Description

Technical Field

[0001] This application relates to a mold structure with quick-release inserts and a method for assembling and disassembling the inserts in the field of mold technology. Background Technology

[0002] In the field of injection molding manufacturing, molds are essential equipment in the processing. To better shape the workpiece or to change specific details as needed, inserts are often installed in the center of the mold. Inserts are irregular mold components embedded in the mold, serving to fix the mold plate and fill the space between it. By replacing inserts of different shapes, specific details of the workpiece can be modified without designing an entire set of molds for a particular type of workpiece, thus saving production costs.

[0003] Currently, inserts are generally connected by bolts, which can be used to remove and fix the inserts. Since the front of the mold needs to fit the workpiece, in order to avoid the screw holes affecting the workpiece forming, the inserts are generally inserted from the back of the mold and exposed from the front. The bolts also extend from the back of the mold and connect the inserts to the mold as a whole.

[0004] However, since the injection molding machine is usually connected to the back of the mold, the fixing bolts of the insert are obscured by the machine after the mold is installed, making them impossible to remove. Replacing the insert requires first removing the entire mold from the injection molding machine before the insert can be removed from the back of the mold, a very cumbersome operation. Furthermore, because the insert is tightly fitted to the mold, even after loosening the bolts, workers still need to use force to pull the insert out of the mold. Sometimes, it is even necessary to tap the protruding insert from the front of the mold to detach it, which is time-consuming, laborious, and can easily damage the insert surface in the process.

[0005] Application content

[0006] The purpose of this application is to at least solve one of the technical problems existing in the prior art, and to provide a mold structure with quick-release inserts and a method for removing and installing inserts, which can remove and replace inserts when the mold and injection molding machine are in the installation state.

[0049] Currently, inserts are generally connected using bolts, allowing for both removal and installation by tightening the bolts. Since the front of the mold needs to fit snugly against the workpiece, to avoid the screw holes affecting workpiece molding, inserts are typically inserted from the back of the mold and protrude from the front. The bolts also extend from the back of the mold, connecting the insert to the mold as a single unit. However, because the injection molding machine is usually also connected to the back of the mold, the insert's fixing bolts are obscured by the machine after the mold is installed, making removal impossible. Replacing the insert requires first removing the entire mold from the injection molding machine before the insert can be removed from the back, a very cumbersome process. Furthermore, because the insert is tightly fitted to the mold, even after loosening the bolts, workers still need to forcefully pull the insert out of the mold. Sometimes, it's even necessary to tap the protruding insert from the front of the mold to detach it, which is time-consuming, laborious, and can easily damage the insert's surface in the process.

[0050] In response, this application proposes a mold structure with quick-release inserts and a method for insert assembly and disassembly. By opening a channel on the side of the mold 100, the insert 300 can enter from the side of the mold 100 without first removing the mold 100 from the injection molding machine, reducing assembly and disassembly steps and alleviating labor burden. Moreover, by changing the insertion posture of the fixing member 400, the limiting block 410 can abut against the first inner wall 311 when fixing the insert 300, and apply force to the second inner wall 312 when removing the insert 300, serving two purposes and making the assembly and disassembly of the insert 300 more convenient.

[0051] Reference Figure 1 The mold structure with quick-release insert in the first aspect embodiment of this application includes a mold 100, a mounting component 200, an insert 300, a fixing component 400, and fixing bolts 500. The mold 100 is the main structure of this mold structure with quick-release insert, with a mold core for shaping the workpiece on its front side and a back side for connecting to an injection molding machine. (See reference...) Figure 2 The mold 100 has a first slide groove 110, a second slide groove 120 and a third slide groove 130. The first slide groove 110 extends to the back of the mold 100 and has a through hole 111 at its bottom. The second slide groove 120 and the third slide groove 130 are connected to the first slide groove 110 and extend to the side of the mold 100.

[0052] The mounting component 200 is detachably connected to the mold 100, specifically by inserting it into the mold 100 through the first groove 110 and fixing it to the mold. In this embodiment, the mounting component 200 is fixed to the mold 100 by bolts.

[0053] Insert 300 enters the first slide groove 110 through the second slide groove 120. The end of insert 300 protrudes from the front of mold 100 through through hole 111, thus shaping the workpiece together with the mold core on the front of mold 100. When adjustments to local details of the workpiece are required, insert 300 can be removed and replaced, allowing this mold structure with quick-release inserts to adapt to more application scenarios. It is worth noting that, according to reference... Figure 4 ( Figure 4 a is a 3D drawing of the inlay 300. Figure 4 (b is a cross-sectional view of the insert 300). The insert 300 has a through square hole 310. The square hole 310 includes a first inner wall 311 near the front of the mold 100 and a second inner wall 312 near the back of the mold 100. Both the first inner wall 311 and the second inner wall 312 are inclined surfaces.

[0054] The fastener 400 is inserted through the third slide groove 130, as shown in the reference. Figure 5 ( Figure 5 a is a 3D view of fastener 400. Figure 5 (b is a cross-sectional view of the fastener 400), which has a limiting block 410 at its end. One side of the limiting block 410 is inclined and can abut against the first inner wall 311 or the second inner wall 312. The fixing bolt 500 can pass through the square hole 310 of the fastener 400 and the insert 300 in sequence and be threadedly connected to the mounting part 200, thereby fixing the three together.

[0055] The working principle of this mold structure with quick-release inserts is as follows: When insert 300 needs to be installed, the fixing member 400 is inserted into the third slide groove 130. The limiting block 410 of the fixing member 400 abuts against the first inner wall 311 of the insert 300. At the same time, the fixing bolt 500 connects the fixing member 400 and the mounting member 200, making it impossible for insert 300 to come out of the first slide groove 110, thus achieving the effect of fixing insert 300. When insert 300 needs to be removed, the fixing member 400 is flipped over and the limiting block 410 abuts against the second inner wall 312 of insert 300. By applying external force to the fixing member 400, insert 300 can be forced to detach from mold 100, and then insert 300 can be removed from it. Since the insert 300 can be removed and installed from the side of the mold 100, and the fastener 400 is also inserted from the side of the mold 100, the removal and installation of the insert 300 is not affected even when the back of the mold 100 is covered by the injection molding machine, making the removal and installation more convenient and reducing the removal and installation process and labor burden.

[0056] Furthermore, one side of the second slide 120 extends to the back of the mold 100, so that the internal structure of the first slide 110 can be seen directly from the back of the mold 100. When the mold 100 is separated from the injection molding machine, the insert 300 can be directly installed from the back of the mold, and it is also convenient for subsequent cleaning and maintenance of the inside of the mold 100.

[0057] Furthermore, the mold structure with quick-release inserts also includes a base plate 600, which is installed on the back of the mold 100 to cover the open sides of the first slide 110 and the second slide 120 on the back of the mold 100. The base plate 600 is then directly connected to the injection molding machine. Moreover, the base plate 600 has a clearance groove 610 that engages with the second slide 120, providing a larger entry channel for the insert 300 when it enters from the side of the mold 100, thus facilitating the insertion of the insert 300.

[0058] Regarding the insertion method of insert 300 from the side of mold 100, the mold structure with quick-release insert also includes a screw. Insert 300 has a threaded countersunk hole 320, and the screw is threadedly connected to the threaded countersunk hole 320. Before insert 300 enters, one end of the screw is screwed into the threaded countersunk hole 320, and then the screw pushes insert 300 into the second slide groove 120. After insert 300 contacts mounting part 200, it indicates that insert 300 has reached the first slide groove 110. The screw then guides insert 300 to move along the first slide groove 110 until the end of insert 300 passes through through hole 111, at which point insert 300 is installed in place. Finally, loosen the screw and remove it. When insert 300 needs to be removed, the screw is also threadedly connected to the threaded countersunk hole 320 to bring insert 300 out of mold 100. In order to make full use of the existing structure, in some embodiments, the screw can also be replaced by the fixing bolt 500. The threaded countersunk hole 320 is designed to be the size that can be adapted to the fixing bolt 500. Thus, after the fixing bolt 500 completes the installation of the insert 300, it can also serve as a connector between the fixing part 400 and the mounting part 200, thus serving two purposes.

[0059] Furthermore, referring to Figure 3 ( Figure 3 a is a 3D view of the mounting component 200. Figure 3 (b is a cross-sectional view of the mounting component 200). The mounting component 200 has a fixing groove 210 for inserting the limiting block 410. The fixing groove 210 is adapted to the end shape of the limiting block 410, thereby guiding the limiting block 410 into place. The fixing groove 210 has a threaded hole, and the fixing component 400 has a fixing hole 420. The two ends of the fixing hole 420 extend to the end face of the fixing component 400 and the end face of the limiting block 410, respectively. The fixing bolt 500 is inserted into the fixing hole 420 and threadedly connected to the threaded hole in the fixing groove 210. Thus, the direction of the force applied by the fixing bolt 500 coincides with the axis of the limiting block 410, making the fixing more stable.

[0060] Furthermore, the mounting component 200 is also provided with a clearance hole 220. When the insert 300 is removed, the limiting block 410 of the fixing component 400 extends into the clearance hole 220, so that the fixing component 400 can extend a further distance along the third slide groove 130, thereby pushing the insert 300 out.

[0061] The insert assembly / disassembly method in the second aspect of the present invention is based on the above-mentioned mold structure with quick-release inserts, and includes an insert assembly method and an insert removal method.

[0062] The methods for installing the inserts include:

[0063] S110. (Refer to) Figure 6 Insert the mounting piece 200 into the first groove 110 and fix it to the mold 100, then fix the base plate 600 to the back of the mold 100;

[0064] S120. Reference Figure 7 Insert the insert 300 into the second slide groove 120, and then into the first slide groove 110 until it reaches the bottom, so that the end of the insert 300 protrudes from the through hole 111;

[0065] S130. Insert the fastener 400 into the third slide groove 130, refer to... Figure 8 The limiting block 410 at the end of the fixing member 400 abuts against the first inner wall 311 of the insert 300;

[0066] S140. After passing the fixing bolt 500 through the square hole 310 of the fixing part 400 and the insert 300 in sequence, connect it with the mounting part 200 to fix it, and complete the installation of the insert 300.

[0067] Methods for removing inlays include:

[0068] S210. Loosen the fixing bolt 500 and pull out the fixing bolt 500 and the fastener 400 from the third slide groove 130;

[0069] S220. Flip the retainer 400 and insert it again into the third slide 130, refer to Figure 9 The limiting block 410 at the end of the fixing member 400 abuts against the second inner wall 312 of the insert 300;

[0070] S230. Apply force to the end face of the fastener 400 to make it continue to penetrate deeper. This can be done by applying static pressure or by striking to force the insert 300 to disengage from the first groove 110.
