Detailed Description
The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.
Example one
In consideration of the fact that the ejection holding time is generally a preset period of time in the traditional process of manually placing the insert, in this way, when an emergency occurs and the insert cannot be completely replaced within the ejection holding time, the operator is likely to be clamped by the mold, and life hazards are generated. Meanwhile, the ejection holding time is not flexible enough, and under the condition of insufficient time, the operator can not well check the placement state of the insert. If the inserts are not well placed, the mold is easily damaged. In order to solve the above problem, as shown in fig. 1, the present invention provides an injection molding control method for placing a manual insert, comprising the steps of:
s1: after the injection molding is finished, the ejector pin is controlled to eject the insert after the injection molding is finished, and the safety door is unlocked after the ejection is finished;
s2: judging whether a starting signal is received or not, if so, controlling the thimble to execute a backspacing action, and entering the next step after backspacing to the original point of the thimble;
s3: when the insert to be injection molded is placed in the injection molding chamber again and a safety door locking signal is received, the next step is carried out;
s4: and judging whether a starting signal is received, if so, controlling the injection molding machine to perform an insert injection molding task and returning to the step S1.
In order to ensure that the ejector pin performs the backing action after receiving the starting signal, the ejector pin is in a semi-demolding type, namely the ejector pin stops moving when being ejected to a terminal, and does not perform the backing action, and the ejector pin is controlled to back only after the injection molding machine receives the first starting signal. The specific trigger time of the starting signal is completely selected by an operator, so that the risk of clamping hands of the operator caused by sudden withdrawal of the thimble is avoided.
Meanwhile, because the ejector pin does not need to be worried about to return suddenly, the operator can more safely check the stability of the insert, and the damage of the mold caused by the impact of the unstable insert on the mold is avoided in the insert injection molding process.
In the production process, in order to accelerate the production progress, synchronous production is often performed through injection molding machines arranged in multiple rows, and the existing injection molding machines are usually only provided with a safety door on one side for operation of operators. However, when the operator needs to be responsible for the production operation of multiple devices, the operator is required to patrol multiple devices in multiple rows, which undoubtedly greatly reduces the operation efficiency. In view of the above, the injection molding machine of the invention is provided with the first safety door and the second safety door on two sides of the injection molding chamber respectively, and the first safety door and the second safety door are both provided with the starting keys for triggering the starting signals. When an operator patrols between two injection molding machines, the two injection molding machines can be operated through the safety doors arranged on the two sides of the injection molding chamber, and the increase of the patrol distance caused by the arrangement of the single-side safety door by the operator is reduced.
It should be noted that, when only the first safety door is unlocked, the start button on the first safety door is valid; when only the second safety door is unlocked, the starting button on the second safety door is effective; after the first safety door and the second safety door are locked, the starting keys are all effective.
Further, in order to better manage the operator and avoid the operator from intentionally delaying the operation time, in step S1, after the insert after the injection molding is completed is ejected, the method further includes the step of recording the operation time until the start signal is received in step S4.
Example two
In order to better understand the technical content of the present invention, the present embodiment illustrates the present invention by way of a system structure, as shown in fig. 2, an injection molding control system for artificial insert placement, comprising:
the ejector pin is used for ejecting the insert after injection molding under the control of the main control chip after injection molding is finished;
the safety door is used for entering an unlocking state under the control of the main control chip after ejection is finished, and returning a locking signal to the main control chip after entering a locking state;
the main control chip is used for controlling the thimble to execute a backspacing action after the ejection is finished and the start signal is received, and backspacing to the origin of the thimble;
and the main control chip is also used for placing the insert to be injection molded again in the injection molding chamber, and controlling the injection molding machine to execute the insert injection molding task after receiving the safety door locking signal and the starting signal.
Furthermore, the injection molding machine is provided with a first safety door and a second safety door on two sides of the injection molding chamber respectively.
Furthermore, the starting signal is triggered by a starting key and is respectively arranged on the first safety door and the second safety door.
Further, when only the first safety door is unlocked, the starting key on the first safety door is effective; when only the second safety door is unlocked, the starting button on the second safety door is effective; after the first safety door and the second safety door are locked, the starting keys are all effective.
EXAMPLE III
In order to better understand the contents of the present invention, the present embodiment explains the present invention by a specific case. As shown in fig. 3, a factory needs to produce a batch of products and distribute the products to 12 injection molding machines in a factory, and the injection molding machines are placed in the factory in 4 rows and 3 columns, and two safety doors of each injection molding machine are positioned at two sides in the column direction.
In the production process of the injection molding machines, an operator needs to shuttle among the injection molding machines according to a certain patrol direction to check whether the production of the product in the injection molding machine is finished, and the patrol direction is assumed to be shown as an arrow in fig. 3.
When an operator checks that the injection molding machine on one side finishes injection molding, the safety door of the injection molding machine on one side of the operator can be opened, the ejector pin is in an ejection state and does not return, after the operator takes out a product, the operator triggers the ejector pin to return by pressing a starting button on the safety door on the side, and after the ejector pin returns, a new insert is placed to enter a mold, and the stability of the insert is checked. After the inspection is finished, the safety door is locked by an operator, and a starting signal is triggered through a starting button on the safety door at the side, so that the injection molding machine executes a new injection molding task.
In summary, the injection control method and system for placing the artificial insert, provided by the invention, provide an operation duration capable of performing operation according to the actual operation time for the operator to extract the product and place the insert through triggering of the two start signals, and avoid the problem of hand clamping caused by sudden withdrawal of the thimble in the product taking-out process. Meanwhile, the operation duration is long enough, so that the stability of the insert placement by an operator is ensured, and the safety of the die is ensured.
The chamber both sides of moulding plastics all are equipped with the emergency exit and start the button, and the operation personnel can operate through the emergency exit of both sides simultaneously, and the operation personnel of being convenient for control two machines simultaneously, improve production efficiency. Through the record to the length of the operation, the management of managers is facilitated.
