Technical Field

[0001] This application relates to the field of mold equipment technology, specifically to a mold with a reset detection function. Background Technology

[0002] Molds are various molds and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, molds are tools used to make shaped objects. These tools are composed of various parts, and different molds are composed of different parts. They mainly achieve the processing of the shape of the object by changing the physical state of the material being molded.

[0003] In mold casting, a large number of ejector blocks are often needed, both for molding complex structures and for ejecting and demolding products. The ejector blocks are ejected by ejector rods connected below them.

[0004] However, the existing mold closing and resetting process has the following defects: when the ejector block is inserted and reset into the fixed mold, if the ejector block breaks for various reasons (especially small-sized angled ejectors, even with the protection of the protective rod, the angled ejector and the ejector rod connected to it may still break), or the reset between the ejector block and the fixed mold is incomplete, the mold closing between the moving mold and the fixed mold is prone to mold damage, leading to increased losses. Summary of the Invention

[0005] One objective of this application is to provide a mold with a reset detection function that is less likely to damage components during mold closing.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: a mold with a reset detection function, comprising a mold frame, a mold core, and a detection device. The mold core and the detection device are disposed on the mold frame, the detection device is arranged on one side of the mold core, a top block is disposed on the mold core, the top block is adapted to be lifted and protrude from the surface of the mold core, the detection device is adapted to project a detection path from the side onto the top block or above the top block, and the detection path passes through the ejection path of the mold core. When the top block is lifted, it is adapted to trigger the detection path. Along the detection path, the minimum distance between the top block and the detection path is less than the minimum distance between the mold core and the detection path.

[0009] In some embodiments, the first adjusting seat is provided with a first connecting hole, the first connecting hole extends along a first direction, and the first adjusting seat is adapted to provide a plurality of fasteners in the first connecting hole to connect with the fixed seat.

[0010] In some embodiments, the first adjusting seat is provided with an insert groove that mates with the first connecting hole. The insert groove is adapted to accommodate the fastener, and the top of the fastener does not protrude from the insert groove.

[0023] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0025] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0026] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0027] The following description, in conjunction with the accompanying drawings, further illustrates this application:

[0028] like Figures 1 to 5 As shown, this application provides a mold with a reset detection function, including a mold frame 1, a mold core 2, and a detection device 3. The mold core 2 and the detection device 3 are disposed on the mold frame 1, and the detection device 3 is arranged on one side of the mold core 2. The mold core 2 is provided with a top block 4, which is suitable for being lifted and protruding from the surface of the mold core 2. Since the minimum size of the top block 4 in the mold of this application can reach 12mm×12mm, its strength is low. Especially when the top block 4 is a slanted top structure, it is easy to break during mass production and damage the mold. Therefore, it is necessary to use the detection device 3 to sense and identify the state of the top block 4 between mold closing. Considering the use of the mold core 2, the detection device 3 is disposed on the mold frame 1 on one side of the mold core 2 to remotely detect and monitor the reset state between the mold core 2 and the top block 4, which can make the arrangement more flexible and does not interfere with the disassembly and use of the mold core 2.

[0029] The detection device 3 is adapted to project a detection path 31 from the side onto the top block 4 or above the top block 4 (in this application, the projection path is generally a straight line), and the detection path 31 passes through the ejection path of the mold core 2. When the top block 4 is lifted, it is adapted to trigger the detection path 31. For example, when the top block 4 is lifted, it can block and block the detection path 31. When the detection device 3 senses the distance detected by the detection path 31 or the change in the state of the detection path 31, it is considered to have identified the top block 4. Then, it transmits a signal to the injection molding machine through light to prevent subsequent actions, including mold closing, in order to protect the mold.

[0030] Along the detection path 31, the minimum distance x between the top block 4 and the detection path 31 is less than the minimum distance between the mold core 2 and the detection path 31. This is to reduce the probability of contact interference between the mold core 2 and the detection path 31, and to improve the success rate of the detection path 31 in effectively identifying the state of the top block 4. It can also be understood that by designing the structure of the mold core 2 and the arrangement of the detection path 31, the mold core 2 can avoid the detection path 31, so that the detection path 31 can detect the top block 4 without interference from the mold core 2.

[0031] In some embodiments, the shortest distance between the detection path 31 and the top block 4 is no more than 2 mm. When the top block 4 breaks or the distance to complete reset exceeds 2 mm, the detection device 3 can prevent the mold from closing, protect the safety of the top block 4 and mold core 2 and other components, and prevent them from being crushed.

[0032] In some embodiments, the detector 35 includes a photoelectric sensor that can remotely identify the distance between the detector 35 and the top block 4 by using photoelectric signal conversion. The identification is relatively accurate. When the top block 4 blocks and obstructs the detection path 31, the detector 35 can sense the change and emit a signal.

[0033] Furthermore, the photoelectric sensor is a diffuse reflection photoelectric sensor. Within the detection distance of the photoelectric sensor, the structure of the mold frame 1 and the mold core 2 is adapted to avoid the detection path 31, so as to avoid affecting the recognition accuracy of the photoelectric sensor.

[0034] In some embodiments, the detection path 31 is close to the surface of the mold core 2, but does not contact the surface of the mold core 2. When the detection path 31 detects the top block 4, it means that the top block 4 has not been reset.

[0035] In some embodiments, the detection path 31 is directly projected onto the top block 4. When the detection path 31 detects that the distance between itself and the top block 4 exceeds the error value, it indicates that the top block 4 has not been reset.

[0036] like Figures 3 to 5 In the illustrated embodiment, the detection device 3 includes a fixed base 32, a first adjusting base 33, a second adjusting base 34, and a detector 35. The fixed base 32 is fixedly mounted on the detection device 3. The first adjusting base 33 is slidably mounted on the fixed base 32 along a first direction. The second adjusting base 34 is slidably mounted on the first adjusting base 33 along a second direction. The detection device 3 is fixedly mounted on the second adjusting base 34. When the detector 35 is installed, the detector 35 can adjust its relative position to the top block 4 through the first adjusting base 33 and the second adjusting base 34 to ensure that the detection path 31 can be projected to the preset position in the correct state. When the mold core 2 and the top block 4 are replaced, the first adjusting base 33 and the second adjusting base 34 can also be used to recalibrate the detection path 31 projected by the detector 35 to ensure the accuracy of the sensing.

[0037] like Figure 4In the embodiment shown, the first direction and the second direction are parallel to the same plane, so that when the detector 35 is adapted to move through the first adjustment seat 33 and the second adjustment seat 34, the detection path 31 is located in the same detection plane, and the minimum distance between the top block 4 and the detection plane is less than the minimum distance between the mold core 2 around the top block 4 and the detection plane. When the detector 35 is installed, the detector 35 can adjust the front-back and left-right distance between itself and the top block 4 through the first adjustment seat 33 and the second adjustment seat 34, so as to ensure that the detector 35 can more accurately sense the reset state of the top block 4.

[0038] Understandably, the height of the detection plane can be varied by setting mounting bases 32 with different thicknesses (heights).

[0039] like Figure 4 and 5 In the embodiment shown, the first adjusting seat 33 is provided with a first connecting hole 331, which extends along a first direction. The first adjusting seat 33 is adapted to be provided with a plurality of fasteners in the first connecting hole 331 and connected to the fixed seat 32. The plurality of fasteners can restrict the first connecting hole 331 from rotating, so that the first adjusting seat 33 can only slide and adjust along the first direction after the fasteners are loosened, thereby improving the connection stability between the first adjusting seat 33 and the fixed seat 32.

[0040] like Figure 4 and 5 In the embodiment shown, the first adjusting seat 33 is provided with an insert groove 332 that matches the first connecting hole 331. The insert groove 332 is suitable for accommodating fasteners. The top of the fastener does not protrude from the insert groove 332. The fastener at the first connecting hole 331 on the first adjusting seat 33 is a hidden design, which can reduce the probability of interference between the first adjusting seat 33 and the second adjusting seat 34 during relative movement, thereby improving the overall structural compactness and stability.

[0041] like Figure 4 and 5 In the embodiment shown, the second adjusting seat 34 is provided with a second connecting hole 341, which extends along a second direction. The second adjusting seat 34 is adapted to be provided with a plurality of fasteners in the second connecting hole 341 and connected to the first adjusting seat 33. The plurality of fasteners can restrict the second connecting hole 341 from rotating, so that the second adjusting seat 34 can only slide and adjust along the second direction after the fasteners are loosened, thereby improving the connection stability between the first adjusting seat 33 and the second adjusting seat 34.

[0042] like Figure 4 and 5In the embodiment shown, the first adjusting seat 33 and the second adjusting seat 34 are respectively provided with a guide rail 333 and a guide rail groove 342. The guide rail 333 and the guide rail groove 342 are slidably connected along the second direction to improve the stability and accuracy of the relative movement between the first adjusting seat 33 and the second adjusting seat 34, and to avoid misjudgment caused by the second adjusting seat 34 shaking and affecting the detection accuracy of the detection path 31.

[0043] In some embodiments, a protrusion 21 is provided on the mold core 2, the protrusion 21 is higher than the mold frame 1, the top block 4 is located on the protrusion 21, at least a portion of the top block 4 is higher than the mold frame 1, and the detection device 3 is horizontally arranged on the mold frame 1 around the mold core 2, with the first direction and the second direction parallel to the horizontal plane. The top block 4 is higher than the protrusion 21 in at least one direction of the horizontal plane. By optimizing the structural design of the mold core 2 and the mold frame 1, the arrangement of the detection device 3 and the detection of the top block 4 are more convenient, and it is less likely to cause structural interference with the mold core 2 and the mold frame 1. With the horizontal plane as a reference, the calibration and adjustment of the detection path 31 is easier, and the detection difficulty is reduced.
