Description
Technical Field
The utility model relates to a piston processing equipment field, concretely relates to piston top mould locking frock.
Background
The piston industry currently uses single, double and four die casting machines. The single-mold casting machine and the double-mold casting machine are generally applied in the industry, while the four-mold casting machine can produce four pistons at one time, so that the production efficiency is higher, but the four-mold casting machine is not common. Because the mould needs two pairs of double moulds at one time, once one pair of moulds breaks down, the casting of the other pair is also influenced, and the production is stopped. The main reason is that the top die needs to be removed for spraying treatment every shift, so that the number of connecting screws is large during installation and disassembly, the screws need to be screwed out one by one each time, and the time is very troublesome and delayed. Therefore, the time is wasted, the consumption is higher for workers, and the production efficiency is greatly influenced.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the to-be-solved technical problem of the utility model is to provide a piston top mould locking frock can enough be fixed with top mould locking, and loading and unloading are convenient simultaneously, improve machining efficiency.
In order to achieve the above purpose, the present invention is realized by the following technical solution: a piston top die locking tool comprises a top die, a locking piece and a top die connecting disc, wherein the top die comprises a top die oil cylinder connecting rod, a locking piece and the top die connecting disc;
the top die connecting disc is provided with a protrusion, the top die oil cylinder connecting rod is provided with a groove, the protrusion can be inserted into the groove, and the locking piece is arranged at the connecting part of the top die oil cylinder connecting piece and the top die connecting disc.
Insert the recess of a mould hydro-cylinder connecting rod to the arch of a mould connection pad, rethread retaining member is fixed, can accomplish the installation, only needs to take off the retaining member when lifting off, can accomplish the dismantlement.
The beneficial effect of above-mentioned piston top mould locking frock is: compared with a screw connection mode in the prior art, the sliding insertion loading and unloading mode is more convenient, the connection is stable, the time is saved, and the processing efficiency is improved.
Further, the protrusion is T-shaped, the groove is a T-shaped groove, and the protrusion is connected with the groove in a sliding mode.
The T-shaped bulges and the T-shaped grooves can only slide along one direction, can avoid relative rotation and are more stable in connection.
Furthermore, a plurality of threaded through holes are formed in the top die connecting disc in the circumferential direction, and the top die connecting disc is connected with a top die through screws.
Because of the top mould connection pad does not need often to dismantle with the top mould, consequently adopt a plurality of screws to fix, make to connect more firm, promote the machining precision.
Further, the locking piece is a locking sleeve, and the locking sleeve is sleeved on the top die oil cylinder connecting rod.
When in use, the locking sleeve is only required to be sleeved on the connecting rod of the top die oil cylinder, and automatically slides to the joint of the bulge and the groove under the action of gravity to lock the bulge and the groove, so that the use is convenient, and the connection is stable.
Further, the locking piece is a clamp.
The tightness degree can be adjusted to the clamp, promotes the dynamics of locking.

Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby. In the description of the present application, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the referenced components or structures must have a particular orientation, be constructed and operated in a particular orientation, and therefore, are not to be considered as limiting the present invention.
Referring to fig. 1, the utility model provides a piston top mould locking frock, including top mould 1, top mould connection pad 100, top mould hydro-cylinder connecting rod 200 and retaining member, top mould connection pad 100 sets up on top mould 1, and top mould hydro-cylinder connecting rod 200 sets up on top mould connection pad 100 to it is fixed through the retaining member.
Specifically, the top die connecting plate 100 has a protrusion 110 thereon, the lower end of the top die cylinder connecting rod 200 has a groove 210, and the protrusion 110 can be inserted into the groove 210. After the top die oil cylinder connecting rod 200 is inserted into the top die connecting plate 100, the top die oil cylinder connecting rod can start to work by being locked by the locking piece.
In order to fix the top die cylinder connecting rod 200 stably and prevent the protrusion 110 and the groove 210 from rotating relatively, in the present embodiment, the protrusion 110 and the groove 210 are both T-shaped, so that the top die cylinder connecting rod 200 can move only in one direction after being inserted into the top die connecting plate 100.
Specifically, in the present embodiment, the locking member used is the locking sleeve 300, and the locking sleeve 300 is slidably connected to the top mold cylinder connecting rod 200. After the top die oil cylinder connecting rod 200 is inserted into the top die connecting plate 100, the locking sleeve 300 is sleeved on the top die oil cylinder connecting rod 200, and under the action of gravity, the locking sleeve 300 automatically slides to the joint of the protrusion 110 and the groove 210, is locked and cannot move.
In other embodiments, a locking member such as a clamp can be used, and the clamp can adjust the tightness to ensure that the fastening is firmer.
Specifically, the top die connecting plate 100 is provided with a plurality of threaded through holes along the circumferential direction, and the threaded through holes are provided with screws 120. The top die connecting plate 100 is screwed with the top die 1 by screws 120. The top die 1 and the top die connecting disc 100 are not required to be frequently disassembled, so that the top die is more stable and not troublesome in a threaded connection mode.
The working principle of the piston top die locking tool is as follows: during installation, the T-shaped groove 210 at the lower end of the top die oil cylinder connecting rod 200 is aligned with and inserted into the T-shaped protrusion 110 of the top die connecting disc 100, the locking sleeve 300 is sleeved on the top die oil cylinder connecting rod 200 after insertion, and under the action of gravity or external force, the locking sleeve 300 slides to the joint of the groove 210 and the protrusion 110, so that the top die oil cylinder connecting rod 200 and the top die connecting disc 100 are fixed and cannot move. When the locking sleeve 300 is detached, the locking sleeve can be detached conveniently only by pulling out the locking sleeve.
Use above-mentioned piston top mould locking frock, can be in the installation with dismantle when the top mould, all very convenient, only need with the lock sleeve sheathe in or extract can, compare in traditional screw mode of twisting screw in turn, efficiency is higher, and saved workman's labour, improved production efficiency.
