Description

Technical Field

[0001] This invention relates to the field of injection molds, and in particular to an injection mold with a slanted ejector linkage slider. Background Technology

[0002] In injection molding, such as Figure 11 and Figure 12 In the case of the ventilator housing shown, due to its thin wall thickness and relatively high height, as well as the gradually tapering undercut section at the top, the sliding mechanism and the angled ejector mechanism are both quite tall and large. Because the height and volume of the sliding mechanism and the angled ejector mechanism exceed the specifications, and the mold opening space is limited, the ends of multiple angled ejectors furthest from the rear mold will interfere with each other during mold opening. This restricts the opening stroke of the angled ejectors, resulting in the problem that the upper part of the ventilator housing and its undercut section cannot be fully demolded.

Detailed Implementation

[0017] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0018] It should be noted that, in this invention, unless otherwise stated, when an element is referred to as "connected to" or "disposed on" another element, it can be directly on the other element or may have an intervening element present simultaneously. "Inner" and "outer" refer to the inner and outer contours of a specific part. "Far" and "near" refer to the far and near relative to a certain component.

[0019] like Figures 1-10 As shown in the figure, an injection mold for a slanted top linkage slider provided in one embodiment of the present invention includes: Front mold 1, the front mold 1 moves in the first direction to open; Rear template 2, wherein the rear template 2 is provided with a core 3; A sliding mechanism for forming the outer wall of a product, the sliding mechanism being slidably connected to the rear template 2 along a second direction, the second direction being perpendicular to the first direction; A direct ejection mechanism includes an ejector plate, a straight ejector rod 9, and an ejector component arranged around a core 3. The rear mold plate is distributed between the ejector plate and the front mold 1. The straight ejector rod 9 is slidably connected to the core 3, and its two ends are respectively fixed to the ejector plate and the front mold 1. The ejector component is slidably connected to the rear mold plate 2. One end of the ejector component is fixed to the ejector plate, and the other end of the ejector component forms a forming surface for forming the bottom surface of the product. The sliding directions of the ejector plate, the straight ejector rod 9, and the ejector component all extend along a first direction. A plurality of inclined ejector mechanisms are distributed around the straight ejector rod 9. The inclined ejector mechanism includes an inclined ejector head 12 for forming the inner wall of the product and a sliding component 13 for forming the undercut of the product. The inclined ejector head 12 is slidably connected to the core 3 along a third direction, and the third direction is inclined to intersect the first direction. The sliding component 13 is slidably connected to the core 3 along the first direction. The sliding component 13 is distributed between the inclined ejector head 12 and the front mold 1. The sliding component 13 is slidably connected to the inclined ejector head 12. The sliding component 13 slides relative to the inclined ejector head 12 along a second direction. During mold closing, the sliding mechanism is distributed on the movement path of the ejector component, and the sliding mechanism generates pressure that hinders the movement of the ejector component.

[0020] like Figures 6-7As shown, the sliding component 13 includes a base plate 131 and two guide posts 132. The two guide posts 132 are detachably connected to both ends of the base plate 131. Both guide posts 132 are slidably connected to the core 3. The angled head 12 is distributed between the two guide posts 132. The base plate 131 is constructed with an arc-shaped curved surface for forming the inverted product. The angled head 12 is provided with a T-shaped slider 133. The base plate 131 is constructed with a T-shaped groove along a second direction. The T-shaped slider 133 is slidably connected inside the T-shaped groove. Both guide posts 132 extend along a first direction and guide the sliding direction of the base plate 131 through the guide posts 132, so that the base plate 131 moves relative to the core 3 along the first direction. The T-shaped slider 133 connects the base plate 131 and the angled head 12, so that the angled head 12 and the base plate 131 always remain in contact, preventing the base plate 131 from detaching from the angled head 12.

[0021] The front mold 1 has several vertical straight channels. A cavity is formed between the sliding mechanism and the inclined ejector 12. The sliding mechanism and the sliding component 13 are opposite to each other. The surface of the base plate 131 away from the inclined ejector 12 is constructed with a branch channel 134 that communicates with the cavity. The vertical straight channels and the branch channels 134 correspond one-to-one and are interconnected. Molten material flows into the branch channels 134 on the sliding component 13 through the vertical straight channels and is injected into the cavity through the branch channels 134. When the moving component and the ejector component generate relative displacement, the sprue is automatically cut off. No runner plate is required, simplifying the mold structure.

[0022] The inclined ejector mechanism further includes an inclined ejector rod 14, a slide block 15, and an inclined ejector guide bar 16. The inclined ejector guide bar 16 is detachably connected to one end of the core 3 near the front mold 1. One end of the inclined ejector head 12 is detachably connected to the inclined ejector rod 14, and the other end of the inclined ejector head 12 has a second slide groove along a third direction. The inclined ejector guide bar 16 is slidably connected to the second slide groove. The inclined ejector rod 14 is slidably connected to the core 3 along a third direction, and the inclined ejector rod 14 is slidably connected to the slide block 15 along a second direction. The slide block 15 is detachably connected to the ejector plate. The inclined ejector head 12, the inclined ejector rod 14, the slide block 15, and the lower ejector plate 7 are connected in sequence, and the lower ejector plate 7 drives the inclined ejector head 12 and the sliding component 13 to open the mold.

[0023] The ejector plate includes a sequential mold opening structure 8, an upper ejector plate 5, a middle ejector plate 6, a lower ejector plate 7, and a central ejector pin for ejecting the product. The middle ejector plate 6 is distributed between the upper ejector plate 5 and the lower ejector plate 7. The upper ejector plate 5 and the rear mold plate 2 are opposite to each other. The middle ejector plate 6 is fixedly connected to the upper ejector plate 5. The central ejector pin is connected to the upper ejector plate 5. The straight ejector pin 9 is connected to the middle ejector plate 6. The middle ejector plate 6 and the lower ejector plate 7 are connected through the sequential mold opening structure 8. The two ends of the central ejector pin are respectively connected to the center positions of the cavity of the middle ejector plate 6 and the front mold 1. The slide 15 passes through the upper ejector plate 5 and the middle ejector plate 6, and the slide 15 is detachably connected to the lower ejector plate 7. The upper ejector plate 5 or the middle ejector plate 6 is driven by an external hydraulic cylinder to open the mold.

[0024] The inclined ejector head 12, inclined ejector rod 14, slide block 15, and lower ejector plate 7 are connected in sequence. The lower ejector plate 7 drives the inclined ejector head 12 and sliding component 13 to open the mold. The upper ejector plate 5 and middle ejector plate 6 drive the ejector component, middle ejector rod, and front mold 1 to open the mold synchronously. In the early stage of mold opening, the middle ejector rod drives the front mold 1 to demold from the product. In the later stage of mold opening, the middle ejector rod drives the sliding mechanism and the product to completely move away from the cavity. Furthermore, the relative movement between the front mold 1 and the rear mold plate 2 drives the sliding mechanism away from the inclined ejector head 12, thus realizing the product mold opening.

[0025] The inclined ejector mechanism also includes a fixing block and a first spring. The fixing block is detachably connected to the surface of the inclined ejector head 12 near the front mold 1. The two ends of the first spring respectively abut against the base plate 131 and the fixing block, and the first spring generates a spring force to drive the base plate 131 away from the fixing block. When the inclined ejector head 12 is demolded from the product and the sequential mold opening structure 8 is not yet unlocked, the spring force generated by the first spring drives the base plate 131 of the sliding component 13 towards the undercut position of the product, so that the base plate 131 and the undercut position of the product remain in contact. After the sequential mold opening structure 8 is unlocked, the upper ejector plate 5 and the middle ejector plate 6 drive the straight ejector rod 9 and the ejector component to move, and the ejector component drives the undercut position of the product to disengage from the base plate 131.

[0026] like Figure 5 As shown, the ejector component includes several connecting rods 10 and several ejector inserts 11. The ejector inserts 11 are arranged in a ring around the core 3, with their ends connected end to end. The connecting rods 10 are evenly spaced around the core 3 and are slidably connected to the rear template 2. The two ends of the connecting rods 10 are respectively connected to the ejector inserts 11 and the middle ejector plate 6. The upper ejector plate 5, the middle ejector plate 6, the straight ejector rod 9, and the ejector component are fixedly connected in sequence. The upper ejector plate 5, the middle ejector plate 6, the straight ejector rod 9, and the ejector component will move synchronously. After the lower ejector plate 7, the angled ejector head 12, and the base plate 131 are in place and stop moving, the ejector component drives the undercut position of the product to demold from the base plate 131.

[0027] like Figure 8 As shown, the sliding mechanism includes a sliding seat 17, a lower guide component 19, and an upper guide component 18. The front mold 1 has a cavity for accommodating the sliding mechanism, the inclined ejector mechanism, and the core 3. Both the lower guide component 19 and the upper guide component 18 are connected to the inner wall of the cavity. The lower guide component 19 is distributed on the side of the upper guide component 18 near the rear mold plate 2. The sliding seat 17 has a third groove extending in a third direction at one end near the rear mold plate 2, and a guide hole extending in a third direction at one end near the front mold 1. The lower guide component 19 is slidably connected to the third groove, and the upper guide component 18 is slidably connected to the guide hole. The lower guide component 19 guides the lower end of the sliding seat 17, driving the lower end of the sliding seat 17 to move in a second direction. The upper guide component 18 guides the upper end of the sliding seat 17, driving the upper end of the sliding seat 17 to move in the second direction. To improve the stability of the slide seat 17 during mold opening and avoid instability caused by the slide seat 17's own volume during mold opening.

[0028] The upper guide component 18 includes an inclined guide post 132 and a second spring sleeved on the inclined guide post 132. The two ends of the second spring respectively abut against the inner wall of the cavity and the inner wall of the guide hole. The lower guide component 19 includes a base and a guide rail fixed to the side of the base. The guide rail extends in a third direction and is slidably connected to the inside of the third slide groove. The upper end of the slide seat 17 is driven to open the mold by the inclined guide post 132, and the lower end of the slide seat 17 is driven to open the mold by the guide rail.

[0029] like Figures 9-10 As shown, the sequential mold opening structure 8 includes a rear mold base 4, a fixing rod 20, a fixing seat 21, a locking block 22, and a third spring 23. The rear mold base 4 is connected to the rear template 2, and the ejector plate is distributed between the rear template 2 and the rear mold base 4. One end of the fixing rod 20 is fixed to the rear mold base 4, and the other end of the fixing rod 20 has a first inclined surface. The fixing seat 21 is fixed to the lower ejector plate 7, and the fixing rod 20 slidably passes through the fixing seat 21. The fixing seat 21 has a locking groove, and one end of the locking block 22 is loosely connected to the inside of the locking groove. The other end of the locking block 22 is slidably connected to the middle ejector plate 6 along a second direction. The third spring 23 generates a spring force to drive the locking block 22 away from the middle ejector plate 6. The locking block 22 has a second inclined surface that is inclined towards the rear mold base 4, and the second inclined surface is opposite to the first inclined surface. The fixing seat 21 has a through groove through which the fixing rod 20 passes, and the projection of the second inclined surface along the first direction is distributed inside the through groove.

[0030] When the sequential mold opening structure 8 is in the locked state, the locking block 22 is embedded inside the slot, with its end face abutting against the side wall of the slot. The second inclined surface is located inside the through groove, and the locking block 22 drives the fixed seat 21 to move synchronously. When the locking block 22 moves to the point where the first inclined surface contacts the second inclined surface, the first and second inclined surfaces engage, and the second inclined surface guides the locking block 22 to move away from the fixed rod 20 and toward the central ejector plate 6, causing the locking block 22 to disengage from the slot, and the sequential mold opening structure 8 enters the unlocked state. In the unlocked state, the central ejector plate 6 separates from the lower ejector plate 7, the inclined ejector head 12 and the sliding component 13 are relatively stationary, and there is relative movement between the inclined ejector head 12 and the ejector component.

[0031] This mold is preferably used in a horizontal injection molding machine. During the mold opening movement, the middle ejector plate 6 moves synchronously with the upper ejector plate 5. The relative positions of the middle ejector plate 6 and the lower ejector plate 7 are locked by the sequential mold opening structure 8. The middle ejector plate 6 drives the lower ejector plate 7 to move synchronously through the sequential mold opening structure 8.

[0032] The upper ejector plate 5 and the middle ejector plate 6 are displaced, driving the ejector rod to move synchronously. The ejector rod drives the front mold 1 away from the rear mold plate 2 to open the mold. The mold opening movement of the front mold 1 drives the sliding mechanism to move along the second direction to open the mold. When the sliding mechanism opens the mold, it moves away from the base plate 131 of the inclined ejector head 12 and the sliding component 13, causing the outer wall of the product to separate from the sliding mechanism.

[0033] In the initial stage of mold opening, the distance between the sliding mechanism and the inclined ejector head 12 is less than the width of the product undercut, and the product cannot be ejected between the sliding mechanism and the inclined ejector head 12. At this time, the front mold 1 will gradually move away from the sliding mechanism and the product under the action of the middle ejector pin, so as to achieve product demolding from the cavity.

[0034] The displacement of the ejector plate 6 drives the straight ejector rod 9 to move synchronously. The ejector component follows the displacement of the straight ejector rod 9 to lift the bottom surface of the product, causing the inner wall of the product to separate from the core 3.

[0035] The lower ejector plate 7 displaces and drives the inclined ejector head 12 to open the mold along a third direction. Simultaneously, the inclined ejector head 12 pushes the base plate 131 of the sliding component 13 towards the front mold 1, causing the base plate 131 of the sliding component 13 to open the mold along a first direction, resulting in relative movement between the inclined ejector head 12 and the base plate 131 of the sliding component 13. The base plate 131 supports and drives the product to continue moving and opening the mold, causing the inner wall of the product to contact the inclined ejector head 12.

[0036] After the angled ejector head 12 moves to the preset position, the locking block 22 contacts the first inclined surface at the end of the fixing rod 20, causing the locking block 22 to disengage from the slot. The sequential mold opening structure 8 unlocks, and the middle ejector plate 6 separates from the lower ejector plate 7. Both the lower ejector plate 7 and the angled ejector head 12 remain stationary, while the middle ejector plate 6 continues to move following the upper ejector plate 5. When the base plate 131 stops moving, the ejector component continues to move, pushing the product to displace it, causing the product to disengage from the base plate 131. This completes the mold opening action and allows for successful demolding.

[0037] The technical features of the embodiments described above can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these should all be considered to be within the scope of this specification.
