Description

Technical Field

[0001] The utility model relates to the field of mold sliders, and particularly relates to a mold slider delay structure. Background Technique

[0002] When designing a mold, due to undercuts, an auxiliary slider needs to be added inside the main slider so that the product can be demolded. Since it is inside the main slider, the auxiliary slider can only be driven by a spring. Due to the structural reasons of the product in this solution, when demolding, the sliding directions of the main slider and the auxiliary slider are different and need to have a sequence, so the previous diagonal pressure structure cannot achieve automation.

[0003] The existing solution is to drive the auxiliary slider with a diagonal pressure structure. When demolding, the auxiliary slider is driven by a spring, while the main slider is manually operated. That is to say, the driving structures of the two sliders are not synchronized, which affects the production efficiency.

[0004] In view of the above problems, the utility model designs and manufactures a mold slider delay structure to overcome the above defects. Content of the Utility Model

[0005] For the problems existing in the prior art, a mold slider delay structure provided by the utility model can use the same diagonal pressure structure to simultaneously press down the main slider and the auxiliary slider, and can ensure that when opening the mold, the auxiliary slider moves first. After the movement of the auxiliary slider ends, the main slider moves and drives the auxiliary slider to continue moving until the product can be demolded.

[0006] To achieve the above object, the technical solution adopted by the utility model is as follows: A mold slider delay structure includes a first slider, and a first pressing block is fitted on one side of the first slider. Pressing down the first pressing block can drive the first slider to move in a first direction;

[0007] A groove is provided on the upper surface of the front side of the first slider, a channel is provided at the rear side of the groove, a second slider is provided in the groove and the channel, a second pressing block is fitted on the side of the second slider away from the channel, the first pressing block and the second pressing block are connected to the same downward pressing template. Pressing down the second pressing block can drive the second slider to move in a second direction, and the first direction and the second direction are perpendicular to each other on a horizontal plane;

[0008] The surface of the first slider that cooperates with the first pressing block is defined as the first mating surface, and the first mating surface includes a first inclined surface and a first vertical surface connected to the lower part of the first inclined surface; the surface of the first pressing block that cooperates with the first slider is defined as the second mating surface, and the second mating surface includes a second inclined surface, the inclination angle of the second inclined surface is the same as that of the first inclined surface, a second vertical surface is connected to the lower part of the second inclined surface, and a third inclined surface is connected to the lower end of the second vertical surface, the inclination angle of the third inclined surface is the same as that of the second inclined surface. When the second vertical surface of the first pressing block cooperates with the first vertical surface of the first slider, the second pressing block presses down the second slider.

[0009] Preferably, the width of the groove is greater than the width of the second pressing block.

[0010] Preferably, the distance between the second pressing block and the second vertical surface on the first pressing block is slightly greater than the distance between the groove and the first vertical surface.

[0011] Preferably, the first slider is connected with a first spring. When the lower pressing template rises, the first spring will drive the first slider to move towards the first pressing block.

[0012] Preferably, a first groove is provided at a position on the bottom of the first slider away from the first pressing block, a first spring positioning hole is provided on the side wall of the first groove, and the first spring is installed in the first spring positioning hole.

[0013] Preferably, the second slider includes a second mating part and a second insertion part, the second insertion part is arranged on one side of the second mating part, and the second insertion part can extend into the channel;

[0014] A fourth inclined surface is provided on the second mating part to cooperate with the second pressing block.

[0015] Preferably, a second spring is provided between the second mating part and the rear side of the groove.

[0016] Preferably, a second spring positioning hole is provided at the rear side of the second mating part, and the second spring is installed in the second spring positioning hole.

[0017] Preferably, a positioning hole is provided at the front side of the groove, a positioning pin is provided in the positioning hole, and the positioning pin can limit the position of the second slider after demolding under the action of the second spring.

[0018] The beneficial effects of this utility model are as follows:

[0019] When the mold of the present utility model is opened, since the second vertical surface of the first pressing block still remains in contact with the first vertical surface of the first sliding block, the position of the first sliding block remains unchanged. However, the rising of the second pressing block will cause the second sliding block to retreat first. As the lower pressing template continues to rise, the second pressing block disengages from the groove until the third inclined surface cooperates with the first inclined surface. At this time, the rising of the first pressing block will drive the first sliding block to move. Since the second pressing block has disengaged from the groove, it will not interfere with the groove. At the same time, the first sliding block also disengages from the product. Finally, the lower pressing template drives the demolding of the first sliding block and the second sliding blocks in different directions on the first sliding block simultaneously.

Detailed Embodiment

[0028] For the convenience of those skilled in the art to understand, the present utility model will be further described below with reference to the accompanying drawings.

[0029] As Figures 1 to 7 shown, a mold slider delay structure includes a first sliding block 1. A first pressing block 2 is cooperated on one side of the first sliding block 1. The downward pressing of the first pressing block 2 can drive the first sliding block 1 to move in the first direction.

[0030] A groove 4 is provided on the upper surface of the front side of the first slider 1. A channel 13 is provided at the rear side of the groove 4. A second slider 5 is arranged in the groove 4 and the channel 13. A second pressing block 3 is fitted on the side of the second slider 5 away from the channel 13. The first pressing block 2 and the second pressing block 3 are connected to the same downward pressing template. When the second pressing block 3 presses down, it can drive the second slider 5 to move in the second direction, and the first direction and the second direction are perpendicular to each other on the horizontal plane.

[0031] In the present utility model, the surface of the first slider 1 that cooperates with the first pressing block 2 is set as the first cooperation surface, and the first cooperation surface includes a first inclined surface 11 and a first vertical surface 12 connected to the lower part of the first inclined surface 11; the surface of the first pressing block 2 that cooperates with the first slider 1 is set as the second cooperation surface, and the second cooperation surface includes a second inclined surface 21. The inclination angle of the second inclined surface 21 is the same as that of the first inclined surface 11. A second vertical surface 22 is connected to the lower part of the second inclined surface 21. A third inclined surface 23 is connected to the lower end of the second vertical surface 22, and the inclination angle of the third inclined surface 23 is the same as that of the second inclined surface 21. When the second vertical surface 22 of the first pressing block 2 cooperates with the first vertical surface 12 of the first slider 1, the second pressing block 3 presses down the second slider 5.

[0032] When the mold is opened, since the second vertical surface 22 of the first pressing block 2 still remains in contact with the first vertical surface 12 of the first slider 1, the position of the first slider 1 remains unchanged. However, when the second pressing block 3 rises, the second slider 5 will retreat first. As the downward pressing template continues to rise, the second pressing block 3 disengages from the groove 4 until the third inclined surface 23 cooperates with the first inclined surface 11. At this time, when the first pressing block 2 rises, it will drive the first slider 1 to move. Since the second pressing block 3 has disengaged from the groove 4, it will not interfere with the groove 4. At the same time, the first slider 1 also disengages from the product. Finally, a downward pressing template drives the demolding of the first slider 1 and the second slider 5 in different directions on the first slider 1 at the same time.

[0033] Specifically, the width of the groove 4 is greater than the width of the second pressing block 3 to avoid interference between the second pressing block 3 and the groove 4. The distance between the second pressing block 3 and the second vertical surface 22 on the first pressing block 2 is slightly greater than the distance between the groove 4 and the first vertical surface 12, ensuring that when the second vertical surface 22 cooperates with the first vertical surface 12, the second pressing block 3 enters the groove 4 to cooperate with the second slider 5 in the groove 4.

[0034] The first slider 1 of the present utility model is connected with a first spring. When the downward pressing template rises, the first spring will drive the first slider 1 to move towards the first pressing block 2. Preferably, a first groove 4 is provided at the position of the bottom of the first slider 1 away from the first pressing block 2, and a first spring positioning hole 14 is provided on the side wall of the first groove 4. The first spring is installed in the first spring positioning hole 14.

[0035] The second slider 5 of the present utility model includes a second mating portion 51 and a second insertion portion 52. The second insertion portion 52 is provided on one side of the second mating portion 51. The second insertion portion 52 can extend into the channel 13. A fourth inclined surface is provided on the second mating portion 51 to cooperate with the second pressing block 3. A second spring is provided between the second mating portion 51 and the rear side of the groove 4 to ensure that the second slider 5 can be demolded when the second pressing block 3 rises. Preferably, a second spring positioning hole 14 is provided at the rear side of the second mating portion 51, and the second spring is installed in the second spring positioning hole 14.

[0036] A positioning hole 14 is provided at the front side of the groove 4, and a positioning pin is provided in the positioning hole 14. The positioning pin can limit the position of the second slider 5 under the action of the second spring after demolding.

[0037] When the present utility model is closed, pressing down the template drives the first pressing block 2 and the second pressing block 3 to press down simultaneously. The third inclined surface 23 of the first pressing block 2 first cooperates with the first inclined surface 11 of the first slider 1 and drives the first slider 1 to move away from the first pressing block 2. At this time, the second pressing block 3 is still located above the first slider 1 until the second vertical surface 22 of the first pressing block 2 starts to cooperate with the first vertical surface 12 of the first slider 1. At this position, the moving position of the first slider 1 is in place. At this time, the second pressing block 3 is exactly located above the groove 4. As the pressing template continues to press down, since the first slider 1 and the first pressing block 2 are in cooperation with two vertical surfaces, the position of the first slider 1 does not move. The second pressing block 3 drives the second slider 5 to move through cooperation with the second slider 5 until the second inclined surface 21 of the first pressing block 2 cooperates with the first inclined surface 11 of the first slider 1. At this position, the moving position of the second slider 5 is exactly in place, and at this time, the wax injection molding product can be formed.

[0038] When opening the mold, since the second vertical surface 22 of the first pressing block 2 still remains in contact with the first vertical surface 12 of the first slider 1, the position of the first slider 1 does not move. However, the rising of the second pressing block 3 will cause the second slider 5 to retreat first. As the pressing template continues to rise, the second pressing block 3 disengages from the groove 4 until the third inclined surface 23 of the first pressing block 2 cooperates with the first inclined surface 11 of the first slider 1. At this time, the rising of the first pressing block 2 will drive the first slider 1 to move. Since the second pressing block 3 has disengaged from the groove 4, it will not interfere with the groove 4. At the same time, the first slider 1 also disengages from the product. Finally, a pressing template drives the demolding of the first slider 1 and the second slider 5 in different directions on the first slider 1 simultaneously.
