It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0023] Embodiment 1

[0024] In order to solve the technical problems in the background technology, a locking mechanism 2 of a novel electric mold frame 1 is provided as follows:

[0025] Combination Figure 1 , Figure 2 ,and Figure 3 As shown,

[0026] A novel locking mechanism 2 of an electric mold frame 1, the locking mechanism 2 is used to position and lock the upper mold frame 3 and the column 4 of the electric mold frame 1, and the locking mechanism 2 includes:

[0027] A locking tooth plate 211, which is longitudinally fixedly disposed on the side of the column 4 corresponding to the electric mold frame 1;

[0028] A fixing block 212, which is vertically fixed to the end surface of the upper mold frame 3 of the electric mold frame 1, and a through hole is formed in the fixing block 212, and the through hole is arranged opposite to the locking tooth plate 211;

[0029] A latch pin 213 is axially slidably inserted into the through hole of the fixing block 212, and the end surface of the latch pin 213 facing the locking tooth plate 211 is provided with tooth patterns for staggered engagement with the locking tooth plate 211;

[0030] A cylinder 214, which is disposed on the outer side of the fixing block 212, and the end of the piston rod of the cylinder 214 is axially fixedly connected to the other end face of the latch 213;

[0031] The latch 213 includes a first working state and a second working state. When in the first working state, the cylinder 214 drives the latch 213 to retract into the through hole of the fixing block 212, and the latch 213 is separated from the locking tooth plate 211; when in the second working state, the cylinder 214 pushes the latch 213 to engage and lock with the locking tooth plate 211.

[0032] By adopting the above technical solution, the locking mechanism 2 is divided into two parts, one part is that a locking tooth plate 211 is fixedly arranged on the side of the column 4 of the electric mold frame 1, and the other part is that the cylinder 214 and the latch 213 are correspondingly arranged on the end face of the upper mold frame 3 of the electric mold frame 1 through the fixing block 212, and the end face of the latch 213 facing the locking tooth plate 211 is provided with a tooth pattern that is staggered and engaged with the locking tooth plate 211, so that the cylinder 214 pushes the latch 213 to insert into the locking tooth plate 211, which can increase the contact area in the locked state, and the locking range is lengthened, thereby making the locking more secure and eliminating the existing safety hazards.

[0033] Embodiment 2

[0034] Combination Figure 1 , Figure 3 and Figure 4 As shown, based on the above embodiment, this embodiment further provides the following content: a slide plate 216 is attached to the end face of the upper mold frame 3 of the electric mold frame 1, and the slide plate 216 is slidably attached to the inner side surface of the corresponding column 4, and the fixed block 212 is fixed on the outer surface of the slide plate 216.

[0035] By adopting the above technical solution, the slide plate 216 is arranged on the end face of the upper mold frame 3, and the outer facade thereof is provided with a fixing block 212 of the locking mechanism 2. As the upper mold frame 3 rises when opening the mold and descends when closing the mold, the fixing block 212 is guaranteed to slide stably, which not only increases the sliding stability of the upper mold frame 3 and the locking structure, reduces the jitter during the operation of the locking mechanism 2, but also improves the locking accuracy, extends the service life, and reduces the use and maintenance costs.

[0036] Embodiment 3

[0037] Combination Figure 2 , Figure 3 As shown, the through hole is a square structure, and copper plates 215 are symmetrically attached to the inner top and bottom surfaces thereof, and the two copper plates 215 are slidably attached to the top and bottom surfaces of the latch 213, respectively.

[0038] By adopting the above technical solution, the copper plate 215 is placed between the pin 213 and the fixed block 212, which can not only increase the structural support stability, facilitate the movement of the pin 213 back and forth, and reduce friction, but also can be disassembled and assembled during actual use, saving space during the transportation of the locking mechanism 2. When it wears out and fails, it can be replaced separately, reducing maintenance costs, extending service life, and improving economic benefits.

[0039] Embodiment 4

[0040] Combination Figure 2 , Figure 3 , Figure 4As shown, based on the above embodiment, this embodiment further provides the following contents: a signal bracket 218 is provided on the outer side of the fixing block 212, a signal screw 217 is provided on the side of the latch 213 opposite to the signal bracket 218, and the signal bracket 218 is provided with a proximity switch for detecting whether the latch 213 is locked in place.

[0041] By adopting the above technical solution, the proximity switch on the signal bracket 218 can not only reduce the control difficulty and save costs, but also ensure that the locking mechanism 2 operates stably when the upper mold frame 3 is closed and raised, and is not easy to fall, thereby reducing accidental losses and improving the safety factor.

[0042] Embodiment 5

[0043] Combination Figure 2 , Figure 3 As shown, based on the above embodiment, this embodiment further provides the following content: the tooth pattern of the latch 213 is a rectangular slot structure.

[0044] By adopting the above technical solution, the rectangular slotted teeth of the latch 213 can not only improve the operational tolerance, eliminate safety hazards, and increase the stability of the locking engagement, but also the tooth pattern design is reasonable and simple, which is conducive to processing and reduces the initial processing cost and subsequent maintenance cost.

[0045] The working principle and use process of this utility model:

[0046] When the locking mechanism 2 of the utility model is implemented, when the upper mold frame 3 descends for mold closing, the cylinder 214 is started to drive the latch 213 to separate from the locking tooth plate 211, and after the proximity switch detects that the latch 213 and the locking tooth plate 211 are unlocked in place, the cylinder 214 stops working, and the upper mold frame 3 smoothly descends to complete the mold closing; when the upper mold frame 3 rises for mold opening, the cylinder 214 is started to push the latch 213 and the locking tooth plate 211 to engage and lock, and after the proximity switch detects that the latch 213 and the locking tooth plate 211 are engaged in place, the cylinder 214 stops working, and the upper mold frame 3 smoothly rises to complete the mold opening.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
