Description

Technical Field

[0001] This utility model relates to the field of injection molding technology, specifically to a mold structure and injection molding equipment with a slider-delayed core pulling mechanism. Background Technology

[0002] In existing injection mold structures, after injection molding and mold opening, the slider insert needs to be extracted from the mold structure. However, because the front and rear mold inserts clamp the slider insert, they must first retract to make room before the slider insert can be extracted. Extracting it before this retraction can damage the front and rear mold inserts. Currently, the common method to address this problem is hydraulic cylinder core pulling, where the cylinder pulls the core after the mold is fully opened. This method is cumbersome, results in a large mold layout, and is costly.

[0003] Patent document CN214082613U discloses a two-color injection molding slider shovel mold structure, including a front mold and a rear mold. The front mold includes a first molding cavity and a second molding cavity, and the rear mold has a sliding slider. The front mold has a first shovel and a second shovel, with a slanted baffle plate on the second shovel. The slider has a shifting groove, which contains a limiting block and a reset structure that can reset the limiting block. When the mold is closed, the slanted baffle plate can push open the limiting block and enter the shifting groove. When the mold is opened, the slanted baffle plate in the shifting groove can press the limiting block to retract the slider. However, this patent document still has the drawbacks of a cumbersome structure, large mold layout, and high cost. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a mold structure and injection mold equipment for a slider-delayed core pulling process.

[0005] According to the present invention, a mold structure for delayed core pulling of a slider includes: a shovel, a slider seat, a slider insert, a front mold insert, and a rear mold insert.

[0006] The front mold insert and the rear mold insert are used to connect one end of the slider insert, and the other end of the slider insert is disposed on the slider seat;

[0007] A first limiting abutment plane is provided on the side wall of the shovel that contacts the slider seat, and a second limiting abutment plane is provided on the side wall of the slider seat that contacts the shovel.

[0008] When the mold is closed, the first limiting abutment plane and the second limiting abutment plane come into contact and abut each other, forming a limiting structure that can limit the movement of the slider seat along the slider insert extraction direction;

[0009] When the mold is opened, after the shovel moves a preset distance along the mold opening direction, the first limiting abutment plane and the second limiting abutment plane are not in contact, and the slider seat can move along the extraction direction of the slider insert.

[0010] Preferably, the first limiting abutment plane and the second limiting abutment plane are two parallel vertical planes;

[0011] The mold opening direction of the mold structure is vertical, and the extraction direction of the slider insert is horizontal.

[0012] After the shovel moves a preset distance vertically, the first limiting abutment plane and the second limiting abutment plane are no longer in contact, and the slider seat can move horizontally in the extraction direction.

[0013] Preferably, a first inclined surface is provided on the side wall of the shovel that contacts the slider seat;

[0014] The first inclined surface is connected to the first limiting abutment plane and is located below the first limiting abutment plane;

[0015] A second inclined surface is provided on the side wall of the slider seat that contacts the shovel.

[0016] The second inclined surface is connected to the second limiting abutment plane and is located above the second limiting abutment plane;

[0017] The mold opening direction of the mold structure is vertically upward. When the first inclined surface moves to the position of the second inclined surface, the first limiting abutment plane and the second limiting abutment plane do not contact each other.

[0018] Preferably, the shovel is equipped with wear-resistant plates;

[0019] The wear-resistant plate is located between the slider seat and the shovel, and the wear-resistant plate is in contact with the slider seat.

[0020] This utility model also provides an injection mold equipment, including the above-mentioned slider delayed core pulling mold structure.

[0021] Preferably, the injection mold equipment also includes: a front mold core, a rear mold core, a front template, a rear template, and a rear mold support plate;

[0022] The front mold core and the shovel are mounted on the front template, and the rear mold core is mounted on the rear template; the rear template is mounted on the rear mold support plate, and the front template is mounted on the rear template;

[0023] The rear template and the rear mold support plate can move relative to each other to open and / or close the mold; the front template and the rear template can move relative to each other to open and / or close the mold.

[0024] The front mold insert is mounted on the front mold core; the rear mold insert is mounted on the rear mold support plate and passes through the rear mold core; the rear mold insert and the rear mold core are capable of relative movement.

[0025] Preferably, the injection molding equipment also includes: inclined guide pillars;

[0026] The inclined guide post is installed on the front template, and the slider seat is provided with an inclined guide hole. The inclined guide post passes through the inclined guide hole. There is a gap between the inclined guide post and one inclined inner wall of the inclined guide hole.

[0027] When the mold is closed, the inclined guide post does not contact the inclined inner sidewall;

[0028] During mold opening, the inclined guide post moves along the mold opening direction. When the first limiting abutment plane and the second limiting abutment plane are not in contact, the inclined guide post contacts the inclined inner sidewall and can drive the slider seat along the extraction direction of the slider insert.

[0029] Preferably, the injection molding equipment further includes: a mold opening mechanism assembly;

[0030] The mold opening mechanism assembly includes: a pull rod cylinder, a limit pin, and an outer sleeve;

[0031] The tie rod cylinder is installed on the front template, and the outer sleeve is installed on the rear template;

[0032] One end of the pull rod tube passes through the outer sleeve and forms a limiting end that abuts against the outer sleeve. The limiting end can be compressed into the outer sleeve and move within the outer sleeve.

[0033] The rear template is provided with the limiting pin, and the rear mold support plate is provided with a limiting member that can block the movement of the limiting pin.

[0034] Preferably, the rear mold support plate is provided with guide pillars;

[0035] The front template is provided with a front template guide sleeve, the guide post passes through the front template guide sleeve, and the front template guide sleeve can move on the guide post.

[0036] Preferably, a rear template guide sleeve is provided on the rear template;

[0038] Compared with the prior art, the present invention has the following beneficial effects:

[0039] 1. This utility model sets two limiting abutment planes to form a limiting structure. Before the front and rear mold inserts have finished moving out, the limiting structure limits and fixes the slider seat. When the front and rear mold inserts have finished moving out, the limiting structure does not hinder the slider seat from being pulled out, thereby reducing the risk of damage to the front and rear mold inserts.

[0040] 2. This utility model sets the length relationship between the first limiting abutment plane and the second limiting abutment plane, and creates a gap between the inclined guide post and the inclined inner sidewall of the inclined guide hole. This ensures that before the mold opens to a certain distance, the first limiting abutment plane and the second limiting abutment plane are always in contact, limiting the slider seat. Furthermore, the inclined guide post does not contact the inclined inner sidewall, so that the inclined guide post moving along the mold opening direction has no driving force on the slider seat. This distance can be determined according to the need for the front and rear inserts to achieve complete clearance. That is, before complete clearance, it is always in a limited state and has no driving force on the slider seat. After the mold opens to a certain distance, because the front and rear inserts have achieved complete clearance, the inclined guide post contacts the inclined inner sidewall. The slider seat can then be further driven by the inclined guide post moving along the mold opening direction. The slider seat drives the slider insert, realizing the extraction of the slider insert. This reduces the risk of damage to the front and rear mold inserts, and simultaneously realizes the clearance of the front and rear mold inserts and the extraction of the slider insert through the mold opening operation, saving time and effort.

[0072] The injection mold equipment also includes: a mold opening mechanism assembly; the mold opening mechanism assembly includes: a tie rod cylinder 8, a limiting pin 9, and an outer sleeve 18; the tie rod cylinder 8 is mounted on the front mold plate 10, and the outer sleeve 18 is mounted on the rear mold plate 11; one end of the tie rod cylinder 8 passes through the outer sleeve 18 and forms a limiting end 801 that abuts against the outer sleeve 18, the limiting end 801 can be compressed into the outer sleeve 18 and move within the outer sleeve 18; the rear mold plate 11 is provided with the limiting pin 9, and the rear mold support plate 12 is provided with a limiting element 1201 that can block the movement of the limiting pin 9.

[0073] Working principle:

[0074] like Figure 5 As shown, when the mold is not opened, the first limiting abutment plane 101 and the second limiting abutment plane 301 are in abutment state, which limits and fixes the slider seat 3.

[0075] During mold opening, the tie rod cylinder 8 is pulled upwards. Due to the presence of the limiting end 801, the limiting end 801 generates a traction force on the outer sleeve 18, which in turn drives the front mold plate 10 and the rear mold plate 11 to move upwards together, opening the PL1 surface. At this time, the rear mold support plate 12 remains stationary. Since the rear mold insert 6 is installed on the rear mold support plate 12 and the rear mold core 17 is installed on the rear mold plate 11, the rear mold core 17 moves after the mold plate 11, while the rear mold insert 6 remains stationary. Relative movement occurs between the rear mold core 17 and the rear mold insert 6, and the rear mold insert 6 makes way from the slider insert 4. During this process, since the front mold plate 10 and the rear mold plate 11 move together, there is no relative movement between the front mold plate 10, the rear mold plate 11, the shovel 1 on the front mold plate 10, the slider seat 3 on the rear mold plate 11, and the inclined guide post 7 on the front mold plate 10.

[0076] When the pull rod cylinder 8 is pulled upward a certain distance, the limit pin 9 reaches the position of the limit piece 1201 and is fixed. Because the limit pin 9 is connected to the rear template 11, the rear template 11 is also fixed. The outer sleeve 18 inside the rear template 11 does not move. At this time, the pull rod cylinder 8, the front template 10, the front mold core 16, and the front mold insert 5 continue to move upward. The limit end 801 of the pull rod cylinder 8 will be compressed into the outer sleeve 18 and move upward within the outer sleeve 18. The front template 10 drives the shovel 1 to move upward. Because the slider seat 3 is installed on the rear template 11, the slider seat 3 is in a stationary state. Relative movement occurs between the shovel 1 and the slider seat 3. The first limit abutment plane 101 and the second limit abutment plane 301 begin to move relative to each other.

[0077] The front template 10 will simultaneously drive the inclined guide post 7 to move upward, but because there is a gap between the inclined guide post 7 and the inclined inner wall 304 of the inclined guide hole 303, such as Figure 7 As shown in D, the gap between the inclined guide post 7 and the inclined inner wall 304 is such that no driving force is generated on the slider seat 3 before the inclined guide post 7 contacts the inclined inner wall 304.

[0078] During the upward movement, the front mold insert 5 moves away from the slider insert 4. As the first limiting abutment plane 101 moves a certain distance on the second limiting abutment plane 301, the upper edge of the first inclined surface 102 reaches the lower edge of the second inclined surface 302, and the front mold insert 5 completes the relocation. At this time, the shovel 1 no longer has a limiting effect on the slider seat 3. The shovel 1 continues to move upward, and at the same time, the inclined guide post 7 contacts the inclined inner side wall 304, which begins to generate driving force on the slider seat 3, driving the slider seat 3 to be pulled out.

[0079] In this embodiment, delayed core pulling refers to delaying the core pulling of the slider seat 3 relative to the relocation of the front mold insert 5 and the rear mold insert 6, after the front mold insert 5 and the rear mold insert 6 have relocated from the slider insert 4.

[0080] In this embodiment, the front mold insert 5 is installed in the front mold core 16, and the front mold core 16 is installed in the front template 10. The rear mold insert 6 is installed in the rear mold core 17, while the slider seat 3 and the slider insert 4 are installed in the rear template 11.

[0081] The front template 10, the rear template 11, and the rear mold support plate 12 are connected by the guide post 14, the rear template guide sleeve 15, and the front template guide sleeve 13 to position the mold frame and guide it when the mold frame is opened and closed, ensuring that the mold structure parts have a relatively accurate positional relationship when the mold is produced and opened and closed.

[0082] like Figure 3 As shown in Part A of the diagram, the front mold insert 5 and the rear mold insert 6 clamp the slider insert 4 on the upper and lower sides. The three parts must be pulled out in a specific order. The front mold insert 5 and the rear mold insert 6 must be pulled out first to make room before the slider insert 4 can be pulled out. If the slider insert 4 is pulled out first, it will damage the front mold insert 5 and the rear mold insert 6.

[0083] The innovative aspect of this embodiment is the addition of two limiting contact surfaces at the relative positions of the shovel 1 and the sliding block 3, such as... Figure 3 At the position indicated by B, both limiting contact surfaces are straight. During the mold opening process, the straight surfaces can lock the slider seat 3 in place, ensuring that the slider can only be pulled out after the front mold insert 5 and the rear mold insert 6 are completely removed. This ensures safe production of the special structural sequence of mold opening and reduces the risk of insert breakage.

[0084] Compared to conventional structures, where the slider requires a hydraulic cylinder for core pulling, and the cylinder pulls the core after the mold is fully opened, the structure is cumbersome, the mold layout is large, and the cost is high. The structure of this embodiment is safe, reliable, and cost-effective.

[0085] When the mold is opened by the side pull of the injection molding machine, the rear template 11, the rear mold support plate 12 and the entire rear mold are opened. Because the front template 10 is pulled by the pull rod cylinder 8 of the mold opening mechanism assembly and limited by the middle limit pin 9, the outer sleeve 18 will be strongly pulled. The outer sleeve 18 will drive the rear template 11 and the slider seat 3 to move.

[0086] The slider insert 4 moves upward as a whole, the PL1 parting surface opens first, and the rear mold insert 6 is installed on the rear mold support plate 12. When the PL1 parting surface opens first, the rear mold insert 6 of the rear mold is pulled down, and the interference structure of the slider insert 4 of the rear mold is disengaged, that is, it is disengaged from the rear mold insert 6. When the PL1 parting surface continues to open, until the limit pin 9 reaches the preset position and is limited, the pull rod cylinder 8 is pulled strongly, and the limit end 801 of the pull rod cylinder 8 can retract inward and into the outer sleeve 18. The PL1 parting surface stops, and the PL2 parting surface opens. During the opening process of the PL2 parting surface, the inclined guide post 7 Installed on the front template 10, there is a gap between the inner wall of the hollow cavity of the inclined guide post 7 and the slider seat 3. The gap size and the length of the lower end of the shovel 1 are related by a trigonometric function. That is, the lower end of the shovel 1 first stops the slider seat from moving. After the front mold insert 5 is pulled out, when the lower end of the shovel 1 moves to the second inclined surface 302 position of the slider seat 3, the inclined guide post 7 contacts the side wall of the inclined guide post hole 303 of the slider seat 3, so that the slider seat 3 and the slider insert 4 can be pulled out, preventing the front mold insert 5 and the slider insert 4 from interfering with each other and ensuring the safety of the mold operation.

[0087] This utility model sets two abutting planes to form a limiting structure. Before the front and rear mold inserts have finished moving out, the limiting structure limits and fixes the slider seat. When the front and rear mold inserts have finished moving out, the limiting structure does not hinder the slider seat from being pulled out.
