Description

Technical Field

[0001] The utility model relates to the technical field of lens production equipment, in particular to a white material injection molding device for lens production. Background Art

[0002] In the field of cameras, plastics can be divided into two categories, commonly known as white materials and black materials. White materials are mainly used for various optical lenses, and black materials refer to various lens accessory materials other than lenses, such as plastic pressure rings, plastic lens barrels, bases, brackets, etc. White materials are mainly materials with good light transmittance, generally PC materials are used. During production, lenses are processed and formed by injection molding machines. Injection molding machines are also known as injection molding machines or injection machines. They can use plastic molding molds to make lenses of various shapes from white materials used for lens production. The following problems exist in the existing technology:

[0003] Chinese patent document CN114516140B discloses a white material injection molding device for lens production, which belongs to the field of injection molding. When in use, this solution introduces the raw material into the injection molding barrel through a feed hopper, and then melts it by heating the melting component, and stirs and conveys the raw material through an efficient energy-saving rod, and absorbs the melting component while conveying, and after the absorption reaches the same temperature as the injection molding barrel, a high-temperature layer is formed with the melting component, thereby making the raw material melting more efficient and effectively saving energy, thereby achieving energy saving while achieving rapid molding, and after the raw material passes through a bubble elimination mechanism, the water content in the raw material is reduced by the bubble elimination mechanism, so that the raw material is relatively dry after entering the injection molding barrel, thereby accelerating the melting efficiency of the raw material in the injection molding barrel, further improving the molding effect, and making the product yield after processing and molding higher, reducing additional economic losses.

[0004] Although the bubble elimination mechanism can be used to absorb moisture from the white material before processing in the above-mentioned document, the multiple evenly distributed diversion channels opened on the upper end of the sponge block included in the bubble elimination mechanism have small apertures, and the white material can only rely on its own gravity to pass through the diversion channels for feeding, resulting in a slow feeding speed, which affects the lens production efficiency. At the same time, after the sponge block and water absorption lines and other water absorption structures absorb the moisture of the material, they themselves will become wet, and the entire sponge block is still located in the inner cavity of the connecting block. Therefore, it is not convenient to know the water absorption of the sponge block, nor is it convenient to replace it in time, which leads to a reduction in the water absorption effect of the sponge block and the water absorption line on the white material, which still affects the yield rate of lens processing.

[0022] After drying, the white material particles entering the discharge hole 26 will fall into the inner cavity of the injection barrel 22 inserted into the inner cavity of the feed box 21. Finally, by starting the drive motor 24 to drive the injection screw 25 to rotate, the dried white material particles can be transported forward. After being heated and melted by the three melting components 23, injection molding can be carried out.

[0023] like Figure 3 , Figure 4As shown, a drying box 34 is fixedly installed on the front side of the unloading funnel box 3, two exhaust fans 341 are fixedly installed on the bottom of the inner wall of the drying box 34, heating resistor rods 342 are fixedly connected to the front ends of the left and right sides of the inner wall of the drying box 34, and a dustproof net 343 is fixedly installed on the rear side of the inner circle of the drying box 34.

When the sponge sleeve 48 needs to be replaced, remove the five-corner bolts on the left and right sides of the mounting box 45, and pull the entire mounting box 45, the two motors 46 and the two sponge sleeves 48 to the rear side, so that they are separated from the water absorption fixing ring 41 after passing through the insertion hole 43. During installation, align the two sponge sleeves 48 with the two insertion holes 43 and insert them until the mounting box 45 is stuck on the outer wall of the mounting frame 44, and then align the five-corner bolts with the holes on the left and right sides of the mounting box 45 and the left and right sides of the mounting frame 44, insert them and tighten them to fix them.

[0025] like Figure 5As shown, the discharge mechanism 5 includes a feeding annular cylinder 51, the top of the inner cavity of the feeding annular cylinder 51 is connected to the bottom of the inner cavity of the water absorption fixed ring 41 through a fixed connection, the bottom of the inner cavity of the feeding annular cylinder 51 is connected to the feeding box 21 opened at the top of the feeding box 21 through a fixed connection, a connecting rod 52 is fixedly installed on the front side of the inner ring of the feeding annular cylinder 51, a direction-changing driving box 53 is fixedly installed at the rear end of the connecting rod 52, and a guide triangular top 54 is fixedly installed on the top of the direction-changing driving box 53.

[0026] After double drying, the white material particles can enter the inner cavity of the unloading annular cylinder 51, and are prevented from accumulating on the top of the reversing drive box 53 by using the guide triangular top 54. Then, by starting the unloading motor 55, the bevel gear 1 56 in the inner cavity of the reversing drive box 53 can be driven to rotate. The bevel gear 1 56 is engaged with the bevel gear 2 57 to rotate the unloading spiral rod 58, and the white material particles entering the inner cavity of the unloading annular cylinder 51 are quickly discharged into the unloading hole 26 to prevent blockage.

[0027] The working principle of the white material injection molding device for lens production is described in detail below.

[0028] like Figure 1-5As shown, the white material particles used for lens production are uniformly injected into the inner cavity of the discharge funnel box 3 from the white material injection port 32. During the falling process, the heating resistor rod 342 in the inner cavity of the drying box 34 is started to generate heat, and the heated hot air is blown to the falling white material particles through two exhaust fans 341, thereby performing preliminary drying. The blown gas will be discharged through the air outlet 33, and the drawn gas will be filtered through the dustproof net 343 to prevent dust from being blown in. The preliminarily dried white material particles can pass through the guide funnel 42 and enter between the two sponge sleeves 48. The two motors 46 in the inner cavity of the mounting box 45 can drive the output shafts of the two motors 46 to rotate in opposite directions, thereby quickly clamping the white material particles and then discharging them downward, further absorbing the moisture in the particles. When the sponge sleeve 48 needs to be replaced, the five-angle bolts on the left and right sides of the mounting box 45 are removed, and the entire mounting box 45, the two motors 46 and the two sponge sleeves 48 are pulled out to the rear side, thereby inserting After the hole 43 is opened, the water-absorbing fixing ring 41 is separated. During installation, the two sponge sleeves 48 are aligned with the two insertion holes 43 and inserted until the installation box 45 is stuck on the outer wall of the installation frame 44.

The white material particles after double drying can enter the inner cavity of the blanking annular cylinder 51, and the guide triangular top 54 is used to prevent accumulation on the top of the reversing drive box 53. Then, by starting the blanking motor 55, the bevel gear 1 56 of the inner cavity of the reversing drive box 53 can be driven to rotate. The bevel gear 1 56 cooperates with the meshing of the bevel gear 2 57 to make the blanking screw rod 58 rotate, and the white material particles entering the inner cavity of the blanking annular cylinder 51 are quickly discharged into the blanking hole 26 and fall into the inner cavity of the injection molding barrel 22 inserted into the inner cavity of the feed box 21. Finally, by starting the drive motor 24 to drive the injection molding screw 25 to rotate, the dried white material particles can be transported forward. After being heated and melted by the three melting components 23, injection molding can be carried out.

[0029] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
