GMT material integrated multi-insert and multi-slider mold for insert molding

Abstract

This invention discloses a mold for GMT material integration using multiple inserts and sliders to achieve insert molding, comprising a lower mold, an upper mold, and a wedge block assembly. The wedge block assembly is disposed on the inner side of the upper mold and includes a mounting bracket. A wedge block body is mounted on the bottom of the mounting bracket. A slider assembly is disposed on the inner side of the upper mold and includes a mounting plate. A slider body is mounted on the other end of the connecting column. This invention, by disposing of the wedge block assembly on the inner side of the upper mold, allows the slider assembly to activate a cylinder that pushes the slider body. When the shock-absorbing frame at the bottom of the connecting bracket contacts the signal detection component on the bottom wall of the irregular frame, the wedge block body moves into position for the press to close the mold. This further stabilizes and limits the slider body, effectively preventing material from entering the slider hole during molding, causing slider jamming and incomplete slider forming, preventing lateral displacement of the slider, and ensuring the molding quality of the mold.

Description

Technical Field

[0001] This invention relates to the field of GMT material integration processing technology, specifically a mold for integrating multiple inserts and multiple sliders in GMT material to achieve insert molding. Background Technology

[0002] GMT is a prepreg of glass fiber thermoplastics, similar to thermosetting SMC. It is a semi-finished sheet made of glass fiber and thermoplastic. It can be softened by heating and then placed in a mold press, and then stamped and cooled to make various products. GMT is widely used in transportation and other sectors as a material for containers, bridges, corrosion protection, and electrical applications.

[0003] The defects of existing molds are:

[0004] 1. Patent document CN217704246U discloses a horizontal compression molding die, "comprising: a first cavity mold, a second cavity mold, and a core. The first cavity mold and the second cavity mold are assembled to form a molding cavity for molding products. The core is disposed within the molding cavity. The characteristic feature is that the assembly or disassembly direction of the first cavity mold and the second cavity mold is perpendicular to the arrangement direction of the core height; the end of the core is provided with a locking surface, and the first cavity mold is provided with a locking block. The locking block cooperates with the locking surface to confine the core within the molding cavity. For composite material shell products with large heights, this reduces mold complexity, lowers mold costs, reduces mold failures, and ensures smooth production of product quality. It reduces heat transfer differences, improves temperature uniformity throughout the molding process, ensures uniform thermosetting, and, combined with the reduced product wall thickness offset due to increased mold rigidity, thus improving product quality." However, during the compression molding process, material easily enters the slider hole, causing slider jamming and incomplete slider molding. Lateral slider movement cannot guarantee the molding quality of the die.

[0005] 2. Patent document CN207577251U discloses an aluminum alloy molding die for a bullet visor. "An aluminum alloy molding die for a bullet visor includes an upper die and a lower die that cooperates with the upper die; the upper die is provided with a first lifting hole, an upper die hole, a first keyway, and a guide through hole; the lower die is provided with a second lifting hole, a lower die hole, a second keyway, a guide hole, and jaws. This utility model is used for molding aluminum alloy for bullet visors." However, this molding die does not provide stable fixation between the upper and lower visors. During molding, the material flow to the upper die may shift, and material may easily adhere to the guide hole, failing to guarantee the stability of the molding die during molding.

[0006] 3. Patent document CN209633807U discloses a composite material compression molding die. "This composite material compression molding die includes an upper die, a lower die, and a heat-conducting block. The upper and lower dies are interlocked. The upper die and / or lower die have thickness regions. When the upper die has a thickness region, that region is thicker than other regions of the upper die. Conversely, when the lower die has a thickness region, that region is thicker than other regions of the lower die. The heat-conducting block is embedded in the corresponding thickness region of the upper or lower die. By embedding the heat-conducting block in the region, the composite material compression molding die can quickly transfer heat to the thickness region, thus ensuring that the thickness region has a consistent temperature with other regions." This compression molding device cannot buffer the impact forces during the molding process. Large impact forces can easily damage the upper and lower dies, shortening the service life of the molding die.

[0007] 4. Patent document CN216152809U discloses a composite material segmented compression molding die structure. "This structure includes an upper die, a lower die, a cooling die, a pad, a fixing block, a spring, a guide rod, and a base plate. The upper and lower dies have multiple pre-installed heating rod holes, with the heating rods parallel to each other. The cooling die has a through channel for placing a water inlet pipe or an oil inlet pipe. The cooling die is connected to the fixing block by rivets, the pad and fixing block are connected by bolts, the pad and the upper and lower dies are connected by springs, the fixing block is welded to the base plate, and the guide rod connects the upper and lower dies." The mold features a fixed block and guide rod perpendicular to the substrate. The mold section is designed with at least two segments, each with a different temperature setting, ensuring varying temperatures across different parts of the molding die. This segmented temperature design allows for continuous molding of composite materials, producing sheets or profiles of unlimited length without weld lines. It is practical, simple, safe, reliable, and easy to promote. However, this molding die makes it inconvenient to fix the guide rod and substrate. Damage to the die requires complete disassembly of both the upper and lower molds, hindering repair and replacement by workers. Summary of the Invention

[0012] Preferably, a signal detection component is installed inside the insertion hole. The signal detection component includes a mounting frame, an insertion block is installed on the top of the mounting frame, a connecting block is installed on the top of the insertion block, a moving groove is provided on the outer side of the connecting block, a moving plate is fitted inside the moving groove, a return spring is installed on the inner wall of the moving groove, and the outer end of the return spring is connected to the inner side of the moving plate. A locking post is installed on the outer side of the moving plate, and a connecting ring is threaded to the bottom of the mounting frame. A contact sensor is installed at the bottom of the connecting ring.

[0013] Preferably, the mounting bracket is located inside the groove, the mounting plate is located outside the upper mold, the preload rod cooperates with the pre-embedded insert, and the locking post is engaged inside the limiting hole.

[0014] Preferably, a lower template is installed at the bottom of the lower mold, an installation cavity is provided inside the lower mold, a cooling pipe is provided on the inner side of the installation cavity, a water inlet is provided at one end of the cooling pipe, a water outlet is provided at the other end of the cooling pipe, a pre-embedded insert is installed on the inner wall of the lower mold, and a positioning post is installed on the top of the lower mold, and the positioning post cooperates with the upper mold.

[0015] Preferably, an upper template is installed on the top of the upper mold, and an installation cavity 2 is provided inside the upper mold. A cooling pipe 2 is provided on the inner side of the installation cavity 2. A water inlet 2 is provided at one end of the cooling pipe 2, and a water outlet 2 is provided at the other end of the cooling pipe 2.

[0016] Preferably, a limit frame is installed on the inner wall of the upper mold, a sliding plate is installed on the outer side of the output end of the second cylinder, and the sliding plate moves inside the limit frame. A shock-absorbing frame is installed on the top of the first connecting frame, a mounting groove is provided on the top of the shock-absorbing frame, a damper is installed on the inner side of the mounting groove, a buffer spring is installed on the outer side of the damper, a buffer plate is installed on the top of the buffer spring, and the buffer plate cooperates with the contact sensor.

[0017] Preferably, the working steps of the mold are as follows:

[0018] S1. First, the prepreg is placed into the mold. The positioning pin cooperates with the upper mold to limit the upper mold and ensure that the embedded insert will not move in the horizontal direction. The slider assembly works and the cylinder two runs to push the slider body. During the movement of the slider body, the sliding plate moves inside the limit frame. When the signal detection component inside the limit frame contacts the sliding plate, the slider body moves into place.

[0019] S2. Before the mold is closed and the material has not flowed to the position of the embedded insert, the pre-pressing mechanism works. The cylinder moves to push the distance screw, causing the pre-pressing rod to move downward to press and limit the top of the embedded insert.

[0020] S3. After the molding is completed, the cylinder retracts and pulls the fixed frame to move the wedge block body upward. When the shock-absorbing frame at the top of the connecting frame contacts the signal detection component on the inner side of the top of the irregular frame, the wedge block body exits into place.

[0021] S4. When the signal detection component is damaged, press the locking pin. The locking pin presses the moving plate to move inside the moving groove and squeezes the reset spring, causing the locking pin to disengage from the limiting hole and be located inside the moving groove. This releases the limiting relationship between the limiting frame and the connecting block, allowing the signal detection component to be disassembled from the inside of the insertion hole. Rotating the connecting ring releases the threaded connection between the connecting ring and the mounting frame, allowing the contact sensor to be inspected and replaced.

[0022] Preferably, step S1 further includes the following steps:

[0023] S11, the wedge block assembly starts working. The cylinder one runs and pushes the fixed frame to make the wedge block body move downward and engage with the slider body. When the shock absorption frame at the bottom of the connecting frame two contacts the signal detection component on the bottom wall of the irregular frame, the wedge block body moves into place and the press closes the mold and maintains pressure.

[0024] Step S3 further includes the following steps:

[0025] S31. After the wedge block body is withdrawn into place, the second cylinder runs to pull the slider body. During the movement of the slider body, the sliding plate moves inside the limit frame. When another set of signal detection components inside the limit frame contacts the sliding plate, the slider body withdraws into place and the press opens the mold.

[0026] S32. When the shock-absorbing frame at the top of the connecting frame comes into contact with the signal detection component on the inner side of the top of the irregular frame, the contact sensor contacts the buffer plate, the buffer spring buffers the impact force of the collision, and the damper prevents the buffer spring from shaking continuously, reducing the damage to the signal detection component.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] 1. This invention features a wedge block assembly on the inner side of the upper mold. When the slider assembly operates, cylinder two pushes the slider body. During the movement of the slider body, the sliding plate moves inside the limiting frame. When the signal detection component inside the limiting frame contacts the sliding plate, the slider body moves into position, and the wedge block assembly starts working. Cylinder one pushes the fixing frame, causing the wedge block body to move downward and engage with the slider body. When the shock-absorbing frame at the bottom of the connecting frame two contacts the signal detection component on the bottom wall of the irregular frame, the wedge block body moves into position, and the press closes the mold and maintains pressure. This further stabilizes and limits the slider body, effectively preventing material from entering the slider hole during molding, causing the slider to jam or the slider to not form properly. It also prevents the slider from shifting laterally and ensures the molding quality of the mold.

[0029] 2. This invention features a pre-pressing mechanism on the inner side of the upper mold. The positioning pin cooperates with the upper mold to limit its movement. When the mold is closed and the material has not yet flowed to the position of the embedded insert, the pre-pressing mechanism works. The cylinder pushes the distance screw to move the pre-pressing rod downwards to press and limit the top of the embedded insert. This provides comprehensive stability to the embedded insert, preventing it from shifting due to material flow during molding and preventing material from adhering to the surface of the embedded insert, thus ensuring the stability of the molding mold during molding.

[0030] 3. The present invention has a shock-absorbing frame installed on the top of the connecting frame. When the shock-absorbing frame on the top of the connecting frame comes into contact with the signal detection component on the inner side of the top of the irregular frame, the contact sensor contacts the buffer plate. The buffer spring buffers the impact force of the collision, and the damper prevents the buffer spring from shaking continuously, thereby reducing the damage to the signal detection component, ensuring the good performance of the signal detection component, and extending the service life of the mold.

[0031] 4. This invention features a signal detection component installed inside the insertion hole. When the signal detection component is damaged, pressing the locking pin causes the moving plate to move inside the moving groove, squeezing the reset spring and causing the locking pin to disengage from the limiting hole and be located inside the moving groove. This releases the limiting relationship between the limiting frame and the connecting block, allowing the signal detection component to be disassembled from the inside of the insertion hole. Rotating the connecting ring releases the threaded connection between the connecting ring and the mounting frame, allowing the contact sensor to be disassembled. The convenient disassembly of the signal detection component facilitates maintenance and replacement by staff, improving the maintenance efficiency of the mold. Attached Figure Description

The positioning post 54 and The upper mold 2 is used to limit the upper mold 2, ensuring that the embedded insert 13 will not move in the horizontal direction. The wedge block assembly 3 works to make the cylinder 21 run to push the fixed frame 22, causing the wedge block body 23 to move downward and engage with the slider body 34. When the shock-absorbing frame 7 at the bottom of the connecting frame 25 contacts the signal detection component 6 on the bottom wall of the irregular frame 26, the wedge block body 23 moves into place. The press closes the mold and holds the pressure. After the pressing is completed, the cylinder 21 runs again to retract and pull the fixed frame 22, causing the wedge block body 23 to move upward. When the shock-absorbing frame 7 at the top of the connecting frame 24 contacts the signal detection component 6 on the inner side of the top of the irregular frame 26, the wedge block body 23 exits into place.

[0046] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 A mold for integrating multiple inserts and multiple sliders to achieve insert molding of GMT material;

[0047] The upper mold 2 includes a slider assembly 4, a slider body 34, and a pre-pressing mechanism 5. The slider assembly 4 is located on the inner side of the upper mold 2.

A connecting post 32 is mounted on the output end of the second cylinder 30, and the slider body 34 is mounted on the other end of the connecting post 32. The slider body 34 cooperates with the wedge block body 23. A limit bracket 31 is mounted on the inner wall of the upper mold 2, and a pre-pressing mechanism 5 is mounted on the outer side of the output end of the second cylinder 30. A sliding plate 33 is present and moves inside the limiting frame 31. When the slider assembly 4 operates, the second cylinder 30 pushes the slider body 34. During the movement of the slider body 34, the sliding plate 33 moves inside the limiting frame 31. When the signal detection component 6 inside the limiting frame 31 contacts the sliding plate 33, the slider body 34 moves into position. After the wedge block body 23 retracts into position, the second cylinder 30 pulls the slider body 34. During the movement of the slider body 34, the sliding plate 33 moves inside the limiting frame 31. 1. When the inner side moves, and another set of signal detection components 6 inside the limit frame 31 contacts the sliding plate 33, the slider body 34 retracts into position and the press opens the mold.

[0048] Please see Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8 A mold for integrating multiple inserts and multiple sliders to achieve insert molding of GMT material;

[0049] The system includes a signal detection component 6, a mounting frame 40, and a shock-absorbing frame 7. The signal detection component 6 is installed inside the insertion hole 53. The signal detection component 6 includes the mounting frame 40. An insertion block 41 is installed on the top of the mounting frame 40. A connecting block 42 is installed on the top of the insertion block 41. A moving groove 43 is provided on the outer side of the connecting block 42. A moving plate 44 is fitted inside the moving groove 43. A return spring 45 is installed on the inner wall of the moving groove 43, and the outer end of the return spring 45 is connected to the inner side of the moving plate 44. A locking pin 46 is installed on the outside of the mounting frame 40. The locking pin 46 engages with the inside of the limiting hole 28. A connecting ring 47 is threaded to the bottom of the mounting frame 40. A contact sensor 48 is installed at the bottom of the connecting ring 47. The signal detection component 6 is inserted into the inside of the insertion hole 53 to achieve initial fixation of the signal detection component 6. When the signal detection component 6 is damaged, the locking pin 46 is pressed. The locking pin 46 presses the moving plate 44 to move inside the moving groove 43, squeezing the reset spring 45, causing the locking pin 46 to disengage from the limiting hole 28 and be located in the moving groove 43. Inside the moving groove 43, the limiting relationship between the limiting frame 27 and the connecting block 42 is released, and the signal detection component 6 is disassembled from the inside of the insertion hole 53. The connecting ring 47 is rotated to release the threaded connection between the connecting ring 47 and the mounting frame 40, allowing the contact sensor 48 to be disassembled. This convenient disassembly of the signal detection component 6 facilitates maintenance and replacement by personnel. A shock-absorbing frame 7 is installed on the top of the connecting bracket 24. A mounting groove 49 is provided on the top of the shock-absorbing frame 7, and a damper 50 is installed inside the mounting groove 49. A buffer spring 51 is installed on the outside, and a buffer plate 52 is installed on the top of the buffer spring 51. The buffer plate 52 cooperates with the contact sensor 48. The shock-absorbing frame 7 is also installed at the bottom of the connecting frame 25, inside the limiting frame 31 and corresponding to the signal detection component 6. When the shock-absorbing frame 7 on the top of the connecting frame 24 contacts the signal detection component 6 on the inside of the top of the irregular frame 26, the contact sensor 48 contacts the buffer plate 52. The buffer spring 51 buffers the impact force of the collision, and the damper 50 prevents the buffer spring 51 from shaking continuously.

[0050] The working steps of this mold are as follows:

[0051] S1. First, the prepreg is placed into the mold. The positioning post 54 cooperates with the upper mold 2 to limit the upper mold 2, ensuring that the embedded insert 13 will not move in the horizontal direction. The slider assembly 4 works, and the cylinder 2 30 runs to push the slider body 34. During the movement of the slider body 34, the sliding plate 33 moves inside the limit frame 31. When the signal detection component 6 inside the limit frame 31 contacts the sliding plate 33, the slider body 34 moves into place.

[0052] S2. Before the mold is closed and the material has not flowed to the position of the embedded insert 13, the pre-pressing mechanism 5 works, the cylinder 36 runs to push the distance screw 37 to move the pre-pressing rod 38 downward to press and limit the top of the embedded insert 13.

[0053] S3. After the molding is completed, cylinder 21 retracts and pulls the fixed frame 22 to move the wedge block body 23 upward. When the shock-absorbing frame 7 at the top of the connecting frame 24 contacts the signal detection component 6 on the inner side of the top of the irregular frame 26, the wedge block body 23 exits into place.

[0054] S4. When the signal detection component 6 is damaged, press the locking post 46. The locking post 46 presses the moving plate 44 to move inside the moving groove 43 and squeeze the reset spring 45, causing the locking post 46 to disengage from the limiting hole 28 and be located inside the moving groove 43. Release the limiting relationship between the limiting frame 27 and the connecting block 42, disassemble the signal detection component 6 from the inside of the insertion hole 53, rotate the connecting ring 47 to release the threaded connection between the connecting ring 47 and the mounting frame 40, and repair and replace the contact sensor 48.

[0055] Step S1 also includes the following steps:

[0056] S11, the wedge block assembly 3 starts to work, the cylinder 21 runs to push the fixed frame 22, causing the wedge block body 23 to move downward and engage with the slider body 34. When the shock-absorbing frame 7 at the bottom of the connecting frame 25 contacts the signal detection assembly 6 on the bottom wall of the irregular frame 26, the wedge block body 23 moves into place, and the press closes the mold and maintains pressure.

[0057] Step S3 also includes the following steps:

[0058] S31. After the wedge block body 23 is withdrawn into place, the cylinder 2 30 runs to pull the slider body 34. During the movement of the slider body 34, the sliding plate 33 moves inside the limit frame 31. When the other set of signal detection components 6 inside the limit frame 31 contacts the sliding plate 33, the slider body 34 is withdrawn into place and the press opens the mold.

[0059] When the shock-absorbing frame 7 at the top of the connecting frame 24 contacts the signal detection component 6 on the inner side of the top of the irregular frame 26, the contact sensor 48 contacts the buffer plate 52. The buffer spring 51 buffers the impact force of the collision, and the damper 50 prevents the buffer spring 51 from shaking continuously, reducing the damage to the signal detection component 6.

[0060] Working principle: When using this device, the prepreg is first placed into the mold. The positioning pin 54 cooperates with the upper mold 2 to limit the upper mold 2, ensuring that the embedded insert 13 will not move in the horizontal direction. The slider assembly 4 works, and the cylinder 2 30 runs to push the slider body 34. During the movement of the slider body 34, the sliding plate 33 moves inside the limit frame 31. When the signal detection component 6 inside the limit frame 31 contacts the sliding plate 33, the slider body 34 moves into place. The wedge block assembly 3 starts to work, and the cylinder 1 21 runs to push the fixed frame 22, causing the wedge block body 23 to move downward and slide. When the shock-absorbing frame 7 at the bottom of the connecting frame 25 contacts the signal detection component 6 on the bottom wall of the irregular frame 26, the wedge-tightening block body 23 moves into place, the press closes the mold and holds pressure. Before the mold is closed and the material has not flowed to the position of the embedded insert 13, the pre-pressing mechanism 5 works, the cylinder 36 runs and pushes the distance screw 37 to move the pre-pressing rod 38 downward to press and limit the top of the embedded insert 13. After the pressing is completed, the cylinder 21 runs again and retracts to pull the fixing frame 22 to move the wedge-tightening block body 23 upward. When the shock-absorbing frame 7 at the top of the connecting frame 24 contacts the irregular frame 26, the wedge-tightening block body 23 moves into place. When the signal detection component 6 on the top inner side contacts, the wedge block body 23 retracts into place. After the wedge block body 23 retracts into place, the cylinder 2 30 moves to pull the slider body 34. During the movement of the slider body 34, the sliding plate 33 moves inside the limit frame 31. When another set of signal detection components 6 inside the limit frame 31 contacts the sliding plate 33, the slider body 34 retracts into place and the press opens the mold. When the shock-absorbing frame 7 on the top of the connecting frame 1 24 contacts the signal detection component 6 on the top inner side of the irregular frame 26, the contact sensor 48 contacts the buffer plate 52. The buffer spring 51 buffers the impact force of the collision. The damper 50 prevents the buffer spring 51 from shaking continuously, reducing damage to the signal detection component 6. When the signal detection component 6 is damaged, the locking post 46 is pressed, and the locking post 46 presses the moving plate 44 to move inside the moving groove 43, squeezing the reset spring 45, causing the locking post 46 to disengage from the limiting hole 28 and be located inside the moving groove 43, releasing the limiting relationship between the limiting frame 27 and the connecting block 42, disassembling the signal detection component 6 from the inside of the insertion hole 53, rotating the connecting ring 47 to release the threaded connection between the connecting ring 47 and the mounting frame 40, and inspecting and replacing the contact sensor 48.
