Description

Technical Field

[0001] This utility model relates to the technical field of manufacturing equipment for lens barrel products, specifically to a lens barrel mold that facilitates product removal. Background Technology

[0002] An optical lens includes a lens barrel and a lens assembly installed inside the lens barrel. The lens assembly includes multiple lenses. Light enters from the object side of the lens barrel, passes through the lens assembly, and then enters the photosensitive chip through the image side of the lens barrel, thereby achieving image formation. Typically, the lens barrel is injection molded using a lens barrel molding die.

[0003] In the existing technology, after the lens barrel product is formed inside the mold, a robotic arm is needed to remove the product after the mold is opened. However, in actual use, it has been found that since the product injection is generally injected from the upper mold plate and the injection runner is also located on the upper mold plate, the product may still be connected to the upper mold plate during the mold opening process. This results in the need to remove the product from the upper mold plate later, which causes inconvenience to the continuous processing of the product and urgently needs to be improved. Utility Model Content

[0004] Based on the above description, this utility model provides a lens barrel mold that facilitates product removal, thereby solving the technical problem in the prior art where the product is attached to the upper template when the lens barrel mold is opened, which makes it inconvenient for the subsequent robotic arm to grasp the product.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A lens barrel mold for easy product removal includes a base, an upper mold, a lower mold, and a mold opening drive assembly;

[0007] The base includes a support plate, on which multiple hooks are vertically arranged;

[0008] The upper mold includes an upper template, which is disposed above the tray. The lower end face of the upper template has a material flow channel, and the hook rods are distributed corresponding to the material flow channel.

[0009] The lower mold includes a lower template, a lower mold support plate, a guide member, and a lifting block. The lower template and the lower mold support plate are stacked from top to bottom between the support plate and the upper template. The lifting block is disposed on the lower template, and at least a portion of the adhesive flow channel corresponds to the lifting block. The guide member is disposed on the lower mold support plate and extends upward through the lower template. The lifting block can slide up and down relative to the guide member.

[0010] The mold opening drive assembly includes a drive plate and an ejector rod. The drive plate is disposed below the support plate. The lower end of the ejector rod is connected to the drive plate, and the upper end moves through the support plate and connects to the lower mold plate.

[0011] The upper end of the hook rod passes through the lower mold support plate and the lower template and extends to the upper end face of the lifting block. The upper end of the hook rod has a hooking part. The stroke of the lower mold support plate relative to the support plate is less than the stroke of the lower template.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0013] The lens barrel mold provided in this application, due to the design of the hook rod, wraps the hook part during the molding process of the product moving in the rubber flow channel. When the upper and lower mold plates are separated, the hook rod restricts the product structure, so that when the upper mold plate is detached, the hook rod pulls the product out of the rubber flow channel of the upper mold plate. Then, the lifting block is driven to rise by the lifting rod, raising the product for easy clamping. Since the upward stroke of the lower mold support plate relative to the support plate is less than the stroke of the lower mold plate, the upper end of the hook rod can be completely detached from the product during the rising process of the lifting block, which is convenient for the subsequent robot to directly clamp. After adopting the technical solution of this application, the technical problem of the product being attached to the upper mold plate during mold opening, which leads to the difficulty of subsequent clamping, can be effectively solved.

[0014] Based on the above technical solution, the present invention can be further improved as follows.

[0015] Furthermore, the hook rod includes a rod seat and a rod body. The rod seat is connected to the lower end of the rod body. Both the rod seat and the rod body are cylindrical structures. The cross-section of the rod seat is larger than the cross-section of the rod body. The lower end face of the lower mold support plate has a first stepped hole corresponding to the rod seat.

[0016] Furthermore, the hook portion is a frustum-shaped structure formed at the upper end of the rod, and the diameter of the frustum-shaped structure gradually decreases from top to bottom.

[0017] Furthermore, the lower mold support plate is connected to the support plate by a limiting bolt. The limiting bolt includes a bolt body and a bolt head. The lower end of the bolt body is fixed to the support plate, and the bolt head is located at the upper end of the bolt body. The upper end face of the lower mold support plate has a second stepped hole corresponding to the limiting bolt. The bottom surface dimension of the bolt head is larger than the step surface dimension of the second stepped hole, and the distance from the bottom surface of the bolt head to the support plate is greater than the distance from the step surface of the second stepped hole to its bottom surface.

[0018] Furthermore, the difference between the distance from the bottom surface of the bolt head to the support plate and the distance from the step surface of the second stepped hole to its bottom surface is greater than the height dimension of the frustum-shaped structure.

[0019] Furthermore, the material flow channel includes four main channels, which radiate outward from a preset center point and are evenly distributed. The hook includes a central hook corresponding to the center point and a flow channel hook corresponding to each of the main channels.

[0020] Furthermore, the lower mold also includes a support plate, which is disposed between the lower template and the lower mold support plate, and the guide and the hook rod both pass through the support plate.

[0021] Furthermore, the base also includes a base plate and a mold foot, the mold foot being vertically fixed to the upper end of the base plate, the drive plate being disposed between the base plate and the support plate, and a shock-absorbing pad being connected to the lower end face of the drive plate.

[0022] Furthermore, the base also includes a guide post, which is vertically fixed to the upper end of the mold foot, and the lower template, support plate and lower mold support plate are all movably fitted onto the guide post. Attached Figure Description

[0032] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to the other element or connected to the other element through an intermediary element. In the following embodiments, "connection" should be understood as "electrical connection," "communication connection," etc., if the connected circuits, modules, units, etc., have the transmission of electrical signals or data between them.

[0033] When used here, the singular forms of “a,” “an,” and “ / the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “including / contains” or “having” specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0034] like Figures 1 to 6 As shown in the figure, this application embodiment provides a lens barrel mold that facilitates product removal, which includes a base 10, an upper mold 20, a lower mold 30, and a mold opening drive assembly 40.

[0035] The base 10 includes a base plate 11, mold feet 12, a support plate 13 and guide posts 14, and multiple hook rods 15 are vertically arranged on the support plate 13.

[0036] The upper mold 20 includes an upper template 21, which is positioned above the support plate 13. The lower end face of the upper template 21 has a material flow channel 210, and the hook rods 15 are distributed corresponding to the material flow channel 210.

[0037] The lower mold 30 includes a lower template 31, a lower mold support plate 32, a guide member 33, and a lifting block 34. The lower template 31 and the lower mold support plate 32 are stacked from top to bottom between the support plate 13 and the upper template 21. The lifting block 34 is disposed on the lower template 31, and the material flow channel 210 part corresponds to the lifting block 34. The guide member 33 is disposed on the lower mold support plate 32 and extends upward through the lower template 31. The lifting block 34 can slide up and down relative to the guide member 33.

[0038] The mold opening drive assembly 40 includes a drive plate 41 and an ejector rod 42. The drive plate 41 is disposed between the base plate 11 and the support plate 13. The lower end of the drive plate 41 is connected to a shock-absorbing pad. The lower end of the ejector rod 42 is connected to the drive plate 41, and the upper end moves through the support plate 13 and is connected to the lower template 31.

[0039] When the drive plate 41 drives the push rod 42 to rise, the push rod 42 will push the lower template 31 to rise, which in turn drives the lifting block 34 to rise, so that the product on the lifting block 34 is separated from the guide 33, forming a gap below, which is convenient for clamping.

[0040] The upper end of the hook rod 15 passes through the lower mold support plate 32 and the lower template 31 and extends to the upper end face of the lifting block 34. The upper end of the hook rod 15 forms a hooking part 1503. The stroke of the lower mold support plate 32 relative to the support plate 13 that can move upward is less than the stroke of the lower template 31.

[0041] In a preferred embodiment of this application, the material flow channel 210 includes four main channels 211. The four main channels 211 are radiating outward from a preset center point A and are evenly distributed. The injection molding material flows in from the inlet at the center point A and then flows within the four main channels 211. The ends of the main channels 211 have cavity structures for lens barrel molding. The four main channels 211 form a cross-shaped structure. The hook rod 15 includes a central hook rod 151 corresponding to the center point A and a flow channel hook rod 152 corresponding to each main channel.

[0042] The design of the five hooks 15 ensures that the product is evenly stressed when the hooks 15 pull the molded product out of the rubber flow channel 210, preventing excessive local stress and deformation.

[0043] Specifically, the hook rod 15 includes a rod seat 1501 and a rod body 1502. The rod seat 1501 is connected to the lower end of the rod body 1502. Both the rod seat 1501 and the rod body 1502 are cylindrical structures. The cross-section of the rod seat 1501 is larger than the cross-section of the rod body 1502. The lower end face of the lower mold support plate 32 has a first stepped hole 32a corresponding to the rod seat 1501.

[0044] The above structural design ensures that the up-and-down movement of the lower mold support plate 32 is guided by the hook rod 15, guaranteeing its accurate up-and-down movement.

[0045] In this embodiment, the hook part 1503 is a frustum-shaped structure formed on the upper end of the rod 1502, and the diameter of the frustum-shaped structure gradually decreases from top to bottom. The design of the frustum-shaped structure can ensure that it has a certain pulling force on the product, and at the same time, it can smoothly detach from the product during the subsequent mold opening and lifting process.

[0046] In this application, the movement stroke of the lower mold plate 32 is limited in the following way:

[0047] The lower mold support plate 32 is connected to the support plate 13 by a limiting bolt 321. The limiting bolt 321 includes a bolt body 3211 and a bolt head 3212. The lower end of the bolt body 3211 is fixed to the support plate, and the bolt head 3212 is located at the upper end of the bolt body 3211. The upper end face of the lower mold support plate 32 has a second stepped hole 32b corresponding to the limiting bolt 321. The bottom surface dimension of the bolt head 3212 is larger than the stepped surface dimension of the second stepped hole 32b. The distance from the bottom surface of the bolt head 3212 to the support plate 13 is greater than the distance from the stepped surface of the second stepped hole 32b to its bottom surface.

[0048] To ensure that the hook part 1503 is completely disengaged from the product, the difference between the distance from the bottom surface of the bolt head 3212 to the support plate 13 and the distance from the step surface of the second step hole 23b to its bottom surface is greater than the height dimension of the frustum-shaped structure.

[0049] To enhance the structural strength of the lower template 31, the lower mold 30 also includes a support plate 35, which is disposed between the lower template 31 and the lower mold support plate 32, and the guide member 33 and the hook rod 15 both pass through the support plate 35.

[0050] Correspondingly, in order to strengthen the structural strength of the upper template 21, the upper mold 20 also includes an upper support plate 22, which is fixed to the upper end of the upper template 21.

[0051] The lens barrel mold provided in this application, due to the design of the hook rod 15, wraps the hook part 1503 during the product's movement and forming process in the material flow channel 210. When the upper mold plate 11 and the lower mold plate 15 separate and open, the hook rod 15 restricts the product structure, so that when the upper mold plate 11 is detached, the hook rod 15 pulls the product out of the material flow channel 210 of the upper mold plate 21. Then, the lifting block 34 is raised by the lifting rod 42, raising the product height for easy clamping. Since the stroke of the lower mold support plate 32 relative to the support plate 13 is less than the stroke of the lower mold plate 31, the upper end of the hook rod 15 detaches from the product during the rising process of the lifting block 34, and the robot can directly clamp it afterward. After adopting the technical solution of this application, the technical problem of the product being attached to the upper mold plate 21 during mold opening, causing subsequent clamping difficulties, can be effectively solved.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
