[0002] An injection mold is various molds and tools for obtaining required products by injection molding, blow molding, and extrusion methods. As an essential production equipment for large-scale industrial products, its reliability and automation level directly affect the production quality and efficiency of injection products. Among them, in-mold cutting means cutting the injection mold inside the injection mold when the injection product is still in the lower mold and has not been demolded. However, the existing technology has the following deficiencies in use:

[0003] After the injection mold is cut, it needs to be taken out of the mold cavity. Manual material taking is time-consuming and laborious, affecting production efficiency. At the same time, it will also increase the work intensity of the staff, and the practicability is relatively low.

[0004] Therefore, there is an urgent need for a product in-mold cutting mechanism to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to address the problem that after the injection mold is cut, it needs to be taken out of the mold cavity. Manual material taking is time-consuming and laborious, affecting production efficiency. At the same time, it will also increase the work intensity of the staff, and the practicability is relatively low.

[0006] To achieve the above-mentioned invention purpose, the utility model provides the following technical solutions:

[0007] A product in-mold cutting mechanism to improve the above problems.

[0008] Specifically, this application is as follows:

[0009] A product in-mold cutting mechanism includes a lower mold. A mold cavity and a connection groove are formed at the top of the lower mold. A first electric push rod is installed in the connection groove. The push rod end of the first electric push rod is fixedly connected with a mounting seat. A cutting knife is installed on the mounting seat. A knife groove is formed at the top of the lower mold. A connection seat is installed at the bottom of the lower mold. A second electric push rod is installed on the connection seat. The push rod end of the second electric push rod is fixedly connected with a trapezoidal block. An inclined groove is formed at the top of the trapezoidal block. A first slider is slidably connected in the inclined groove. The top of the first slider is fixedly connected with a connecting plate. Symmetrically distributed T-shaped grooves are formed on the lower mold. Symmetrically distributed T-shaped top plates are fixedly connected to the top of the connecting plate.

[0010] As a preferred technical solution of this application, a fixing plate is fixedly connected to the connection seat. A sliding groove is formed at the top of the fixing plate. A second slider is slidably connected in the sliding groove. The trapezoidal block is fixedly connected to the second slider.

[0032] Embodiment:

[0033] As Figures 1-7As shown in the figure, a product in-mold cutting mechanism proposed in this embodiment includes a lower mold 1. A mold cavity 2 and a connection groove 3 are formed at the top of the lower mold 1. A first electric push rod 4 is installed in the connection groove 3. After the injection mold is cooled and formed in the mold cavity 2, the first electric push rod 4 is started. The push rod end of the first electric push rod 4 is fixedly connected with a mounting seat 5. A cutting knife 6 is installed on the mounting seat 5. A knife groove 7 is formed at the top of the lower mold 1. The first electric push rod 4 drives the cutting knife 6 to move through the mounting seat 5 to cut off the injection mold in the mold cavity 2. A connection seat 8 is installed at the bottom of the lower mold 1. A second electric push rod 9 is installed on the connection seat 8. The push rod end of the second electric push rod 9 is fixedly connected with a trapezoidal block 10. The second electric push rod 9 is started to drive the trapezoidal block 10 to move outward through the second electric push rod 9. An inclined groove 11 is formed at the top of the trapezoidal block 10. A first slider 12 is slidably connected in the inclined groove 11. The top of the first slider 12 is fixedly connected with a connecting plate 13. Since the inner bottom wall of the inclined groove 11 is an inclined surface, when the trapezoidal block 10 moves, the first slider 12 and the connecting plate 13 move upward. Symmetrically distributed T-shaped grooves 14 are formed on the lower mold 1. Symmetrically distributed T-shaped top plates 15 are fixedly connected to the top of the connecting plate 13. The connecting plate 13 drives the two T-shaped top plates 15 to move upward in the two T-shaped grooves 14, and the injection mold in the mold cavity 2 is ejected through the two T-shaped top plates 15.

[0034] As Figure 1 , Figure 4 and Figure 7 shown, a fixing plate 16 is fixedly connected to the connection seat 8. A sliding groove 17 is formed at the top of the fixing plate 16. A second slider 18 is slidably connected in the sliding groove 17. The trapezoidal block 10 is fixedly connected to the second slider 18. When the trapezoidal block 10 moves, the second slider 18 slides in the sliding groove 17, which can ensure the stability of the trapezoidal block 10 when it moves.

[0035] As Figure 1 and Figure 6 shown, the T-shaped top plate 15 slides in the T-shaped groove 14, and the injection mold in the mold cavity 2 is ejected through the two T-shaped top plates 15.

[0036] As Figure 6 shown, the T-shaped groove 14 is communicated with the mold cavity 2, which is convenient for subsequently ejecting the injection mold in the mold cavity 2 through the T-shaped top plate 15.

[0037] As Figure 1 shown, the connection seat 8 is fixedly connected to the lower mold 1.

[0038] As Figure 3 and Figure 6 shown, the cutting knife 6 is located in the knife groove 7, and the injection mold in the mold cavity 2 is cut off by the cutting knife 6.

[0039] Specifically, when the in-mold cutting mechanism of this product is in use: electrically connect the first electric push rod 4 and the second electric push rod 9 to an external control power supply. After the injection mold is cooled and formed in the mold cavity 2, start the first electric push rod 4. The first electric push rod 4 drives the cutting knife 6 to move through the mounting seat 5 to cut off the injection mold in the mold cavity 2. Then start the second electric push rod 9, and drive the trapezoidal block 10 to move outward through the second electric push rod 9. The second slider 18 slides in the chute 17. Since the inner bottom wall of the inclined chute 11 is an inclined surface, when the trapezoidal block 10 moves, the first slider 12 and the connecting plate 13 move upward. The connecting plate 13 drives the two T-shaped top plates 15 to move upward in the two T-shaped grooves 14, and the injection mold in the mold cavity 2 is ejected by the two T-shaped top plates 15, reducing the labor intensity of the staff, saving time and effort while improving work efficiency, with higher practicability and a wider scope of application.
