Description

Technical Field

[0001] This utility model relates to the field of injection molding technology, and in particular to a mold release needle punching component. Background Technology

[0002] For PVC and silicone products, the demolding process after injection molding has always been a critical step in production. Traditionally, this process has been highly manual, requiring workers to use tools (such as fine needles) to pick out the finished products one by one from the mold.

[0003] This manual demolding method has many drawbacks: First, it greatly limits the efficiency and capacity of the production line because the speed of manual demolding is much lower than the molding cycle of the machine; second, the long-term repetitive picking action is labor-intensive for workers and easily leads to fatigue, which in turn affects the accuracy of operation and causes scratches, deformation or damage to the product surface, especially for some products with complex structures or thin walls, the damage rate is even higher; third, due to the randomness and instability of manual operation, it is difficult to guarantee the consistency of product quality between different batches or even within the same batch, which seriously affects the product qualification rate and the company's production costs.

[0004] As the manufacturing industry increasingly demands automation and lean production, overcoming the challenges posed by traditional manual demolding methods and achieving efficient, stable, and non-destructive product demolding and removal has become a pressing technical challenge in the PVC and silicone product manufacturing industry, thus necessitating improvements.

[0038] The present invention will now be described in detail with reference to the accompanying drawings.

[0039] like Figures 1 to 3 As shown, a mold-removing needle punching assembly of the present invention includes a base plate 1, a needle 2, a mold-removing driver 3, an air-blowing chuck 4, and a displacement driver 5.

[0040] One end of the substrate 1 is provided with a mold release station 11; the mold release station 11 provides a standardized operating space for the product demolding process, which facilitates the subsequent precise operation of components such as the piercing needle 2 and the air blowing chuck 4 on the product at the mold release station 11, ensuring the accuracy and orderliness of the demolding operation.

[0041] The needle 2 is rotatably disposed at one end of the substrate 1, so that the needle 2 is rotatably connected to the substrate 1. When demolding is required, the needle 2 can extend into the demolding station 11 to pierce the product and assist the product in leaving the mold; when the needle 2 is not required to operate, it can exit the demolding station 11 and separate from the product.

[0042] The mold release driver 3 is disposed on the substrate 1 and is used to drive the needle 2 to extend into the mold release station 11 to insert into the product or to exit the mold release station 11 to separate from the product. It precisely controls the movement of the needle 2 so that the needle 2 can insert into the product at the appropriate time, making it easier to lift the product and separate it from the mold, thus helping the product to be demolded smoothly. The mold release driver 3 drives the needle 2 to exit the mold release station 11 and separate from the product, avoiding the inefficiency of manually picking out products with tools, improving the efficiency and capacity of the production line. At the same time, it reduces the scratches, deformation or breakage of the product surface caused by manual operation, reduces the product damage rate and improves the product qualification rate.

[0043] The air-blowing chuck 4 is positioned above the mold-lifting station 11 and is used for blowing air and clamping products. The air-blowing operation of the air-blowing chuck 4 helps the product to smoothly leave the mold, reduces the adhesion between the product and the mold, and, together with the clamping function, enables the product to be quickly and stably removed, further improving production efficiency. Compared with manual operation, it can better ensure the consistency of product quality and reduce the production cost of enterprises.

[0044] The displacement actuator 5 is located on the demolding actuator 3 and is used to drive the displacement of the air-blowing chuck 4. The displacement actuator 5 provides displacement power to the air-blowing chuck 4, enabling it to perform air-blowing and clamping operations at appropriate positions. This allows the air-blowing chuck 4 to accurately position itself to the product, adapting to the part-removal requirements of products in different locations, further enhancing the flexibility and automation of the assembly, and ensuring efficient, stable, and damage-free product demolding and removal. Specifically, the displacement actuator 5 drives the air-blowing chuck 4 to press against the product close to the substrate 1 to clamp the product, and the displacement actuator 5 drives the air-blowing chuck 4 away from the substrate 1 to release the product.

[0045] The working principle is as follows: the ejector pin assembly is fixed to an external robotic arm, which drives the ejector pin assembly to move. The mold is set at the ejector station 11. When the product needs to be demolded after injection molding, the ejector driver 3 starts working. The ejector driver 3 provides power to drive the pin 2 to extend into the ejector station 11 and pierce the product. The external robotic arm drives the ejector pin assembly to rise a certain distance, and the product edge is removed from the mold under the action of the pin 2. At this time, the displacement driver 5 provides displacement power to the air-blowing chuck 4. According to the actual position of the product and the demolding situation, the position of the air-blowing chuck 4 is precisely adjusted so that the air-blowing chuck 4 can accurately align with the edge of the product that has left the mold. Subsequently, the air-blowing chuck 4 blows air through an external pressurization device to completely separate the product from the mold. The displacement driver 5 drives the air-blowing chuck 4 again to press against the product and move it close to the substrate 1, so that the product is clamped between the air-blowing chuck 4 and the substrate 1. An external robotic arm drives the demolding needle assembly to a preset position. The demolding driver 3 drives the needle 2 to exit the demolding station 11 and separate from the product. At the same time, the displacement driver 5 drives the air chuck 4 away from the substrate 1 to release the product. The product falls under the action of gravity, thus completing the product demolding and removal process.

[0046] like Figure 2 As shown, in this embodiment, a rotating shaft 12 is provided at one end of the substrate 1, and a first rotating hole 21 is provided on the needle 2. The first rotating hole 21 is rotatably connected to the rotating shaft 12.

[0047] The needle 2 rotates around the shaft 12 by the cooperation of the rotating hole and the rotating shaft 12, so that the needle 2 can flexibly extend into the mold release station 11 to insert into the product to assist in demolding, and exit the mold release station 11 to separate from the product. This overcomes the problems of low efficiency, easy damage to the product and poor quality consistency of manual demolding, and achieves efficient, stable and damage-free demolding.

[0048] like Figure 2 As shown, the needle 2 in this embodiment is provided with a second rotating hole 22, and a rotating shaft 23 is rotatably provided in the second rotating hole 22; so that the needle 2 can use the rotating shaft 23 as the power connection fulcrum.

[0049] The mold-lifting driver 3 is equipped with a connector 31, one end of which is fixed to the mold-lifting driver 3, and the other end of which is rotatably connected to the rotating shaft 23. The mold-lifting driver 3 can be a cylinder, an electric cylinder, or a linear motor. In this embodiment, a cylinder is used as an example of the mold-lifting driver 3.

[0050] The power transmission and rotational connection between the mold release driver 3 and the needle 2 are established through the connector 31. The mold release driver 3 can accurately drive the needle 2 to rotate around the rotating shaft 23, thereby enabling the needle 2 to insert into the mold release station 11 to pierce the product or to exit the mold release station 11 and separate from the product. This overcomes the drawbacks of low efficiency, high labor intensity and poor product quality consistency of manual demolding, and achieves efficient, stable and non-destructive demolding.

[0051] like Figure 2 As shown, the connector 31 in this embodiment includes a first connecting part 311, a rotating rod 312, and a second connecting part 313; thus constructing a segmented connecting structure, which facilitates flexible connection and motion transmission between different components.

[0052] The first connecting part 311 is connected to the rotating shaft 23; the connection between the connector 31 and the needle 2 provides a basis for the subsequent rotation of the needle 2, and facilitates the power transmission of the mold release driver 3 to the needle 2.

[0053] The rotating rod 312 is rotatably positioned between the first connecting part 311 and the second connecting part 313. Through the rotational characteristics of the rotating rod 312, the relative position between the first connecting part 311 and the second connecting part 313 can be flexibly changed, allowing the connector 31 to adapt to the angle changes during the rotation of the needle 2 and ensuring the stability of power transmission.

[0054] The second connecting part 313 is connected to the output end of the mold release driver 3. The connection between the connector 31 and the mold release driver 3 enables the mold release driver 3 to precisely drive the needle 2 to enter the mold release station 11 to insert into the product or to exit the mold release station 11 and separate from the product.

[0055] like Figure 2 As shown, the substrate 1 of this embodiment is provided with at least two sets of guide rollers 13, and the surface of the second connecting portion 313 abuts against the two sets of guide rollers 13. The guide rollers 13 provide support and guidance for the second connecting portion 313, and the rolling characteristics of the guide rollers 13 reduce friction. The two sets of guide rollers 13 form a clamping and guiding effect on the second connecting portion 313, so that the second connecting portion 313 can move smoothly and steadily during the driving process of the mold release driver 3.

[0056] like Figure 2 and Figure 3 As shown, the displacement actuator 5 in this embodiment includes a tilting actuator 51 and a translation actuator 52; the displacement action of the air chuck 4 is decomposed into two movements in the tilting and translation directions to meet the position adjustment requirements of the air chuck 4 under different demolding scenarios. The tilting actuator 51 and the translation actuator 52 are both cylinders, electric cylinders, or linear motors. This embodiment uses cylinders as an example where both the tilting actuator 51 and the translation actuator 52 are cylinders.

[0057] The mold-lifting driver 3 is provided with a fixed frame 32 and a rotating frame 33. The fixed frame 32 is fixed to the mold-lifting driver 3, and one end of the rotating frame 33 is rotatably connected to the fixed frame 32. The rotatable connection between one end of the rotating frame 33 and the fixed frame 32 provides a rotation fulcrum for the tilting driver 51, so that the rotating frame 33 can rotate relative to the fixed frame 32, which is the basis for adjusting the position of the air-blowing chuck 4 in the tilting direction.

[0058] Both the tilting actuator 51 and the translation actuator 52 are fixed to the rotating frame 33. The output end of the tilting actuator 51 is provided with a rotating connector 53, which is rotatably connected to the fixed frame 32. When the tilting actuator 51 is working, it pushes the rotating frame 33 to rotate around the connection point with the fixed frame 32 through the rotating connector 53, thereby driving the translation actuator 52 and the air chuck 4 to achieve tilting displacement. The fixed frame 32 and the rotating frame 33 are rotatably connected by a pivot pin.

[0059] The output of the translation driver 52 is connected to the air chuck 4. This allows the translation driver 52 to directly drive the air chuck 4 to perform linear translational motion, enabling the air chuck 4 to move precisely in the horizontal direction.

[0060] like Figure 3 As shown, the air-blowing chuck 4 in this embodiment is provided with a guide rail 41, and the translation driver 52 is provided with a guide groove 521. The guide rail 41 and the guide groove 521 are slidably connected. Through the slidable connection between the guide rail 41 and the guide groove 521, the air-blowing chuck 4 can move stably along the direction set by the guide groove 521 under the drive of the translation driver 52, ensuring that the air-blowing chuck 4 does not deviate during the translation process, accurately reaching the designated position to pick up the product, overcoming the problems of product position deviation and inconsistent quality caused by unstable operation during manual demolding, and achieving efficient, stable, and accurate non-destructive demolding.

[0061] like Figure 2 and Figure 3 As shown, the rotating connector 53 in this embodiment includes a connecting rod 531 and a rotating plate 532. The output end of the rocker actuator 51 is connected to the connecting rod 531. By connecting the output end of the rocker actuator 51 to the connecting rod 531, the power generated by the rocker actuator 51 is transmitted to the connecting rod 531, providing a power basis for subsequently driving the rotating plate 532 to move.

[0062] One end of the rotating plate 532 is rotatably connected to the connecting rod 531, so that the rotating plate 532 can rotate relative to the connecting rod 531, thereby changing the direction of the force.

[0063] The other end of the rotating plate 532 is rotatably connected to the fixed frame 32. The rotatable connection between the rotating plate 532 and the fixed frame 32 converts the power transmitted from the connecting rod 531 into the tilting motion of the rotating frame 33 around the fixed frame 32, thereby driving the translation driver 52 and the air chuck 4 to achieve precise tilting displacement.

[0064] like Figure 3 As shown, the air blowing chuck 4 in this embodiment is provided with an air channel 42 inside. An air blowing hole 43 is provided at one end of the air channel 42 near the mold release station 11. The air channel 42 is provided with an air blowing connector 44 that is connected to an external pressurization device.

[0065] A dedicated gas transmission channel is constructed through the air passage 42, allowing the gas supplied by the external pressurization device to flow orderly inside the air chuck 4; ensuring that the gas can be accurately guided to the designated position, providing a stable channel foundation for subsequent air blowing operations.

[0066] An air blowing hole 43 is provided at one end of the air passage 42 near the mold release station 11, so that the air passage 42 has an air blowing hole 43 at a specific position, allowing the gas flowing in the air passage 42 to be sprayed out in a concentrated and directional manner; so that the gas directly acts on the product on the mold release station 11, and the airflow effectively reduces the adhesion between the product and the mold, helping the product to be smoothly released from the mold.

[0067] By using the air blowing connector 44, a connection bridge is established between the air passage 42 and the external pressurization equipment, allowing the gas generated by the external pressurization equipment to smoothly enter the air passage 42; providing sufficient and stable air source power for the entire blowing process, ensuring the continuity and effectiveness of the blowing operation, and thus improving the efficiency and quality of product demolding.

[0068] like Figure 2 As shown, in this embodiment, a protective member 14 is provided at one end of the substrate 1 near the mold release station 11. The protective member 14 is provided with a through hole 141. The needle 2 extends through the through hole 141 to pierce the product or exit the mold release station 11 and separate from the product.

[0069] The protective component 14 provides protection and limits the activity area of ​​the needle 2 during its extension and retraction, preventing the needle 2 from being damaged by external interference or accidental contact when it is not in operation, and also avoiding adverse effects such as scratching of surrounding components during the extension and retraction of the needle 2.

[0070] The through-hole 141 provides a channel for the extension and retraction of the needle 2, allowing the needle 2 to extend through the through-hole 141 according to a predetermined movement trajectory to pierce the product and assist in demolding, or to exit the demolding station 11 and separate from the product after completing the demolding action. This ensures the stability and safety of the needle 2 during its operation, ensures the smooth progress of the entire demolding process, overcomes the problems that may exist in manual demolding or ordinary demolding devices, such as easy damage to the needle 2 and inaccurate movement, and achieves efficient, stable and damage-free demolding operation.

[0071] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
