摘要:
A core element is provided, having the shape of a block with a first surface, a second surface situated opposite the first surface, mutually facing longitudinal side faces, and mutually facing transverse side faces. The first surface is provided with the first groove that is a continuous groove which extends parallel to the longitudinal side faces. The longitudinal side faces are provided with the side wall grooves, the side wall grooves being continuous side wall grooves which extend between the first surface and the second surface and are separated from the first groove in the first surface.

A hydraulic circuit architecture for use in a drive circuit having a hydraulic pump for driving a load is disclosed. The hydraulic circuit architecture includes a flow control valve for controlling a hydraulic fluid flow rate supplied from the hydraulic pump to the load. The hydraulic circuit architecture also includes a hydraulic fluid accumulator arranged in parallel with respect to the flow control valve. Hydraulic circuit architectures having multiple accumulators arranged in parallel with respect to the flow control valve are also disclosed.
摘要:
An injection molding machine that uses a mold and a native controller to operate according to an original mold cycle to mold plastic objects is retrofitted with a retrofit controller; the retrofitted machine uses the mold and the retrofit controller to operate according to a retrofit mold cycle to mold plastic objects. The retrofit mold cycle has a maximum injection pressure that is less than a maximum injection pressure of the original mold cycle. The retrofit mold cycle can also have more constant injection pressures than the original mold cycle.

An injection molding machine that uses a mold and a native controller to operate according to an original mold cycle to mold plastic objects is retrofitted with a retrofit controller; the retrofitted machine uses the mold and the retrofit controller to operate according to a retrofit mold cycle to mold plastic objects. When molding according to the retrofit mold cycle, the injection molding machine can obtain a faster cycle time.
摘要:
An injection molding machine is provided with an injection device, a mold clamping device, an electric storage device configured to supply electric power to the injection device and/or the mold clamping device, and a machine base. The machine base is provided with an upper frame, a lower frame, and support means supporting the upper frame on the lower frame, the injection device and the mold clamping device are disposed on the upper frame of the machine base, and the electric storage device is disposed on the lower frame. The electric storage device is formed of a case body and an electric storage unit therein.
摘要:
An apparatus for controlling the rate of flow of fluid mold material from an injection molding machine to a mold cavity, the apparatus comprising: a manifold having a fluid delivery channel, an actuator interconnected to a valve pin having a tip end drivable between a first position, a second position upstream and a third position upstream of the second position, the actuator and the valve pin being translationally driven by a valve system adjustable between a start position, a plurality of intermediate drive rate positions and a high drive rate position, a pressure sensor and a controller, the pressure sensor sensing a metered pressure of a drive fluid, the controller instructing the valve system to drive valve pin continuously upstream and including instructions that instruct the valve system to move according to a predetermined profile of metered pressures from the start position to selected intermediate drive rate positions and subsequently to the high drive rate position.
摘要:
In an injection molding machine provided with an injection member (injection screw or plunger) having a check valve, a process position of the injection member such as a metering completion position or an injection speed switching position is changed at every predetermined cycle. Thus, it is possible to periodically change a position inside a cylinder which is easy to wear and to reduce the frequency of performing the maintenance of a purging or disassembling and cleaning.
摘要:
A wireless sensor system is described which can be used to measure temperature and/or pressure within an electromagnetically shielded environment. The sensor system includes an embedded processor which intermittently transmits data from the sensors. In electromagnetically shielded environments, the processor transmits the data when the electromagnetically shielding components are moved into a non-shielding configuration.
摘要:
In an injection molding machine, a control instruction value change unit decreases a control instruction value for each axis when a power outage is detected by a power outage detection unit and returns the control instruction value for each axis to an original value when a power recovery is detected by the power outage detection unit.
