Description

Technical Field

[0001] This utility model belongs to the field of copper sleeve mold technology, specifically a copper sleeve mold that is easy to demold. Background Technology

[0002] Copper bushing molds are specialized tools used for copper bushing casting or forming. Through a pre-set cavity structure, they allow molten copper or copper material to form copper bushing workpieces that meet the size and shape requirements within the mold. They are key equipment for ensuring product precision and consistency during the copper bushing production process.

[0003] Traditional mold cavities often have straight or slightly angled inner walls. After the copper sleeve is formed, it comes into close contact with the inner wall of the cavity, which can easily generate strong clamping force due to cooling and shrinkage. At the same time, the mold lacks a dedicated demolding structure, and demolding often requires external force to knock, pry, or use complex tooling. This is not only cumbersome and time-consuming, but also easily leads to scratches and deformation on the surface of the copper sleeve, or even damage to the mold cavity, which seriously affects production efficiency and product quality. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a copper sleeve mold that is easy to demold, which effectively solves the current problem of inconvenient quick demolding of copper sleeves.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a copper sleeve mold that is easy to demold, including a base, a demolding mechanism on the top of the base, a support mechanism on the demolding mechanism, two molds symmetrically arranged above the base, the two molds fitting together, a mold column between the two molds, and a mold cavity formed between the mold column and the two molds;

[0006] The demolding mechanism includes a mounting plate located between two molds. Two guide rods are symmetrically fixedly connected between the bottom of the mounting plate and the base. Guide plates are fixedly connected to the outer sides of both molds. The two guide plates are movably sleeved on the outer sides of the two guide rods. A base plate is provided at the bottom of the mounting plate. The bottom end of the mold column passes through the mounting plate and is fixed to the top of the base plate. Two columns are symmetrically fixedly connected between the bottom of the mounting plate and the base. A lifting plate is movably sleeved between the two columns. Two connecting columns are symmetrically fixedly connected between the lifting plate and the base plate.

[0007] Preferably, a sleeve plate is fixedly sleeved on the outer side of each of the two guide rods. A drive motor is fixedly installed on the outer side of one of the sleeve plates. A bidirectional lead screw is fixedly connected to the drive motor. The end of the bidirectional lead screw away from the drive motor is rotatably connected to the other sleeve plate. Two nuts are symmetrically threaded on the outer side of the bidirectional lead screw. Two guide plates are fixed on the outer side of the two nuts respectively.

[0008] Preferably, a screw is rotatably connected to the top of the base, and a lifting plate is threaded onto the outside of the screw.

[0009] Preferably, a second bevel gear is fixedly connected to the top end of the screw, and a first bevel gear is fixedly installed on the outer side of the bidirectional lead screw, with the first bevel gear meshing with the second bevel gear.

[0010] Preferably, the support mechanism includes a support plate fixedly sleeved between two guide rods. The support plate is located outside the screw rod and does not contact it. The support plate is located between two connecting columns and above the lifting plate.

[0011] Preferably, an outer ring is fixedly sleeved on the outside of the screw, and multiple support columns are fixedly connected at equal angles to the bottom of the outer ring. Each support column has a ball bearing located at the top of the support plate at its bottom end.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The cooperation between the drive motor, the two-way lead screw, the lead screw nut, the guide plate and the guide rod facilitates the separation of the two molds. The cooperation between the bevel gear one, the bevel gear two, the screw, the lifting plate, the column, the connecting column and the chassis facilitates the removal of the mold column from the top of the mounting plate, thereby facilitating the exposure of the copper sleeve for quick demolding.

[0014] 2. The engagement between the outer ring and the support column, as well as the ball bearings and the support plate, can limit the screw and prevent it from shaking, thus ensuring the stability of the screw during rotation. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example 1, by Figure 1 The present invention relates to a copper sleeve mold that is easy to demold, including a base 1, a demolding mechanism 2 on the top of the base 1, a support mechanism 3 on the demolding mechanism 2, two molds 5 symmetrically arranged above the base 1, the two molds 5 fitting together, a mold column 4 between the two molds 5, and a mold cavity 6 formed between the mold column 4 and the two molds 5.

[0024] Specifically, by Figure 2The demolding mechanism 2 includes a mounting plate 201 located between two molds 5. Two guide rods 204 are symmetrically fixedly connected between the bottom of the mounting plate 201 and the base 1. Guide plates 2014 are fixedly connected to the outer sides of both molds 5. The two guide plates 2014 are movably sleeved on the outer sides of the two guide rods 204. A base plate 202 is provided at the bottom of the mounting plate 201. The bottom end of the mold column 4 passes through the mounting plate 201 and is fixed to the top of the base plate 202. Two columns 206 are symmetrically fixedly connected between the bottom of the mounting plate 201 and the base 1. A lifting plate 208 is movably sleeved between the two columns 206. Two connecting columns 203 are symmetrically fixedly connected between the lifting plate 208 and the base plate 202. The outer sides of the two guide rods 204 are fixedly... A sleeve plate 2013 is fixedly connected. A drive motor 205 is fixedly installed on the outer side of one of the sleeve plates 2013. A bidirectional lead screw 2012 is fixedly connected to the drive motor 205. The end of the bidirectional lead screw 2012 away from the drive motor 205 is rotatably connected to the other sleeve plate 2013. Two nuts 2011 are symmetrically threaded on the outer side of the bidirectional lead screw 2012. Two guide plates 2014 are fixed on the outer side of the two nuts 2011 respectively. A screw 209 is rotatably connected to the top of the base 1. A lifting plate 208 is threaded on the outer side of the screw 209. A bevel gear 2010 is fixedly connected to the top of the screw 209. A bevel gear 207 is fixedly installed on the outer side of the bidirectional lead screw 2012. The bevel gear 207 meshes with the bevel gear 2010.

[0025] In operation, the drive motor 205 is first started, which drives the bidirectional lead screw 2012 to rotate. Through the two lead screw nuts 2011, the two guide plates 2014 slide along the two guide rods 204 respectively. At the same time, the two molds 5 separate. When the bidirectional lead screw 2012 rotates, it drives the bevel gear 1 207 to rotate. Since the bevel gear 1 207 meshes with the bevel gear 2 2010, it drives the screw 209 to rotate and drives the lifting plate 208 to slide down along the two columns 206. Then, through the two connecting columns 203, it drives the chassis 202 to move down. At the same time, the mold column 4 descends until it is located at the bottom of the chassis 202, finally exposing the copper sleeve to achieve rapid demolding.

[0026] Specifically, by Figure 3-4 As shown, the support mechanism 3 includes a support plate 301 fixedly sleeved between two guide rods 204. The support plate 301 is located outside the screw 209 and does not contact the screw 209. The support plate 301 is located between two connecting columns 203 and above the lifting plate 208. An outer ring 302 is fixedly sleeved on the outside of the screw 209. Multiple support columns 304 are fixedly connected at equal angles at the bottom of the outer ring 302. Each support column 304 has a ball bearing 303 located at the top of the support plate 301 at its bottom end.

[0027] In use, when the screw 209 rotates, it drives the outer ring 302 to rotate. Through each support column 304, each ball 303 is driven to roll on the top of the support plate 301, thereby limiting the screw 209 to prevent it from shaking and ensuring the stability of the screw 209 when rotating.
