A cup of coffee a day is easy to get in modern life. Whether it is a fully automatic coffee machine or a semi-automatic coffee machine, it can make a strong and fragrant coffee. The molds of these coffee machines are an important part of the production process. In order to shorten the mold development cycle, reduce mold costs, and improve mold quality, more and more mold companies have begun to use computer-aided engineering (CAE/CAD) to optimize the structure of injection molds.

Mold design

Mold design refers to the operation personnel using computers and some special injection molding software to complete the production and design of molds. The gating system design and cold material well design are its main forms. CAE technology is widely used in plastic molding simulation. Before the mold is produced, the mold manufacturer can conduct process research and analysis on the CAD model and related products, as well as the mold molding process. This can not only foresee and find out possible defects in advance but also reduce mold scrapping caused by too many mold trials and too long operation time.

The biggest role of Pro/E is to simulate and demonstrate the entire process of mold injection, improve parameters, and make the operation steps simpler for technicians. In fact, as long as the main features of the graphics are set, you can produce good graphics after your own adjustment. The use steps are simple and convenient, which has a positive effect on production.

The pouring system mainly refers to all the routes in the nozzle of the injection molding machine after the material passes through the cavity. The improvement of the pouring system is an extremely critical step in the optimization and improvement of injection molds, and it has a huge impact on the quality of the product. The position of the main flow outlet of the pouring system is in the direction of contact between the nozzle and the cavity. The turning of the diverter should be kept smooth and without protrusions. For longer diverters, cold materials should be loaded at the tail where the pouring gate and the diverter are connected. This is done to prevent the solidification of the molten material from obstructing the pipeline. The location of the gate and how to set the gate are very important. This directly affects whether the mold can complete better filling during the design process, whether the qualified parts produced are qualified, and how long the mold can be used after production.

The design of the cooling system will affect the molding time of the mold in the cavity and determine the quality of the product after the mold is removed. Accurately control the model's taper angle and use the pattern generated during cutting to cast the mold.

Application of coffee machine accessories

Coffee machines on the market are mainly divided into three types: American (traditional drip) coffee machines, Italian (high-pressure pump) coffee machines, and capsule coffee machines. The entire structure of a fully automatic coffee machine is mainly composed of four parts: grinding system, water tank water supply system, boiler heating and insulation system, and extraction system.

The water tank water supply system consists of a water inlet, a water tank, a water level sensor, etc. The water tank is made of injection molds. Users can choose a large cup of coffee, a medium cup of coffee, or a small cup of coffee according to their preferences. After the mold of the water tank is completed, preliminary testing can be carried out. The surface treatment of the appearance parts has been solved during the mold design. When the water level of the water tank is lower than the sensor, the sensor sends a signal to the control system, and the control system issues a command after receiving the signal.

The control system realizes functions such as automatic bean grinding, automatic water filling, automatic extraction, and automatic heat preservation. An operation panel is designed for human-computer interaction, realizing three major functions: coffee concentration control, coffee flow control (large cup of coffee, medium cup of coffee, small cup of coffee), and automatic heat preservation control.
