Abstract
Description
Technical Field
[0001] This utility model relates to the field of die casting mold technology, specifically a differential pressure mold inclined surface insert assembly device. Background Technology
[0002] During the trial production and mass production of differential pressure molds, the complex cavity structure often leads to difficulties in machining certain areas, stress concentration after machining, and cracking during production. This results in mold repairs, increased labor and material costs, and reduced production efficiency. Therefore, in the design of differential pressure molds, selecting appropriate locations for insert combinations based on the product's shape characteristics can effectively reduce production costs, avoid the aforementioned problems leading to machine downtime and production stoppages, and improve production efficiency and service life. This process requires comprehensive consideration of factors such as the machining difficulty and service life of the mold and inserts, reducing stress concentration, and fulfilling the multiple functional requirements of the inserts. A reasonable and effective design of the insert combination device is necessary to achieve maximum cost savings and efficiency improvements. Utility Model Content
[0003] In view of this, the present invention aims to propose a differential pressure mold inclined surface insert assembly device, which can save costs and improve efficiency.
[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:
[0005] A differential pressure mold inclined surface insert assembly includes an insert assembly. The insert assembly has a water channel inside. The water channel includes a water inlet, a water outlet and at least one side hole. The side hole is blocked by a sealing element. The water inlet and the water outlet are connected to an external water pipe through a connector.
[0006] The ejector mechanism includes an ejector rod, an ejector rod sleeve, a pressure tube, and a pressure plate. The ejector rod sleeve is set in the ejector rod accessory through hole of the insert assembly. The pressure tube is placed on the ejector rod sleeve. The pressure plate fixes the insert assembly and the mold core together by a fastener. The ejector rod passes through the pressure plate, the pressure tube, and the ejector rod sleeve in sequence and finally extends to the forming surface.
[0007] An inclined mating structure is set at the molding part of the insert assembly and the corresponding part of the mold core. The two are tightly mated by the inclined surfaces to form a seal.
[0008] The exhaust structure is located on the side and inclined mating surface of the insert assembly to exhaust gas from the cavity.
[0009] In some embodiments, the water inlet and outlet of the water passage are connected to an external water pipe via a water passage compression fitting.
[0010] In some embodiments, the exhaust structure is an exhaust channel.
[0011] In some embodiments, the inclined mating surfaces of the insert assembly and the inclined mating surfaces of the mold core engage with each other at an acute angle.
[0012] Compared with the prior art, the differential pressure mold inclined surface insert assembly device of this utility model has the following advantages:
[0013] 1) Low usage and manufacturing costs. The inclined surface setting at an acute angle to the horizontal plane can effectively avoid the situation where the outer end face of the insert is sharp, reducing the vulnerability rate and design difficulty of the insert during processing, transportation and storage.
[0014] 2) Flexible design: By rationally designing the cavity and inclined surfaces, the size of the insert can be increased as needed, which facilitates increasing the design space requirements of the insert in water cooling, ejection, etc.
[0015] 3) Effectively meet the functional requirements of the shaped part in terms of exhaust, water cooling, and top output force.
[0016] 4) It provides effective reference for mold design with complex shapes and multiple functional requirements, broadening design thinking. In particular, it offers a reasonable design reference scheme for insert design with many functional requirements. Attached Figure Description

[0035] A differential pressure mold inclined surface insert assembly includes an insert assembly with an internal water channel including an inlet hole 14, an outlet hole 15, and at least one side hole 16. The side hole 16 is sealed by a sealing element. The inlet hole and outlet hole are connected to an external water pipe through a connector. A push rod mechanism includes a push rod 1, a push rod sleeve 7, a pressure pipe 8, and a pressure plate 5. The push rod sleeve 7 is disposed in the push rod accessory through hole 18 of the insert assembly. The pressure pipe is placed on the push rod sleeve. The pressure plate fixes the insert assembly and the mold core together by a fixing element. The push rod passes through the pressure plate, the pressure pipe, and the push rod sleeve in sequence, and finally extends to the forming surface. An inclined mating structure is disposed at the forming part of the insert assembly and the corresponding part of the mold core. The two are tightly mated by inclined surfaces to form a seal. An exhaust structure is disposed on the side of the insert assembly and the inclined mating surface for exhausting gas in the cavity.
[0036] The water inlet and outlet are connected to the external water pipe through the water pipe compression fitting 4, and the venting structure is the venting groove 12. The inclined mating surface of the insert assembly and the inclined mating surface of the mold core are mated at an acute angle to achieve sealing and reduce processing difficulty and damage rate.
[0037] In some embodiments, a differential pressure mold inclined surface insert assembly includes a push rod 1, a bolt 2, an inclined surface insert 3, a water channel ferrule connector 4, a pressure plate 5, a sealing rod 6, a push rod sleeve 7, and a pressure pipe 8. The insert 3 is provided with a bolt through hole 13, and the inclined surface insert 3 is provided with a water channel with a diameter of 8mm. The water channel has four water channel holes: an inlet hole 14, an outlet hole 15, and a side hole 16. The side hole 16 is sealed by welding after the sealing rod 6 is placed in it. The inlet hole 14, outlet hole 15, and water passage fitting 4 are tapped with NPT 1 / 4 threads. After connection, they are connected to the water pipe to achieve water flow. The insert ejector pin fitting through hole countersunk platform 19 holds the ejector pin sleeve 7. The pressure pipe 8 and pressure plate 5 are placed upwards in sequence. The pressure plate 5, insert 3, and mold core 9 are fixed together by bolts 2. The ejector pin 1 passes through the pressure plate 5, pressure pipe 8, and ejector pin sleeve 7 through the hole in sequence, and finally reaches the forming surface. The forming part of the insert 3 is provided with an insert inclined mating surface 10 at an acute angle to the horizontal plane. The corresponding part of the mold core 9 is also provided with a mold core inclined mating surface 11. The side of the insert 3 and the insert inclined mating surface 10 are provided with venting grooves 12 for gas to be discharged from the cavity. The insert 3 is placed vertically downwards until the insert hanging platform 17 is attached to the back of the mold core 9. At the same time, the insert inclined mating surface 10 and the mold core inclined mating surface 11 are tightly fitted to achieve a seal in this part. During the die-casting process, the gas inside the cavity is discharged through the venting groove 12 of the insert 3, and the cooling of this part is achieved through the water channel of the insert 3. During the mold opening process, the ejector pin 1 provides a pushing force to this part of the product through the ejector pin accessory through hole 18.
