Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
Example 1
A core pulling mechanism on a plastic product mold sliding block comprises a sliding block seat 4 and a sliding block head 11 which are connected, wherein a pressure plate installation groove 4.1 is formed in one side of the sliding block seat 4, a pressure plate 8 is fixedly installed in the pressure plate installation groove 4.1 through a plurality of fastening screws 3, and a plurality of sliding block insert pieces 7 are connected to the bottom surface of the pressure plate installation groove 4.1; one end of the slide block insert 7 is provided with a resin pouring groove 7.1, and the slide block insert passes through an insert jack 8.1 arranged on the pressing plate 8 and is telescopically connected with a core-pulling hole 12 arranged on the slide block head 11; big distance screw jacks 13 corresponding to a plurality of positions are respectively formed in the slider seat 4 and the pressing plate 8, big distance screws 2 are movably connected in the big distance screw jacks 13 corresponding to every two positions, a big spring 10 is arranged between the bottom surface of the pressing plate mounting groove 4.1 and the slider head 11, the big spring 10 is positioned in the big distance screw jacks 13, and one end of the big distance screw 2 penetrates through the big spring 10 and is fixedly connected with the slider head 11.
A plurality of small distance screw insertion holes 14 are symmetrically formed in two sides of the sliding block seat 4, small distance screws 1 are movably connected in the small distance screw insertion holes 14, small springs 5 are arranged between the peripheries of the small distance screw insertion holes 14 and the sliding block heads 11, and one ends of the small distance screws 1 penetrate through the small springs 5 to be fixedly connected with the sliding block heads 11.
The core-pulling principle of the mechanism is as follows: because the product to be demoulded has a plurality of inclined surfaces and is tightly wrapped with the sliding block, if the product is demoulded directly, the product is easy to deform, therefore, the utility model decomposes the demoulding resistance, as shown in figure 2, when the mould is opened, the power mechanism of the mould provides power, the sliding block seat 4 moves horizontally leftwards, the sliding block insert 7 fastened on the sliding block seat 4 is driven by the sliding block seat 4, horizontally moving leftwards relative to the slider head 11 in the core-pulling hole 12 to finish the first-step resistance decomposition, so that a molded product in the resin pouring groove 7.1 is separated from loosening, and after the slider seat 4 moves leftwards for a core-pulling distance, the large distance screw 2 and the small distance screw 1 are pulled, the large distance screw 2 and the small distance screw 1 drive the slider head 11 to horizontally move leftwards, the demoulding resistance decomposition of the part outside the slider head 11 is completed, and the side product is separated from a certain distance in the process, so that the core-pulling purpose is achieved. As shown in fig. 3, when the mold is closed, the mold power mechanism provides power, the slider seat 4 moves horizontally to the right, and the large spring 10 and the small spring 5 push the slider head 11 to move rightwards after receiving the acting force of the slider seat 4 until the slider head 11 resets, and at this time, the slider seat 4 continues to move horizontally to the right to push the slider insert 7 to complete the resetting.
