, referring to Figure 2As shown, the pre-crease forming part 22 includes a semi-circular forming rod; there is a preset distance between the forming rod and the groove wall of the pre-crease groove 23. The semi-circular forming rod reduces the interval between the upper die 1 and the lower die 2 at the connecting section 13. Combining with the distance between the forming rod and the groove wall of the pre-crease groove 23, it can further increase the trace depth of the pre-crease, making it easier to fold the box cover and the box body. The arc style can fit the folding arc of the box body and the box cover.

[0041] In some embodiments, referring to Figure 5 As shown, a shaping component 3 is further provided in the lower die 2. The shaping component 3 is externally connected with a circulating pipe fitting for conveying circulating water. The circulating pipe fitting conveys the circulating water into the shaping component 3, and the shaping component 3 rapidly cools the lower die 2 by means of water cooling, improving the forming efficiency.

[0042] Furthermore, the shaping component 3 includes a water-cooling pipeline 31. The water-cooling pipeline 31 is divided into two sections. The first section is the pre-crease pipeline 311, and the second section is the distribution pipeline 312. The pre-crease pipeline 311 is connected to the connecting section 13. The circulating water in the pre-crease pipeline 311 exchanges heat with the connecting section 13 in the lower die 2 and the wall surface of the pre-crease forming part 22, rapidly reducing the high temperature of the material, so that the material at the connecting part 33 can be cured faster. The distribution pipeline 312 is laid on the cover body section 12 and the box body section 14 to accelerate the cooling of the materials of the cover body section 12 and the box body section 14.

[0043] 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 conveying path of the circulating water is 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 thickness of the pre-crease formed at 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 cured, the box body section 14 and the cover body section 12 are cooled, so as to ensure that the material at the pre-crease can be stably cooled and cured into shape.

[0044] Even further, referring to Figure 6As shown, a sliding part 32 is slidably connected inside the pre-fold line pipeline 311. The sliding part 32 can be a sliding column. The sliding part 32 can block the water flow path of the pre-fold line pipeline 311. A sliding opening 321 is formed in the sliding part 32. The sliding opening 321 is a T-shaped opening, that is, it has three water outlet channels. The sliding opening 321 is used to provide the circulation of the water flow path. One end of the sliding part 32 extends towards the distribution pipeline 312. When it can slide along the pre-fold line pipeline 311, it extends into the distribution pipeline 312. And when the sliding part 32 slides along the pre-fold line pipeline 311, the sliding opening 321 is gradually communicated with the distribution pipeline 312, thereby gradually opening the water flow path, so that the circulating water can flow through the sliding opening 321 to the distribution pipeline 312.

[0045] The distribution pipeline 312 is provided with a connecting part 33. An elastic part 34 is provided on the connecting part 33. The elastic part 34 is connected to the sliding part 32 and provides an elastic force. The connecting part 33 can be a connecting ring. The two ends of the sliding column used for the sliding part 32 have different diameters. The diameter of the end close to the connecting ring matches the inner diameter of the connecting ring. The end far from the connecting ring is located inside the pre-fold line pipeline 311 and matches the inner diameter of the pre-fold line pipeline 311, so that the pre-fold line pipeline 311 can be just blocked.

[0046] The elastic part 34 can be a spring. The elastic part 34 exerts an elastic force on the sliding part 32 towards the pre-fold line pipeline 311. So that when the sliding part 32 is affected by the water flow, the water pressure will squeeze the elastic part 34, so that it slides towards the connecting part 33 to gradually open the water flow path between the sliding opening 321 and the distribution pipeline 312.

[0047] Specifically, when the circulating water enters the pre-fold line pipeline 311, the circulating water exchanges heat with the heat of the material in contact with the connection section 13 of the lower mold 2 and the pre-fold line forming part 22 through the pre-fold line pipeline 311. As the water flow continuously enters the pre-fold line pipeline 311, the water pressure inside the pre-fold line 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-fold line pipeline 311 and the connecting part 33 until the sliding opening 321 is gradually communicated with the distribution pipeline 312, so that the water flow can be transported into the distribution pipeline 312, ensuring the function that the circulating water first cools the pre-fold line pipeline 311 and then is transported into the distribution pipeline 312 for cooling.

[0048] In some embodiments, referring to Figure 5 and Figure 6 As shown, a vibration assembly 4 is also provided at the place where the distribution pipeline 312 is communicated with the sliding opening 321. The function of the vibration assembly 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 assembly 4 transmits the vibration force to the wall surface of the lower mold 2 through the distribution pipeline 312, and the driving force for generating vibration can be the circulating water flowing out of the sliding opening 321.

[0049] The vibration assembly 4 extends to the distribution pipeline 312 so as to cover both the cover body section 12 and the box body section 14. There is less material in the connection section 13 and it is not suitable for vibration to avoid material breakage. At the same time, the pre-folded pipeline 311 will first cool and solidify the material in the connection section 13 and then convey circulating water to provide drive for the vibration assembly 4. Therefore, the material in the connection section 13 will not be affected by vibration.

[0050] Further, referring to 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 resilience part 45; in the distribution pipeline 312, between adjacent pipelines, there is a vibration cavity 24 spaced apart, and the inner cavity wall of the vibration cavity 24 can directly be the outer wall of the lower die 2.

[0051] The pivot bearing 42 is installed at the pipe wall of the distribution pipeline 312. The rotating shaft 41 is pivotally connected to the pivot bearing 42 and extends through the pivot bearing 42 towards the distribution pipeline 312 and the vibration cavity 24. A number of pivot bearings 42 are arranged along the extending 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 at the pipe wall of the distribution pipeline 312, so that the single rotating shaft 41 can rotate along multiple pivot bearings 42 simultaneously.

[0052] A rotating blade 43 is provided on the rotating shaft 41 located at the sliding port 321. When the sliding port 321 conveys circulating water, the circulating water flows along the rotating blade 43, which will cause the rotating blade 43 to drive the rotating shaft 41 to rotate to provide hydraulic drive.

[0053] Among them, the rotating blade 43 is inclined and can face the water flow directly or sideways. When facing the water flow sideways, it can be directly installed on the rotating shaft 41. When facing the water flow directly, a bevel gear set needs to be provided on the rotating shaft 41, and another set of bearing seats is provided at the distribution pipe wall and a rotating shaft with bevel gears is provided to provide pivoting for the rotating blade 43. The meshing method of the bevel gear set is used to provide the transmission effect for the rotating blade 43 facing the water flow directly. In comparison, the method of facing the water flow sideways is more convenient. Therefore, the method of facing the water flow sideways is adopted in the figure, but the setting method can also be determined according to requirements.

[0054] A number of vibration parts 44 are provided and distributed on the rotating shaft 41 in the vibration cavity 24. The vibration part 44 can adopt a vibration wheel. The vibration part 44 is fixedly connected to the rotating shaft 41, so that during the rotation of the rotating shaft 41, it will drive the vibration wheel to rotate in the vibration cavity 24.

[0055] There are several resilient parts 45, which are installed on the vibrating part 44 in an unfolded manner. The resilient part 45 is in contact with the outer wall of the lower die 2. The resilient part 45 can be made of an elastic plate with toughness and elasticity. After the resilient part 45 is installed on the vibrating part 44, the vibrating part 44 rotates to drive the resilient part 45 to impact the outer wall of the lower die 2, generating a vibrating effect. At the same time, according to its elastic effect, it can be bent and restored, so that the resilient part 45 bends after impact, thus avoiding the fracture of the resilient part 45.

[0056] Among them, when the resilient part 45 is made of an elastic plate, it can be inclined so that the elastic plate can impact the outer wall of the lower die 2 from the side. A rolling wheel can be arranged at one end of the elastic plate in contact with the outer wall of the lower die 2. The rolling wheel is used to contact the outer wall of the lower die 2, and the rolling wheel rolls along the outer wall of the lower die 2 when contacting the outer wall of the lower die 2, which can reduce the friction and extend the service life.

[0057] On the other hand, the resilient part 45 can also be made of a flexible rope and an elastic ball. The flexible rope is tied to the vibrating part 44, and the elastic ball is connected to the flexible rope. When the vibrating part 44 rotates, the flexible rope and the elastic ball are affected by the centrifugal force and impact the outer wall of the lower die 2. This method can reduce the wear of the resilient part 45, and the figure shows it in the form of a flexible rope and an elastic ball.

[0058] Specifically, the circulating water in the sliding port 321 is used to provide the driving force for the rotating blade 43, so that the rotating shaft 41 rotates along the pivot bearing 42. During the rotation process, the vibrating part 44 and the resilient part 45 are driven to rotate in the vibrating cavity 24. The resilient part 45 impacts the outer wall of the lower die 2 to provide a vibrating force. At the same time, vibrations are provided in several vibrating cavities 24 to vibrate the materials in the lower die 2 evenly and improve the forming stability of the materials.

[0059] 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. Subsequently, after the circulating water fills the distribution pipeline 312, it cools the material. The vibrating cavity 24 can isolate the circulating water to ensure that the water flow will not affect the impact of the resilient part 45.

[0060] This application also provides a forming system assembly, refer to Figure 1 As shown, it includes a collector mechanism, an electrical mechanism, an injection molding mechanism, a shaping component 3, a mobile conveying mechanism, a pipeline mechanism, a screen washing device, circulating pipe fittings, and the forming mold in the above embodiment.

The injection molding mechanism provides the injection molding of the materials. The shaping component 3 provides the cooling and shaping of the materials. The mobile conveying mechanism provides the conveyance of the products. The pipeline mechanism is connected to the injection molding mechanism to provide the conveyance of the materials.
