[0002] In the plastics manufacturing industry, mold supports are often used to support the molding die. During the molding process, rapid demolding is necessary to ensure production efficiency and product quality. However, traditional plastics molding machines cannot automatically reset the mold support after demolding, leading to cumbersome and time-consuming manual reset in subsequent production, resulting in low production efficiency. Furthermore, manual reset is inaccurate, easily causing mold wear after repeated production runs. This not only affects the mold's lifespan and increases production costs but also affects the molding precision of the plastic products, ultimately reducing product quality. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a mold support for a plastic product molding machine, thereby solving the technical problem that traditional plastic product molding machine mold supports cannot automatically reset after demolding.

[0004] The purpose and effect of this utility model for a mold support for a plastic product molding machine are achieved by the following specific technical means:

[0005] A mold support for a plastic product molding machine includes a base with two sets of support plates located at both ends. Multiple guide shafts are positioned between the two sets of support plates, with each end of a guide shaft respectively secured within one of the support plates. Two mounting plates and two clamping plates are sleeved on each guide shaft, mirror images of the mounting and clamping plates. A die and a punch are respectively secured within each mounting plate. A fixing assembly is mounted on the mounting plate. A mold-closing cylinder is mounted on one side of each support plate, with its shaft end connected to one end of the clamping plate. A demolding assembly is located at one end of the die. A discharge groove is provided on the base, and an installation groove is provided on one side, where a control module is installed.

[0006] According to a preferred embodiment, the demolding assembly includes a demolding template, which is located at one end of a set of clamping plates at one end of the die cavity. The demolding template is provided with multiple sets of ejector rods, and one end of the die cavity is provided with multiple sets of ejector holes. One end of the clamping plates is provided with multiple sets of through holes, and the ejector rods pass through the through holes and the ejector holes.

[0007] According to a preferred embodiment, the demolding assembly further includes a top plate, which is sleeved on the guide shaft and located at one end of the demolding template. The top plate has a clearance hole, and the mold closing cylinder passes through the clearance hole.

[0008] According to a preferred embodiment, a return spring is sleeved on the ejector rod, and the return spring is located between a set of clamping plates at one end of the ejector plate and the die cavity; a buffer block is provided at one end of the top plate, and the buffer block is located at one end of the ejector plate.

[0009] According to a preferred embodiment, the fixing component includes a mounting box and a fixing block. The mounting box is mounted on the mounting plate, and the fixing block is engaged in the mounting box. Fixing grooves are provided on both the concave mold and the convex mold. Corresponding through grooves are provided on the mounting plate, and the bottom of the fixing block passes through the through groove and is engaged in the fixing groove.

[0010] According to a preferred embodiment, the fixing component further includes a fixing spring, which is snapped into the mounting box. The mounting box is provided with a cover plate, and the fixing spring is located between the cover plate and the fixing block.

[0011] According to a preferred embodiment, a groove is provided on one side of the mounting box, and a pull ring is provided on one side of the fixing block, with the pull ring passing through the groove; the bottom of the fixing block is triangular, and the hypotenuses of the two sets of fixing blocks face the concave mold and the convex mold respectively.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model relates to a mold support for a plastic product molding machine, which is based on a base. Support plates at both ends of the base provide lateral support for the entire assembly, and a guide shaft between the support plates guides the movement of the mounting plate and clamping plate. The mounting plate and clamping plate are mirror images of each other, respectively holding the concave mold and the convex mold. A fixing component on the mounting plate stabilizes the mold. A mold-closing cylinder on one side of the support plate controls the opening and closing of the concave mold and the convex mold. A demolding component at one end of the concave mold is used for demolding. The base is equipped with a control module to regulate each component.

[0014] 2. During use, the control module activates the mold-closing cylinder to close the mold and form the plastic product.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0022] Example:

[0023] like Figures 1 to 4 As shown, this utility model provides a mold support for a plastic product molding machine, including a base 11. Two sets of support plates 12 are provided on the base 11, located at opposite ends of the base 11, providing lateral support for the entire mold support. Multiple sets of guide shafts are arranged between the two sets of support plates 12, with both ends of the guide shafts respectively engaged within the two sets of support plates 12, providing stable guidance for the movement of mounting plates 13 and clamping plates 14. Two sets of mounting plates 13 and two sets of clamping plates 14 are sleeved on the guide shafts. The clamping plates 14 are located at one end of the mounting plates 13 and have slots on them. One end of the mounting plates 13 is engaged within these slots, and the two sets of mounting plates 13 and the two sets of clamping plates 14 are arranged in a mirror image, making the mold support more symmetrical and stable in structure. A concave mold 15 and a convex mold 16 are respectively engaged within the two sets of mounting plates 13, with one end of the concave mold 15 and the convex mold 16 connected to the two sets of clamping plates 14. These are key components for plastic product molding.

[0024] A fixing assembly is mounted on the mounting plate 13 to securely fix the die 15 and punch 16 to the mounting plate 13. A mold-closing cylinder is mounted on one side of the support plate 12. The shaft end of the mold-closing cylinder is connected to one end of the clamping plate 14. By extending and retracting the mold-closing cylinder, the clamping plate 14 can be pushed to move along the guide shaft, thereby realizing the mold-closing and mold-opening actions of the die 15 and punch 16. A demolding assembly is provided at one end of the die 15 for smooth demolding of the plastic product after molding. A discharge groove is provided on the base 11 for easy unloading of the molded plastic product. A mounting groove is provided on one side of the base 11, and a control module 17 is installed in the mounting groove. The control module 17 can be a Raspberry Pi 4B control module to regulate the operation of each component.

[0025] like Figures 2 to 3 As shown, the demolding assembly includes a demolding plate 18, which is located at one end of a set of clamping plates 14 at one end of the cavity mold 15. The demolding plate 18 is provided with multiple sets of ejector rods, and one end of the cavity mold 15 has multiple sets of ejector holes. One end of the clamping plates 14 has multiple sets of through holes corresponding to the multiple sets of ejector holes. The ejector rods are sequentially inserted into the through holes and ejector holes. After the plastic product is molded, the ejector rods can pass through the holes in the clamping plates 14 and the cavity mold 15, ejecting the plastic product from the cavity mold 15, thus completing the demolding operation.

[0026] The demolding assembly also includes a top plate 19, which is sleeved on the guide shaft and located at one end of the demolding template 18. The top plate 19 has a clearance hole, and the mold closing cylinder passes through the clearance hole. This not only does not affect the normal operation of the mold closing cylinder, but also provides support and positioning for the demolding template 18, making the demolding process more stable.

[0027] A return spring is fitted onto the ejector rod, located between a set of clamping plates 14 at one end of the ejector plate 18 and the die 15. After the plastic product is ejected, the return spring returns the ejector rod and the ejector plate 18 to their initial positions for the next demolding operation. A pad is provided at one end of the top plate 19, located at one end of the ejector plate 18. The pad prevents contact between the ejector plate 18 and the top plate 19 during demolding, reducing wear caused by direct contact and extending the service life of both the ejector plate 18 and the top plate 19.

[0028] like Figure 2 , Figure 4 As shown, the fixing assembly includes a mounting box 21 and a fixing block 22. The mounting box 21 is mounted on the mounting plate 13, providing installation space for the fixing block 22. The fixing block 22 is engaged within the mounting box 21 and can slide up and down within the mounting box 21. Both the die 15 and the punch 16 have fixing grooves, and the mounting plate 13 has corresponding through grooves. The bottom of the fixing block 22 passes through the through groove and is engaged within the fixing groove, thereby stably mounting the die 15 and the punch 16 on the mounting plate 13.

[0029] The fixing assembly also includes a fixing spring 23, which is fitted inside the mounting box 21. The mounting box 21 is provided with a cover plate, and the fixing spring 23 is located between the cover plate and the fixing block 22. The top of the fixing block 22 has a square groove, and the bottom of the fixing spring 23 is fitted into the square groove. The fixing spring 23 provides elastic force to the fixing block 22, allowing it to be tightly fitted into the fixing grooves of the die 15 and the punch 16, thereby enhancing the stability of the fixing.

[0030] A groove is provided on one side of the mounting box 21, and a pull ring is provided on one side of the fixing block 22, which passes through the groove. By pulling the pull ring, the movement of the fixing block 22 within the mounting box 21 can be easily controlled, facilitating the installation and removal of the cavity mold 15 and the punch mold 16. The bottom of the fixing block 22 is triangular, with the hypotenuses of the two sets of fixing blocks 22 facing the cavity mold 15 and the punch mold 16 respectively. This shape helps the fixing block 22 to more easily snap into the fixing groove during installation.

[0031] The specific usage and function of this embodiment are as follows:

[0032] When using this mold support, the control module 17 activates the mold-closing cylinder. The shaft end of the mold-closing cylinder pushes the clamping plate 14, causing the die 15 and punch 16 on the mounting plate 13 to move towards each other along the guide shaft to complete the mold closing and form the plastic product. After forming, the control module 17 controls the mold-closing cylinder to retract, driving the die 15 and the ejector plate 18 to move. When it moves to one end of the top plate 19, the ejector plate 18 contacts the pad at one end of the top plate 19. The mold-closing cylinder continues to retract, and the ejector rod at one end of the ejector plate 18 passes through the ejector hole of the die 15 to eject the plastic product. The plastic product falls through the unloading groove. During the next mold closing, the return spring separates the ejector plate 18 from the clamping plate 14 at one end of the die 15, completing the reset.

[0033] To replace the concave mold 15 or the convex mold 16, pull the pull ring on the fixing block 22 to disengage the fixing block 22 from the fixing groove, allowing the mold to be removed for replacement. After replacement, under the action of the fixing spring 23, the fixing block 22 engages with the fixing groove of the new mold. Throughout the process, all components work together to achieve the molding, demolding, and mold replacement of plastic products, meeting the production needs of plastic products.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
