Description
Technical Field
[0001] This application relates to the field of injection molding technology, and in particular to an auxiliary installation fixture for a nail gate lower cover. Background Technology
[0002] Insert injection molding is an integrated process in which prefabricated inserts (such as metal parts) are placed into an injection mold and then encapsulated and molded by injecting molten plastic. Its core processes include insert pretreatment, precise positioning, mold closing and injection molding, and cooling and shaping, ultimately forming a composite product that combines the functionality of the insert with the structural strength of the plastic.
[0003] Reference Figure 1 When the insert injection molded workpiece 6 is a lower cover of a nail gate, the workpiece 6 needs to be placed into the mold 1. The mold 1 has an injection cavity 5, and two first positioning blocks 3 and one second positioning block 4 are installed in the injection cavity 5. A positioning rod 2 is installed on the mold 1. The workpiece 6 is about 4mm wide and about 4cm long. One end of the workpiece 6 has a round hole 11. The mold 1 has multiple insertion holes 7. When performing insert injection molding on the lower cover of the nail gate, the workpiece 6 is first placed in the injection cavity 5. At this time, the two first positioning blocks 3 position the two sides of the workpiece 6, the positioning rod 2 is inserted into one end of the workpiece 6 through the round hole 11 for positioning, and the second positioning block 4 positions the end of the workpiece 6 away from the round hole 11.
[0004] After the insert is injection molded, the workpiece needs to be removed and a new workpiece needs to be placed into the injection cavity. Because the workpiece is small, it is difficult to align it with the round hole and position it using the first and second positioning blocks. Moreover, the temperature is high when the mold is completed, and operators are prone to burns when performing the above operations. Utility Model Content
[0005] To facilitate the handling of workpieces and ensure the safety of operators, this application provides an auxiliary installation fixture for nailing the lower cover of a gate.
[0006] The auxiliary installation fixture for a gate cover provided in this application adopts the following technical solution:
[0007] An auxiliary installation fixture for a gate cover includes a pressure plate, a mounting plate, a mounting block, an elastic element, a push rod, and multiple insert rods. The multiple insert rods are disposed on the pressure plate. The mounting plate is slidably disposed on the multiple insert rods. The ends of the insert rods away from the pressure plate are inserted into insertion holes in a mold. The two ends of the elastic element abut against the pressure plate and the mounting plate, respectively. The mounting block is disposed on the mounting plate and located on the top wall of the mounting plate away from the pressure plate. A receiving groove is formed on the mounting block, and the workpiece is placed in the receiving groove. One end of the push rod is disposed on the pressure plate, and the other end of the push rod passes through the mounting plate and the mounting block and slidably abuts against the workpiece.
[0008] By adopting the above technical solution, after the workpiece is inserted and molded, it is removed and a new workpiece is placed into the injection cavity. The operator places the workpiece in the receiving slot of the auxiliary mounting fixture on the lower cover of the pin gate, inserts the insert rod into the mold's insertion hole, and the mounting plate abuts against the mold, aligning the receiving slot of the mounting block with the injection cavity of the mold. By pressing the pressure plate towards the mold, the pressure plate pushes the spring to contract, and the pressure plate drives the ejector rod to move. The ejector rod moves within the mounting block and pushes the workpiece from the receiving slot into the injection cavity, thus completing the placement of the workpiece. The pressure plate is then released, and the elastic element pushes the pressure plate to move back to its original position. This design facilitates workpiece replacement even when the mold temperature is high, preventing burns and improving work efficiency.
[0009] Preferably, a pressure block is detachably provided on the side wall of the pressure plate near the mounting plate, and two push rods are provided, which are detachably provided in the pressure block and are located at both ends of the workpiece length direction.
[0010] By adopting the above technical solution, two ejector rods simultaneously push the workpiece to move from both ends along the length of the workpiece, thereby facilitating the movement of the workpiece from the receiving groove into the injection cavity. At the same time, the ejector rods are detachable, making it easy to replace them.
[0011] Preferably, there is a clearance between the top end of the push rod and the workpiece.
[0012] By adopting the above technical solution, a certain floating space is left between the ejector rod and the workpiece, so that the workpiece is not likely to fall out of the receiving groove due to accidental contact before the mounting fixture is installed on the mold.
[0013] Preferably, one of the push rods slides through the circular hole of the workpiece, and the top end of the push rod passing through the circular hole of the workpiece is provided with a clearance hole.
[0014] By adopting the above technical solution, when the ejector rod moves the workpiece from the receiving groove to the injection cavity, the positioning rod of the mold is inserted into the clearance hole of the ejector rod, so that the workpiece can smoothly enter the injection cavity of the mold.
[0015] Preferably, a connecting rod is fixedly provided on the side of the mounting plate near the pressure plate, and a sliding groove is provided on the side of the pressure plate away from the mounting plate. The connecting rod passes through the pressure plate and extends into the sliding groove. A connector is provided at the end of the connecting rod, and the connector is slidably disposed in the sliding groove.
[0016] By adopting the above technical solution, when the pressure plate moves, the connecting rod drives the connecting head to move in the slide groove. The connecting rod limits the mounting plate through the connecting head and the slide groove, so that the mounting plate will not slip off the insert rod.
[0017] Preferably, the pressure plate has a second receiving hole on the side wall near the mounting plate, the mounting plate has a first receiving hole on the side wall near the pressure plate, and the two ends of the elastic member are respectively disposed in the first receiving hole and the second receiving hole.
[0018] By adopting the above technical solution, the first and second receiving holes limit the two ends of the elastic element, making the elastic element's expansion and contraction deformation more stable.
[0019] Preferably, the mounting block has a chamfer at the opening of the receiving groove.
[0020] By adopting the above technical solution, the chamfer on the opening of the receiving groove allows the workpiece to fit smoothly into the receiving groove, making it easier for operators to operate and improving work efficiency.
[0021] Preferably, the pressure plate has grooves on both sides of its width direction.
[0022] By adopting the above technical solution, the contact area between the operator's fingers and the pressure plate is increased through the grooves on both sides of the pressure plate, thereby increasing the friction force. This facilitates the use of auxiliary installation fixtures for the lower cover of the nail gate and ensures the safety of the operator.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. Using a pressure plate, after the insert molding of a workpiece is completed, the workpiece is removed, and a new workpiece is placed into the injection cavity. The operator places the workpiece in the receiving slot of the auxiliary mounting fixture on the lower cover of the pin gate, inserts the insert rod into the mold's insertion hole, and the mounting plate abuts against the mold, aligning the receiving slot of the mounting block with the injection cavity of the mold. By pressing the pressure plate towards the mold, the pressure plate pushes the spring to contract, and the pressure plate drives the ejector rod to move. The ejector rod moves within the mounting block and pushes the workpiece from the receiving slot into the injection cavity, thus completing the workpiece placement. The pressure plate is then released, and the elastic element pushes the pressure plate back to its original position. This design facilitates workpiece replacement smoothly when the mold temperature is high, avoiding burns and improving work efficiency.
[0025] 2. With the help of a pressure block and two ejector rods, the two ejector rods simultaneously push the workpiece from both ends along its length, thereby facilitating the movement of the workpiece from the receiving groove into the injection cavity. At the same time, the ejector rods are detachable, making it easy to replace them.
[0026] 3. By opening a clearance hole, when the ejector pin moves the workpiece from the receiving groove to the injection cavity, the positioning pin of the mold inserts into the clearance hole of the ejector pin, so that the workpiece can smoothly enter the injection cavity of the mold.

[0033] The following is in conjunction with the appendix Figures 2-5 This application will be described in further detail.
[0034] Reference Figure 2 and Figure 3 An auxiliary installation fixture for a nail gate cover includes a pressure plate 8 and a mounting plate 9. Four insert rods 12 are fixedly installed on the pressure plate 8. The four insert rods 12 are located at the four corners of the pressure plate 8, and the four insert rods 12 slide through the mounting plate 9 and are inserted into the insertion holes 7 of the mold 1.
[0035] Reference Figure 3 and Figure 4 A pressure block 17 is detachably fixed to the side wall of the pressure plate 8 near the mounting plate 9 by bolts. Four push rods 14 are inserted into the pressure block 17, and the four push rods 14 are located at the four corners of the pressure block 17. Two mounting blocks 10 are installed on the side wall of the mounting plate 9 away from the pressure plate 8. Each mounting block 10 has a receiving groove 16 on its side wall away from the mounting plate 9. The receiving groove 16 is used to place the workpiece 6. The mounting block 10 has a chamfer 25 at the opening of the receiving groove 16. The chamfer 25 allows the workpiece 6 to be smoothly placed into the receiving groove 16, which is convenient for the operator.
[0036] Reference Figure 2 , Figure 3 and Figure 5The ends of the four push rods 14 furthest from the pressure plate 8 slide through the mounting plate 9. The ends of every two push rods 14 are inserted into a mounting block 10. The push rods 14 can move into the receiving grooves 16, and the two push rods 14 are located at opposite ends of the workpiece 6 along its length. Four first receiving holes 23 are formed on the side wall of the mounting plate 9 near the pressure plate 8, and four second receiving holes are formed on the side wall of the pressure plate 8 near the mounting plate 9. The positions of the four first receiving holes 23 correspond to the positions of the second receiving holes. Four elastic elements 13 are installed between the pressure plate 8 and the mounting plate 9. One end of each elastic element 13 is located in a first receiving hole 23, and the other end is located in a second receiving hole. In this application, the elastic elements 13 can be springs.
[0037] After the insert injection molding of workpiece 6 is completed, the finished workpiece 6 is first removed, and then the new workpiece 6 is placed into the receiving groove 16 of the mounting fixture. The mounting fixture is moved so that the four insert rods 12 are respectively inserted into the four insertion holes 7 of the mold 1. At this time, the mounting plate 9 abuts against the mold 1, and the receiving grooves 16 of the two mounting blocks 10 correspond to the two injection cavities 5 of the mold 1.
[0038] After positioning is completed, the pressure plate 8 is pressed towards the mold 1, and the pressure plate 8 squeezes the elastic element 13. At the same time, the pressure plate 8 drives the four push rods 14 to move through the pressure block 17. The four push rods 14 move to abut against the two workpieces 6 and push the two workpieces 6 from the receiving groove 16 into the injection cavity 5 of the mold 1.
[0039] After the workpiece 6 enters the injection cavity 5 of the mold 1, the pressure plate 8 is released, and the elastic element 13 pushes the pressure plate 8 to move and reset, thus completing the automatic placement of the workpiece 6. This allows the operator to smoothly complete the workpiece 6 replacement when the temperature of the mold 1 is high, avoiding burns and improving work efficiency.
[0040] There is a clearance 18 between the end of the ejector pin 14 and the workpiece 6, which leaves a certain floating space between the ejector pin 14 and the workpiece 6, so that the workpiece 6 is not likely to fall out of the receiving groove 16 due to accidental contact before the mounting fixture is installed on the mold 1.
[0041] In the two ejector rods 14 inserted into the mounting block 10, the end sections of the two ejector rods 14 are rectangular and circular, respectively. The end of the ejector rod 14 with the circular cross-section has a clearance hole 19, which is used to avoid the positioning rod 2 of the mold 1. When the ejector rod 14 moves the workpiece 6 from the receiving groove 16 into the injection cavity 5, the positioning rod 2 of the mold 1 inserts into the clearance hole 19 of the ejector rod 14, so that the workpiece 6 can smoothly enter the injection cavity 5 of the mold 1.
[0042] Two connecting rods 20 are fixedly installed on the side wall of the mounting plate 9 near the pressure plate 8, with the two connecting rods 20 located at both ends along the length of the mounting plate 9. Connecting heads 22 are installed at the ends of the connecting rods 20, and the diameter of the connecting heads 22 is larger than the diameter of the connecting rods 20. Two sliding grooves 21 are formed on the side of the pressure plate 8 away from the mounting plate 9, located at both ends along the length of the pressure plate 8. The two connecting rods 20 pass through the pressure plate 8 and extend into the sliding grooves 21, and the two connecting heads 22 slide within the sliding grooves 21.
[0043] When the elastic element 13 moves the pressure plate 8 to reset, the connector 22 slides in the slide groove 21. After the pressure plate 8 completes the reset, the connector 22 moves to the end of the slide groove 21. At this time, the connector 22 limits the mounting plate 9 through the connecting rod 20, so that the mounting plate 9 will not slip off the insert rod 12.
[0044] The implementation principle of the auxiliary installation fixture for a gate lower cover according to this application embodiment is as follows: After the workpiece 6 completes the insert injection molding, the workpiece 6 is removed, and a new workpiece 6 is placed into the injection cavity 5. The operator places the workpiece 6 in the receiving groove 16 of the auxiliary installation fixture for the gate lower cover, inserts the insertion rod 12 into the insertion hole 7 of the mold 1, and the mounting plate 9 abuts against the mold 1, so that the receiving groove 16 of the mounting block 10 is aligned with the injection cavity 5 of the mold 1. By pressing the pressure plate 8 towards the mold 1, the pressure plate 8 pushes the spring to contract, and the pressure plate 8 drives the push rod 14 to move. The push rod 14 moves within the mounting block 10 and pushes the workpiece 6 from the receiving groove 16 to the injection cavity 5, thus completing the placement of the workpiece 6. Then, the pressure plate 8 is released, and the elastic element 13 pushes the pressure plate 8 to move and reset. This facilitates the operator to smoothly complete the workpiece 6 replacement work when the temperature of the mold 1 is high, avoids burns, and improves work efficiency.

Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
