Description

Technical Field

[0001] The utility model relates to the technical field of mold cooling, in particular to a blow molding mold comprising a special cooling system. Background Art

[0002] Blow molding, also known as hollow blow molding, is a rapidly developing plastic processing method. The tubular plastic preform obtained by extrusion or injection molding of thermoplastic resin is placed in a split mold while hot (or heated to a softened state). After the mold is closed, compressed air is immediately introduced into the preform to inflate the plastic preform and make it adhere tightly to the inner wall of the mold. After cooling and demolding, various hollow products are obtained.

[0003] When an existing blow molding mold is in use, usually during the process of the mold base being blown up in the mold, a cooling medium flows through the mold hole to the mold cavity, absorbs heat from the container through the mold wall, and gradually cools and shapes the container. However, in actual operation, the cooling medium enters the mold cavity too early, resulting in a decrease in the mold cavity temperature during the blow molding of the mold base, making the mold base difficult to blow up, or causing the wall thickness of the plastic product to be uneven, thereby affecting the quality of the plastic product. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a blow molding mold including a dedicated cooling system to solve the above problems.

[0005] The utility model discloses a blow molding mold including a special cooling system, which includes a blow molding mold, wherein the blow molding mold includes a mold body A and a mold body B arranged on one side of the mold body A, control components are symmetrically installed at the tops of the mold body A and the mold body B, a mold cavity is opened inside the mold body A and one side of the mold body B, a mold cavity is installed at the middle end of the mold cavity, an inner transverse bending plate A and an inner transverse bending plate B are installed in sequence from top to bottom inside the mold cavity, a drainage pipe is symmetrically installed at the bottom end of the mold body A and the mold body B, a water inlet pipe is symmetrically installed on one side of the mold body A and the mold body B, the water inlet pipe is communicated with the inside of the mold cavity, a filling block is installed inside the mold body A and the mold body B, one side of the filling block is connected to the upper end of the mold cavity, a waterproof board is installed on one side of the mold cavity, and the waterproof board is installed on one side of the inner transverse bending plate A and the inner transverse bending plate B.

[0006] By adopting the above technical scheme, the mold cavity inside the mold body A and the mold body B is used for blow molding. During blow molding, the blow molding tube first blows up the plastic product, and then stops blowing. After the mold body A contacts the mold body B, the blow molding tube continues to blow while moving downward. The heat of the plastic product is transferred by the mold cavity. At this time, the control component at one end of the water inlet pipe moves, and the cooling water is discharged into the interior of the mold cavity through the water inlet pipe. During the blow molding process, the cooling water flows along the inner transverse bend plate A and the inner transverse bend plate B to cool the heat absorbed by the mold cavity. At the same time, the inner transverse bend plate A and the inner transverse bend plate B set will reduce the flow rate of the cooling water.

[0007] Preferably, internally threaded pipes are symmetrically installed on the outer sides of the mold body A and the mold body B, and the internal threads of the internally threaded pipes are connected with temperature sensors.

[0008] By adopting the above technical solution, the temperature of the cooling water inside the mold cavity can be effectively monitored by the temperature sensor to avoid insufficient cooling of the mold.

[0009] Furthermore, the control component includes a pressing plate and a moving rod installed at the bottom end of the pressing plate, a baffle is installed at the bottom end of the moving rod, and the inner walls of the mold body A and the mold body B are provided with moving grooves, and the baffle is slidably installed inside the moving groove.

[0010] Preferably, limit bars are installed on both sides of the baffle, limit sliding grooves are provided on both sides of the movable groove, and the limit bars are installed inside the limit sliding grooves in a limit sliding manner.

[0011] Preferably, a control hole is opened at the top of the mold body A and the mold body B, the moving rod is movably installed inside the control hole, a rubber ring is installed on the outer surface of the moving rod, a compression spring is installed on the bottom end of the pressing plate, and the compression spring is sleeved on the outer surface of the moving rod.

[0012] By adopting the above technical solution, during the downward movement of the blow molding tube, the control hole and the limiting slide groove are used to limit the downward movement range of the moving rod and the baffle. After the baffle at one end of the water inlet pipe moves downward, the cooling water can be discharged into the inner cavity of the mold through the water inlet pipe, effectively controlling the time for the cooling water to enter the inner cavity of the mold. The rubber ring blocks the gap between the control hole and the inner transverse bending plate A to prevent the cooling water from flowing out.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The utility model provides a blow molding mold including a special cooling system, which adopts water cooling to achieve cooling of the mold. The time for cooling water to enter the mold cavity is controlled by a control component. The inner transverse bending plate A and the inner transverse bending plate B are arranged to increase the flow time of cooling water in the mold cavity, and the cooling range of the mold cavity is controlled to avoid affecting the fluidity of the plastic raw liquid before the blow molding is completed.
