Description

Technical Field

[0001] This utility model relates to the field of mold technology, and more specifically, to an iron-based composite vertical parting mold. Background Technology

[0002] Currently, the production of steel balls, steel forgings, hammers, and dumbbell balls mainly involves the following three methods:

[0003] Iron-based mold: A circular horizontal parting iron-based mold is adopted. The product cavity is set around the insulation area of ​​the mold. The cavity is made by combining two molds, and the middle insulation area is treated with a single-layer manual sandblasting process.

[0004] Sand-based models: produced through sand molding or shell-making processes. The core is to use metal mold plates to make sand mold cavities, and then combine them to form complete product cavities by using left-right or top-bottom parting methods.

[0005] Iron mold with sand coating: Based on a metal mold, a thin layer of sand is covered inside its cavity, and then the product cavity is formed by combining the upper and lower molds.

[0006] Among them, iron-based molds, as horizontal parting molds made by manual sandblasting, have prominent limitations in actual production: the production process relies on manual sandblasting, which is labor-intensive and the working environment is poor; at the same time, mechanized production cannot be implemented, and manual participation is required throughout the process, resulting in high labor costs and low production efficiency. The manual sandblasting process leads to low sand layer strength, which in turn results in poor product appearance quality; in addition, the small size of a single mold and the long casting time ultimately result in low overall output, making it difficult to meet the needs of large-scale production.

[0007] While sand-based molding and iron mold sand coating can achieve mechanized production, they still have many problems. The slow heat dissipation of the product under this process can easily lead to coarse metal structure, which directly reduces the performance of steel balls, steel forgings, and hammers. At the same time, the utilization rate of molten iron is low, the energy consumption is high, and the amount of sand used in the production process is large, which not only increases the consumption of raw materials but also brings higher environmental emission pressure. In addition, the production investment scale of sand-based molding is large, which makes it difficult for many small and medium-sized enterprises with limited financial strength to afford and therefore unable to adopt this production method.

[0038] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0039] Example 1

[0040] from Figure 1-5 As can be seen, the iron-based composite vertical parting mold of this embodiment includes an iron-based mold 1, which includes an iron-based mold one 101 and an iron-based mold two 102. The inner sides of the iron-based mold one 101 and the iron-based mold two 102 are provided with multiple sets of product cavities 103. The inner sides of the iron-based mold one 101 and the iron-based mold two 102 are also provided with a heat-insulating and shrink-compensating sprue cavity 104 and a horizontal sprue cavity 105. The heat-insulating and shrink-compensating sprue cavity 104 communicates with the product cavity 103 and the horizontal sprue cavity 105. The sprue assembly 2 is inserted into the heat-insulating and shrink-compensating sprue cavity 104 and the horizontal sprue cavity 105. The sprue assembly 2 is embedded in the iron-based mold 1 and together with the iron-based mold 1 forms a complete composite mold.

[0041] The gating assembly 2 includes a horizontal gating module 201 and a vertical gating module 202 that are interconnected. The horizontal gating module 201 is embedded in the horizontal gating cavity 105, and the vertical gating module 202 is embedded in the thermal insulation and shrinkage compensation vertical gating cavity 104. The surface of the horizontal gating module 201 is provided with a flow guide hole 2011, and the output end of the flow guide hole 2011 is connected to the vertical gating module 202. The surface of the vertical gating module 202 is provided with a flow divider hole 2021 at intervals.

[0042] The surface of the horizontal runner module 201 has a circular hole 2012. In contrast, one end of the vertical runner module 202 has a protrusion 2022. The vertical runner module 202 is fitted into the circular hole 2012 of the horizontal runner module 201 through the protrusion 2022.

[0043] The direct sprue module 202 and the horizontal sprue module 201 engage with each other to form a smooth channel for molten iron.

[0044] Multiple sets of product cavities 103 are provided and are arranged at intervals along the length and width directions of the iron-based mold 1. The output end of the diversion hole 2021 is connected to multiple sets of product cavities 103 respectively.

[0045] A vent hole 7 is provided at the top of the product cavity 103; the diameter of the vent hole 7 is less than 8mm, and the vent hole 7 extends upwards all the way to the top of the iron-based mold 1.

[0046] Positioning holes 3 are provided at the four corners of the iron-based mold 101 and the iron-based mold 202. The positioning holes 3 of the iron-based mold 101 and the iron-based mold 202 correspond to each other, thereby achieving the effect of mutual positioning; ensuring that the cavity remains intact and does not deviate when the iron-based mold 101 and the iron-based mold 202 are assembled by hydraulic means or other means.

[0047] Guide holes 4 are provided on both sides of the iron-based mold 101 and the iron-based mold 2 102. The guide holes 4 are for the guide rod to pass through in the future, so that the mold can move left and right in the guide rod and the two molds can move in the same direction.

[0048] The iron-based mold 101 and the iron-based mold 2102 are respectively provided with mounting holes 5 on both sides, and the iron-based mold 101 and the iron-based mold 2102 can be installed in the machine for use through the mounting holes 5.

[0049] The surface of the heat-insulating and shrinkage-compensating direct sprue cavity 104 is provided with ejector pin holes 6 at intervals. When the iron base mold 101 and iron base mold 202 are installed and used in the machine, the product in the mold cavity can be ejected from the machine.

[0050] This utility model relates to the field of metal casting and is a casting mold that can be used to produce steel balls and steel forgings. The base of the iron-based mold 1 is a metal iron base. The mold contains a product cavity 103, a heat-insulating and shrink-compensating sprue cavity 104 and a horizontal sprue cavity 105. A sprue module 202 and a horizontal sprue module 201 are respectively embedded in the heat-insulating and shrink-compensating sprue cavity 104 and the horizontal sprue cavity 105.

[0051] The direct sprue module 202 and the horizontal sprue module 201 can be made of resin sand or pressed with thermal insulation material, and after being made, they are embedded into the corresponding cavity.

[0052] After the sprue module 202 or the horizontal sprue module 201 is embedded into its respective cavity, it belongs to the same plane as the parting surface of the iron base mold 1. The left and right sides of the sprue module 202 each correspond to a product cavity 103. After the sprue module 202 and the cavity inside the horizontal sprue module 201 are connected, a complete molten iron cavity channel is formed.

[0053] The sprue module 202 can extend downward according to the size of the iron base mold 1. The left and right sides of the sprue module 202 each correspond to two product cavities 103 that extend synchronously. The sprue module 202 cooperates with the heat insulation and shrinkage compensation sprue cavity 104 to form multiple rows of complete product cavities 103. The product cavity 103 can be set with one or more cavities according to the shrinkage compensation conditions. Multiple cavities are connected in series, and the angle can be horizontal or have an included angle.

[0054] The base of the iron-based mold 1 of this utility model is a metallic iron base. The iron base dissipates heat quickly, has a dense structure, and has excellent performance. The horizontal sprue module 201 and the heat-insulating and feeding sprue module 202 allow the product quantity to be extended downwards according to the mold size, which can increase output, shorten casting time, and save costs. The iron base dissipates heat quickly, while the heat-insulating and feeding module dissipates heat slowly, allowing the product to achieve complete feeding. The size of the feeding riser is reduced, the product energy consumption is reduced, the product output is increased, and the cost is reduced. The increased molten iron height and the increased static pressure of the molten iron improve the product quality.

[0055] This invention enables mechanized assembly line production. It employs a fixed mold (e.g., a fixed iron-based mold 101) and another mold (e.g., an iron-based mold 2 102) that moves within a guide rod using hydraulic pressure or other means. The mold cavities are aligned, and the horizontal runner module 201 and the vertical runner module 202 are embedded. Hydraulic pushing ensures that the molds are assembled, and positioning pins ensure that the cavities are not misaligned, forming a complete product cavity. The process is automatic pouring and automatic separation, simple to operate, reduces manual labor, improves the environment, and lowers costs.

[0056] Iron-based mold 101 and iron-based mold 2102 are joined together to form a complete product cavity and molten iron channel cavity, and the molten iron channel also serves as a shrinkage compensation function.

[0057] When the product cavity size is small, multiple insulated and shrink-compensating sprue cavities can be vertically implemented within a single iron-based mold 1. The molten iron channel cavity within each insulated and shrink-compensating sprue module is connected to the molten iron channel cavity within the horizontal sprue module, and the connection can be achieved using a mother-daughter groove. When the product size is large, a single insulated and shrink-compensating sprue module can be set horizontally, and the vertical insulated and shrink-compensating sprue module can be lengthened to implement multiple product cavities. In this way, the number of mold product cavities increases, production output increases, and costs decrease.

[0058] The dimensions of the horizontal runner module 201 and the vertical runner module 202 can be adjusted according to the product size. The module has a cavity with a molten iron channel. The volume of the molten iron channel cavity generally does not exceed 30% of the total cavity of the product. The shape can be cylindrical and / or rectangular.

[0059] The dimensions of the iron-based mold 1 can be reasonably arranged according to the size and number of product cavities 103. Considering both economy and practicality, it is more reasonable to arrange the dimensions within 650*650*100MM.

[0060] Example 2

[0061] from Figure 6-8 As can be seen, the iron-based composite vertical parting mold of this embodiment includes an iron-based mold 1, which includes an iron-based mold 101 and an iron-based mold 2 102. Both the iron-based mold 101 and the iron-based mold 2 102 have multiple sets of product cavities 103 on their inner sides. The product cavities 103 of this embodiment have six rows, each with nine holes, which can be used to produce steel balls with a diameter of 40mm.

[0062] Example 3

[0063] from Figure 9-10 As can be seen, the iron-based composite vertical parting mold of this embodiment includes an iron-based mold 1, which includes an iron-based mold 101 and an iron-based mold 2 102. Both the iron-based mold 101 and the iron-based mold 2 102 have multiple sets of product cavities 103 on their inner sides. The product cavities 103 of this embodiment have two rows, each with four holes, which can be used to produce steel balls with a diameter of 80mm.

[0064] Examples 1-3 show several sizes used in steel ball production; the iron-based mold 1 of this application is not limited to the above sizes.

[0065] Example 4

[0066] from Figure 11-12 As can be seen, the iron-based composite vertical parting mold of this embodiment, which is a hammer mold, differs from the steel ball mold of embodiments 1-3 in that a sand core hole 8 is provided in the product cavity 103. The sand core hole 8 penetrates the product cavity 103 and extends to the iron-based mold 1. For some castings that require sand core holes, the sand core can be placed on the outside of the iron-based mold 1 through the sand core hole 8. In this embodiment, the product cavity 103 has two rows of six holes each, which can be used to produce hammers.

[0067] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
