Description

96-well reagent plate mold exhaust mechanism

technical field

The utility model relates to an exhaust mechanism of a 96-hole reagent plate mold, which belongs to the field of injection molds.

Background technique

Using injection molds to produce plastic products, such as a medical 96-well reagent plate, when traditional molds produce 96-well reagent plates, due to the moisture in the plastic raw material (PP), irregularities will appear on the product during injection molding. Bubbles, the bubble parts will break, resulting in unqualified product quality.

Contents of the invention

The purpose of the utility model is to overcome the shortcomings of the prior art, and provide a 96-hole reagent plate mold exhaust mechanism that adopts a ventilating steel insert structure to discharge excess water from the ventilating steel and ensure product quality.

The technical scheme of the exhaust mechanism of the 96-hole reagent plate mold of the present invention is as follows: it includes the mold fixed mold bottom plate and the movable mold bottom plate, the fixed mold fixed plate is installed under the fixed mold bottom plate, the fixed mold plate is installed under the fixed mold fixed plate, and the movable mold bottom plate is installed. The movable mold fixed plate is equipped with a movable template, which is characterized in that a fixed mold insert is installed in the fixed template, a breathable steel insert is installed on the fixed mold insert, and the fixed mold insert is in contact with the breathable steel insert The exhaust groove is set on the surface of the ventilating steel insert, and the cavity is set on the breathable steel insert. The movable mold insert is installed on the bottom plate of the movable mold. Core, the core matches the cavity.

The exhaust mechanism of the 96-hole reagent plate mold of the utility model is mainly characterized in that a breathable steel insert is installed on the fixed mold insert, an exhaust groove is arranged on the contact surface of the fixed mold insert and the breathable steel insert, and the breathable steel insert It is an insert made of a material with breathable function, commonly known as breathable steel, which is available on the market. When the product is pressure-packed and formed, a relatively large pressure is generated in the mold, and the injected plastic raw material is squeezed, held, and Shaping, through extrusion and pressure keeping, the water in the plastic raw material can be extruded through the breathable steel insert in the form of steam, and then discharged out of the mold through the exhaust groove, so that no air bubbles appear on the product, and the qualified rate and quality of the finished product can be improved. , Improve product quality.

The exhaust mechanism of the 96-hole reagent plate mold of the utility model has 6-10 rows of exhaust grooves, which are evenly distributed on the contact surface of the fixed mold insert and the breathable steel insert, and the exhaust effect of multiple exhaust grooves it is good. Cooling water holes are formed in the movable mold insert and the mold core to prevent the temperature rise of the movable mold insert from being too high, and at the same time facilitate the cooling and shaping of the product after molding.

detailed description

The utility model relates to a 96-hole reagent plate mold exhaust mechanism, as shown in Figure 1 and Figure 2, comprising a fixed mold bottom plate 1 and a movable mold bottom plate 2, a fixed mold fixed plate 3 is installed under the fixed mold bottom plate, and the fixed mold is fixed The fixed formwork 4 is installed under the plate, the movable formwork fixed plate 5 is installed on the movable formwork bottom plate, the movable formwork 6 is installed on the movable formwork fixed plate, the fixed formwork insert 7 is installed in the fixed formwork 4, and the breathable air is installed on the fixed formwork insert 7 Steel inserts 8, exhaust grooves 9 are set on the contact surface of fixed mold inserts 7 and air-permeable steel inserts 8, mold cavities 10 are set on the air-permeable steel inserts 8, and movable mold inserts are installed on the movable mold bottom plate 2 11. The movable mold insert passes through the movable mold fixed plate 5 and the movable template 6, and the movable mold insert 11 is provided with a core 12, and the mold core 12 is matched with the cavity 10. The main feature of this scheme is to install a breathable steel insert 8 on the fixed mold insert 7, and to set an exhaust groove 9 on the contact surface of the fixed mold insert 7 and the breathable steel insert 8. The breathable steel insert is a kind of air-permeable Inserts made of functional materials, commonly known as breathable steel, are available on the market. When the product is pressurized and formed, a large pressure is generated in the mold, and the injected plastic raw material is extruded, maintained, and shaped. , keeping the pressure, the moisture in the plastic raw material can be extruded through the air-permeable steel insert 8 in the form of steam, and then discharged out of the mold through the exhaust groove 9, so that no air bubbles appear on the product, improve the qualified rate and quality of the finished product, and improve the product grade. There are 6-10 rows of the exhaust grooves 9, which are evenly distributed on the surface where the fixed mold insert 7 and the air-permeable steel insert 8 contact, and the multiple exhaust grooves have a good exhaust effect. Cooling water holes 13 are formed in the movable mold insert 11 and the core 12 to prevent the temperature rise of the movable mold insert from being too high, and at the same time facilitate the cooling and setting of the product after molding.
