Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a self-locking float. Background Technology

[0002] After assembly, the existing mold extrudes the product in the lower mold. After the product is extruded, it will squeeze the molding cavity and cannot be easily ejected. An ejection mechanism is needed to eject the product and remove it.

[0003] The prior art patent document CN218256978U provides a mold in which bath salt is placed in the cavity and then a pushing mechanism is used to push the pressing block of the ejector device through the first through hole into the assembly groove of the ejector device, thereby pushing the pressing block of the ejector device into the cavity to press the bath salt into a sheet. This method is highly efficient and fast.

[0004] Although the existing technology described above allows for the assembly and use of the lower and upper molds, after the upper mold leaves the lower mold, the product remains inside the molding cavity of the lower mold and is difficult to remove. This makes it difficult to eject the product effectively and does not meet people's needs. Therefore, we need a self-locking float. Utility Model Content

[0005] The purpose of this invention is to provide a self-locking float to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a self-locking float block, including a lower template and an upper template. The inner wall of the upper template is provided with a forming punch, and the inner wall of the upper template is provided with an installation groove. The inner wall of the installation groove is provided with a fixing bolt, and the inner wall of the upper template is detachably connected with a cutting tool. The inner wall of the lower template is fixedly connected with a sliding rod, and the outer wall of the sliding rod is slidably connected with a slider. One end of the sliding rod is fixedly connected with a first spring. The inner wall of the lower template is fixedly connected with a second spring, and one end of the second spring is fixedly connected with a long rod. One end of the long rod is fixedly connected with a fixed float block, and both sides of the fixed float block are fixedly connected with inclined blocks. The inner wall of the lower template is fixedly connected with a forming insert block.

[0007] Preferably, the number of inserts is two, and the vertical lines of the templates with two or more inserts are symmetrically arranged along the axis of symmetry.

[0008] Preferably, the outer wall of the inserter has a bevel, and the top of the slider has a bevel, with the bevel on the inserter matching the bevel on the slider.

[0009] Preferably, the number of sliders is two, and the vertical lines of the template below the two sliders are symmetrically arranged along the axis of symmetry.

[0010] Preferably, the inner wall of the slider is provided with a circular groove, and one end of the slider rod extends into the circular groove, and one end of the first spring is connected to the inner wall of the circular groove.

[0011] Preferably, one end of the slider has an inclined surface, and the inclined surface on the slider matches the inclined surface on the inclined block.

[0012] Preferably, the inner wall of the forming block has an inner hole, and one end of the forming punch extends into the forming block.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0014] This invention allows for easy demolding of products by using an insert tool inserted into the upper and lower mold plates during assembly. The insert tool converts the longitudinal force into a lateral force through the inclined surface, pushing the slider. The inclined surface of the slider then converts the lateral force into a longitudinal force, pushing the fixed float downwards. This facilitates the molding of the product within the mold plate. When the upper mold plate leaves the lower mold plate, the slider returns to its original position. The second spring causes the fixed float to move upwards, ejecting the product and achieving demolding. The operation is simple, the demolding process is smooth, and the demolding efficiency is high, meeting people's needs. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-3As shown, the self-locking float includes a lower template 1 and an upper template 2. The inner wall of the upper template 2 is provided with a forming punch 3, and the inner wall of the upper template 2 is provided with an installation groove 4. The inner wall of the installation groove 4 is provided with a fixing bolt 5, and the inner wall of the upper template 2 is detachably connected with a cutting tool 6. The inner wall of the lower template 1 is fixedly connected with a sliding rod 7, and the outer wall of the sliding rod 7 is slidably connected with a slider 9. One end of the sliding rod 7 is fixedly connected with a first spring 8. The inner wall of the lower template 1 is fixedly connected with a second spring 10, and one end of the second spring 10 is fixedly connected with a long rod 11. One end of the long rod 11 is fixedly connected with a fixed float 12, and both sides of the fixed float 12 are fixedly connected with inclined blocks 13. The inner wall of the lower template 1 is fixedly connected with a forming insert block 14.

[0021] With the above technical solution, when the upper template 2 and the lower template 1 are assembled, the insert 6 is inserted and the longitudinal force is converted into a lateral force through the inclined surface to push the slider 9. Then, the inclined surface of the slider 9 converts the lateral force into a longitudinal force to push the fixed float 12 downward, which facilitates the molding of the product in the molding block 14. When the upper template 2 leaves the lower template 1, the slider 9 is reset. Through the action of the second spring 10, the fixed float 12 moves upward to push the product out, realizing the demolding operation of the product. The operation is simple, the product demolding process is smooth, and the demolding efficiency is high, which meets people's needs.

[0022] Specifically, there are two insert blades 6, and the vertical lines of the template 2 above the two insert blades 6 are symmetrically set along the axis of symmetry.

[0023] Through the above technical solution, during the working process, the inserter 6 can apply force to the slider 9 from two symmetrical positions at the same time, so that the slider 9 can slide smoothly along the slide bar 7 when pushed by the inserter 6, avoiding jamming or deviation.

[0024] Specifically, the outer wall of the inserter 6 has a bevel, and the top of the slider 9 has a bevel, with the bevel on the inserter 6 matching the bevel on the slider 9.

[0025] Through the above technical solution, when the inserter 6 is inserted, the inclined surface on the inserter 6 contacts the inclined surface on the slider 9, converting the longitudinal force of the inserter 6 into the lateral force of the slider 9.

[0026] Specifically, there are two sliders 9, and the vertical lines of the template 1 below the two sliders 9 are symmetrically set along the axis of symmetry.

[0027] Through the above technical solution, similar to the symmetrical arrangement of the inserter 6, the two symmetrical sliders 9 can simultaneously apply force to the fixed float 12 from both sides, ensuring that the fixed float 12 can move down well.

[0028] Specifically, the inner wall of the slider 9 has a circular groove, and one end of the slider 7 extends into the circular groove, while one end of the first spring 8 is connected to the inner wall of the circular groove.

[0029] Through the above technical solution, the cooperation between the slide bar 7 and the slider 9 allows the slider 9 to slide on a defined track, ensuring the accuracy and stability of the slider 9's movement. Furthermore, the circular groove design makes the connection between the slide bar 7 and the slider 9 tighter, reducing the wobbling and offset of the slider 9 during the sliding process. The connection of the first spring 8 provides the power for the slider 9 to reset. When the inserter 6 no longer applies force to the slider 9, the first spring 8 can quickly pull the slider 9 back to its initial position, preparing it for the next operation.

[0030] Specifically, one end of the slider 9 has an inclined surface, and the inclined surface on the slider 9 matches the inclined surface on the inclined block 13.

[0031] With the above technical solution, when the slider 9 moves laterally under the push of the inserter 6, the inclined surface on the slider 9 contacts the inclined surface on the inclined block 13 on both sides of the fixed float 12, converting the lateral force of the slider 9 into the longitudinal force of the fixed float 12, thereby pushing the fixed float 12 to move downward.

[0032] Specifically, the inner wall of the forming block 14 has an inner hole, and one end of the forming punch 3 extends into the forming block 14.

[0033] With the above technical solution, when the upper template 2 and the lower template 1 are assembled, the forming punch 3 extends into the inner hole of the forming insert 14, and together with the forming insert 14, forms a closed space for accommodating and shaping the product.

[0034] In use, the upper template 2 first moves downward to assemble with the lower template 1. Two inserts 6 on the inner wall of the upper template 2 are inserted into the slider 9. Since the outer wall of the inserts 6 has an inclined surface, and the top of the slider 9 also has a matching inclined surface, the insertion of the inserts 6 converts the longitudinal force into a lateral force through the inclined surfaces. This lateral force pushes the two symmetrically arranged sliders 9 to slide along the slide rod 7. The inclined surface at one end of the slider 9 interacts with the inclined surfaces on the inclined blocks 13 on both sides of the fixed float 12, converting the lateral force of the slider 9 back into a longitudinal force, pushing the fixed float 12 downward. Simultaneously, the forming punch 3 moves and extends into the inner hole of the forming insert 14, forming a closed space together with the forming insert 14, facilitating the product's movement within the hole. In the middle molding process, after the product is formed, the upper mold plate 2 moves upward away from the lower mold plate 1, the insert knife 6 moves upward away from the slider 9, the insert knife 6 no longer applies force to the slider 9, the first spring 8 plays a role and quickly pulls the slider 9 back to the initial position, realizing the reset of the slider 9. As the slider 9 resets, the pushing force of the slider 9 on the inclined blocks 13 on both sides of the fixed float block 12 disappears, the second spring 10 plays a role and causes the long rod 11 to move upward. The long rod 11 drives the fixed float block 12 to move upward, and the fixed float block 12 moves upward and pushes the product out of the molding inlet block 14, realizing the demolding operation of the product. This completes all the work. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
