Technical Field
[0001] The utility model relates to the technical field of hot core box molds, in particular to a hot core box roller device. Background Art
[0002] In the production process of cylinder blocks and cylinder heads, when using hot core box cylinder core making, the rollers used in the hot core box mold have a very short service life due to the high heating temperature during core making, making replacement difficult and the cost of the finished rollers high. Utility Model Content
[0003] In order to solve the above problems, a hot core box roller device is designed, which not only ensures the service life but also saves costs.
[0004] The embodiment of the utility model is implemented as follows: a hot core box roller device comprises: a hot core box mold and a roller mechanism, wherein the roller mechanism is installed at the lower end of the hot core box mold, and the hot core box mold can be moved by the roller mechanism; a slideway, which is arranged in cooperation with the roller mechanism, and the roller mechanism is slidably arranged in the slideway, and the hot core box mold can stably slide along the slideway through the roller mechanism.
[0005] Preferably, the roller mechanism comprises: a nut handle shaft, a shaft sleeve and a baffle, the nut handle shaft and the shaft sleeve are arranged in cooperation, and the nut handle shaft can be inserted into the shaft sleeve and fixed to the baffle.
[0006] Preferably, the roller mechanism and the hot box mold are fixedly mounted by bolts.
[0007] Preferably, the nut handle shaft, sleeve and baffle are made of quenched 25# steel.
[0008] The roller mechanism of the hot core box roller device provided by the utility model can not only slide stably on the slideway, but also is made of 25# steel by quenching, which effectively guarantees the service life and reduces the cost. At the same time, it is convenient to replace, simple to operate and highly practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and do not limit the utility model.
[0015] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.
[0016] See also Figure 1 , the utility model embodiment provides a hot core box roller device, the hot core box roller device comprising:
[0017] A hot box mold 1 and a roller mechanism 2, wherein the roller mechanism 2 is installed at the lower end of the hot box mold 1, and the hot box mold 1 can be moved by the roller mechanism 2; a slideway 3, which is arranged in cooperation with the roller mechanism 2, and the roller mechanism 2 is slidably arranged in the slideway 3, and the hot box mold 1 can stably slide along the slideway 3 through the roller mechanism 2.
[0018] The hot box roller device is suitable for a hot box mold 1 with a relatively heavy weight. The hot box mold 1 can stably slide on the slideway 3 through the roller mechanism 2, thereby ensuring the stable movement of the hot box mold 1.
[0019] like Figure 2 , Figure 3 and Figure 4 As shown, as a preferred embodiment of the utility model, the roller mechanism 2 includes: a nut handle shaft 21, a sleeve 22 and a baffle 23. The nut handle shaft 21 and the sleeve 22 are arranged in cooperation with each other, and the nut handle shaft 21 can be inserted into the sleeve 22 and fixed to the baffle 23.
[0020] During installation, the shaft 21 is inserted into the sleeve 22 using a nut and then fixed to the baffle 23 to form a roller mechanism 2. The roller mechanism 2 is installed on the hot core box mold 1 using bolts. When making cores, the roller mechanism 2 slides on the slideway 3 with the hot core box mold 1.
[0021] like Figure 1 As shown, as a preferred embodiment of the utility model, the roller mechanism 2 and the hot box mold 1 are fixedly installed by bolts.
[0022] The roller mechanism 2 can be quickly installed or removed from the hot box mold 1 by means of bolt connection.
