Description

Technical Field

[0001] The utility model relates to the field of valve plate processing, in particular to an elastic profiling fixture for vertical processing of an injection molding machine valve plate. Background Art

[0002] Chinese Patent with publication number CN220839078U discloses a multi-layer installation universal fixture for an injection molding machine valve plate, including a lower fixture. The lower fixture is connected to an upper fixture through support columns. A plurality of clamping grooves are formed around the lower fixture, and limiting blocks for limiting the valve plate are installed on the clamping grooves. The valve plate is fixed to the lower fixture or the upper fixture by a pressing plate through bolts.

[0003] Before processing the valve plate in the above structure, it is necessary to first select a limiting block according to the size of the valve plate, and then install the limiting block into the clamping groove of the lower fixture or the upper fixture according to the size of the valve plate to achieve the positioning of the valve plate. Then, the pressing plate is placed on the top of two adjacent valve plates, and the position of the pressing plate is adjusted so that the pressing plate can be fixed to the lower fixture or the upper fixture through bolts to clamp the valve plate. If the size of the valve plate to be processed changes, not only does it need to install the limiting block into other clamping grooves, but also it is necessary to replace the limiting plate corresponding to the size of the valve plate, resulting in more cumbersome processing of the valve plate. Summary of the Utility Model

[0004] Aiming at the disadvantages that if the size of the valve plate to be processed changes in the prior art, not only does it need to install the limiting block into other clamping grooves, but also it is necessary to replace the limiting plate corresponding to the size of the valve plate, resulting in more cumbersome processing of the valve plate, the utility model provides an elastic profiling fixture for vertical processing of an injection molding machine valve plate that is convenient for clamping.

[0005] To solve the above technical problems, the utility model is solved by the following technical solutions:

[0006] An elastic profiling fixture for vertical processing of an injection molding machine valve plate includes a bottom plate and a plurality of clamping components arranged on the bottom plate for clamping one valve block respectively. The clamping component includes a fixed profiling fixture fixedly arranged on the upper end surface of the bottom plate, a sliding profiling fixture that is guided to slide on the bottom plate and can approach or move away from the fixed profiling fixture, and a limiting component that limits the sliding of the sliding profiling fixture after the sliding profiling fixture and the fixed profiling fixture clamp the valve plate.

[0007] By adopting the above scheme, the sliding profiling fixture arranged can be guided to slide on the bottom plate, and the limiting component arranged can fix the position of the sliding profiling fixture after the guided sliding, so that valve plates of different sizes can be placed between the fixed profiling fixture and the sliding profiling fixture, making the installation of the valve plate more convenient and improving its applicability at the same time.

[0008] Preferably, the sliding template includes a fixed split mold that can be fixed to the bottom plate under the drive of the first fixing component, and an adjusting component arranged on one side of the fixed split mold close to the fixed template to improve the clamping force.

[0009] Preferably, the adjusting component includes a pushing split mold and an adjusting split mold located between the pushing split mold and the fixed split mold, which can drive the pushing split mold to push towards the fixed template as it descends. The lifting and subsequent limiting of the adjusting split mold are controlled by an adjusting structure.

[0010] With the above scheme, the lifting of the adjusting split mold can be controlled by the provided adjusting structure. When the adjusting structure controls the adjusting split mold to descend, the adjusting split mold will squeeze the pushing split mold at this time, thereby driving the pushing split mold to move towards the direction close to the fixed template, thus increasing its clamping force on the valve plate; when the adjusting structure controls the adjusting split mold to rise, the pushing split mold will lose the extrusion of the adjusting split mold on it. At this time, the pushing split mold can move towards the direction close to the fixed split mold, thereby reducing its clamping force on the valve plate.

[0011] Preferably, one side of the adjusting split mold close to the pushing split mold and one side of the pushing split mold close to the adjusting split mold are respectively set as pressing inclined surfaces with opposite inclined directions and fitting with each other.

[0012] With the above scheme, the pressing inclined surfaces respectively arranged on the adjusting split mold and the pushing split mold can squeeze the pushing split mold when the adjusting split mold moves downward, thereby driving the pushing split mold to move towards the direction close to the fixed template and increasing the clamping force of the pushing split mold on the valve plate placed between the pushing split mold and the fixed template.

[0013] Preferably, the pushing split mold, the adjusting split mold and the fixed split mold are connected in a guiding manner through a guiding structure. The guiding structure includes guiding blocks respectively arranged at both ends of the adjusting split mold close to the pushing split mold and the fixed split mold, and guiding grooves for partial insertion of the guiding blocks and for the guiding blocks to slide therein are arranged on the side walls of the pushing split mold and the fixed split mold close to the adjusting split mold.

[0014] With the above scheme, the lifting of the adjusting split mold can be guided by the provided guiding blocks. At the same time, the guiding block inserted into one end of the fixed template can also pull the pushing split mold to move towards the direction close to the fixed split mold when the adjusting split mold moves upward, thereby reducing the clamping force of the pushing split mold on the valve plate clamped between the pushing split mold and the fixed template, and the valve plate can be taken out from between the fixed template and the sliding template.

[0015] Preferably, the adjusting structure includes a first through hole vertically arranged at the top of the adjusting split mold, a first T-shaped nut embedded and slidable on the bottom plate, and a first bolt that passes through the first through hole and is tightly fitted with the first T-shaped nut.

[0016] With the above solution, when the jacking split die needs to move towards the fixed mold, the first bolt can be rotated towards the inside of the first T-shaped nut. At this time, the first bolt will move downward and squeeze the adjusting split die to move downward. Since there is a pressing inclined surface between the adjusting split die and the jacking split die, when the adjusting split die moves downward, the jacking split die will be pushed by the adjusting split die to move towards the fixed mold, thereby increasing the clamping force of the jacking split die on the valve plate clamped between the jacking split die and the fixed mold.

[0017] Preferably, a return spring is sleeved outside the first bolt and elastically abuts against the adjusting split die and the adjusting nut at both ends.

[0018] With the above solution, the set return spring can push the adjusting split die to move upward for reset when the first bolt flips away from the inside of the first T-shaped nut. At the same time, when the adjusting split die moves upward for reset, it will also pull the jacking split die to move towards the fixed split die. At this time, the clamping force of the jacking split die on the valve plate will decrease, and the valve plate can be taken out from between the fixed mold and the sliding mold.

[0019] Preferably, the limiting component includes a second through hole vertically arranged at the top of the fixed split die, a second T-shaped nut embedded and slidable in the bottom plate, and a second bolt that is tightly fitted with the second T-shaped nut after passing through the second through hole.

[0020] With the above solution, when the second bolt penetrates into the second T-shaped nut, the bottom of the fixed split die will be pressed by the head of the second bolt, so that it is pressed tightly against the top of the bottom plate. At this time, the friction between the fixed split die and the bottom plate will increase, thereby reducing the probability of automatic sliding of the sliding mold; when the second bolt rotates away from the inside of the second T-shaped nut, the fixed split die will lose the extrusion of the second bolt, so that the friction between the fixed split die and the bottom plate will be reduced, and at this time, the sliding mold can slide guided on the bottom plate.

[0021] Preferably, a clamping block and a clamping groove for positioning the installation position of the fixed mold are respectively arranged between the fixed mold and the top of the bottom plate, and a positioning plate for positioning the side wall of the valve plate is detachably arranged at one end of the fixed mold close to the side wall of the bottom plate by screws.

[0022] With the above solution, the clamping groove arranged at the top of the bottom plate can be inserted into the clamping block at the bottom of the fixed mold, so as to position the installation position of the fixed mold, and position the lateral position of the valve plate clamped between the fixed mold and the sliding mold. And the positioning plate installed on one side of the fixed mold by screws can position the longitudinal position of the valve plate clamped between the fixed mold and the sliding mold, so as to facilitate subsequent processing.

[0023] Preferably, a cushion block for placing the valve plate is respectively arranged at one end of the fixed template close to the advancing split mold and at one end of the advancing split mold close to the fixed template.

[0024] With the above scheme, by the cushion blocks respectively arranged at one end of the fixed template close to the advancing split mold and at one end of the advancing split mold close to the fixed template, the bottom plate of the valve plate clamped between the fixed template and the advancing split mold can be supported, so that the bottom of the valve plate is separated from the bottom plate, thereby reducing the influence of the debris generated during the processing of the valve plate on the bottom of the valve plate and the unprocessed valve plates placed subsequently.

[0025] Since the present utility model adopts the above technical scheme, it has remarkable technical effects: the sliding template arranged can guide and slide on the bottom plate, and the limiting component arranged can fix the position of the sliding template after guiding and sliding, so that valve plates of different sizes can be placed between the fixed template and the sliding template, thus making the installation of the valve plate more convenient and improving its applicability at the same time.

[0037] Embodiment

[0038] A vertical processing fixture elastic profile model for an injection molding machine valve plate, referring to Figure 1 , includes a bottom plate 1 and a plurality of clamping components arranged on the bottom plate 1 for clamping a valve block respectively. The clamping components include a fixed profile model 4 fixedly arranged on the upper end surface of the bottom plate 1, a sliding profile model that is guided to slide on the bottom plate 1 and can approach or move away from the fixed profile model 4, and a limiting component that limits the sliding of the sliding profile model after the sliding profile model and the fixed profile model 4 clamp the valve plate 19.

[0039] Referring to Figures 3 - 9 , the sliding profile model includes a fixed split die 6 that can be fixed to the bottom plate 1 under the drive of a first fixing component, and an adjusting component arranged on the side of the fixed split die 6 close to the fixed profile model 4 for increasing the clamping force. The adjusting component includes a pushing-in split die 5 and an adjusting split die 7 located between the pushing-in split die 5 and the fixed split die 6, which can drive the pushing-in split die 5 to push towards the fixed profile model 4 as it descends. The lifting and subsequent limiting of the adjusting split die 7 are controlled by an adjusting structure. The adjusting structure includes a first through hole 801 vertically arranged at the top of the adjusting split die 7, a first T-shaped nut 901 embedded and slidably arranged on the bottom plate 1, and a first bolt 1001 that passes through the first through hole 801 and is tightly fitted with the first T-shaped nut 901. The side of the adjusting split die 7 close to the pushing-in split die 5 and the side of the pushing-in split die 5 close to the adjusting split die 7 are respectively set to be inclined surfaces 11 with opposite inclination directions and in mutual fit. The pushing-in split die 5, the adjusting split die 7, and the fixed split die 6 are connected through a guiding structure. The guiding structure includes guide blocks 20 respectively arranged at both ends of the adjusting split die 7 close to the pushing-in split die 5 and the fixed split die 6. Guide grooves 21 for partially inserting the guide blocks 20 and allowing the guide blocks 20 to slide therein are arranged on the side walls of the pushing-in split die 5 and the fixed split die 6 close to the adjusting split die 7.

[0040] Referring to Figures 4 - 7, a reset spring 12 is sleeved outside the first bolt 1001, and both ends of the reset spring are elastically abutted against the adjusting die splitting 7 and the adjusting nut respectively. In this embodiment, an accommodating space 13 for accommodating the reset spring 12 is arranged inside the adjusting die splitting 7, and both ends of the reset spring 12 are abutted against the first T-shaped nut 901 and the bottom of the accommodating space 13 respectively.

[0041] The limiting component includes a second through hole 802 vertically arranged at the top of the fixed die splitting 6, a second T-shaped nut 902 embedded and slidably arranged in the bottom plate 1, and a second bolt 1002 that passes through the second through hole 802 and is tightly fitted with the second T-shaped nut 902. In this embodiment, a third through hole 803 is arranged on the fixed die holder 4, and the fixed die holder 4 is also detachably arranged on the bottom plate 1 through the limiting component.

[0042] Reference Figures 1 - 2 , a clamping block 16 and a clamping groove 15 for positioning the installation position of the fixed die holder 4 are respectively arranged between the fixed die holder 4 and the top of the bottom plate 1, and a positioning plate 14 for positioning the side wall of the valve plate 19 is detachably arranged at one end of the fixed die holder 4 close to the side wall of the bottom plate 1 through a screw 18.

[0043] Reference Figure 3 , Figures 8 - 9 , a cushion block 17 for placing the valve plate 19 is respectively arranged at one end of the fixed die holder 4 close to the advancing die splitting 5 and one end of the advancing die splitting 5 close to the fixed die holder 4.

[0044] In this embodiment, a plurality of sliding plates 2 with sliding grooves 3 are arranged on the bottom plate 1 at parallel intervals. The first T-shaped nut 901 and the second T-shaped nut 902 are slidably arranged in the sliding grooves 3 on the sliding plates 2. The clamping groove 15 is arranged at the top of the sliding plates 2, and the sliding die holder can slide on the top of the sliding plates 2.

[0045] Specific installation process of the valve plate: When the valve plate 19 needs to be processed, the second bolt 1002 installed on the fixed split mold 6 can be loosened first. At this time, the entire sliding template can slide on the top of the slide plate 2, so that valve plates 19 of different sizes can be installed between the jacking split mold 5 and the fixed template 4, thereby improving its applicability. When the valve plate 19 is installed between the jacking split mold 5 and the fixed template 4, the valve plate 19 will be located above the two cushion blocks 17, thereby reducing the impact of the debris generated during the processing of the valve plate 19 on the bottom of the valve plate 19. At the same time, it can also reduce the frequency required for workers to clean the debris, reducing the workload of the workers. When the valve plate 19 is placed above the two cushion blocks 17, the second bolt 1002 on the fixed split mold 6 can be rotated in the reverse direction at this time, so that the second bolt 1002 moves deeper into the second T-shaped nut 902. At this time, the head of the second bolt 1002 will squeeze the fixed split mold 6, thereby increasing the friction between the fixed split mold 6 and the top of the slide plate 2 and reducing the probability of the automatic sliding of the sliding template. After that, rotate the first bolt 1001 so that the head of the first bolt 1001 pushes the adjusting split mold 7 downward and compresses the return spring 12. Since there are pressing inclined surfaces 11 with opposite inclination directions and in mutual contact between the adjusting split mold 7 and the jacking split mold 5, when the adjusting split mold 7 descends, the jacking split mold 5 will move towards the fixed template 4, thereby increasing its clamping force on the valve plate 19; when the processing of the valve plate 19 is completed, the first bolt 1001 can be rotated in the reverse direction. At this time, the return spring 12 will gradually return to its original position and push the adjusting split mold 7 upward, and the adjusting split mold 7 will pull the jacking split mold 5 towards the direction close to the fixed split mold 6 through the guide block 20 at the end close to the jacking split mold 5. At this time, the clamping force of the jacking split mold 5 on the valve plate 19 will decrease. After that, rotate the second bolt 1002 at the fixed split mold 6 so that the fixed split mold 6 loses the extrusion of the second bolt 1002 on it. At this time, the sliding template will slide on the slide plate 2, and at this time, the valve plate 19 can be removed from between the jacking split mold 5 and the fixed template 4 and replaced with other unprocessed valve plates 19 for processing.

[0046] The above is only the preferred implementation mode of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
