[0001] The invention relates to the technical field of production of crumb collecting trays for pet drying boxes, in particular to an injection molding device for a detachable crumb collecting tray for a pet drying box. Background Art

[0002] As a core functional component, the plastic tray of the pet drying box needs to meet the dual needs of pet carrying and drying ventilation. According to the differences in material properties (such as PP, ABS, etc.), its injection molding temperature usually needs to be controlled within the range of 200-300℃.

[0003] With the upgrading of consumption and the innovation of pet-raising concepts, traditional processes usually adopt fixed thickness design, but the current market has put forward higher-dimensional requirements for product performance: High-end scenarios: When using high-cost materials (such as glass fiber reinforced PP), lightweighting can be achieved by reducing the thickness (2-3mm), while relying on the high strength and aging resistance of the material itself to meet performance requirements; Economic scenario: When using low-cost materials (such as ordinary PP), the thickness needs to be increased (4-5mm) to compensate for the difference in material properties and ensure the load-bearing capacity; Traditional solutions rely on multiple sets of mold groups to switch production to complete the thickness adjustment of the parts, resulting in high equipment investment and low mold change efficiency, which is a heavy burden especially for small and medium-sized factories; In the prior art, although the size of the mold cavity can be changed by changing the height of the support plate inside the movable mold to achieve the adjustment of the tray thickness, in actual application, when the support plate is changed, it will produce greater friction with the movable mold, resulting in reduced sealing. In addition, as the height of the support plate inside the movable mold changes, when the support plate is close to the top or bottom, the movable mold and the support plate form a cantilever, causing the movable mold to be unevenly stressed and deformed, thereby causing reduced sealing performance and leakage. Summary of the invention

[0004] The object of the present invention is to provide an injection molding device for a detachable crumb collecting tray of a pet drying box to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: an injection molding device for a detachable crumb collecting tray of a pet drying box, comprising a fixed mold and a movable mold, wherein the fixed mold is provided with a plurality of cores, and the movable mold is opened and closed by a driving assembly, and the movable mold comprises: The housing is arranged directly above the fixed mold and is raised and lowered by the driving assembly; The forming plate is located between the fixed mold and the shell, and the height of the mold cavity is adjusted by a first telescopic member connected to the shell.

A second telescopic member is fixedly connected between the two front and rear side panels and the shell. When the second telescopic member pushes the front and rear side panels to slide along the shell until the rollers are disengaged from the left and right side panels, the springs will respectively push the left and right side panels to slide to the left and right sides to separate from the shell.

[0009] As a further solution of the present invention, an adjustment component is also included above the core, and the adjustment component includes: A plurality of laterally distributed positioning rods are provided between the shell and the forming plate; A plurality of positioning members are arranged on each positioning rod, and the core array is connected below the positioning members; When the first telescopic member drives the forming plate to move, the core slides relative to the forming plate and maintains contact with the inner cavity of the fixed mold.

[0010] As a further solution of the present invention, the positioning members are all slidably connected to the positioning rod.

[0011] As a further solution of the present invention, the positioning rod is slidably connected to the housing, and a third telescopic member is provided between the two; The forming plate is provided with a plurality of lifting rods distributed in an array, and each lifting rod is connected to the forming plate via a fourth telescopic member; A conical first clamping plate and a second clamping plate are slidably connected to the middle of each lifting rod, and the two clamping plates cooperate with the receiving groove on the forming plate; The first clamping plate and the second clamping plate are connected with a guide member, and the guide member is provided with a guide groove with a vertical bottom and an inclined top; Contact wheels are arranged on both sides of the core, and the contact wheels are rotatably connected with the lifting rod.

DETAILED DESCRIPTION

[0019] See also Figure 1-Figure 21 The present invention provides a technical solution: an injection molding device for a detachable crumb collection tray of a pet drying box, comprising a fixed mold 1 and a movable mold 2, wherein the fixed mold 1 is provided with a plurality of cores 11, the movable mold 2 is opened and closed by a driving assembly, the movable mold 2 comprises a shell 3, a molding plate 4, a first telescopic member 501, a side plate 5, a separation assembly and a stress adjustment member, the shell 3 is arranged directly above the fixed mold 1 and is lifted and lowered by the driving assembly, the molding plate 4 is located between the fixed mold 1 and the shell 3, the height adjustment of the mold cavity is achieved by the first telescopic member 501 connected to the shell 3, the core 11 penetrates the molding plate 4 and is slidably connected thereto, a plurality of side plates 5 are provided and are all slidably connected to the shell 3, the plurality of side plates 5 are used to seal the side of the shell 3 when docked, and the separation assembly is used to control the simultaneous separation or docking of the side plates 5 and the shell 3; The stress adjusting member is slidably connected to the side plate 5 and is used to achieve stress adjustment when the forming plate 4 is adjusted in height.

[0020] The stress adjustment member includes a support rod 6 slidably connected to the side plate 5, the support rod 6 is slidably connected to the insertion rod 401, the insertion rod 401 is slidably connected to the inside of the side plate 5 and its bottom is fixedly connected to the forming plate 4 like Figure 1-Figure 5 , Figure 7 , Figure 10-12 As shown: The separation component controls the four side plates 5 to fit to the housing 3 to form the movable mold 2, and the driving component controls the relative movement of the movable mold 2 and the fixed mold 1 to complete mold opening and mold closing; When the four side plates 5 are fitted with the housing 3, the housing 3 and the molding plate 4 can be clamped and sealed. After the driving assembly controls the movable mold 2 and the fixed mold 1 to close the mold, an injection cavity 24 is formed between the molding plate 4 and the inner cavity of the fixed mold 1 for injection molding. Figure 1 The chip collecting tray 26 inside the drying box 25 shown is mass-produced; When the height of the injection cavity 24 is adjusted, the thickness of the workpiece (chip collection tray 26) can be adjusted; The adjustment works as follows: First, the four side plates 5 are controlled by the separation component to move around the shell body 3 and the forming plate 4 to complete the separation of the movable mold 2, so as to avoid large wear between the forming plate 4 and the side plates 5 when the height is adjusted. When the four side plates 5 are separated along the shell body 3, they will slide along the shell body 3 and drive the four support rods 6 to slide along the insertion rod 401. After the side plates 5 are separated from the forming plate 4, the first telescopic member 501 is controlled to shorten (the first telescopic member 501 is an electric push rod or cylinder that can be wirelessly controlled in the prior art, which can be telescopically controlled by a wireless remote controller, and the installation and arrangement are conventional settings, which will not be described in detail) to drive the forming plate 4 to rise vertically relative to the fixed mold 1 and slide up relative to the multiple cores 11. At this time, the distance between the bottom of the forming plate 4 and the inner cavity of the fixed mold 1 changes, and the bottom of the core 11 is always in contact with the inner cavity of the fixed mold 1, so that the height between the injection cavities 24 is increased, and the thickness of the product can be changed when the product is produced later; During the rising process of the forming plate 4, the insertion rod 401 will slide along the inside of the four side plates 5, and drive the four support rods 6 to slide up from the side walls of the side plates 5, so that the support rods 6 can continue to remain on one side around the forming plate 4; After the adjustment work is completed, the four side plates 5 are controlled by the separation component to move to fit and clamp the shell 3 and the forming plate 4. After the side plates 5, the shell 3, and the forming plate 4 form the movable mold 2, the driving component can be used to drive the movable mold 2 to close the fixed mold 1 to produce the product; In order to ensure the sealing of the movable mold 2, the separation component drives the four side plates 5 to fit with the shell 3 and the forming plate 4, which will act on the forming plate 4 with a large extrusion force. The extrusion force is applied from the side plate 5 to the forming plate 4. In particular, when the forming plate 4 is close to the top or bottom of the side plate 5 (that is, far away from the middle of the side plate 5), it is more likely to cause the side plate 5 to deform, which in turn easily leads to a shortened life of the side plate 5 and a reduced sealing after multiple uses of the forming plate 4. The present invention cooperates with the insert rod 401 and the support rod 6. When the forming plate 4 is moved by the first telescopic member 501, the insert rod 401 can drive the support rod 6 to slide along the side wall of the side plate 5, so that the support rod 6 can move with the forming plate 4, and then when the side plate 5 clamps the shell 3 and the forming plate 4, the support rod 6 located on one side of the side plate 5 and capable of synchronously following the lifting of the forming plate 4 provides support. When the side plate 5 squeezes the forming plate 4, the stress point changes due to the height change of the forming plate 4, so that the support point changes synchronously, and then the side plate 5 provides protection when squeezing the forming plate 4, avoiding deformation of the side plate 5, making the forming plate 4 evenly stressed after the height is adjusted, and improving the service life of the mold in the process of completing the thickness adjustment of the workpiece. In the present invention, when the molding plate 4 moves for height adjustment, the support rod 6 is adjusted to a new stress point in real time, so that the pressure of the side plate 5 on the molding plate 4 is evenly distributed. The dynamic balance system formed by the insertion rod 401 and the support rod 6 causes the extrusion stress of the side plate 5 on the molding plate 4 to change with the height change, so as to avoid deformation of the side plate 5 and leakage of material when the height of the molding plate 4 relative to the side plate 5 changes. When the four side plates 5 are molded, the height change of the molding plate 4 is automatically compensated and the sealing is completed. When producing parts with different thicknesses, there is no need to replace the template.

[0021] As a further solution of the present invention, the four side panels 5 are all provided with an integral reinforcing rib 7 , and the four support rods 6 form sliding pairs with the four reinforcing ribs 7 respectively.

[0022] like Figure 2-5 and Figure 7-Figure 9 As shown: By providing the reinforcing ribs 7 , the insert rods 401 will drive the support rods 6 to slide along the reinforcing ribs 7 during the height adjustment of the forming plate 4 . The reinforcing ribs 7 are provided to help enhance the stability of the side plate 5 .

[0023] As a further solution of the present invention, the separation component includes rollers 8 rotatably connected to the side walls of the front and rear side panels 5 and springs 9 mounted on the sliding shafts of the two side panels 5 in the left and right directions. A second telescopic member 10 is fixedly connected between the two front and rear side panels 5 and the shell 3. When the second telescopic member 10 pushes the front and rear side panels 5 to slide along the shell 3 until the rollers 8 are disengaged from the left and right side panels 5, the springs 9 will respectively push the left and right side panels 5 to slide to the left and right sides to separate from the shell 3.

[0024] like Figure 4-Figure 5 as well as Figure 7-Figure 9 As shown: The extension and contraction of the second telescopic member 10 drives the front and rear side panels 5 and the reinforcing ribs 7 to move forward and backward, and drives the rollers 8 to move. When the rollers 8 move to the point where they are out of contact with the reinforcing ribs 7 on the other two sides, the springs 9 push the side panels 5 on the other two sides to slide along the shell 3. At this time, the four side panels 5 are separated from the shell 3 and the forming plate 4. At this time, the height of the forming plate 4 is adjusted. When the adjustment is completed, the second telescopic member 10 pulls the front and rear side panels 5 to move toward the shell 3. Figure 8 As shown, when all four side panels 5 are separated from the shell 3, the displacement distance of the two side panels 5 in the front-to-back direction is longer than that of the two side panels 5 in the left-to-right direction, and at this time, the two side panels 5 in the left-to-right direction are within the trajectory range of the roller 8 moving forward and backward. When the roller 8 moves to contact the side panels 5 in the left-to-right direction, it will push them to fit tightly against the shell 3 first, and then the second telescopic member 10 continues to shorten to move the roller 8 along the reinforcing ribs 7 on the side panels 5 in the left-to-right direction, so as to keep them in contact with the shell 3 (as shown in FIG. Fig. 9 As shown), until the side panels 5 in the front-to-back direction are fitted with the shell 3, the side panels 5 in the left-to-right direction, the shell 3 and the forming plate 4 are clamped and sealed at the same time.

[0025] As a further solution of the present invention, an adjustment component is also included above the core 11, and the adjustment component includes: A plurality of laterally distributed positioning rods 12 are provided between the housing 3 and the forming plate 4; A plurality of positioning members 13 are provided on each positioning rod 12, and an array of cores 11 is connected below the positioning members 13; When the first telescopic member 501 drives the forming plate 4 to move, the core 11 slides relative to the forming plate 4 and maintains contact with the inner cavity of the fixed mold 1 .

[0026] like Figure 3 , Figure 12-13 As shown: When the height of the forming plate 4 is adjusted, the positioning rod 12 and the positioning member 13 remain stationary relative to the forming plate 4 to limit the core 11, and then the forming plate 4 rises to slide along the core 11, so that the bottom end of the core 11 continues to fit with the inner cavity of the fixed mold 1.

[0027] As a further solution of the present invention, the positioning members 13 are all slidably connected to the positioning rods 12 .

[0028] like Figure 12-13 As shown: When the core 11 is in an inclined state, the ventilation holes on the workpiece are inclined, and the positioning rod 12 continues to remain stationary when the height of the forming plate 4 is adjusted. At this time, the forming plate 4 rises and forces the core 11 to drive the positioning member 13 to slide along the positioning rod 12 through friction with the core 11, so that the bottom of the core 11 still remains in contact with the inner cavity of the fixed mold 1 when the core 11 is inclined.

[0029] As a further solution of the present invention, the positioning rod 12 is slidably connected to the housing 3, and a third telescopic member 22 is provided between the two; A plurality of lifting rods 14 distributed in an array are provided on the forming plate 4, and each lifting rod 14 is connected to the forming plate 4 via a fourth telescopic member 15; A conical first clamping plate 16 and a second clamping plate 17 are slidably connected to the middle of each lifting rod 14, and the two clamping plates cooperate with the receiving groove 18 on the forming plate 4; The first clamping plate 16 and the second clamping plate 17 are connected with a guide member 19, and the guide member 19 is provided with a guide groove 20 with a vertical bottom and an inclined top; Contact wheels 21 are provided on both sides of the core 11 , and the contact wheels 21 are rotatably connected to the lifting rod 14 .

[0030] As a further solution of the present invention, the first clamping plate 16 and the second clamping plate 17 are both tapered.

[0031] like Figure 12-Figure 21 As shown: like Fig.18 As shown, before the height of the molding plate 4 is adjusted, the height of the injection cavity 24 is L1 (i.e., the distance between the molding plate 4 and the inner cavity of the fixed mold 1), and the distance between the positioning rod 12 and the molding plate 4 is L2, and then the fourth telescopic member 15 and the third telescopic member 22 are extended and shortened respectively, at this time, the positioning rod 12 and the lifting rod 14 contact wheel 21 rise synchronously when the molding plate 4 is stationary, and when the rising distance is L0, the lifting rod 14 will drive the first clamping plate 16 and the second clamping plate 17 to slide along the guide groove 20 provided on the guide member 19 when it rises, and when the first clamping plate 16 and the second clamping plate 17 are in the vertical part of the guide groove 20 and slide, the first clamping plate 16 and the second clamping plate 17 with a conical bottom will keep clamping the core 11 and rise straightly along the accommodating groove 18, thereby avoiding friction between the core 11 and the accommodating groove 18, and at this time, the core 11 will rise relative to the molding plate 4, thereby avoiding direct friction with the molding plate 4; When the first clamping plate 16 and the second clamping plate 17 slide to the inclined portion above the guide groove 20, the first clamping plate 16 and the second clamping plate 17 are guided by the inclined portion to slide to both sides along the lifting rod 14, thereby separating the first clamping plate 16 and the second clamping plate 17 from the core 11. Fig.19As shown, when the positioning rod 12 rises to a distance of L0, the distance between the bottom of the core 11 and the fixed mold 1 is L0, and the distance between the molding plate 4 and the fixed mold 1 is still L1. When the positioning rod 12 rises, the distance between the positioning rod 12 and the molding plate 4 is L1+L0; At this time, the first telescopic member 501 can be used to drive the forming plate 4 to rise to adjust the height. When the forming plate 4 rises a distance, the forming plate 4 drives the lifting rod 14, the first clamping plate 16, the second clamping plate 17, the contact wheel 21 and the guide member 19 to rise synchronously relative to the core 11, and the contact wheel 21 provides support for both sides of the core 11 while pushing the core 11 and the positioning member 13 to slide along the positioning rod 12. The distance between the forming plate 4 and the positioning rod 12 is (L2+L0)-a (such as Fig. 20 As shown in FIG. 1 , the distance between the molding plate 4 and the inner cavity of the fixed mold 1 is L1+a, but the distance between the core 11 and the inner cavity of the fixed mold 1 is still L0. When the contact wheel 21 rises relative to the core 11, it slides along the surface of the core 11 and pushes the core 11 and the positioning member 13 to slide along the positioning rod 12, so that when the molding plate 4 changes in height relative to the core 11, the core 11 can adapt to the change of the molding plate 4. like Fig.21 As shown, after the forming plate 4 has been raised, the third telescopic member 22 and the first telescopic member 501 are extended and shortened respectively to drive the positioning rod 12, the lifting rod 14, the contact wheel 21, the first clamping plate 16 and the second clamping plate 17 to descend linearly relative to the forming plate 4. During the descent of the lifting rod 14, the first clamping plate 16 and the second clamping plate 17 are guided by the upper inclined portion of the guide groove 20 and gradually move toward the core 11. After the first clamping plate 16 and the second clamping plate 17 clamp the core 11, they will vertically descend along the inclined portion of the guide groove 20 until the first clamping plate 16 and the second clamping plate 17 are inserted into the interior of the accommodating groove 18. At this time, the distance the core 11 descends is L0. At this time, the distance between the forming plate 4 and the fixed mold 1 will increase to L1+a, and the distance between the forming plate 4 and the positioning rod 12 will be reduced to L2-a, thereby completing the height adjustment; It is worth noting that when the distance between the forming plate 4 and the cavity of the fixed mold 1 needs to be reduced, the first telescopic member 501 and the third telescopic member 22 still need to be extended and shortened first, and then the forming plate 4 is adjusted. After the forming plate 4 is adjusted, the first telescopic member 501 and the third telescopic member 22 directly insert the first clamping plate 16 and the second clamping plate 17 into the receiving groove 18; In the present invention, when the height of the forming plate 4 is adjusted, the first clamping plate 16 and the second clamping plate 17 keep clamping the core 11 to drive the core 11 to separate from the forming plate 4, thereby avoiding direct friction between the core 11 and the forming plate 4. After the height of the forming plate 4 is adjusted, the core 11 is inserted into the accommodating groove 18, thereby avoiding friction between the core 11 and the forming plate 4 when the distance between the bottom of the core 11 and the inner cavity of the fixed mold 1 remains unchanged.

[0032] As a further solution of the present invention, the second clamping plate 17 is wider than the first clamping plate 16 .

[0033] like Fig.15 and Fig.16 As shown: The second clamping plate 17 is larger than the first clamping plate 16 , so that the corresponding position of the receiving groove 18 and the second clamping plate 17 is wider, which can avoid scratching the core 11 during the rising process of the core 11 .

[0034] As a further solution of the present invention, the core 11 is connected to the positioning member 13 by bolts.

[0035] The core 11 connected by bolts can be easily disassembled and connected to the positioning member 13, thereby achieving the purpose of convenient replacement. Bolts are common knowledge in the prior art and are therefore not specifically shown.

[0036] As a further solution of the present invention, the driving assembly includes a hydraulic rod 23 fixedly connected between the fixed mold 1 and the top of the shell 3.

[0037] like Figure 2 As shown: The housing 3 is driven to rise and fall by the hydraulic rod 23, thereby completing mold opening and mold closing.
