[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The following is combined with Figure 1-Figure 5 To further explain this application in detail,

[0028] The present application embodiment discloses a temperature control structure for an oven. Figure 1-Figure 5 The mold jaws positioning structure comprises a fixed mold 1; a movable mold 2 is installed above the fixed mold 1, the movable mold 2 is matched with the fixed mold 1, the movable mold 2 and the fixed mold 1 are symmetrically distributed, the inner end of the movable mold 2 is fixedly connected with a plurality of symmetrically distributed mold core blocks 4, and the inner end of the fixed mold 1 is provided with a plurality of symmetrically distributed jaws grooves 3, which are matched with the mold core blocks 4.

[0029] Positioning is performed through the jaws groove 3 and the mold core block 4. Compared with the common method of setting the jaws and the mold core at the four corners of the mold, this solution sets the jaws groove 3 and the mold core block 4 at the center position of the movable mold 2 and the fixed mold 1, and the jaws groove 3 and the mold core block 4 do not abut against each other, leaving enough space. When heated, the mold core block 4 will not abut against the jaws groove 3 even if it expands, preventing the mold core block 4 from expanding due to heat and biting the jaws groove 3. The influence of thermal expansion is small, and accurate positioning can be performed in various environments.

[0030] The fixed mold 1 includes a mold body 101, and the outer wall of the mold body 101 is fixedly connected to an anti-collision pad 102.

[0031] The mold body 101 is protected by the anti-collision pad 102 to prevent the mold body 101 from being damaged by external collisions, thereby improving the service life of the mold body 101 to a certain extent.

[0032] The movable mold 2 comprises a mold body 201 , and an anti-collision pad 202 is fixedly connected to the outer end of the mold body 201 .

[0033] The mold body 201 is protected by the anti-collision pad 202 to prevent the mold body 201 from falling and being damaged.

[0034] The thumb groove 3 includes a slot 301 , and an anti-slip pad 302 is fixedly connected to the inner wall of the slot 301 .

[0035] The anti-skid pad 302 increases the resistance of the slot 301 and improves the anti-skid coefficient.

[0036] The mold core block 4 includes a clamping block 401 , which is matched with the slot 301 , and an anti-slip edge 402 is fixedly connected to the outer wall of the clamping block 401 .

[0037] The anti-slip strength of the card block 401 is increased by the anti-slip edge 402, so as to prevent the card block 401 from falling off from the slot 301 when the card block 401 is subsequently engaged with the slot 301. The card block 401 and the slot 301 are elastic, and when the card block 401 expands due to heat, the card block 401 can be deformed as the card block 401 expands.

[0038] The top of the block 401 abuts against the bottom wall of the slot 301 , and the side wall of the block 401 does not abut against the side wall of the slot 301 .

[0039] Since the side wall of the clamping block 401 is not in contact with the side wall of the slot 301 , the clamping block 401 can be prevented from being stuck with the slot 301 after the clamping block 401 expands due to heat, thereby preventing the subsequent positioning from being affected.

[0040] Working principle: the mold body 101 and the mold body 201 are connected by the clamping block 401 and the slot 301, which is convenient for subsequent positioning. The side wall of the clamping block 401 is not connected to the side wall of the slot 301, which can prevent the clamping block 401 from biting with the slot 301 after the clamping block 401 expands due to heat, so as to prevent affecting the subsequent positioning. The anti-skid pad 302 increases the resistance of the slot 301 and increases the anti-skid coefficient. The anti-skid edge 402 increases the anti-skid strength of the clamping block 401, which is convenient for the subsequent clamping of the clamping block 401 and the slot 301 to prevent the clamping block 401 from falling off. The clamping block 401 and the slot 301 are elastic. When the clamping block 401 expands due to heat, it can be deformed with the expansion of the clamping block 401. The anti-knock pad 102 protects the mold body 101, and the anti-knock pad 202 protects the mold body 201.

[0041] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
