Problems solved by technology

The current status quo is basically that different manufacturers use different control computers, and to a large extent they are mainly developed by themselves, so that different software development platforms, hardware interfaces and development systems are used, making it difficult to unify the operating standards of control computers
At the same time, the process flow in the existing control program is often relatively simple, and it is basically impossible to operate for different processes or slightly complicated process operations

Embodiment 1

[0031] Such as figure 1 As shown, the liquid silicone injection molding control system of the present invention includes a control module 1 and a man-machine operation module 2, and the control module 1 is electrically connected to the man-machine operation module 2; wherein the control module 1 serves as the core The module is used to control the mold opening and closing operation, sliding mold operation, pin positioning operation, air blowing operation, film holding operation, feeding operation, glue pumping operation, injection base operation and glue injection operation of liquid silicone injection molding equipment; The internal core program is based on the secondary development of the underlying program system of Taiwan Baoyuan Computer, which is suitable for horizontal liquid silicone rubber programming machines, vertical single-slide liquid silicone rubber injection molding machines, and vertical double-slide liquid silicone rubber injection molding machines. machine, ...

Embodiment 2

[0040] The only difference between this embodiment and Embodiment 1 is that in the production method of the liquid silicone injection molded product, an action interlocking step is added, which is specifically:

[0041] The mold opening and closing operation, sliding mold adjustment operation, pin positioning operation, air blowing operation, film holding operation, material feeding operation, glue pumping operation, injection seat operation and glue injection operation are all controlled by internal relays, only all actions are OFF The interlocked internal relay can only be ON when in the state, and the internal relay is OFF when any action is executed; only when the internal relay is in the ON state can the output action be executed, and the action will be self-maintained for continuous output after output, while the internal The relay is in the OFF state, and other actions cannot be output, realizing the interlock function.

[0042] This step can more effectively ensure tha...

Embodiment 3

[0044] The difference between this embodiment and Embodiment 1 is that in the production method of the liquid silicone injection molded product, an automatic mold adjustment step is added, which is specifically:

[0045] Firstly, the horizontal liquid silicone rubber programmer executes the rough mold clamping action with the mold adjustment parameters of small pressure and speed. After the data of the electronic scale is no longer small, perform a rough return to zero action, so that the mold clamping scale obtains a value close to the thickness of the mold. First align the zero position; then the horizontal liquid silicone rubber programmer executes the mold opening action to move a certain distance, and then executes the mold closing action, and performs the mold closing high pressure action to make the horizontal liquid silicone rubber programmer lock the mold After the mold is locked, the control module resets the position of the mold clamping ruler to zero to obtain the a...

Abstract

The invention discloses a liquid silica gel injection molding control system. The system comprises a control module and a man-machine operation module. The control module is electrically connected to the man-machine operation module. The invention also discloses a method for producing a liquid silica gel molded product. The method comprises the following steps of building a production flow process by control program pre-written by the man-machine operation module, storing the production flow process in a memory of the control module, inputting control parameters into the man-machine operation module, according to production demand, calling the production flow process stored in the memory, by the control module, transmitting an instruction for starting a liquid silica gel injection molding device, and carrying out corresponding processes by the liquid silica gel injection molding device according to the written production flow process and set motion control parameters to produce the corresponding liquid silica gel molded product. The system has the characteristics of good functions and good compatibility.

Description

technical field [0001] The invention relates to a control system, in particular to a liquid silica gel injection molding system and a method for producing liquid silica gel molded products. Background technique [0002] Injection molding machine is a kind of plastic machinery, referred to as injection machine or injection molding machine, is the main molding equipment for making thermoplastic or thermosetting materials into plastic products of various shapes by using plastic molding molds. Injection molding is achieved through injection molding machines and molds. Most of the existing liquid silicone injection molding machines are modified by using ordinary injection molding machines with imported liquid silicone feeders. The current situation basically is that different manufacturers use different control computers, and to a large extent they are self-developed, so that different software development platforms, hardware interfaces, and development systems are used, making ...
