[0022] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The precision mold frame with positioning mechanism is a device specially designed to ensure the mold is accurately aligned and fixed on the working equipment. The precision mold frame plays a very important role in the mold industry. It is the basic structure of the mold, ensuring that the mold can be accurately positioned and work stably. The precision mold structure is complex, the manufacturing technology requirements are high, and the corresponding cost is also relatively high. Therefore, the design and manufacture of precision mold frames require a high level of technology and cost investment. Precision mold frames are an indispensable part of the mold manufacturing industry. Its design and manufacture directly affect the performance of the mold and the quality of the final product; please refer to the details. Figure 1-Figure 6 As shown, the present embodiment provides a precision mold frame with a positioning mechanism, including a mold frame main body 1. When the precision mold frame is used, the fitting clearance between the guide pillar 2 and the mold frame is improper, severe friction may occur, and the guide pillar 2 is inconvenient to be taken out and replaced in time, and the practicality is low. Therefore, the specific details are as follows: a positioner 3 is fixedly connected to the outer wall of the mold frame main body 1, and four guide pillars 2 are symmetrically sleeved in the cavity of the mold frame main body 1. A cavity is provided inside the guide pillar 2, and two distance adjusting plates 21 are symmetrically sleeved on the outer wall of the guide pillar 2. The distance adjusting plate 21 is an arc-shaped one that fits the outer wall of the guide pillar 2. The outer wall of the distance adjusting plate 21 also fits the inner wall of the mold base hole of the mold frame main body 1. The outer wall of the distance adjusting plate 21 is fixedly connected to a distance adjusting component 22 for driving the distance adjusting plate 21 to gather and spread, so as to adjust the distance between the distance adjusting plate 21 and the mold frame main body 1, stabilize the position of the guide pillar 2 and the mold frame main body 1, prevent displacement, realize free removal of the guide pillar 2, avoid severe friction caused by improper fitting clearance between the guide pillar 2 and the mold frame main body 1, and improve practicality.

[0024] Among them, the mold frame body 1 is a device specially designed to ensure that the mold is accurately positioned and fixed on the working equipment. The mold frame is the supporting part of the entire mold core, and together with the mold cavity, mold core, pressure plate, positioning column, etc., it constitutes the basic structure of the mold. It realizes high-precision positioning and efficient production of the mold through the coordinated work of multiple components such as fixing devices, adjustment devices, and guide mechanisms. This is common knowledge among people in this technical field and will not be elaborated here.

[0025] The specific structure of the distance adjusting component 22 is disclosed to achieve the effect of the distance adjusting component 22 on adjusting the distance between the guide column 2 and the mold frame body 1. The distance adjusting component 22 includes a bearing 221, wherein the end of the bearing 221 is rotatably connected to the inner wall of the guide column 2, and the outer wall of the bearing 221 is fixedly connected with a gear 222, and the outer wall of the gear 222 is meshed with a rack 223. By rotating the bearing 221, the gear 222 is driven to rotate on the outer wall of the rack 223, and the distance of the distance adjusting plate 21 at the end of the rack 223 is adjusted to improve work efficiency.

[0026] Taking into account the lack of precision when installing the guide column 2 into the mold base hole, the upper end of the distance adjustment plate 21 is fixedly connected to the rotating shaft 25, and the inner wall of the rotating shaft 25 is rotatably connected to the introduction plate 26. The introduction plate 26 is inclined from top to bottom, which is convenient for the user to freely adjust the angle of the introduction plate 26 and more accurately insert the guide column 2 into the mold base hole of the mold frame main body 1.

[0027] The rack 223 needs to have a support point on the inner wall of the guide column 2 in order to better cooperate with the gear 222. An open slide groove 23 is provided on the inner wall of the guide column 2. The open slide groove 23 is slidably adapted to the rack 223 to reinforce the distance adjustment component 22 as a whole. A twisting block 24 is fixedly connected to the upper end of the bearing 221. The twisting block 24 is a polyhedron, which is convenient for the user to directly turn the twisting block 24 by hand to adjust the distance between the distance adjustment plate 21 and the mold frame body 1.

[0028] The improvement of this embodiment is that:

[0029] The distance between the distance adjusting plate 21 and the mold frame body 1 is adjusted by the distance adjusting component 22 to avoid severe friction caused by improper matching clearance between the guide column 2 and the mold frame body 1, so as to facilitate timely removal and replacement of the mold frame. The guide plate 26 can freely adjust the angle, so that the guide column 2 can be more accurate when installed on the inner wall of the mold frame body 1, and reduce wear. The outer wall of the mold frame body 1 is fixedly connected with a positioner 3, and four guide columns 2 are symmetrically sleeved in the cavity of the mold frame body 1. A cavity is provided inside the guide column 2, and two distance adjusting plates 21 are symmetrically sleeved on the outer wall of the guide column 2. The distance adjusting plate 21 is an arc-shaped one that fits the outer wall of the guide column 2. The outer wall of the distance adjusting plate 21 also fits the inner wall of the mold base hole of the mold frame body 1. The outer wall of the distance adjusting plate 21 is fixedly connected with a distance adjusting component 22. By adjusting the distance between the distance adjusting plate 21 and the mold frame body 1, the position of the guide column 2 and the mold frame body 1 is stabilized to prevent displacement, so as to realize free removal of the guide column 2, avoid severe friction caused by improper matching clearance between the guide column 2 and the mold frame body 1, and improve practicality.

[0030] Taking into account that the distance adjustment method still has limitations, the distance adjustment component 22 includes a bearing 221, the end of the bearing 221 is rotatably connected to the inner wall of the guide column 2, the outer wall of the bearing 221 is fixedly connected to a gear 222, and the outer wall of the gear 222 is meshed with a rack 223. By rotating the bearing 221, the gear 222 is driven to rotate on the outer wall of the rack 223, and the distance of the distance adjustment plate 21 at the end of the rack 223 is adjusted to improve work efficiency.

[0031] Taking into account that the guide column 2 is not installed accurately into the mold base hole, it is easy to increase friction and wear between the guide column 2 and the mold frame body 1 during installation. The upper end of the spacing plate 21 is fixedly connected to the rotating shaft 25, and the inner wall of the rotating shaft 25 is rotatably connected to the introduction plate 26. The introduction plate 26 is inclined from top to bottom, which is convenient for the user to freely adjust the angle of the introduction plate 26 and more accurately insert the guide column 2 into the mold base hole of the mold frame body 1.

[0032] Considering that the rack 223 needs a support point on the inner wall of the guide column 2 to better cooperate with the gear 222, an open slide groove 23 is opened on the inner wall of the guide column 2, and the open slide groove 23 is slidably adapted to the rack 223. Through the cooperation between the open slide groove 23 and the rack 223, the rack 223 is firmly slid inside the guide column 2.

[0033] In order to better adjust the distance between the distance adjustment plate 21, a twisting block 24 is fixedly connected to the upper end of the bearing 221. The twisting block 24 is a polyhedron, which is convenient for the user to directly rotate the twisting block 24 by hand to adjust the distance between the distance adjustment plate 21 and the mold frame body 1.

[0034] In summary, the working principle of this scheme is as follows:

[0035] When the precision mold frame with a positioning mechanism of the utility model is used, the introduction plate 26 is first rotated on the rotating shaft 25 and adjusted to a suitable angle, the mold frame body 1 to be used is prepared, the mold base hole on the mold frame body 1 is aligned with the end of the introduction plate 26 and inserted, and after reaching a suitable distance, the user manually twists the twisting block 24, and the twisting block 24 will drive the bearing 221 below to rotate inside the guide column 2. At the same time, the bearing 221 drives the gear 222 on the outer wall to rotate, and the gear 222 engages the transmission rack 223, driving the rack 223 to slide on the inner wall of the open slide groove 23. When the distance adjustment plate 21 fixedly connected to the end of the rack 223 is tightly fitted to the inner wall of the mold frame body 1, the twisting block 24 can no longer be twisted, and the four guide columns 2 are installed in the mold base holes inside the mold frame body 1 in sequence, and the introduction plate 26 is rotated again, and the introduction plate 26 is rotated to the outer wall to fit the surface of the mold frame body 1, so as to further enhance the overall stability of the guide column 2.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
