Abstract
The invention discloses a hydraulic ejection structure of a plastic mold, which comprises: the oil hydraulic cylinder is arranged on the die leg of the plastic die; the oil way is arranged in the die leg and is communicated with the oil hydraulic cylinder; and one end of the connecting rod is fixed with the telescopic end of the oil hydraulic cylinder, and the other end of the connecting rod is fixed with the ejection plate of the plastic mold. Compared with the prior art, the hydraulic ejection structure of the plastic mold has the advantages that the oil way is arranged in the mold foot of the plastic mold, so that the oil pipe is prevented from being crushed in the processes of mold assembling, mold disassembling and transportation; the oil pipe is arranged in the die foot, so that the space is reduced, and the oil pipe cannot interfere with other structures outside the die; the service life is longer than that of an oil pipe; after the oil hydraulic cylinder is assembled, the subsequent maintenance and die removal do not need to be carried out on the oil hydraulic cylinder, and the oil leakage problem does not exist.
Description
[ technical field ] A method for producing a semiconductor device
The invention relates to a hydraulic ejection structure, in particular to a hydraulic ejection structure of a plastic mold.
[ background of the invention ]
The reverse pouring of the male mold is a common mold structure in plastic mold design, and the mold for the reverse pouring of the male mold is basically ejected by a hydraulic (oil pressure cylinder).
Referring to fig. 1, fig. 1 is a first perspective cross-sectional view of a hydraulic ejection structure of a plastic mold according to the prior art, and fig. 2 is a second perspective cross-sectional view of the hydraulic ejection structure of the plastic mold according to the prior art.
As shown in the figure, the hydraulic ejection structure comprises an oil hydraulic cylinder 101, an oil collection block 102, an oil pipe joint 103 and an oil pipe 104. With this structure, the following disadvantages are present: 1. because the oil pipe 104 is arranged on the outer side of the plastic mold, the oil pipe is easily crushed in the processes of mold filling, mold removing and transportation; 2. the oil pipe 104 easily interferes with other structures outside the mold; 3. the oil pipe 104 is easy to age and has short service life; 4. after the oil pipe 104 is repaired and removed, the mold has a large amount of oil leakage to the site, which affects the environmental sanitation.
In view of the above, there is a need to develop a hydraulic ejection structure for a plastic mold to solve the above problems.
[ summary of the invention ]
Therefore, the invention aims to provide a hydraulic ejection structure of a plastic mold, which solves the problems that the existing hydraulic ejection structure is short in service life, easy to crush and interfered with other structures of the plastic mold.
In order to achieve the above object, the present invention provides a hydraulic ejection structure for a plastic mold, including:
the oil hydraulic cylinder is arranged on the die leg of the plastic die;
the oil way is arranged in the die leg and is communicated with the oil hydraulic cylinder;
and one end of the connecting rod is fixed with the telescopic end of the oil hydraulic cylinder, and the other end of the connecting rod is fixed with the ejection plate of the plastic mold.
Optionally, the oil path is drilled in the die leg.
Optionally, the connecting rods have mutually perpendicular connecting portions.
Compared with the prior art, the hydraulic ejection structure of the plastic mold has the advantages that the oil way is arranged in the mold foot of the plastic mold, so that the oil pipe is prevented from being crushed in the processes of mold assembling, mold disassembling and transportation; the oil pipe is arranged in the die foot, so that the space is reduced, and the oil pipe cannot interfere with other structures outside the die; the service life is longer than that of an oil pipe; after the oil hydraulic cylinder is assembled, the subsequent maintenance and die removal do not need to be carried out on the oil hydraulic cylinder, and the oil leakage problem does not exist.

[ detailed description ] embodiments
Referring to fig. 3 and 4, fig. 3 is a first perspective sectional view of a hydraulic ejection structure of a plastic mold according to the present invention, and fig. 4 is a second perspective sectional view of the hydraulic ejection structure of the plastic mold according to the present invention.
In order to achieve the above object, the present invention provides a hydraulic ejection structure for a plastic mold, including:
the oil hydraulic cylinder 201 is arranged on a mold leg 202 of the plastic mold;
the oil path 203 is arranged in the die leg 202 and is communicated with the oil hydraulic cylinder 201;
and a connecting rod 204, one end of which is fixed with the telescopic end of the hydraulic cylinder 201, and the other end of which is fixed with an ejection plate 205 of the plastic mold.
Wherein, the oil path 203 is drilled in the die pin 202.
The connecting rod 204 has mutually perpendicular connecting portions, and is fixed to the hydraulic cylinder 201 and the ejector plate 205, respectively.
Compared with the prior art, the hydraulic ejection structure of the plastic mold has the advantages that the oil way 203 is arranged in the mold foot 202 of the plastic mold, so that the oil pipe is prevented from being crushed in the processes of mold filling, mold removing and transportation; the oil pipe is arranged in the die foot 202, so that the space is reduced, and the oil pipe cannot interfere with other structures outside the die; the service life is longer than that of an oil pipe; after the oil pressure cylinder 201 is assembled, the subsequent maintenance and die removal do not need to remove the oil pressure cylinder 201, and the oil leakage problem does not exist.
It should be noted that the present invention is not limited to the above embodiments, and any simple modification, equivalent change and modification made to the above embodiments by those skilled in the art based on the technical solution of the present invention fall within the protection scope of the present invention.
