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 design difficulty.

Embodiment Construction

[0045] 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 consists of four parts: liquid 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 hole that is...

Abstract

The invention provides an injection mould for a medical infusion pump body. A mould frame is selected to ensure the convenience of the pouring position setting of a pin-point gate of a product and theautomatic injection production of the product. The structure of the mould frame of the mould adopts a three-plate mould pin-point gate mould frame, and an LKM standard mould frame LKM-DDI-A0-B0-C0 isselected; and based on the space requirement of a demoulding mechanism, the size modification of a moving mould base plate 6 is increased to ensure the installation of the demoulding mechanism.

Description

technical field [0001] The invention relates to the field of injection mold mechanism design, in particular to a three-plate mold point gate injection mold with one mold, two cavities and multiple demoulding mechanisms. Background technique [0002] 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 delivery 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%, so Has a clear market competitive advantage. 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. Therefo...
