Detailed Description

The following are specific embodiments of the present invention and are further described with reference to the accompanying drawings, but the present invention is not limited to these embodiments.

As shown in fig. 1 to 5, the top punching structure with the anti-sticking function includes: a base 1; the sliding body 2 is arranged on the base 1 in a sliding mode, and the elastic piece 3 is arranged on the sliding body 2; a support plate 4 movably arranged on the sliding body 2 and connected with the elastic part 3; the top plate 5 is detachably connected with the abutting plate 4, the top plate 5 is movably abutted against the base 1, and a plurality of ejector pins 6 are arranged on the top plate 5; and the movable die holder 7 is fixedly arranged on the sliding body 2 and movably abutted against the movable die holder 7, and the thimble 6 movably penetrates through the movable die holder 7.

The movable die holder 7 and the thimble 6 are both attached to a product 17, the sliding body 2 is connected with an external oil cylinder, when the die is opened, the external oil rod pulls the sliding body 2 which is arranged on the base 1 in a sliding way to move backwards, the movable die base 7 jointed with the product 17 begins to be separated from the product 17, in the process that the movable die base 7 moves backwards along with the sliding body 2 and the product 17 is separated, the thimble 6 is always pressed against the product 17 by the elastic force of the elastic part 3 on the pressing plate 4, and gives a certain downward pressure to the product 17, so as to ensure that the product 17 does not deform along with the movement of the movable die holder 7, when the movable die base 7 is completely separated from the product 17, the tail part of the movable die base 7 is movably abutted against the front end surface of the top plate 5, then the top plate 5 moves backwards under the pressure of the mold base 7 and enables the base 1 to be separated from abutting, and in the process that the top plate 5 moves backwards, the ejector pin 6 on the top plate 5 is also separated from contact with the product 17, namely, quick demolding is realized; when the die is closed, the external oil cylinder pushes the sliding body 2 arranged on the base 1 in a sliding mode to move forwards, the movable die holder 7 also moves forwards along with the sliding body 2 until the top plate 5 abuts against the base 1, and then the tail portion of the movable die holder 7 is separated from the front end face of the top plate 5 to be in contact with the front end face of the top plate, namely, the movable die holder is reset to the initial state.

The sliding body 2 is provided with a first limiting groove 8 and a second limiting groove 9, the elastic piece 3 is arranged on the first limiting groove 8 and connected with the abutting plate 4, and the movable die holder 7 is fixedly arranged on the second limiting groove 9.

The second limiting groove 9 is located outside the first limiting groove 8, when the sliding body 2 moves backwards, the top plate 5 can be separated from the base 1 and abutted against the movable die holder 7, the ejector pin 6 ejects the movable die holder 7, when the sliding body 2 moves forwards, the top plate 5 can be separated from the movable die holder 7 and abutted against the base 1, and the ejector pin 6 resets and returns to the movable die holder 7.

Guide grooves 10 are formed in two side walls of the base 1, guide portions 11 are arranged at two ends of the top plate 5, and the guide portions 11 are arranged on the guide grooves 10 in a sliding mode.

As shown in fig. 2, the guide grooves 10 on the two side walls of the base 1 are located at the first limiting groove 8, so as to ensure that a certain gap is formed between the movable mold base 7 and the top plate 5 in the initial state, and through the gap, the ejector pin 6 can press the product 17 when the movable mold base 7 moves backwards, so as to ensure that the movable mold base 7 and the product 17 are smoothly separated from each other and attached.

The guide groove 10 has a first limiting surface 12, the guide portion 11 has a second limiting surface 13, and the second limiting surface 13 is movably abutted against the first limiting surface 12.

The second limiting surface 13 is abutted against the first limiting surface 12, so that a certain gap is formed between the movable die holder 7 and the top plate 5.

The movable die holder 7 is provided with a top hole 14, and the thimble 6 movably penetrates through the top hole 14.

The ejector pin 6 passes through the top hole 14 to complete the abutment with the product 17.

The two sides of the lower end of the sliding body 2 are provided with sliding blocks 15, the two sides of the base 1 are provided with sliding grooves 16, and the sliding blocks 15 are connected with the sliding grooves 16 in a sliding mode.

The slide block 15 and the slide groove 16 are arranged to facilitate the slide body 2 to move forwards and backwards.
