Abstract
Description
Technical Field
[0001] This utility model relates to the field of injection mold processing fixtures, specifically a fixture for processing injection mold inserts. Background Technology
[0002] Injection molding is divided into rubber injection molding and plastic injection molding, both of which involve injecting molten rubber or plastic into a mold under pressure to obtain a molded product. Injection molds are crucial tools for ensuring the precision and quality of molded products. Fixtures for injection mold insert processing are auxiliary devices used to clamp and fix the injection mold for insert processing.
[0003] A search revealed a patent document with publication number CN222628425U, which discloses a fixture for processing injection mold inserts. The fixture includes: a processing table; a first hydraulic cylinder fixedly connected to the middle of both upper ends of the processing table; a first clamping plate fixedly connected to the extension end of each first hydraulic cylinder; a second clamping plate provided at one end of each first clamping plate; a first sliding groove formed inside both the first and second clamping plates; a first slider slidably engaged inside the first sliding groove; the first slider and the second clamping plate fixedly connected; and second hydraulic cylinders fixedly connected to the middle of both upper and lower sides of the processing table. The extension ends of the second hydraulic cylinders slidably engage with the second clamping plates. This invention includes a fan, a collection hood, and a circulating water tank. The fan introduces external gas, which is discharged through the collection hood, thus facilitating gas circulation in the injection mold, accelerating cooling, and simplifying demolding operations.
[0004] In the prior art, clamping and fixing are achieved by combining a first clamping plate and a second clamping plate. The first clamping plate and the second clamping plate can slide together to form a synchronous movement effect. However, in the prior art, due to the limitation of the length of the first clamping plate and the second clamping plate themselves, it is not possible to clamp and fix molds with a width shorter than the length of the second clamping plate. Therefore, a new type of fixture for processing injection mold inserts is proposed to optimize the prior art. Utility Model Content
[0005] The purpose of this utility model is to provide a fixture for processing injection mold inserts, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A fixture for machining injection mold inserts includes a machining table. A first clamping seat is fixedly connected to the machining table. A second clamping seat is provided on the outer diagonal side of the first clamping seat. Both the second clamping seat and the first clamping seat have a mounting cavity at their lower parts. A mounting base is rotatably connected to the mounting cavity of the first clamping seat. A threaded seat is rotatably mounted in the mounting cavity of the second clamping seat. The mounting base extends out of the first clamping seat and a motor is fixedly mounted on its end face. A threaded rod is fixedly connected to the output end of the motor. The rotation of the threaded rod passes through the mounting base and the thread passes through the threaded seat. A support handle is fixedly connected to the second clamping seat. The motor is externally connected to a power supply and a switch. The switch can be mounted on the support handle.
[0008] As a further embodiment of this utility model: a third clamping seat is provided on each of the adjacent sides of the first clamping seat, and ball wheels are fixedly installed on the bottom surfaces of the third clamping seat and the second clamping seat, and the ball wheels travel on the processing table.
[0009] As a further embodiment of this utility model: the third clamping seat and the first clamping seat are symmetrically and slidably connected to the first guide rod on the corresponding side. The third clamping seat is provided with a circular hole for the first guide rod to pass through and slide. One end of the first guide rod is fixedly connected to the first clamping seat.
[0010] As a further embodiment of this utility model: the third clamping seat is symmetrically and fixedly connected to the second clamping seat on one side. The second guide rods connected to the two third clamping seats are staggered vertically. One end of the second guide rod slides through the second clamping seat. The second clamping seat is provided with two sets of circular holes through which the second guide rods pass and slide.
[0011] As a further improvement of this utility model, the top surfaces of the third clamping seat, the second clamping seat, and the first clamping seat are all fixedly connected with clamping baffles.
[0012] As a further embodiment of this utility model: the inner side of each clamping stop is provided with a clamping block adapted to it, the clamping block slides against the top surface of the third clamping seat, the second clamping seat and the first clamping seat, and the clamping stop is connected to the clamping block diagonally through a threaded knob, the threaded knob is threadedly connected to the clamping block.
[0013] As a further embodiment of this utility model: the clamping block is provided with an extension guide bar corresponding to the threaded knob, the clamping stop is provided with a sliding cavity corresponding to the extension guide bar, the extension guide bar is slidably connected in the sliding cavity, and the extension guide bar is provided with a threaded hole for the threaded knob to be inserted and threadedly connected.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. This utility model uses a motor to drive the threaded rod to rotate, which, in conjunction with the threaded seat, can drive the second clamping seat and the first clamping seat to move. Since both the mounting seat and the threaded seat are rotatably installed in the mounting cavity, the lateral and longitudinal positions of the second clamping seat can be manually adjusted by supporting the handle, making it convenient to adapt to molds of different sizes for clamping and fixing of inserts. The whole assembly only clamps the diagonal of the mold, and the clamping width is narrow, which is smaller than the minimum width that can be adapted by the above-mentioned prior art.
[0016] 2. This utility model provides support and clamping at the other two corners of the mold through a third clamping seat, which provides auxiliary support and improves the stability of clamping.
[0017] 3. The third and second clamping seats of this utility model can move on the processing table through ball wheels, thereby facilitating the rolling movement effect during adjustment, avoiding direct friction between the third and second clamping seats and the processing table during movement, and improving the smoothness of movement of the third and second clamping seats.
[0018] 4. The third clamping seat of this utility model is aligned with the first clamping seat by the first guide rod and forms a moving guide. The second guide rod aligns the second clamping seat with the third clamping seat and forms a moving guide. Thus, with the cooperation of the first guide rod and the second guide rod, the second clamping seat and the third clamping seat can form a linkage effect and maintain moving alignment.
[0019] 5. When the third clamping seat, the second clamping seat and the first clamping seat of this utility model are close to each other, the clamping edge can be used to clamp the mold workpiece that needs to be clamped. During clamping, the rotation of the threaded knob, in conjunction with the guide of the extension guide and the sliding cavity, drives the clamping block to further press against the mold workpiece, thereby improving the clamping force.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figures 1-3 In this embodiment of the present invention, a fixture for processing injection mold inserts includes a processing table 1, a first clamping seat 2 fixedly connected to the processing table 1, a second clamping seat 3 provided on the diagonal outer side of the first clamping seat 2, and a mounting cavity 4 provided at the lower part of both the second clamping seat 3 and the first clamping seat 2. A mounting seat 5 is rotatably connected in the mounting cavity 4 of the first clamping seat 2, and a threaded seat 6 is rotatably installed in the mounting cavity 4 of the second clamping seat 3. The mounting seat 5 extends out of the first clamping seat 2 and a motor 7 is fixedly installed on its end face. A threaded rod 8 is fixedly connected to the output end of the motor 7. The rotation of the threaded rod 8 passes through the mounting seat 5 and the thread passes through the threaded seat 6. A support handle 18 is fixedly connected to the second clamping seat 3. The motor 7 is externally connected to a power supply and a switch, and the switch can be installed on the support handle 18.
[0026] The motor 7 drives the threaded rod 8 to rotate, which, in conjunction with the threaded seat 6, drives the second clamping seat 3 and the first clamping seat 2 to move. Since the mounting seat 5 and the threaded seat 6 are both rotatably installed in the mounting cavity 4, the lateral and longitudinal positions of the second clamping seat 3 can be manually adjusted by the support handle 18, which is convenient for clamping and fixing molds of different sizes for insert processing. The whole clamps only the diagonal of the mold, and the clamping width is narrow, which is smaller than the minimum width that can be adapted by the above-mentioned prior art.
[0027] A third clamping seat 9 is provided on each of the adjacent sides of the first clamping seat 2. A ball wheel 10 is fixedly installed on the bottom surface of the third clamping seat 9 and the second clamping seat 3. The ball wheel 10 travels on the processing table 1.
[0028] The third clamping seat 9 provides support and clamping at the other two corners of the mold, providing auxiliary support and improving clamping stability.
[0029] The third clamping seat 9 and the second clamping seat 3 can move on the processing table 1 via the ball wheel 10, thereby facilitating a rolling movement effect during adjustment, avoiding direct friction between the third clamping seat 9 and the second clamping seat 3 and the processing table 1 during movement, and improving the smoothness of movement of the third clamping seat 9 and the second clamping seat 3.
[0030] The third clamping seat 9 and the first clamping seat 2 are symmetrically and slidably connected to the first guide rod 11 on the corresponding side. The third clamping seat 9 has a round hole for the first guide rod 11 to pass through and slide. One end of the first guide rod 11 is fixedly connected to the first clamping seat 2.
[0031] The third clamping seat 9 is symmetrically fixedly connected to the second clamping seat 3 on one side. The second guide rods 12 connected to the two third clamping seats 9 are staggered vertically. One end of the second guide rod 12 slides through the second clamping seat 3. The second clamping seat 3 is provided with two sets of circular holes through which the second guide rods 12 slide.
[0032] The third clamping seat 9 is aligned with the first clamping seat 2 via the first guide rod 11, forming a moving guide. The second clamping seat 3 is aligned with the third clamping seat 9 via the second guide rod 12, forming a moving guide. Thus, with the cooperation of the first guide rod 11 and the second guide rod 12, the second clamping seat 3 and the third clamping seat 9 can form a linkage effect and maintain moving alignment.
[0033] The top surfaces of the third clamping seat 9, the second clamping seat 3, and the first clamping seat 2 are all fixedly connected with clamping baffles 13.
[0034] The inner side of the clamping edge 13 is provided with a clamping block 14 that is adapted to it. The clamping block 14 slides in contact with the top surface of the third clamping seat 9, the second clamping seat 3 and the first clamping seat 2. The clamping edge 13 is connected to the clamping block 14 diagonally through a threaded knob 15, which is threaded to the clamping block 14.
[0035] The clamping block 14 is provided with an extension guide 16 corresponding to the threaded knob 15. The clamping stop 13 is provided with a sliding cavity 17 corresponding to the extension guide 16. The extension guide 16 is slidably connected in the sliding cavity 17. The extension guide 16 is provided with a threaded hole for the threaded knob 15 to be inserted and threadedly connected.
[0036] When the third clamping seat 9, the second clamping seat 3 and the first clamping seat 2 are close to each other, the clamping edge 13 can clamp the mold workpiece that needs to be clamped. During clamping, the rotation of the threaded knob 15, together with the guide of the extension guide 16 and the sliding cavity 17, can drive the clamping block 14 to further press against the mold workpiece, thereby increasing the clamping force.
[0037] The working principle of this utility model is as follows:
[0038] In use, the mold workpiece to be processed is suspended on the processing table 1 and corresponds to the first clamping seat 2. At this time, the motor 7 is started, driving the threaded rod 8 to rotate. With the cooperation of the threaded seat 6, the second clamping seat 3 is driven to move closer to the first clamping seat 2. At this time, the position of the second clamping seat 3 can be adjusted by the support handle 18 to correspond diagonally with the mold workpiece. When the second clamping seat 3 moves, the third clamping seat 9 can be moved along the first guide rod 11 synchronously by the second guide rod 12, so that the third clamping seat 9 corresponds to the other two diagonals of the mold workpiece. Thus, the mold can be clamped and supported on the first clamping seat 2, the second clamping seat 3 and the third clamping seat 9 and located in the clamping stop 13. At this time, the threaded knob 15 is further rotated, and the guide driving clamping block 14 of the extension guide 16 and the sliding cavity 17 further presses against the mold workpiece, completing the clamping and fixing of the mold workpiece, which is convenient for the processing equipment to process.
[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
