Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a standardized Luer connector mold structure which can reduce costs. Background Art

[0002] The Luer connector is a very commonly used connector for medical devices. It has the characteristics of quick operation, good sealing, and easy switching. It is widely used. Therefore, the demand for Luer connectors has greatly increased, and the demand for molds used to produce Luer connectors has also increased significantly.

[0003] However, the existing molds for producing and manufacturing Luer connectors have some defects, among which the main defect is reflected in the mold structure for thread removal. The existing mold structure generally occupies most of the position in the mold, making the mold use area and appearance larger, and all aspects of the cost will increase. In addition, because mechanical movement is required for demoulding, the accessories rub and wear against each other, and this type of mold accessories are not standardized in the market, resulting in greatly reduced interchangeability and expensive processing costs, which leads to an increase in a series of subsequent repair and maintenance costs. Utility Model Content

[0004] The purpose of the utility model is to provide a standardized Luer connector mold structure that can reduce costs, so as to solve the problems raised in the above background technology that mechanical movement is required for demoulding, accessories rub and wear each other, and such mold accessories are not standardized in the market, resulting in greatly reduced interchangeability and expensive processing costs, resulting in a series of subsequent repair and maintenance costs.

The stripper plate remains in the rear mold, and the ejector plate of the injection molding machine pushes out the stripper plate. The product shrinks and wraps on the core thread insert stripper plate due to the characteristics of the plastic. When the stripper plate of the Luer connector product is pushed upward through the rifle line principle, the core thread insert stripper plate will rotate to remove the thread. When the core thread insert stripper plate rotates, the gear 1 stripper plate is driven to rotate. Since the gear 1 stripper plate is meshed with the gear 2 stripper plate, the gear 2 stripper plate is driven to rotate while the gear 1 stripper plate rotates, thereby ensuring the uniformity of the core thread insert stripper plate rotation of four products in a group, reducing the mold area occupied by the structure, and reducing a series of subsequent mold manufacturing costs. The related accessories of the mold structure are almost all standard parts with good interchangeability, low cost, and easy replacement, and the later mold maintenance and repair costs are reduced. At the same time, the protective shell, return groove and slide rod can be set upside down inside the protective shell when the mold is not used to prevent dust from falling on the mold when it is placed for a long time. The mold is not disinfected before and after the operation, which may cause the Luer connector to be infected.

The product shrinks and wraps on the core thread insert stripping plate due to the characteristics of the plastic. When the stripping plate of the Luer connector product is pushed upward through the rifle line principle, the core thread insert stripping plate will rotate to strip out the thread. When the core thread insert stripping plate rotates, the gear 1 stripping plate is driven to rotate. Since the gear 1 stripping plate is meshed with the gear 2 stripping plate, the gear 2 stripping plate is driven to rotate while the gear 1 stripping plate rotates, thereby ensuring the uniformity of the core thread insert stripping plate rotation of four products in a group, reducing the mold area occupied by the structure, reducing a series of subsequent mold manufacturing costs, and the related accessories of the mold structure are almost all standard parts with good interchangeability, low cost, and easy replacement, and the later mold maintenance and repair costs are reduced.
