[0050] In this technical solution, the fixed mold and the movable mold are respectively installed on a conventional machine table by bolts, etc., to provide power for the opening and closing of the fixed mold and the movable mold. A guide rod slidably inserted into the movable mold is provided in the fixed mold, and a guide sleeve corresponding to the guide rod is provided in the movable mold to improve the matching accuracy of the fixed mold and the movable mold. The fixed mold base plate, the fixed mold upper template and the fixed mold lower template are fixed to each other by conventional bolts, etc. In order to prevent the fixed mold and the movable mold from being installed incorrectly, an anti-fool boss is fixedly provided on the fixed mold lower template, and an anti-fool boss groove is provided on the movable mold template to match the anti-fool boss. When the mold is closed, the anti-fool boss can be stuck in the anti-fool groove. The fixed mold upper template is concave with a fixed mold The groove of the ejection mechanism, the fixed mold ejection mechanism is slidably arranged in the groove, the movable mold base plate and the movable mold plate are spaced apart by a support plate, the movable mold ejector plate is slidably arranged between the movable mold base plate and the movable mold plate through conventional guide columns and linear bearings / bushings, and the two ends are encapsulated by conventional cover plates to prevent debris from entering and causing the movable mold ejector plate to fail to operate normally; the opener and shutter use conventional elastic or mechanical openers, and drive the ejection mechanism with the action of the movable mold, that is, the fixed mold and the movable mold are respectively provided with a fixed mold ejection mechanism and a movable mold ejector plate, and the cable tie is ejected from both sides to reduce the stress deformation of the cable tie during the mold opening process.

[0051] For example, see Figures 1 to 23 As shown, the fixed mold core 4 includes a fixed mold insert 41 and a fixed mold core plate 42 respectively arranged at both ends of the fixed mold insert 41, the movable mold core 9 includes a movable mold insert 91 and a movable mold core plate 92 respectively arranged at both ends of the movable mold insert 91, and the molding mold cavity 10 includes a body cavity 101 arranged between the corresponding fixed mold core plate 42 and the movable mold core plate 92 and a head cavity between the fixed mold insert 41 and the movable mold insert 91.

[0052] In this technical solution, an installation groove for installing the fixed mold core is provided in the end surface of the fixed mold lower mold plate close to the movable mold core. The fixed mold insert and the fixed mold insert are respectively fixed in the installation groove by bolts, etc., and the movable mold insert and the movable mold insert are fixed in the movable mold template by the same structure. In order to improve production efficiency, two head cavities are respectively provided at both ends of the fixed mold insert and the fixed mold insert, and two belt body cavities are provided between the corresponding fixed mold core plate and the movable mold core plate, that is, the production of four cable ties can be completed by opening and closing the mold once.

[0053] For example, see Figures 1 to 23 As shown, a fixed mold top block 43 is slidably provided in the fixed mold insert 41, and a movable mold top block 93 is slidably provided in the movable mold insert 91. The head cavity includes a snap-fit ​​cavity 102 provided between the fixed mold insert 41 and the movable mold insert 91, a staple cavity 103 provided between the fixed mold top block 43 and the movable mold top block 93, and a support plate cavity 104 provided between the snap-fit ​​cavity 102 and the staple cavity 103. A first molding block 44 and a second molding block 94 extending into the snap-fit ​​cavity 102 are respectively embedded in the fixed mold insert 41 and the movable mold insert 91.

[0054] In this technical solution, the cable tie is an existing disc-shaped fir-head threaded head fixed cable tie / pin-type nylon cable tie, which includes a belt body, a buckle, a support plate and a staple arranged in sequence, wherein the belt body is evenly distributed with convex teeth, the buckle is provided with a through hole for the belt body to pass through, and the through hole is provided with a ratchet matching the convex teeth, the support plate is an arc surface structure, and the staple is provided with several blades with arc surface structures. The belt body cavity, buckle cavity, support plate cavity and staple cavity of the molding mold cavity are respectively arranged corresponding to the belt body, buckle, support plate and staple of the cable tie. The first forming block and the second forming block extend into the buckle cavity to form a through hole and a ratchet in the buckle, wherein the first forming block includes a sliding block and a fixed block. In order to facilitate identification of numbers / texts and other labels engraved on the sliding block, the fixed block and the second forming block, a through groove is provided on the fixed mold insert, the sliding block and the fixed block are arranged in the through groove, and the sliding block is slidably arranged relative to the through groove; the through groove is perpendicular to the fixed mold, that is, parallel to the moving direction of the movable mold, and a clearance groove and a fixed groove are provided on the fixed mold insert. The clearance groove and the fixed groove are both located at one end of the through groove away from the movable mold. A blocking part is provided on the sliding block, and the blocking part is arranged corresponding to the clearance groove. A fixing part is provided on the fixed block, and the fixing part corresponds to the fixed groove. The sliding block passes through the clearance groove The fixed block is mounted on the fixed mold insert, and is fixed to the fixed mold insert via a fixing groove. The length of the clearance groove along the sliding direction of the movable mold is greater than the length of the blocking portion along the sliding direction of the movable mold, so that the sliding block can drive the blocking portion to slide within the clearance groove. The end of the sliding block away from the blocking portion corresponds to the tooth side of the buckle ratchet, and the fixed block corresponds to the back of the buckle ratchet of the cable tie tongue. During use, when the cable tie moves in a direction away from the fixed mold insert, the buckle ratchet can drive the sliding block to move, and the fixed block can automatically disengage from the cable tie. When the fixed block is completely disengaged from the back of the buckle ratchet, the blocking portion on the sliding block is abutted by the wall of the clearance groove and stops moving, and then the sliding block can squeeze the buckle ratchet to deform, causing the buckle ratchet to fall off the sliding block. The buckle, support plate and staple are all biased to one side in the thickness direction of the belt body. The fixed mold insert protrudes toward the side close to the movable mold insert, and the movable mold insert is correspondingly recessed, so that the support plate cavity and staple cavity are evenly distributed on the fixed mold and the movable mold, and it can also facilitate the demolding of the buckle.

[0055] For example, see Figures 1 to 23As shown, a first sliding cavity 411 corresponding to the fixed mold top block 43 is provided in the fixed mold insert 41, and a first half groove is recessed on the side wall of the first sliding cavity 411 close to the buckle cavity 102. A second sliding cavity 911 corresponding to the movable mold top block 93 is provided in the movable mold insert 91, and a second half groove is recessed on the side wall of the second sliding cavity 911 close to the buckle cavity 102. A first boss is protruded from the side wall of the fixed mold top block 43 close to the buckle cavity 102, and a second boss is protruded from the side wall of the movable mold top block 93 close to the buckle cavity 102. A support disc cavity 104 is formed between the first half groove and the second half groove and the first boss and the second boss.

[0056] In this technical solution, half of the support disc cavity is formed between the first boss and the first half groove, and the other half of the support disc cavity is formed between the second boss and the second half groove. When the support disc is demolded, the fixed mold top block and the movable mold top block are respectively relative to the fixed mold insert and the movable mold insert to complete the demolding of one side of the support disc, and then the relative movement of the fixed mold top block and the movable mold top block is used to complete the demolding of the other side, thereby reducing the extrusion of the support disc and improving the qualified rate of the product.

[0057] For example, see Figures 1 to 23 As shown, the contact surface between the fixed mold top block 43 and the first sliding cavity 411 away from the buckle cavity 102 and the contact surface between the movable mold top block 93 and the second sliding cavity 911 away from the buckle cavity 102 are inclined structures.

[0058] In this technical solution, after the fixed mold top block and the movable mold top block slide out of the corresponding fixed mold insert and the movable mold insert, there is no axial support along the support disk, which reduces the extrusion of the support disk and improves the product qualification rate.

[0059] For example, see Figures 1 to 23 As shown, a third forming block 30 is respectively embedded in the side walls of the fixed mold top block 43 and the movable mold top block 93 near the snap cavity 102. The third forming block 30 extends to the staple cavity 103 and is recessed with a rib cavity 301 corresponding to the staple reinforcement rib. The side wall of the third forming block 30 near the snap cavity 102 is flush with the side wall of the corresponding fixed mold top block 43 or the movable mold top block 93.

[0060] In this technical solution, the third forming block is fixed to the corresponding fixed mold top block or movable mold top block by bolts, etc., and is flush with the side walls of the corresponding fixed mold top block and the first boss or the movable mold top block and the second boss. The third forming block reduces the processing difficulty of the fixed mold top block and the movable mold top block.

[0061] For example, see Figures 1 to 23 As shown, the fixed mold lower template 3 and the movable mold template 8 are respectively provided with plug bolts 40 connected to the corresponding fixed mold top block 43 and the movable mold top block 93, and are sleeved with a first spring 401 that is supported on the fixed mold top block 43 or the movable mold top block 93.

[0062] In this technical solution, the plugging bolts can prevent the fixed mold top block and the movable mold top block from being separated from the corresponding fixed mold lower mold plate and movable mold plate. After the fixed mold top block and the movable mold top block lose the force of the corresponding fixed mold top rod and the movable mold top rod, they still remain in the state of extending out from the corresponding fixed mold insert and the movable mold insert under the action of the first spring.

[0063] For example, see Figures 1 to 23 As shown, the fixed mold ejection mechanism 5 includes a fixed mold ejector plate slidably set in the fixed mold upper mold plate 2, the fixed mold ejector plate is elastically abutted against the fixed mold upper mold plate 2 through a second spring 50, and is provided with a fixed mold ejector rod 51 abutting against the fixed mold ejector block 43 and a fixed mold ejector pin 52 sliding through the molding cavity 10, and the movable mold ejector plate 7 is slidably set between the movable mold base plate 6 and the movable mold mold plate 8, and is provided with a movable mold ejector rod 71 abutting against the movable mold ejector block 93 and a movable mold ejector pin 72 sliding through the molding cavity 10.

[0064] In this technical solution, both the fixed mold ejector plate and the movable mold ejector plate are double-layer structures, and the mounting ends of the fixed mold ejector and the movable mold ejector are T-shaped shaft structures and embedded in the corresponding fixed mold ejector plate and the movable mold ejector plate. The fixed mold ejector includes a first ejector (engraved with "A1") corresponding to the connection between the belt body and the buckle, a second ejector (engraved with "A2") corresponding to the clip, and a third ejector (engraved with "A3") for guiding the fixed mold ejector block. The bottom surface of the first ejector (close to the end surface of the cable tie) is processed with a The inclined surface corresponding to the buckle, the first ejector acts on the belt body and the buckle at the same time. In order to facilitate its installation and positioning, the top T-axis structure is processed with a positioning plane. The bottom end of the second ejector (the end close to the cable tie) is a sheet structure and is parallel to the reinforcement rib of the staple. It slides through the corresponding third forming block. The movable mold ejector includes a fourth ejector (engraved with "B1") corresponding to the belt body, a fifth ejector (engraved with "B2") corresponding to the buckle, and a sixth ejector (engraved with "B3") corresponding to the staple. The fourth ejector, The top ends of the fifth ejector and the sixth ejector (the end close to the cable tie) are both sheet structures. The fifth ejector slides and fits on the second forming block. The sixth ejector is parallel to the reinforcement rib of the staple and slides through the corresponding third forming block. The fixed mold ejector and the movable mold ejector are respectively arranged on the corresponding fixed mold needle plate and movable mold needle plate through connecting blocks. The connecting blocks are installed through conventional structures such as bolts. A T-shaped slide groove is provided on the side of the connecting block close to the forming cavity. The fixed mold ejector and the movable mold ejector are respectively provided with a T-shaped sliding head that slides in the T-shaped slide groove, and the fixed mold ejector and the movable mold ejector are respectively provided with a T-shaped sliding head that slides in the T-shaped slide groove. They are respectively inclined to the side away from the fixed mold ejector block and the movable mold ejector block, that is, the two fixed mold ejector rods acting on the same fixed mold ejector block and the two movable mold ejector rods acting on the same movable mold ejector block are arranged in an "eight" shape, and the fixed mold lower template and the movable mold template are respectively provided with oblique grooves corresponding to the fixed mold ejector rod and the movable mold ejector rod. When the fixed mold ejector rod and the movable mold ejector rod slide along the corresponding oblique grooves, they can move in a direction parallel to the moving direction of the movable mold and can also gradually disengage from the corresponding fixed mold ejector block and the movable mold ejector block, and the fixed mold ejector pin and the movable mold ejector pin can continue to move relative to the fixed mold ejector block and the movable mold ejector block.

[0065] For example, see Figures 1 to 23 As shown, the fixed mold insert 41 is provided with a flow channel connected to the molding cavity 10 and is connected to the external feeding device, and the fixed mold lower mold plate 3 and the movable mold plate 8 are respectively provided with cooling flow channels connected to the corresponding fixed mold core 4 and movable mold core 9.

[0066] In this technical solution, the cooling channel is a conventional structure, which is used to accelerate the solidification and molding of the cable tie. The injection head of the feeding device such as the external injection molding machine passes through the fixed mold base plate, the fixed mold upper mold plate, the fixed mold ejector plate and the fixed mold lower mold plate and is connected to the runner of the fixed mold top block. The fixed mold top block, the movable mold top block, the fixed mold insert and the movable mold insert are provided with a guide runner connected to the runner on the end face close to the molding cavity. The guide runner is provided with a diverter runner at one end close to the buckle cavity. The diverter runner in the fixed mold top block is connected to the buckle cavity through a connecting hole, which is used to introduce the molten fluid into the molding cavity. The diameter of the connecting hole is less than 2 mm. During the mold opening process, the connection between the waste material and the buckle can be broken by the force of the mold opening. Three seventh ejectors corresponding to the guide runner and the diverter runner are also provided in the movable mold ejector plate for ejecting the waste material connected to the guide runner and the diverter runner.

[0067] The present application also discloses a method for using the cable tie mold, comprising the following steps:

[0068] S1. The molten raw material fluid is injected into the molding cavity through a feeding device such as an injection molding machine, and solidified into a cable tie under the action of a cooling channel;

[0069] S2. The movable mold is driven away from the fixed mold by the machine and the cable tie is demolded. The movable mold pulls the fixed mold ejection mechanism through the opener and shutter. The fixed mold ejector plate drives the fixed mold ejector rod and the fixed mold ejector to move synchronously. The fixed mold ejector rod pushes the fixed mold ejector block to extend out of the fixed mold insert. The cable tie body and the buckle are separated from the fixed mold core plate, and the cable tie support plate is separated from the fixed mold insert. The mold is continued to be opened. The fixed mold ejector rod and the fixed mold ejector block are separated. The fixed mold ejector block stops moving. The fixed mold ejector plate continues to drive the fixed mold ejector to move, and the cable tie staple is separated from the fixed mold ejector block. The cable tie and the fixed mold are completely separated, and the opener and the fixed mold ejection mechanism are disengaged.

[0070] The machine pushes the movable mold ejector plate, which drives the movable mold ejector rod and the movable mold ejector pin. The movable mold ejector rod pushes the movable mold ejector block to extend out of the movable mold inlay. The cable tie body and the buckle are separated from the movable mold core plate, and the cable tie support plate is separated from the movable mold inlay. The movable mold ejector plate continues to move, the movable mold ejector rod and the movable mold ejector block are separated, and the movable mold ejector block stops moving.
