Die machine state detecting mechanism of disc machine

This creative department is related to polymer molding processing technology, especially regarding a mold state detecting mechanism of a disk machine.

In the field of polymer molding processing technology, a technical means for providing a specific cavity space shape by a mold and molding the polymer into a predetermined shape in a cavity space is widely used in the prior art. In view of the requirements of different processing methods or shaped articles, many different types of molds are successively disclosed. Further, in order to achieve the purpose of automated continuous production, it is conventionally used to make polymers such as injection devices. The material unit is located at a fixed point position, and most of the molds are carried by a disc machine, and by rotating the disc machine, most of the molds sequentially enter the feeding range of the feeding unit to perform the feeding action. .

Is the mold (1) carried by the disc machine, as shown in the first figure, with a bottom mold (2) as the seat, so that the two side molds (3) (4) are respectively pivoted to the bottom On the opposite side of the mold (2), any one or all of the side molds may be selected according to different processing requirements, and overlapped on the bottom mold (2), according to the bottom mold (2) The required cavity space is formed between the corresponding side molds.

The program-controlled disc machine rotates during the predetermined travel time, so that most of the molds can be circulated at different fixed points of the operating procedure for the different processes, which is the basic of the automated production equipment. Function, but due to different job positioning The process to be carried out in the point is not the same. Take the positioning point of the feeding unit of the injection machine as an example. When the mold is located in the feeding unit, the mold needs to be locked by the die mechanism, and the injected raw material can be closed. The cavity space is molded, so when the predetermined stroke will drive the mold, if the mold (1) is still in the state of being opened or not suitable for the feeding unit, it is not changed. After the appropriate mold state enters the feeding unit, the subsequent dies or shots will be damaged due to the wrong mold state. The damage can be avoided by the emergency stop safety equipment, but These safety devices are activated by humans. If they are not noticed or activated, it is still impossible to avoid damage to the parts.

Therefore, the main purpose of the present invention is to provide a mold state detecting mechanism for a disc machine, which can detect the opening and closing mode of the mold to ensure the safety of work.

Therefore, in order to achieve the above object, the mold state detecting mechanism of the disc machine provided by the present invention comprises a carrier member which is rotated by a shaft as an axis and has an upward bearing surface; most of the molds a ring that is spaced apart from each other along the axis of curvature, and is spaced apart from each other and disposed on the bearing surface, and sequentially passes through a detecting position as the carrier rotates, each of the mold systems respectively having a bottom mold is fixed on the bearing surface, and at least one upper mold is movable between a mold opening position and a clamping position. When the mold clamping position is located, the upper mold is overlapped with the bottom mold. The upper mold is located on one side of the bottom mold; the detecting portion has at least one sensor for sensing the corresponding mold at the detecting position. Whether the upper mold is located at the mold opening position.

The upper mold is pivotally connected to one side of the bottom mold on one side, and the pivoted shaft is pivoted between the mold clamping position and the mold opening position.

The detecting unit further includes a unit disposed at the detecting position and located above the carrying surface, and the sensor is disposed on the seat.

Wherein, the sensor is a photo-electrical sensor.

The detecting portion has a plurality of reflecting sheets disposed on the carrying surface corresponding to a horizontal projection range when the upper mold of the mold is located at the mold opening position.

Please refer to the second to fifth figures. In the preferred embodiment of the present invention, the mold state detecting mechanism (10) of the disc machine is provided, which mainly includes a carrier (20). , a detection unit (30) and a majority of the mold (40).

The carrier (20) is a conventional disc technology for carrying a mold and being driven by external power. In general, the carrier (20) has a supported ring-shaped load. The disk (21) is driven by external power and intermittently rotates with its own center of curvature as an axis, and an appropriate width of the belt-shaped bearing surface (22) is located on the upper side of the carrier (21) for There is no difference between the technology and the known technology, and it will not be repeated.

The detecting portion (30) has a (31) suspension positioned above the carrier (30) at a detecting position and spaced apart from the bearing surface (22), and most of the reflection The pieces (32) are equidistantly spaced from each other on the carrying surface (22), and can sequentially pass through the position of the seat (31) with the rotation of the carrier (21), a first photoelectric detection The detector (33) is disposed on the seat (31), and the detected light is reflected by the corresponding reflective sheet (32) located at the detecting position, and a second photodetector (34) It is disposed on the seat (31) and causes the detected light to be directed toward the annular inner edge of the carrier (21).

Each of the molds (40) is the same as the conventional mold structure disclosed above, and is equally spaced apart from each other on the bearing surface (22), and is rotated with the carrier (21). The molds (40) each have a one-piece bottom mold (41) fixed to the bearing surface (22), a first upper mold. (42) pivoting one side to one side of the bottom mold (41), and pivoting the shaft as an axis to flip between a clamping position and an opening position, when located at the clamping position Attached to the bottom mold (41), when located at the mold opening position, is deployed on one side of the bottom mold (41) and is located above a corresponding reflection sheet (32), a first The two upper molds (43) are pivotally connected to the other side of the bottom mold (41) on one side, and the pivoted shaft is pivoted between a clamping position and an open mold position. In position, it is attached to the bottom mold (41). When it is located at the mold opening position, it is deployed on the other side of the bottom mold (41) and protrudes from the ring of the carrier (21). On the inside of the inner edge.

With the composition of the above components, the mold state detecting mechanism (10) of the disc machine is used as shown in the sixth figure, and the detection position (P1) is selected, and the disc type is emitted. For example, the molding machine is generally selected at a position before the injection position (P2), that is, the stroke of the mold is passed through the detection position and then enters the adjacent injection position, thereby being located at the detection position. The first upper mold (42) corresponding to the mold (40), if it is located at the mold opening position, the first The light emitted by the photodetector (33) will be hindered by the first upper mold (42) and cannot be reflected back, and the corresponding second upper mold (43) is also located at the mold opening position. The location of the second photodetector (34) will also be detected.

Accordingly, the detecting unit (30) may feed back the detected information to the control system of the polymer molding processing machine, and determine whether the mold is in a state suitable for entering the shooting position by a program, if the preset enters the The mold state of the injection position is as shown in the sixth figure, and the first upper mold (42) and the second upper mold are required to be located at the clamping position, or as shown in the seventh figure, the first is required. The upper mold (42) is located at the mold opening position, and the second upper mold (43) is located at the mold clamping position, and the control system can determine whether the mold located at the detection position is detected by the detecting portion (30).
