Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mold manufacturing, in particular to a combined inclined ejector core pulling mechanism. Background Art
[0002] In the field of mold manufacturing, the performance of the core pulling mechanism plays a crucial role in product quality and production efficiency. Currently, most core pulling mechanisms use air cylinders for core pulling operations. However, there are many drawbacks that cannot be ignored in the actual application of air cylinders.
[0003] The working principle of the air cylinder relies on pneumatic drive, which makes its stability poor. The instability of the air pressure easily causes large fluctuations in the speed and force of the air cylinder during the telescopic process, thereby resulting in uneven core pulling actions and seriously affecting the accuracy and effect of core pulling. For example, in some molds with extremely high dimensional accuracy requirements, the core pulling driven by the air cylinder may cause local dimensional deviations of the product and cannot meet the strict quality standards.
[0004] Secondly, after long-term use, various faults are likely to occur in the air cylinder. Since the seals inside the air cylinder are prone to aging and wear, air leakage frequently occurs. This not only requires frequent replacement of seals and maintenance of the air cylinder, increasing the maintenance cost and workload, but also may suddenly malfunction during the production process, affecting normal production.
[0005] In addition, it is difficult to arrange the air cylinder in a complex mold structure. Due to the structural characteristics and size limitations of the air cylinder itself, it may interfere with other components inside the mold with limited space, affecting the overall design and space utilization of the mold.
[0006] Moreover, the air cylinder is prone to jitter during operation, and this jitter will further exacerbate the instability of the core pulling action, increasing the risk of product defects and also accelerating the wear and damage of the air cylinder.
[0007] Therefore, we propose a combined inclined ejector core pulling mechanism. Content of the Utility Model
[0008] To solve the above technical problems, the utility model provides a combined inclined ejector core pulling mechanism.
[0009] The utility model adopts the following technical solutions to realize a combined inclined ejector core pulling mechanism, including a mechanism base. A core pulling motion component is arranged on the top of the mechanism base. A detachable connection structure is connected to the right side wall of the core pulling motion component. Sliding wheel structures are arranged at the top and inside of the mechanism base near the right side. An adjustable driving structure is also arranged inside the mechanism base. A steel wire rope body is arranged between the adjustable driving structure and the core pulling motion component and the sliding wheel structure.
[0010] As a further improvement of the above solution, the core-pulling movement assembly includes a movement frame, a movement groove is formed inside the movement frame, sliding grooves are formed on the front and back sides of the movement groove, and a clamping member mounting seat is arranged inside the movement groove.
[0011] As a further improvement of the above solution, a plurality of rolling wheels are connected to the front and back sides of the clamping member mounting seat, and the plurality of rolling wheels are all installed in the sliding groove and can move along the sliding groove. An installation groove is formed on the left side wall of the clamping member mounting seat, and a plurality of four-corner installation grooves are further formed outside the installation groove.
[0012] As a further improvement of the above solution, the detachable connection structure includes a first fixing plate, a lifting seat is fixedly connected to the right side wall of the first fixing plate, a second fixing plate is fixedly connected to the right side wall of the lifting seat, a movable seat is connected to the right side of the second fixing plate by bolts, and a wire rope connecting member is fixedly connected to the right side wall of the movable seat.
[0013] As a further improvement of the above solution, the sliding wheel structure includes two installation side seats, a sliding wheel body is arranged between the two installation side seats, and the sliding wheel body and the two installation side seats are both connected by a rotating shaft.
[0014] As a further improvement of the above solution, the adjustable driving structure includes a first mounting seat, a driving wheel structure is arranged on the top of the first mounting seat, a driven turntable is connected to the front of the driving wheel structure by a rotating shaft, and a driving turntable is connected to the front of the driven turntable by bolts.
[0015] As a further improvement of the above solution, the adjustable driving structure further includes a driving motor, the bottom of the driving motor is fixedly connected with a second mounting seat, and the driving motor can be detached from the mechanism base through the second mounting seat, so as to adjust the position of the driving motor.
[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0017] In the present utility model, the driving mode of the adjustable driving structure, the core-pulling movement assembly, the detachable connection structure, the wire rope body plus the sliding wheel structure brings significant all-round improvement to the core-pulling mechanism.
[0018] First of all, there is a great improvement in the core-pulling accuracy. The combination of the wire rope body and the sliding wheel structure can ensure that the driving force is uniform and controllable, making the core-pulling fixture move smoothly and precisely, avoiding defects and flaws caused by uneven core-pulling, and improving the product qualification rate and reliability.
[0019] Secondly, the maintenance cost is significantly reduced. The wire rope body and sliding wheel have a simple and strong structure and are more durable than gas rods. During long-term use, the company does not need to frequently repair and replace parts, which reduces operating costs, improves equipment utilization, and ensures continuous and stable production.
[0020] Then, the flexibility of mold design is enhanced, and the compact layout of the wire rope body and the sliding wheel structure can be integrated into the complex mold structure to avoid interference with other components. Under the trend of lightweight and thin consumer electronic products, this driving method can achieve efficient core pulling in a limited space, support lightweight product design, and enhance product competitiveness.
[0021] Finally, since the driving wheel structure within the adjustable driving structure is replaceable, the accuracy can be flexibly adjusted according to different production requirements. In production that requires high precision, a high-precision pulley can be selected, and in production that has relatively low precision requirements, a lower-cost pulley can be selected, thereby achieving the best balance between cost and accuracy.

[0029] Next, in combination with the accompanying drawings and specific embodiments, the present utility model will be further described. It should be noted that on the premise of no conflict, any combination of the following-described embodiments or technical features can form a new embodiment.
[0030] Embodiment:
[0031] Please refer to Figures 1-5 , a combined inclined lifter core-pulling mechanism of this embodiment includes a mechanism base 1. A core-pulling motion component 2 is provided on the top of the mechanism base 1. A detachable connection structure 3 is connected to the right side wall of the core-pulling motion component 2. Sliding wheel structures 4 are provided on the top of the mechanism base 1 near the right side and inside the mechanism base 1 near the right side. An adjustable driving structure 5 is further provided inside the mechanism base 1. A steel wire rope body 6 is provided between the adjustable driving structure 5, the core-pulling motion component 2 and the sliding wheel structure 4.
[0032] The driving method using the adjustable driving structure 5, the core-pulling motion component 2, the detachable connection structure 3, the steel wire rope body 6 and the sliding wheel structure 4 has brought significant improvements in all aspects to the core-pulling mechanism.
[0033] First of all, there is a great improvement in the core-pulling accuracy. The combination of the steel wire rope body 6 and the sliding wheel structure 4 can ensure that the driving force is uniform and controllable, making the core-pulling fixture move smoothly and precisely, avoiding defects and flaws caused by uneven core-pulling, and improving the product qualification rate and reliability.
[0034] Secondly, the maintenance cost is significantly reduced. The steel wire rope body 6 and the sliding wheel structure 4 are simple and strong, and their durability is better than that of the air rod. During long-term use, enterprises do not need to frequently repair and replace parts, reducing the operation cost, improving the equipment utilization rate, and ensuring the continuous and stable production.
[0035] Then, the flexibility of the mold design is enhanced. The compact layout of the steel wire rope body 6 and the sliding wheel structure 4 can be integrated into complex mold structures, avoiding interference with other components. In the trend of the thinning of consumer electronics products, this driving method can achieve efficient core-pulling in a limited space, support the thinning design of products, and enhance the product competitiveness.
[0036] Finally, the size of the driving wheel structure 502 will affect the accuracy of the core-pulling mechanism, mainly because it is related to the force transmission and the stability of the movement.
[0037] When the smaller driving wheel structure 502 rotates, the distance moved by each point on its circumference is relatively short. This means that under the action of the same driving force, the displacement change generated by the force transmitted through the smaller driving wheel structure 502 is relatively small, so that the moving distance and position of the core-pulling motion component 2 can be more precisely controlled, which helps to achieve higher accuracy.
[0038] On the contrary, when the larger driving wheel structure 502 rotates, each point on its circumference moves a longer distance. Under the action of the same driving force, the displacement change generated by the force transmitted through the larger driving wheel structure 502 is relatively large, making it difficult to precisely control the fine movement of the core-pulling fixture and possibly resulting in reduced accuracy.
[0039] In addition, during the rotation of the larger driving wheel structure 502, due to its relatively large moment of inertia, it is more susceptible to external factors such as vibration and impact force, thus affecting the stability and accuracy of the movement.
[0040] Since the driving wheel structure 502 within the adjustable driving structure 5 is replaceable, the accuracy can be flexibly adjusted according to different production requirements. In production that requires high precision, high-precision pulleys can be selected, while in production with relatively lower precision requirements, lower-cost pulleys can be chosen, thereby achieving the best balance between cost and precision.
[0041] The core-pulling motion component 2 includes a motion frame 201. A motion groove 202 is formed inside the motion frame 201. Sliding grooves 203 are provided on both the front and back sides of the motion groove 202. A clamping member mounting seat 204 is arranged inside the motion groove 202.
[0042] A number of rolling wheels 205 are connected to both the front and back sides of the clamping member mounting seat 204. The number of rolling wheels 205 are all installed in the sliding grooves 203 and can move along the sliding grooves 203. An installation groove 206 is formed on the left side wall of the clamping member mounting seat 204, and a number of four-corner installation grooves 207 are further provided outside the installation groove 206.
[0043] The detachable connection structure 3 includes a first fixing plate 301. A lifting seat 302 is fixedly connected to the right side wall of the first fixing plate 301. A second fixing plate 303 is fixedly connected to the right side wall of the lifting seat 302. A movable seat 304 is connected to the right side of the second fixing plate 303 by bolts. A wire rope connecting member 305 is fixedly connected to the right side wall of the movable seat 304.
[0044] The sliding wheel structure 4 includes two mounting side seats 401. A sliding wheel body 402 is arranged between the two mounting side seats 401. The sliding wheel body 402 and the two mounting side seats 401 are both connected by a rotating shaft.
[0045] The adjustable driving structure 5 includes a first mounting seat 501. A driving wheel structure 502 is arranged on the top of the first mounting seat 501. A driven turntable 503 is connected to the front of the driving wheel structure 502 by a rotating shaft. A driving turntable 504 is connected to the front of the driven turntable 503 by bolts.
[0046] The adjustable drive structure 5 further includes a drive motor 505. The bottom of the drive motor 505 is fixedly connected with a second mounting seat 506. The drive motor 505 can be detachably connected to the mechanism base 1 through the second mounting seat 506, so as to adjust the position of the drive motor 505.
[0047] In the embodiment of the present application, the implementation principle of a combined angled lifter core-pulling mechanism is as follows: When the combined angled lifter core-pulling mechanism starts to work, the drive motor 505 is started. The rotation of the drive motor 505 drives the active turntable 504 to rotate. The driven turntable 503 connected by bolts rotates accordingly, and then drives the drive wheel structure 502 to rotate.
[0048] The rotation of the drive wheel structure 502 transmits power through the steel wire rope body 6. The steel wire rope body 6 pulls the steel wire rope connector 305 in the detachable connection structure 3 connected thereto.
[0049] Under the action of the pulling force, the movable seat 304, the second fixed plate 303 and the elevation seat 302 drive the first fixed plate 301 to generate displacement.
[0050] The first fixed plate 301 is connected to the core-pulling motion assembly 2, and then pushes the motion frame 201 in the core-pulling motion assembly 2.
[0051] The clamping part mounting seat 204 inside the motion frame 201 moves in the motion groove 202. The rolling wheels 205 on the front and back sides of the clamping part mounting seat 204 roll along the sliding groove 203, making the movement of the clamping part mounting seat 204 smoother and more stable.
[0052] Meanwhile, the sliding wheel body 402 in the sliding wheel structure 4 at the top and inside of the mechanism base 1 rotates along with the movement of the steel wire rope body 6, playing a role of auxiliary guiding and stabilizing the movement.
[0053] During the whole working process, since the drive wheel structure 502 is replaceable, a suitable size of the drive wheel structure 502 can be selected according to different production precision requirements. If high-precision production is required, a smaller drive wheel structure 502 is selected to achieve a more precise core-pulling action; for production with relatively low precision requirements, a larger drive wheel structure 502 can be selected to improve work efficiency on the premise of meeting the precision requirements.
[0054] In addition, when it is necessary to adjust the position of the drive motor 505 (in order to cope with the position change brought about by the replacement of different drive wheel structures 502) or for maintenance, it can be removed from the mechanism base 1 through the detachable second mounting seat 506.
[0055] The above embodiments are only the preferred embodiments of the present utility model, and the scope of protection of the present utility model cannot be limited thereby. Any non-substantive changes and substitutions made by those skilled in the art based on the present utility model fall within the scope of protection required by the present utility model.
