Description

Technical Field

[0001] This utility model belongs to the field of mold technology and relates to a hook assembly for mold opening. Background Technology

[0002] A mold is a basic process equipment used in industrial production. Its core function is to shape raw materials (such as metals, plastics, rubber, etc.) into parts of specific shapes and sizes through physical molding under the action of external forces.

[0003] After the mold is processed, it needs to be opened. Existing mold opening methods, such as the three-plate mold with controllable mold opening sequence disclosed in Chinese patent literature [Patent No.: 201320731005.2; Application Announcement No.: CN203567064U], include a moving mold parting plate and a fixed mold parting plate. A second parting plate and a third parting plate are also provided between the moving mold parting plate and the fixed mold parting plate. A square iron is provided at the bottom of the fixed mold parting plate. Three hooks are provided on the mold. The first hook is used to connect the second parting plate and the third parting plate. The second hook is used to connect the third parting plate and the fixed mold parting plate. The third hook is used to connect the moving mold parting plate and the second parting plate.

[0004] This type of mold structure achieves the gradual separation of the moving mold parting plate, the second parting plate, the third parting plate, and the fixed mold parting plate through the first hook, the second hook, and the third hook. However, this type of mold structure has multiple hooks, such as the first hook, the second hook, and the third hook, which are set separately, resulting in a loose structure and occupying a large space. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a hook assembly for mold opening, which solves the technical problem of how to make the hook assembly simple in structure and occupy little space.

[0006] The objective of this utility model can be achieved through the following technical solution: a hook assembly for mold opening, wherein the mold includes a fixed template, a support plate, and a movable template, the movable template being located between the fixed template and the support plate, characterized in that the hook assembly includes a first hook fixedly connected to the fixed template at its top, a second hook fixedly connected to the support plate at its bottom, and a snap-fit ​​block and an elastic element disposed in the movable template, wherein the outer end of the snap-fit ​​block can slide outside the movable template under the elastic force of the elastic element, and the bottom of the first hook can hook the outer end of the snap-fit ​​block. The fixed template is positioned relative to the moving template. The second hook has a long, narrow sliding groove. The first hook is partially embedded in and slidably disposed in the sliding groove. The outer end of the snap-fit ​​block has a pushing surface that is inclined outward and downward. The top of the second hook has an inclined abutment surface that is adapted to the pushing surface. The first hook slides along the sliding groove, causing the pushing surface to contact the first hook and slides along the abutment surface, causing the snap-fit ​​block to overcome the elastic force of the elastic element and retract into the moving template, thus separating the first hook from the snap-fit ​​block.

[0007] During mold opening, the bottom of the first hook engages with the outer end of the locking block. The support plate moves the second hook downwards, while the fixed and moving mold plates remain stationary, separating the support plate from the moving mold plate. Subsequently, the support plate continues to move the second hook downwards, causing the pushing surface to contact the abutting surface. Since both the pushing and abutting surfaces are inclined, the second hook causes the locking block to move inwards against the elastic force of the elastic element until the first hook and the locking block separate. At this point, the moving mold plate begins to move downwards, while the fixed mold plate remains stationary, achieving separation between the moving and fixed mold plates and completing the mold opening. This hook assembly has fewer parts and a simpler structure. The first hook is partially embedded in the sliding groove of the second hook, and the locking block and elastic element are both located in the moving mold plate, making the hook assembly compact and space-saving.

[0008] In the aforementioned hook assembly for mold opening, the bottom of the first hook has a stepped surface, which is located outside the sliding groove. The outer end of the locking block abuts against the stepped surface, causing the bottom of the first hook to hook onto the outer end of the locking block. This structure allows the first hook to hook onto the locking block, and the structure is simple.

[0009] In the aforementioned hook assembly for mold opening, there is a gap between the bottom of the first hook and the moving template, and a gap between the top of the second hook and the fixed template. This structure eliminates the problem of jamming during mold opening, improving the smoothness of mold opening.

[0010] In the above-mentioned hook assembly for mold opening, both the first hook and the second hook are elongated.

[0011] In the aforementioned hook assembly for mold opening, the moving template has a sliding blind hole and two grooves. The two grooves are located on both sides of the sliding blind hole, and the sliding blind hole is connected to both grooves. The snap-fit ​​block and the elastic element are both located in the sliding blind hole. Both sides of the inner end of the snap-fit ​​block have protruding retaining edges. Each of the two grooves is fixed with a baffle plate by bolts. The two baffle plates extend into the two grooves respectively. One end of the elastic element acts on the bottom of the sliding blind hole, and the other end acts on the snap-fit ​​block, so that the outer end of the snap-fit ​​block always tends to extend out of the sliding blind hole. The baffle plate abuts against the baffle plate, preventing the snap-fit ​​block from falling out of the sliding blind hole. This structure facilitates the installation of the snap-fit ​​block and the elastic element.

[0012] In the above-mentioned hook assembly for mold opening, the elastic element is a cylindrical spring or a disc spring, and there are two elastic elements, which are arranged symmetrically.

[0013] Compared with the prior art, the hook assembly for mold opening provided by this utility model has fewer parts and a simpler structure. The first hook part is embedded in the sliding groove of the second hook, and the snap-fit ​​block and elastic element are both located in the moving template, making the hook assembly compact and occupying little space.

Detailed Implementation

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] like Figure 1 , Figure 2 , Figure 4 As shown, the mold includes a fixed template 1, a support plate 2, a movable template 3, and a hook assembly. The movable template 3 is located between the fixed template 1 and the support plate 2. The hook assembly includes a first hook 4, a second hook 5, a snap-fit ​​block 6, and an elastic element 7.

[0022] Both the first hook 4 and the second hook 5 are elongated, with the top of the first hook 4 fixedly connected to the fixed template 1. For example... Figure 3 As shown, the bottom of the first hook 4 has a stepped surface 41, and there is a gap between the bottom of the first hook 4 and the moving template 3. The bottom of the second hook 5 is fixedly connected to the support plate 2, and there is a gap between the top of the second hook 5 and the fixed template 1. The second hook 5 has a long sliding groove 51, and the first hook 4 is partially embedded and slidably disposed in the sliding groove 51, with the stepped surface 41 located outside the sliding groove 51.

[0023] like Figure 5 As shown, the moving template 3 has a sliding blind hole 31 and two grooves 8. The two grooves 8 are located on both sides of the sliding blind hole 31, and the sliding blind hole 31 is connected to the two grooves 8. The snap-fit ​​block 6 and the elastic element 7 are both located in the sliding blind hole 31. Both sides of the inner end of the snap-fit ​​block 6 have protruding retaining edges 62. The two grooves 8 are fixed with baffles 9 by bolts. The two retaining edges 62 extend into the two grooves 8 respectively. One end of the elastic element 7 acts on the bottom of the sliding blind hole 31 and the other end acts on the snap-fit ​​block 6, so that the outer end of the snap-fit ​​block 6 always tends to extend out of the sliding blind hole 31. The retaining edge 62 can abut against the baffle 9 so that the snap-fit ​​block 6 will not fall out of the sliding blind hole 31.

[0024] In this embodiment, the elastic element 7 is a cylindrical spring, and there are two elastic elements 7 arranged symmetrically. In actual production, the elastic element 7 can be a disc spring.

[0025] The outer end of the snap-fit ​​block 6 abuts against the step surface 41 so that the bottom of the first hook 4 can hook the outer end of the snap-fit ​​block 6, thereby positioning the fixed template 1 and the moving template 3. The outer end of the snap-fit ​​block 6 has a pushing surface 61 that is inclined outward and downward, and the top of the second hook 5 has an inclined abutment surface 52 that is adapted to the pushing surface 61.

[0026] When the mold is opened, the bottom of the first hook 4 hooks onto the outer end of the locking block 6. The support plate 2 drives the second hook 5 to move downward. The fixed template 1 and the moving template 3 remain stationary, thus separating the support plate 2 from the moving template 3. Subsequently, the support plate 2 drives the second hook 5 to continue moving downward, causing the pushing surface 61 to contact the abutting surface 52. The second hook 5 causes the locking block 6 to move inward against the elastic force of the elastic element 7 until the first hook 4 and the locking block 6 separate. At this time, the moving template 3 begins to move downward, while the fixed template 1 remains stationary, thus separating the moving template 3 from the fixed template 1 and completing the mold opening.

[0027] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0028] Although this document frequently uses terms such as fixed template 1, support plate 2, moving template 3, sliding blind hole 31, first hook 4, stepped surface 41, second hook 5, sliding groove 51, abutting surface 52, snap-fit ​​block 6, pushing surface 61, stop edge 62, elastic element 7, groove 8, and stop piece 9, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any kind of additional limitation would contradict the spirit of this utility model.
