[0001] This utility model relates to the field of positioning technology in die casting processing, and specifically to a positioning device for die casting of parts. Background Technology

[0002] Molds are various molds and tools used in industrial production to obtain the desired products through injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. They mainly achieve the processing of the shape of the object by changing the physical state of the material being molded. In die casting molds, the parts are tightly attached to the inner wall of the mold during die casting.

[0003] A search of existing technology revealed a device for positioning die-casting parts, with publication number CN214922373U. This device uses an elastic tapered pin to achieve precise positioning, thereby increasing the positioning accuracy and improving the processing efficiency. However, during long-term positioning and guiding, the guiding components are prone to wear, which can lead to poor positioning and affect the accuracy of workpiece processing.

[0004] Based on this, the present invention designs a positioning device for die casting of parts to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a positioning device for die casting of parts.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A positioning device for die casting of parts includes a die casting machine housing. Two electric push rods are fixedly connected to the inner wall of the die casting machine housing. A die casting mold is disposed between the two electric push rods. The device also includes a positioning mechanism installed inside the die casting machine housing. The surface of the positioning mechanism is connected to the telescopic end of the electric push rods. The positioning mechanism includes a mold frame installed on the surface of the die casting mold. A positioning component is disposed at the upper end of the mold frame. The positioning component is located above the electric push rods and connected to the inner wall of the die casting machine housing. A support component is connected to the lower end of the mold frame. The support component is installed on the inner bottom wall of the die casting machine housing.

[0008] Furthermore, the positioning component includes an upper connecting block fixedly connected to the upper end of the mold frame. The upper connecting block has two internal positioning holes that extend to the outside of the upper connecting block. A one-way bearing is fixedly connected to the inner wall of the internal positioning hole. A sliding rod is provided inside the one-way bearing. Both ends of the sliding rod are rotatably connected to the inner wall of the die-casting machine housing.

[0009] Furthermore, the supporting assembly includes a lower connecting block fixedly connected to the lower end of the mold frame and a supporting slide rail fixedly connected to the inner wall of the die casting machine housing. The lower end of the lower connecting block is provided with a slide groove, and a guide shoe is fixedly connected to the inner wall of the slide groove. The inner wall of the guide shoe is slidably connected to the surface of the supporting slide rail. The lower end of the supporting slide rail is fixedly connected to an upper connecting frame, and the surface of the upper connecting frame is slidably connected to a lower connecting frame.

[0010] Furthermore, a threaded tube is fixedly connected to the inner wall of the upper connecting frame, and a sliding strip is fixedly connected to the surface of the upper connecting frame away from the threaded tube.

[0011] Furthermore, the lower connecting frame is fixedly connected to the inner bottom wall of the die-casting machine housing, and a locking disc is rotatably connected to the inner wall of the lower connecting frame, with a threaded rod fixedly connected to the inner wall of the locking disc.

[0012] Furthermore, the inner wall of the lower connecting frame is provided with a sliding groove, and the sliding strip is slidably connected to the inner wall of the sliding groove.

[0013] Furthermore, the upper end of the threaded rod extends into the interior of the threaded tube, and the surface of the threaded rod is threadedly connected to the inner wall of the threaded tube.

[0014] Furthermore, one end of the sliding rod is fixedly connected to a pulley, and a transmission belt is fitted onto the surface of the two pulleys.

[0015] Furthermore, the longitudinal cross-section of the sliding rod is polygonal, and the surface of the sliding rod is slidably connected to the inner wall of the sliding sleeve.

[0016] Furthermore, a sliding sleeve is fixedly connected to the inner edge of the one-way bearing, and the inner wall cross-section of the sliding sleeve matches the sliding rod.

[0017] Beneficial effects

[0018] The positioning device for die casting of the above-mentioned parts uses a positioning component to move the mold frame and the upper connecting block along with the die casting mold, ensuring the positioning effect of the die casting mold. Due to the opening of the internal positioning hole, the one-way bearing moves synchronously with the upper connecting block. The sliding sleeve slides on the surface of the sliding rod. The operator can manually turn the transmission belt to drive the adjacent sliding rod to rotate synchronously through two pulleys, so that the contact force surface between the sliding rod and the sliding sleeve changes, reducing wear caused by long-term movement, ensuring the positioning and alignment effect of the mold, and improving the accuracy of workpiece processing.

[0019] The device supports the lower connecting block through a support slide rail, ensuring good support for the mold frame and alleviating the large friction caused by the positioning component during positioning and guidance. The guide shoe inside the slide groove contacts the support slide rail. The guide shoe is made of plastic, which protects the metal parts from easy wear and deformation, ensuring the positioning accuracy during the die casting process. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-5 A positioning device for die casting of parts includes a die casting machine housing 1, with two electric push rods 2 fixedly connected to the inner wall of the die casting machine housing 1, and a die casting mold disposed between the two electric push rods 2.
