Abstract
Description
Technical Field
[0001] The utility model relates to a multi-hole plastic part auxiliary taking and placing mechanism, in particular to a multi-hole plastic part auxiliary taking and placing mechanism. Background Art
[0002] In the process of manufacturing plastic parts: we often encounter large-scale production, multi-cavity molds, and a large number of mold cavities, such as 1 out of 8 cavities, 1 out of 16 cavities, 1 out of 32 cavities, etc. According to the different functions of the products, some customers will require that the products be shipped separately by cavity and box. In the previous fully automatic injection molding production process, the products are usually directly dropped into the lower hopper of the injection molding machine after being ejected from the mold. The parts and gates are mixed in the semi-finished product box. The parts and gates are then manually sorted by the operator, and the parts are mixed and packaged according to the quantity. According to the specific requirements of the customer, the parts that need to be shipped by cavity must be arranged for workers to manually screen in depth. While separating the parts from the gates, the parts must be effectively separated in sequence according to the cavity number, and then packaged. This process is purely manual, which greatly increases the uncertainty. In the process of cavity sorting, some parts themselves are small in size, and the cavity number marked on the product is even smaller. This leads to unclear identification, and some even need to use auxiliary tools to see clearly, which directly increases the risk of mixed product outflow. Due to pure manual operation, sometimes the gate is mixed in the product and cannot be picked up, resulting in the mixing and outflow of the parts packaged for shipment. In terms of product structure, some parts are specified by customers when designing the injection method due to structural reasons, and some are limited in position when designing the layout area. When the product is ejected from the mold, the gate glue channel is easy to damage the parts, but there is no other more effective injection method. Injection molding production can only choose semi-automatic production, manual picking of parts and gates, and the process relies purely on personal experience (proficiency) to complete the picking and opening and closing of the mold. The change points and uncertainty generated increase (when the product has many holes, especially when the quantity is large and a large number of parts need to be ejected from the mold, it cannot be effectively mass-produced). In order to implement the project, it is necessary to invest more in molds, more equipment, and more supporting stations, and increase investment proportionally, which directly affects the company's benefits;
[0003] The difficulty of process control increases sharply during manual operation. The resulting poor outflow leads to customer complaints, requiring explanations and responses to improvement measures (arranging on-site inspections, product returns, full inspections of returned boxes, CP12 processes, and even third-party inspections). This shipping status directly leads to an increase in labor costs, an increase in logistics costs, a decrease in output ratio, and the involvement of a large number of people in rework and sorting, which is time-consuming and labor-intensive.
