Description

Technical Field

[0001] The utility model relates to the technical field of insulator moulds, in particular to a core-pulling and core-sandwiching mechanism and an insulator mould having the same. Background Art

[0002] Insulator products are generally formed by injection molding using insulator molds. In some insulator molds, in order to ensure the quality of the insulator products formed by injection molding, it is often necessary to set a core rod clamp to clamp the core rod to avoid displacement of the core rod and improve the qualified rate of the insulator products.

[0003] Insulator products generally have multiple leaves, and the core rod clamp for clamping the core rod generally needs to be inserted between two leaves, so that the core rod can be entered from the outside of the insulator product. The core rod clamp is set perpendicular to the core rod and clamps the core rod. However, since the existing core rod clamp needs to clamp or loosen the core rod during use, it is only suitable for insulator products with a large interval between the two leaves or a large angle of the leaf angle. If it is necessary to prepare an insulator product with a small interval between the two leaves or a small angle of the leaf angle, the setting of the core rod clamp will interfere with the injection groove or the mold cavity. Therefore, the insulator mold with the core rod clamp cannot prepare an insulator product with a small interval between the two leaves or a small angle of the leaf angle, resulting in low versatility of the insulator mold. Utility Model Content

The clamping rod can clamp or release the core rod to avoid the core rod from shifting or tilting during the injection process, thereby ensuring the quality of the prepared insulator product; since the angle between the second direction and the first direction is an acute angle, the clamping rod can avoid the mold cavity position on the insulator mold during movement, and can be applied even to insulator molds for preparing insulator products with a small interval between two umbrella leaves or a small umbrella leaf angle, and has higher versatility.

[0035] Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. The various technical features in the utility model can be combined interchangeably without conflicting with each other.

[0036] Reference Figures 1 to 8 The embodiment of the utility model proposes a core-pulling and core-sandwiching mechanism, which is arranged on an insulator mold and can perform core-pulling and core-sandwiching actions on the mold of an insulator product with a small distance between two umbrella leaves or a small umbrella leaf angle.

[0037] In this embodiment, the core pulling sandwich mechanism includes a mounting seat, a sandwich assembly, a driving block 200 and a linear driving component. The linear driving component serves as a driving source and has an output end, and the output end of the linear driving component is connected to the driving block 200. Under the driving action of the linear driving component, the driving block 200 can move along the first direction.

[0038] For the convenience of description, the front-to-back direction is defined as the first direction.

[0039] In this embodiment, the mounting seat is provided with a movable hole 320 and a mounting groove 310. The movable hole 320 is extended along the front-to-back direction and penetrates the front wall and the rear wall of the mounting seat. The mounting groove 310 penetrates the left and right walls of the mounting seat and extends along the second direction, and an angle is formed between the second direction and the first direction, and the angle is an acute angle.

[0040] It can be understood that the installation groove 310 and the movable hole 320 are connected to each other. Specifically in this embodiment, the direction inclined from the left rear to the right front is set as the second direction.

[0041] The driving block 200 is inserted into the movable hole 320. When the linear driving component is driven, the driving block 200 slides along the first direction relative to the hole wall of the interactive hole. In this embodiment, a guide groove 210 is provided on the upper surface of the driving block 200. The guide groove 210 is extended along the third direction. There is an angle between the third direction and the first direction, and the angle is an acute angle. In this embodiment, there is an angle between the third direction and the second direction. In this embodiment, the direction inclined from the left front to the right rear is set as the third direction, and the angle between the second direction and the third direction is 90°.

[0042] It can be understood that the first direction, the second direction and the third direction are all perpendicular to the up-down direction.

[0043] The sandwich assembly in this embodiment includes a clamping rod 100 and a slider 111. The clamping rod 100 is extended along the second direction. One end of the clamping rod 100 extends out of the end surface of the mounting groove 310 in the second direction to clamp the mold core rod. The other end of the clamping rod 100 is located in the mounting groove 310 and can slide relative to the groove wall of the mounting groove 310. When the clamping rod 100 moves along the mounting groove 310 in the second direction, the clamping rod 100 can clamp or release the mold core rod.

[0044] The clamping rod 100 is arranged above the driving block 200. The clamping rod 100 is installed at one end of the mounting groove 310 and is connected to the slider 111. The slider 111 protrudes downward and can be inserted downward into the guide groove 210 of the driving block 200. The slider 111 can slide relative to the groove wall of the guide groove 210.

[0045] It can be understood that when the driving block 200 moves along the first direction, the guide groove 210 moves relative to the slider 111, and because the guide groove 210 is arranged at an angle, under the limiting effect of the groove wall of the guide groove 210 and the limiting effect of the groove wall of the mounting groove 310 on the clamping rod 100, the slider 111 and the clamping rod 100 can move along the second direction, thereby enabling the clamping rod 100 to clamp the core rod through the driving action of the linear driving component.

[0046] It can be understood that even for insulator products with a small interval between two blades or a small blade angle, the setting of the sandwich assembly can avoid the blade position of the insulator product. When the core-pulling sandwich mechanism is applied to the insulator mold, the clamping rod 100 will not affect the injection molding of the insulator product, and can clamp and fix the core rod, thereby obtaining a high-quality insulator product.

[0047] In this embodiment, the clamping rod 100 includes a first rod body 110 and a second rod body 120, and the first rod body 110 and the second rod body 120 are both extended along the second direction. The first rod body 110 is disposed in the mounting groove 310, the first rod body 110 is slidably connected to the groove wall of the mounting groove 310, and the slider 111 is connected and fixed to the lower surface of the first rod body 110. One end of the second rod body 120 is hinged to the first rod body 110, and the other end extends toward the placement direction of the core rod and protrudes out of the mounting groove 310.

[0048] It can be understood that the hinge axis of the second rod body 120 is perpendicular to the second direction and the up-down direction.

[0049] Furthermore, the first rod body 110 is provided with a rotating groove 112, which passes through the upper surface and the lower surface of the first rod body 110, and the rotating groove 112 is opened toward the second direction. A rotating hole is provided on the inner wall surface of the rotating groove 112, and a rotating shaft 121 is provided at one end of the second rod body 120. The rotating shaft 121 passes through the rotating holes on both sides of the rotating groove 112 and is rotatably connected to the hole wall of the rotating hole. The other end of the second rod body 120 extends along the second direction and extends out of the rotating groove 112, and abuts against the core rod.

[0050] It can be understood that the extending direction of the rotating shaft 121 is the extending direction of the hinge axis of the second rod body 120 , and the rotating shaft 121 is perpendicular to the second direction and the up-down direction.

[0051] It is understandable that when the insulator product needs to be demoulded, the operator can rotate the second rod body 120 upward to separate the second rod body 120 from the insulator product, so as to remove the burrs of the insulator product.

[0052] When installing the first rod body 110 and the second rod body 120, the second rod body 120 is directly placed in the rotation groove 112 of the first rod body 110, the rotation shaft 121 is passed through the rotation hole from the outside of the first rod body 110, and the rotation shaft 121 is passed through the second rod body 120, so that the assembly is convenient and quick. After completing the above assembly process, the first rod body 110 is inserted into the installation groove 310, and the groove wall of the installation groove 310 can limit the rotation shaft 121 to prevent the rotation shaft 121 from falling out of the rotation hole.

[0053] In this embodiment, the mounting seat includes a seat body 300 and a cover body 400, the mounting groove 310 is arranged on the upper surface of the seat body 300, and the cover body 400 covers the top of the mounting groove 310 and is detachably connected to the upper surface of the seat body 300 by bolts and other connecting parts.

[0054] In this embodiment, bolts for connecting the base body 300 and the cover body 400 are passed through the upper surface and the lower surface of the base body 300, and extend downward to the frame for installing the base body 300, thereby ensuring the connection strength between the base body 300 and the cover body 400, while preventing the base body 300 from moving on the frame, and also reducing the use of connecting parts.

[0055] It is understandable that the cover 400 can protect the installation groove 310 to prevent debris from entering the installation groove 310 and even blocking the guide groove 210. When the cover 400 is separated from the base 300, the operator can easily install the first rod 110, the second rod 120 and other components, and can maintain the first rod 110 and other components located in the installation groove 310 to ensure the stable performance of the core-pulling sandwich mechanism.

[0056] In addition, in this embodiment, the cover body 400 is provided with a movable opening 410, which penetrates the upper surface and the lower surface of the cover body 400, and is communicated with the mounting groove 310, and is opened toward the core rod. It can be understood that the movable opening 410 is used to avoid the second rod body 120, and when the second rod body 120 rotates relative to the first rod body 110, it can enter and exit the movable opening 410, and the second rod body 120 can rotate upward to facilitate demoulding of the insulator product.

[0057] It can be understood that the cover body 400 partially covers the top of the second rod body 120. When the linear drive component does not drive the clamping rod 100 to move along the second direction to the position abutting the core rod, the setting of the cover body 400 can limit the rotation movement of the second rod body 120 relative to the first rod body 110, so that the initial state of the second rod body 120 remains horizontal, thereby enabling the second rod body 120 to clamp the core rod more stably and ensure the placement stability of the core rod.

[0058] In this embodiment, an end surface of the second rod 120 extending from the rotation slot 112 is an arcuate surface 122 , and the arcuate surface 122 is recessed toward one end of the first rod 110 .

[0059] It is understandable that such a configuration can increase the contact area between the second rod body 120 and the core rod, thereby improving the clamping strength of the core rod and preventing the core rod from being offset.

[0060] It is understandable that, in order to further prevent the core rod from being deflected, a general insulator mold needs to clamp and fix the core rod at least at two positions, that is, two sets of core pulling and clamping mechanisms need to be provided.

[0061] In the present embodiment, two mounting seats, two sandwich assemblies and two drive blocks 200 are respectively provided for the core pulling sandwich mechanism. A linear drive component is connected to one of the drive blocks 200, and the two drive blocks 200 are connected in series through a transmission rod. Thus, the two drive blocks 200 can be precisely moved by one linear drive component, and the movements of the two drive blocks 200 are kept synchronized, thereby ensuring that the clamping rods 100 of the two sandwich assemblies apply the same pressure to the core rod, thereby preventing the core rod from tilting to one side and ensuring the quality of the insulator product.

[0062] It is understandable that the mounting seat, the sandwich assembly and the driving block 200 can also be set to other numbers, and two adjacent driving blocks 200 are connected in series through a transmission rod. Multiple sandwich assemblies apply force to multiple positions of the core rod respectively to keep the core rod stable.

[0063] It is understandable that the linear drive component can be manual or automatic, such as an electric cylinder, a pneumatic cylinder, etc., which is not specifically limited here.

[0064] In some embodiments, the driving block 200 is provided with a slot 220 , an output rod 500 is provided between the output end of the linear driving component and the driving block 200 , and a block 510 is provided at the end of the output rod 500 , and the block 510 is engaged in the slot 220 .

[0065] It can be understood that the driving block 200 and the output rod 500 are connected by the clamping block 510 and the clamping slot 220, which is convenient and quick to install. In this embodiment, the clamping slot 220 is a T-shaped slot opened upward, and the shape of the clamping block 510 corresponds to the clamping slot 220. The clamping block 510 can be directly inserted from the upper opening of the clamping slot 220 to achieve clamping, which makes installation simpler and quicker.

[0066] In this embodiment, a nut is provided at the output end of the linear drive component, and the output rod 500 is threadedly connected to the output end of the linear drive component through the nut, and the end of the clamping block 510 is a truncated cone structure, and the clamping block 510 can rotate relative to the groove wall of the clamping groove 220, so that the relative movement between the linear drive component and the driving block 200 is more flexible. It can be understood that the operator can adjust the relative position between the body of the linear drive component and the driving block 200 by rotating the output rod 500, thereby adjusting the active position of the clamping rod 100, or realizing the locking between the linear drive component and the output rod 500.

[0067] In this embodiment, a plurality of sockets 520 are provided on the output rod 500. The sockets 520 are provided through the side wall surface of the output rod 500. The sockets 520 can be used for inserting a crowbar. When in use, the operator can insert the crowbar into the sockets 520 to apply torque to the output rod 500, thereby realizing the rotation of the output rod 500.

[0068] In the embodiment in which a plurality of drive blocks 200 are provided, two drive blocks 200 are connected together by a transmission rod, and the specific structure of the transmission rod is the same as that of the output rod 500. One end of the transmission rod having a clamping hole is connected to the drive block 200 far away from the linear drive component, and is clamped in the clamping groove 220 of the drive block 200. The other end of the transmission rod is connected to the drive block 200 close to the linear drive component, and the drive block 200 is provided with a nut, and the transmission rod is rotatably connected to the drive block 200 through the nut. When in use, the operator can use a crowbar to insert into the jack 520 on the transmission rod, and provide torque to the transmission rod, so that the transmission rod rotates relative to the drive blocks 200 at both ends, so that the relative distance between the two drive blocks 200 can be adjusted, or the separation between the two drive blocks 200 can be achieved.

[0069] On the other hand, an embodiment of the utility model further provides an insulator mold, which includes the core-pulling and core-sandwiching mechanism provided in any one of the above embodiments.

[0070] It can be understood that, due to the provision of the core-pulling and core-sandwiching mechanism, the insulator mold of this embodiment can produce insulator products with a small distance between two umbrella leaves or a small umbrella leaf angle.

[0071] It can be understood that the insulator mold is provided with an upper mold base and a lower mold base, and a parting surface 600 is formed between the upper mold base and the lower mold base. After the upper mold base and the lower mold base are molded together, a mold cavity 610 and a movable groove are formed. The movable groove is extended along the second direction and connected to the mold cavity 610, and the movable groove matches the second rod body 120 of the sandwich assembly. When in use, the mold cavity 610 is filled with slurry and shaped to obtain the desired insulator product.

[0072] It can be understood that the second rod body 120 moves in the movable groove, and the end surface of the second rod body 120 having the arc surface 122 can clamp the core rod to ensure the stability of the core rod.

[0073] In this embodiment, the width of the second rod body 120 gradually increases from the upper end to the middle part, and gradually decreases from the middle part to the lower end, that is, the upper end of the second rod body 120 is provided with a taper toward the upper part, and the lower end of the second rod body 120 is provided with a taper toward the lower part. The shape of the groove wall of the movable groove cooperates with the outer surface shape of the second rod body 120. The groove wall of the movable groove can position the second rod body 120, and the setting of the taper can allow the groove wall of the movable groove to guide the second rod body 120 during the mold closing process, thereby avoiding damage to the second rod body 120 when the upper mold base and the lower mold base are closed, thereby extending the service life of the core-pulling sandwich mechanism.

[0074] The preferred implementation modes of the present invention are specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
