[0036] The embodiments of the utility model will be described below in combination with Figures 1 to 6 .
[0037] As shown in Figure 1 , a specific implementation mode of the sliding block glue injection molding structure provided in the embodiment, comprising: mold core 1, sliding block 2, insert 3 and ejection mechanism.
[0038] Specifically, the mold core 1 has an injection molding surface and a sliding support surface; the sliding block 2 is arranged on the sliding support surface of the mold core 1, and a molding cavity is formed between the sliding block 2 and the injection molding surface of the mold core 1; the sliding block 2 is provided with an injection flow channel, and the injection flow channel has a gate 11; the gate 11 of the injection flow channel is communicated with the molding cavity, and the injection flow channel is adapted to form a flow channel piece 5; the sliding block 2 is also provided with an ejection hole 4, one end of the ejection hole 4 is connected with the injection flow channel, and the other end of the ejection hole 4 penetrates through the bottom surface of the sliding block 2; the insert 3 is slidingly arranged in the ejection hole 4, the top surface of the insert 3 abuts against the flow channel piece 5 formed in the injection flow channel, and the bottom surface of the insert 3 is flush with the bottom surface of the sliding block 2; the ejection mechanism has a push rod 6 slidingly arranged in the mold core 1, and when the sliding block 2 slides to the second position on the sliding support surface, the push rod 6 is opposite to the bottom surface of the insert 3.
[0039] In the embodiment, the mold core 1 has an injection molding surface and a sliding support surface at the same time, which simplifies the overall structure of the injection mold and reduces the wear and error caused by the cooperation of different modules. The mold core 1 and the sliding block 2 jointly form an injection molding cavity, the injection material enters the molding cavity through the gate 11 in the injection flow channel arranged on the sliding block 2, and the injection molding of the part is completed. At the same time, the flow channel system on the sliding block 2 forms a flow channel piece 5, and the bottom surface of the flow channel piece 5 is provided with the insert 3 penetrating through the sliding block 2. After the flow channel piece 5 is formed, the insert 3 is pushed by the ejector rod, and the insert 3 transmits the pushing force to the flow channel piece 5, thereby completing the ejection of the flow channel piece 5 and solving the problem of difficult ejection of the flow channel piece 5 in the injection material structure of the sliding block 2.

[0040] In the embodiment, the sliding cooperation of the sliding block 2 and the mold core 1 not only realizes the flexible formation of the molding cavity, but also makes the injection material enter the molding cavity through the gate 11 to complete the injection molding by the communication between the injection flow channel on the sliding block 2 and the molding cavity, thereby optimizing the arrangement effect of the injection flow channel, reducing the length and volume of the flow channel, and effectively improving the material utilization rate and the quality of the product appearance. After injection molding, the flow channel piece 5 is formed in the injection flow channel and provides a clear ejection path through the ejection hole 4 arranged on the sliding block 2. The insert 3 is slidingly arranged in the ejection hole 4, the top surface of the insert 3 abuts against the flow channel piece 5, and the bottom surface of the insert 3 is flush with the bottom surface of the sliding block 2, thereby effectively preventing the flow channel piece 5 from remaining in the sliding block 2 and ensuring the smoothness of the ejection operation. The push rod 6 is slidingly arranged in the mold core 1 and opposite to the bottom surface of the insert 3 when the sliding block 2 slides to the second position, and the push rod 6 applies a pushing force to the bottom surface of the insert 3, thereby ejecting the flow channel piece 5 from the sliding block 2 and completing the ejection operation.

[0041] As Figure 2 shown, a specific embodiment of the slider 2 glue injection molding structure provided by the present embodiment, the top surface of the insert 3 has a stepped structure, wherein a part of the top surface is flush with the bottom surface of the injection flow channel, and another part of the top surface is flush with the top surface of the slider 2.
[0042] Specifically, the stepped structure is divided into two parts, the higher part is flush with the top surface of the slider 2, and the lower part is flush with the bottom surface of the injection flow channel, and the middle section connecting the two parts closely fits with the side wall of the injection flow channel, and the slider 2 together constitutes the injection flow channel. Through this design, the stepped structure not only can effectively support the flow channel 5, prevent the raw material from flowing into the hole where the insert 3 is located, but also can provide multiple angle thrust force for the flow channel 5, ensure that the flow channel 5 can be smoothly ejected after injection molding.
[0043] As Figure 3 shown, a specific embodiment of the slider 2 glue injection molding structure provided by the present embodiment, the bottom side wall of the ejection hole 4 is provided with a limiting slot 7 extending in the vertical direction, and the insert 3 is provided with a limiting part 8 matched with the limiting slot 7.
[0044] Specifically, the design of the limiting slot 7 ensures the accurate positioning of the insert 3 in the slider 2, avoids the offset or displacement of the insert 3 during injection molding, thereby ensuring the stability and accuracy of the ejection operation of the flow channel 5. The cooperation of the limiting part 8 and the limiting slot 7 enables the insert 3 to slide in the slider 2, providing sufficient control force, ensuring that the insert 3 can effectively transmit thrust to the flow channel 5 during ejection, avoiding possible operation errors or incomplete ejection.
[0045] As Figure 3 shown, a specific embodiment of the slider 2 glue injection molding structure provided by the present embodiment, the bottom surface of the limiting slot 7 extends to the bottom surface of the slider 2, the top surface of the limiting slot 7 is placed inside the slider 2, and the limiting part 8 is fixedly connected to the bottom of the insert 3.
[0046] Specifically, the bottom surface of the limiting slot 7 extends to the position of the bottom surface of the slider 2, so that the limiting part 8 can be accurately positioned in the slider 2, and effectively prevent the insert 3 from moving up and down or left and right in the slider 2. This design enables the insert 3 to remain stable during ejection, avoiding the influence of displacement of the insert 3 on the ejection effect. The limiting part 8 is fixedly connected to the bottom of the insert 3, which not only facilitates the installation of the insert 3 in the slider 2, but also ensures that the combination of the insert 3 and the slider 2 is more firm, further improving the stability and precision of the ejection of the flow channel 5 during injection molding.
[0047] In addition, in other embodiments, the control mode of the longitudinal movement of the insert 3 can also be selected to set a locking device or a mechanical buckle between the slider 2 and the insert 3, and after the ejection is completed, the locking mechanism can be used to fix the insert 3 to prevent the insert 3 from moving longitudinally or being displaced, thereby ensuring the accuracy of the ejection process.
[0048] As shown in Figure 4 , a specific embodiment of the injection molding structure provided by the slider 2 is provided, the injection molding flow channel includes a main flow channel 9, a plurality of branch flow channels 10, and a sprue 11, the main flow channel 9 extends in a first direction on the slider 2, the plurality of branch flow channels 10 are in communication with the main flow channel 9 respectively, and one end of the sprue 11 is connected to the end of the branch flow channel 10, and the other end of the sprue 11 is connected to the cavity.
[0049] Specifically, the connection of the main flow channel 9 and the two branch flow channels 10 can ensure that the injection molding material flows uniformly and smoothly into the cavity, avoiding uneven injection or molding defects caused by unreasonable flow channel layout. The material waste and temperature unevenness caused by excessive heating or excessive cooling of a single flow channel are effectively avoided, the overall injection molding process is optimized, and the production efficiency is improved.
[0050] It should be noted that the number of branch flow channels 10 is not limited in the embodiment, and as long as a corresponding insert 3 is provided below the corresponding branch flow channel 10, the insert 3 can be independently provided below each branch flow channel 10, thereby ensuring the smooth ejection of the flow channel part 5.
[0051] As shown in Figure 4 , a specific embodiment of the injection molding structure provided by the slider 2 is provided, the insert 3 has a plurality of inserts 3 arranged below the main flow channel 9 and each branch flow channel 10.
[0052] Specifically, the insert 3 is arranged below the main flow channel 9 and each branch flow channel 10, and provides uniform support for the flow channel part 5 by contacting the flow channel part 5. This design ensures that the flow channel part 5 can receive uniform thrust during the ejection process, thereby avoiding the phenomenon of jamming or incomplete ejection caused by uneven thrust.
[0053] As shown in Figure 5 , a specific embodiment of the injection molding structure provided by the slider 2 is provided, the push rod 6 is in one-to-one corresponding cooperation with the insert 3.
[0054] Specifically, the push rod 6 is placed below the slider 2 through the mold pin 1, and the mold pin 1 provides a certain guiding effect for the linear motion of the push rod 6. After the slider 2 slides after injection molding is completed, the push rod 6 is tightly matched with the bottom surface of each insert 3, so as to ensure that the push rod 6 can accurately act on the insert 3, and the pushing force is uniformly transmitted to the runner 5 through the insert 3, thereby realizing smooth ejection of the runner 5.
[0055] As shown in Figure 6 , it is a specific embodiment of the injection molding structure of the slider 2 provided in the embodiment, and the upper surface of the slider 2 is also provided with a guide column hole, and the guide column hole cooperates with the shovel base 12 to control the movement of the slider 2.
[0056] Specifically, the shovel base 12 can accurately control the movement path and position of the slider 2 in the mold through the guiding effect of the guide column. The guide column hole provides necessary positioning and guiding effect for the smooth movement of the slider 2, avoids deviation or jamming of the slider 2 during movement, ensures the stability and accuracy of the slider 2 during the entire injection molding process, and provides a basis for the accurate cooperation of the push rod 6 and the insert 3.
[0057] As shown in Figure 6 , it is a specific embodiment of the injection molding structure of the slider 2 provided in the embodiment, and the slider 2 is symmetrically provided with two pressing blocks 13 on both sides, and the pressing block 13 is in abutment with the side surface of the slider 2.

[0060] Specifically, the protruding block is placed at the bottom of both sides of the slider 2, the extension direction of the protruding block is the same as the movement direction of the slider 2, and the cooperation of the guiding space and the protruding block ensures that the protruding block on the side surface of the slider 2 will not be jammed or deviated during sliding, so that the movement of the slider 2 in the mold is more stable.
[0061] Working principle:
[0062] The slider 2 and the mold core 1 jointly form an injection molding cavity, and the injection material enters the cavity through the injection flow channel arranged on the slider 2 to be molded. After the injection material is cooled and solidified, the slider 2 is driven by the shovel base 12 to slide along the guide track, and at the same time, the pressing blocks 13 on both sides provide stable guiding effect, so as to ensure that the slider 2 and the mold core 1 are smoothly separated. In this process, the push rod 6 located below the slider 2 is accurately aligned with the insert 3 inside the slider 2, the push rod 6 pushes up the insert 3, the insert 3 contacts the flow channel piece 5 to provide a pushing force to the flow channel piece 5, so that the flow channel piece 5 is separated from the injection flow channel. The limiting block of the insert 3 cooperates with the limiting groove 7 in the slider 2, so as to ensure that the flow channel piece 5 reaches a proper height during the ejection process, and the ejection operation of the flow channel piece 5 is smoothly completed. This process effectively improves the stability and accuracy of the injection molding process, reduces the waste of raw materials, and ensures the appearance quality and process efficiency of the product.
