Description

Technical Field

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

[0002] In industrial production, molds and tools are used to obtain the desired products through injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. Molds are tools used to make shaped items, and market demand is generally focused on optimizing how to clamp and facilitate user use.

[0003] According to a positioning fixture for mold processing disclosed in the above application (Announcement No.: CN210731674U), the circular rotating handle rotates at the same time, driving the extrusion threaded rod to rotate, thereby pushing the extrusion block to extrude the mold to be processed. At the same time, a slider is fixedly connected to the bottom of the extrusion block to cooperate with the groove opened on the top of the U-shaped fixed block.

[0004] However, in actual use, the mold is usually placed on the mounting platform. The clamping block is driven by the telescopic cylinder to move the mold towards the vertical plate and then clamp it. During the movement, the mold is prone to displacement on the surface of the mounting platform due to different shapes, which leads to unstable clamping effect. In view of this, we propose a positioning fixture for mold processing. Utility Model Content

[0005] The purpose of this utility model is to provide a positioning fixture for mold processing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning fixture for mold processing, comprising a fixed platform, a vertical plate fixed to the surface of the fixed platform, an mounting block fixedly mounted on the upper surface of the fixed platform, a telescopic cylinder fixedly mounted on the surface of the mounting block, a clamping block fixedly mounted on the movable end of the telescopic cylinder, a stabilizing mechanism provided on the surface of the clamping block, and a promoting mechanism provided on the surface of the clamping block, the stabilizing mechanism comprising:

[0007] A bending groove is formed on the surface of the clamping block. A bending rod is fixedly installed on the inner wall of the bending groove. A bending spring is fixedly installed on the inner wall of the bending groove. A bending cylinder is fixedly connected to the end of the bending spring away from the inner wall of the bending groove. An extrusion plate is fixedly connected to the end of the bending cylinder away from the bending spring.

[0008] A round rod is fixedly connected to the surface of the clamping block. A limit block is fixedly installed on the surface of the extrusion plate. A positioning block is fixedly installed on the surface of the clamping block. An arc-shaped groove is formed on the surface of the bending cylinder.

[0009] Preferably, the promoting mechanism includes a promoting groove, which is formed on the surface of the extrusion plate. A straight rod is fixedly connected to the inner wall of the promoting groove. One end of a torsion spring is fixedly connected to the arc surface of the straight rod. The end of the torsion spring away from the straight rod is fixedly connected to the inner wall of the clamping plate. A rubber strip is fixedly installed on the surface of the clamping plate.

[0010] Preferably, the surface of the clamping plate is provided with a rotating hole, the diameter of which is adapted to the diameter of the straight rod, and the clamping plate is sleeved on the arc surface of the straight rod so that the clamping plate can rotate on the arc surface of the straight rod.

[0011] Preferably, the surface of the clamping block is provided with an installation groove, the shape of which is adapted to the shape of the extrusion plate, so that the extrusion plate can be completely housed inside the installation groove after being subjected to force.

[0012] Preferably, the surface of the extrusion plate is provided with a movable hole, the shape of which is adapted to the shape of the round rod, and the extrusion plate is sleeved on the surface of the round rod so that the extrusion plate can rotate on the arc surface of the round rod.

[0013] Preferably, the shape of the bending groove is adapted to the shape of the bending cylinder, so that the bending cylinder can move inside the bending groove.

[0014] Preferably, the shape of the arc-shaped groove is adapted to the shape of the curved rod, so that the curved rod can move inside the arc-shaped groove.

[0015] Compared with the prior art, this utility model provides a positioning fixture for mold processing, which has the following beneficial effects:

[0016] 1. The positioning fixture for this mold processing is equipped with a stabilizing mechanism. Under the action of the bending spring, the bending cylinder drives the extrusion plate to unfold outward of the clamping block. The unfolding angle of the extrusion plate is limited by the action of the limiting block and the positioning block, thus the extrusion plate clamps the surface of the mold. During the movement of the clamping block under the influence of the telescopic cylinder, the two extrusion plates limit and clamp the surface of the mold. As the telescopic cylinder moves, one end of the mold contacts the vertical plate, causing the extrusion plate to rotate around the round rod. The bending cylinder moves along the bending rod and compresses the bending spring, which has a buffering effect on the clamping of the mold surface by the clamping block, and has a better positioning and clamping protection effect for the mold.

[0017] 2. The positioning fixture for this mold processing is equipped with a facilitating mechanism. Under the action of the torsion spring, the clamping plate adaptively conforms to the surface of the mold. The V-shape of the clamping plate provides better clamping effect on the mold surface. Combined with the friction of the rubber strip, the clamping effect on the mold is more stable, ensuring the stability of the mold position during movement and guaranteeing the stability of the subsequent positioning position.

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: a positioning fixture for mold processing, including a fixed platform 1, a vertical plate 2 fixed on the surface of the fixed platform 1, an mounting block 5 fixedly installed on the upper surface of the fixed platform 1, a telescopic cylinder 6 fixedly installed on the surface of the mounting block 5, a clamping block 7 fixedly installed on the movable end of the telescopic cylinder 6, a stabilizing mechanism 3 provided on the surface of the clamping block 7, and a promoting mechanism 4 provided on the surface of the clamping block 7. The stabilizing mechanism 3 includes a bending groove 301, a bending rod 302, a bending spring 303, a bending cylinder 304, an arc groove 305, a round rod 306, a pressing plate 307, a limiting block 308, and a positioning block 309.

[0024] In one embodiment of this utility model, a bending groove 301 is formed on the surface of the clamping block 7, a bending rod 302 is fixedly installed on the inner wall of the bending groove 301, a bending spring 303 is fixedly installed on the inner wall of the bending groove 301, a bending cylinder 304 is fixedly connected to one end of the bending spring 303 away from the inner wall of the bending groove 301, a pressing plate 307 is fixedly connected to one end of the bending cylinder 304 away from the bending spring 303, a round rod 306 is fixedly connected to the surface of the clamping block 7, a limit block 308 is fixedly installed on the surface of the pressing plate 307, a positioning block 309 is fixedly installed on the surface of the clamping block 7, and an arc groove 305 is formed on the surface of the bending cylinder 304.

[0025] In addition, the promoting mechanism 4 includes a promoting groove 401, which is formed on the surface of the extrusion plate 307. A straight rod 402 is fixedly connected to the inner wall of the promoting groove 401. One end of a torsion spring 403 is fixedly connected to the arc surface of the straight rod 402. The end of the torsion spring 403 away from the straight rod 402 is fixedly connected to the inner wall of the clamping plate 404. A rubber strip 405 is fixedly installed on the surface of the clamping plate 404. A rotating hole is formed on the surface of the clamping plate 404. The diameter of the rotating hole is adapted to the diameter of the straight rod 402. The clamping plate 404 is sleeved on the arc surface of the straight rod 402, so that the clamping plate 404 can rotate on the arc surface of the straight rod 402.

[0026] In this embodiment of the invention, the surface of the clamping block 7 is provided with a mounting groove, the shape of which is adapted to the shape of the extrusion plate 307, so that the extrusion plate 307 can be completely housed inside the mounting groove after being subjected to force. As the telescopic cylinder 6 moves, the extrusion plate 307 will eventually be housed inside the mounting groove. The positioning block 309 is installed inside the mounting groove. The limiting block 308 fixed on the surface of the extrusion plate 307, together with the positioning block 309, has a limiting effect on the rotation angle of the extrusion plate 307. The number of extrusion plates 307 is provided in two sets, and the two sets of extrusion plates 307 are arranged in a mirror image on the surface of the clamping block 7. At both ends, a limiting effect is ensured on the mold surface to prevent displacement during mold movement. The surface of the extrusion plate 307 is provided with movable holes, the shape of which is adapted to the shape of the round rod 306. The extrusion plate 307 is sleeved on the surface of the round rod 306, allowing the extrusion plate 307 to rotate on the arc surface of the round rod 306. The shape of the bending groove 301 is adapted to the shape of the bending cylinder 304, allowing the bending cylinder 304 to move inside the bending groove 301. The shape of the arc groove 305 is adapted to the shape of the bending rod 302, allowing the bending rod 302 to move inside the arc groove 305.

[0027] In this invention, during use, the bending cylinder 304, under the action of the bending spring 303, drives the extrusion plate 307 to unfold outward of the clamping block 7. Under the action of the limiting block 308 and the positioning block 309, the unfolding angle of the extrusion plate 307 is limited, thereby the extrusion plate 307 has a clamping effect on the surface of the mold. During the process of the clamping block 7 moving under the influence of the telescopic cylinder 6, the two extrusion plates 307 have a limiting clamping effect on the surface of the mold. As the telescopic cylinder 6 moves, one end of the mold contacts the vertical plate 2, causing the extrusion plate 307 to rotate around the round rod 306. The bending cylinder 304 moves along the bending rod 302 to compress the bending spring 303, which has a buffering effect on the clamping of the mold surface by the clamping block 7, and has a better positioning and clamping protection effect on the mold.

[0028] Furthermore, under the action of the torsion spring 403, the clamping plate 404 adaptively conforms to the surface of the mold. The V-shape of the clamping plate 404 provides better clamping effect on the surface of the mold. Combined with the friction of the rubber strip 405, the clamping effect on the mold is more stable, ensuring the stability of the mold position during movement and ensuring the stability of the subsequent positioning position.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
