Description

Technical Field

[0001] The utility model relates to the technical field of mold positioning, in particular to a longitudinal positioning device for precision mold manufacturing. Background Art

[0002] Mold manufacturing is an indispensable and important part of industrial production, which involves processing blanks into parts with specific shapes and sizes. In this process, the positioning accuracy of the mold directly affects the quality and precision of the final product.

[0003] Among them, the "longitudinal positioning device for precision mold manufacturing" disclosed by application number "CN216422257U" has solved the various disadvantages that the current positioning device is prone to offset due to vibration during mold manufacturing when positioning the mold, and a large amount of dust generated during mold manufacturing falls into the gap, thereby causing the mold to be not accurately positioned during manufacturing and resulting in the mold being not precise enough. After further searching, it was found that the "mold fixing structure" disclosed by application number "CN210590116U" has effectively solved the problem that in the prior art, the template is fixed on the heating carrier by bolts through a specific technical structure setting. However, due to the different materials of the heating carrier and the mold, the deformation degrees of the two are different during heating due to the thermal expansion and contraction effect, which may cause the bolts to damage the template or the heating carrier and other technical disadvantages. However, in actual use, mold positioning devices with similar structures still have many defects, such as: positioning offset often occurs during the cooperation between the upper mold and the lower mold, resulting in insufficient mold manufacturing accuracy, thereby affecting the accuracy and stability of mold manufacturing. Therefore, it is necessary to design a longitudinal positioning device for precision mold manufacturing to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to provide a longitudinal positioning device for manufacturing precision molds to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a longitudinal positioning device for precision mold manufacturing, comprising a base, a mounting frame and a limit plate, a lower template is fixedly installed on the top of the base, a mounting frame is fixedly installed on the top of the rear end of the lower template, a cam is rotatably installed inside the mounting frame, a lower pressure plate corresponding to the cam is movably installed inside the mounting frame, an upper template is movably installed on the bottom of the lower pressure plate, a limit plate is fixedly installed on the top of the base outside the upper template, mounting sleeves are fixedly installed on both sides of the upper template, a movable rod is movably installed inside the mounting sleeve, a roller is rotatably installed on the outer end of the movable rod, and a movable groove cooperating with the roller is opened inside the limit plate. The roller installed at the outer end of the movable rod slides along the inside of the movable groove, so that the movable rod is squeezed by the movable groove and can shrink along the inside of the mounting sleeve, so that the movable rod squeezes the second spring. At the same time, the sliding block can slide along the inside of the limit groove, so that the upper template and the lower template can be positioned in an orderly manner during the contact process, so that the positioning process between the upper template and the lower template can prevent the occurrence of offset resulting in insufficient mold manufacturing accuracy, thereby increasing the accuracy and stability of mold manufacturing.

[0006] Preferably, a second spring is fixedly mounted on one end of the movable rod, and the other end of the second spring is fixedly connected to the inner wall of the mounting sleeve. After the movable rod is squeezed by the movable groove, the movable rod can shrink along the inside of the mounting sleeve, so that the movable rod squeezes the second spring, and the second spring can easily rebound and buffer.

[0007] Preferably, the movable rod and the mounting sleeve are slidably mounted via a sliding block, and the mounting sleeve is provided with a limiting groove that cooperates with the sliding block. The sliding block can slide along the inside of the limiting groove, so that the upper template and the lower template can be positioned in an orderly manner during the contact process, thereby preventing the upper template and the lower template from being offset during the positioning process, which leads to insufficient mold manufacturing precision.

[0008] Preferably, a sliding rod extending out of the mounting frame is fixedly mounted at the bottom of the lower pressing plate, and a first spring is sleeved on the outside of the sliding rod. The rebound of the first spring can lift and rebound the upper template, so that the upper template is separated from the lower template, and the circulation operation is better performed. At the same time, the activity of the sliding rod can increase the stability effect during the movement of the mounting seat.

[0009] Preferably, the bottom of the lower pressing plate extends to the bottom of the mounting frame, and the bottom end of the lower pressing plate is movably mounted to the upper template via a mounting seat. The upper template and the lower pressing plate can be connected via the mounting seat, and can be further moved when the upper template moves and deviates, thereby preventing interference and engagement.

[0010] Preferably, the base and the mounting frame are fixedly mounted via a mounting frame, and a motor cooperating with the cam is fixedly mounted on one side of the mounting frame. The mounting frame can be supported by the mounting frame and conveniently mounted on the top of the base, and the cam is synchronously driven to rotate inside the mounting frame through the rotation of the motor output end, so that the cam can push the lower pressing plate downward during the rotation process.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] 1. The utility model is provided with a movable rod, a mounting sleeve, a roller and a movable groove. When the upper template and the lower template are docked, the docking may be inaccurate during the downward movement of the upper template. The roller installed at the outer end of the movable rod slides along the inside of the movable groove, so that the movable rod is squeezed by the movable groove and can be contracted along the inside of the mounting sleeve, so that the movable rod presses the second spring. At the same time, the sliding block can slide along the inside of the limiting groove, so that the upper template and the lower template can be positioned in an orderly manner during the contact process, so that the positioning process between the upper template and the lower template can prevent the deviation that causes insufficient mold manufacturing precision, thereby increasing the precision and stability of mold manufacturing.

[0013] 2. The utility model is provided with a sliding rod, a first spring, and the cooperation between the cam and the lower pressure plate. The rotation of the motor output end can synchronously drive the cam to rotate inside the mounting frame, so that the cam can push the lower pressure plate downward during the rotation, so that the upper template and the lower template can be effectively fitted, which is more convenient when fitting the mold. The rebound of the first spring can lift and rebound the upper template, so that the upper template and the lower template are separated. BRIEF DESCRIPTION OF THE DRAWINGS
