In order to achieve the above purpose, the utility model adopts the following technical scheme:

a piston mold structure comprises two groups of mold assemblies which are symmetrically arranged, wherein each mold assembly comprises a sliding block, a movable rod and a pin, the top of each sliding block is provided with a protruding part, each protruding part is used for being matched with a concave part on the outer side of a piston, the upper part of each sliding block is provided with a yielding hole for the pin to pass through, and the lower part of each sliding block is fixedly provided with a pin shaft;

the pin is fixed at the top of movable rod along the horizontal direction, and the front end of movable rod is equipped with a spout, and the spout includes slope section and the horizontal segment that sets up in the slant by preceding to back according to the preface, round pin axle sliding connection in the spout of slider lower part, the connection of movable rod is in an actuating mechanism, and this actuating mechanism drive movable rod moves along the horizontal direction.

Further, the driving mechanism is an oil cylinder.

Furthermore, the pin is locked and fixed on the movable rod through a screw.

By adopting the technical scheme, in the demoulding process, the movable rod moves backwards to drive the pin to move backwards synchronously, so that the pin is separated from the piston, when the movable rod continues to slide backwards, the pin shaft on the slide block moves downwards in the sliding process of the inclined section, so that the protruding part on the slide block is separated from the concave part on the piston, and the sequential demoulding in two directions is realized; the utility model discloses simple structure, convenient operation.

Drawings

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments;

FIG. 1 is a cross-sectional view of a piston;

fig. 2 is a front view of the present invention;

fig. 3 is a perspective view of the mold assembly after disassembly.

Detailed Description

As shown in fig. 2-3, the present invention relates to a piston mold structure, which includes two sets of mold assemblies 1 symmetrically disposed, each of the two mold assemblies 1 includes a sliding block 11, a movable rod 12 and a pin 13, the top of the sliding block 11 has a protruding portion 111, the protruding portion 111 is used for cooperating with a concave portion outside the piston, the upper portion of the sliding block 11 has a yielding hole 112 for the pin 13 to pass through, and the lower portion of the sliding block 11 is fixed with a pin 14;

the pin 13 is fixed on the top of the movable rod 12 along the horizontal direction, a sliding groove 121 is arranged at the front end of the movable rod 12, the sliding groove 121 sequentially comprises an inclined section and a horizontal section which are arranged obliquely upwards from front to back, wherein the included angle between the inclined section and the horizontal plane is 20-25 degrees, and the larger the angle is, the smaller the sliding resistance of the sliding block 11 is.

The pin 14 at the lower part of the sliding block 11 is slidably connected in the sliding groove 121, and the movable rod is connected to a driving mechanism which drives the movable rod 12 to move along the horizontal direction.

Preferably, the driving mechanism is an oil cylinder.

Further, the pin 13 is fixed to the movable rod 12 by a screw lock. The rear end of pin 13 has the connector, and the up end of connector is the plane, and the top of connector and movable rod 12 is equipped with the screw hole respectively, and when the connector cup jointed at the top of movable rod 12, the screw hole of the two was coaxial, then locked into two screw holes and screwed in proper order through the screw to fix pin 13 on movable rod 12.

The utility model discloses a theory of operation: the movable rod 12 of the slide block 11 drives the slide block 11 to move along the track of the slide slot 121, so that the slide block 11 moves up and down.

In the process of die assembly, the movable rod 12 moves forwards, the slide block 11 moves upwards along the inclined section, the convex part 111 at the top of the slide block 11 is inserted into the corresponding concave part at the outer side of the piston, the movement continues to move forwards, and the pin 13 is inserted into the abdicating hole 112 on the slide block 11 and penetrates into the pin hole of the piston to form the die assembly action.

In the demolding process, the movable rod 12 moves backwards to drive the pin 13 to synchronously move backwards, so that the pin 13 is separated from the piston, when the movable rod 12 continuously slides backwards, the slide block 11 moves downwards in the sliding process of the pin shaft 14 on the slide block 11 at the inclined section, so that the protruding part 111 on the slide block 11 is separated from the concave part on the piston, and the sequential demolding in two directions is realized; the utility model discloses simple structure, convenient operation.

The practice of the present invention has been described with reference to the accompanying drawings, but the invention is not limited to the embodiments described above, which are illustrative rather than limiting, and it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
