[0015] The technical effects achieved by this utility model are as follows:

[0016] This utility model relates to a deep-hole plate injection mold assembly. By observing the bubble level, when the bubble is not centered, a servo motor can be activated to drive the reciprocating screw to rotate, causing the ball nut assembly and the fixing sleeve to move back and forth. Through the connection of the support frame, the support plate at the top of the support frame can be easily offset at an angle until the bubble is centered. At this point, the support plate is in a horizontal state, allowing the injection mold body to open and close in a horizontal state. This solves the problem of the lack of an angle adjustment mechanism at the bottom, which easily leads to lateral forces and thus aggravates the wear of the guide components.

[0017] This utility model relates to a deep-hole plate injection mold assembly. By pressing the insert plates on both sides and squeezing the return spring, the insert plates on both sides can be easily removed from the positioning steel plate, thus facilitating the removal of the positioning steel plate from the bottom of the injection mold body.

The return spring is then released, and the return effect of the return spring allows the insert plates on both sides to be inserted into the positioning steel plate, completing the fixed installation of the positioning steel plate and the injection mold body. The assembly and disassembly steps are convenient. Attached Figure Description

A universal shaft 8 is rotatably connected to the top of the second universal joint 9. A first universal joint 7 is rotatably connected to the top of the universal shaft 8. A support plate 3 is fixedly connected to the top of the first universal joint 7. A first outer shell 4, a second outer shell 6, and a third outer shell 10 are circumferentially connected above the base 5. Each of the first outer shell 4, the second outer shell 6, and the third outer shell 10 has an adjustment mechanism inside. The adjustment mechanism includes a servo motor 18. One end of the output shaft of the servo motor 18 is connected to a reciprocating lead screw 17. One end of the reciprocating lead screw 17 is rotatably connected to... A bearing housing 12 is connected to the outer side of the reciprocating screw 17, and a ball nut assembly 11 is connected to the outer side of the ball nut assembly 11.

The top of the second hinge seat 16 is fixedly connected to the support plate 3. When the servo motor 18 is turned on, the reciprocating screw 17 is driven to rotate, which drives the ball nut assembly 11 and the fixing sleeve 13 to move back and forth. Through the connection of the support frame 15, it is convenient to drive the support plate 3 at the top position of the support frame 15 to shift its angle.

[0027] like Figures 5-6 As shown, the injection mold body 1 and the bubble level 26 are connected to the upper part of the support plate 3. A pair of positioning steel plates 2 are connected to the bottom of the injection mold body 1. Both ends of the positioning steel plates 2 penetrate the interior of the support plate 3. A second through hole 23 is opened at both ends of the positioning steel plates 2. A positioning mechanism is set inside the second through hole 23. The positioning mechanism includes an insert plate 20. One end of the insert plate 20 penetrates the interior of the second through hole 23, and the top of the insert plate 20 is slidably connected to the support plate 3. By pressing the insert plate 20 on both sides, the return spring 21 is squeezed, which makes it easy to remove the insert plates 20 on both sides from the positioning steel plates 2, and thus makes it easy to remove the positioning steel plates 2 on both sides from the bottom of the injection mold body 1.
