Abstract
Description
Technical Field
[0001] The utility model relates to an injection mold, in particular to an injection mold facilitating the replacement of a mold base. Background Art
[0002] An injection mold is a precision tool specifically used for producing plastic products, mainly used in the injection molding process. In this process, molten plastic is injected into the cavity of the mold under high pressure, and after cooling and solidification, it forms the shape of the required plastic product. The design and manufacture of injection molds require a high degree of precision and professionalism because the structure of the mold directly determines the shape, size, and surface quality of the final product.
[0003] Among them, the mold base is an important part of the injection mold. The mold base provides the basic framework and support structure of the injection mold. During the production process of the mold, there are requirements for different molds, so the mold base needs to be continuously replaced to produce different molds. However, due to the relatively traditional fixing method of the existing injection mold, that is, the overall position is fixed by bolts, it is inevitable that the operation will be repeated and cumbersome when replacement and disassembly are required, resulting in inconvenience when replacing the mold base.
[0004] Therefore, in view of the above problems, it is urgent to propose an injection mold facilitating the replacement of the mold base to improve the convenience of replacing the mold base of the injection mold. Summary of the Utility Model
[0005] In order to overcome the above-mentioned shortcomings in the prior art, the utility model provides an injection mold facilitating the replacement of the mold base to improve the convenience of replacing the mold base of the injection mold.
[0006] The technical solution of the utility model is: an injection mold facilitating the replacement of the mold base, including a slide rail, a moving seat, a replacement seat, a threaded rod, a guide rod, and a clamping plate. Two moving seats are slidably arranged on the slide rail, and replacement seats are slidably arranged on both of the two moving seats. Threaded rods are rotatably arranged on the outer sides of the two moving seats, and clamping plates are arranged on the threaded rods in a threaded manner. Moreover, two guide rods are symmetrically arranged front and back on the moving seat, and the two guide rods on the same side penetrate through the adjacent clamping plate, and the clamping plate is slidably matched with the two guide rods on the same side.
[0007] Furthermore, it also includes fixing bolts, and fixing bolts are threadedly penetrated through the front and back sides of the two replacement seats.
[0008] Furthermore, it also includes limiting rods, and limiting rods are arranged on both sides of the moving seat.
[0009] Furthermore, it also includes a pull rod and an elastic member. A pull rod is inserted into one side of each of the two moving seats, an elastic member is arranged between the pull rod and the moving seat, and the pull rod is inserted and matched with the replacement seat through sliding.
[0010] Further, it further includes handles, and handles are provided on both the front and rear sides of the replacement seat.
[0011] Further, it further includes moving wheels, and moving wheels are symmetrically arranged on both sides of the two replacement seats.
[0012] The beneficial effects are as follows: 1. By pushing the position between the moving seat and the replacement seat, the position of the mold blank is adjusted, so as to facilitate replacement during use. At the same time, the mold blank is fixed by the threaded rod and the clamping plate, thereby ensuring the stability after replacement, achieving the effect of facilitating replacement;
[0013] 2. By pulling the pull rod, it can be buckled into one side of the replacement seat at the position to be fixed, so that the whole can obtain a stable use effect during use, thereby improving the stability of use. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The embodiments of the present utility model will be described in detail below with reference to the drawings.
[0020] Embodiment: An injection mold for facilitating the replacement of a mold blank, as Figures 1 - 4As shown, it includes a slide rail 1, a moving seat 2, a replacement seat 3, a threaded rod 4, a guide rod 5, and a clamping plate 6. Two moving seats 2 are slidably arranged on the top of the slide rail 1. The two moving seats 2 can be used to assist in the left and right movement of the mold embryo, so as to achieve position adjustment. On the top of the two moving seats 2, replacement seats 3 are slidably arranged in the front and rear directions. The length of the moving seat 2 is half of that of the replacement seat 3, and the replacement seat 3 has grooves for placing two mold embryos. Threaded rods 4 are longitudinally rotatably arranged on the outer sides of the two moving seats 2. A clamping plate 6 is arranged on the threaded rod 4. The clamping plate 6 can support the upper side of the mold embryo. Two guide rods 5 are symmetrically arranged in the front and rear directions on the moving seat 2. The two guide rods 5 on the same side penetrate through the adjacent clamping plate 6, and the clamping plate 6 is slidably matched with the two guide rods 5 on the same side, which can guide the movement of the clamping plate 6.
[0021] As Figure 1 and Figure 2 shown, it also includes a fixing bolt 7. Fixing bolts 7 are threadedly penetrated through the front and rear sides of the two replacement seats 3. The fixing bolts 7 can fix the position of the mold embryo on the outer side, so as to assist in its overall assembly.
[0022] As Figure 1 and Figure 2 shown, it also includes a limiting rod 8. Limiting rods 8 are arranged on the front and rear sides of the moving seat 2. The ends of the limiting rods 8 are in an extended concave shape, which can firmly support one side of the mold embryo.
[0023] As Figure 1 and Figure 4 shown, it also includes a pull rod 9 and an elastic member 10. A pull rod 9 is inserted into one side of the two moving seats 2. An elastic member 10 is arranged between the pull rod 9 and the moving seat 2. And the pull rod 9 is inserted and matched with the replacement seat 3 through sliding. The pull rod 9 can assist in fixing the position between the moving seat 2 and the replacement seat 3.
[0024] As Figure 1 shown, it also includes a handle 11. Handles 11 are arranged on the front and rear sides of the replacement seat 3 for convenient holding when pushing the device.
[0025] As Figure 1 shown, it also includes moving wheels 12. Moving wheels 12 are symmetrically arranged on the front and rear sides of the two replacement seats 3. The moving wheels 12 can assist in the movement of the replacement seat 3.
[0026] When it is necessary to replace the mold base, the staff can first push the movable seat 2 to move left or right on the slide rail 1 to adjust the overall left and right position, and then hold the handle 11 to push the replacement seat 3 to move forward and backward, so that the two mold bases on it can be adjusted in the front and rear positions. As the replacement seat 3 moves, the moving wheel 12 will assist in pushing the replacement seat 3 to move, and at the same time, the limit rod 8 will also support one side of the mold base to ensure stability during movement. When the replacement seat 3 moves to a suitable position, the pull rod 9 is toggled, and the elastic member 10 is stretched and deformed, and then the pull rod 9 is loosened, and the elastic member 10 is reset, driving the pull rod 9 to clamp into one side of the replacement seat 3, completing the position fixation between the replacement seat 3 and the movable seat 2, and then loosening the fixing bolt 7 so that the mold base to be replaced is not clamped by the fixing bolt 7, and then rotating the threaded rod 4 to make the clamping plate 6 move upward and disengage from the mold base, that is, the mold base can be directly taken out from the movable seat 2 without restriction, and when the replacement is completed, the reverse operation is performed to restore its original position and fixed parts.
[0027] It should be understood that the above description is only for exemplary purposes and is not intended to limit the present invention. Those skilled in the art will understand that variations of the present invention will be included within the scope of the claims herein.
