Embodiment Construction

[0017] Specific embodiments of the present invention will be described in detail below in conjunction with technical solutions and accompanying drawings.

[0018] Injection molding interventional catheter connector, the specific steps of the embodiment are as follows:

[0019] step 1

[0020] Use a drying oven to dry the polymer polymer material at a certain temperature to remove moisture.

[0021] step 2

[0022] Add a certain amount of polymer polymer material to the hopper of the injection molding machine, and set the process parameters such as melt temperature, injection volume, injection rate and injection pressure required for the injection molding process.

[0023] step 2

[0024] The polymer polymer material plasticized into a viscous fluid state is pushed to the end of the barrel by the screw in the barrel, and the melt is injected into the closed mold cavity of the interventional catheter joint through the nozzle at the end of the barrel and the gating system of t...

Abstract

The invention discloses an injection mold of a medical intervention catheter adapter, belonging to the technical field of polymer injection molds. The injection mold is characterized in that a polymer catheter is used as a two-cavity three-plate type injection mold of an insert, and comprises a three-plate type injection mold base, a hydraulic cylinder side core-pulling mechanism, a catheter installing mechanism and a cooling water channel. The injection mold mainly comprises a stationary mould fixing plate, a stripper plate, a fixed mould plate, a movable mould plate, a catheter fixing nail, a movable mould base plate, a reset rod, a top rod retaining plate, a top rod pushing plate, a movable mould fixing plate, a core pressure block, a hydraulic cylinder fixing plate, a hydraulic cylinder, a locking block, a hydraulic cylinder connecting sleeve, a sliding block, a core, a stationary mould cavity insert, a movable mould cavity insert, a cushion block, a sliding block pressure block, a pulling nail, a nylon nail and a cooling water channel. The injection mold has the effects and advantages that the polymer intervention catheter is used as the insert for injecting and forming the catheter adapter, the catheter is connected with the inside of a mould of the catheter adapter, the connecting process of the catheter and the catheter adapter is simplified, and the manufacture cost of the intervention catheter is lowered.

Description

technical field [0001] The invention belongs to the technical field of polymer injection molds, and relates to an injection mold for medical intervention catheter joints. Background technique [0002] Interventional therapy is a minimally invasive treatment using modern high-tech means, that is, under the guidance of medical imaging equipment such as angiography machine, fluoroscopy machine, CT, etc., precision instruments such as medical interventional catheters are introduced into the lumen of human blood vessels. Reaching the internal pathology for diagnosis and local treatment. In interventional therapy, the interventional catheter is not only the transmission channel of the operation, but also the key to the success of the operation. The functions of the interventional catheter mainly include: completing the delivery of subsequent devices, supporting the use of subsequent devices, injecting contrast agents, and monitoring hemodynamic parameters. The material of the in...
