Description

Technical Field

[0001] This utility model relates to the field of ceramic molding machine technology, and in particular to a multifunctional in-mold locking plate mechanism. Background Technology

[0002] To improve the quality and production efficiency of sanitary ceramic blanks, high-pressure injection molding machines are gradually replacing medium- and low-pressure injection molding equipment. However, existing high-pressure molding machines using in-mold locking mostly employ locking plate mechanisms and safety pin mechanisms, resulting in complex mechanisms and high costs. Patent CN202420825275.8 discloses a high-pressure molding machine with an in-mold locking structure. During operation, this machine relies on a magnetic switch on the cylinder for detection. When the cylinder is extended and the mandrel becomes loose or damaged, the sliding plate disconnects from the telescopic cylinder, but the main equipment continues to operate. This poses a risk of the moving substrate being overturned or the clamping cylinder being damaged. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a multifunctional in-mold locking insert mechanism. The insert mechanism realizes the functions of in-mold locking and safety pin, and has a simple structure and low cost.

[0004] To achieve this technical objective, the present invention adopts the following solution:

[0005] A multifunctional in-mold locking insert mechanism includes an insert support, a sliding insert, a top head, a telescopic cylinder, and an insert limiting block. The insert support is installed on both sides of the moving base plate of the high-pressure molding machine. The insert limiting block is located on the top of the insert support and forms a slide rail with the insert support. The sliding insert is slidably connected to the slide rail. The inner side of the sliding insert is connected to the top head, and the top head is connected to the piston rod of the telescopic cylinder. The telescopic cylinder is installed on the top of the moving base plate. A proximity switch is provided on one side of the telescopic cylinder.

[0006] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0007] This invention features both in-mold locking and a safety pin, eliminating the need for a safety pin mechanism compared to ordinary high-pressure molding machines. This reduces the cost of the safety mechanism, minimizes the space occupied by the safety pin mechanism, and lowers the overall complexity of the mechanism. The mounting surface of the movable base plate is stepped; during locking, the stepped sections primarily support the plate support, avoiding the risk of shear force due to loose bolts and reducing overall structural deformation. A proximity switch is added to one side of the telescopic cylinder, working in conjunction with a magnetic switch on the cylinder to detect and prevent safety risks caused by loose or damaged mandrels.

[0008] Furthermore, the two sides of the movable base plate are mounting surfaces, which are stepped, and the insert plate support is connected to the mounting surfaces by bolts.

[0009] Furthermore, a T-shaped groove is provided on the inner side of the sliding plate, and the top head is installed in the T-shaped groove.

[0010] Furthermore, a detection switch is provided on the upper part of the insertion plate limit block.

[0011] Furthermore, the high-pressure forming machine includes a frame column, with a safety insertion hole on the top of the frame column.

[0012] Furthermore, a clamping cylinder is installed on the inner side of the frame column, and a cylinder head is provided at the top of the telescopic rod of the clamping cylinder.

[0013] Furthermore, the insert plate support has a round hole through which the telescopic rod of the pressing cylinder and the cylinder head pass. The sliding insert plate is U-shaped, with the U-shaped opening facing outward and corresponding to the telescopic rod of the pressing cylinder. The width of the U-shaped opening is smaller than the diameter of the cylinder head. Attached Figure Description

Detailed Implementation

[0021] To fully understand the purpose, features and effects of this utility model, the following specific embodiments will be used to describe this utility model in detail, but this utility model is not limited thereto.

[0022] It should be noted that when a component is referred to as "fixed to" or "set on" another component, it can be directly on or indirectly on the other component. When a component is referred to as "connected to" or "laid on" another component, it can be directly connected to or indirectly connected to the other component.

[0023] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or 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. Therefore, they should not be construed as limitations on this application.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" or "several" means two or more, unless otherwise explicitly specified.

[0025] See Figures 1 to 5 This utility model provides a multifunctional in-mold locking insert mechanism, which is applied in a high-pressure molding machine 14. The high-pressure molding machine 14 includes a movable base plate 1, and a guide assembly 7 is installed on the top of the movable base plate 1 to provide guidance for the movement of the movable base plate 1. Frame columns 10 are provided on both sides of the high-pressure molding machine 14. A safety insertion hole 11 is opened on the top of the frame columns 10. A clamping cylinder 8 is installed on the inner side of the frame columns 10. A cylinder head 9 is provided on the top of the telescopic rod of the clamping cylinder 8.

[0026] This utility model relates to a multifunctional in-mold locking insert plate mechanism, comprising an insert plate support 2, a sliding insert plate 3, a top head 4, a telescopic cylinder 5, and an insert plate limiting block 6. The insert plate support 2 is mounted on mounting surfaces 12 on both sides of a movable base plate 1. The mounting surfaces 12 are designed in a stepped shape, and the insert plate support 2 is connected to the mounting surfaces 12 by bolts. The mounting surfaces 12 of the movable base plate 1 and the insert plate support 2 are pressed tightly together by bolts. During locking, the stepped sections mainly support the insert plate support 2, avoiding the risk of shear force due to bolt loosening, and reducing the overall structural deformation. The insert plate support 2 has a circular hole through which the piston rod and cylinder head 9 of the pressing cylinder 8 pass.

[0027] The top two sides of the insert plate support 2 are provided with insert plate limiting blocks 6, which form a slide rail with the insert plate support 2. The sliding insert plate 3 reciprocates within the slide rail. A detection switch 15 is provided on the upper part of the insert plate limiting block 6 to detect the signal of the cylinder head 9. When the cylinder head 9 extends, the detection switch 15 transmits the signal to the controller, and the controller issues an instruction based on the signal. The detection switch 15 is prior art and will not be described in detail here. The sliding insert plate 3 is U-shaped with an outward opening that corresponds to the piston rod of the pressing cylinder 8. The width of the U-shaped opening is smaller than the diameter of the cylinder head 9. A T-shaped groove is provided on the inner side of the sliding insert plate 3. The top head 4 is installed in the T-shaped groove and is connected to the piston rod of the telescopic cylinder 5. The telescopic cylinder 5 is installed on the top of the movable base plate 1.

[0028] A proximity switch 13 is installed on one side of the telescopic cylinder 5. The proximity switch 13 and the magnetic switch on the telescopic cylinder 5 work together for detection. When the sliding plate 3 retracts into position with the lever of the telescopic cylinder 5, if the top head 4 becomes loose or damaged, causing the sliding plate 3 to disconnect from the lever of the telescopic cylinder 5, the magnetic switch in the retracted position of the telescopic cylinder 5 will give a signal, but the proximity switch 13 will not detect the sliding plate 3 and will not give a signal. The equipment will then stop and sound an alarm to remind the operator to handle the situation, thereby avoiding such safety risks.

[0029] The locking function of the multifunctional in-mold locking insert mechanism of this utility model is as follows: (See attached diagram) Figure 3 The telescopic cylinder 5 is initially retracted, and the clamping cylinder 8 is initially extended. When the movable base plate 1, with its movable end model attached, moves under the guidance of the guide component 7 until it closes with the fixed end model, the cylinder head 9 passes through the circular hole of the insert plate support 2. The detection switch 15 detects a signal and transmits it to the telescopic cylinder 5. The telescopic cylinder 5 receives the signal and begins to extend, stopping at the mid-position. The clamping cylinder 8 receives the signal and begins to retract until the cylinder head 9 presses against the sliding insert plate 3, thus forming an in-mold locking structure.

[0030] The working process of the safety pin function of the multifunctional in-mold locking plate mechanism of this utility model is as follows: See Figure 5 The telescopic cylinder 5 is initially retracted. When the movable base plate 1 and the movable end model move to full mold opening under the guidance of the guide component 7, the sliding insert 3 is directly opposite the center of the safety socket 11. The telescopic cylinder 5 receives a signal and begins to extend until it is fully extended. At this time, the sliding insert 3 passes through the safety socket 11 and acts as a safety pin to prevent the movable base plate 1 and the movable end model from suddenly falling and causing a safety accident due to aging or damage to other structures of the molding machine when opening the mold or changing the model.

[0031] Finally, it should be noted that the above-listed embodiments are merely preferred embodiments of the present invention. Of course, those skilled in the art can make modifications and variations to the present invention. If such modifications and variations fall within the scope of the claims of the present invention and their equivalents, they should be considered as being within the protection scope of the present invention.
