Description

Technical Field

[0001] This utility model belongs to the field of injection mold technology, specifically, it relates to a mold closing and positioning component for injection molds. Background Technology

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding include high production speed and efficiency, automated operation, a wide variety of designs and shapes (from simple to complex), and sizes ranging from large to small. It also produces dimensionally accurate products, facilitates product updates and replacements, and can create complex shapes. Injection molding is suitable for mass production and molding processes involving complex shapes.

[0003] Utility model patent CN214239278U discloses a mold closing and positioning device for injection molds, including a lower mold plate. Positioning sleeves are fixedly installed around the top of the lower mold plate, and guide sleeves are fitted onto the positioning sleeves. An upper mold plate is movably fitted onto the guide sleeves. Positioning rods are movably inserted into the left and right sides of the positioning sleeves, and these positioning rods are inserted into the inner wall of the guide sleeves. A fixing plate is fixedly installed at the end of the positioning rods away from the inner wall of the positioning sleeves. By fixing the positioning sleeves around the top of the lower mold plate, the guide sleeves can be fitted onto the positioning sleeves, thus limiting the position of the guide sleeves. At this time, the upper mold plate can move up and down better on the guide sleeves. Positioning rods are movably inserted into the left and right sides of the inner wall of the positioning sleeves, allowing the positioning rods to be inserted into positioning holes on the inner wall of the guide sleeves relative to the positioning rods. This better limits and fixes the guide sleeves onto the positioning sleeves, making the upper mold plate more stable during operation.

[0004] However, existing positioning devices have their positioning sleeves fixed around the lower mold plate, and the connection position between the guide sleeve and the positioning sleeve is not adjustable, meaning the device can only be used with molds of specific sizes. When it is necessary to change to molds of different sizes or shapes, the relative position of the positioning sleeve and the guide sleeve cannot be adjusted, which may lead to positioning deviations. This requires replacing the positioning components, increasing equipment costs and mold changeover time. In view of this, this utility model is proposed. Utility Model Content

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] A mold closing and positioning component for an injection mold, comprising:

[0007] Adjusting components, which are fixed at both ends of the lower template, are used to adjust the position of the positioning components;

[0008] A positioning element, which is disposed on the adjusting element, is used to guide and position the displacement of the upper mold;

[0009] The guide is fixed at both ends of the upper template and is adapted to the adjusting component. The guide is connected to the upper end of the positioning component and is used to guide the upper template.

[0010] Preferably, the adjusting component includes an extension plate fixed on the lower template. The extension plate has a groove in the middle, and guide grooves are provided on both inner walls of the groove. A damping groove is provided on the lower surface of the extension plate, and the damping groove is located on both sides of the bottom opening of the groove. Reinforcing blocks are fixed on both sides of one end of the lower surface of the extension plate. The reinforcing blocks are fixed to the lower template and are used to reinforce and support the extension plate.

[0011] Preferably, a screw is provided in the slide groove, one end of which is movably connected to the inner wall of one end of the slide groove via a bearing, and the other end of the screw passes through a through groove opened in the inner wall of the other end of the slide groove and extends to the outside of the extension plate. A handle is fixed to the other end of the screw.

[0012] Preferably, the positioning element includes a movable block located in a slide groove, guide blocks are fixed on both sides of the movable block, the guide blocks are located in guide grooves, a threaded groove is formed through the middle of the movable block, the threaded groove is adapted to the screw, and a positioning post is fixed at the middle of the top of the movable block, the positioning post is connected to the guide element.

[0013] Preferably, a stud is fixed at the bottom center of the movable block, a limiting plate is provided below the movable block, a screw hole is opened in the center of the limiting plate, the screw hole and the stud are connected through internal and external threads, a movable handle is provided at one end of the lower surface of the limiting plate for driving the limiting plate to rotate, the upper surface of the limiting plate is set with a frosted structure, and the limiting plate cooperates with the rubber pad in the damping groove to further limit the movable block.

[0014] Preferably, the guide includes a protrusion fixed on the upper template, the protrusion having a slot, the slot being connected through to the positioning post, one end of the slot being an arc-shaped groove, the arc-shaped groove having multiple ball grooves arranged in an arc-shaped array, the ball grooves having balls in them, the balls being in contact with the positioning post to reduce friction.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] The adjusting component of this invention drives the movable block to move horizontally along the slide groove via a screw. With the limiting of the guide block and the guide groove, the horizontal position of the positioning column can be precisely adjusted to meet the positioning requirements of molds of different specifications. It is compatible with a variety of mold sizes and significantly improves the applicability of the device.

[0017] The positioning component of this invention uses friction locking between the limiting plate and the damping groove to further fix the movable block after the positioning post is adjusted into place, thus avoiding positional displacement caused by mold closing vibration and significantly improving stability. At the same time, the guide component has balls installed in the arc groove, which roll in contact with the positioning post, converting sliding friction into rolling friction, greatly reducing resistance and wear during the guiding process, making the upper mold plate more stable when closing the mold. The gap between the positioning post and the empty groove is controlled within a small range. Combined with the point contact guidance of the balls, the mold closing positioning error can be controlled within a very small range, ensuring the dimensional accuracy of the injection molded parts and reducing the generation of scrap due to positioning deviation.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0027] like Figures 1 to 5 As shown, a mold closing and positioning assembly for an injection mold includes an adjusting component 1, a positioning component 2, and a guide component 3.

[0028] Specifically, the adjusting component 1 is fixed at both ends of the lower template and is used to adjust the position of the positioning component 2. The adjusting component 1 includes an extension plate 11 fixed on the lower template. A slide groove 12 is provided in the middle of the extension plate 11. Guide grooves 13 are provided on both sides of the inner wall of the slide groove 12. A damping groove 14 is provided on the lower surface of the extension plate 11. The damping groove 14 is located on both sides of the bottom opening of the slide groove 12. Reinforcing blocks 15 are fixed on both sides of one end of the lower surface of the extension plate 11. The reinforcing blocks 15 are fixed to the lower template and are used to reinforce and support the extension plate 11. A screw 16 is provided in the slide groove 12. One end of the screw 16 is movably connected to the inner wall of one end of the slide groove 12 through a bearing. The other end of the screw 16 passes through the through groove opened on the inner wall of the other end of the slide groove 12 and extends to the outside of the extension plate 11. A handle 17 is fixed to the other end of the screw 16.

[0029] Specifically, the positioning component 2 is set on the adjusting component 1 and is used to guide and position the displacement of the upper mold. The positioning component 2 includes a movable block 21 located in the slide groove 12. Guide blocks 22 are fixed on both sides of the movable block 21. The guide blocks 22 are located in the guide groove 13. A threaded groove 25 is opened through the middle of the movable block 21. The threaded groove 25 is adapted to the screw 16. A positioning post 26 is fixed at the middle of the top of the movable block 21. The positioning post 26 is connected to the guide component 3. A stud 23 is fixed at the middle of the bottom of the movable block 21. A limiting plate 24 is set below the movable block 21. A threaded hole is opened in the middle of the limiting plate 24. The threaded hole and the stud 23 are connected through internal and external threads. A movable handle is set at one end of the lower surface of the limiting plate 24 to drive the limiting plate 24 to rotate. The upper surface of the limiting plate 24 is set with a frosted structure. The limiting plate 24 cooperates with the rubber pad in the damping groove 14 to further limit the movable block 21.

[0030] More specifically, the guide 3 is fixed at both ends of the upper template and is adapted to the adjusting member 1. The guide 3 is connected to the upper end of the positioning member 2 to guide the upper template. The guide 3 includes a protrusion 31 fixed on the upper template. A slot 32 is provided on the protrusion 31. The slot 32 is connected to the positioning post 26. One end of the slot 32 is set as an arc-shaped groove. Multiple ball grooves 33 are arranged in an arc-shaped array in the arc-shaped groove. Balls 34 are provided in the ball grooves 33. The balls 34 fit against the positioning post 26 to reduce friction.

[0031] The extension plate 11 of the adjusting component 1 is fixed to both ends of the lower template. Rotating the handle 17 drives the screw 16 to rotate. The screw 16 engages with the threaded groove 25 of the movable block 21 of the positioning component 2, driving the movable block 21 to move horizontally along the slide groove 12. The guide blocks 22 on both sides of the movable block 21 are embedded in the guide grooves 13 of the slide groove 12, ensuring no deviation during movement and enabling fine-tuning of the horizontal position of the positioning post 26. After moving into position, rotating the movable handle of the limiting plate 24 causes the limiting plate 24 to rise along the stud 23. The frosted structure on its upper surface tightly adheres to the rubber pad in the damping groove 14, locking the position of the movable block 21 through frictional resistance.

[0032] When the upper mold plate descends and closes, the protrusion 31 of the guide member 3 moves synchronously with the upper mold plate, and the slot 32 aligns with the positioning post 26 and fits in. In the arc-shaped groove at one end of the slot 32, the ball 34 rolls in contact with the surface of the positioning post 26, reducing the guiding friction. At the same time, the arc-shaped groove constrains and guides the positioning post 26 to accurately enter the slot 32, correcting minor offsets of the upper mold plate and ensuring that the upper mold plate descends smoothly in the vertical direction.

[0033] The reinforcing block 15 on the lower surface of the extension plate 11 is fixed to the lower template to form a triangular support structure, which enhances the bending resistance of the extension plate 11. The frictional locking between the limiting plate 24 and the damping groove 14, and the rigid constraint between the guide block 22 and the guide groove 13, together ensure that the positioning post 26 is stable in position throughout the mold closing process.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
