Description

Technical Field

[0001] The utility model belongs to the technical field of mold accessories, and particularly relates to an insert positioning device. Background Art

[0002] When forming a product, the mold usually adds an insert. The mold insert plays a role in positioning and supporting the product during the manufacturing process. By using mold inserts, the position of the mold can be fixed to ensure the accuracy and stability of the product position during the processing. The existing patent document with publication number CN102294794A discloses a die-casting mold insert positioning device, which includes a positioning column, a limit sleeve, a spring, a fastening screw, and a travel switch. The positioning hole on the side of the metal insert is supported and positioned by the positioning column on the mold; the middle part of the positioning column is provided with a spring and a limit sleeve, which is fixed with a fastening screw and connected to the travel switch. The existing disclosed mold insert is directly installed inside the mold, which is not convenient to install and consumes more mold materials. At the same time, the existing die-casting mold insert positioning device only positions the mold insert in a single axial direction through the positioning column, and the positioning effect is poor. Therefore, it is necessary to design an insert positioning device. Summary of the Invention

[0004] The invention objective of the utility model is achieved through the following technical solutions: a tool positioning device, comprising a movable mold frame, a movable mold core detachably connected to the movable mold frame is provided in the movable mold frame, and a side slider slidably connected to the movable mold core is provided on the movable mold core; a vertical tube detachably connected to the movable mold core is also provided on the movable mold core, one end of the vertical tube abuts against the side slider, and the other end of the vertical tube extends along the movable mold core toward the movable mold frame; a fixing mechanism for positioning the vertical tube is provided on the movable mold frame, and the fixing mechanism includes a base body, and a positioning pin that can elastically move relative to the vertical tube is provided in the base body.

[0005] Preferably, the movable mold core is provided with a first groove for accommodating the side slider, the outer contour of the first groove being compatible with the outer contour of the side slider; a vertical tube is provided on the end of the movable mold core facing the fixing mechanism, the vertical tube passing through the movable mold core and extending toward the fixing mechanism on the movable mold frame. The provision of the first groove facilitates the installation of the side slider.

[0006] Preferably, a first step is provided on the side slider, and an annular outer protrusion is provided at the end of the vertical pipe, and the annular outer protrusion rests on the first step.

[0007] Preferably, a columnar protrusion is provided on the first step, and the columnar protrusion extends into the vertical tube; the vertical tube is in the shape of a hollow cylinder, and the outer contour of the columnar protrusion and the inner contour of the vertical tube are adapted to each other.

[0008] By providing the first step, it is convenient to limit the end of the vertical pipe; the outer contour of the columnar protrusion and the inner contour of the vertical pipe are adapted to each other, so that the vertical pipe can be stably pressed against the side slider.

[0009] Preferably, the side slider is provided with a strip groove for mounting the vertical pipe, and the outer contour of the strip groove and the outer contour of the vertical pipe are adapted to each other. By providing the strip groove, it is convenient to limit the vertical pipe.

[0010] Preferably, the movable mold frame is provided with a second groove for mounting the base body, and when the base body is placed in the second groove, the upper end surface of the base body and the upper end surface of the movable mold frame are arranged flush with each other; the fixing mechanism also includes an adjusting bolt and an elastic member, and the positioning pin, adjusting bolt and elastic member are all arranged in pairs.

[0011] Preferably, the base body is provided with a mounting channel and a mounting hole, and the mounting hole and the mounting channel are connected to each other; a second step is provided on the mounting channel, and the positioning pin rests on the second step and passes through the mounting hole; an adjusting bolt is provided in the mounting channel and is threadedly connected to it, and an elastic member is provided between the adjusting bolt and the positioning pin.

[0012] Preferably, the mounting channel and the mounting hole are coaxially arranged, and the inner diameter of the mounting hole is smaller than the inner diameter of the mounting channel; a limiting protrusion is provided on the positioning pin, and when the limiting protrusion abuts on the second step, the end of the positioning pin passes through the mounting hole; one end of the elastic member abuts on the limiting protrusion, and the other end of the elastic member abuts on the adjusting bolt.

[0014] In the default state, the limiting protrusion abuts the second step, and the end of the locating pin protrudes from the mounting hole. At this point, the elastic member is in a compressed state. When the riser is placed on the base body, the outer wall of the riser compresses the end of the locating pin, causing it to retract into the mounting hole. Because the elastic member constantly abuts the locating pin, the end of the locating pin abuts the outer wall of the riser, thereby limiting the position of the riser. When the riser is placed on the base body, it is clamped between the two first protrusions, which also limit the position of the riser. Simultaneously, the end of the riser abuts the second protrusion, which also limits the position of the riser. The interaction between the first and second protrusions and the locating pin improves the positioning of the riser. The riser here represents the insert in the prior art. The second step prevents the locating pin from falling out of the mounting hole. The adjustment screw facilitates adjustment of the elastic modulus of the elastic member, thereby adjusting the degree of compression on the riser.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The vertical tube of the present invention is arranged between the side slider and the fixing mechanism, and the vertical tube is arranged outside the movable mold core, so that the movable mold core requires less material, which greatly reduces the mold production cost; 2. The vertical tube and the movable mold core are detachably connected, and disassembly and assembly are convenient; 3. The vertical tube is fixed by the positioning pins on the fixing mechanism and the base body, and the fixing effect is good and reliable. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0023] like Figures 1 to 5 As shown, this embodiment discloses an insert positioning device, including a movable mold frame 1, in which a movable mold core 2 detachably connected to the movable mold frame 1 is provided, and a side slider 3 slidably connected to the movable mold core 2 is provided on the movable mold core 2; the movable mold core 2 is also provided with a vertical tube 4 detachably connected to the movable mold core 2, one end of the vertical tube 4 abuts against the side slider 3, and the other end of the vertical tube 4 extends along the movable mold core 2 toward the movable mold frame 1; the movable mold frame 1 is provided with a fixing mechanism 5 for positioning the vertical tube 4, and the fixing mechanism 5 includes a base body 51, and a positioning pin 52 that can elastically move relative to the vertical tube 4 is provided in the base body 51.

[0024] The movable mold core 2 is provided with a first groove 6 for placing the side slider 3, and the outer contour of the first groove 6 is adapted to the outer contour of the side slider 3; the movable mold core 2 is provided with a vertical tube 4 at the end facing the fixing mechanism 5, and the vertical tube 4 passes through the movable mold core 2 and extends toward the fixing mechanism 5 on the movable mold frame 1. The side slider 3 is provided with a first step 7, and the end of the vertical tube 4 is provided with an annular outer protrusion 41, and the annular outer protrusion 41 abuts against the first step 7. The first step 7 is provided with a columnar protrusion 8, and the columnar protrusion 8 extends into the vertical tube 4; the vertical tube 4 is a hollow cylindrical shape, and the outer contour of the columnar protrusion 8 is adapted to the inner contour of the vertical tube 4. The side slider 3 is provided with a strip groove 10 for mounting the vertical tube 4, and the outer contour of the strip groove 10 is adapted to the outer contour of the vertical tube 4.

[0025] The movable mold frame 1 is provided with a second groove 11 for mounting the base body 51. When the base body 51 is placed in the second groove 11, the upper end surface of the base body 51 and the upper end surface of the movable mold frame 1 are flush with each other. The fixing mechanism 5 also includes an adjusting bolt 53 and an elastic member 54. The positioning pin 52, the adjusting bolt 53, and the elastic member 54 are all arranged in pairs. The base body 51 is provided with a mounting channel 55 and a mounting hole 56. The mounting hole 56 and the mounting channel 55 are interconnected. The mounting channel 55 is provided with a second step 57. The positioning pin 52 rests on the second step 57 and extends through the mounting hole 56. The mounting channel 55 is provided with an adjusting bolt 53 threadedly connected thereto. An elastic member 54 is provided between the adjusting bolt 53 and the positioning pin 52. The mounting channel 55 and the mounting hole 56 are coaxially arranged, and the inner diameter of the mounting hole 56 is smaller than that of the mounting channel 55. The positioning pin 52 is provided with a limiting protrusion 58. When the limiting protrusion 58 abuts the second step 57, the distal end of the positioning pin 52 passes through the mounting hole 56. One end of the elastic member 54 abuts the limiting protrusion 58, and the other end of the elastic member 54 abuts the adjusting bolt 53. The upper end surface of the base body 51 is provided with a pair of first protrusions 59. The mounting channel 55 and the mounting hole 56 are provided on the first protrusions 59. The mounting channel 55 and the mounting hole 56 are arranged toward the vertical tube 4. The base body 51 is also provided with a second protrusion 510, which is arranged perpendicular to the first protrusion 59. The distal end of the vertical tube 4 abuts the second protrusion 510.

[0026] The specific operation process of this embodiment is as follows: install the fixing mechanism 5 on the movable mold frame 1, and install the vertical tube 4 on the fixing mechanism 5; then push the side slider 3 toward the fixing mechanism 5 so that the side slider 3 rests on the end of the vertical tube 4.

[0027] In the default state, the limiting protrusion 58 abuts against the second step 57, and the end of the locating pin 52 extends through the mounting hole 56. At this time, the elastic member 54 is in a compressed state. When the vertical tube 4 is placed on the base body 51, the outer wall of the vertical tube 4 presses against the end of the locating pin 52, causing the locating pin 52 to retract into the mounting hole 56. Because the elastic member 54 always abuts against the locating pin 52, the end of the locating pin 52 abuts against the outer wall of the vertical tube 4, thereby limiting the position of the vertical tube 4. When the vertical tube 4 is placed on the base body 51, the vertical tube 4 is clamped between the two first protrusions 59, so that the first protrusion 59 also limits the position of the vertical tube 4. At the same time, the end of the vertical tube 4 abuts against the second protrusion 510, so that the second protrusion 510 also limits the position of the vertical tube 4. The first protrusion 59, the second protrusion 510 and the positioning pin 52 cooperate with each other to better position the vertical tube 4. The vertical tube 4 here is an insert in the prior art. The adjustment bolt 53 is provided to facilitate adjustment of the elastic coefficient of the elastic member 54, thereby adjusting the degree of compression on the vertical tube 4.

[0028] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
