Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features.

[0064] In this application, unless otherwise expressly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0065] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0066] Example:

[0067] like Figures 1-7 As shown in the figure, this application discloses an injection mold for a conveyor handle accessory, the specific structure of which includes: a top plate 1, an upper mold sleeve 2, multiple flow-cutting structures 3, an upper mold core 4, a lower mold sleeve 5, a lower mold core 6, two side plates 7, a bottom plate 8, and a lifting mechanism 9.

[0068] The top plate 1 is provided with an injection runner 101, which is used to guide molten plastic material from the nozzle of the injection molding machine into the mold. The top plate 1 is preferably composed of two plates, upper and lower, which facilitates production, manufacturing and maintenance.

[0069] The upper mold sleeve 2 is located on the lower side of the top plate 1 and can fit tightly with the top plate 1. The top surface is provided with a transfer groove 201 and multiple branch flow channels 202. The transfer groove 201 corresponds to the injection flow channel 101 and is connected to each branch flow channel 202, so that the plastic material can flow smoothly from the transfer groove into each branch flow channel 202.

[0070] A plurality of flow interception structures 3 are embedded in the top surface of the upper mold sleeve 2 and correspond to the branch flow channels 202 one by one, which can cut off the flow of plastic material, so as to control the accurate flow of plastic material to the required molding space.

[0071] The upper mold core 4 is embedded in the bottom surface of the upper mold sleeve 2, and a plurality of upper cavities 401 are opened in the bottom surface, which correspond to and communicate with the branch flow channels 202, and are used to form the upper half of the conveyor handle accessory.

[0072] The lower mold sleeve 5 is located below the upper mold sleeve 2 and serves as a support structure of the lower mold core 6.

[0073] The lower mold core 6 is embedded in the top surface of the lower mold sleeve 5, and a plurality of lower cavities 601 are opened in the top surface, which are used to form the lower half of the conveyor handle accessory and correspond to the upper cavities 401; therefore, when the upper and lower mold cores are closed, the upper cavities 401 and the lower cavities 601 jointly form a complete molding space.

[0074] Two side plates 7 are installed on the bottom surface of the lower mold sleeve 5 and serve as the installation basis of the jacking mechanism 9.

[0075] The bottom plate 8 is installed on the bottom surface of the two side plates 7 and provides a stable base for the entire mold.

[0076] The jacking mechanism 9 is arranged between the two side plates 7 and is responsible for ejecting the molded conveyor handle accessory from the mold after the injection is completed, which facilitates the subsequent picking and preparation for the next round of injection.

[0077] It should be noted that the top plate 1 and the upper mold sleeve 2 are attached to each other when the mold is closed and are separated from each other when the mold is opened; this not only ensures that the plastic material can flow stably into the molding space when the mold is closed, but also facilitates the cleaning and removal of the material in the branch flow channels 202, thereby avoiding the mutual interference between the plastic materials.

[0078] The above technical solution takes two molding spaces as an example for illustration, and the working mode is as follows:

[0079] When performing one molding of the conveyor handle accessory:

[0080] Step one, the top plate 1, the upper mold sleeve 2 and the lower mold sleeve 5 are separated from each other, at this time the flow interception structure 3 corresponding to the molding space A is opened, and the upper mold core 4 corresponding to the molding space B is closed.

[0081] Step two, perform the mold closing operation, so that the top plate 1, the upper mold sleeve 2 and the lower mold sleeve 5 remain attached to each other, at this time the branch flow channels 202 are tightly closed by the top plate 1, thus avoiding the leakage of plastic material, and the upper cavities 401 and the lower cavities 601 are combined to form a complete molding space.

[0082] Step three, injection molding operation is carried out, so that the plastic material from the injection flow channel 101 into the transfer tank 201, and then into two branch flow channel 202, at this time due to the setting of step one, so the branch flow channel 202 corresponding to the forming space B is cut off, so that the plastic material can only flow into the forming space A, so as to complete the conveyor handle accessory one-time molding.

[0083] Step four, the mold is opened, so that the top plate 1, the upper mold sleeve 2 and the lower mold sleeve 5 are kept apart, and then the material in the transfer tank 201 and the branch flow channel 202 can be cleaned and removed to avoid blocking the flow channel.

[0084] Step five, the ejection operation is carried out, so that the lifting mechanism 9 can eject the molded conveyor handle accessory from the mold, which is convenient for subsequent part taking and preparation for the next injection molding.

[0085] When the conveyor handle accessory is molded for the second time, most of the steps are the same as the above-mentioned one-time molding, and the difference is only that the flow cutting structure 3 corresponding to the forming space A is closed in advance, and the upper mold core 4 corresponding to the forming space B is opened, and the one-time molding product needs to be placed in the forming space B before each mold closing.

[0086] The utility model discloses a plurality of branch flow channels 202 are communicated with the transfer tank 201, and the branch flow channel 202 is controlled by the flow cutting structure 3, so that the same mold can be used for producing the injection molding product molded for multiple times, which greatly reduces the cost of mold manufacturing, and can reduce the mold replacement and debugging time, thereby shortening the production cycle of the product and improving the production efficiency.

[0087] In some embodiments, as shown in Figure 3 To improve the operation automation, a plurality of opening and closing plugs 10 and a plurality of limiting rods 11 are further included, which are arranged as follows:

[0088] The plurality of opening and closing plugs 10 are installed on the top surface of the lower mold sleeve 5.

[0089] The plurality of limiting rods 11 are vertically arranged and installed on the bottom surface of the top plate 1, and each limiting rod 11 includes a rod body 1101 and a stop block 1102 arranged at the bottom end of the rod body 1101.

[0090] The bottom surface of the upper mold sleeve 2 is provided with a plurality of accommodating grooves 203, which correspond to the opening and closing plugs 10 and can be interference-fitted, the top surface of the lower mold sleeve 5 is provided with a plurality of accommodating holes 501 matched with the limiting rods 11, and the bottom surface of the upper mold sleeve 2 is provided with a plurality of second-order through holes 204 matched with the limiting rods 11.

[0091] It should be noted that when the mold is closed, the accommodating hole 501 can accommodate the limiting rod 11, ensuring that it can stably play a role and will not interfere with the movement of the mold. The opening and closing plug 10 is inserted into the corresponding accommodating groove 203 and forms an interference fit.

[0092] When the mold is opened, the top plate 1 remains stationary, and the bottom plate 8 moves away from the top plate 1 under the action of the driving mechanism. Thus, the bottom plate 8 drives the lower mold sleeve 5 to move, and the lower mold sleeve 5 drives the upper mold sleeve 2 to move together through the opening and closing plug 10, so that the top plate 1 and the upper mold sleeve 2 gradually separate until the stop block 1102 and the second-order through hole 204 form a limiting engagement. Thereafter, the lower mold sleeve 5 continues to descend and drives the opening and closing plug 10 to disengage from the accommodating groove 203.

[0093] Through the above setting, the top plate 1 and the upper mold sleeve 2 can be separated during mold opening, thereby facilitating the cleaning and removal of the material punching in the branch runner 202, and thus improving the production efficiency.

[0094] In some embodiments, as shown in Figure 6 The upper surface of the upper mold sleeve 2 is provided with a plurality of limiting sliding grooves 205, and the limiting sliding grooves 205 correspond one by one and transversely cut off the branch runner 202.

[0095] In this embodiment, the flow cutting structure 3 includes a locking block 301, a bolt 302, and a sliding bar 303, which are specifically provided as follows:

[0096] The locking block 301 is arranged in the limiting sliding groove 205, and a strip-shaped hole 3011 is formed in the top surface thereof;

[0097] The bolt 302 passes through the strip-shaped hole 3011 and is threadedly connected to the groove bottom of the limiting sliding groove 205;

[0098] The sliding bar 303 is arranged in the limiting sliding groove 205 and is fixedly connected with the locking block 301, and a horizontal groove 3031 is formed in the top surface thereof.

[0099] When it is necessary to cut off the branch runner 202, the bolt 302 is loosened, and then the sliding bar 303 is pushed to slide in the limiting sliding groove 205 until the horizontal groove 3031 is misaligned with the branch runner 202. Then the bolt 302 is tightened again so that the locking block 301 is locked and fixed.

[0100] Through the above design of the flow cutting structure 3, the flow of plastic material can be simply and conveniently cut off, and the structure is simple and compact, facilitating production and manufacturing.

[0101] In some embodiments, as shown in Figure 2 and Figure 4 The jacking mechanism 9 includes a plurality of guide columns 901, a first push plate 902, a second push plate 903, a plurality of sets of ejector pins 904, and a butt joint screw sleeve 905, which are provided as follows:

[0102] A plurality of guide columns 901 are arranged between the lower die sleeve 5 and the bottom plate 8, for providing stable sliding guide, ensuring smoothness and accuracy during the jacking process;

[0103] The first push plate 902 is slidingly sleeved on the guide column 901, serving as the mounting base of the ejector pin 904;

[0104] The second push plate 903 is slidingly sleeved on the guide column 901 and is fixed to the bottom surface of the first push plate 902, together with the first push plate 902 forming the main body of the jacking mechanism 9;

[0105] A plurality of ejector pins 904 are mounted on the top surface of the first push plate 902 and correspond to the lower cavities 601 one by one, and can be inserted into the corresponding lower cavities 601 upward, for ejecting the completed products from the mold;

[0106] The butt joint screw 905 is mounted on the bottom surface of the second push plate 903, which serves as the interface for connecting with the external jacking power device, so as to transmit power to the second push plate 903, thereby driving the whole jacking mechanism 9 to work.

[0107] The bottom plate 8 is provided with a connecting through hole 801 corresponding to the butt joint screw 905, for providing a necessary channel for the connection of the butt joint screw 905 with the external jacking power device.

[0108] Through the above design of the jacking mechanism 9, stable sliding guide is provided by the guide column 901, the jacking force is transmitted through the cooperative action of the first push plate 902 and the second push plate 903, the completed products are ejected from the mold through the ejector pin 904, and the butt joint screw 905 is connected with the external jacking power device, realizing the whole jacking process, which makes the mold opening and product taking process more convenient and efficient, and improves the production efficiency.

[0109] On the basis of the above embodiment, as shown in Figure 2 The jacking mechanism 9 further comprises a plurality of first guide rods 906 and a plurality of reset springs 907, which are arranged as follows:

[0110] The plurality of first guide rods 906 are mounted on the top surface of the first push plate 902 and penetrate the lower die sleeve 5 upward, for providing support for the reset springs 907 to avoid twisting and deflection;

[0111] The plurality of reset springs 907 are correspondingly movably sleeved on the first guide rods 906 and are constrained between the lower die sleeve 5 and the bottom plate 8.

[0112] When the jacking mechanism 9 is working, the first push plate 902 gradually rises, so that the reset spring 907 is gradually compressed, and when the external jacking power device releases the pressure, the rebound force of the reset spring 907 pushes the first push plate 902 back to the original position, thereby preparing for the next injection molding process.

[0113] Through the above setting, not only the degree of automation of the jacking mechanism 9 is improved, but also the stability and reliability of the mold in the continuous production process are ensured, and a certain buffering effect is achieved, which reduces the impact and wear of the jacking mechanism 9 on the mold during the working process, and prolongs the service life of the mold.

[0114] On the basis of the above embodiment, as shown in Figure 2 and Figure 5 , the jacking mechanism 9 further comprises a third push plate 908, a plurality of opening and closing columns 909, a plurality of stop columns 910, a plurality of jacking columns 911 and a plurality of forming blocks 912, which are arranged as follows:

[0115] The third push plate 908 is slidably sleeved on the guide column 901 and the butt joint screw 905, and a plurality of accommodation grooves 9081 are formed on the top surface thereof;

[0116] The plurality of opening and closing columns 909 are installed on the bottom surface of the second push plate 903, and correspond to the accommodation grooves 9081 and can be interference fitted;

[0117] The plurality of stop columns 910 are installed on the bottom surface of the lower mold sleeve 5, and can penetrate the first push plate 902 and the second push plate 903 downward;

[0118] The plurality of jacking columns 911 are installed on the top surface of the third push plate 908, and are inserted into the corresponding lower cavity 601 after penetrating the first push plate 902 and the second push plate 903;

[0119] The plurality of forming blocks 912 are installed one by one on the top end of the jacking column 911 and are located in the lower cavity 601.

[0120] It should be noted that, as shown in Figure 8 , since the one-time forming part of the conveyor handle auxiliary part is a ring structure, it is relatively difficult to take out after forming, therefore, by setting the forming block 912, it can not only cooperate with the injection molding, but also assist in ejection and discharging.

[0121] When the jacking mechanism 9 is working, the first push plate 902 gradually rises, thereby driving the second push plate 903 to move together, and the second push plate 903 drives the third push plate 908 to rise synchronously through the opening and closing column 909, and the third push plate 908 drives the forming block 912 to rise through the jacking column 911, thereby cooperating with the ejector pin 904 to eject the one-time formed product from the mold; after the third push plate 908 rises to abut against the stop column 910 passing through the first push plate 902 and the second push plate 903, it is blocked; then the opening and closing column 909 and the mounting groove 9081 gradually disengage, thereby enabling the first push plate 902 and the second push plate 903 to continue to rise, so as to push the one-time formed product to disengage from the forming block 912 through the ejector pin 904.

[0122] Through the above design, the smoothness of product demolding is improved, the quality of the product is guaranteed, and the product is prevented from being damaged in the ejection process.

[0123] In some embodiments, as shown in Figure 3 , further comprising: a plurality of second guide columns 12 installed on the bottom surface of the top plate 1 and penetrating downward through the upper die sleeve 2 and the lower die sleeve 5, and capable of being inserted into the side plate 7.

[0124] During the closing and opening of the mold, the second guide column 12 ensures that the upper die sleeve 2 and the lower die sleeve 5 can move smoothly along the predetermined track, avoids damage to the mold or product defects caused by misalignment or inclination, and also plays a positioning role, ensuring that each part of the mold can be accurately aligned during assembly.

[0125] In some embodiments, as shown in Figure 1 , further comprising: a locking strip 13 arranged vertically, and the upper end is detachably connected with the top plate 1, and the lower end is detachably connected with the lower die sleeve 5.

[0126] For example, long holes are formed at both ends of the locking strip 13, and locking bolts pass through the long holes and are threadedly connected with the top plate 1 or the intercepting structure 3.

[0127] Through the above setting, uniform locking force can be provided, ensuring that each part of the mold can be tightly combined together, thereby preventing molten plastic from leaking or generating flash during injection molding, thereby ensuring the quality of the product and the stability of the production process.
