Description

TECHNICAL FIELD

[0001] The utility model relates to the field of plastic circuit breaker, concretely relates to a plastic circuit breaker mould with anti-locking function. BACKGROUND

[0002] The plastic circuit breaker, more accurately, is a plastic housing type circuit breaker, which is a protective electrical appliance widely used in low-voltage distribution systems. The plastic circuit breaker mould is a key tool for manufacturing the plastic housing type circuit breaker. The plastic circuit breaker mould is usually composed of two parts, i.e. the movable mould and the fixed mould, which contain various structure components such as the cavity, the core, the slider, and the insert required for forming the plastic parts. These components work together to ensure that the plastic can be uniformly and quickly filled into the cavity during the injection molding process, thereby obtaining the plastic circuit breaker housing that meets the requirements.

[0003] The existing plastic circuit breaker mould has the problem of locking during use due to the operation and internal extrusion during the mould closing process. If the plastic circuit breaker mould lacks the anti-locking function, it will cause production interruption, increase downtime and production cost. Moreover, forcibly opening and closing the mould after long-term use will cause damage or deformation of the mould.

[0004] Therefore, it is necessary to invent a plastic circuit breaker mould with anti-locking function to solve the above problems. SUMMARY

[0005] The utility model aims to provide a plastic circuit breaker mould with anti-locking function. Through the outer guide sleeve, the outer guide column, the positioning hole, the upper inner mould, the positioning column, the mould opening block, the telescopic pneumatic cylinder, and the mould opening column, the plastic circuit breaker mould has the anti-locking function. Through accurate mould positioning, the possibility of mould locking due to misalignment is reduced. Not only is the production interruption avoided, but also the risk of mould damage is reduced, and the service life of the mould is prolonged. Moreover, the telescopic pneumatic cylinder makes the mould opening process smoother and more efficient, which reduces the need for manual intervention to forcibly open the mould, improves the production efficiency, and reduces the probability of mould locking due to material deformation, wear, or residue after long-term use.

Specific implementation

[0026] In order to make those skilled in the art better understand the technical scheme of the utility model, the utility model will be further introduced in detail below with the drawings.

[0027] The utility model provides a kind of plastic circuit breaker mould with anti-locking as shown in Figures 1-5 It comprises lower die seat 1, and the main body for bearing plastic circuit breaker mould;

[0028] Positioning bolt 2 is passed through the upper portion of lower die seat 1, for assisting mold installation, and the upper portion of lower die seat 1 is fixedly installed with circuit breaker lower mold 3, the outside of lower die seat 1 is fixedly installed with lower stiffening platform 4, the upper portion of lower stiffening platform 4 is fixedly installed with outer guide sleeve 5, and outer guide sleeve 5 is inlaid with outer guide column 6 in the inside, and the top of outer guide column 6 is fixedly installed with upper stiffening platform 7, and the outside of upper stiffening platform 7 is fixedly installed with upper die seat 8;

[0029] Liquid injection port 9 is arranged at the upper portion of upper die seat 8, for injection liquid to enter, and the inside of circuit breaker lower mold 3 is provided with positioning slot 10, positioning slot 10 is inlaid with positioning block 11 in the inside, and positioning block 11 is fixedly installed with lower inner mold 12 outside, and the upper portion of lower inner mold 12 is provided with positioning hole 15, and the lower portion of upper die seat 8 is fixedly installed with circuit breaker upper mold 16, and circuit breaker upper mold 16 is provided with upper inner mold 17 in the inside, and the bottom of upper inner mold 17 is fixedly installed with positioning column 18;

[0030] The opening module 22 is fixedly arranged on the outside of the circuit breaker upper mold 16 on both sides to assist in opening the mold, and the outside of the lower mold base 1 is fixedly installed with a telescopic cylinder 23, and the top of the telescopic cylinder 23 is fixedly installed with an opening column 24. In use, the circuit breaker upper mold 16 needs to align the outer guide sleeve 5 of the circuit breaker lower mold 3, and then the positioning column 18 of the upper inner mold 17 is inserted into the positioning hole 15 of the lower inner mold 12. The double positioning of the inner and outer molds can not only avoid the misalignment of the mold, but also reduce the probability of the mold being locked due to misalignment when the molds are closed in sequence. Then, when the mold is opened, the telescopic cylinder 23 drives the opening column 24 to abut against the opening module 22 of the circuit breaker upper mold 16, giving the circuit breaker upper mold 16 an upward force, thereby assisting in opening the mold.

[0031] As shown in Figure 1 , Figure 2 and Figure 3 , the number of outer guide sleeves 5 is four, and the four outer guide sleeves 5 are distributed at equal intervals on the lower mold base 1. The positioning of the outer guide sleeves 5 can not only avoid misalignment of the mold, but also reduce the probability of the mold being locked due to misalignment when the molds are closed in sequence. The positioning clamping block 11 fixedly installed at the bottom of the lower inner mold 12 is clamped and connected with the positioning clamping groove 10 opened in the inside of the circuit breaker lower mold 3. The positioning clamping block 11 and the positioning clamping groove 10 are used in cooperation, so that the appropriate lower inner mold 12 can be selected according to the current production needs of the plastic circuit breaker, and installed in the circuit breaker lower mold 3 through the positioning clamping groove 10 and the positioning clamping block 11. The circuit breaker lower mold 3 penetrates the side reinforcing pin 13 on the outside, and the lower inner mold 12 has the side reinforcing groove 14 opened on the outside. The side reinforcing pin 13 is inserted into the side reinforcing groove 14 to reinforce the stability of the lower inner mold 12 in the circuit breaker lower mold 3.

[0032] As shown in Figure 1 , Figure 4 and Figure 5 , the circuit breaker upper mold 16 is fixedly installed with an upper clamping block 19 on the outside, and the circuit breaker lower mold 3 is fixedly installed with a lower clamping block 20 on the outside. The outside of the upper clamping block 19 and the lower clamping block 20 is sleeved with an outer clamping sleeve 21. After the mold is closed, the outer clamping sleeve 21 can be sleeved on the upper clamping block 19 and the lower clamping block 20 on the outside of the circuit breaker upper mold 16 and the circuit breaker lower mold 3, thereby enhancing the stability after the mold is closed. The opening column 24 is movably connected with the opening module 22, and the telescopic cylinder 23 is symmetrically arranged with the central axis of the lower mold base 1. When the mold is opened, the telescopic cylinder 23 drives the opening column 24 to abut against the opening module 22 of the circuit breaker upper mold 16, giving the circuit breaker upper mold 16 an upward force, thereby assisting in opening the mold.

[0033] The working principle of this practical application is as follows: First, take out the plastic circuit breaker mold and install it on the injection molding equipment using the positioning bolts 2 of the lower mold base 1. Then, connect the external power supply. Select a suitable lower inner mold 12 according to the production requirements of the plastic circuit breaker. Install it in the lower mold 3 of the circuit breaker using the positioning slots 10 and positioning blocks 11. Next, reinforce the stability of the lower inner mold 12 in the lower mold 3 by inserting the side reinforcing pins 13 into the side reinforcing grooves 14. At this point, the mold can be closed, and the circuit breaker will be installed. Mold 16 needs to align the outer guide post 6 with the outer guide sleeve 5 of the lower mold 3 of the circuit breaker. Then, the positioning post 18 of the upper inner mold 17 is inserted into the positioning hole 15 of the lower inner mold 12. This double positioning not only avoids misalignment during mold closing but also reduces the probability of the plastic circuit breaker mold locking due to misalignment during sequential mold closing. Then, during mold opening, the telescopic cylinder 23 can drive the mold opening post 24 to abut against the opening module 22 of the upper mold 16 of the circuit breaker, giving the upper mold 16 an upward force, thereby assisting... The design of the mold-opening aid enables the plastic circuit breaker mold to prevent locking. Through precise mold-closing positioning, the possibility of mold locking due to misalignment is reduced, which not only avoids production interruption but also reduces the risk of mold damage and extends the service life of the mold. Moreover, the telescopic cylinder 23 makes the mold-opening process smoother and more efficient, which reduces the need for manual intervention to force the mold to open, and improves production efficiency. After the mold is closed, an outer clamping sleeve 21 can be fitted onto the upper clamping block 19 and lower clamping block 20 on the outside of the upper mold 16 and the lower mold 3 of the circuit breaker, thereby enhancing the stability after mold closure. After the plastic circuit breaker mold is closed, the external injection molding equipment can inject the injection liquid through the injection port 9 of the upper mold base 8 to complete the production. After the product is formed, the mold can be opened normally. Finally, after completing all the installation and use of the plastic circuit breaker mold according to the above operations, the mold should be maintained and cleaned regularly. If it is not used for a long time, the external power supply should be disconnected. In this way, the use of the plastic circuit breaker mold with anti-locking is completed.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
