Description

Technical Field

[0001] This invention relates to the field of injection molding technology, and more specifically to a cooling and demolding device for injection-molded silicone. Background Technology

[0002] Silica gel, also known as silica gel, is a granular, porous silica hydrate. It is an amorphous substance, transparent or milky white in appearance, and is produced by washing and drying sodium silicate with acid. It is insoluble in water and any solvent, non-toxic and odorless, chemically stable, and non-flammable. It has the characteristics of high temperature resistance, stable adhesion, and good durability. Generally speaking, it can be divided into two main categories: organic silica gel and inorganic silica gel. Among them, silicone trays are multifunctional silicone trays made of silicone material, with a variety of uses and features. Silicone trays are not only used in kitchens and dining tables, but are also widely used in medical, dental, baking, food processing and other fields.

[0003] In the production of silicone, injection molding is a common processing method. Silicone injection molding is a manufacturing process that involves injecting liquid silicone into a mold and shaping it under high pressure and high temperature. The basic principle is as follows: liquid silicone is injected into the mold cavity by the pressure of an injection molding machine. The silicone solidifies in the mold and forms the desired shape. It is then cooled to room temperature in the mold, and the silicone product is removed from the mold. When removing the silicone product, it needs to be demolded by a demolding device. After demolding, the silicone product also needs to undergo some post-processing, such as trimming burrs, cleaning, and inspection, to ensure product quality. This process is characterized by high precision, high efficiency, and high automation, and is suitable for mass production of silicone products with complex structures.

[0004] Patent document CN215434974U discloses an electronic blister silicone tray mold, including a base, an upper frame on the outer periphery of the upper surface of the base, a lower mold installed in the middle of the upper surface of the base, and a cavity inside the base. A vacuum pump is provided on one side of the base, and a connecting pipe is connected between the air inlet of the vacuum pump and the cavity. A first solenoid valve is installed on the connecting pipe. The air inlet of the vacuum pump is also connected to a pipe assembly, which extends to the upper middle of the lower mold. A second solenoid valve is installed on the pipe assembly, and the pipe assembly can be raised and lowered. A suction cup is fixed to the lower end of the pipe assembly. This patent connects a pipe to the air inlet of the vacuum pump, and this pipe assembly is connected to a suction cup. In this way, after blister forming, the suction cup can pick up the formed silicone tray and suck it away, which facilitates material unloading and avoids damage caused by material ejection.

[0005] However, when removing silicone trays with deep grooves from the mold, the cooling water is mostly sprayed directly onto the bottom of the tray, resulting in poor cooling and shaping of the sides. Additionally, the cooling water remaining at the bottom of the grooves may affect the subsequent suction cup adhesion. Furthermore, due to the large side area of ​​the silicone tray, meaning a large contact area between the tray's sidewall and the mold, demolding requires assistance. Simply applying an upward force to the tray using ejector pins or bottom suction cups may cause adhesion between the tray's sides and the mold, hindering the demolding process and impacting production efficiency. Summary of the Invention

[0006] This invention provides a cooling and demolding device for injection molding silicone, aiming to solve the problems in related technologies where the cooling and shaping effect on the sides of the grooves is poor when removing silicone trays with deep grooves from the mold. At the same time, the cooling water left at the bottom of the groove may affect the subsequent demolding. In addition, because the side area of ​​the silicone tray is large, that is, the contact area between the silicone tray and the mold is large, the side of the silicone tray may stick to the mold during demolding, making the demolding process difficult and affecting production efficiency.

[0007] The present invention provides a cooling and demolding device for injection molding silicone production, comprising a frame and a cooling mechanism disposed on the frame, a mold mounted on the frame, and a demolding mechanism further comprising:

[0008] The support plate is equipped with a conveying assembly and a driving component on the frame. The conveying assembly is used to move the support plate along the length or width of the frame, and the driving component is used to move the support plate up and down relative to the frame.

[0009] A water-passing rod is arranged longitudinally and threadedly engaged with a support plate. The interior of the water-passing rod is hollow and has multiple water spray holes at the bottom. A drive assembly is provided on the support plate, which can drive the water-passing rod to move up and down relative to the support plate and rotate around its own axis.

[0010] The suction cup assembly includes four suction cups and a connecting tube. The four suction cups are installed in a cross shape on the outside of the water passage rod. Each suction cup is vertically arranged so that the suction cup openings of the four suction cups face the four sides of the silicone tray groove. The connecting tube is located inside the water passage rod, and the lower end of the connecting tube is connected to the four suction cups respectively.

[0011] A sponge block is installed on the outside of the water-passing rod, and a sponge block is provided between any two adjacent suction cups.

[0012] Beneficial effects: By setting up the water-passing rod and suction cup assembly, cooling water is sprayed onto the sides and bottom of the silicone tray groove, ensuring the cooling and shaping effect of the silicone tray. By rotating the sponge block, the cooling water in the groove can be wiped away, preventing the cooling water from affecting the suction cup's adsorption of the silicone tray. In addition, setting the suction cup vertically allows it to adsorb onto the four side walls of the silicone tray groove, making the demolding process smoother.

[0013] Preferably, the driving component is a cylinder, which is connected to the conveying assembly. The output end of the cylinder extends vertically downward and is connected to the support plate via a connecting rod.

[0014] Preferably, the driving assembly includes a second cylinder and a movable plate. The second cylinder is mounted on the support plate, and its output end extends vertically downward through the support plate. The movable plate is connected to the output end of the second cylinder. The water-passing rod passes through the movable plate and is rotatably connected to it, so that the water-passing rod can move up and down synchronously while the movable plate moves up and down. The outer side of the water-passing rod is provided with a spiral groove, and the water-passing rod is threadedly engaged with the support plate through the spiral groove.

[0015] Preferably, each of the suction cups is made of an elastic material.

[0016] Beneficial effect: During the rotation of the water guide rod, the suction cup can continue to rotate by its own deformation after contacting the side wall of the silicone tray.

[0017] Preferably, the direction parallel to the radial direction of the water-passing rod is defined as the width direction of the sponge block, and the width of the sponge block is half the diagonal length of the groove of the silicone tray.

[0018] Beneficial effect: As the sponge block rotates with the water pipe, the side of the sponge block away from the water pipe can wipe the corner of the silicone tray groove.

[0019] Preferably, the lower end of the sponge block extends beyond the lower end of the water-passing rod, so that when the lower end of the water-passing rod contacts the bottom of the silicone tray groove, the lower end of the sponge block can contact the bottom of the silicone tray groove, and the sponge block is in a compressed state.

[0020] Beneficial effects: During the process of the lower end of the water-passing rod contacting and separating from the bottom of the groove, the cooling water at the bottom of the groove can be absorbed through the compression and recovery deformation of the sponge block.

[0021] Preferably, the frame is further provided with a squeezing assembly for squeezing the water in the sponge block. The squeezing assembly includes a squeezing plate and a driving structure for relative movement between the squeezing plate and the sponge block. The squeezing plate is longitudinally slidably sleeved on the outside of the water passage rod, and the sponge block is slidably mounted on the water passage rod along the axial direction of the water passage rod. When the squeezing plate and the sponge block move relative to each other, the sponge block can be compressed.

[0022] Beneficial effect: The relative movement between the sponge block and the extrusion plate can squeeze the sponge block, squeezing out the cooling water absorbed inside the sponge block.

[0023] Preferably, the driving structure consists of a driving rod longitudinally positioned at the upper end of the extrusion plate and a fixed frame mounted on the machine frame. The driving rod passes through the support plate and the moving plate, and slides longitudinally with the support plate and the moving plate respectively. A rod is connected to the upper end of the driving rod, and a spring is connected between the upper end of the extrusion plate and the moving plate. The fixed frame enables the driving rod and the support plate to be relatively fixed in the longitudinal direction.

[0024] Preferably, the frame is provided with a water leakage hole, which is located below the fixed frame.

[0025] Preferably, each of the water spray holes is inclined downwards gradually in the radial direction away from the axis of the water passage rod.

[0026] The beneficial effects of this invention are as follows:

[0027] 1. This invention is equipped with a demolding mechanism. Through the spiral descent of the water pipe, cooling water can be sprayed onto the sides and bottom of the silicone tray groove to ensure the cooling and shaping effect of the silicone tray. At the same time, the rotation of the water pipe can drive the sponge block to rotate synchronously, wiping the cooling water in the silicone tray groove and avoiding affecting the subsequent suction cup adsorption. In addition, the four vertically arranged suction cups can adsorb the four side walls of the silicone tray groove, which is conducive to the separation of the side walls of the silicone tray from the mold during the demolding process, thus making the demolding process smoother.

[0028] 2. The present invention is equipped with a squeezing component, which can squeeze out the water in the sponge block by the relative movement of the sponge block and the squeezing plate, so as to ensure the subsequent absorption effect of the cooling water by the sponge block.

Detailed Implementation

[0038] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0039] like Figures 1 to 7 As shown, a cooling and demolding device for injection molding silicone production according to the present invention includes a frame 1 and a cooling mechanism (not shown in the figure) disposed on the frame 1. A fixing plate 11 and a mold 12 are installed on the frame 1, and a demolding mechanism is also provided on the frame 1.

[0040] Specifically, the liquid silicone to be processed is injected into the mold 12 for processing, and the silicone tray 5 is made to adhere to the surface of the mold 12 by vacuum adsorption. After cooling, it forms the required shape. Then, the shaped silicone tray 5 is removed from the mold 12. The present invention is provided with a demolding mechanism, which can prevent the side wall of the silicone tray 5 from sticking to the mold 12 when demolding some silicone trays with deeper grooves, so that the demolding process can proceed smoothly.

[0041] The demolding mechanism includes a support plate 21, a water-passing rod 22, a suction cup assembly, and a sponge block 41. A conveying assembly and a driving component are provided on the frame 1. The conveying assembly moves the support plate 21 along the length or width of the frame 1, and the driving component moves the support plate 21 up and down relative to the frame 1. The water-passing rod 22 is longitudinally arranged and threadedly engaged with the support plate 21. The interior of the water-passing rod 22 is hollow. The cooling mechanism directly uses a water pump and a storage tank for storing cooling water. When the water pump is turned on, it can extract the cooling water from the storage tank for use. The upper end of the water-passing rod 22 is connected to the water pump, and the lower part of the water-passing rod 22 has multiple spray holes 221, allowing cooling water to enter the water-passing rod 22 and spray outwards from the spray holes 221. The support plate 21 is equipped with a drive assembly, which can drive the water-passing rod 22 to move up and down relative to the support plate 21 and rotate around its own axis. The suction cup assembly includes suction cups 31 and connecting pipes 32. There are four suction cups 31, which are installed in a cross shape on the outside of the water-passing rod 22. Each suction cup 31 is vertically arranged so that the suction cup openings of the four suction cups 31 face the four sides of the groove of the silicone tray 5. The connecting pipe 32 is located inside the water-passing rod 22. The upper end of the connecting pipe 32 is connected to a vacuum pump, and the lower end of the connecting pipe 32 is connected to the four suction cups 31 respectively. The sponge block 41 is installed on the outside of the water-passing rod 22, and a sponge block 41 is provided between any two adjacent suction cups 31. The conveying assembly is existing technology and will not be described in detail here.

[0042] Specifically, after the silicone tray 5 is attached to the surface of the mold 12 by vacuum adsorption, the water pump is turned on by the electronic control structure. The water pump introduces cooling water into the interior of the water-passing rod 22. The cooling water then flows downward through the gap between the water-passing rod 22 and the connecting pipe 32, and is sprayed outward from the spray hole 221 onto the surface of the groove of the silicone tray 5. At this time, the cooling water can exchange heat with the silicone tray 5, so that the silicone tray 5 can cool and solidify quickly. During this process, the water-passing rod 22 is driven downward by the drive component and rotated around its own axis, so that the cooling water can be evenly sprayed on the side wall of the groove of the silicone tray 5, which can quickly cool the side wall of the silicone tray 5, which is beneficial for subsequent demolding. During the downward movement and rotation of the water-passing rod 22, the suction cup 31 and the sponge block 41 installed on the outside of the water-passing rod 22 can move synchronously. During the rotation of the sponge block 41, the cooling water sprayed into the groove of the silicone tray 5 by the spray hole 221 on the front side can be wiped to avoid affecting the subsequent adsorption effect of the suction cup 31.

[0043] When the lower end of the water-passing rod 22 contacts the bottom of the groove in the silicone tray 5, the water-passing rod 22 stops moving downwards and stops rotating. At this time, the suction cup openings of the four suction cups 31 are facing the four sides of the groove in the silicone tray 5. The vacuum pump is turned on by the electronic control structure. The vacuum pump extracts the air from the connecting pipe 32 and the suction cups 31 to create a negative pressure state. At this time, the suction cups 31 can adhere to the side wall of the groove in the silicone tray 5, causing the side wall of the groove in the silicone tray 5 to deform to a certain extent towards the suction cups 31, so that gas can enter between the silicone tray 5 and the mold 12. This facilitates the subsequent removal of the silicone tray 5 from the mold 12. Then, the support plate 21 is driven upwards by the driving component. The movement of the water-passing rod 22, suction cup assembly, and sponge block 41 can drive the water-passing rod 22, suction cup 31, and sponge block 41 to move upwards synchronously. During this process, the silicone tray 5 can be moved upwards by the suction cup 31 and detached from the mold 12 to complete the demolding process. Cooling water is sprayed through the water spray hole 221 at the bottom of the water-passing rod 22 to cool the side wall of the groove of the silicone tray 5. The rotation of the sponge block 41 can wipe the sprayed cooling water to avoid affecting the suction effect of the suction cup 31. By setting four suction cups 31 to simultaneously suction the four side walls of the groove of the silicone tray 5, it is easier to separate the silicone tray 5 from the mold 12 and make demolding smoother.

[0044] In some embodiments, the driving component is a cylinder 23, which is connected to the conveying assembly. The output end of the cylinder 23 extends vertically downward and is connected to the support plate 21 via a connecting rod 24.

[0045] Specifically, such as Figures 1 to 6 As shown, by using vacuum adsorption, after the suction cup 31 is adsorbed onto the silicone tray 5, the cylinder 23 is activated, causing the output end of the cylinder 23 to retract, which drives the support plate 21 to move upward. This causes the water-passing rod 22, which is threadedly engaged with the support plate 21, as well as the suction cup 31 and sponge block 41 installed on the outside of the water-passing rod 22, to move upward synchronously, so that the silicone tray 5 adsorbed on the suction cup 31 is detached from the mold 12. Then, the conveying assembly drives the cylinder 23 to move along the length or width of the frame 1, and drives the support plate 21 to move synchronously along the length or width of the frame 1, so as to place the demolded silicone tray 5 in another position on the frame 1.

[0046] In some embodiments, the drive assembly includes a second cylinder 25 and a movable plate 26. The second cylinder 25 is mounted on a support plate 21, and its output end extends vertically downward through the support plate 21. The movable plate 26 is connected to the output end of the second cylinder 25. A water-passing rod 22 passes through the movable plate 26 and is rotatably connected to the movable plate 26, so that while the movable plate 26 moves up and down, it can drive the water-passing rod 22 to move up and down synchronously. A spiral groove 222 is provided on the outer side of the water-passing rod 22, and the water-passing rod 22 is threadedly engaged with the support plate 21 through the spiral groove 222.

[0047] Specifically, such as Figures 1 to 6 As shown, after the silicone tray 5 is attached to the surface of the mold 12 by vacuum adsorption, the second cylinder 25 is activated, which drives the moving plate 26 connected to the output end of the second cylinder 25 to move downward, and drives the water passage rod 22, which is rotatably connected to the moving plate 26, to move downward in sync. At this time, through the threaded engagement between the water passage rod 22 and the support plate 21, the water passage rod 22 can rotate, that is, while the water passage rod 22 moves downward, it can rotate around its own axis. After the demolded silicone tray 5 is placed in another position on the frame 1, the first cylinder 23 drives the support plate 21 to move downward to reset, and at the same time, the second cylinder 25 drives the water passage rod 22 to move upward to reset.

[0048] It should be noted that each suction cup 31 is made of elastic material. The direction parallel to the radial direction of the water-passing rod 22 is defined as the width direction of the sponge block 41. The width of the sponge block 41 is half the diagonal length of the groove of the silicone tray 5. During the process of the water-passing rod 22 rotating and driving the suction cup 31 to rotate synchronously, when the suction cup 31 touches the side wall of the groove of the silicone tray 5, the suction cup 31 can adapt to the deformation of the groove to avoid affecting the smooth rotation of the suction cup 31. Since the width of the sponge block 41 is half the diagonal length of the groove of the silicone tray 5, during the rotation of the sponge block 41, the side of the sponge block 41 away from the water-passing rod 22 can wipe the corner of the groove of the silicone tray 5.

[0049] In some embodiments, the lower end of the sponge block 41 extends beyond the lower end of the water-passing rod 22, so that when the lower end of the water-passing rod 22 contacts the bottom of the groove of the silicone tray 5, the lower end of the sponge block 41 can contact the bottom of the groove of the silicone tray 5, and the sponge block 41 is in a compressed state.

[0050] Specifically, such as Figures 1 to 5As shown, during the downward movement of the water-passing rod 22, the lower end of the sponge block 41 will first contact the bottom of the groove of the silicone tray 5. At this time, as the water-passing rod 22 continues to move downward, the sponge block 41 will be compressed upward and deformed until the lower end of the water-passing rod 22 contacts the bottom of the groove of the silicone tray 5. The water-passing rod 22 moves upward and the lower end of the water-passing rod 22 is separated from the bottom of the silicone tray 5. At this time, the sponge block 41 will deform downward and recover. During this process, the sponge block 41 can absorb the cooling water at the bottom of the silicone tray 5.

[0051] After a period of use, the sponge block 41 will absorb a lot of cooling water. If the cooling water in the sponge block 41 is not squeezed out in time, it will affect the subsequent use of the sponge block 41. Therefore, in some embodiments, a squeezing assembly for squeezing the water in the sponge block 41 is also included. The squeezing assembly includes a squeezing plate 42 and a driving structure for relative movement between the squeezing plate 42 and the sponge block 41. The squeezing plate 42 is longitudinally slidably sleeved on the outside of the water passage rod 22. The sponge block 41 is slidably mounted on the water passage rod 22 along the axial direction of the water passage rod 22. When the squeezing plate 42 and the sponge block 41 move relative to each other, the sponge block 41 can be compressed.

[0052] Specifically, such as Figures 2 to 7 As shown, when it is necessary to squeeze out the cooling water absorbed in the sponge block 41, the squeezing plate 42 and the sponge block 41 are moved relative to each other by the driving component. When the end of the sponge block 41 close to the squeezing plate 42 comes into contact with the squeezing plate 42, the sponge block 41 will be squeezed and compressed along the axial direction of the water passage rod 22 as the two move relative to each other. In this process, the water in the sponge block 41 can be squeezed out, ensuring the wiping effect of the sponge block 41 on the groove of the silicone tray 5.

[0053] In some embodiments, the driving structure consists of a driving rod 43 longitudinally disposed on the upper end of the extrusion plate 42 and a fixed frame 44 disposed on the frame 1. The driving rod 43 passes through the support plate 21 and the moving plate 26, and slides longitudinally with the support plate 21 and the moving plate 26 respectively. A rod 431 is connected to the upper end of the driving rod 43. A spring 45 is connected between the upper end of the extrusion plate 42 and the moving plate 26. The fixed frame 44 enables the driving rod 43 to be fixed relative to the support plate 21 in the longitudinal direction. A drain hole 100 is provided on the frame 1, and the drain hole 100 is disposed below the fixed frame 44.

[0054] During the use of the demolding mechanism, it can be set to perform a compression squeeze on the sponge block 41 once after completing a set number of demolding cycles. Specifically, for example... Figures 1 to 7As shown, during the downward movement of the moving plate 26 driven by cylinder 25, the squeezing plate 42 and the drive rod 43 move synchronously. When the lower end of the water-passing rod 22 contacts the bottom of the groove of the silicone tray 5, the upper part 431 of the drive rod 43 contacts the support plate 21. After adsorbing the silicone tray 5, the support plate 21 is moved along the length or width of the frame 1 by the conveying assembly. After the silicone tray 5 adsorbed by the suction cup 31 is placed in another position on the frame 1, the support plate 21 is moved downward by cylinder 23 to reset. Then, the support plate 21 is moved along the length or width of the frame 1 towards the fixed frame 44 by the conveying assembly, so that the support plate 21 is directly below the fixed frame 44. Since the moving plate 26 has not reset at this time, the squeezing plate 42 and the drive rod 43 have also not reset, thus moving the support plate 21 directly below the fixed frame 44. At this time, the rod 431 is positioned between the support plate 21 and the fixed frame 44, preventing the rod 431 from moving up and down. This allows the drive rod 43 and the support plate 21 to be relatively fixed in the longitudinal direction. At this time, the cylinder 25 drives the moving plate 26 to move upward, while the pressing plate 42 remains stationary, causing the spring 45 to stretch and store force. As the moving plate 26 moves upward, it can drive the water-passing rod 22 and the sponge block 41 installed on the outside of the water-passing rod 22 to move upward synchronously. Through the relative movement of the sponge block 41 and the pressing plate 42, the sponge block 41 can be squeezed, causing the cooling water squeezed out of the sponge block 41 to be discharged through the drain hole 100 on the frame 1 to the bottom of the frame 1. After the sponge block 41 is squeezed, the conveying assembly drives the support plate 21 to move out from under the fixed frame 44. At this time, the pressing plate 42 and the drive rod 43 will move towards the moving plate 26 under the action of the spring 45 to reset.

[0055] In some embodiments, each spray hole 221 is gradually inclined downward along the radial direction of the water passage rod 22 away from the axis of the water passage rod 22.

[0056] Specifically, the water spray hole 221 is set at an angle so that when the cooling water is sprayed outward, it can not only spray onto the side of the groove of the silicone tray 5 to cool the side, but also spray a portion of the cooling water onto the bottom of the groove of the silicone tray 5 to cool the bottom, so as to ensure the shaping effect of the silicone tray 5.

[0057] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
