Description

Technical Field

[0001] This patent relates to the field of mold technology, specifically a multi-mode lens injection mold. Background Art

[0002] A multi-mode lens injection mold is a mold that has multiple mold cavities in the upper mold and the lower mold. To increase the cooling effect of the mold, multiple heat dissipation holes are set on the upper mold and the lower mold. The fan on one side blows cold air into the small holes to take away the heat from the upper mold and the lower mold. However, the cold air blown by the fan on one side of the upper mold and the lower mold will not completely enter the small holes, thereby reducing the heat dissipation and cooling efficiency of the mold. For this reason, we propose a multi-mode lens injection mold. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of this patent to clearly and completely describe the technical solutions in the embodiments of this patent. Obviously, the described embodiments are only part of the embodiments of this patent, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0020] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This patent provides a technical solution: a multi-mode lens injection mold, including a lower mold 1 and an upper mold 2, the top of the lower mold 1 and the bottom of the upper mold 2 are both provided with the same number of mold cavities, the top of the upper mold 2 is embedded with an injection tube 3, the right sides of the lower mold 1 and the upper mold 2 are both provided with small holes 4, the right sides of the lower mold 1 and the upper mold 2 are both fixedly installed with vertical magnetic strips 5 and horizontal magnetic strips 6, and the right sides of the lower mold 1 and the upper mold 2 are provided with a heat dissipation mechanism 7;

[0021] The heat dissipation mechanism 7 includes a fan 8, a plastic cover 9 is fixedly installed on the left side of the fan 8, a magnetic frame 10 is fixedly installed on the left end of the plastic cover 9, the vertical magnetic strip 5 and the horizontal magnetic strip 6 are combined into a square frame, and the left side of the magnetic frame 10 is adsorbed on the right side of the vertical magnetic strip 5 and the horizontal magnetic strip 6.

[0022] The magnetic frame 10 is also composed of two kinds of magnetic strips, horizontal and vertical, and can be adsorbed on the vertical magnetic strip 5 and the horizontal magnetic strip 6 through the magnetic frame 10, so that the plastic cover 9 and the small hole 4 are connected as a whole.

[0023] Specifically, an upper copper plate 11 is fixedly mounted on the top end of the inner wall of the small hole 4 , and a lower copper plate 12 is fixedly mounted on the bottom end of the inner wall of the small hole 4 .

[0024] The upper copper plate 11 and the lower copper plate 12 are both made of pure copper. Pure copper has excellent thermal conductivity, which can increase the contact area between the inner wall of the small hole 4 and the flowing air in the small hole 4, thereby improving the heat dissipation speed.

[0025] Specifically, the upper copper plate 11 and the lower copper plate 12 are inclined to the left.

[0026] The upper copper plate 11 and the lower copper plate 12 are tilted to the left to adapt to the flow direction of air.

[0027] Specifically, a support rod 13 is fixedly installed at the bottom of the outer wall of the fan 8, and mounting rings 14 are integrally formed at both the front and rear ends of the outer wall of the fan 8, and bolts 15 are provided inside the two mounting rings 14.

[0028] In the conventional technology, the bottom of the lower mold 1 is fixed on the workbench, the bottom end of the support rod 13 can be made on the workbench, and the bottom end of the bolt 15 is screwed into the screw hole on the workbench to fix the fan 8.

[0029] Specifically, the support rod 13 includes a vertical tube 16 and a vertical pole 21. The bottom end of the vertical pole 21 is inserted into the vertical tube 16. The right end of the side wall of the vertical pole 21 is provided with a tooth groove 22 which is continuously distributed up and down. The top side of the right end of the inner wall of the vertical tube 16 is provided with a square groove 17. The right wall of the square groove 17 is provided with a threaded hole. A screw 18 is threaded in the threaded hole. A pressure plate 19 is attached to the left end of the screw 18. The left side surface of the pressure plate 19 is tightly attached to the right end of the side wall of the vertical pole 21. The left side surface of the pressure plate 19 is integrally formed with a tooth 20, and the tooth 20 is inserted in the tooth groove 22.

[0030] When the height of the lower mold 1 and the upper mold 2 to be cooled is relatively large, the overall height of the vertical cylinder 16 and the vertical rod 21 can be increased to make the fan 8 adapt to the height change of the lower mold 1 and the upper mold 2. At this time, plastic covers 9 and magnetic frames 10 of different sizes can be installed on the left side of the fan 8.

[0031] Specifically, the pressing plate 19 is square in shape, and the side wall of the pressing plate 19 and the inner side wall of the square groove 17 are relatively fitted and slidable.

[0032] The side wall of the pressing plate 19 and the inner wall of the square groove 17 slide relative to each other to limit the moving track of the pressing plate 19 so that it can only move left and right.

[0033] Specifically, a spring 23 is sleeved on the side wall of the screw rod 18 , the left end of the spring 23 is fixedly mounted on the right side of the pressure plate 19 , and the right end of the spring 23 is fixedly mounted on the right wall of the square groove 17 .

[0034] Figure 5 The spring 23 is shown in a stretched state. When the screw rod 18 moves to the right, the spring 23 can rebound to drive the pressing plate 19 to move to the right, and the inserting tooth 20 automatically disengages from the tooth groove 22.

[0035] Working principle: The upper mold 2 is driven by the injection molding machine to move downward and snap onto the top of the lower mold 1. Liquid resin is injected into the mold cavities of the lower mold 1 and the upper mold 2 through the injection tube 3. After the injection is completed, it is adsorbed on the vertical magnetic strips 5 and the horizontal magnetic strips 6 through the magnetic frame 10, and then cold air is blown into the small holes 4 through the fan 8 to dissipate heat and cool the lower mold 1 and the upper mold 2.

[0036] It is worth noting that the small hole 4 is in an independent hole body and is not connected to the mold cavity in the lower mold 1 and the upper mold 2.
