Description

Technical Field

[0001] This utility model relates to the field of injection molding product processing technology, and in particular to a tooling for quickly removing small injection molded products that cannot be clamped. Background Technology

[0002] Injection molded products refer to various products manufactured by injection molding machines, including various packaging, parts, and plastic products. They are mainly made of materials such as polyethylene or polypropylene with the addition of various organic solvents. The choice of plastic parts depends on the type of plastic (thermoplastic or thermosetting), the initial form, and the shape and size of the product. Injection molded products are generally made using compression molding, transfer molding, and injection molding.

[0003] In the injection molding process, many products are small in size, light in weight, and have a lot of static electricity on their surface. The molds are also tightly arranged, making it difficult to achieve the desired results using ordinary suction and clamping methods.

[0004] Patent document CN221339301U discloses a clamping mechanism and a clamping assembly, including a fixed plate, a product storage mechanism, a clamping mechanism, and a positioning post mounted on the fixed plate. The positioning post is used to align with the positioning hole on the mold for manufacturing injection molded products, so that the mold aligns with the product storage mechanism, thereby storing the injection molded product made in the mold into the product storage mechanism. The clamping mechanism is used to clamp the product storage mechanism to hold the injection molded product stored in the product storage mechanism in the clamping assembly. This utility model is designed for clamping and collecting injection molded products that are small in size and lightweight. It has a simple structure, good product adaptability, and saves time and manpower.

[0005] The above solutions have a relatively complex clamping mechanism structure, involve many operations, and have a narrow range of applications. They still require manual collection of injection molded products and cannot quickly remove and collect small injection molded products that cannot be clamped. If small injection molded products are not collected in time, not only will raw materials be wasted, but the production space will also be polluted and messy. Therefore, it is necessary to provide a tooling for quickly removing small injection molded products that cannot be clamped to solve the shortcomings of the existing technology. Utility Model Content

The small injection-molded products are collected by the housing, and the bottom plate is opened and closed by the extension and retraction of the drive cylinder to remove the small injection-molded products.

[0009] The present invention is further configured such that the opening and closing component includes:

[0010] A fixing block, the top of which is connected to the end of the piston rod of the drive cylinder, and a through hole is provided at the bottom of the fixing block;

[0011] The pressing block has a top that connects to the bottom of the fixing block. The top of the pressing block has a through hole two, and the bottom of the pressing block has a sliding groove one.

[0012] A fixing pin, which passes through through hole one and through hole two in sequence to connect the pressing block and the fixing block;

[0013] A fixed base, one end of which is connected to the top surface of the base plate via a fixed plate, and the other end of which is provided with a sliding groove.

[0014] The movable pin passes through sliding groove one and sliding groove two in sequence to connect the fixed seat and the pressing block.

[0015] The present invention is further configured such that the diameter of the fixing pin is consistent with the diameter of the through hole one and the through hole two.

[0016] The present invention is further configured such that the first sliding groove and the second sliding groove are semicircular to rectangular, and the diameter of the movable pin is the same as the diameter of the semicircles at both ends of the semicircular to rectangular.

[0017] The present invention is further configured such that the main board and the back plate are respectively connected to two side plates and the top plate, and the middle parts of the two side plates are respectively hinged to a bottom plate.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0031] Example 1:

[0032] In this embodiment, as Figure 1-5As shown, this utility model proposes a quick-release fixture for small injection-molded products that cannot be gripped. It includes a housing 1, which is surrounded by a top plate 11, two side plates 12, two bottom plates 13, a main plate 14, and a back plate 15 to form a storage space. A bracket 2 is provided on the front of the main plate, and a drive cylinder 3 is mounted on the bracket. The piston rod 31 of the drive cylinder passes through the bracket and is vertically downwards. The end of the piston rod is connected to the top of an opening / closing assembly 4, and the bottom of the opening / closing assembly is connected to the top surface of the bottom plate. The back of the housing connects to the mold. The housing collects the small injection-molded products, and the bottom plate is opened and closed by the extension and retraction of the drive cylinder to remove the products. The removal speed is fast, avoiding the need to remove small injection-molded products from the opening slot. The housing can quickly perform secondary collection, reducing removal time and improving work efficiency.

[0033] In this example, small injection-molded products that cannot be clamped are collected in a unified box, which prevents them from scattering and causing pollution that renders them unusable and wastes raw materials. This also avoids manual collection, improves work efficiency, and reduces manual labor.

[0034] In this embodiment, the opening and closing assembly includes a fixed block 41, a pressing block 42, a fixing pin 43, a fixed seat 44, and a movable pin 45. The top of the fixed block is connected to the end of the piston rod of the driving cylinder, and the bottom of the fixed block has a through hole 1. The top of the pressing block is connected to the bottom of the fixed block, the top of the pressing block has a through hole 2, and the bottom of the pressing block has a sliding groove 1. The fixing pin passes through the through hole 1 and the through hole 2 in sequence to connect the pressing block and the fixed block. One end of the fixed seat is connected to the top surface of the base plate through a fixing plate 46, and the other end of the fixed seat has a sliding groove 2. The movable pin passes through the sliding groove 1 and the sliding groove 2 in sequence to connect the fixed seat and the pressing block.

[0035] In this example, the top of the opening and closing assembly is connected to the piston rod of the drive cylinder, and its position is fixed, so that the base plate is set horizontally in the initial state, and the base plate and the side plate are at a 90-degree angle.

[0036] In this embodiment, the diameter of the fixing pin is consistent with the diameter of the through hole one and the through hole two. The fixing pin can lock the pressing block and the fixing block to prevent the pressing block and the fixing block from sliding.

[0037] In this embodiment, the sliding groove one and sliding groove two are further configured to be semi-circular and rectangular in shape, and the diameter of the movable pin is the same as the diameter of the semi-circles at both ends of the semi-circular rectangle. The movable pin enables the fixed seat and the pressing block to have only relative displacement, thereby preventing the bottom plate from sagging under the action of gravity and preventing the box from losing its storage space.

[0038] In this embodiment, the motherboard and the back plate are further configured to be connected to two side plates and a top plate, respectively, and the middle parts of the two side plates are respectively hinged to a bottom plate via hinges 5.

[0039] In this embodiment, it is further configured such that one end of the two base plates is flush with the back plate, and the other end of the two base plates extends outward from the main board.

[0040] In this embodiment, the back plate is further configured to have an opening groove 151 in the middle, which corresponds to the mold output end.

[0041] The working principle of this tooling for quickly removing small injection molded products that cannot be gripped is as follows: The robotic arm is connected to the main board or side plate and moves the box to the mold so that the opening slot corresponds to the mold output end. The small injection molded products are output into the box through ejector pins or air pipes. After a certain amount is accumulated, the robotic arm moves the box above the discharge unit and drives the cylinder to control the extension rod to extend, so that the bottom plate opens at a certain angle. The small injection molded products in the box slide down the inclined bottom plate and are removed.

[0042] Example 2:

[0043] In this embodiment, as Figure 1-5 As shown, the difference from Embodiment 1 is that the opening and closing assembly includes a fixing block, a pressing block, and a fixing pin. The top of the fixing block is connected to the end of the piston rod of the driving cylinder, and the bottom of the fixing block is provided with a through hole one. The top of the pressing block is connected to the bottom of the fixing block, and the top of the pressing block is provided with a through hole two. The bottom of the pressing block abuts against the base plate. The fixing pin passes through the through hole one and the through hole two in sequence to connect the pressing block and the fixing block.

[0044] In this embodiment, a spring 6 is further provided in the middle of the hinge. The spring has a torque, which enables the bottom plate to abut against the bottom of the pressing block. At this time, the bottom plate and the side plate are at a 90-degree angle.

[0045] In this example, when the drive cylinder is not running, the bottom plate and the side plate are at a 90-degree angle, and the bottom plate abuts against the bottom of the pressing block. When the drive cylinder runs, the opening and closing assembly descends as the extension rod of the drive cylinder extends, thereby pressing the bottom plate open, so that the bottom plate and the side plate form an obtuse angle. The small injection molded products inside the box slide down the inclined bottom plate and are taken out. It is worth noting that the small injection molded products are relatively light, and the bottom plate cannot be opened under the action of gravity when the products are loaded at once.

[0046] In the description of this utility model, it should be noted that when terms such as "upper," "lower," "inner," "outer," "left," and "right" appear to indicate orientation or positional relationships, they should be understood as being based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationships commonly used when the product of this utility model is in use, or the orientation or positional relationships commonly understood by those skilled in the art. These terms are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, when terms such as "first" and "second" appear, they are only used to distinguish descriptions and should not be construed as indicating or implying relative importance. In the description of this utility model, it should also be noted that unless otherwise explicitly specified and limited, terms such as "installation," "setting," and "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
