A mold that facilitates demolding

Abstract

This utility model relates to the field of metal casting mold technology and discloses a mold that facilitates demolding. It includes a receiving groove with a vertical plate fixed to its side wall. After casting, the telescopic rod extends, causing the upper mold to move upwards and detach from the lower mold. Then, the upper top block can be pulled outwards from the bottom of the lower mold. At this point, power is stopped to the electromagnet, releasing the magnetic lock on the lower mold. The lower mold then rotates downwards under the support of the rotating shaft and support frame. The protective strip then collides with the collision strip. The opening of the lower mold faces downwards, allowing the formed material inside to be easily discharged downwards for demolding. Simultaneously, the material is subjected to centrifugal force during the rotation of the lower mold, further facilitating demolding. This solves the problem of common casting molds where the formed material is located inside the lower mold cavity, making demolding difficult and allowing for long-term use of the mold.

Description

Technical Field

[0001] This utility model relates to the field of metal casting mold technology, specifically a mold that is easy to demold. Background Technology

[0002] Metal casting molds are tools used in the casting process to help form metal parts. They are typically made of steel or cast iron to withstand high temperatures and pressures. They are not only wear-resistant but also have good thermal conductivity, allowing molten metal to cool and solidify rapidly, ensuring the dimensional accuracy and surface finish of the castings. Casting molds are used to pour molten copper solution into rectangular block structures.

[0003] Existing casting molds typically consist of upper and lower molds that can be joined together. When the upper mold is joined to the top of the lower mold, a molding cavity is formed inside the lower mold. Molten metal is then injected into the molding cavity through the pouring port to perform the molding operation. However, after molding, the material is inside the lower mold, and manual demolding with tools is often required, making the demolding operation cumbersome and inconvenient. Furthermore, the material is not easy to remove because it is attached to the inside of the molding cavity. Therefore, we propose a mold that facilitates demolding. Utility Model Content

[0004] The purpose of this invention is to provide a mold that facilitates demolding, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mold for easy demolding, comprising a receiving groove, a vertical plate fixedly connected to the side wall of the receiving groove, a plurality of telescopic rods provided at the top of the vertical plate, a top plate provided at the power output end of the telescopic rods, an upper mold fixedly connected to the side wall of the top plate, a lower mold provided on the side wall of the top plate, a rotating shaft fixedly connected to the side wall of the lower mold, a support frame fixedly connected to the vertical plate on the side wall of the rotating shaft, a protective strip provided on one side of the lower mold, an iron strip provided on the other side, a fixing strip fixedly connected to the right side wall of the vertical plate, and a plurality of electromagnets embedded at the top of the fixing strip.

[0006] Preferably, the receiving groove is provided with an inclined panel inside, and the lower mold is fitted to the top of the receiving groove.

[0007] Preferably, the upper mold is provided with a pouring port at the top, and the upper mold is fitted to the top of the lower mold.

[0008] Preferably, a snap-fit ​​component is fixedly connected to the top of the receiving trough, and an upper top block is slidably fitted inside the snap-fit ​​component.

[0009] Preferably, a limiting rod passes through the side wall of the upper block, and the limiting rod is fixed to the inner wall of the snap-fit ​​component.

[0010] Preferably, an air pump that works with the telescopic rod is fixedly connected to the left side wall of the vertical plate, and a collision strip is fixedly connected to the right side wall of the vertical plate.

[0011] Preferably, the sidewall of the collision strip is provided with a rubber strip, and the rubber strip has an arc-shaped structure.

[0012] Preferably, a connecting piece is fixedly connected to the bottom of the snap-fit ​​component, and the connecting piece is fixedly connected to the side wall of the receiving groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. After casting, the telescopic rod extends, causing the upper mold to move upward and detach from the lower mold. Then, the upper top block can be pulled outward from the bottom of the lower mold. At this time, the power supply to the electromagnet is stopped, releasing the magnetic lock on the lower mold. This allows the lower mold to rotate downward under the support of the rotating shaft and the support frame. Then, the protective strip will collide with the collision strip. At this time, the opening of the lower mold faces downward, allowing the material inside to be easily discharged downward for demolding. At the same time, when the lower mold rotates, the material will be subjected to centrifugal force, which is more conducive to demolding. This solves the problem of the common casting mold where the material is located inside the lower mold cavity, making demolding inconvenient. It is convenient for long-term use of the mold. After the material is ejected, it will fall into the receiving groove and be discharged to the left to collect the material.

[0015] 2. When demolding is completed, the lower mold can be rotated upwards. At this time, the electromagnet is energized, causing it to magnetically attract the iron bar at the bottom of the lower mold, thus achieving magnetic locking of the lower mold. Simultaneously, the upper top block of the snap-fit ​​component can be slid backwards to engage with the bottom of the lower mold. At this time, the telescopic rod can be retracted, allowing the upper mold to be assembled with the lower mold for casting and molding operations. Thus, the sliding upper top block can be used to support the bottom of the lower mold, improving the stability of the lower mold after magnetic locking, which is beneficial for the long-term stable use of the mold.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example

[0023] Please see Figures 1-4The illustration shows a mold for easy demolding, including a receiving groove 100. A vertical plate 110 is bolted to the side wall of the receiving groove 100. Multiple telescopic rods 111 are mounted on the top of the vertical plate 110. The telescopic rods 111 use commercially available telescopic cylinders. The main structure of the telescopic cylinder includes an outer cylinder, piston, piston rod, sealing system, air inlet, return spring, and exhaust port. It is connected to a commercially available air pump 160 as an air source. Its working principle is that the air pump 160 provides compressed air, which enters the cylinder and pushes the piston forward, achieving telescopic movement. When the air pump 160 stops supplying air... When the cylinder is in operation, the gas inside is released through the exhaust port, and the piston automatically returns under the action of the spring. The air pump 160 is equipped with an external programmable PLC controller as a control switch, and the programmable PLC controller is connected to an external circuit for power supply via a power cord. The power output end of the telescopic rod 111 is equipped with a top plate 112. An upper mold 113 is fixed to the side wall of the top plate 112, and a lower mold 120 is provided on the side wall of the top plate 112. A rotating shaft 123 is tightly welded to the side wall of the lower mold 120. The rotating shaft 123 is located on the left side of the bottom of the lower mold 120, so that the rotating shaft 123... The lower mold 120 on the right side is heavier than the lower mold 120 on the left side of the rotating shaft 123. Therefore, when the lower mold 120 is no longer attracted by the electromagnet 131 or blocked by the upper push block 152, it will deflect to the right under the influence of gravity. A support frame 122 fixed to the vertical plate 110 is provided on the side wall of the rotating shaft 123. A protective strip 121 made of rubber is provided on one side of the lower mold 120, and an iron strip 124 that engages with the top of the electromagnet 131 is provided on the other side. When the lower mold 120 rotates to a horizontal position with the opening facing upwards, the iron strip 124 on the left side of the lower mold 120... 24 fits perfectly on the top of the electromagnet 131 of the fixing strip 130. The fixing strip 130 is fixed to the right side wall of the vertical plate 110. Multiple electromagnets 131 are embedded in the top of the fixing strip 130. The electromagnets 131 use common models on the market. The electromagnet 131 is mainly composed of a conductor coil, an iron core and a power button switch. When current passes through the conductor coil, a magnetic field is generated around it. If an iron core is placed inside the conductor coil, the iron core will be strengthened by the magnetic field, thus forming a strong magnet. When the current stops flowing, the magnetism of the electromagnet will also disappear quickly. The power button switch is powered by an external power supply connected to a power cord.

[0024] Specifically, the receiving groove 100 is provided with an inclined panel 101, which is made of a smooth silicone plate, and the lower mold 120 is fitted to the top of the receiving groove 100.

[0025] Furthermore, the upper mold 113 is provided with a pouring port 114 at the top. The upper mold 113 is fitted to the top of the lower mold 120. When the upper mold 113 is assembled to the top of the lower mold 120, a molding cavity is formed inside the lower mold 120. Molten metal is then injected into the molding cavity through the pouring port 114 to perform the molding operation.

[0026] Furthermore, the top of the receiving trough 100 is fixed with a snap-fit ​​component 150 by bolts, and the snap-fit ​​component 150 has an upper top block 152 that slides inside it. The upper top block 152 is made of common stainless steel.

[0027] Furthermore, the upper block 152 has a limit rod 153 extending through its side wall. The upper block 152 slides under the limit of the limit rod 153 and the locking member 150 outside the locking member 150. The limit rod 153 is fixed to the inner wall of the locking member 150 by bolts.

[0028] Furthermore, an air pump 160 connected to the telescopic rod 111 is bolted to the left side wall of the vertical plate 110. The air pump 160 is equipped with a stainless steel protective shell. A collision strip 140 is bolted to the right side wall of the vertical plate 110.

[0029] It is worth noting that the side wall of the collision strip 140 is provided with a rubber strip 141, which has an arc-shaped structure.

[0030] It is worth noting that the bottom of the snap-fit ​​150 is fixed with a connecting piece 151 by bolts, and the connecting piece 151 is fixed to the side wall of the receiving groove 100 by bolts.

[0031] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0032] Working principle: After casting, the telescopic rod 111 extends, causing the upper mold 113 to move upward and disengage from the lower mold 120. Then, the upper top block 152 can be pulled outward from the bottom of the lower mold 120. At this time, power supply to the electromagnet 131 is stopped, releasing the magnetic lock on the lower mold 120. Thus, the lower mold 120 rotates downward under the support of the rotating shaft 123 and the support frame 122. Then, the protective strip 121 will collide with the collision strip 140. At this time, the opening of the lower mold 120 faces downward, allowing the internally formed material to be easily discharged downward for demolding. At the same time, when the lower mold 120 rotates, the formed material will be subjected to centrifugal force, which further facilitates demolding. This solves the common problem of the formed material being located in the lower mold of casting molds. The 120 cavity is not inconvenient for demolding, which facilitates long-term use of the mold. When demolding is completed, the lower mold 120 can be rotated upwards. At this time, the electromagnet 131 is energized, causing it to magnetically attract the iron bar 124 at the bottom of the lower mold 120, thus achieving magnetic locking of the lower mold 120. At the same time, the upper push block 152 of the snap-fit ​​part 150 can be slid backwards to fit into the bottom of the lower mold 120. At this time, the telescopic rod 111 can be retracted, allowing the upper mold 113 to be assembled with the lower mold 120 for casting. Thus, the sliding upper push block 152 can be used to support the bottom of the lower mold 120, improving the stability of the lower mold 120 after magnetic locking, which is conducive to the long-term stable use of the mold.
