Abstract
Description
Technical Field
[0001] This solution belongs to the field of molding dies, specifically involving a molding die for processing electronic parts that facilitates demolding. Background Technology
[0002] Electronic component manufacturing refers to the process of transforming raw materials into electronic components using various technological methods. These components include resistors, capacitors, inductors, diodes, transistors, integrated circuits, etc., which are the basic building blocks of electronic devices and systems.
[0003] A search revealed a utility model patent application with publication number CN217252528U, which discloses a rapid prototyping mold for precision electronic components. Specifically, it relates to the field of precision electronic component processing technology. Existing molding dies lack corresponding clamping devices, or some clamping devices have overly simple structures, resulting in poor part stability and easy deviations during processing. Furthermore, the mold's instability during mold closing can lead to misalignment, affecting part processing. The proposed solution includes a processing table with a clamping mechanism and a processing mechanism. The clamping mechanism includes a support plate fixedly mounted on the surface of the processing table away from the processing mechanism. A servo motor is fixedly mounted on the support plate, and a first synchronous pulley is fixedly mounted on the output end of the servo motor. The clamping mechanism effectively clamps the parts, improving their stability and preventing positional displacement due to force during processing, thus improving processing efficiency.
[0004] Currently, when processing electronic components, especially electronic chips, the chip substrate is placed in a mold and then mounted by a robotic arm. Then, the chip is pressed together using ordinary pressing or thermoforming. However, most chips are embedded in the mold groove after pressing, which is inconvenient when unloading. Furthermore, different types of electronic components require different molds, and the mold shapes and lifting and demolding structures are also different. Therefore, it is necessary to design a universal demolding and pushing drive structure to facilitate use with different molds and lifting and demolding structures. Utility Model Content
[0005] The purpose of this solution is to provide a molding die for electronic parts that facilitates demolding, in order to solve the problem that electronic parts become embedded in the mold groove after pressing and are difficult to remove. At the same time, different molds use different demolding structures, so a unified demolding push-drive structure needs to be designed.
[0006] To achieve the above objectives, this solution provides a molding die for easy demolding of electronic components, including a base, a mold mechanism on top of the base, the mold mechanism including a platform, a channel in the middle of the platform, a mold table on top of the platform, a plurality of mold slots on the upper end of the mold table, an inner cavity inside the mold table, an ejector hole at the bottom of the mold slot, an ejector rod penetrating through the ejector hole, a common ejector plate fixed to the lower ends of the plurality of ejector rods, an inner sleeve fixedly penetrating through the bottom of the inner cavity, a lifting rod slidably sleeved inside the inner sleeve, the upper end of the lifting rod fixed to the lower end of the ejector plate, a spring wound around the surface of the lifting rod, the two ends of the spring being fixedly assembled to the end faces of the ejector plate and the inner sleeve respectively, the lower end of the lifting rod extending downward through the inner sleeve, and a connecting seat fixed at the end, a cylinder fixed inside the channel, a piston rod for extension and retraction inside the cylinder, the end of the piston rod slidingly inserted into and connected to the connecting seat.
[0007] The principle of this solution is as follows: This solution uses a cylinder to drive an ejector rod to achieve automatic demolding of electronic components. After pressing is completed, the piston rod of cylinder one moves upward, pushing the connecting seat and lifting rod upward, causing the ejector plate to rise synchronously. The ejector plate is fixedly connected to multiple ejector rods, so that all ejector rods extend from the ejector holes at the bottom of the mold groove, ejecting the electronic components embedded in the groove and completing demolding. After demolding, the piston rod of cylinder one retracts. At this time, the elastic restoring force of the spring causes the lifting rod to reset, and the ejector rod retracts into the mold groove to prepare for the next pressing. The two ends of the spring are fixed to the ejector plate and the inner sleeve respectively to ensure accurate return of the ejector rod and avoid jamming. In addition, the sliding fit between the inner sleeve and the lifting rod ensures the stability of the movement, while the plug-in design of the connecting seat and the piston rod facilitates power transmission and separation, realizing efficient cyclic operation.
[0008] The technical advantages of this solution are as follows: through the linkage design of the ejector rod, ejector plate and cylinder, the parts can be quickly ejected from the mold slot after processing, which significantly improves the demolding efficiency. The spring-assisted reset mechanism ensures that the ejector rod returns to its position accurately and avoids jamming. It is especially suitable for batch processing of electronic parts, reducing manual part removal time and reducing the risk of damage.
[0009] The mold table adopts a detachable structure, and can be quickly locked or replaced with the base through threaded pillars, collars and threaded caps, adapting to different mold slot types.
[0010] Furthermore, extension platforms are fixed at both ends of the base, and the extension platforms are symmetrically distributed along both ends of the base. Threaded columns are fixed at the upper ends of the extension platforms. Through the arrangement on both sides, the overall stable connection can be ensured after the base and the mold platform are connected.
[0011] Furthermore, a collar is slidably fitted onto the surface of the threaded column. The outer ring wall of the collar is fixedly assembled with the surface of the mold table via a bracket. The threaded column and the collar are installed together to achieve stable and rapid docking between the base and the mold table.
[0012] Furthermore, the upper end of the threaded column is threaded with a threaded cap, the end face of which is tightly fitted against the end face of the collar, so that it can be locked and fixed after the base and the mold table are connected.
[0013] Furthermore, a pressing mechanism is also provided above the base. The pressing mechanism includes a second cylinder, and a second piston rod for extension and retraction is provided inside the second cylinder. The upper ends of the two second piston rods are fixed to the same support plate. The extension and retraction of the second piston rod of the second cylinder can realize the lifting and lowering adjustment of the entire pressing mechanism.
[0014] Furthermore, a cylinder three is fixedly installed inside the support plate, and a piston rod three for telescopic movement is installed inside the cylinder three. A heat insulation seat is fixed to the end of the two piston rods three. The heat insulation seat is made of ceramic material. The telescopic movement of the piston rods three of the cylinder three can ensure the stable up and down movement of the pressing plate.
[0015] Furthermore, a pressing plate is fixed inside the heat insulation seat, and several electric heating tubes are inserted and fixed inside the pressing plate. The electric heating tubes can be powered on or off as needed. When powered on, the pressing plate can form a heat-pressed structure. Attached Figure Description

[0020] The following detailed explanation illustrates the specific implementation methods:
[0021] The reference numerals in the accompanying drawings include: base 1, mold mechanism 2, base 20, channel 21, mold table 22, mold groove 23, inner cavity 24, ejector hole 25, ejector rod 26, ejector plate 27, inner sleeve 201, lifting rod 202, spring 203, connecting seat 204, cylinder one 205, extension table 2001, threaded column 2002, collar 2003, threaded cap 2004, pressing mechanism 3, cylinder two 30, support plate 31, cylinder three 32, heat insulation seat 33, and pressing plate 34. Detailed Implementation
[0022] The basic implementation examples are as follows: Figures 1-4As shown: A molding die for easy demolding of electronic components includes a base 1, a mold mechanism 2 above the base 1, and a base platform 20. A channel 21 is provided in the middle of the base platform 20, which can support different types of mold platforms 22. The channel 21 provides sufficient space for the placement of a cylinder 205. A mold platform 22 is also provided above the base platform 20. Several mold slots 23 are formed at the upper end of the mold platform 22, which can hold the substrate awaiting pressing. An inner cavity 24 is formed inside the mold platform 22. An ejector hole 25 is formed at the bottom of the mold slot 23. An ejector rod 26 is inserted through the ejector hole 25, and the ejector rod 26 can cooperate with the ejector hole 25 to achieve through-movement. When material needs to be discharged, the ejector rod 26 can extend upward through the ejector hole 25 to eject the machined parts from the mold slot 23, facilitating the discharge of electronic components. Several ejector rods 26 have their lower ends fixed to the same ejector plate 27, which can drive the ejector rods 26 to move synchronously. An inner sleeve 201 is fixedly inserted through the bottom of the inner cavity 24. A lifting rod 202 is slidably connected inside the inner sleeve 201. The upper end of the lifting rod 202 is fixed to the lower end of the ejector plate 27. A spring 203 is wound around the surface of the lifting rod 202. The spring 203 ensures the return capability of the lifting rod 202 after extension and retraction relative to the inner sleeve 201. That is, after the ejector rod 26 ejects material, the piston rod of cylinder 205 retracts. The connector 204 is a plug-in type, so when the piston rod retracts, the reset effect of 203 is needed to retract the ejector rod 26 to ensure structural integrity. The two ends of the spring 203 are fixedly assembled to the end faces of the ejector plate 27 and the inner sleeve 201, respectively. The lower end of the lifting rod 202 extends downward through the inner sleeve 201 and is fixed to the connector 204 at its end. A cylinder 205 is fixed inside the channel 21, and a piston rod for extension and retraction is installed inside the cylinder 205. The end of the piston rod slides into and engages with the connector 204. The advancement of the piston rod in the cylinder 205, through the combined upward movement of all components, allows the ejector rod 26 to eject the electronic components embedded in the mold groove 23 after pressing. The base 20... Extension platforms 2001 are fixed at both ends of the base 20, symmetrically distributed along both ends. A threaded post 2002 is fixed to the upper end of each extension platform 2001. This arrangement on both sides ensures stable docking of the base 20 and the mold platform 22. A collar 2003 is slidably fitted onto the surface of the threaded post 2002. The outer ring of the collar 2003 is fixedly assembled to the surface of the mold platform 22 via a bracket. The mating of the threaded post 2002 and the collar 2003 enables stable and rapid docking of the base 20 and the mold platform 22. A threaded cap 2004 is threadedly connected to the upper end of the threaded post 2002. The end face of the threaded cap 2004 is tightly fitted against the end face of the collar 2003, ensuring stable docking of the base 20 and the mold platform 22 after docking.Secure by locking.
[0023] like Figure 1 As shown, a pressing mechanism 3 is also provided above the base 1. The pressing mechanism 3 includes a second cylinder 30. The second cylinder 30 has a second piston rod for extension and retraction inside. The upper ends of the two second piston rods are fixed to the same support plate 31. The support plate 31 is fixed through the inside of the third cylinder 32. The third cylinder 32 has a third piston rod for extension and retraction inside. The ends of the two third piston rods are fixed to a heat insulation seat 33. The heat insulation seat 33 is made of ceramic material. The heat insulation seat 33 supported by ceramic material can prevent heat from being transferred to the position of the third cylinder 32 when the pressing plate 34 is hot-pressed after the electric heating tube 35 is heated. The pressing plate 34 is fixed inside the heat insulation seat 33. Several electric heating tubes 35 are inserted and fixed through the pressing plate 34. By extending and retracting the second piston rod of the second cylinder 30, the overall lifting and lowering adjustment of the pressing mechanism 3 can be realized. The extension and retraction of the third piston rod of the third cylinder 32 can ensure the stable contact and pressing process between the pressing plate 34 and the electronic components.
[0024] The specific implementation process of this utility model is as follows: This solution uses cylinder 205 to drive the ejector rod 26 to achieve automatic demolding of electronic components. After pressing is completed, the piston rod of cylinder 205 moves upward, pushing the connecting seat 204 and the lifting rod 202 upward, causing the ejector plate 27 to rise synchronously. The ejector plate 27 is fixedly connected to multiple ejector rods 26, so that all ejector rods 26 extend from the ejector hole 25 at the bottom of the mold groove 23, ejecting the electronic components embedded in the groove, completing the demolding. After demolding, cylinder 205... When piston rod 5 retracts, the elastic restoring force of spring 203 causes lifting rod 202 to reset, and top rod 26 retracts into top hole 25 to prepare for the next pressing operation. The two ends of spring 203 are fixed to top plate 27 and inner sleeve 201 respectively to ensure accurate return of top rod 26 and avoid jamming. In addition, the sliding fit between inner sleeve 201 and lifting rod 202 ensures the stability of movement, while the plug-in design of connecting seat 204 and piston rod 1 facilitates power transmission and separation, realizing efficient cyclic operation.
[0025] The mold platform 22 is modularly assembled with the base platform 20 through the extension platform 2001, the threaded post 2002 and the collar 2003. During installation, the mold platform 22 is sleeved on the threaded post 2002 through the collar 2003 and tightened with the threaded cap 2004 to ensure that the collar 2003 and the end face of the threaded cap 2004 fit tightly together, ensuring that the mold platform 22 is horizontal and stable.
[0026] The pressing mechanism 3 achieves precise pressing through the coordinated action of cylinder 2 30 and cylinder 3 32. The piston rod 2 of cylinder 2 30 adjusts the height of the support plate 31 and initially positions the pressing plate 34. The piston rod 3 of cylinder 3 32 controls the fine-tuning pressing force of the pressing plate 34 to ensure uniform force on the electronic components. The pressing plate 34 has a built-in electric heating tube 35, which heats and then hot-presses the substrate in the mold groove 23. The heat insulation seat 33 is made of ceramic material, which effectively blocks heat from being conducted to cylinder 3 32, avoiding high temperature from affecting the performance of pneumatic components. During the pressing process, the rigid connection between the heat insulation seat 33 made of ceramic material and the pressing plate 34 ensures the stability of force transmission and reduces heat loss. After pressing is completed, cylinder 3 32 retracts first to release pressure, and cylinder 2 30 then lifts the pressing plate 34 to reset, forming a staged demolding process to prevent parts from sticking together.
