Description

Technical Field

[0001] The utility model relates to the technical field of glassware manufacturing equipment, in particular to a casting machine with a simple structure, convenient use and capable of greatly improving the production efficiency of glassware. Background Art

[0002] Glassware is a common daily necessity in modern life, which provides great convenience for people's lives. Common glassware includes fresh-keeping boxes, washing machine observation windows, juice cups, etc. During the production process of these glassware, usually, glass raw materials are first melted at high temperature to form a molten high-temperature glass liquid, and then the molten glass liquid is poured into each mold placed on a fixed platform. After the glass liquid in the mold naturally cools, workers manually use special clamping tools to take out the cooled and shaped glassware one by one and put them into subsequent processing equipment for the next process operation. This operation method not only has a high labor intensity, and workers need to perform repetitive operations on the products in all molds, but also is prone to product dropping due to operation fatigue during the operation process, resulting in damage and increasing the production cost. Therefore, at present, there is an urgent need for a glassware production equipment that can reduce the labor intensity of workers, improve production efficiency and reduce production costs. Summary of the Utility Model

[0003] The utility model provides a casting machine, which solves the problems of high labor intensity and high production cost in the production process of glassware in the prior art.

[0004] The technical solution of the utility model is realized as follows: The casting machine includes:

[0005] A sprocket wheel group, with two groups arranged side by side. Each sprocket wheel group is provided with a chain moving in a cycle, and the two chains move synchronously;

[0006] A mold bracket, with a plurality of them fixed to the chain in sequence and driven to move in a cycle by the two chains;

[0007] A mold, corresponding to the mold bracket one by one, and the mold is fixed to the mold bracket and moves synchronously with it.

[0008] As a preferred embodiment, a support frame corresponding to the mold bracket is fixed between the two chains. The support frame is composed of a flat plate part in the middle and bent parts at both ends;

[0009] The bent part is fixedly connected to the corresponding chain, and the mold bracket is screwed and fixed to the flat plate part through a threaded structure.

[0010] As a preferred embodiment, horizontal support plates which are symmetrically arranged and fixed are further provided above the chain. Vertical support plates which are bent upward are provided at one end of each of the two horizontal support plates close to each other. A narrow movement channel is formed between the two vertical support plates. The mold bracket fixed on the flat plate portion extends upward from the movement channel.

[0011] A balance plate located above the movement channel is further fixed on the mold bracket, and the vertical support plate is directly below the balance plate.

[0012] As a preferred embodiment, the balance plate has a square structure in the horizontal plane. There is an overlapping area in the vertical direction between adjacent balance plates, and all the balance plates are arranged in a staggered manner up and down in sequence.

[0013] As a preferred embodiment, grid-shaped cooling grooves are formed on the surface of the mold bracket for fixing the mold, and cooling water is provided in the cooling grooves.

[0014] As a preferred embodiment, the sprocket set is arranged on a movable base. A servo motor and a speed reducer for driving the sprocket set are provided on the base, and universal wheels are installed at the bottom of the base.

[0015] As a preferred embodiment, jacking cylinders and handles for controlling them are respectively installed at the four corner positions of the base. The height of the sprocket set can be adjusted by the actions of the jacking cylinders.

[0016] After adopting the above technical solutions, the beneficial effects of the present utility model are as follows: The casting machine of the present utility model drives two chains to move synchronously by using two sprocket sets, which can ensure the stability of the mold brackets fixed on the chains. The molds fixed on the mold brackets also have good stability, which can ensure that the molten glass inside the molds is cooled and solidified during the movement. During the movement of the molds, the molten glass inside them is naturally cooled. When the molds reach the end of the sprocket set, the finished products in the molds can automatically fall. Therefore, only a buffer pad or a conveyor belt needs to be provided below the end of the sprocket set to perform the operation continuously in a cycle. This structure does not require workers to perform repetitive operations on each mold, greatly reducing the labor intensity of the workers. After fixing the entire casting machine, only the molten glass needs to be poured into the circulating and moving molds at a fixed location. At the same time, for different mold types, the cooling time of the molten glass in the molds can be correspondingly changed by adjusting the rotation speed of the sprocket set to achieve the best cooling and solidification effect, and the production efficiency is also greatly improved.

Specific embodiments

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0026] Embodiment:

[0027] Such as Figure 1 、 Figure 2 And Figure 3Collectively shown are an embodiment of the casting machine of the present utility model, which are respectively the front view, top view and left view. The entire casting machine first includes a movable base 13, and a plurality of universal wheels 16 are installed at the bottom of the base 13 to facilitate the movement and adjustment of its position, angle, etc., so as to adapt to different production environments and requirements.

[0028] Vertical lifting cylinders 17 are also respectively installed at the four corner positions of the base 13. Each lifting cylinder 17 is provided with a corresponding handle 18. By rotating the handle 18, the telescopic movement of the lifting cylinder 17 can be controlled, so as to lift / lower the entire base 13 to adapt to different height requirements.

[0029] Two sets of sprocket groups 1 are installed on the base 13. These two sets of sprocket groups 1 are arranged side by side, and corresponding chains 2 are respectively wound thereon. The two chains 2 are also arranged side by side. As Figure 1 shown, the two sprockets on the left rotate synchronously, and they are key-connected to the same driving shaft. A servo motor 14 and a speed reducer 15 are also installed on the base 13, and the power output ends of the two are connected to the two sprockets on the left. Therefore, the two sprockets on the left are driving sprockets, and the two sprockets on the right are driven sprockets.

[0030] As Figure 4 、 Figure 5 and Figure 6 collectively shown, a number of die carriers 3 are sequentially arranged between the two chains 2. These die carriers 3 are driven by the two chains 2 to perform circular motion. A corresponding die 4 is fixed on each die carrier 3. The die 4 and the die carrier 3 can be fixed by a detachable connection method, so that different dies 4 can be replaced according to needs to produce different products. The molten glass liquid is directly poured into the die 4. During the process of the die carrier 3 driving the die 4 to move, natural cooling and shaping are realized. For example Figure 1 shown in, molten glass liquid is set at the left end of the chain 2. As the chain 2 rotates clockwise, the glass liquid is gradually poured into each die 4. The die 4 is gradually cooled and shaped during the process of moving from left to right. When it moves to the right end, the cooling and shaping are realized. At this time, the die 4 continues to move, and the cooled and shaped product falls from the die 4 under its own gravity. At this time, only a buffer pad or a conveyor belt needs to be set under the right end of the chain 2 to receive the product. And so on. Moreover, the movement speed of the chain 2 can be adjusted according to the cooling time of different products to ensure that the glass liquid has enough cooling and shaping time.

[0031] A number of support frames 5 are provided between two chains 2. The support frames 5 and the mold brackets 3 are in one-to-one correspondence. A mold bracket 3 is fixed on each support frame 5. The support frame 5 is composed of a flat plate portion 6 in the middle and bent portions 7 at both ends. Among them, the bent portions 7 are respectively fixed on the two side chains 2, and the mold bracket 3 is directly fixed on the middle flat plate portion 6. Here, it can be fixed by welding or can be detachably fixed by means of screw fitting. No matter which form, this symmetrical structure can ensure the stability of the mold bracket 3 during movement.

[0032] Above the two chains 2, horizontal support plates 8 are respectively provided. At the opposite ends of the two horizontal support plates 8, vertically bent support plates 9 are respectively provided. A narrow movement channel 10 is formed between the two vertically bent support plates 9, and the mold bracket 3 projects upward from the narrow movement channel 10. At the same time, a balance plate 11 located above the vertically bent support plate 9 is also fixed on the mold bracket 3. The balance plate 11 has a square structure in the horizontal plane, and there is an overlapping area between adjacent two balance plates 11 in the vertical direction. All the balance plates 11 are arranged in a staggered manner up and down in sequence. The function of setting the balance plate 11 is to ensure the movement stability of the entire casting machine. From Figure 1 and Figure 2 it can be seen that in order to ensure that the molten glass liquid has an appropriate cooling time, the left and right lengths of this casting machine are relatively long. Under the action of the self-gravity of the chains 2 and a number of mold brackets 3, the middle part thereof will inevitably show a sagging state. Coupled with the factor of pouring the molten glass liquid into the mold 4, the entire chain 2 will inevitably show a state of being lower in the middle and higher at both ends. In order to ensure its stability during movement, as Figure 6 shown, with the dual functions of the vertically bent support plates 9 and the balance plates 11, the two side vertically bent support plates 9 can play a role in lifting the balance plates 11, thereby ensuring the stability of the entire mold bracket 3. Moreover, there is an overlapping area between adjacent two balance plates 11 in the vertical direction, and the structural form in which all the balance plates 11 are arranged in a staggered manner up and down in sequence can also make the adjacent balance plates 11 press one on another, playing a role of mutual restriction and further improving the stability.

[0033] Finally, in order to accelerate the cooling time of the molten glass liquid in the mold 4, in this embodiment, a grid-shaped cooling groove 12 is opened on the surface of the mold bracket 3 for fixing the mold 4, and at the same time, cooling water is provided in the cooling groove 12. This part of the cooling water can be set as flowing cooling water according to needs, or other cooling media can be adopted.

[0034] Generally speaking, the casting machine of the present utility model has a simple structure, is easy to use, can greatly reduce the labor intensity of workers, improve production efficiency, and can be adjusted adaptively according to different working places, and has good practicability.

[0035] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
