Description

Technical Field

[0001] The utility model relates to the technical field of fully automated processing molds supporting multi-directional core pulling, and more specifically, to a fully automated processing mold supporting multi-directional core pulling. Background Art

[0002] like Figure 1 The cross-sectional view of the plastic part shown in FIG. 1 is a cross-sectional view of a plastic part. The plastic part requires a mold to be designed for automated production. The difficulty lies in completing the undercut core pulling in two directions. In the prior art, there are two solutions:

[0003] The first solution is to design a slanted top structure within the slider, with the core-pulling mechanism in direction 1 designed as a slider and the core-pulling mechanism in direction 2 as a slanted top structure. During mold opening, the core-pulling mechanism in direction 1 is simultaneously driven by the slanted top structure in direction 2. However, this structure is limited by the size of the plastic product and cannot be used to design parts with this structure (the resulting part would be very thin and not durable).

[0004] The second solution is to design the slider core for direction 2 as a front-mold inclined slider, and for direction 1 as a slider structure. When opening the mold, the inclined slider core for direction 2 is pulled first, followed by the slider core for direction 1. When closing the mold, the slider for direction 1 must be reset before the inclined slider for direction 2. This structure requires careful control of the mold opening sequence, resulting in a high risk of part collision during production. Furthermore, due to the structural size limitations of the plastic part, it is difficult to achieve high part strength. Utility Model Content

[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The fully automated processing mold supporting multi-directional core pulling in the preferred embodiment of the present invention is as follows Figure 1 See also Figures 2 to 6 ; It includes a transverse core pulling mechanism 100 and an oblique core pulling mechanism 200; wherein the oblique core pulling mechanism 200 is provided on the transverse core pulling mechanism 100 and slides on the transverse core pulling mechanism 100, the transverse core pulling mechanism 100 is fixedly connected to the first core pulling member 300, and the oblique core pulling mechanism 200 is fixedly connected to the second core pulling member 400;

[0037] The oblique core pulling mechanism 200 is driven by the first driving mechanism (not shown) to obliquely insert or withdraw the second core pulling member 400 into or out of the workpiece 500 to be processed, and the transverse core pulling mechanism 100 is driven by the second driving mechanism 600 to transversely insert or withdraw the first core pulling member 300 into or out of the workpiece 500 to be processed;

[0038] During core pulling, the oblique core pulling mechanism 200 is driven by the first driving mechanism to pull the second core pulling member 400 obliquely out of the workpiece 500, and then the transverse core pulling mechanism 100 is driven by the second driving mechanism 600 to pull the first core pulling member 300 transversely out of the workpiece 500; wherein the first driving mechanism is a machine tool, and the second driving mechanism 600 is an oil cylinder or a pneumatic cylinder, etc.

[0039] The oblique core pulling mechanism 200 is driven by the first driving mechanism to obliquely insert or pull out the second core pulling member 400 into or out of the body to be processed 500, and the transverse core pulling mechanism 100 is driven by the second driving mechanism 600 to transversely insert or pull out the first core pulling member 300 into or out of the body to be processed 500; wherein, during core pulling, the oblique core pulling mechanism 200 is driven by the first driving mechanism to obliquely pull out the second core pulling member 400 into the body to be processed 500, and then the transverse core pulling mechanism 100 is driven by the second driving mechanism 600 to transversely pull out the first core pulling member 300 into the body to be processed 500, and vice versa; thereby, oblique and transverse core pulling processing of the body to be processed 500 is realized, and the structure is simple, the cost is low, the size is small, and it is easy to use, and it is widely applicable to the multi-directional core pulling processing of small parts.

[0040] like Figures 2 to 6 As shown, the second core-pulling component 400 passes through the first core-pulling component 300 to meet different usage requirements.

[0041] like Figures 2 to 6 As shown, the transverse core pulling mechanism 100 includes a middle slider 110;

[0042] The middle slider 110 is provided with an inclined surface protrusion 111 and an inclined core pulling mechanism 200 , which includes an inclined slider 210 , a fork puller 220 and a bent pin 230 ;

[0043] The fork puller 220 is provided with two symmetrical first oblique notches 221 , and the inclined slider 210 is provided with two first oblique protrusions 211 that match the two first oblique notches 221 one by one. The first oblique protrusions 211 move back and forth in the first oblique notches 221 . The inclined slider 210 and the fork puller 220 are fitted together on the inclined protrusions 111 .

[0044] The fork puller 220 is provided with a second oblique notch 222, and the bent pin 230 is provided with a second oblique protrusion 231 that matches the second oblique notch 222. The second oblique protrusion 231 moves back and forth in the second oblique notch 222.

[0045] The second core-pulling member 400 is fixedly connected to the end of the inclined slider 210 away from the fork-pulling member 220 , thereby achieving a simple structure, a small volume, and a low cost.

[0046] like Figures 2 to 6As shown, the first driving mechanism drives the bent pin 230 to move up and down. When the bent pin 230 moves up and down, it guides the fork member 220 to move back and forth laterally through the second oblique notch 222.

[0047] When the fork puller 220 moves back and forth laterally, it guides the inclined slider 210 on the inclined surface of the inclined surface protrusion 111 through the first inclined notch 221 to move back and forth obliquely. When the inclined slider 210 moves back and forth obliquely, the second core-pulling member 400 is obliquely inserted into or pulled out of the workpiece 500.

[0048] The fork puller 220 moves back and forth laterally on the middle slider 110 , thereby achieving a simple structure, small size and low cost.

[0049] like Figures 2 to 6 As shown, the inclined surface of the inclined surface projection 111 forms an acute angle with the bottom surface of the middle slider 110 ; the angle is set according to the required inclination angle of the second core-pulling component 400 .

[0050] like Figure 2 and Figure 3 as well as Figure 5 and Figure 6 As shown, two symmetrical fork member pressing blocks 223 are fixedly connected to the middle slider 110, and the fork member pressing blocks 223 limit the up and down movement of the fork member 220, so as to facilitate installation.

[0051] like Figure 2 and Figure 3 as well as Figure 5 and Figure 6 As shown, the transverse core pulling mechanism 100 further includes a slider seat 120, and the second driving mechanism 600 drives the middle slider 110 to move back and forth on the slider seat 120; the structure is simple;

[0052] Two symmetrical intermediate slider blocks 112 are fixedly connected to the slider seat 120. The intermediate slider blocks 112 restrict the upward and downward movement of the intermediate slider 110, making installation easier.

[0053] The first core-pulling member 300 is fixedly connected to an end of the middle slider 110 away from the second driving mechanism 600 .

[0054] like Figure 2 and Figure 3 as well as Figure 5 and Figure 6 As shown, the first driving mechanism also drives the middle slider locking block 700 to move up and down. When the middle slider locking block 700 moves up and down, it presses against the middle slider 110 or moves away from the middle slider 110.

[0055] When the middle slider locking block 700 presses against the middle slider 110 , it cooperates with the slider seat 120 to limit the middle slider 110 from moving back and forth on the slider seat 120 , thereby preventing the first core pulling member 300 from being driven to move when the second core pulling member 400 is pulled out first, thereby improving stability.

[0056] like Figures 2 to 6 As shown, the second core-pulling component 400 is provided with a hemispherical protrusion 410 to meet different usage requirements.

[0057] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims appended to this utility model.
