Problems solved by technology
The method used in the existing published patents is to indirectly check the filling of the melt in the mold cavity by using a metering device connected to each valve or a linear sensor installed on the reciprocating screw of the injection machine to control the gate The sequence of filling the mold cavity often requires repeated testing for each process, and the accuracy is not very high, which brings instability to the quality of the molded product and is prone to produce defective products.

The invention discloses an injection forming intelligent control device, in particular to a melt filling intelligent control device used for injection forming processing, belonging to the field of plastic product forming technology. The melt filling intelligent control device is characterized in that the device comprises a material cylinder, a material hopper which is arranged on the upper part of the material cylinder, a heating coil which is wound on the material cylinder, a screw which is arranged inside the material cylinder and can rotate, a manifold, a plurality of valve devices, a sensor, a control unit and a die; the sensor which is arranged on the profile chamber edge can monitor the filling state of the profile chamber at any moment and transmit a signal to the control unit; the control unit emits a control signal to control the switches of all the valve devices, thus realizing the intellectualized control of the filling process; the valve device is provided with an electromagnetic-typed switch control device and can precisely control the switch of the valve. The melt filling intelligent control device has the effects and benefits of eliminating the melting marks of injection products and improving the quality and strength of product surface.
Description
technical field [0001] The invention belongs to the technical field of plastic product molding, and relates to an injection molding intelligent control device, which is used for intelligently controlling the melt filling process in the injection molding process. Background technique [0002] Large injection molded parts such as automotive dashboards and bumpers are core components in automotive and related fields. With the rapid development of related industries such as automobiles, large injection molded parts such as instrument panels and bumpers are becoming more and more complex and have higher requirements for product quality. Produced by conventional injection molding, it often produces obvious weld lines, warping and other surface defects. In traditional molding, the above problems are usually overcome by increasing the injection pressure, delaying the pressure holding time, or adjusting the structure of the product and the mold, which increases the production cost, ...
