Problems solved by technology

However, the production of medical and pharmaceutical equipment parts, especially plastic parts, not only has high requirements in terms of material performance, but also has more functional requirements in terms of structure and form. Therefore, plastic parts with multiple functional requirements The structural design of the mold is generally more complicated. For these plastic parts, the injection molding production method is generally more complicated, and there is a certain degree of difficulty in the design.

Embodiment Construction

[0046] Figure 1-19 Shown is the relevant explanatory diagram of the present invention; the three-dimensional display diagram of the different orientations of the product structure aimed at by this mold is as follows figure 1 shown. The product is a thin shell, with an average wall thickness of 1.8mm, and the material is modified ABS+PC; the composition of the product is composed of four parts: liquid medicine inlet A, first outlet B, second outlet C, and third outlet D; Product classification design, in figure 1 Under the parting of the main parting line designed in , the mold release design of the product is the difficulty in the mold structure design of this product. These difficulties are as follows: A2 is designed on the basis of the cylindrical shell feature A1 of the liquid inlet A feature , A3, and A4 are three features that affect the demoulding of the product. A2, A3 are the side holes on the A1 cylinder, and A4 is a circular groove on the wall of the A1 cylinder h...

Abstract

The invention provides a medical infusion pump body and a manufacturing method thereof. The medical infusion pump body is characterized in that an X thread mold core sleeves an X middle layer mold core, a driving gear is machined on the X thread mold core, X rack oil cylinder drives the X thread mold core to rotate through an X first transmission gear and an X second transmission gear, a thread lead of the X thread mold core is controlled by an X thread sleeve, when an X mechanism performs core pulling aiming at each feature of the feature C, firstly, the X rack oil cylinder drives the X thread mold core for thread de-molding, and then an X inclined guide column drives an X sliding block for lateral core pulling.

Description

technical field [0001] The invention relates to the field of medical device design, in particular to a medical infusion pump body and a manufacturing method thereof. Background technique [0002] The infusion pump is a device for safe and precise control of infusion. The traditional bottle infusion method uses the potential energy of the liquid as power, and it is difficult to control the infusion speed and volume stably for a long time, while the infusion pump can meet the requirements of high-precision and rapid infusion. [0003] In medical and pharmaceutical equipment, the application of modified plastic parts is more and more extensive. In the solvent preparation equipment, more than 35% of the parts are basically replaced by engineering modified plastic parts. Taking a small solvent separation pump as an example, 48 of its 75 parts are made of modified plastics. After the pump body cover is made of ABS+PC modified plastics, the cost is reduced by nearly 40%. Has a c...
