[0031] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.
[0032] like Figures 1 to 12 As shown, a special mold slider limiting structure includes a base 11, a mold core 1 is installed above the base 11, a product body 2 is installed above the mold core 1, slider inserts 6 are arranged on both sides of the mold core 1, and the slider seat 3 is connected to the slider insert 6, and the slider seat 3 can move. A circular inclined slot 4 is arranged in each slider seat 3, and an inclined guide column 5 is arranged on each slider seat 3. The inclined guide column 5 can be inserted through or pulled out of the circular inclined slot 4 of the slider seat 3. Two sets of limiting positions 12 are arranged at the bottom of the slider seat 3, see Figure 8 A pressure block 8 is provided under each slider seat 3, and the pressure block 8 is fixed to the base 11 by screws 7. An opening 13 is provided on the pressure block 8, and a floating pin 9 is provided under the opening 13. A spring 10 is provided at the bottom of each floating pin 9; the bottom of the spring 10 contacts the base 11, so that the floating pin 9 is pressed between the pressure block 8 and the base 11 by the spring 10, and the top of the floating pin 9 can be pushed out from the opening 13 of the pressure block 8 and enter the limit position 12, see Figures 10 to 12 .
[0033] like Figure 3 As shown, a plurality of grooves 14 are provided above the base 11 , and a group of pressing blocks 8 , screws 7 , floating pins 9 and springs 10 are installed in each groove 14 .
[0034] Figure 1 and Figure 2 There are two sets of mold cores and products. Take one set as an example to explain its structure. And for easy observation, remove the base.
[0035] like Figure 4 and Figure 5 As shown, when the mold is in the closed state, since the mold core 1 is in the middle and the product body 2 is placed above the mold core 1, components such as the slider seat 3 are respectively provided on the left and right sides of the mold core 1, and the slider seat 3 is located near the middle, that is, close to the mold core 1, and the inclined guide column 5 is inserted through the circular inclined groove 4 opened on the slider seat 3, so that the inclined guide column 5 is located on the slider seat 3 at this time, and the floating pin 9 is against a group of limit positions 12 set on the outside of the bottom of the slider seat 3.
[0036] like Figure 6 and Figure 7 As shown, when the mold is opened, the inclined guide column 5 is pulled out from the side, and the slider seat 3 can move on both sides due to the lateral force brought by the side pulling of the inclined guide column 5, until the core pulling distance of the inclined guide column 5 reaches the required position during the withdrawal of the inclined guide column 5. At this time, the slider seat 3 moves to the extreme positions on both sides, and the limit position 12 set on the slider seat 3 will be located directly above the floating pin 9. At this time, the floating pin 9 will be able to move freely up and down under the action of the spring, and then enter a group of limit positions 12 on the inner side of the bottom of the slider seat 3 for limiting.
[0037] like Figure 8 As shown, in a specific embodiment, each slider seat 3 is provided with a circular inclined slot 4, and each circular inclined slot 4 has an inclined guide column 5 movably penetrated therein, that is, the inclined guide column 5 can sometimes be inserted through the circular inclined slot 4 of the slider seat 3, and sometimes can be pulled out. Each slider seat 3 is in the shape of a front wheel. In this setting, the shape of the slider seat 3 is determined to make it more suitable for a special mold slider.
[0038] like Fig. 9 As shown, a pressure block 8 is arranged under each slider seat 3, and the pressure block 8 is fixed to the base 11 by screws 7. An opening 13 is opened on the pressure block 8, and a floating pin 9 is arranged under the opening 13. A spring 10 is arranged at the bottom of each floating pin 9.
[0039] See also Figures 8 to 12, a plurality of limit positions 12 are provided at the bottom of each slider seat 3, and the floating pin 9 is pressed against different limit positions 12 in the mold closing state and the mold opening state. In this setting, when in the initial mold closing state, the inclined guide column 5 is inserted through the slider seat 3, and the floating pin 9 is pressed against a group of limit positions 12 arranged on the outer side of the bottom of the slider seat 3; when the mold is opened, the inclined guide column 5 is pulled out sideways, and the slider arranged on the slider seat 3 can move on both sides due to the lateral force brought by the inclined guide column 5 being pulled out sideways, until the core pulling distance of the inclined guide column 5 reaches the required position during the process of pulling out the inclined guide column 5, at which time the floating pin 9 is pressed against a group of limit positions 12 arranged on the inner side of the bottom of the slider seat 3.
[0040] The limiting clamping position 12 opened at the bottom of each slider seat 3 is conical. In this setting, the shape of the limiting clamping position 12 opened at the bottom of the slider seat 3 is determined to make it more suitable for special mold sliders.
[0041] The top shape of each floating pin 9 matches the shape of the limit stop 12. In this configuration, the top shape of the floating pin 9 is determined to be more in line with the special mold slider.
[0042] The implementation principle of a special mold slider limiting structure of this embodiment is as follows:
[0043] See also Figures 1 to 12 First, the device is in a closed mold state at the beginning, with the mold core 1 in the middle, and the product body 2 placed above the mold core 1, and components such as the slider seat 3 are respectively provided on the left and right sides of the mold core 1, and the slider seat 3 is located near the middle. When the inclined guide column 5 is in a circular inclined slot 4 that passes through the slider seat 3, the inclined guide column 5 is located on the slider seat 3 at this time, and the floating pin 9 is pushed on the limit position 12 set on the outside of the bottom of the slider seat 3. When the mold is opened, the inclined guide column 5 is pulled out from the side, and the slider seat 3 can move on both sides due to the lateral force brought by the side pulling of the inclined guide column 5. At this time, the original set of limit positions 12 leave the top of the floating pin 9 until the core pulling distance of the inclined guide column 5 reaches the required position during the withdrawal of the inclined guide column 5. At this time, another set of limit positions 12 set on the slider seat 3 will be able to move to the position above the floating pin 9. At this time, the floating pin 9 will be able to move freely up and down under the action of the spring 10, and then enter the limit position 12 on the inner side of the bottom of the slider seat 3 for limiting.
