Utility Model Content

[0005] In order to improve the efficiency of product production and reduce time and labor costs, the present application provides a pushing structure for a box mold.

[0006] The pusher structure of a box mold provided in this application adopts the following technical solution:

[0007] A pushing structure for a box mold comprises a base, a pair of limiting rods are respectively arranged on the left and right sides of the top surface of the base, the top ends of the limiting rods are connected to a fixed box, the fixed box is connected to a lifting device, the bottom of the lifting device is connected to a punch, the punch moves up and down along the vertical direction of the limiting rods, a die is fixedly arranged on the upper end surface of the base, a bottom plate is arranged in the inner cavity of the die, a lifting device is arranged at the bottom of the inner cavity of the die, a pushing device is arranged on one side in the width direction of the die, and a guide plate is arranged on the side of the die away from the pushing device.

[0008] By adopting the above technical solution and adding a pushing device, after the mold is made, the mold is pushed to the discharge port by the pushing device, eliminating the process of manual or machine taking materials from the mold device, improving production efficiency, and reducing time and labor costs.

[0009] Optionally, the pushing device includes a base, a first cylinder, a pushing plate and a fixed plate, the base is connected to one side of the die, the base is located on the top surface of the base, the length of the base is equal to the width of the die, a fixed plate is arranged on the top surface of the base, the fixed plate is connected to a pair of first cylinders, the other end of the first cylinder is connected to the pushing plate, the length of the pushing plate is the same as the length of the base, the height of the pushing plate is lower than the height of the fixed plate, there is a gap between the pushing plate and the base, and the pushing plate moves in a direction close to or away from the base.

[0010] By adopting the above technical solution, an electric-driven pushing device is added, the stability of the pushing operation is increased, the labor cost is reduced, and the production efficiency is further improved. The gap between the pushing plate and the base reduces the resistance to the movement of the pushing plate and saves energy.

[0011] Optionally, the lifting device includes a second cylinder and a push plate, the bottom of the second cylinder is connected to the base, the top of the second cylinder is connected to the push plate, the push plate is located in the middle sliding part of the bottom plate, and the push plate moves up and down in the inner cavity of the die.

Wear is likely to occur during the sliding process, resulting in the need to replace the sliding device. The guide sleeve is set to facilitate the replacement of only the guide sleeve that is prone to wear during the later maintenance process, thereby saving maintenance costs.

[0017] Optionally, a material injection port is provided at one end of the punch, and the material injection port extends to the bottom end of the punch, and the punch is located at the lower end of the lifting device.

[0018] By adopting the above technical solution, an injection port is added, which makes it easier for injection liquid to enter the punch, thereby facilitating the injection operation.

[0020] By adopting the above technical solution and adding the setting of the lifting device, the punch can slide downward along a straight line under the limiting action of the slide plate and the limiting rod, so that the punch can be accurately inserted into the inner cavity of the die, which facilitates the closing between the die and the punch, and thus facilitates the use of the device. There is no need for the operator to manually close the punch and the die, and it can also facilitate the precise docking between the punch and the die, further improving the product yield rate.

[0021] Optionally, the limit assembly includes a limit slot and a limit block, the limit slot is opened at the top of the inner cavity of the fixed box, one end of the two limit blocks are embedded in the inner cavity of the limit slot, one end of the two limit blocks can slide in the inner cavity of the limit slot, the other ends of the two limit blocks are respectively connected to the top of the two sliding blocks, the inner cavity of the limit slot is matched with the outer wall of the limit block and both are in a "T" shape.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The present application embodiment discloses a material pushing structure of a box mold. Figure 1 , Figure 2 and Figure 3 A pusher structure of a box mold includes a base 100, a pair of limit rods 400 are respectively arranged on the left and right sides of the top surface of the base 100, one end of the limit rods 400 are connected to the base 100, and the other end of the limit rods 400 are connected to the fixed box 700 on the top, the fixed box 700 is connected to the lifting device 600 by a pair of connecting rods 660, and the lifting device 600 is connected to a pair of slides 410, and the slides 410 drive the lifting device 600 to move up and down under the limiting action of the limit rods 400, thereby increasing the stability during the lifting process, the slides 410 are connected to the guide sleeves 420, and the guide sleeves 420 slide on the outer wall of the limit rods 400, and the bottom of the lifting device 600 is connected to the punch 500, and one end of the punch 500 is provided An injection port 510 is provided, and the injection port 510 is injected with material liquid for making the mold. The lifting device 600 drives the punch 500 to move up and down in the vertical direction of the limit rod 400. The base 100 is also connected to the die 200. The inner cavity of the die 200 is provided with a bottom plate 210. The bottom of the inner cavity of the die 200 is provided with a jacking device 220. The jacking device 220 drives the product to move upward to help the product to be quickly demolded. In addition, a pushing device 300 is provided on one side of the width direction of the die 200. The pushing device 300 pushes the product out of the mold device. A guide plate 230 is provided on the side of the die 200 away from the pushing device 300. The guide plate 230 helps the product to move smoothly and quickly. The whole process improves the efficiency of mold production.

[0034] Reference Figure 1 and Figure 3 The pushing device 300 includes a base 310, a first cylinder 330, a pushing plate 320 and a fixed plate 340. The base 310 is connected to one side of the die 200. The base 310 is located on the top surface of the base 100. The length of the base 310 is equal to the width of the die 200. A fixed plate 340 is arranged on the top surface of the base 310. The fixed plate 340 is equal to the base 310 in length. One end of the fixed plate 340 is connected to a pair of first cylinders 330. The other end of the first cylinder 330 is connected to the pushing plate 320. The length of the pushing plate 320 is The push plate 320 has the same length as the base 310 and is lower than the fixed plate 340. There is a gap between the push plate 320 and the base 310 to prevent friction between the push plate 320 and the die 200, thereby reducing resistance during the movement of the push plate 320. The push plate 320 moves in a direction approaching or away from the base 310, driving the product to move to the guide plate 230. There is no need to manually move the product out of the mold device, which speeds up the efficiency of removing the product from the mold device after demolding and improves the efficiency of the entire mold production.

[0035] Reference Figure 3The lifting device 220 includes a second cylinder 222 and a push plate 221. The bottom of the second cylinder 222 is connected to the base 100, and the top of the second cylinder 222 is connected to the push plate 221. The push plate 221 is located in the middle slidable part of the bottom plate 210. After the mold is formed, the second cylinder 222 lifts upward and pushes the push plate 221 to move upward. The push plate 221 pushes the product upward to break away from the adhesion between the product and the inner wall of the die 200, thereby achieving a quick demolding effect. After demolding, the second cylinder 222 falls back, and the push plate 221 immediately moves downward to prepare for the next lifting. Quick demolding improves the production efficiency of the product.

[0036] Reference Figure 1 and Figure 3 The lifting device 600 includes a motor 610, a screw rod 620, a slider 630, a slideway 640, a fixed seat 650, a connecting rod 660 and a limiting assembly 800. The motor 610 is started to drive the screw rod 620 to rotate, so that the threads on the left and right sides of the outer wall of the screw rod 620 generate relative thread rotation force, so that the two sliders 630 slide toward the middle of the screw rod 620 at the same time under the limiting action of the limiting groove 670 and the limiting block 680, so that the two connecting rods 660 push the fixed seat 650 and the punch 500 to drive the slide plate 410 to slide downward along a straight line under the limiting action of the limiting rod 400, so that the punch 500 is accurately inserted into the concave mold 200. The inner cavity of the device facilitates the precise closing between the die 200 and the punch 500, thereby facilitating the use of the device. There is no need for the operator to manually close the punch 500 and the die 200, and it is also convenient for the precise docking between the punch 500 and the die 200. The injection liquid is filled into the gap between the punch 500 and the die 200 through the injection port 510 for injection molding. After the injection liquid is cooled and formed, the two sliders 630 slide toward the two ends of the screw rod 620 at the same time under the limiting action of the limiting groove 670 and the limiting block 680, driving the connecting rod 660 to move. The connecting rod 660 drives the punch 500 to slide upward along a straight line under the limiting action of the limiting rod 400, and then the punch 500 returns to its original position.

[0037] Reference Figure 3 and Figure 4The limiting assembly 800 includes a limiting groove 670 and a limiting block 680. The limiting groove 670 is arranged at the top of the inner cavity of the fixed box 700. One ends of the two limiting blocks 680 are embedded in the inner cavity of the limiting groove 670. One ends of the two limiting blocks 680 can slide in the inner cavity of the limiting groove 670. The other ends of the two limiting blocks 680 are respectively connected to the tops of the two sliders 630. The two limiting blocks 680 can slide toward the middle of the screw rod 620 at the same time through the rotation of the screw rod 620, driving the punch 500 to descend. The two limiting blocks 680 can slide toward the two ends of the screw rod 620 at the same time through the reverse rotation of the screw rod 620, driving the punch 500 to return to its original position. The inner cavity of the limiting groove 670 and the outer wall of the limiting block 680 are matched and are both in a "T" shape, achieving a stable and fixed effect.

[0038] The implementation principle of the pushing structure of a box mold in an embodiment of the present application is as follows: when preparing to make the box mold, the lifting device drives the punch to descend and close the die, and the product is made after the injection port completes the injection. After the mold is processed and the product is formed, the product is lifted by the lifting device to quickly separate the product from the inner cavity of the die, thereby speeding up the demoulding efficiency. The product is pushed to the guide plate by the pushing device to complete the collection of the product after production, thereby improving the speed of removing the product from the mold device, shortening the entire product production time, and speeding up the product production efficiency.

[0039] The above is only an exemplary embodiment of the present disclosure and cannot be used to limit the scope of the present disclosure. That is, any equivalent changes and modifications made according to the teachings of the present disclosure are still within the scope of the present disclosure. After considering the disclosure of the specification and the truth of practice, it will be easy for those skilled in the art to think of other embodiments of the present disclosure.
