Description

Technical Field

[0001] This utility model relates to the technical field of parts retrieval mechanisms, specifically a parts retrieval mechanism for multi-cavity silicone products. Background Technology

[0002] After the product is injection molded, the injection mold is opened, and the molded part needs to be removed from the mold. The most common removal methods in the existing technology are automated removal by a removal mechanism or manual removal. When the removal mechanism clamps the injection molded part, the injection molded part should have good clamping and positioning points, and the injection molded part should not be too small; while manually prying the injection molded part is inefficient, has a long removal cycle, increases labor costs, and is prone to hand injuries during the prying process.

[0003] Existing part removal methods cannot solve the technical problems of injection molded parts being small and having holes in the middle, making them difficult to clamp or having too small a clamping position. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a part-removing mechanism for multi-cavity silicone products. This mechanism replaces manual prying with fingers, automating the part removal process. It is particularly suitable for demolding and removing small multi-cavity silicone products that are difficult to grip due to holes in the middle or small gripping areas.

[0005] To achieve the above objectives, this utility model provides a picking mechanism for multi-cavity silicone products, including a fixed frame, a driving cylinder, a comb-sliding picking structure, and a sliding plate; the fixed frame has a downward opening and includes two or more fixed upright plates facing each other; several vertical sliding plates are arranged on the inner side of the two fixed upright plates, and several driving cylinders are arranged on the outer side of the two fixed upright plates; the output end of the driving cylinder abuts against the sliding plate; the driving cylinder drives the sliding plate to slide forward to the direction in which the multi-cavity silicone product disengages from the comb-sliding picking structure, which is denoted as the picking direction.

[0006] The driving cylinder of this invention converts air pressure into mechanical energy, which drives the sliding plate to perform linear reciprocating motion. When the part-retrieving mechanism is working, the driving cylinder transfers mechanical energy to the sliding plate, which in turn drives the comb-sliding part-retrieving structure to slide along the part-retrieving direction. After the comb-sliding part-retrieving structure slides a set distance, the multi-cavity silicone product detaches from the structure, thus achieving smooth demolding. This automated part-retrieving mechanism solves the problems of gripping tiny products and the difficulty of manual removal.

[0007] Furthermore, the output end of the drive cylinder is connected to a piston rod; the piston rod passes through the fixed upright plate and extends to the inner side of the fixed upright plate; the end of the piston rod abuts against the sliding plate. After the gas enters the drive cylinder, the airflow pushes the piston, forcing the piston rod to move forward. The end of the piston rod abuts against the sliding plate, and the piston rod pushes the sliding plate. The sliding plate drives the comb-sliding part-removing structure to slide along the part-removing direction until the product is demolded. Through the coordinated arrangement of the drive cylinder and the sliding plate, multi-cavity silicone products can be detached from the comb-sliding part-removing structure. The part-removing mechanism replaces manual prying, realizing automated part removal.

[0008] Further, the comb-sliding part-retrieving structure includes a guide rod, a sliding block, and a combing opening; the sliding block is slidably mounted on the flow channel; combing openings are fixedly connected to both sides of the end of the sliding block; a multi-cavity silicone product to be retrieved is contained within the combing opening; through holes are provided at both ends of the sliding block, and the guide rod passes through the through holes; the combing opening and the multi-cavity silicone product are both connected in series on the guide rod. A drive cylinder drives the sliding plate to move, and the sliding plate drives the comb-sliding part-retrieving structure to move in the part-retrieving direction. The sliding block slides forward along the flow channel, and during the forward sliding process, the sliding block drives the combing opening to move in the part-retrieving direction. When the sliding block slides to a set distance, that is, when the comb-sliding part-retrieving structure slides to the end of the guide rod in the part-retrieving direction, the combing opening and the multi-cavity silicone product are released from the constraint of the guide rod, the multi-cavity silicone product falls from the combing opening, and the part-retrieving mechanism successfully retrieves the multi-cavity silicone product. By placing a multi-cavity silicone product with internal holes inside the comb opening, and then connecting the comb opening and the multi-cavity silicone product in series on the guide rod, the sliding plate pushes the comb-sliding part-removing structure to move along the guide rod in the part-removing direction to the end, thus completing the part removal. This method is especially suitable for demolding and removing small products with holes in the middle and too small clamping space.

[0009] Furthermore, each end of the sliding block is provided with two combing openings; the two combing openings are positioned opposite each other on both sides of the end of the sliding block. By providing two combing openings opposite each other on both sides of the end of the sliding block, and with the two combing openings on the same horizontal line, it is convenient to connect them to the guide rod, resulting in a simple structure and convenient part retrieval.

[0010] Furthermore, four or more sliding plates are provided; the flow channel is provided with several comb-sliding picking structures; each sliding plate can drive at least eight or more comb-sliding picking structures to move in the picking direction. By setting several sliding plates, the picking efficiency is significantly improved, the picking cycle is reduced, and time and labor costs are saved.

[0011] Furthermore, the support feet are provided in eight or more configurations; each support foot has a slot at its top, and the slot contains a receiving groove for accommodating the end of the guide rod. The end of the guide rod away from the picking direction is fixed within the receiving groove.

[0012] Furthermore, the sliding plate has a downward-facing notch at its bottom; the guide rod passes through the notch and extends into the receiving groove. By providing the notch, the sliding plate can drive the comb-sliding part-picking structure to move along the guide rod in the part-picking direction.

[0013] Furthermore, the top of the support foot also includes a locking plate, a locking bar, and a locking block; one end of the locking plate is engaged in the locking groove; a locking bar passes through the middle of the locking plate; the locking plate and the locking bar are cross-connected; the locking block has a hole for the locking bar to pass through; the locking block passes through the locking plate and engages with the locking groove and the receiving groove.

[0014] Through the coordinated arrangement of the slot, locking plate, locking bar, and locking block, the end of the guide rod can be fixed in the receiving groove, and the part-retrieving mechanism can accurately position the comb-sliding part-retrieving structure. The locking bar can lock the locking block from the inside, increasing the locking force of the locking block. The locking plate and locking bar work together to fully lock the slot and receiving groove, preventing the end of the guide rod from slipping out; after part retrieval, pulling the locking bar out along the hole will loosen the locking block, and the guide rod can be removed.

[0015] Furthermore, the fixing frame is equipped with several horizontally oriented fixing posts; the upper end of the sliding plate is provided with a hole, and the fixing posts pass through the sliding plate; both ends of the fixing posts are inserted into the fixing plate. With the fixing posts, the sliding plate can slide along the fixing posts, allowing the drive cylinder to drive the sliding plate to move in the picking direction; the fixing posts also serve to position the sliding plate.

[0016] Furthermore, four or more drive cylinders are provided, and each drive cylinder drives one of the sliding plates to slide. The four drive cylinders independently control the sliding of the sliding plates, resulting in a simple and reliable structure, easy maintenance, and automated part removal.

[0017] Beneficial effects

[0018] This invention utilizes a combination of a driving cylinder, a comb-sliding part-picking structure, and a sliding plate. The driving cylinder transmits mechanical energy to the sliding plate via a piston rod. The sliding plate then moves the comb-sliding part-picking structure in the part-picking direction. After the sliding block moves to a set distance, the multi-cavity silicone product is released from the guide rod and falls from the comb opening. The part-picking mechanism replaces manual prying with fingers, ensuring precise product positioning and automating part-picking. This mechanism is particularly suitable for demolding and removing small, multi-cavity silicone products with holes in the middle that are difficult to grip or have too small a gripping area.

[0019] By setting up several sliding plates, each of which is independently controlled by a drive cylinder, each sliding plate can drive at least eight or more comb-sliding parts-picking structures to move in the picking direction, which significantly improves the picking efficiency, reduces the picking cycle, saves time and labor costs, and the picking mechanism has a simple structure, is easy to operate, easy to maintain, and has a long service life.

The driving cylinder 21 of this invention can convert air pressure into mechanical energy, and the driving cylinder 21 can drive the sliding plate 32 to perform linear reciprocating motion. When the retrieval mechanism is working, the driving cylinder 21 transmits mechanical energy to the sliding plate 32, and the sliding plate 32 drives the comb-sliding retrieval structure 31 to slide along the retrieval direction.
