When the power source 26 of the slider structure 100 provides a driving force to move towards the workpiece 300, since a larger pressure is required to compress the damping member 71, the power source 26 firstly drives the slider seat 50 and the guide seat 10 to integrally move towards the workpiece 300, when the guide seat 10 moves to a position abutting against the workpiece 300 or a preset positioning position, the position of the slider seat 50 is fixed, at this time, the power source 26 continues to provide the driving force, and then the driving force compresses the damping member 71, so that the telescopic rod 262 pushes the fixing member 25 to move towards the direction of the guide seat 10, and thus the connecting rod assembly 20 and the rotating assembly 30 can be driven to move, so that the functional assembly 40 compresses or inserts into the workpiece 300. After the workpiece 300 is machined, the power source 26 provides returning power, at this time, because the damping member 71 has a certain elastic damping, at this time, the damping member 71 is reset first, the telescopic rod 262 is retracted partially first, at this time, the fixing member 25 is retracted along with the telescopic rod 262, the fixing member 25 is retracted while driving the connecting rod assembly 20 and the rotating assembly 30 to move, finally, the functional assembly 40 is separated from the workpiece 300, and after the damping member 71 is reset, the power source 26 drives the slider seat 50 and the guide seat 10 to return to the initial positions through the telescopic rod 262.

Referring to fig. 10, in another embodiment, an injection mold 200 for forming a porous workpiece 300 is provided. The injection mold 200 includes a male mold 1 and a female mold 2 that mates with the male mold 1 to collectively form a work piece 300.

The workpiece 300 is set at a substantially central position of the male die 1. The male mold 1 is provided with a second accommodating cavity 80, and the slider structure 100 is arranged in the second accommodating cavity 80. The slider structure 100 corresponds to a cavity (not shown) in the male mold 1 for forming the workpiece 300, and the slider structure 100 is movable relative to the male mold 1. In a specific embodiment, three slider structures 100 are disposed in the injection mold 200, and the three slider structures 100 are disposed along the circumference of the workpiece 300 to simultaneously machine the workpiece 300. Since the slider structure 100 is applied to the injection mold 200, the connecting member 41 of the functional component 40 is a core back insert seat, and the functional component 42 is a core back insert.

Referring to fig. 10, the male mold 1 further includes a housing 81 and a stopper 82, and the housing 81 and the stopper 82 are also disposed in the second receiving cavity 80. The housing 81 is disposed on the surface of the slider seat 50 for protecting the slider seat 50. The stopper 82 is located on the side wall of the second accommodating cavity 80 to limit the stroke of the slider seat 50, so as to prevent the slider seat 50 from being damaged when the slider structure 100 moves, due to the impact of the slider seat 50 on the side wall of the male die 1.

Referring to fig. 10, preferably, the male mold 1 further includes an ejection mechanism 90, and the ejection mechanism 90 is disposed at a substantially central position of the male mold 1 and located at a lower end of the slider seat 50. The ejection mechanism 90 corresponds to the workpiece 300, so that after the workpiece 300 is machined and the slider seat 50 is retracted, the workpiece 300 is ejected from the male die 1, and the workpiece 300 is taken out conveniently. It is understood that the ejection mechanism 90 may be composed of an oil hydraulic cylinder and an ejector rod, or an oil hydraulic cylinder and an ejector block. In an injection mold, the ejection mechanism is common, and further description is omitted here.

Referring to fig. 10, the female mold 2 is used to cooperate with the male mold 1 to accommodate the slider structure 100 together for processing a workpiece 300.

It can be understood that the connection or guidance between the male mold 1 and the female mold 2 through the structure of guide pillar, guide sleeve, etc. is also a common technique in mold design. Therefore, the structures will not be described in detail.

Referring to fig. 1, fig. 2 and fig. 10, the injection mold 200 forms the porous workpiece 300 according to the following principle:

after the male mold 1 and the female mold 2 are closed, the power source 26 drives the connecting rod assembly 20 to move towards the direction close to the guide seat 10, the damping part 71 is compressed, the angle between the connecting rod 21 and the swing rod 22 arranged on the same mounting part 24 is increased, the connecting plate 31 rotates, the shifting column 323 moves in the inclined groove 411, so that the driving function part 42 protrudes into a cavity forming the workpiece 300, and after injection molding is completed, a porous workpiece 300 is formed.

When the workpiece 300 is to be cored, the power source 26 drives the connecting rod assembly 20 to move away from the workpiece 300. The link 21 and the swing link 22 provided on the same mounting member 24 are moved in the second sliding groove 241 from the original end to the opposite end thereof, and the angle therebetween is gradually decreased until it is decreased to the original predetermined angle. The connecting rod 21 rotates the connecting plate 31, and the shifting column 323 moves from the end far from the workpiece 300 to the end close to the workpiece 300 in the inclined groove 411, so that the functional component 40 moves in the avoiding opening 12 in the direction away from the workpiece 300, and finally the functional component 42 moves to the edge position of the workpiece 300. At this time, the damper 71 is reset. The female die 2 and the male die 1 are separated, and the female die 2 leaves the male die 1 from a parting surface position. The power source 26 further drives the slider holder 50 to move to the initial position in a direction away from the workpiece 300. The ejection mechanism 90 ejects the workpiece 300 from the male mold 1 so that the workpiece 300 can be taken away, and finally, the workpiece 300 with multiple layers of round holes which are staggered and closely arranged is formed by injection molding.

In other embodiments, the functional component 40 may be replaced by a clamping block for fixing the workpiece 300, and the clamping block may be designed according to the shape of the workpiece 300, so that the whole structure of the male die 1 can also be used as a clamping fixture. The functional assembly 40 may be replaced with a cutting assembly or the like for machining the workpiece 300.

In summary, the injection mold 200 provided above does not need to increase the length of the core back insert in order to provide a plurality of slider seats, and only by providing the connecting plate 31 connected to the connecting rod assembly 20 on the guide seat 10, further providing the functional component 40 connected to the connecting plate 31, and providing the functional component 40 on the guide seat 10, the functional component 40 can move in the guide seat 10 and can protrude into the cavity forming the workpiece 300, so as to form the hole in the workpiece 300 at the same time as forming the workpiece 300. The functional elements 42 in the functional assembly 40 need not be intentionally lengthened to form multiple layers of staggered and closely spaced circular holes in the workpiece 300. The thrust required by the power source 26 is greatly reduced through the connecting rod 21 and the swing rod 22, and meanwhile, the connecting plate 31 can be effectively prevented from loosening. In other embodiments, the functional element 40 is replaced by a clamping block, so that the male mold 1 can be used as a clamp, such as a clamp for a round bar type workpiece. Thereby expanding the application range of the injection mold 200.

In addition, those skilled in the art should recognize that the above-described embodiments are illustrative only, and should not be taken as limiting the invention, and that changes and modifications can be made without departing from the spirit and scope of the invention.
