Description

Technical Field

[0001] This utility model relates to the technical field of mold frame, and in particular to an installation positioning guide device for mold frames. Background Technology

[0002] In industrial production, molds, as important process equipment, are widely used in the manufacture of hardware and plastic products. A mold mainly consists of a mold core and a mold frame. The mold core directly contacts the product, while the mold frame is responsible for installing and fixing the mold core, ensuring its correct relative position during operation and its connection to the machine tool. Traditional mold frames, during installation, make it difficult to center and position the molding cavity on the moving mold frame. This results in lower accuracy when the moving and fixed mold frames close, affecting product quality and production efficiency.

[0003] A related technology, disclosed in CN218838310U, describes a mold frame comprising a fixed template, a movable template, and four guide pillars. The fixed template has symmetrically distributed cavities on both sides of its center line. Each cavity contains a pawl that swings via a pin. The fixed template has a first assembly base on each of its two short axial sides, each with a locking unit of a preset shape that retracts under pressure. The locking unit remains on the first assembly base. The pawl has a second assembly base, with a locking node that allows the locking unit to spring back to its preset shape and engage with it after the locking unit is reached. The locking node communicates with the cavity. This invention addresses the possibility of the locking unit being lost by keeping the locking unit, which restricts the pawl's rotation, on the first assembly base. It is also convenient to use; unlocking is achieved by squeezing and retracting the locking unit, and locking is achieved by releasing and retracting it, making it quick and easy.

[0004] In existing technologies, it is difficult to ensure precise alignment of the molding cavity during mold assembly, especially when installing the moving mold base. This can lead to misalignment when the moving and fixed mold bases are closed, affecting the quality and manufacturing precision of the final product. This is mainly because existing mold bases lack an effective alignment and positioning system in their design. Installation requires careful manual alignment, which is not only difficult to operate but also prone to introducing errors, reducing efficiency and increasing costs. Utility Model Content

[0005] This utility model solves the problems in related technologies and proposes an installation positioning and guiding device for mold frames. The clamping component facilitates the fixing of the end of the forming tube rod, the driving component drives the forming wheel to rotate, and the feeding unit feeds the forming tube rod body, effectively ensuring the efficiency of bending the tube rod body. In addition, the feeding unit achieves the purpose of automatic feeding of the bending forming tube rod through a compact mechanical structure, avoiding the use of electrical equipment and having the characteristics of saving resources.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a mold frame installation positioning guide device, including an upper mold frame, a lower mold frame disposed relative to the upper mold frame, guide bushings respectively disposed at the four peripheral corners of the upper mold frame and the lower mold frame, a cavity seat disposed on the lower end face of the upper mold frame, a mounting seat disposed on the upper end face of the lower mold frame, and a positioning seat disposed on the upper end face of the mounting seat for positioning the cavity seat; The positioning base includes a fixed positioning sleeve fixedly connected to the mounting base, a movable positioning sleeve slidably connected to the fixed positioning sleeve, and a guide component disposed between the fixed positioning sleeve and the movable positioning sleeve; The fixed positioning sleeve and the movable positioning sleeve are coaxially arranged in the cavity seat.

[0007] By adopting the above technical solution, the upper and lower mold sets achieve precise alignment and guidance through guide bushings, ensuring the accuracy of mold assembly. The cavity seat is fixed to the lower end face of the upper mold set to provide cavity support during machining. The mounting seat is fixed to the upper end face of the lower mold set, serving as the base for the positioning seat. Through the cooperation of the fixed and movable positioning sleeves, and with the guidance of the guide components, the positioning seat can be precisely positioned during assembly, thereby ensuring accurate alignment of the upper and lower molds, improving assembly efficiency and machining accuracy.

[0008] As a preferred embodiment, a fixing screw is provided between the mounting base and the fixing positioning sleeve, and the fixing screw passes through the mounting base and the fixing positioning sleeve to connect them.

[0009] By adopting the above technical solution, the function of the fixing screw is to fasten the mounting base and the fixing positioning sleeve to ensure a reliable mechanical connection between the two and prevent loosening or displacement during use.

[0010] As a preferred embodiment, the guide assembly includes guide cones evenly distributed on the upper surface of the movable positioning sleeve, telescopic springs evenly distributed between the fixed positioning sleeve and the movable positioning sleeve, and guide pins fixedly connected to the fixed positioning sleeve and slidably connected to the movable positioning sleeve.

[0011] By adopting the above technical solution, each guide cone is evenly distributed on the upper surface of the movable positioning sleeve, mainly used to guide the cavity seat to move along a preset direction. Telescopic springs are evenly distributed between the fixed positioning sleeve and the movable positioning sleeve, mainly providing elastic support, allowing the movable positioning sleeve to move flexibly while maintaining an appropriate position, preventing damage caused by excessive external force. The guide pin is fixedly connected to the fixed positioning sleeve and slidably connected to the movable positioning sleeve. Its function is to provide a guiding path when the movable positioning sleeve moves, while allowing the movable positioning sleeve to slide freely within a certain range, ensuring smooth movement.

[0012] As a preferred embodiment, each of the guide cones is configured as a right-angled triangle, and the inclination of the hypotenuse of the guide cone in the right-angled triangle increases sequentially with the falling direction of the cavity seat.

[0013] By adopting the above technical solution, the guide cone is designed as a right-angled triangle, with the angle of the hypotenuse gradually increasing downwards to accommodate the falling direction of cavities with different inner diameters. This ensures that the hypotenuse of the guide cone can effectively guide cavities with different inner diameters, enabling each cavity to be accurately aligned and correctly positioned.

[0014] As a preferred embodiment, in order to install the telescopic spring, the fixed positioning sleeve is provided with a first groove, and the movable positioning sleeve is provided with a second groove. The first groove is fixedly connected to one end of the telescopic spring, and the second groove is fixedly connected to the other end of the telescopic spring.

[0015] By adopting the above technical solution, the fixed positioning sleeve and the movable positioning sleeve each have specific functions. The first groove on the fixed positioning sleeve is used to fix one end of the telescopic spring, ensuring the stability of the fixed part; the second groove on the movable positioning sleeve fixes the other end of the telescopic spring, allowing it to telescopically move under specific conditions. The inner diameter of the cavity seat is designed to contact the guide cone block and push the movable positioning sleeve under pressure, thereby causing the telescopic spring to telescopically move.

[0016] As a preferred embodiment, the movable positioning sleeve is provided with a guide hole that matches the guide pin. The guide hole is coaxial with the guide pin, and the depth of the guide hole is 1.2 to 1.5 times that of the guide pin.

[0017] By adopting the above technical solution, the guide hole on the movable positioning sleeve matches the guide pin, ensuring that the movable positioning sleeve can move precisely along the direction of the guide pin. The guide hole on the movable positioning sleeve is designed to be slightly longer than the guide pin, specifically 1.2 to 1.5 times the length of the guide pin. This design effectively limits the range of movement of the movable positioning sleeve, ensuring that it can only move in a specific direction, thereby avoiding misoperation and unintended movement. The guide pin passes through the guide hole, and the two are coaxially set, ensuring a precise guiding effect.

[0018] Compared with the prior art, the beneficial effects of this utility model are: This utility model; The upper mold base and the lower mold base are precisely aligned and guided by guide bushings to ensure the accuracy of mold assembly. The cavity seat is fixed on the lower end face of the upper mold base to provide cavity support during processing.
