Description

Technical Field

[0001] This utility model relates to the field of mold processing technology, specifically a positioning device for mold processing. Background Technology

[0002] Mold processing refers to the process of using specialized mechanical equipment to process mold materials and manufacture mold tools that can produce parts or products. The molds produced are used to form and cast different workpieces. The molds are then used to manufacture various components through precision machining equipment and assembled. During the manufacturing process, strict control of dimensions and precision is required to ensure the quality of the molds.

[0003] The utility model with publication number CN221735428U discloses a positioning and locking structure for mold processing. Screws are provided through both ends of the locking seat and through both ends of the locking block. The screws partially penetrate the locking seat. It is suitable for positioning and locking of larger molds. The positioning and locking component two includes a placement groove, a threaded bar is provided in the placement groove, and a locking plate is also provided in the placement groove. The lower end of the locking plate has a threaded groove, and the threaded bar is rotatably disposed in the threaded groove. It is suitable for positioning and locking of smaller molds.

[0004] However, the above-mentioned positioning and locking structure used in mold processing still has the following problems in actual use: Although the positioning and locking are achieved by bolts according to the mold specifications, this type of positioning and locking mechanism requires manual use of bolts to achieve tight positioning. The positioning positions cannot be symmetrically matched, which makes the locked mold subject to different forces and prone to falling off. At the same time, the length and width ratios of molds of different specifications are different, and it is difficult to effectively guarantee the positioning effect by longitudinal positioning alone, which affects the positioning effect during mold processing.

[0005] Therefore, we propose a positioning device for mold processing to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a positioning device for mold processing. It solves the problem that the positioning and locking mechanism uses bolts to lock the mold according to its specifications. However, such positioning and locking mechanisms require manual use of bolts to achieve tight positioning. The positioning positions cannot be symmetrically matched, which makes the locked mold subject to different forces and prone to falling off. At the same time, the length and width ratios of molds of different specifications are different, and it is difficult to effectively guarantee the positioning effect by using only longitudinal positioning, which affects the positioning effect during mold processing.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a positioning device for mold processing, comprising a support base and a positioning platform fixedly installed at the center of the top surface of the support base; further comprising:

[0008] The positioning platform is equipped with an adjustment mechanism, which includes a drive worm gear, and a drive worm wheel is engaged in the middle of the inner side of the drive worm gear.

[0009] The positioning platform has a positioning mechanism on its top surface, which includes a positioning slider. The inner side of the positioning slider is equipped with an abutting arc plate, and the positioning sliders, which are set at equal angles, are equidistant from the center point of the support base.

[0010] Preferably, the adjustment mechanism includes a drive worm gear rotatably mounted on the right side inside the bottom surface of the positioning platform via a bearing, and a drive worm wheel rotatably mounted at the center position inside the bottom surface of the positioning platform via a bearing. Furthermore, a positioning column is fixedly mounted in the center of the top surface inside the positioning platform.

[0011] Preferably, the adjustment mechanism includes a rotating platform, which is rotatably disposed above the interior of the positioning platform, and a spiral guide is fixedly disposed in the center of the top surface of the rotating platform, and the interior of the spiral guide is slidably connected to the bottom end of the guide slider at equal angles.

[0012] Preferably, the adjusting mechanism includes a rotating platform fixedly connected to the top of the drive worm gear shaft, and a guide slide rod is provided above the rotating platform. The guide slide rod slides through the interior of the guide slider, and the inner end of the guide slide rod is fixedly connected to the outer wall of the positioning column, while the outer end of the guide slide rod is fixedly installed on the inner wall of the positioning platform.

[0013] Preferably, the positioning mechanism includes a positioning top cover, which is fixedly installed on the top surface of the positioning platform. The positioning top cover has guide grooves formed at equal angles inside, and the guide grooves slide through the bottom end of the positioning slider. The bottom end of the positioning slider is fixedly connected to the top end of the guide slider.

[0014] Preferably, the positioning mechanism includes a flip-over pressing plate, and the bottom end of the flip-over pressing plate is rotatably mounted on the top end of the positioning slider by a torsion spring, and the outer side of the lower end of the flip-over pressing plate is fixedly connected to the top end of the traction steel cable.

[0015] Preferably, the bottom end of the traction steel cable included in the positioning mechanism is fixedly connected to the outer end of the inner contact arc plate of the positioning slider, and the contact arc plate and the positioning slider are connected to each other by a contact spring. The contact arc plate in contact with the mold is used to drive the flipping pressing plate to flip downward so as to press it onto the top surface of the mold.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This positioning device for mold processing drives the guide slider and the positioning slider to move synchronously through the rotating spiral guide bar inside the support base. After the abutment arc plate moves, it drives the flipping pressure plate to rotate downward, thereby positioning the side wall and top surface of the mold and preventing misalignment during subsequent processing. The specific details are as follows:

[0017] 1. The mold is supported by the positioning top cover. The drive worm inside the rotating support base drives the drive worm wheel on the left side to rotate. At the same time, the drive worm wheel drives the rotating platform and spiral guide bar fixed at the top to rotate synchronously.

[0018] The spiral guide bar drives the internally extending guide slider to move. The guide slider is limited by the through guide rod so that the guide slider slides to the inside along the direction of the guide rod. The guide slider drives the positioning slider fixed at the top to move synchronously so that the positioning slider gradually approaches the outside of the mold to achieve synchronous positioning.

[0019] 2. The positioning slider drives the inner contact arc plate, which is connected by the contact spring, to contact the outer wall of the mold. This causes the contact arc plate to move backward during the contact process, which relaxes the fixed traction steel cable so that the flipping pressing plate can flip downward without being restricted and then press against the top surface of the mold. The positioning slider and the flipping pressing plate achieve the positioning of the side wall and the top surface, preventing offset and misalignment during subsequent processing.

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.

[0028] Please see Figures 1-6 The present invention provides the following technical solution:

[0029] Example 1: To solve the problems existing in the current mold processing process, this example provides a positioning device for mold processing, including a support base 1 and a positioning platform 2 fixedly installed at the center of the top surface of the support base 1; the positioning platform 2 is provided with an adjustment mechanism, and the adjustment mechanism includes a drive worm 3, and a drive worm wheel 4 is engaged in the middle of the inner side of the drive worm 3; the drive worm 3 included in the adjustment mechanism is rotatably disposed on the right side of the bottom surface of the positioning platform 2 through a bearing, and the drive worm wheel 4 is rotatably disposed at the center of the bottom surface of the positioning platform 2 through a bearing, and a positioning column 16 is fixedly disposed in the middle of the top surface inside the positioning platform 2.

[0030] The adjustment mechanism includes a rotating platform 8, which is rotatably positioned above the interior of the positioning platform 2. A spiral guide 7 is fixedly mounted on the center of the top surface of the rotating platform 8, and the spiral guide 7 is slidably connected at equal angles to the bottom end of the guide slider 9. The rotating platform 8 is fixedly connected to the top of the shaft of the drive worm gear 4, and a guide slide rod 10 is mounted above the rotating platform 8. The guide slide rod 10 slides through the interior of the guide slider 9, and the inner end of the guide slide rod 10 is fixedly connected to the outer wall of the positioning column 16. At the same time, the outer end of the guide slide rod 10 is fixedly mounted to the inner wall of the positioning platform 2.

[0031] like Figures 3-5As shown, the mold to be processed is first placed on the top surface of the positioning top cover 11 on the bearing base 1. When positioning according to the mold size, the drive worm 3 inside the bearing base 1 is rotated, which drives the drive worm wheel 4 meshing on the left to rotate. At the same time, the drive worm wheel 4 drives the rotating platform 8 and the spiral guide bar 7 fixedly connected to the top to rotate synchronously.

[0032] The rotating spiral guide bar 7 drives the guide slider 9, which is set at equal angles inside, to move synchronously. At the same time, the guide slider 9 is limited by the guide slide bar 10 that runs through the middle, so that the guide slider 9 slides inward along the direction of the guide slide bar 10, so that the guide slider 9 drives the positioning slider 5, which is fixedly connected to the top, to move synchronously, so that the positioning slider 5 gradually approaches the outside of the mold to achieve synchronous positioning.

[0033] Example 2: To solve the problems existing in the current mold processing, this example adopts the following technical solution: the top surface of the positioning platform 2 is provided with a positioning mechanism, and the positioning mechanism includes a positioning slider 5. The inner side of the positioning slider 5 is slidably provided with an abutment arc plate 6, and the positioning slider 5 is equidistant from the center point of the bearing base 1. The positioning mechanism includes a positioning top cover 11, and the positioning top cover 11 is fixedly installed on the top surface of the positioning platform 2. The interior of the positioning top cover 11 is provided with guide grooves 12 at equal angles, and the interior of the guide grooves 12 slides through the bottom end of the positioning slider 5. The bottom end of the positioning slider 5 is fixedly connected to the top end of the guide slider 9.

[0034] The positioning mechanism includes a flip-over pressing plate 13, the bottom end of which is rotatably mounted on the top of the positioning slider 5 via a torsion spring, and the outer side of the lower end of the flip-over pressing plate 13 is fixedly connected to the top of the traction cable 14; the bottom end of the traction cable 14 included in the positioning mechanism is fixedly connected to the outer end of the inner contact arc plate 6 of the positioning slider 5, and the contact arc plate 6 and the positioning slider 5 are connected to each other via a contact spring 15, and the contact arc plate 6 in contact with the mold is used to drive the flip-over pressing plate 13 to flip downward so as to press it onto the top surface of the mold.

[0035] like Figures 5-6 As shown, the guide slider 9 sliding on the top surface of the positioning top cover 11 drives the positioning slider 5 fixedly connected to the top. The positioning slider 5 drives the inner contact arc plate 6 connected by the contact spring 15 to contact the outer wall of the mold. During the contact process, the contact arc plate 6 moves backward, thereby relaxing the traction steel cable 14 fixedly connected to the outer end. This allows the flipping pressing plate 13 fixedly connected to the traction steel cable 14 to flip downward synchronously after being unrestricted. The flipping pressing plate 13 presses against the top surface of the mold, so that the mold achieves the positioning of the side wall and the top surface through the positioning slider 5 and the flipping pressing plate 13, preventing displacement and misalignment during subsequent processing.

[0036] Although the present invention 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 invention should be included within the protection scope of the present invention.
