Detailed Implementation

[0032] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0033] like Figure 1 As shown, in one embodiment of this utility model, a combined mold is provided. Figure 1 As shown, a combined mold according to one embodiment of the present invention includes a lower mold body 1 and an upper mold body 2. The upper mold body 2 covers the lower mold body 1, and a long screw 4 is threadedly connected to the lower mold body 1 and the upper mold body 2. Specifically, the lower mold body 1 and the upper mold body 2 are detachably covered together by the long screw 4. In use, the upper mold body 2 is covered on the lower mold body 1. After the workpiece is formed, the long screw 4 is turned to remove the upper mold body 2, and the formed workpiece can be taken out.

[0034] like Figures 2 to 4 As shown, a first placement groove 11 is provided on the lower mold body 1, and a lower mold core 12 is detachably connected in the first placement groove 11. Specifically, there are multiple lower mold cores 12, and each lower mold core 12 has a different molding cavity. Similarly, a third placement groove 21 is provided on the upper mold body 2, and an upper mold core 22 that matches the lower mold core 12 is detachably connected in the third placement groove 21.

[0035] To secure the lower mold core 12 within the first placement groove 11, a pair of first threaded cylinders 14 are welded to the upper plate of the first placement groove 11. The lower mold core 12 has a first through hole 1201 that matches the first threaded cylinders 14, and the first threaded cylinders 14 pass through the first through hole 1201. A fixing assembly is threaded onto the first threaded cylinders 14. The fixing assembly includes a sleeve 6, on which a bolt 61 is welded. The bolt 61 passes through the upper end face of the sleeve 6, and the nut of the bolt 61 is welded to the upper plate of the sleeve 6.

[0036] Specifically, the sleeve 6 is fitted onto the first threaded cylinder 14, and the bolt 61 on the sleeve 6 is threaded into the first threaded cylinder 14. When fixing the lower mold core 12, the sleeve 6 is aligned with the first threaded cylinder 14 and fitted onto the first threaded cylinder 14, and the nut of the bolt 61 is turned. The bolt 61 can then engage with the internal thread on the first threaded cylinder 14. The lower end face of the sleeve 6 abuts against the upper panel of the lower mold core 12, thereby fixing the lower mold core 12 in the first placement groove 11.

[0037] Similarly, a pair of second threaded cylinders 24 are welded to the upper plate of the upper mold core 22. The upper mold core 22 has a third through hole 2201 that matches the second threaded cylinders 24, and the second threaded cylinders 24 pass through the third through hole 2201. When the upper mold core 22 is fixed in the third placement groove 21, the sleeve 6 is fitted onto the second threaded cylinders 24, and the nut on the bolt 61 is turned. The bolt 61 engages with the internal thread of the second threaded cylinder 24, and the lower plate of the sleeve 6 abuts against the upper plate of the second threaded cylinder 24, thus fixing the upper mold core 22 in the third placement groove 21.

[0038] When it is necessary to replace the lower mold core 12 in the first placement slot 11, turn the sleeve 6 to unscrew the bolt 61 from the first threaded sleeve 14, and the lower mold core 12 can be removed for replacement. Similarly, the same operation can be performed when replacing the upper mold core 22.

[0039] Furthermore, a reinforcing ring 62 is integrally formed at the end of the sleeve 6 away from the bolt 61. The reinforcing ring 62 increases the contact area between the sleeve 6 and the upper surface of the lower mold core 12, increasing the pressure of the sleeve 6 on the lower mold core 12, making the lower mold core 12 more securely placed in the first placement groove 11. Similarly, the reinforcing ring 62 also increases the contact area with the upper surface of the upper mold core 22, making the upper mold core 22 more securely placed in the third placement groove 21.

[0040] It is worth noting that, due to the obstruction of the sleeve 6, the upper mold body 2 cannot be closed onto the lower mold body 1. To solve this problem, a second placement groove 13 matching the sleeve 6 is provided on the lower mold body 1, and a fourth placement groove 23 matching the sleeve 6 is provided on the upper mold body 2. Simultaneously, a second through hole 1202 matching the reinforcing ring 62 is provided on the lower mold core 12, and a fourth through hole 2202 matching the reinforcing ring 62 is provided on the upper mold core 22.

[0041] Specifically, when the upper mold body 2 is placed on the lower mold body 1, the sleeve 6 enters the second placement groove 13 and the fourth placement groove 23 respectively, and the reinforcing ring 62 on the sleeve 6 can also enter the second through hole 1202 and the fourth through hole 2202 respectively. In this way, the upper mold body 2 can be placed on the lower mold body 1, so that the lower mold core 12 and the upper mold core 22 are in contact. Then, the long rod screw 4 is tightened to start the production work.

[0042] It is worth noting that the first threaded cylinder 14 and the second threaded cylinder 24 are installed in a staggered manner. Specifically, as shown... Figure 2 , Figure 3 and Figure 6 As shown, the first threaded cylinder 14 is welded horizontally to the lower mold body 1, and the second threaded cylinder 24 is welded vertically to the upper mold body 2. This arrangement avoids affecting the connection between the upper mold body 2 and the lower mold body 1.

[0043] like Figure 1As shown, after the upper mold body 2 is closed on the lower mold body 1, the upper end face of the lower mold core 12 is attached to the upper end face of the upper mold core 22, and the heat dissipation opening 5 is naturally formed between the lower mold body 1 and the upper mold body 2, which is beneficial to the heat dissipation of the combined mold during the injection molding of the workpiece.

[0044] Further, in order to accelerate the molding speed of the workpiece in the first placing groove 11 and the upper mold core 22, as shown, Figures 3 to 6 As shown, the first cooling groove 1203 is formed on the lower mold core 12, and a pair of first hollow studs 3 are inserted into the groove wall of the first cooling groove 1203. The end of the first hollow stud 3 away from the lower mold core 12 penetrates through the side wall of the lower mold body 1. The first limiting block 31 is integrally formed on the first hollow stud 3, and the end face of the first limiting block 31 is attached to the side wall of the lower mold body 1. The first hollow stud 3 is threadedly connected with the first communication block 32 at the end away from the lower mold body 1, and the first water pipe 33 is inserted into the end of the first communication block 32 away from the first hollow stud 3.

[0045] Specifically, the cooling liquid flows through the first water pipe 33 on the right side of the lower mold body 1, flows into the first cooling groove 1203 through the first hollow stud 3, and then flows out from the first hollow stud 3 on the left side, which can dissipate heat for the lower mold core 12 and make the workpiece in the molding cavity of the lower mold core 12 be molded more quickly.

[0046] Further, the first limiting block 31 is integrally formed with the first handle 311. When replacing the lower mold core 12 in the first placing groove 11, the first handle 311 is held and rotated, so that the first hollow stud 3 is withdrawn from the first cooling groove 1203, and the lower mold core 12 can be taken out. It is worth noting that when cooling the lower mold core 12, in order to ensure that the first hollow stud 3 can enter the first cooling groove 1203, the first handle 311 is rotated, and when the side wall of the first limiting block 31 is attached to the side wall of the lower mold body 1, the first hollow stud 3 is inserted into the first cooling groove 1203. In this way, the first hollow stud 3 cannot be seen, but the cooling liquid in the first hollow stud 3 can enter the first cooling groove 1203. At the same time, when the first hollow stud 3 is rotated, because of the first communication block 32, the first water pipe 33 does not rotate, and the flowability of the cooling liquid in the first water pipe 33 is maintained.

[0047] Similarly, the second cooling groove 2203 is formed on the upper mold core 22, and the second hollow stud 7 is inserted into the groove wall of the second cooling groove 2203. The end of the second hollow stud 7 away from the upper mold core 22 penetrates through the side wall of the upper mold body 2. The second limiting block 71 is integrally formed on the second hollow stud 7, and the end face of the second limiting block 71 is attached to the side wall of the upper mold body 2. The second hollow stud 7 is threadedly connected with the second communication block 72 at the end away from the upper mold body 2, and the second water pipe 73 is inserted into the end of the second communication block 72 away from the second hollow stud 7. The second limiting block 71 is integrally formed with the second handle 711.

[0048] When the lower mold core 12 and the upper mold core 22 need to be replaced, the sleeve 6 is screwed, the sleeve 6 is removed, and the lower mold core 12 and the upper mold core 22 can be replaced. After replacement, the sleeve 6 is aligned with the first threaded cylinder 14 on the lower mold body 1, the sleeve 6 is screwed, the bolt 61 on the sleeve 6 is screwed into the first threaded cylinder 14, and the lower surface of the sleeve 6 abuts against the upper surface of the lower mold core 12, so that the lower mold core 12 is fixed in the first placing groove 11.

[0049] Similarly, after the sleeve 6 is screwed into the second threaded cylinder 24 on the upper mold body 2, and the lower surface of the sleeve 6 abuts against the upper surface of the upper mold core 22, the upper mold core 22 is also fixed in the third placing groove 21. In this way, different lower mold cores 12 and upper mold cores 22 can be replaced according to the workpieces to be produced.
