Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of injection molding, in particular to a mold for an injection molding part of a copier shell. BACKGROUND

[0002] The injection mold is a tool for producing plastic products, and also a tool for giving plastic products complete structure and precise size. Injection molding is a processing method used in batch production of some complex-shaped parts. Specifically, the molten plastic is injected into the mold cavity by the injection molding machine under high pressure, and the shaped product is obtained after cooling and solidification. The paper outlet of the copier shell and the top cover have different shapes and multiple chambers. After injection molding, the copier shell needs to be ejected, but due to the multiple chambers of the copier shell and the different depths of the chambers, the copier shell cannot be completely ejected at one time during the ejection process. Therefore, the mold for the injection molding part of the copier shell is proposed to solve the above problems. SUMMARY

[0003] In view of the deficiencies of the prior art, the present application provides a mold for an injection molding part of a copier shell, which solves the problems raised in the background art.

[0004] To achieve the above purpose, the present application realizes the following technical scheme: a mold for an injection molding part of a copier shell, comprising a mounting base, a movable hole is formed in the left surface of the mounting base, a driving ejector rod is movably installed in the movable hole formed in the left surface of the mounting base, a driving main plate is fixedly installed at the right end of the driving ejector rod, a threaded hole is formed in the right surface of the driving main plate, a ejector pin is threadedly connected in the threaded hole formed in the right surface of the driving main plate, a second shaft is fixedly installed in the inside of the driving main plate, a secondary driving plate is movably installed on the outer surface of the second shaft, a movable hole is formed in the upper side of the right surface of the mounting base, a second ejector pin is movably installed in the movable hole formed in the upper side of the right surface of the mounting base, a threaded groove is formed in the left end of the second ejector pin, and a limiting block is threadedly connected in the threaded groove formed in the left end of the second ejector pin.

[0005] Optionally, a limiting spring is arranged on the outer surface of the second ejector pin, and the limiting spring is between the mounting base and the limiting block.

[0006] Optionally, a sliding block is fixedly installed at the left and right ends of the driving main plate, the shape of the sliding block is a T-shaped protrusion, and a T-shaped sliding groove is formed in the inside of the left and right ends of the mounting base and matched with the sliding block.

[0007] Optionally, an installation groove is provided on the inner side of the sliding groove inside the mounting base. A first rotating shaft is fixedly installed in the installation groove. A rotating groove is provided on the outer surface of the first rotating shaft. A rotating sleeve is movably installed in the rotating groove on the outer surface of the first rotating shaft. The rotating sleeve is in movable contact with the active push rod.

[0008] Optionally, the diameter of the limiting block is larger than the diameter of the second ejector pin, and the limiting block is located on the right side of the secondary drive plate.

[0009] Optionally, a passive push rod is provided on the right side of the mounting base, and through holes are provided on the right surfaces of both the mounting base and the drive motherboard, with the through holes on the right surfaces of the mounting base and the drive motherboard being adapted to the passive push rod.

[0010] This invention provides a mold for injection molding a copier housing, which has the following beneficial effects:

[0011] 1. The mold for the injection molding of the copier housing uses an active ejector rod to drive the main board, causing the ejector pin to initially eject. When the passive ejector rod contacts the secondary drive plate, the bottom of the secondary drive plate rotates to the left, and the top of the secondary drive plate rotates to the right, thereby driving the limit block and causing the second ejector pin to eject a second time. This allows for one-time ejection of the copier housing with a punching chamber, improving material feeding efficiency.

[0012] 2. When the mold of the injection molded part of the copier housing drives the limiting block through the secondary drive plate, the limiting block will squeeze the limiting spring, causing the limiting spring to compress and deform. The elastic force generated when the limiting spring recovers its elastic deformation can reset the limiting block, thereby using the limiting block to reset the secondary drive plate, so that the secondary drive plate can complete the purpose of autonomous reset, which greatly improves the convenience of the device.

Obviously, the described embodiments are only some of the embodiments of the present application, not all.

[0020] Please refer to Figure 1 , Figure 3 and Figure 4 , the present application provides technical solutions: the mold of the injection molding part of the copier shell, including installation base body 1, the left surface of installation base body 1 is provided with a movable hole, the movable hole in the left surface of installation base body 1 is movably installed with active top rod 2, the right end of active top rod 2 is fixedly installed with drive main plate 3, the right surface of drive main plate 3 is provided with a threaded hole, the threaded hole in the right surface of drive main plate 3 is threadedly connected with thimble 7, the outer end of thimble 7 and limit block 11 are both provided with external threads, which can facilitate the installation of thimble 7 on the right surface of drive main plate 3, and the installation of limit block 11 in the second thimble 10, which can facilitate disassembly and improve disassembly efficiency, and facilitate users to overhaul and replace, the inside of drive main plate 3 is fixedly installed with second rotating shaft 8, the outside surface of second rotating shaft 8 is movably installed with secondary drive plate 9, the upper side of the right surface of installation base body 1 is provided with a movable hole, the movable hole in the upper side of the right surface of installation base body 1 is movably installed with second thimble 10, the left end of second thimble 10 is provided with a threaded groove, the threaded groove in the left end of second thimble 10 is threadedly connected with limit block 11, the diameter of limit block 11 is greater than the diameter of second thimble 10, limit block 11 is on the right side of secondary drive plate 9, limit block 11 can be driven by secondary drive plate 9, second thimble 10 can be limited by limit block 11, which avoids second thimble 10 from separating from the inside of drive main plate 3, and improves the integrity of the device.

[0021] Please refer to Figure 4 and Figure 5 , the outside surface of second thimble 10 is provided with limit spring 12, limit spring 12 is between installation base body 1 and limit block 11, the extrusion of limit spring 12 by limit block 11 can cause limit spring 12 to compress and deform, the elastic force generated when limit spring 12 restores elastic deformation can reset limit block 11, so that limit block 11 plays a resetting role on secondary drive plate 9.

[0022] Please refer to Figure 2 and Figure 3The left and right ends of the driving main plate 3 are fixedly provided with sliding blocks 4, the sliding blocks 4 are T-shaped protrusions, T-shaped sliding grooves are formed in the left and right ends of the mounting base 1 and are matched with the sliding blocks 4, the sliding blocks 4 can limit the stroke of the driving main plate 3, and the contact area between the sliding blocks 4 and the mounting base 1 can be increased, so that the connection between the driving main plate 3 and the mounting base 1 is more compact, and the driving main plate 3 is more stable during driving.

[0023] Please refer to Figure 2 and Figure 3 A mounting groove is formed in the inner side of the sliding groove of the mounting base 1, a first rotating shaft 5 is fixedly arranged in the mounting groove, a rotating groove is formed in the outer surface of the first rotating shaft 5, and a rotating sleeve 6 is movably arranged in the rotating groove of the first rotating shaft 5. The sliding friction between the sliding block 4 and the mounting base 1 is changed into rolling friction by the rotating sleeve 6, so that the friction between the mounting base 1 and the sliding block 4 is reduced, the loss between the mounting base 1 and the sliding block 4 is reduced, the service life of the mounting base 1 and the sliding block 4 is prolonged, and the rotating sleeve 6 movably contacts the driving top rod 2.

[0024] Please refer to Figure 1 and Figure 3 A passive top rod 13 is arranged on the right side of the mounting base 1, and a through hole is formed in the right surface of the mounting base 1 and the driving main plate 3. The through hole formed in the right surface of the mounting base 1 and the driving main plate 3 is matched with the passive top rod 13. The passive top rod 13 can drive the lower side of the secondary driving plate 9, so that the lower side of the secondary driving plate 9 is flipped to the left side, so that the upper side of the secondary driving plate 9 is flipped to the right side, and the prerequisite for driving the second top pin 10 is realized.

[0025] In summary, the mold of the injection molding part of the copier shell is used. First, the user needs to drive the driving top rod 2, so that the driving top rod 2 drives the driving main plate 3, so that the top pin 7 is preliminarily ejected. When the passive top rod 13 contacts the secondary driving plate 9, the bottom of the secondary driving plate 9 will rotate to the left side, and the top of the secondary driving plate 9 will rotate to the right side, so as to drive the limiting block 11, so that the second top pin 10 is ejected twice. When the ejection is completed, the driving top rod 2 is reset. Because the limiting block 11 extrudes the limiting spring 12, the limiting spring 12 is compressed and deformed. The elastic force generated when the limiting spring 12 restores the elastic deformation can reset the limiting block 11, so that the limiting block 11 resets the secondary driving plate 9. Thus, the secondary driving plate 9 is reset.
