[0002] Hot runner molds are molds that use a heating device to prevent the melt in the runner from solidifying. Because they have a shorter molding cycle than traditional molds and are more material-efficient, hot runner molds are widely used in industrially developed countries and regions around the world.

[0003] After searching, the patent with announcement number CN218876146U discloses a hot runner mold, which records that "it includes an upper cover plate and a side plate, the lower end of the upper cover plate is provided with an outer plate, and the lower end of the outer plate is provided with assembly block one, the lower end of the assembly block one is provided with assembly block two, and the lower end of the assembly block two is provided with assembly block three, the side plate is provided at the lower end of assembly block three, and a blanking assembly passes through the middle of the upper end of the upper cover plate. Compared with existing ordinary hot runner molds, the hot runner mold is used by operators to unscrew the screws on the upper cover plate to complete the assembly of the outer frame, so that the outer frame can be quickly assembled. When maintenance is required, the screws on the upper cover plate can also be removed to quickly disassemble the outer frame, thereby facilitating the maintenance and installation of the equipment..." From the above, it can be seen that the hot runner mold of this patent is not easy to remove bubbles when adding liquid raw materials. The bubbles generated will affect the quality of the product, and there are certain shortcomings. Utility Model Content

[0025] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0026] The following describes some embodiments of the present invention in conjunction with the accompanying drawings to provide a hot runner anti-bubble molding mold.

[0027] Example 1:

[0028] Reference Figure 1-6 , which is the first embodiment of the present utility model, provides a hot runner anti-bubble molding mold, including a support assembly 100, a lower mold base assembly 200, a lower sealing assembly 300, a fastening assembly 400, an upper mold base assembly 500 and an upper sealing assembly 600.

[0029] Specifically, the support assembly 100 includes a support plate 101, a support rod 103 arranged on the top of the support plate 101 and a fixed shaft 104 arranged on the inner side of the support plate 101. The fixed shaft 104 allows the lower mold base body 201 to rotate on the support plate 101 so that the lower mold base body 201 can be shaken to remove bubbles.

[0030] Furthermore, a first sealing ring 102 is clamped on the top of the support plate 101 . The first sealing ring 102 can improve the sealing performance of the top cover 603 and prevent air from passing through the gap between the top cover 603 and the support plate 101 .

[0031] Specifically, the lower mold base assembly 200 includes a lower mold base body 201 rotatably connected to the fixed shaft 104 and an electric telescopic rod 202 rotatably connected to the bottom of the lower mold base body 201. Two electric telescopic rods 202 are provided, and the tops of the two electric telescopic rods 202 are rotatably connected to the lower mold base body 201. The bottoms of the two electric telescopic rods 202 are rotatably connected to the sealing box 301. The electric telescopic rods 202 can be controlled to extend and retract. The extension and retraction of the electric telescopic rods 202 can drive the lower mold base body 201 to move back and forth upward or downward, so that bubbles can be cleaned by shaking.

[0032] Specifically, the lower sealing assembly 300 includes a sealing box 301 arranged at the bottom of the support plate 101 and a sealing plate 303 hingedly connected to the sealing box 301. The sealing plate 303 can be rotated to cover the sealing box 301 to form a certain sealed space for vacuum treatment of bubbles.

[0033] Furthermore, a second sealing ring 302 is bonded to the front end of the sealing box 301 . The second sealing ring 302 can improve the sealing performance of the sealing plate 303 and prevent air from passing through the gap between the sealing plate 303 and the sealing box 301 .

[0034] Specifically, the fastening assembly 400 includes a cylinder 401 arranged at the front end of the sealing box 301, a baffle 402 rotatably connected to the cylinder 401, and a fastening knob 403 threadedly connected to the cylinder 401. The baffle 402 can be rotated until the baffle 402 blocks the sealing plate 303. After blocking, the fastening knob 403 is rotated to fix it so as to fix the sealing plate 303.

[0035] Specifically, the upper die base assembly 500 is arranged on the support rod 103. The upper die base assembly 500 includes a hydraulic cylinder 501 arranged on the support rod 103 and an upper die base body 502 arranged at the bottom of the hydraulic cylinder 501. The hydraulic cylinder 501 can drive the upper die base body 502 to move up and down for use.

[0036] Specifically, the upper sealing assembly 600 includes an electric push rod 601 arranged at the bottom of the support plate 101, a fixed plate 602 arranged at the top of the electric push rod 601, a top cover 603 arranged on the fixed plate 602, and a hose 604 arranged on the rear side of the top cover 603. The electric push rod 601 can be controlled to retract, and the retracted electric push rod 601 drives the top cover 603 to cover the top of the support plate 101, thereby forming a certain sealed space for vacuum treatment of bubbles. The hose 604 is fixedly connected to the vacuum pump, and the vacuum pump is used to extract the air in the lower sealing assembly 300 and the upper sealing assembly 600 through the hose 604, thereby forming a certain vacuum, thereby removing bubbles in the liquid raw material.

[0037] The working principle and use process of the present invention are as follows: when in use, the lower die base body 201 can be rotated on the support plate 101 through the fixed shaft 104, and then the electric telescopic rod 202 can be controlled to extend and retract. The extension and retraction of the electric telescopic rod 202 can drive the lower die base body 201 to do reciprocating motion upward or downward, and the bubbles can be cleaned by shaking. Then the sealing plate 303 can be rotated to cover the sealing box 301, and the baffle 402 of the fastening assembly 400 can be rotated until the baffle 402 blocks the sealing plate 303. After blocking, the fastening knob 403 is rotated to fix it, so that the sealing plate 303 can be fixed. After fixing, the electric push rod 601 can be controlled to retract. The retracted electric push rod 60 1 drives the top cover 603 to cover the top of the support plate 101, and a certain sealed space can be formed through the lower sealing assembly 300 and the upper sealing assembly 600. Then, a vacuum pump is used to extract the air in the sealing box 301 and the top cover 603 through the hose 604 to form a certain vacuum, so as to remove bubbles in the liquid raw material and prevent the bubbles from affecting the quality of the finished product. During the sealing process, the first sealing ring 102 can improve the sealing performance of the top cover 603 and prevent air from passing through the gap between the top cover 603 and the support plate 101, while the second sealing ring 302 can improve the sealing performance of the sealing plate 303 and prevent air from passing through the gap between the sealing plate 303 and the sealing box 301.

[0038] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
