DETAILED DESCRIPTION

[0020] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1

[0022] See also Figure 1-4 , a mold mounting seat for an injection molding machine, comprising a fixed mold mounting seat 1 and a movable mold mounting seat 2 arranged oppositely, the fixed mold mounting seat 1 is used to mount the fixed mold, and the movable mold mounting seat 2 is used to mount the movable mold, and the opposite surfaces of the fixed mold mounting seat 1 and the movable mold mounting seat 2 are provided with four positioning grooves 3; the four positioning grooves 3 of the fixed mold mounting seat 1 are arranged horizontally and in a rectangular arrangement, and the four positioning grooves 3 on the movable mold mounting seat 2 are arranged horizontally and in a rectangular arrangement; the positioning grooves 3 include strip grooves 301 and circular grooves 302 connected to the strip grooves, the circular grooves 302 on both sides of the fixed mold mounting seat 1 are arranged oppositely, and the circular grooves 302 on both sides of the movable mold mounting seat 2 are also arranged oppositely. By arranging positioning grooves on the fixed mold mounting seat and the movable mold mounting seat, and installing a positioning mechanism through the positioning grooves, the position of the positioning mechanism can be adjusted according to the positioning holes on the mold to adapt to different molds. The positioning groove on the movable mold mounting seat 2 is staggered with the positioning groove on the fixed mold mounting seat 1 in the vertical direction. Specifically, the distance between the two vertical positioning grooves on the movable mold mounting seat 2 is smaller than the distance between the two vertical positioning grooves on the fixed mold mounting seat 1.

[0023] Each positioning groove 3 is detachably connected to a positioning mechanism 4 for fixing the mold. Figure 5 As shown, the positioning mechanism 4 includes a screw 401 and a bow-shaped pressure plate 402. A strip hole 403 is provided on the bow-shaped pressure plate 402. The screw 401 passes through the strip hole 403, and the passed end is slidably set in the positioning groove 3. The outer end of the screw 401 is threadedly connected with a nut 404, and the nut 404 is tightly pressed on the bow-shaped pressure plate 402. One end of the bow-shaped pressure plate 402 is provided with a holding portion 405, and the other end is provided with a supporting portion 406. Tighten the nut 404 to make it tightly pressed on the bow-shaped pressure plate 402. At this time, the holding portion 405 is pressed on the outer peripheral edge of the mold, and the supporting portion 405 is supported on the fixed mold mounting seat 1 or the movable mold mounting seat 2.

[0024] The positioning grooves 3 on the fixed mold mounting seat 1 and the movable mold mounting seat 2 are staggered, and the positioning mechanisms 4 on the two mounting seats are staggered, so that the two screws 401 are staggered. When the movable mold mounting seat 2 moves toward the fixed mold mounting seat 1, the screws on the two mounting seats will not abut each other, thereby facilitating the closing of the fixed mold and the movable mold.

[0025] Example 2

[0026] This embodiment differs from Example 1 in that a fixing base 5 is connected to the bottom of the fixed mold mounting base 1, which secures the fixed mold mounting base to the injection molding machine. A material injection port 6 is provided at the center of the fixed mold mounting base 1. The injection tube for injection molding is connected to the material injection port, and raw material is injected into the mold through the material injection port 6. First guide holes 7 are defined at the four corners of the fixed mold mounting base 1, and second guide holes 8 are defined at the four corners of the movable mold mounting base 2. The first guide holes 7 and the second guide holes 8 are slidably connected to guide posts to ensure that the movable mold mounting base 2 maintains linear motion when moving. A U-shaped connecting frame 9 is fixed to the side of the movable mold mounting base 2 away from the fixed mold mounting base. A first connecting hole 10 is provided in the center of the connecting frame 9, and second connecting holes 11 are provided at the upper and lower ends of the connecting frame 9. The movable mold mounting base 2 can be connected to the driving device of the injection molding machine through the first connecting hole 10 and the second connecting hole 11 on the connecting frame 9. The movable mold mounting base 2 is driven to move horizontally by the driving device. The driving device here can be driven by a hydraulic cylinder or by a screw drive. This embodiment will not be described in detail.
