Description

Technical Field

[0001] This utility model relates to the field of precision mold technology, and in particular to a fixing component for precision molds. Background Technology

[0002] Precision molds, as core components in modern industrial manufacturing, are characterized by high precision and efficiency, enabling the production of molds with complex geometries, high dimensional accuracy, and high surface quality. With the rapid development of global manufacturing, particularly the continued growth of industries such as automotive, electronics, and home appliances, the demand for precision molds is steadily increasing. In the manufacturing and use of precision molds, fixing components play a crucial role. They not only ensure the stability and accuracy of the mold during processing but also improve production efficiency and reduce production costs. Therefore, it is necessary to design a fixing component for precision molds.

[0003] To address this, patent CN216423285U discloses a precision mold with upper and lower mold fixing components, belonging to the field of mold technology. It includes a base plate, with a lower mold and an upper mold mounted on its upper surface. The upper mold presses against the upper surface of the lower mold. A pressing component is located above the upper mold, and a support component is located on the bottom surface of the base plate. By using the pressing component, during injection molding, the pressure plate is first movably fitted onto the outer surface of the threaded rod through a limiting hole. Then, a threaded collar is fitted onto the outer surface of the threaded rod. Finally, by tightening the threaded collar, the bottom surface of the pressure plate contacts the top surface of the upper mold, stably pressing the upper mold against the top surface of the lower mold. This achieves stable pressing of the lower and upper molds, preventing injection molding failure caused by the lower and upper molds detaching during injection.

[0004] Although the precision mold with upper and lower mold fixing components mentioned above can avoid the problem of the lower mold and upper mold falling off during injection molding, the upper mold is prone to damage and inconvenient to replace during long-term use. Therefore, it is necessary to design a fixing component for precision molds. Utility Model Content

[0005] The purpose of this invention is to provide a fixing component for precision molds, which solves the problem that existing fixing components for precision molds are prone to damage to the upper mold and are inconvenient to replace during long-term use.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a fixing component for precision molds, including a base;

[0007] A lower mold base is fixed to the top of the base, and a support plate is provided above the base;

[0008] The bottom end of the support plate is fixed with a fixing structure;

[0009] The bottom end of the fixed structure is fixed with a disassembly structure, which includes mounting bases uniformly fixed to the bottom end of the fixed structure. Each mounting base has a connecting groove on one side, and each connecting groove has a connecting block inside. One end of each connecting block extends to the outside of the mounting base and is fixed with a connecting plate. Each connecting plate has a fixing bolt threaded inside, and each connecting block has an upper mold fixed on one side.

[0010] Furthermore, guide structures are provided at the corner positions inside the support plate, and a hydraulic rod is fixed to the top of the support plate.

[0011] Furthermore, the guide structure includes an anti-detachment plate, a mounting sleeve, and a guide rod. The mounting sleeve is evenly fixed at the corner positions inside the support plate. The guide rod runs through the interior of each mounting sleeve, and an anti-detachment plate is fixed to the top of each guide rod.

[0012] Furthermore, the guide rod and the mounting sleeve are slidably connected, and the bottom end of the guide rod and the top end of the base are fixedly connected.

[0013] Furthermore, the fixing structure includes a fixing plate, a limiting plate, a limiting pin, a mounting plate, positioning holes, and a positioning shaft. The fixing plate is fixed to the bottom end of the support plate. Positioning holes are evenly provided on both sides of the bottom of the fixing plate. A positioning shaft is provided inside each positioning hole. A mounting plate is fixed to the bottom end of each positioning shaft. Limiting plates are fixed on the outer walls of both sides of the mounting plate. A limiting pin is threaded to the top of each limiting plate.

[0014] Furthermore, the limiting plates are symmetrically distributed on both sides of the mounting plate, one end of each limiting pin extends into the interior of the fixing plate, and the positioning shaft and the fixing plate form a locking structure through positioning holes.

[0015] Furthermore, the connecting blocks are symmetrically distributed on both sides of the upper mold, and the connecting blocks and the mounting base are slidably connected through connecting grooves.

[0016] Furthermore, one end of each fixing bolt extends into the interior of the mounting base.

[0017] The present invention provides a fixing component for precision molds, the advantages of which are:

[0018] With its detachable structure, the connecting block and the upper mold can be easily connected and positioned via the connecting groove and the mounting base through the sliding connection of the connecting block and the mounting base. The limiting effect of the connecting plate makes it easy to control the position and distance of the connecting block during the sliding connection, ensuring that the connecting block can drive the upper mold to the center position when sliding. The fixing bolts can fix the connecting plate and the mounting base to each other, thus enabling the device to facilitate the installation and disassembly of the upper mold and improving the convenience of the fixing components of the precision mold during use.

[0019] With a fixed structure, the installation position of the mounting plate can be easily determined by the positioning connection between the positioning shaft and the fixed plate. The limiting pin can fix the limiting plate and the fixed plate, thus enabling the device to facilitate the overall installation and disassembly of the upper mold base, and improving the convenience of the fixing components of the precision mold during use.

[0020] By incorporating a guide structure, the stability of the support plate during lifting and lowering can be improved through the sliding connection between the mounting sleeve and the guide rod. This ensures the stability of the upper mold during lifting and lowering, enabling the device to guide the equipment and enhancing the stability of the fixing components of the precision mold during use.

[0029] Please see Figures 1-6 The present invention provides a fixing component for precision molds, including a base 1.

[0030] Reference Figure 1 , Figure 2 and Figures 4-6 The base 1 has a lower mold base 2 fixed at its top. A support plate 3 is provided above the base 1. A guide structure 4 is provided at the corner position inside the support plate 3. The guide structure 4 includes an anti-detachment plate 41, an mounting sleeve 42 and a guide rod 43. The mounting sleeve 42 is evenly fixed at the corner position inside the support plate 3. The guide rod 43 passes through the inside of the mounting sleeve 42. The anti-detachment plate 41 is fixed at the top of the guide rod 43. The guide rod 43 and the mounting sleeve 42 are slidably connected. The bottom end of the guide rod 43 is fixedly connected to the top end of the base 1. A hydraulic rod 5 is fixed at the top end of the support plate 3.

[0031] When the hydraulic rod 5 drives the support plate 3 to rise and fall, the support plate 3 will slide and rise and fall on the outside of the guide rod 43 through the mounting sleeve 42. The guide rod 43 is evenly distributed on both sides of the support plate 3, which can improve the stability of the support plate 3 during rising and falling.

[0032] Reference Figures 2-6A fixing structure 6 is fixed to the bottom end of the support plate 3. The fixing structure 6 includes a fixing plate 61, a limiting plate 62, a limiting pin 63, a mounting plate 64, positioning holes 65, and a positioning shaft 66.

Limiting plates 62 are fixed on the outer walls on both sides of the mounting plate 64. The top of each limiting plate 62 is threaded with a limiting pin 63. The limiting plates 62 are symmetrically distributed on both sides of the mounting plate 64. One end of each limiting pin 63 extends into the interior of the fixing plate 61. The positioning shaft 66 and the fixing plate 61 form a locking structure through the positioning holes 65.

[0033] During installation, align the positioning shaft 66 at the top of the mounting plate 64 with the positioning hole 65 so that the positioning shaft 66 enters the interior of the positioning hole 65. At this time, the limiting plate 62 is located on both sides of the fixing plate 61.

Each connecting groove 74 is provided with a connecting block 73. One end of the connecting block 73 extends to the outside of the mounting base 72 and is fixed with a connecting plate 71. Each connecting plate 71 is threaded with a fixing bolt 75. The connecting blocks 73 are symmetrically distributed on both sides of the upper mold 8. The connecting blocks 73 and the mounting base 72 are slidably connected through the connecting grooves 74. One end of each fixing bolt 75 extends into the inside of the mounting base 72. Each side of the connecting block 73 is fixed with the upper mold 8.

[0035] When the upper mold 8 is installed, the openings of the connecting blocks 73 on both sides of the upper mold 8 and the connecting groove 74 at one end are aligned so that the connecting blocks 73 can be inserted into the interior of the connecting groove 74 until one side of the connecting plate 71 and one side of the mounting base 72 abut against each other. Then, the fixing bolt 75 is inserted into the interior of the connecting plate 71 until one end of the fixing bolt 75 extends into the interior of the mounting base 72, so that the connecting plate 71 and the mounting base 72 can be fixedly connected.
