[0017] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
[0018] The following describes a mold structure of an automobile oil pipe provided by some embodiments of the utility model in conjunction with the accompanying drawings.
[0019] Example:
[0020] Combination Figure 1-3 As shown, the utility model provides a mold structure of an automobile oil pipe, comprising a front mold core 1, a rear mold core 4 buckled with the front mold core 1, a water transport hole 10 is opened on the front mold core 1 and the rear mold core 4, and the water transport holes 10 on the front mold core 1 and the rear mold core 4 are connected through, a dome needle 7 is inserted at the bottom of the rear mold core 4, a slider three 2 is installed in the middle of the rear mold core 4, and a slider one 5 is inserted on one side of the rear mold core 4, and a slider four 8 is inserted on the other side of the rear mold core 4, and the slider Slider 1 5 and slider 4 8 are relatively arranged on both sides of the rear mold core 4, slider 2 3 is inserted at the front end of the rear mold core 4, slider 3 2 and slider 2 3 are arranged on the same side of the rear mold core 4, and the directions of slider 3 2 and slider 2 3 are staggered with each other, a glue inlet channel 9 is installed at the glue inlet position of the front mold core 1, and shrinkage bevel needles 6 are installed at the staggered positions of the geotechnical dome needles 7 at the bottom of the rear mold core 4. The number of shrinkage bevel needles 6 is four, and the shrinkage bevel needles 6 are all clamped at the bottom of the rear mold core 4.
[0021] Specifically, by setting four sliders, namely slider three 2, slider two 3, slider one 5 and slider four 8, during demolding, the product can be quickly taken out of the die cavity by removing slider four 8, slider two 3, slider one 5 and slider three 2 in sequence, thereby achieving rapid demolding, greatly improving the demolding efficiency of the mold, and also ensuring the quality of demolding, without damaging the product, thereby greatly improving the yield rate.
