Abstract
Description
Technical Field
[0001] The utility model relates to the field of molds, in particular to an injection mold structure with multi-directional slider movement. Background Art
[0002] In the process of injection mold design, due to the assembly and shape of the product itself, many holes and snap fits and other undercuts are designed. In mold design, these product features cannot be directly demolded. Generally, lifters or slider structures are designed for demolding. As shown in the attached Figure 4 product and the attached Figure 5 , Figure 6 product sectional view shown. When demolding such products, it is necessary to first demold through the slider structure shown in the attached Figure 6 (i.e., horizontal slider undercut demolding in the X direction), and then perform lifter demolding (i.e., undercut demolding along the Z direction). The above demolding method requires two sets of driving mechanisms to drive the slider structure demolding and lifter demolding respectively. As shown in the attached Figure 7 existing injection mold, its lifter demolding generally uses an oil cylinder system for driving. Such molds often have a too large volume due to the setting of the oil cylinder system, which in turn increases the thickness of the mold, and also results in a relatively high production cost of the whole mold and a long manufacturing cycle of the mold.
[0003] Facing the above problems, the optimization and innovation of the slider design for adjacent position snap fits is very important. Since the snap fit at the oil cylinder position of the product is a stud with a certain angle along the Z-axis direction (as shown in the attached Figure 5 , the stud of the snap fit at the oil cylinder position of the product forms a 20° angle with the Z direction), the slope of this stud is too large to use a lifter, so it can only be demolded by tunnel slider core pulling. Due to the structure, only slider core pulling can be selected. In order to simplify the mold structure, reduce the mold cost, and shorten the mold manufacturing cycle, it is necessary to study how to design two sliders with two different movement directions on the same driving mechanism. Summary of the Utility Model
[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an injection mold structure with multi-directional slider movement to solve the technical problems raised in the above background art.
[0005] The purpose of the utility model is achieved by the following technical solutions:
[0006] An injection mold structure with multi-directional slider movement includes a slider base. A slider B and a lifter are connected to the slider base. The lifter is arranged below the slider B, and both the slider B and the lifter are arranged along the X-axis direction. The slider B is fixedly installed on the mold, and a slider A is also connected to the mold. The slider A is arranged obliquely along the Z-axis and forms a certain inclination angle with the Z-axis. A slope is provided at the end of the lifter away from the slider base, and a cavity matching the slope is provided on the slider A. The lifter is sleeved on the slider A through the cavity.
[0007] In the above-mentioned utility model content, further, the inclination angle of the slope of the lifter is 15° - 25°.
[0008] In the above-mentioned utility model content, further, a slider pressure strip is provided on the side of the slider base.
[0009] In the above-mentioned utility model content, further, slider base limit blocks are provided in the walking direction of the slider base along the X-axis.
[0010] In the above-mentioned utility model content, further, slider wear-resistant blocks are provided on the slider base.
[0011] The beneficial effects of the present utility model are as follows: By providing a lifter on the slider structure, during the product demolding process, one slider base drives two adjacent sliders at different angles to complete the core-pulling movement simultaneously, simplifying the mold structure, overcoming the problem of the large thickness of the mold caused by the oil cylinder slider core-pulling mechanism, reducing the production cost of the mold and shortening the manufacturing cycle of the mold.

[0022] Embodiment:
[0023] An injection mold structure with multi-directional slide movement. Refer to the attached Figure 1 As shown in the figure, it includes a slide base 1, on which a slide B 2 and a lifter base 3 are connected. A slide wear-resistant block 10 is arranged on the slide base 1, and a slide strip 8 is arranged on the side of the slide base 1. The lifter base 3 is arranged below the slide B 2, and both the slide B 2 and the lifter base 3 are arranged along the X-axis direction; the slide B 2 is fixedly installed on the mold 4, and a slide A 5 is also connected to the mold 4. Refer to the attached Figure 2 and the attached Figure 3 As shown in the figure, the slide A 5 is arranged obliquely along the Z-axis and forms a certain inclination angle with the Z-axis. The inclination angle is the same as the angle of the inclined buckle head of the injection product. The attached Figure 3 As shown in the figure, the slide A 5 forms an angle of 20° with the Z-axis. This angle can be adjusted according to the angle of the inclined buckle head of the injection product, and the angle of this angle is not limited in this application. Continuing to refer to the attached Figure 1 and the attached Figure 3 As shown in the figure, an inclined surface 6 is arranged at the end of the lifter base 3 away from the slide base 1. The inclination angle of the inclined surface 6 of the lifter base 3 is preferably set to 15° - 25°. A cavity 7 that cooperates with the inclined surface 6 is arranged on the slide A 5, and the lifter base 3 is sleeved on the slide A 5 through the cavity 7.
[0024] In the specific use of the utility model, when the mold is opening, the slider seat 1 moves along the X-axis direction under the drive of the front mold inclined guide column, and the slider seat 1 is provided with a slider seat limit block 9 in the travel direction of the X-axis to limit the maximum travel of the slider seat 1. The slider B2 is fixedly arranged with the slider seat 1, so when the slider seat 1 moves in the X-axis direction, it drives the slider B2 to move horizontally in the X-axis direction, and completes the buckle demoulding of the mold in the horizontal X-axis direction. At the same time, the slider seat 1 gives driving force to the shovel base 3, and drives the shovel base 3 to move in the X-axis direction. The inclined surface of the shovel base 3 moves outward along the cavity 7 of the slider A5, and guides the slider A5 during the movement, so that the slider A5 moves along the demoulding direction of the inclined column head of the product. Then the inclined top demoulding (inverted buckle demoulding along the Z direction) is completed.
[0025] In the present invention, a shovel base is arranged on the slide structure, and the shovel base replaces the complicated oil cylinder mechanism. A slide seat 1 drives two slides in different directions to perform core pulling and demolding movements, thereby simplifying the mold structure, overcoming the problem of large mold thickness caused by the oil cylinder slide core pulling mechanism, and generating significant economic benefits.
[0026] Verification example:
[0027] As attached Figure 5 and attached Figure 6 As shown, the maximum stroke of the product in the oblique direction is 15.5mm, and the maximum demoulding stroke of the product along the X-axis direction is 6.89mm. In order to ensure safe and complete demoulding, the demoulding in the oblique direction needs to be greater than 15.5mm. In this verification example, the maximum stroke of the product in the oblique direction is S=20mm, the inclination angle of the inclined surface 6 of the shovel base 3 is set to 25°, and the movement stroke of the sliding seat 1 is L.
[0028] During the movement of the slide 1, the trigonometric function shows that the motion vector H of the slide B2 along the Z axis can be expressed as H = cos20°*S or H = tan25°*L according to the trigonometric function relationship; the two equations can be combined to obtain L = (cos20°*S) / tan25°; and then S = 20 is substituted into the above formula, that is, L = cos20°*20mm / tan25° = 50.38mm. This value is much larger than the maximum demoulding stroke of the product along the X axis, which is 6.89mm. That is, when the slide A5 completes the demoulding, the slide B2 can also complete the demoulding.
[0029] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
